## Thinking Path
> - Paperclip Runner already has a hardened ACPX path for Codex.
> - Claude can reuse that protocol only with an exact package/model
profile and provider-lifetime fencing.

have the descriptor-confined verified launch used by the ACP server.

unavailable before installation or process launch.
## Linked Issues or Issue Description
**Subsystem affected**
Paperclip Runner ACPX driver, runtime host, sidecar, backend factory,
package dependency, and provider conformance tests.
**Problem or motivation**
The production ACPX backend was Codex-only. Claude needs the same
fail-closed model, authorization, cancellation, cleanup, and recovery
boundaries without exposing an unsafe secondary runtime path.
**Proposed solution**
Generalize the hardened ACPX runtime for the exact qualified `claude`
profile, add the pinned Claude ACP package and reviewed isolation patch,
and reject Pi before installation, backend construction, sidecar
initialization, Rust session admission, or process creation.
**Alternatives considered**
Activating Pi in this PR was rejected after security review because its
secondary runtime executable was pathname-based and lacked the verified
descriptor/snapshot boundary. Pi is deferred to a dedicated follow-up.
Replaying the older generic ACPX implementation was rejected because it
predates current hardening.
**Roadmap alignment**
ROADMAP.md does not list a conflicting ACPX-provider project. This
extends the existing Runner provider architecture.
## What Changed
- Generalized the ACPX backend, driver, runtime adapter, host, and
sidecar for the qualified Claude profile.
- Added Claude ACPX activation through its exact pinned package/model
pair and isolated-settings patch.
- Added provider-lifetime fencing for non-Codex qualified ACPX sessions.
- Kept Pi dependencies and its patch out of the package and build
configuration.
- Added fail-closed Pi rejection at driver validation, backend
construction, runtime-host admission, sidecar initialization, and Rust
session validation.
- Added focused tests for Claude selection, model enforcement, lifecycle
fencing, cancellation, recovery, and Pi rejection.
- Did not change or commit `pnpm-lock.yaml`; CI regenerates the PR
lockfile under the existing repository policy.
## Verification
- GitHub Actions is the authoritative verification environment for this
PR.
- CI runs dependency policy, runner package checks, protocol parity,
typecheck, build, security, and stack policy.
- Local tests were not run because this checkout is resource
constrained, per the requested workflow.
## Risks
- Claude package behavior can drift from the qualified protocol; the
package and patch are pinned and admission verifies the exact profile.
- Unsupported providers and models fail closed.
- Pi remains unavailable until descriptor-confined verified launch
exists for its separate runtime.
- Existing Codex ACPX behavior remains covered by shared conformance
tests.

## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting: packages/paperclip-runner and the Codex-local adapter
configuration contract.
**Problem or motivation**
Paperclip Runner has provider-neutral contracts, but the production
backend factory cannot start a qualified OpenCode session. This blocks
OpenCode from using the durable runner path.
**Proposed solution**
Add the qualified OpenCode app-server proxy, driver, MCP bridge,
backend, fixtures, and factory wiring. Keep existing Codex behavior
unchanged.
**Alternatives considered**
Keeping OpenCode only on the direct adapter path would avoid this
runtime work, but it would not provide durable runner recovery or
normalized provider events.
**Roadmap alignment**
ROADMAP.md does not list a conflicting provider-runtime project. This
change extends the existing Paperclip Runner architecture.
## What Changed
- Added the qualified OpenCode app-server proxy and input queue.
- Added collaboration-mode and provider-event normalization.
- Added the OpenCode MCP bridge and native session backend.
- Added strict fixtures and focused unit coverage.
- Added only the package exports and adapter configuration required by
this runtime.
- Kept deferred SDK, lab, eval, and public package surfaces out of this
change.
## Verification
- GitHub Actions is the authoritative verification environment for this
PR.
- Run the package type checks and focused OpenCode tests in CI.
- Run repository typecheck, test, build, security, and policy gates
through the stack-aware workflow.
- Local tests were not run because this checkout is resource
constrained.
## Risks
- OpenCode protocol changes could affect event normalization or
recovery.
- The driver fails closed on malformed input and unsupported runtime
behavior.
- Existing Codex selection remains unchanged unless the stored provider
is OpenCode.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Rust ACPX session can now suspend only at a safe idle boundary
and its events have a durable projection
> - A later runner process cannot safely resume from an unbound or
partially written identity record
> - The recovery anchor must bind the exact provider identity, run,
normalized session, catalog revision, and catalog digest
> - The record must be bounded, private, strict about schema drift, and
atomically replaceable

before releasing the stored identity
> - This pull request adds only that package-local checkpoint store
without selecting ACPX in runnerd
## Linked Issues or Issue Description
Refs #12424
Refs #12422
## What Changed
- Add a versioned ACPX safe-suspension checkpoint contract with unknown
fields rejected at every persisted level.
- Bind each checkpoint to the run, normalized session, catalog revision,
catalog digest, and exact provider identity.
- Persist a checkpoint-specific strict identity that requires the pinned
permission mode without narrowing the additive live sidecar identity
wire shape.
- Construct checkpoints only from a session configuration whose model,
permission policy, tool catalog, and expected identity validate.
- Admit recovery only when reconstructing the checkpoint from the
prospective configuration produces an exact match.
- Reject run, session, catalog revision, catalog digest, model,
permission, expected-identity, profile, and workspace drift fail closed.
- Require persisted run/session IDs to satisfy the same stable-ID
boundary as fresh session admission.
- Store the checkpoint under a dedicated private runner-state
subdirectory.
- Bound checkpoint files to 1 MiB before reading or decoding.
- Refuse symlinked state directories and non-private or non-regular
checkpoint files.
- Replace checkpoints atomically through a private temporary file and
directory sync.
- Make repeated saves of the same checkpoint idempotent.
- Add integration coverage for private round trips, complete recovery
admission, malformed/oversized files, nested schema drift, missing
permission binding, invalid stable IDs, and symlink denial.
- Document the package-local suspension recovery boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.
## Verification
- Replay base: `1ee738cf487defe88043b241c4e2dc34a1a8a7bc` (`master`
after #12424 merged).
- Exact replay head: `89cfea5495428be890810d2b8a27673943234ca3`.
- Stable patch ID: `dbaeb0bbe773f1ca5ef1f9bdc0fa61f4a08ca451`.
- The exact delta is 4 files and 591 additions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,
UI, dependency, or migration change.
- `git diff --check` and the Cargo formatting check pass on the replayed
delta.
- Exact-head GitHub Actions run `33374006661` (attempt 2): **PASSED**
with 23/23 jobs passed.
- Greptile reviewed exact head
`89cfea5495428be890810d2b8a27673943234ca3`: **5/5**, with zero
unresolved review threads.
- Superagent, contributor trust, Socket, and Snyk security checks:
**PASSED**.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- A checkpoint is valid only after the sidecar has confirmed safe
suspension. The constructor therefore accepts the exact identity
returned by that operation and revalidates it against local authority.
- Loading proves only that the file is structurally valid;
`admit_recovery` is the boundary that proves the file belongs to the
prospective run, catalog, model, permission policy, and expected
provider identity.
- The checkpoint intentionally contains no credentials, bootstrap
ticket, provider output, or pending request payload.
- Strict checkpoint schema and identity validation rejects incompatible
or tampered recovery records rather than attempting partial migration.
This strictness is checkpoint-local and does not narrow existing PRP or
sidecar wire compatibility.
- Atomic replacement uses the platform `rename` primitive; Unix
additionally syncs the private parent directory before reporting
success.
- No production path loads this checkpoint in this pull request. Runnerd
execution and durable recovery wiring remain a later slice.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Rust runner now owns validated, scoped ACPX reducer events and
safe session suspension
> - Durable PRP transport must receive provider-neutral events rather
than sidecar-native envelopes
> - Semantic calls and questions must retain the exact run, session,
turn, item, and provider-request authority used by the durable command
stream
> - Terminal, result, assistant, process, and diagnostic events also
need one reviewed projection boundary
> - Permission requests remain impossible under the pinned Codex policy
and must fail closed if they reach projection

## Linked Issues or Issue Description
Refs #12422
## What Changed
- Add a validated durable ACPX event projection context bound to one
run, normalized session, turn, and item.
- Pass already normalized activity events through without reintroducing
provider-native envelopes.
- Project authorized tool calls into canonical semantic input receipts
with exact correlation and content digests.
- Project structured questions into provider-neutral
`paperclip.runtime_request.v2` events.
- Preserve both the public projected request identity and the original
provider request identity so responses resolve the exact sidecar
request.
- Project dynamic semantic operation results as `semantic_tool.result`;
only reserved finish/block operations may propose the run result.
- Project semantic completion results into `run.result.proposed`.
- Project terminal-flushed assistant messages on the final channel and
turn terminal states into existing provider-neutral event families.
- Project sanitized process metadata and diagnostics into bounded
harness diagnostics.
- Validate runtime-request origins against their strict durable shape
and fall back from empty optional titles to a valid question prompt.
- Reject invalid identities, projected-identity collisions, unstable
semantic receipt identities, permission requests, and cross-turn
projection fail closed.
- Add integration coverage across reducer event families, correlation,
identity validation, projected question resolution, and pinned-policy
denial.
- Document the durable projection boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.
## Verification

**PASSED**.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- This function accepts reducer output, not raw sidecar frames. Callers
must preserve the existing scope-first decode and reduction order.
- Semantic input includes the already sanitized provider input while its
content receipt uses the same canonical digest.
- Structured input preserves the validated provider-neutral question set
and sanitized origin.
- Noncanonical provider request identities are deterministically
projected for PRP while the original identity remains authoritative for
the sidecar resolution command.
- Existing PRP v1 identifiers remain schema-compatible; the only public
ID-schema change widens turn/item limits from 160 to 240 characters. The
internal ACPX sidecar wire schema now mirrors the stable IDs its Rust
transport already enforced.
- The projector verifies event-carried terminal and assistant turn
identifiers against the durable context.
- No production path invokes this projector in this pull request.
Durable command execution remains the next slice.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Rust runner now owns exact ACPX request resolution and
fail-closed session state
> - A recoverable provider session needs an explicit suspension boundary
before runnerd can safely hand work across process lifetimes
> - Suspension is unsafe while a turn or provider request is active
because remote effects may still be in flight
> - A successful acknowledgement must preserve the exact immutable
session identity
> - This pull request adds only that guarded package-local lifecycle
operation without selecting ACPX in runnerd
> - The benefit is a small recovery primitive whose safety rules are

## Linked Issues or Issue Description
Refs #12421
## What Changed
- Add a provider-state query for active pending tool, input, or
permission requests.
- Permit session suspension only when no turn or provider request is
active.
- Send a bounded `session.suspend` command with an operator-safe reason.
- Require an affirmative suspension acknowledgement and the exact
existing session identity.
- Treat transport failure, rejection, omitted or malformed identity, and
identity drift as fail-closed terminal errors.
- Mark a successfully suspended session closed and terminate the local
sidecar process while retaining cleanup ownership if termination must be
retried.
- Preserve a valid session after purely local unsafe-state rejection so
it can settle before retry.
- Extend the fake sidecar with deterministic suspension success,
acknowledgement mismatch, identity mismatch, and missing-identity modes.
- Add integration coverage for safe suspension, active-turn rejection,
fail-closed remote mismatches, and retained cleanup.
- Document the package-local suspension boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.

**PASSED**.
- No local test result is claimed. GitHub Actions is the authoritative

## Risks
- The sidecar may apply suspension before a transport failure is
observed. The local session closes rather than retrying an ambiguous
effect.
- Local active-work rejection happens before transport and leaves the
valid session open so the caller can settle it safely.
- Identity equality is checked across provider, driver, session, thread,
run, and company fields before accepting suspension.
- No production path invokes suspension in this pull request. Runnerd
execution and durable recovery wiring remain later slices.

## What Changed
- Resolve authorized semantic tool calls only for the active turn and
exact pending operation.
- Validate semantic results against the authorized response schema
before transport.
- Send a bounded generic provider error when a semantic operation fails
without exposing internal error text or payloads.
- Resolve structured input only after validating the exact persisted
question set.
- Support explicit submit, decline, and cancel input outcomes.
- Reject any Codex permission event that bypasses the pinned sidecar
policy.
- Build candidate provider and authorization state before each request.
- Commit candidate state only after the sidecar returns an affirmative
resolution acknowledgement.
- Preserve pending work after local validation errors so the caller can
retry safely.
- Terminate the session after transport failure or an invalid remote
acknowledgement because the remote effect is ambiguous.
- Bind every resolution to the exact active turn and request or call
identity.

threads; Superagent, Socket, Snyk, and contributor-trust checks also

- No local test result is claimed. GitHub Actions is the authoritative

## Risks
- A transport failure can happen after the sidecar applied a resolution.
The session closes instead of retrying an ambiguous effect.
- Local validation happens before transport and preserves pending state,
so a corrected answer or result can be retried.
- The sidecar transport already correlates each command response to its
request identifier. This slice also requires `resolved: true` before
local commit.
- The initial Codex sidecar owns its pinned permission policy and does
not delegate permission resolution. Any permission event therefore
terminates the session fail closed.
- No production path invokes these methods in this pull request. Durable
ACPX execution wiring remains a later slice.

- Validate duplicate option IDs, inverted bounds, and dynamic patterns
before answer lookup so malformed optional questions fail closed even
when unanswered.
- Match JavaScript UTF-16 code-unit length semantics for text
constraints and the 100,000-unit response-field bound.
- Preserve the public optional `recommended` question-option field in
the versioned schema, generated schema bundle, and Rust validation path.
- Return typed validation errors for malformed inputs without panics.
- Export the validator from the Rust runner core.
- Add table-driven tests for valid, mismatched, malformed, oversized,
and numeric-boundary responses.
- Document the package-local structured-response boundary.
- Add `num-bigint` 0.4 and `num-traits` 0.2 as direct runner-core
dependencies for exact arbitrary-length radix parsing and one-step
JavaScript Number rounding; update only the package-local runner Cargo
lockfile.
- Do not change the repository PNPM lockfile, workflows, runnerd
selection, server behavior, UI, or migrations.
## Verification
- Replay base: `9a9fdf06ee4142f77427db30efccc4c43056f64b` (`master`
after #12419 merged).
- Exact replay head: `fad92b3fb348b66ddb10dde44b7b060e55c4fe96`.
- Stable patch ID: `4d6ffbd519dd081f7ea530977cd965bd4569fc75`; this is
the prepared two-commit delta plus the focused cross-language parity fix
found during replay review.
- The exact delta is 10 files, 712 additions, and 2 deletions, all in
`packages/paperclip-runner`.
- The package-local `packages/paperclip-runner/runner/Cargo.lock`
records the two direct runner-core dependencies; their already-resolved
versions and checksums are unchanged.
- The question-set schema source, generated TypeScript schema bundle,
and protocol manifest hash are updated together; the schema SHA-256 is
`42b5441a3d388851dacb6e4500dfd4a17d878eded2e724228078b647e7440d3f`.
- GitHub Actions run `33366812025`, attempt 2: **PASSED** on the exact
replay head (23/23 jobs passed; a failed-job-only retry cleared one
unrelated ACPX runtime-host timeout).
- Greptile: **5/5** on the exact replay head with zero unresolved review
threads; Superagent, Socket, Snyk, and contributor-trust checks also
passed.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- The validator compiles the embedded response schema for each
submission. Responses are user-paced and bounded, so this keeps the
slice simple without affecting a hot event path.
- The persisted question set is the source of truth for identifiers and
constraints. A malformed persisted set fails closed.
- Numeric input follows the existing structured-question contract,
including JavaScript-prefixed syntax. Optional whitespace-only answers
are rejected instead of being treated as an omitted value.
- Error messages identify the invalid field but do not include answer
text.
- No production path invokes this validator in this pull request.
Request resolution remains the next slice.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Rust runner now validates and opens an exact Codex ACPX session
and attaches one run/catalog identity
> - A live session must start one turn, preserve immutable workspace
authority, accept interruption, and consume provider events
> - Command acknowledgements and event scope are trust boundaries;
disagreement must terminate the session rather than permit divergent
state
> - The existing reducer already owns bounded state, ordering,
correlation, and terminal cleanup
> - This pull request connects turn commands and polling only to that
reviewed reducer without selecting ACPX in runnerd
> - The benefit is a fail-closed execution loop before semantic request
resolution and production selection are added
## Linked Issues or Issue Description

Refs #12417
## What Changed
- Start one ACPX turn only after validating a bounded turn identifier,
bounded message, and the session's immutable working directory.
- Require `turn.start` to acknowledge the exact requested turn before
mutating provider state.
- Request interruption only for the active turn and require an
affirmative cancellation acknowledgement.
- Keep the turn active until the authoritative terminal event is polled
and reduced.
- Poll bounded sidecar events and route every event through the existing
scope-first payload/state boundary.
- Terminate the sidecar fail closed after a rejected or mismatched turn
command, transport failure, or invalid scoped event.
- Preserve ordinary local validation failures without mutating or
closing an otherwise valid session.
- Admit semantic tool calls through the run-scoped authorized tool
bridge before returning them to runnerd.
- Reduce events and authorize tool calls on candidate clones, then
commit both together only after every check passes.
- Rotate and scope tool receipts by run and turn; reserve pending,
completed, and settled call IDs across both tool bridges so cross-bridge
duplicates cannot be re-admitted.
- Preserve exact turn correlation through payload, scope, provider
state, fake sidecar, and integration fixtures.
- Extend the package-local fake sidecar with deterministic turn
activity, terminal, acknowledgement-mismatch, and scope-violation modes.
- Add integration coverage for happy-path
activity/interruption/settlement, local validation, turn mismatch,
cancellation mismatch, cross-run denial, receipt rotation, and
cross-bridge call-ID reuse.
- Document the turn lifecycle boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.
## Verification
- Replay base: `10cf68295d5457ccf1010db20a06e2951e47162a` (`master`
after #12418 merged).
- Exact replay head: `1ec18368bdacafafa58720b9e2b982e1b0d11163`.
- Stable patch ID: `4b43a5ef2a428850a05b0741d06e7cf4f48ec334`, identical
to the prepared four-commit delta plus the focused cross-bridge call-ID
reservation fix.
- The exact delta is 13 files, 1,855 additions, and 37 deletions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,
UI, or migration change.
- GitHub Actions run `33364033038`, attempt 2: **PASSED** on the exact
replay head (23/23 jobs passed; the failed-job-only retry cleared one
unrelated flaky server heartbeat test).
- Greptile: **5/5** on the exact replay head with zero unresolved review
threads; Superagent, Socket, and Snyk checks also passed.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- A sidecar may emit events while a command response is in flight. The
transport buffers them, then the session binds the acknowledged turn
before polling and reducing those events.
- A turn-start rejection can leave provider-native state ambiguous, so
command rejection or acknowledgement mismatch terminates the session
instead of attempting unsafe reuse.
- Interruption does not settle local state; only the validated terminal
event clears the active turn.
- Any transport or event validation failure terminates the child process
so a compromised stream cannot continue.
- Call identifiers are authorization identities and remain reserved
across pending, completed, and settled states in both bridges.
- The package exposes new Rust methods, but no production path invokes
them in this pull request.
- Tool authorization is atomic with reducer state, but tool results,
structured input, and permission resolution remain later slices.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Rust runner now has bounded ACPX transport, scope, payload,
normalization, and state-reduction layers
> - A live provider needs a lifecycle owner that starts the sidecar and
proves it opened the exact requested session
> - The initial production slice is Codex-only and must fail closed on
capability, model, identity, policy, or catalog drift
> - Failed bootstraps must not leak a child process, and ordinary
shutdown must preserve resumable provider state

commands and production selection are connected
## Linked Issues or Issue Description

Refs #12416
## What Changed
- Add a package-local ACPX provider session configuration and lifecycle
owner.
- Reject non-UTF-8 runtime and working directories before spawning so
JSON path serialization cannot panic.
- Validate the sidecar launch contract, Codex-only agent, model, run and
session identifiers, absolute directories, positive JSON-safe catalog
revision, pinned permission mode, bounded instructions, and canonical
authorized tool catalog before spawning.
- Verify the initialization protocol version, child PID,
persistent-session support, exact-model support, runner-owned permission
policy, semantic-tool bridge, and structured-input contract.
- Open an identity-bound session and require the requested and effective
models, permission mode, session identifier, digests, and optional
recovery identity to match exactly.
- Attach the run and require the sidecar to confirm the exact run
identifier and catalog revision.
- Retry failed transport cleanup while retaining lifecycle ownership;
terminate the sidecar after every failed bootstrap and on an unclosed
session drop.
- Close sessions without discarding persistent state and make explicit
shutdown idempotent.
- Extend the package-local fake sidecar with deterministic bootstrap,
wrong-model, and wrong-run responses.
- Add five integration tests covering successful bootstrap/shutdown,
pre-spawn policy validation, model mismatch, run mismatch, and recovery
identity matching.
- Document the session bootstrap boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.
## Verification
- Replay base: `f038633bf5b04163ff985ef0542876bd9f455379` (`master`
after #12417 merged).
- Exact replay head: `a6d9ad62f20fdb47a1dbc76aa4baa9d8fa6dae53`.
- Stable patch ID: `82b6f2551749598a688c3f44a1a3714516030429`, identical
to the reviewed `e6e550f9..d51a8855` delta.
- The exact delta is 5 files and 609 additions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,
UI, or migration change.
- Focused Rust lifecycle, package, repository, security, and Greptile
checks: **PASSED** on the replayed exact head. Full CI run `33362799786`
is green; its failed-job retry passed one unrelated flaky server shard
without a patch change. Greptile is exact-head 5/5, all security checks
pass, and no review threads remain unresolved.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- This lifecycle owns a child process and session identity.
Configuration is fully validated before spawning, every bootstrap
response is checked against the child PID and requested identity, and
failed bootstrap always terminates the process.
- Recovery identity matching is exact so a persisted native record
cannot silently attach to another session, model, workspace, profile, or
permission policy.
- Explicit shutdown preserves persistent provider state; a dropped
unclosed session still terminates its process group as a safety
fallback.
- The package exports a new Rust module, but no production path
constructs it in this pull request.
- Turn commands, event polling, request resolution, and runnerd
selection remain later slices.

work

requests and preserve turn ordering

## Linked Issues or Issue Description

Refs #12415
## What Changed
- Add a package-local ACPX provider state reducer with one run binding
and one active turn.
- Decode every sidecar event through the existing scope-first payload
boundary before state mutation.
- Bound retained assistant text, pending semantic tool inputs, and
pending runtime request values.
- Correlate semantic tool calls, structured input requests, and
permission requests by stable IDs.
- Keep pending tool resolution two-phase so callers remove state only
after a later sidecar command succeeds.
- Carry authoritative tool classification from validated payloads into
retained state.
- Suppress repeated reasoning-start activity within one turn.
- Accept one semantic result idempotently and fail closed on a
conflicting result.
- Flush the final assistant message before the authoritative terminal
event.
- Clear unresolved turn-scoped requests at terminal state and reject
late events for the settled turn.
- Admit redacted global process and diagnostic events without requiring
an active turn.
- Add seven integration tests for turn ordering, correlation, conflicts,
scope-before-mutation, redaction, and terminal cleanup.
- Document the state boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.
## Verification

to the reviewed `f9cb4e54..e6e550f9` delta.
- The exact delta is 4 files and 720 additions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,
UI, or migration change.
- Focused Rust state, package, repository, security, and Greptile
checks: **PASSED** on the replayed exact head. Full CI run `33362166929`
completed successfully, Greptile is exact-head 5/5, all security checks
pass, and no review threads remain unresolved.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- This reducer owns security-sensitive correlation and terminal
ordering, so its only raw-event entry point always invokes scope-first
decoding.
- Pending resolution methods must be called only after the corresponding
sidecar transport command succeeds; the later process adapter owns that
sequencing.
- Terminal events intentionally clear unresolved turn-scoped requests so
late tool or input results fail closed.
- One semantic result remains readable after terminal state for later
durable finalization and is cleared only when a new turn begins.
- The package exports a new Rust module, but no production path
constructs it in this pull request.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Rust runner now admits ACPX sidecar frames only after transport,
scope, and payload validation
> - Valid payloads still contain provider-native runtime event shapes

## Linked Issues or Issue Description

## What Changed
- Normalize validated ACPX text, reasoning, plan, status, tool, notice,
and error updates into existing PRP activity families.
- Keep reasoning contents private while preserving a reasoning activity
boundary.
- Map plan entries, usage, review-mode status, and tool lifecycle into
bounded canonical payloads.
- Generate one shared ACPX sidecar event/classification contract for
TypeScript and Rust, with ASCII-only classification parity and bounded
kind/title fields.
- Preserve authoritative tool-call identity and classification even when
the aggregate native event exceeds the generic frame budget.
- Resolve display-only tool targets within the workspace under the
provider host's path semantics; reject raw, unmarked, absolute,
parent-traversing, URL-shaped, and unsafe drive-shaped values.
- Redact and digest retained tool output with the existing durable
policy.
- Ignore provider inventory status updates that have no user-facing
activity.
- Leave semantic results and `done` updates to the stateful adapter so
durable receipts and terminal events are not duplicated.
- Add cross-language and Rust coverage for every mapping family,
classifier parity, privacy, unsafe paths, redaction, bounded
titles/kinds, and oversized tool-call preservation.
- Document the normalization and display-path authorization boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.

successfully, Greptile is exact-head 5/5, all security checks pass, and
no review threads remain unresolved.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- This code controls what provider activity is retained and displayed,
so malformed native values must not bypass the earlier decoder.
- The function contract requires an already scope-checked and
payload-validated runtime event; the future adapter must preserve that
order.
- Tool classification and identity are security-relevant authorization
inputs and remain explicit even when optional aggregate display data is
dropped for bounds.
- Repeated reasoning chunks require stateful suppression. This mapper
exposes a privacy-safe start boundary and the later adapter owns
per-turn deduplication.
- Semantic results and terminal authority intentionally produce no
activity here; the later adapter must commit them through the durable
operational paths.
- The package exports new generated and Rust normalization surfaces, but
no production path invokes them in this pull request.

## Linked Issues or Issue Description
Refs #12414
Refs #12412
## What Changed
- Decode sidecar payloads only after run and turn scope validation
passes.
- Limit each decoded payload to 256 KiB.
- Add typed payload variants for runtime events, permission requests,
input requests, semantic tool calls, terminal events, process events,
and diagnostics.
- Admit only the nine runtime event shapes emitted by the reviewed Codex
ACPX sidecar.
- Validate runtime text, plan entries, tool locations, semantic result
identities, notices, errors, and terminal status values.
- Validate input requests against `paperclip.question_set.v1`.
- Reject duplicate question IDs and duplicate option IDs within one
question.
- Require bounded control identities and object-shaped operational
values.
- Redact diagnostic, error, process, permission, tool, and retained
runtime values before they can enter provider state.
- Add six integration tests for every admitted shape, malformed values,
scope-before-decode ordering, size limits, question ambiguity, and
secret redaction.
- Document the payload boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.

## Risks
- This decoder is a security boundary because later code can act on

## What Changed
- Add an `AcpxEventScope` for one run and at most one active turn.
- Validate run and turn identifiers before they enter scope state.
- Make repeated binding of the same turn safe.
- Reject a second active turn and a stale turn clear.
- Require exact run and active turn bindings for operational, tool,
input, permission, and terminal events.
- Permit process and diagnostic events without a scope because they can
describe the sidecar process itself.
- Validate every optional run or turn binding on process and diagnostic
events.
- Add an integration-test file for all seven event families, missing
scope, cross-run scope, cross-turn scope, inactive turns, turn
lifecycle, and invalid identifiers.
- Document the event authorization boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.
## Verification
- Replay base: `75708fec6d421a247ba2fc832997de24ed10a085` (`master`
after #12412 merged).
- Exact replay head: `88bb248442b8f628c20e977d2c2dbc21d85fb6dd`.
- Stable patch ID: `0b6443b1bc32ed244f650936026367dd84bcfd65`, identical
to the reviewed `c5654218..972a3b38` delta.
- The exact delta is 4 files and 280 additions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,
UI, or migration change.
- Focused Rust scope, package, repository, security, and Greptile
checks: **PASSED** on the replayed exact head. Full CI run `33360199404`
completed successfully, Greptile is exact-head 5/5, all security checks
pass, and no review threads remain unresolved.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- Event scope is a security boundary because it rejects data from
another run or turn.
- The validator fails closed on missing, malformed, stale, or
cross-scope identifiers.
- Process and diagnostic events can remain global, but any scope they
provide must be valid.
- The package exports a new Rust module, but no production path
constructs it in this pull request.
- A later provider adapter must bind and clear the exact turn around
each sidecar turn.

## What Changed
- Add a Rust client for the generated ACPX sidecar v2 contract.
- Validate the executable path, launch arguments, request timeout, and
shutdown grace before process start.
- Require exact request identities and contiguous event sequence
numbers.
- Reject replayed events, sequence gaps, wrong response identities,
malformed frames, unknown fields, and unsupported protocol versions.
- Bound stdout frames to 1 MiB and buffered events to 512 entries.
- Bound event poll timeouts to 120 seconds before any `Instant`
arithmetic.
- Buffer valid events that arrive while a command waits for its
response.
- Treat an empty event poll as a normal timeout without poisoning the
transport.
- Discard retained events and reject all polling after a terminal
transport failure.
- Terminate the process group after a timeout, transport failure, or
protocol failure.
- Keep a valid sidecar command rejection separate from a transport
failure so the next command can run.
- Redact and bound stderr diagnostics before they enter an error.
- Add a deterministic fake sidecar and twelve integration tests for
success, polling, timeout bounds, poisoned queues, replay, gaps,
identity mismatch, rejection, event floods, oversized frames, and secret
redaction.
- Document that the transport remains package-local and does not change
runnerd provider selection.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.
## Verification
- Replay base: `9ad8dbffa0a4759dcda2769042d6e8f02adcdf8d` (`master`
after #12410 merged).
- Exact replay head: `5c41111c4f9564405a6e87a02b6cf253a4424e5f`.
- Stable patch ID: `60aca2620fdbb73fbbc203e928d39dcd450e085b`; this
preserves the reviewed `1334a7f5..c5654218` six-file delta and keeps
trusted bounded-reader failures distinct from fully redacted child
stderr.
- The exact delta is 6 files and 896 additions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,
UI, or migration change.
- Focused Rust transport, package, repository, security, and Greptile
checks: **PASSED** on the replayed exact head. Full CI run `33359202433`
is green; its failed-job retry passed the two unrelated flaky jobs
without a patch change. Greptile is exact-head 5/5, all security checks
pass, and no review threads remain unresolved.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## Risks
- The transport crosses an untrusted process boundary and is
security-sensitive.
- It fails closed on malformed frames, identity drift, event replay,
sequence gaps, queue overflow, frame overflow, timeout, process exit,
and channel failure.
- A terminal failure clears retained events before it marks the
transport unavailable.
- It redacts and bounds retained diagnostics before it returns them to a
caller.
- A valid remote command rejection does not corrupt the transport state.
- The package exports a new Rust module, but no production path
constructs it in this pull request.
- The later provider adapter must validate run, turn, session, model,
and tool bindings before it selects this transport.

## Linked Issues or Issue Description
Refs #12409
Refs #12386
This pull request implements the Codex-only executable for the ACPX
sidecar contract merged in #12386. It builds on the question conformance
gate merged in #12409. Runnerd and the server do not select this
executable in this pull request.
## What Changed
- Publish the `paperclip-runner-acpx-sidecar` package binary and
document its current boundary.
- Add a versioned stdin/stdout sidecar that admits only the qualified
Codex ACPX profile and exact initialized model.
- Support atomic session open, run attachment, turn start and
cancellation, tool and input resolution, session read and snapshot, safe
suspension, close, and recovery identity checks.
- Bind runtime directory, workspace, permission mode, provider identity,
run identity, and semantic tool catalog before use.
- Validate completion and blocked results against the PRP result
contract. Bound pending tools, pending inputs, messages, events, usage,
diagnostics, and errors.
- Redact provider output and convert file locations to bounded
workspace-relative display data. Do not treat displayed paths as
file-access authority.
- Harden verified executable loading, module resolution, launch
environment filtering, process-group guardianship, and provider
termination.
- Retain managed credentials and every failed-admission resource until
the exact provider cleanup proves ownership was released.
- Keep failed-admission cleanup alive with bounded backoff until the
provider exits. Do not scrub credentials or admit a replacement while
cleanup still owns the provider.
- Use one runtime-host cleanup-owner registry and preserve sequential
cleanup retries across command timeouts and shutdown.
- Arm a credential-free same-group watchdog before provider admission so
guardian death reaps even a stopped provider; retain an independent
kernel EOF proof before releasing credentials.
- Add sidecar process, lifecycle, location, package, driver, credential,
installation, runtime-adapter, and runtime-host regression tests.
- Add `tsx` as a package test-only development dependency for the real
TypeScript sidecar process test.

- The resolved combined delta is 4,725 additions and 665 deletions; it
preserves the lower-PR runtime-close semantics, repairs stale
successful-admission fixtures, deterministically observes renewed
reconciliation, accepts authoritative same-host cleanup recovery without
dropping pending owners, ignores superseded cleanup failures after a
newer owner recovers, and requires both guardian exit and independent
provider-lifetime EOF before releasing cleanup or credential ownership.
A readiness-gated, credential-free watchdog also reaps a stopped
provider if its guardian is externally killed.
- This change updates the runner package manifest, README, and test-only
dependencies. It does not change `pnpm-lock.yaml`, a workflow,
migration, server route, UI path, runnerd selection, or current
direct-adapter behavior.
- Focused GitHub verification: **PASSED** for the sidecar process,
lifecycle, location, package-contract, driver, credential,
installation-integrity, runtime-adapter, and runtime-host suites on the
replayed head.
- Package verification: **PASSED** for the clean tarball, Node shebang,
and exact binary mapping on the replayed head.
- GitHub Actions and security checks: **PASSED** for the replayed exact
head; full CI run `33357846557` completed 23/23 jobs successfully, and
Superagent, Socket, Snyk, supply-chain, and contributor-trust checks are
green. Storybook was intentionally skipped because this PR does not
touch its paths.
- Greptile: **5/5** on the exact head with zero unresolved review
threads.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for the replayed revision.
## Risks
This change has medium security and lifecycle risk because the new
executable crosses a process, credential, filesystem, and provider
boundary. The sidecar fails closed on unsupported providers, models,
permissions, identities, catalogs, forms, commands, and persistent-state
deletion. A cleanup owner can remain alive until a stubborn provider
exits. Its retries use bounded backoff, and admission stays closed while
ownership remains. Command and shutdown waits remain bounded without
abandoning the underlying cleanup. The new `tsx` dependency is
development-only. The package exposes a new binary, but no runnerd,
server, UI, or direct-adapter path starts it in this pull request.

## Linked Issues or Issue Description
Refs #12408
This pull request builds on the Codex ACPX question bridge merged in
#12408. It adds fixture and generator checks for the existing Codex and
ACPX question adapters. It does not add another provider or production
execution path.
## What Changed
- Add a canonical ACPX form fixture and native response. Mark the
equivalent Codex fixture field as required.
- Add shared validation for question IDs, option IDs, answer modes,
required answers, text bounds, numeric bounds, and response shapes.
- Evaluate fixture-only regular expressions in a bounded child process.
Reject patterns that cannot finish safely.
- Validate ACPX fixtures against a manifest-side mirror of the
production form projection. Reject free-text ACPX patterns, but ignore
patterns on enumerated option fields.
- Accept explicit empty optional answers and omit them from the
projected ACPX response, which matches the production parser.
- Validate every question fixture during manifest generation and
regenerate the checked-in manifest.
- Add cross-adapter tests that compare user-visible presentation while
preserving provider-owned IDs and provider-specific response conversion.
- Add negative regressions for malformed forms, invalid responses,
unsafe patterns, special property names, and projection drift.

## Risks
This change has low runtime risk because it changes fixtures, generator
validation, generated metadata, and tests only. Fixture pattern checks
run in a child process with a one-second timeout and a bounded output
buffer. The ACPX gate intentionally rejects free-text patterns because
the production adapter has no bounded expression engine. It
intentionally permits an explicit empty optional answer because
production omits that answer from the native response. A validation
mismatch can block manifest generation, but it cannot change server
selection, direct adapters, or task-page behavior.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The runner package gives provider sessions one normalized execution
contract.
> - The merged Codex ACPX path can run and recover settled turns.
> - It cannot yet send a structured provider question through the

## Linked Issues or Issue Description
Refs #12407
This pull request builds on the settled Codex ACPX recovery path merged
in #12407. It adds only package-local structured-question support for
Codex ACPX sessions.
## What Changed
- Enable ACPX form elicitation for the Codex runtime and pass its
handler through the runtime host boundary.
- Normalize ACPX forms to `paperclip.question_set.v1` and emit
`paperclip.runtime_request.v2` events.
- Validate `paperclip.question_response.v1` resolutions before
conversion to ACP form responses.
- Support explicit resolution and durable handoff. Cancel pending
requests on provider abort, stream failure, turn settlement, and session
close.
- Limit each session to 16 pending requests. Reject unsupported input
modes, regular expression patterns, session-wide acceptance, stale
turns, and late responses.
- Fail closed under bounded event-queue pressure: cancel an input whose
creation event cannot be retained, and preserve a live request when its
durable-handoff event cannot be retained.
- Persist pending-request facts in snapshots and reject recovery while a
provider request is still pending.
- Add focused driver, runtime-adapter, and runtime-host regression tests
for round trips, aborts, stream failures, handoff, and handler
forwarding.

## Risks
This change has medium package-local risk because it connects
provider-owned input to durable runner state. Unsupported modes and
unbounded patterns fail closed. The pending-request limit bounds
retained provider state. Provider abort, turn settlement, stream
failure, and session close cancel live questions. A durable handoff
expires the request before it interrupts the turn. Recovery rejects a
snapshot that still contains a pending provider request. Existing direct
adapters, server selection, and task-page behavior do not use this
route.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The runner package keeps provider sessions durable across process
restarts.
> - The merged Codex ACPX backend can admit a new qualified session
through the package factory.
> - It cannot yet recover a settled session from a durable checkpoint.
> - Recovery must prove the same provider identity, runtime root,
workspace, and latest terminal settlement before it resumes.
> - ACPX cannot yet prove continuity for a provider turn that was active
when the process stopped.
> - This pull request recovers only settled Codex ACPX checkpoints and
rejects ambiguous or stale state.

silent session replacement, or recovery of an older semantic result.
## Linked Issues or Issue Description
Refs #12406
This pull request builds on the Codex ACPX backend route merged in
#12406. It adds only settled-session recovery and the package-local
durability and filesystem checks that recovery requires.
## What Changed
- Add settled-session recovery to the Codex ACPX harness driver and
advertise resume support for that bounded path.
- Keep provider recovery on the same persisted ACPX session. Do not
permit a replacement provider session.
- Require persisted run, normalized session, provider, profile,
workspace, permission, result, terminal, and recovery-policy identities
to agree.
- Reopen the provider with the exact persisted ACPX identity and reject
provider or qualification drift.
- Restore the last source sequence, terminal history, semantic result,
provider recovery policy, and normalized terminal fact before new work
can start.
- Clear a stale active-turn marker only when durable terminal history
proves that exact turn settled.
- Reject active-turn recovery when durable history cannot prove
provider-turn continuity.
- Require a semantic result to belong to the latest completed terminal
settlement.
- Reject an older completed semantic result when a later identical retry
failed or was interrupted.
- Reject resultless recovery unless the latest terminal turn completed
successfully.
- Bound terminal history and semantic-result recovery by entry count,
aggregate bytes, fingerprint bytes, node count, and nesting depth before
cloning or serializing persisted data.
- Read the private workspace record through pinned namespace,
runtime-root, record, and workspace identities.
- Reject symbolic links, substituted directories, replaced records,
invalid files, root workspaces, and workspace changes during admission.
- Keep the recovery workspace lease pinned and revalidate it at the host
and provider-spawn boundaries.
- Retain and close a workspace lease that resolves after cancellation.
Close a partially recovered provider session if lease cleanup fails.
- Stage a valid isolated Codex credential in the runtime-open-boundary
regression so the test reaches and proves the intended workspace
revalidation fence.
- Add focused recovery tests for settled checkpoints, terminal
ownership, stale semantic results, active turns, identity drift, bounded
persisted data, cancellation, directory substitution, record
replacement, and spawn-boundary workspace replacement.
## Verification
- Replay base: `30ef14edd4e7290d9eac43ca7b7835611933cc74` (`master`
after #12406 merged).
- Exact replay head: `3d1b16d5cda2dd72f83785c921a025cc57aab8d6`.
- Stable patch ID for the exact replay delta:
`10742d7db00f801b5723e7a8582c637261ceb0dd`. The source-stack combined
patch was `4d7c9de72a0a30f6e33c935c092b745fe414c588`; the replay
preserves the newer unconditional provider process-group containment
from `master` while adding recovery workspace revalidation before spawn,
plus the exact-head credential fixture correction exposed by GitHub
Actions.

- Focused GitHub recovery tests: **PASS**. The exact-head Build job
passed the harness backend, native runtime, Codex ACPX driver, runtime
host, runtime sandbox, runtime adapter, and backend factory suites as
part of all 751 TypeScript runner tests.
- GitHub Actions: **PASS** for exact head
`3d1b16d5cda2dd72f83785c921a025cc57aab8d6`. Every applicable job passed.
The Storybook visual regression skipped intentionally because this
package-only delta does not touch UI or Storybook paths.

verification environment for the replayed revision.
## Risks
This change has medium package-local risk because it admits persisted
state back into a provider session. Recovery fails closed when an active
provider turn has no matching terminal fingerprint, when a semantic
result is not owned by the latest completed settlement, when any durable
identity changes, or when the workspace cannot remain pinned through
provider spawn. Recovery never selects a replacement provider session.
Bounds prevent oversized or deeply nested persisted state from consuming
unbounded work before validation. The workspace lease prevents path
substitution during recovery admission. Existing direct adapters and the
Codex app-server driver do not use this ACPX recovery route. This change
does not add a migration, dependency, lockfile update, workflow, server
route, UI surface, public export, or production rollout flag.

## Linked Issues or Issue Description
Refs #12405
This pull request builds on the Codex ACPX harness driver merged in
#12405. It adds only the package-local backend factory route for that
driver.
## What Changed
- Add an internal Codex ACPX native backend constructor.
- Require provider kind `acpx` and agent `codex` at the
provider-specific boundary.
- Resolve the qualified Codex ACPX profile for the requested model.
- Compare the persisted driver kind, protocol version, ACPX version,
agent profile, package versions, runtime package fields, and command
digest with the qualified profile.
- Compose the existing native system instructions and task constraints
for the Codex ACPX driver.
- Route qualified Codex ACPX inputs through the native backend factory
only when the caller supplies an explicit instance runtime directory.
- Pass the scoped environment, managed credential source, dynamic tools,
and ACPX tool handler through the factory boundary.
- Keep Pi, Claude, OpenCode, managed Claude, AgentCore, and every other
deferred ACPX agent unavailable.
- Add factory tests for qualified construction, the explicit
runtime-root requirement, unsupported ACPX agents, and
qualification-snapshot drift.
- Keep ACPX construction lazy. Reading the backend descriptor does not
start ACPX transport or a provider process.
## Verification

## Risks
This change has low package-local runtime risk. It adds a new branch to
the native backend factory, but no server or runnerd factory selects an
ACPX execution in this pull request. The route fails closed when the
runtime directory is absent, the agent is not Codex, or the persisted
qualification snapshot differs from the qualified Codex profile. The
constructor repeats the provider-kind and agent checks as a second
boundary. Existing direct adapters do not use this route. The change
does not add a migration, dependency, lockfile update, workflow, UI
surface, public export, or production rollout flag.

## Linked Issues or Issue Description
Refs #12404
**Subsystem affected**
This change affects `packages/paperclip-runner`, the Codex ACPX driver,
and the provider-neutral native session runtime.
**Problem or motivation**
The package has an admitted Codex ACPX session, bounded turn control,
and authenticated semantic tools. It does not have a `HarnessDriver`
implementation that joins those parts and emits canonical PRP events. It
also needs bounded ownership for provider cleanup that settles after a
caller-facing timeout. Cancellation can win after the host schedules
runtime admission and transfers the staged credential but before the
adapter body starts; that rejected admission must still prove that
provider cleanup is complete so the credential can be scrubbed and later
admission can proceed. Separately, an external close that coalesces onto
an exhausted autonomous reconciliation must not lose its cleanup intent
if that exact protocol or provider-process cleanup fails.
**Proposed solution**
Add a Codex-only harness driver. It opens the admitted host, executes
one active turn, normalizes ACPX events, dispatches run-scoped tools,
and commits one schema-valid completion or blocked result. It provides
bounded event storage, interruption, transcripts, usage, snapshots,
diagnostics, and ordered close behavior. The native session runtime
quarantines incomplete cleanup before another session can enter the same
cleanup domain. The ACPX adapter records the immutable origin and
attempt number of each exact close attempt. Autonomous reconciliation
failures stay inside the three-attempt budget of the generation that
created them. External callers that join an attempt are represented by
one idempotent batched intent: success consumes it, failure on an
earlier attempt uses the remaining same-generation retries, and failure
on the exhausted final attempt creates exactly one new bounded
generation. Both direct and late protocol/provider cleanup outcomes use
the same rule. At the adapter entry boundary, an already-aborted
admission transfers an already-complete cleanup proof before rethrowing
the exact abort reason; the host retains credential cleanup until that
proof settles.
**Alternatives considered**
The multi-provider integration driver was not copied because it mixes
deferred providers and recovery behavior into the Codex path. Direct
server registration was also deferred because this package slice must
remain inactive and independently safe. Relabeling a coalesced
autonomous attempt as external was rejected because it would let
observers replenish retry budgets; starting another protocol close
before the exact retained attempt settles was rejected because it would
overlap cleanup ownership.
**Roadmap alignment**
This is package-local production hardening for the experimental runner.
It does not enable a new adapter or change current agent execution
selection.
## What Changed
- Add a Codex-only ACPX `HarnessDriver` and session implementation.
- Advertise only implemented capabilities. Keep resume, steering,
runtime request resolution, runtime request handoff, goals, and thread
lineage unavailable.
- Emit canonical PRP turn, transcript, tool execution, final reply,
result, failure, interruption, and usage facts.
- Dispatch authorized dynamic tools through the authenticated semantic
bridge.
- Validate and commit one completion or blocked result with disposition
and conflict checks.
- Add stable bounded event identities, one-active-turn admission,
terminal capacity reservation, and bounded interruption.
- Redact authorization credentials from emitted events and retained
transcripts.
- Add read, reconcile, transcript, usage, snapshot, status,
interruption, and ordered close surfaces.
- Retain and quarantine host cleanup that outlives a caller-facing close
bound.
- Gate new native-session admission on prior cleanup in the same cleanup
domain.
- Preserve durable success and governed waits while provider cleanup
continues under bounded ownership.
- Transfer a completed cleanup proof when cancellation wins before the
Codex adapter body, then preserve the caller's exact abort reason.
- Add a host-level regression proving staged credentials are scrubbed,
the credential lease can be reacquired, and a later runtime admission
succeeds after that pre-entry abort.
- Tag each exact ACPX close attempt with an immutable external or
reconciliation origin and immutable reconciliation attempt number.
- Keep timed-out autonomous reconciliation failures inside their
originating three-attempt budget.
- Batch concurrent external callers that join one reconciliation attempt
so they cannot mint independent generations.
- Consume a joined external intent on successful cleanup and on an
earlier failed attempt that still has same-generation retries.
- Renew exactly one bounded generation when a joined external intent
reaches a failed, exhausted final reconciliation attempt.
- Treat both protocol-close and provider-process cleanup failures as
failed intent settlement, including non-timeout and timed-out late
paths.
- Prevent a coalescing external observer from relabeling an immutable
autonomous attempt.
- Reset the finite reconciliation budget only for a distinct external
late-failure generation or one failed batched intent on an exhausted
final attempt.
- Isolate persistent-cleanup tests by cleanup domain and attach expected
rejection handlers before fake timers release them.
- Stabilize cleanup-settlement assertions exposed by GitHub Actions:
observe retained proofs without relying on callback order, wait for the
credential lease release rather than only the preceding credential-file
deletion, and use a supported scalar size assertion instead of an
unavailable Set matcher.
- Add focused tests for driver behavior, event validation, bounded
buffers, cleanup quarantine, admission gating, immutable attempt
origins, final-attempt intent batching, direct and late cleanup
failures, late success consumption, bounded reconciliation, exact
pre-entry cancellation, credential recovery, and durable native-session
outcomes.

## Risks
This change has medium package-local risk. It adds a new driver and
changes native-session cleanup coordination. A lagging event consumer
could otherwise lose terminal state. The driver reserves terminal
capacity and rejects new work when bounded storage cannot safely accept
it. A stalled, rejected, or late provider close could otherwise overlap
a new session, retain credentials indefinitely, lose an external cleanup
request, or consume unlimited retries. Cleanup-proof transfer keeps the
staged credential owned across the pre-entry abort race, while the host
scrubs it only after the adapter proves that no provider resource
exists. Cleanup quarantine blocks conflicting admission and keeps exact
attempts owned. Immutable attempt origins and attempt numbers prevent
autonomous retries and coalesced observers from silently replenishing
the cap. One batched external intent can renew one generation only after
the exhausted final attempt fails; earlier failures remain within the
original generation, and success consumes the intent. Each renewed
generation remains capped at three autonomous attempts. The driver
reports recovery and other unimplemented capabilities as unavailable. No
server or runnerd factory selects this driver in this pull request.

## Linked Issues or Issue Description
Refs #12403
**Subsystem affected**
This change affects `packages/paperclip-runner` and its package-local
Codex ACPX runtime boundary.
**Problem or motivation**
The package has an authenticated semantic MCP bridge and an admitted
Codex ACPX session. The two components are not connected. A direct
connection must not persist the bridge token. It must not allow
unrelated MCP operations. The deny-all mode must remain closed for
runner-owned MCP requests.
**Proposed solution**
The runtime host starts one loopback bridge when semantic tools are
configured. It passes an ephemeral bearer binding to ACPX. The adapter
projects that binding into the ACP runtime configuration. It sends each
permission request through the existing ACPX permission policy. The
deny-all mode rejects every request. Other requests either receive the
policy result or delegate to an available coordinator.
**Alternatives considered**
Persisting MCP configuration with the ACPX session was rejected because
it would retain authentication material. A global MCP endpoint was
rejected because it would weaken run isolation.
**Roadmap alignment**
This is package-local hardening for the existing experimental runner
work. It does not enable a new user-facing adapter.
## What Changed
- Start and own one authenticated semantic MCP bridge when a host
receives semantic tool options.
- Pass one ephemeral loopback MCP binding to the Codex ACPX adapter.
- Keep the bridge token out of the persisted environment and ACPX
session options.
- Map the runner-owned HTTP MCP binding into ACPX runtime configuration
with a bearer header.
- Apply the existing ACPX permission policy to runtime permission
requests.
- Keep the deny-all mode closed for runner-owned MCP requests.
- Delegate only the permission decisions that require a coordinator.
- Revoke the tool bridge after the runtime close attempt settles,
including when runtime close fails.
- Release staged credentials only after the exact runtime close
succeeds.
- Add focused host and adapter tests for bridge dispatch, secret
isolation, fail-closed permissions, delegation, and cleanup.

## Risks
The main risk is secret or permission leakage at the ACP boundary. The
host passes the bearer token only in ephemeral runtime configuration. It
does not put the token in the persisted environment or ACPX session
options. The existing permission policy controls every ACPX permission
request. The deny-all mode rejects runner-owned MCP requests too.
Another risk is partial cleanup. The host revokes the tool bridge after
the runtime close attempt settles. It retains staged credentials if the
exact runtime close fails. This pull request stays inside the runner
package and does not select the experimental runner in the server.

## Linked Issues or Issue Description
Refs #12402
**What would you like to improve?**
The package-local ACPX host stops at session admission. A later driver
needs to submit a prompt, consume typed ACP events, wait for the
terminal result, cancel work, and close the session. Passing the full
third-party runtime through the host would bypass the existing trust and
cleanup boundary.
**Why is this important?**
Provider prompts can be large. Turn identifiers participate in durable
correlation. Concurrent turns can make replay and cancellation
ambiguous. Shutdown must also stop an active prompt before credentials
and verified command resources are released. A provider that does not
finish cancellation must not block all remaining cleanup indefinitely.
**Suggested approach**
Add a minimal turn interface to the admitted runtime port. Accept one
prompt turn at a time. Bound the request identity and text before the
runtime sees them. Map the call to ACPX prompt mode with the admitted
session handle. Track the active turn and request cancellation before
ordered runtime cleanup. Bound the cancellation wait. Continue runtime
and command cleanup after that timeout. Release staged credentials only
after the exact runtime close succeeds.
**Additional context**
This pull request builds on #12402. It does not attach semantic tools,
normalize provider events, create a harness driver, start runnerd,
register production execution, or change server, UI, or direct-adapter
behavior.
## What Changed
- Add a narrow ACPX turn input and result and event lifecycle to the
admitted runtime port.
- Map prompt turns to the exact persistent ACPX session handle.
- Support abort signals without adding steering or attachments.
- Reject empty, whitespace-normalized, or oversized request identities.
- Reject prompt text larger than one MiB before third-party code
executes.
- Permit only one active turn per host.
- Clear the active turn only after the canonical ACPX result settles.
- Reject new turns as soon as shutdown starts.
- Cancel an active turn before runtime, credential, and command cleanup.
- Bound the cancellation wait to two seconds.
- Continue runtime and command cleanup when turn cancellation fails or
reaches its timeout.
- Release staged credentials only after the exact runtime close
succeeds.
- Keep the cancellation handle and credential lease when runtime cleanup
remains retryable.
- Coalesce concurrent close calls and report all cleanup failures in one
aggregate error.
- Add focused host and adapter tests for turn mapping, bounds,
concurrency, cancellation, timeout cleanup, credential retention, and
late-turn rejection.

## Risks
The primary risk is ambiguous concurrent execution. The host admits only
one active turn and releases that slot from the canonical ACPX terminal
result. Another risk is partial shutdown. The host requests cancellation
first and waits for at most two seconds. It then attempts runtime and
command cleanup even if cancellation fails or reaches the timeout. It
releases staged credentials only after the exact runtime close succeeds.
If runtime cleanup fails, the host keeps the cancellation handle and
credentials for a later cleanup attempt. This pull request does not
register the runtime for production use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native providers can receive only the semantic operations authorized
for one run.
> - Codex ACP consumes those operations through an MCP endpoint.
> - The endpoint must be private, authenticated, bounded, and
deterministic under retries.
> - It must not advertise runner-private operations or allow callers to
replace terminal-result schemas.
> - This pull request adds a provider-neutral loopback MCP bridge with
those controls.
## Linked Issues or Issue Description
**What would you like to improve?**
The runner has a run-scoped semantic catalog and dispatcher, but the
ACPX runtime needs a secure transport for that catalog. A generic local
MCP server could expose extra operations, accept ambiguous tool
definitions, or execute the same call twice after a retry.
**Why is this important?**
Semantic tool presence is part of the authorization boundary.
Undiscoverable operations must remain unavailable. Terminal completion
and blocked-result schemas must not be replaceable. Duplicate call
identities must be idempotent, and conflicting duplicates must fail
closed.
**Suggested approach**
Bind one MCP endpoint to `127.0.0.1` for each admitted runtime. Require
a random bearer secret. Compile the closed tool schemas before
listening. Keep private operations out of `tools/list`. Validate and
fingerprint each call before dispatch. Bound request size, result size,
time, and retained call identities. Abort active operations on timeout,
cancellation, or bridge close.
**Additional context**
#12401 is merged. This PR does not attach the bridge to ACPX, register a
provider, or change any server or direct-adapter behavior.
## What Changed
- Add a provider-neutral runner semantic MCP bridge bound only to IPv4
loopback.
- Require constant-time bearer authentication before MCP operations.
- Expose only the supplied public catalog plus fixed completion and
blocked-result tools.
- Keep runner-private operations callable by trusted extensions but
absent from discovery.
- Reject invalid names, duplicate definitions, public/private
collisions, and terminal schema replacement.
- Compile JSON Schema validators before accepting traffic.
- Validate calls before dispatch and replay identical duplicate
identities exactly once.
- Treat numeric and string JSON-RPC identities as distinct and reject
conflicting duplicates.
- Bound request bodies, result text, timeouts, retained identities, and
concurrent capacity.
- Terminate oversized request bodies, preserve successful mutation
outcomes, and keep complete semantic results.
- Propagate MCP cancellation and abort active calls during close.

behavior.
- No additional local suite was run during the final restack; GitHub

## Risks
The main risk is widening model-visible authority. The bridge exposes
only its closed public catalog and fixed terminal tools; private
operations are omitted from discovery and catalog ambiguity fails during
startup. Another risk is duplicate execution after a provider retry. The
bridge fingerprints each admitted JSON-RPC identity, reuses the first
promise for exact retries, and rejects changed payloads. The endpoint
uses loopback plus a per-runtime bearer secret and has no production
caller in this pull request.

## Linked Issues or Issue Description
**Agent or provider**
Codex through the exact ACPX and Codex ACP packages landed in #12400.
**Why this adapter is useful**
The package-local runtime host has an injected port, but no production
implementation. This implementation uses the verified executable lease
and private runtime sandbox without persisting managed credentials or
other launch-only state in ACPX recovery records.
**How the agent is invoked**
The adapter creates one persistent ACPX Codex session. ACPX receives a
placeholder registry command, while its patched spawn callback launches
through Paperclip's verified command lease. The private launch
environment is supplied only at spawn time. Durable session state
receives only the session key, workspace, model, and bounded system
instructions.
**Additional context**
#12400 is merged. This PR does not register an adapter, start runnerd,
expose a server route, or change any direct adapter. It supports Codex
only, rejects non-Codex profiles, and fails closed on Windows until
provider descendants can be contained with an owned Job Object or
equivalent.
## What Changed
- Add a Codex-only adapter from the pinned ACPX library to the admitted
runtime port.
- Create the ACPX store inside the private runtime state directory.
- Open one persistent session with the qualified model and bounded
system instructions.
- Route provider launches through the verified executable lease and a
dedicated POSIX process group.
- Retain cleanup ownership through asynchronous errors and late
termination.
- Supply the private launch environment at spawn time without persisting
it.
- Require all ACPX recovery identity fields before returning the runtime
port.
- Map status, exact model selection, and state-preserving close
operations.
- Add regression coverage for secret isolation, verified spawning,
process-tree cleanup, lifecycle mapping, identity failure, and the
Codex-only boundary.
## Verification

workflows, migrations, server selection, or UI behavior.
- No additional local suite was run during the final restack; GitHub
Actions is the authoritative verification environment.
## Risks
The primary risk is leaking launch credentials into durable ACPX state.
Session options are constructed explicitly and regression-tested; the
launch environment remains behind the spawn-time callback. Another risk
is orphaning credential-bearing descendants. Supported launches use a
retained POSIX process-group identity with bounded TERM-to-KILL cleanup.
Windows fails closed before runtime construction until equivalent
process-tree containment exists.

## Linked Issues or Issue Description
**Agent or provider**
Codex through `acpx@0.13.1` and `@agentclientprotocol/codex-acp@1.6.2`.
**Why this adapter is useful**
The injected runtime host needs a concrete ACP session manager and the
exact reviewed Codex ACP server. Upstream ACPX does not yet expose a
host-owned spawn callback, and upstream Codex ACP does not yet apply
Paperclip's isolated instruction, MCP, app, memory, and skill boundary.
Both behaviors are required before the dependency can execute inside the
runner.
**How the agent is invoked**
The next pull request will adapt these pinned packages to the private
runtime host. ACPX receives a host-owned callback that consumes the
already verified executable lease. Codex receives only the isolated
environment, explicit base instructions, explicit MCP servers, and the
skills rooted in its private `CODEX_HOME`. This pull request alone does
not spawn either package or register an adapter.
**Additional context**
This pull request is stacked on #12399. It adds no Pi, Claude, AWS, SDK,
lab, browser, or UI dependency. It intentionally does not commit
`pnpm-lock.yaml`: the repository policy job regenerates a manifest-only
PR lockfile artifact for downstream frozen installs, and the lockfile
bot updates master separately.
## What Changed
- Pin `acpx` to `0.13.1` and the Codex ACP server to `1.6.2` in the
runner package.
- Register both patches in the pnpm 9 root configuration and newer-pnpm
workspace configuration.
- Preserve the existing embedded-Postgres and ACPX 0.12 patch entries
used by other packages.
- Patch ACPX to evaluate an allowlisted environment at child-spawn time
and keep spawn cwd out of provider-visible session identity.
- Patch ACPX to accept a host-owned spawn callback with the resolved
arguments and options, allowing the verified command lease to own
execution.
- Patch Codex ACP to retain runner-owned MCP server identity in
permission requests.
- Patch Codex ACP to pass explicit Paperclip base instructions on both
start and resume.
- In isolated mode, disable ambient apps, memory, and existing MCP
configuration; load skills only from `CODEX_HOME`; and configure only
requested servers.
- Add a package contract test that enforces exact versions, Codex-only
dependency scope, both pnpm patch registries, and every required patch
hook.
## Verification
- Both patch files dry-apply successfully to fresh published tarballs
for `acpx@0.13.1` and `@agentclientprotocol/codex-acp@1.6.2`.
- A local no-lockfile install applied both patches; their runtime
markers and exact installed versions were inspected.
- Runner TypeScript typecheck — passed against the patched packages.
- Runner package tests — passed: 16 Node protocol/package tests and 426
Vitest tests.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- `git diff --check` — passed.
- The diff contains 6 files and does not change `pnpm-lock.yaml`, a
GitHub workflow, server selection, or UI behavior.
## Risks
The primary risk is drift between published package contents and
checked-in compiled patches. Exact versions are pinned, both patches are
exercised by package-contract gates, and CI performs the authoritative
regenerated-lockfile frozen install. The spawn callback does not grant a
new executable path: the following adapter must consume the opaque
verified command lease. Codex isolation changes activate only when
`PAPERCLIP_ACPX_ISOLATED_CONTEXT=1`, so existing direct Codex adapters
are unaffected.

## Linked Issues or Issue Description
**Agent or provider**
The qualified Pi, Claude, and Codex ACPX profiles; Codex additionally
uses the managed credential lease.
**Why this adapter is useful**
The runner needs one owner for startup ordering, immutable identity
checks, exact model verification, and cleanup. Otherwise a failure after
credential staging or command admission can leave secret files or
executable leases alive, and a resumed provider can attach to a
different profile, workspace, model, or permission mode.
**How the agent is invoked**
A later dependency-adapter pull request will implement the injected
runtime port with the pinned ACPX library. This host passes that adapter
an opaque verified command lease, canonical workspace, private state
directory, profile-bound session key, qualified permission policy,
launch-only environment, and bounded instructions. It does not expose
the runtime directly or add a user-selectable adapter.
**Additional context**
This pull request is stacked on #12398. Installation verification has a
production default; only the third-party runtime opener is injected.
Tests use a fake port so this boundary remains package-local and
dependency-free.
## What Changed
- Add a minimal ACP runtime port for identity, status, model selection,
and bounded shutdown.
- Derive the qualified profile and canonical recovery binding before any
provider startup.
- Reject expected-identity drift and irrelevant managed-Codex inputs
before opening the provider.
- Verify that even an injected installation result matches the closed
profile digest.
- Prepare the private sandbox and stage Codex credentials only for the
Codex profile.
- Acquire an opaque verified command lease and pass only the composed
launch boundary to the runtime port.
- Apply the canonical permission policy and collision-resistant provider
session key.
- Select and verify the exact effective model before returning an
admitted host.
- Create a strict versioned identity record and compare resumed provider
identifiers with the expected record.
- Keep the runtime private and expose only cloned identity, binding,
runtime-root, and persistence-safe environment views.
- On startup or shutdown failure, attempt runtime close, credential
cleanup, and command-lease cleanup in order and aggregate every error.
- Add tests for Codex secret isolation, Claude selector verification,
recovery drift, injected digest drift, partial-start cleanup, and
cleanup retry.
## Verification
- Runner TypeScript typecheck — passed.
- Runner protocol and TypeScript tests — passed: 12 protocol tests and
426 Vitest tests, including 6 runtime-host tests.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 2 files and does not change `pnpm-lock.yaml`, a
workflow, a dependency, a public package export, server selection, or UI
behavior.
## Risks
The main risk is leaking a partially admitted resource when a later
admission step fails. Resource acquisition is linear and all failure
paths use the same ordered cleanup routine. The runtime port is
deliberately minimal and privately owned by the host; it cannot bypass
profile, model, recovery, sandbox, credential, or command admission. The
actual ACPX implementation and its process-supervision behavior remain a
separate review unit.

## Linked Issues or Issue Description
**Agent or provider**
The qualified Codex ACPX profile.
**Why this adapter is useful**
Managed installations may already have a Codex login document, while
service deployments may provide an API key or inline JSON. The runner
needs all three modes without copying ambient home state, accepting
ambiguous sources, persisting secret values in ordinary runner state,
following links, or allowing concurrent processes to mutate the same
credential home.
**How the agent is invoked**
A later runtime-host pull request acquires this credential lease before
opening Codex and closes it during shutdown and failed-start paths. API
keys remain launch-only environment values. JSON credentials are
atomically staged as `auth.json` inside the isolated Codex home. This
pull request does not spawn Codex, add a dependency, register an
adapter, or change execution selection.
**Additional context**
This is the lowest unmerged PR in the runner series and targets `master`
directly. It deliberately requires one explicit credential source and
never reads the Paperclip server user's ambient home by default.
## What Changed
- Add one-use managed Codex credential leases for API-key, inline-JSON,
and explicit managed-file modes.
- Reject missing and ambiguous source combinations.
- Require absolute external managed-file paths, private ownership and
permissions on POSIX, bounded documents, no-follow opens, and stable
file identity during reads.
- Stage JSON through a deterministic private no-follow staging path,
scrub stale staging state on admission, sync the file, rename
atomically, and sync the parent directory.
- Persist a bounded cleanup intent and remove staged or
provider-generated authentication files without following links.
- Fence each canonical credential home with a markerless 2-of-3
exclusive loopback quorum derived from the current UID and canonical
home. One unrelated occupied candidate is tolerated; two occupied
candidates fail closed before credential mutation.
- Bound stuck parent filesystem operations and cleanup helpers
process-wide so an unresponsive filesystem cannot create unbounded work.
- Zero temporary credential buffers and make cleanup retryable without
allowing a stale cleanup generation to affect a successor.
- Add focused tests for credential modes, permissions, malformed and
ambiguous sources, symlink rejection, deterministic staging, quorum
contention and crash release, stuck-operation bounds, and idempotent
cleanup.
## Verification
- Prettier and `git diff --check` passed for the exact pushed head.
- Greptile reviewed the exact head at 5/5 with no blocking finding;
independent static audits found no remaining correctness, security,
test-contract, or resource-bound blocker.
- GitHub Actions passed on the exact head
`29e75afb7b8529b9d070070e0c1462e795d115bb`, including Build, Typecheck,
the complete test matrix, e2e, verify, and security checks. One
unrelated hosted-runner `npm ENOENT` shard passed on its GitHub rerun.
- The diff contains 2 files and does not change `pnpm-lock.yaml`,
workflows, dependencies, public package exports, server selection, or UI
behavior.
## Risks
The primary risks are credential disclosure, concurrent ownership, and
cleanup that outlives its authority. Secret values never enter returned
identity or durable runner data. Source and destination operations are
bounded, no-follow, privately permissioned, and crash-durable. The
markerless kernel quorum prevents concurrent home mutation without
trusting a replaceable marker, while process-global operation/helper
caps prevent unresponsive filesystem work from growing without bound.
Cleanup is generation-scoped so a stale retry cannot remove a
successor's credential.

## Linked Issues or Issue Description
**Agent or provider**
The qualified Pi, Claude, and Codex ACPX profiles.
**Why this adapter is useful**
Each agent expects different home and configuration variables, but none
should inherit the Paperclip server user's general home, provider
credentials for another agent, or unrelated process secrets. Runtime
recovery also needs stable non-secret paths without persisting API keys,
OAuth tokens, proxy credentials, or MCP bootstrap tickets.
**How the agent is invoked**
A later runtime-host pull request will prepare this sandbox, then pass
its frozen launch environment and private directories to a verified ACPX
command lease. This pull request does not spawn an agent, add
dependencies, register an adapter, or alter server execution selection.
**Additional context**
This pull request is stacked on #12395. It uses that pull request's
canonical workspace and collision-resistant runtime binding. All
filesystem and environment behavior remains package-local.
## What Changed
- Create a normalized session root beneath the private `acpx` runtime
namespace.
- Create isolated home, configuration, data, cache, state, and
agent-specific directories with mode `0700`.
- Reject symbolic links, non-directory paths, namespace escapes, and
non-normalized roots.
- Write the canonical workspace record and Pi trust settings atomically
through exclusive no-follow temporary files with mode `0600`.
- Give Pi, Claude, and Codex only their qualified home and isolation
variables.
- Reuse the existing per-agent environment allowlist for launch-time
credentials and bound the final environment size.
- Return a separate persistence-safe environment containing only stable
paths, locale values, and non-secret agent flags.
- Explicitly exclude provider credentials, proxy URLs, MCP URLs, and MCP
tokens from the persisted projection.
- Add table-driven tests for all three agents, file modes, state
contents, secret splitting, idempotence, and symbolic-link rejection.
## Verification
- Runner TypeScript typecheck — passed.
- Runner protocol and TypeScript tests — passed: 12 protocol tests and
413 Vitest tests, including 5 runtime-sandbox tests.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 2 files and does not change `pnpm-lock.yaml`, a
workflow, a dependency, a public package export, server selection, or UI
behavior.
## Risks
The main risks are following attacker-controlled filesystem aliases or
persisting a credential under an unexpected variable name. Every created
path is checked against its physical parent, the session root must
already be absolute and normalized, temporary files use exclusive
no-follow opens, and the persisted projection is a positive allowlist
rather than a credential-name blacklist. The launch environment remains
available only in memory and is bounded before use.

## Linked Issues or Issue Description
**Agent or provider**
Durable sessions for qualified Pi, Claude, and Codex ACP servers through
the internal ACPX driver.
**Why this adapter is useful**
The runner must prevent a persisted provider session from being reused
with another workspace, model, permission policy, profile, or normalized
session. It must also distinguish normalized session names that sanitize
to the same pathname.
**How the agent is invoked**
A later pull request will use this binding when the private ACPX runtime
opens or recovers a session. This pull request does not launch a
process, add a dependency, register an adapter, or change runtime
selection.
**Compatibility boundary**
No ACPX identity writer exists on master or in a shipped runtime. This
pull request establishes the first accepted persisted format. Draft
schema-less records and early-v1 command-digest records cannot prove
every immutable binding and are intentionally rejected; an affected
experimental session must start fresh.
## What Changed
- Resolve real workspace and runtime-directory paths and reject
filesystem roots or non-directories.
- Derive collision-resistant runtime roots and provider session keys.
- Bind the session key to workspace, complete qualified profile, model,
protocol, agent, and permission mode.
- Add a closed v1 ACPX identity record.
- Verify controller identity and persisted identity against every
immutable binding.
- Reject schema-less, early-digest, unknown-version, unknown-field, and
malformed records.
- Add tests for canonical paths, collision resistance, drift,
workspace/session replay, missing policy, malformed records, and unsafe
roots.
## Verification
- GitHub Actions are the authoritative typecheck, test, build, and
integration gate for the final head.
- Greptile, Superagent, and Snyk are required to pass on the final head.
- `git diff --check` passes for the two-file delta.
- The diff does not change `pnpm-lock.yaml`, a workflow, a dependency, a
public export, server selection, migration, or UI behavior.
## Risks
The main risk is accepting an identity under a different immutable
session configuration. Controller and v1 record fields are compared
exactly, including permission mode and the complete qualified-profile
digest. Records that lack workspace/session provenance or use an
obsolete partial digest fail closed. Because no writer for those draft
formats has shipped, requiring a fresh experimental session is safer
than synthesizing missing authority from the current request.

## Linked Issues or Issue Description
**Agent or provider**
Internal qualified ACPX profiles. The first production consumer remains
Codex-only in the follow-on dependency and adapter changes.
**Why this adapter is useful**
The runner needs to prove that installed package metadata and executable
bytes match a reviewed profile, then prevent pathname replacement,
symlink escape, host-package lookup, or loader injection from changing
what executes.
**How the agent is invoked**
A later provider-specific adapter requests an opaque one-use command
lease. On Linux, the lease starts Node with a synchronous hook, supplies
the verified entry snapshot over a private pipe, and retains only the
verified package directories needed by that profile. This pull request
does not register an adapter, change runtime selection, or make any
provider user-visible.
**Compatibility boundary**
The launched entry deliberately has a Linux descriptor-backed identity
such as `/proc/self/fd/4/...`; preserving a mutable canonical pathname
would reopen the replacement vulnerability. A provider that requires
canonical `import.meta.url`, `__filename`, or `process.argv[1]` is not
admitted by this primitive until its provider-specific adapter proves
compatibility. Likewise, arbitrary package-manager ancestors are not
retained. Hoisted dependencies must be explicitly qualified by a later
provider-specific layer; otherwise startup fails closed. The initial
production slice is Codex only, not Pi or Claude.
## What Changed
- Verify exact server and optional runtime package versions from bounded
metadata.
- Require one supported relative Node executable and reject ambiguous or
package-escaping paths.
- Canonicalize the command directory and open final components without
following symbolic links.
- Bound and hash the open entry file while checking device, inode, size,
and timestamps around the read.
- Return an opaque installation and one-use launch lease instead of an
executable pathname.
- Reopen and revalidate retained directory and executable identities
when acquiring a lease.
- Load the admitted entry bytes and package-contained modules through
retained Linux descriptors.
- Resolve CommonJS and ESM bare imports only from retained roots, reject
host ancestors, and make symlink escape terminal.
- Open module bytes with `O_NOFOLLOW`, bound each read, recheck
identity, and reject native or unsupported module formats.
- Strip Node, native dynamic-loader, glibc, and OpenSSL injection
variables before spawn.
- Add regressions for replacement races, direct resources, sibling and
ancestor imports, explicit runtime roots, host-ancestor denial,
descendant and final symlinks, bounded reads, and environment injection.
## Verification
- The authoritative GitHub Actions and exact-head Greptile review are
the merge gates for the final head.
- Prettier and `git diff --check` pass for the final two-file diff.
- The diff does not change `pnpm-lock.yaml`, workflows, dependencies,
public exports, server selection, or UI behavior.
## Risks
The security/compatibility tradeoff is explicit: descriptor identity
prevents a replaced lexical path from supplying resources, but
pathname-sensitive providers require a later adapter-specific
qualification. Unqualified or unsupported dependencies, native addons,
non-Linux launch, and unsupported module formats fail closed. No
production call path reaches this primitive in this pull request.

## Linked Issues or Issue Description
**Agent or provider**
Qualified Pi, Claude, and Codex ACP servers through the internal ACPX
driver.
**Why this adapter is useful**
The runner must not assume that an ACP session uses the requested model.
It needs a status check, an exact model selection when required, and a
second status check before work can begin.
**How the agent is invoked**
A later pull request will provide the private ACP runtime control behind
this interface. This pull request does not launch a process, add a
dependency, register an adapter, or change runtime selection.
**Additional context**
This pull request is stacked on #12391. Claude's qualified canonical
model is `claude-sonnet-5`, while its pinned ACP server reports the
stable selector `sonnet`.
## What Changed
- Require ACP model status before accepting a qualified runtime.
- Select the exact canonical model when the session reports a stale
default.
- Reapply canonical selection when a qualified profile uses a distinct
ACP selector.
- Fail closed when status, model selection, or the expected reported
selector is unavailable.
- Normalize a verified selector back to the canonical model for
provider-neutral status consumers.
- Add tests for exact, stale, aliased, unavailable, and
ignored-selection cases.
## Verification
- Runner TypeScript typecheck — passed.
- Runner TypeScript tests — passed, including 5 new model-verification
tests.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 2 files and does not change `pnpm-lock.yaml`, a
workflow, a dependency, a public export, server selection, or UI
behavior.
## Risks
The main risk is treating a provider alias as proof of the requested
model. A distinct selector is accepted only when it is part of the
immutable qualified profile, after the runner sends the exact canonical
model through ACP and performs a second status check. All other
mismatches fail closed.

## Linked Issues or Issue Description
**Agent or provider**
Qualified Pi, Claude, and Codex ACP servers through the internal ACPX
driver.
**Why this adapter is useful**
ACP providers use permission requests for both ordinary provider
operations and runner-owned semantic operations. Paperclip must apply
`approve-all`, `approve-reads`, or `deny-all` consistently while keeping
semantic authorization bound to structural MCP metadata.
**How the agent is invoked**
A later pull request will install this policy in the private ACPX
runtime host. This pull request does not launch a provider, add a
dependency, register an adapter, or change runtime selection.
**Additional context**
This pull request is stacked on #12390. Pi uses a different bridge and
never receives semantic auto-approval through this ACP permission path.
## What Changed
- Map each ACPX permission mode to a closed runtime policy.
- Decide local allow, reject, or coordinator delegation outcomes.
- Auto-approve only runner-owned semantic MCP calls identified by
structural metadata.
- Ignore provider display titles when determining semantic authority.
- Limit Codex blanket MCP approval to sessions where every configured
MCP server is runner-owned.
- Add table-driven tests for all modes, agents, metadata shapes, spoofed
titles, and non-runner servers.
## Verification
- Runner TypeScript typecheck — passed.
- Runner TypeScript tests — passed, including 10 new permission-policy
assertions.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and

- Prettier and `git diff --check` — passed.
- The diff contains 2 files and does not change `pnpm-lock.yaml`, a
workflow, a dependency, a public export, server selection, or UI
behavior.
## Risks
The main risk is mistaking a provider-controlled label for an authorized
semantic tool. The implementation ignores display titles and requires a
runner-owned MCP server name, a transport tool name, or provider
metadata. All other `approve-reads` mutations delegate to the
coordinator, and the caller must reject them when no delegate exists.

## Linked Issues or Issue Description
**Agent or provider**
Qualified Pi, Claude, and Codex ACP servers through the internal ACPX
driver.
**Why this adapter is useful**
The runner needs a truthful capability descriptor and a closed
configuration boundary before it can create an ACPX session. The
boundary must reject arbitrary commands and unqualified models.
**How the agent is invoked**
A later pull request will implement the private runtime behind this
descriptor. This pull request does not launch a process, add a
dependency, register an adapter, or make ACPX selectable.
**Additional context**
This pull request is stacked on #12389. Pi reports plan events as
unsupported. Claude and Codex report structured plan support.
## What Changed
- Add the ACPX driver descriptor and native runtime-context capability
declaration.
- Add an agent-specific typed event capability matrix.
- Add strict config validation for agent, exact qualified model, and
permission mode.
- Default the permission mode to `approve-all` when the field is absent.
- Reject non-object config, unknown fields, unqualified models, and
unsupported permission values.
- Add table-driven tests for all qualified agents and failure cases.
## Verification
- Runner TypeScript typecheck — passed.
- Runner TypeScript tests — passed, including 8 new driver-profile
assertions.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 2 files and does not change `pnpm-lock.yaml`, a
workflow, a dependency, a public export, server selection, or UI
behavior.
## Risks
The main risk is advertising a capability that a qualified ACP server
cannot supply. The matrix is explicit per agent, and tests cover the one
current difference. Config validation rejects unknown fields so a caller
cannot smuggle an executable or an unsupported runtime setting into this
boundary.

## Linked Issues or Issue Description
**Agent or provider**
The internal ACPX sidecar for qualified ACP-compatible providers.
**Why this adapter is useful**
The sidecar must process input frames in order. It must drain accepted
input before shutdown, continue after an ordinary command error, and
reject dependent commands after initialization or session bootstrap
fails.
**How the agent is invoked**
A later pull request will connect this helper to a private sidecar
process. This pull request adds no executable, dependency, adapter
registration, or process launch.
**Additional context**
This pull request is stacked on #12388. The helper remains package-local
and does not affect direct adapters.
## What Changed
- Add a serial asynchronous input queue that remains usable after
operation and diagnostic failures.
- Add ACPX-specific input sequencing around the shared queue.
- Preserve the first `initialize` or `session.open` failure as the
bootstrap cause.
- Produce a deterministic blocked-command error after bootstrap fails.
- Test ordering, EOF-style draining, error isolation, sticky bootstrap
failure, and non-sticky turn failure.
## Verification
- Runner TypeScript typecheck — passed.
- Runner TypeScript tests — passed, including 4 new sequencing tests.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 3 files and does not change `pnpm-lock.yaml`, a
workflow, a dependency, a public export, server selection, or UI
behavior.
## Risks
The main risk is allowing one failed input operation to reorder or
suppress later input. Each operation runs only after the previous
promise settles. Both operation and diagnostic failures are contained.
Bootstrap failure is recorded separately so an ordinary turn failure
does not disable the sidecar session.

## Linked Issues or Issue Description
**Agent or provider**
ACP-compatible providers that use form elicitation.
**Why this adapter is useful**
ACP providers need structured user answers during a turn. Paperclip must
present those questions through its provider-neutral contract so the
existing task experience and validation rules remain consistent.
**How the agent is invoked**
A later pull request will connect this internal adapter to the ACPX
sidecar. This pull request only implements the conversion boundary. It
does not launch ACPX, add a dependency, or enable an adapter.
**Additional context**
This pull request is stacked on #12387. URL elicitation remains
unsupported and returns no form projection.
## What Changed
- Convert bounded ACP string, enum, multi-select, Boolean, number, and
integer fields to `paperclip.question_set.v1`.
- Validate every answer with the existing provider-neutral response
parser before conversion.
- Convert validated answers back to typed ACP form content.
- Bound provider-controlled field and option inventories.
- Use stable question identities and define arbitrary property names
without prototype mutation.
- Keep ACP runtime types and dependencies outside this package-local
conversion boundary.

workflow, a package dependency, a public export, server selection, or UI
behavior.
## Risks
The main risk is accepting an ACP form that cannot be represented safely
by the Paperclip question contract. Unsupported field types fail closed.
Field and option inventories are bounded. The existing question parser
validates all text, selection, numeric, and required-field constraints
before any response returns to ACP.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The Paperclip runner needs a safe boundary before it can launch
ACP-compatible agents.

## Linked Issues or Issue Description
**Agent or provider**
ACPX sidecar support for the qualified Pi, Claude, and Codex ACP
servers.
**Why this adapter is useful**
The runner needs one bounded process boundary for ACP-compatible
providers. A closed profile prevents an untrusted run from selecting an
arbitrary executable, package version, or model.
**How the agent is invoked**
A later pull request will launch an internal sidecar from an exact
profile. This pull request only validates profiles, environment values,
and protocol frames. It does not add an executable dependency or enable
an adapter.
**Additional context**
This pull request is stacked on #12386. It keeps the existing direct
adapters and the Codex runner path unchanged.
## What Changed
- Add a closed profile table for the qualified Pi, Claude, and Codex ACP
servers.
- Require the exact qualified model and return an isolated profile value
to callers.
- Add an agent-specific environment allowlist with entry and aggregate
size limits.
- Add strict parsing for bounded sidecar requests and structured plan
values.
- Reject unknown fields, unsupported protocol versions, invalid
identifiers, null bytes, cyclic values, and oversized input.
## Verification
- Runner TypeScript typecheck — passed.
- Runner TypeScript tests — 40 files and 362 Vitest tests passed; 11
Node contract tests passed.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 6 files and does not change `pnpm-lock.yaml`, a
workflow, a package dependency, or a public export.
## Risks
The main risk is accepting more launch state than the sidecar needs. The
implementation uses an agent-specific allowlist, rejects null bytes, and
enforces per-entry and aggregate bounds. This pull request does not
launch a process or expose a new adapter, so production and
direct-adapter behavior remain unchanged.

TypeScript and Rust.

## Linked Issues or Issue Description
This is the first package-local unit in the post-Codex provider series.
**What happened?**
The integration branch contains an ACPX provider, but its TypeScript
sidecar and Rust client need a small shared authority before either
implementation can be reviewed safely. Importing the final integration
implementation directly would mix the protocol, runtime, third-party
dependencies, and production wiring.
**Expected behavior**
The schema defines every ACPX sidecar request, response, event, command,
event type, and protocol version. Generated TypeScript and Rust
inventories must drift-check against that schema. No runtime can select
or execute ACPX yet.
**Steps to reproduce**
1. Change the protocol version, command inventory, or event inventory in
the schema.
2. Run the runner protocol type check without regenerating the language
inventories.
3. Observe the drift gate fail.
**Paperclip version or commit**
Stacked on `runner-server-semantic-codex` at `ebd7f9df7`.
## What Changed
- Add the internal ACPX sidecar v2 JSON Schema outside the public PRP v1
schema catalog.
- Generate one TypeScript inventory and one Rust inventory from that
schema.
- Add generate and check hooks to the existing runner protocol-type
workflow.
- Add fail-closed AJV tests for all three message families, version
drift, unknown commands, and extra properties.
- Keep the generated Rust module unregistered until the Rust ACPX
transport exists.
## Compatibility Boundary
- Codex remains the only production runner provider.
- `paperclip_runner` selection and the default-off rollout flag are
unchanged.
- No ACPX package, patch, lockfile, binary entry point, root export,
server file, UI file, workflow, or dependency is added.
- The schema is shipped with the existing `protocol` directory but is
not added to the public PRP manifest.
- Existing direct adapters continue through their current paths.
- Diff against the actual stacked base: 6 files.
## Verification
- Runner TypeScript typecheck and both generated-contract drift gates —
passed.
- Runner TypeScript tests — 37 files and 355 Vitest tests passed; 11
Node contract tests passed.
- Rust provider-bridge regression suite after restacking — 14/14 passed.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- `pnpm test:run` — attempted; the local host reproduced unrelated
workspace/Postgres and port-exposure failures in unchanged server
suites. The changed runner contract suites pass, and the repository's
serialized/sharded GitHub checks remain authoritative for those
host-sensitive suites.
- Prettier, rustfmt, generated-source drift checks, and `git diff
--check` — passed.
- `pnpm-lock.yaml` is unchanged.
## Risks
The main risk is allowing schema and generated language inventories to
diverge. Build and typecheck now fail on any drift. The sidecar
implementation and third-party ACPX packages are deliberately absent, so
this PR cannot alter runtime behavior or expand the production attack
surface.

work.

## Linked Issues or Issue Description
Refs #12384
**What existing behavior does this improve?**
This improves the existing flagged Paperclip Runner Codex path.
**Current behavior**
The server creates a run-scoped list of authorized read tools. It does
not pass that list to runnerd, so the production Codex session starts
with no tools.
**Proposed behavior**
The server maps the authorized definitions to the versioned runner
contract. It computes a cross-language catalog digest. It includes that
immutable contract in `run.prepare`.
**Reason and benefit**
Runnerd and the server now enforce the same catalog identity. Unknown,
duplicate, changed, or malformed tool contracts fail before Codex can
use them.
**Breaking changes**
None. Direct adapters are unchanged. A native run with an empty server
projection still starts with no dynamic tools.
## What Changed
- Add a deterministic semantic-definition to runner-authorization
projection.
- Match the Rust canonical digest with a shared test vector.
- Include the server coordinator projection in the native Codex
`run.prepare` command.
- Extend the native Codex vertical slice to require and execute a
semantic tool.
- Verify the production prepare payload in a host-independent server
test.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript` (354
tests pass)
- `pnpm --filter @paperclipai/server exec vitest run
src/services/native-runtime/native-codex-runner.test.ts`
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm -r typecheck`
- `pnpm build`
- The embedded-Postgres vertical slice is present for CI. This local
host reports that embedded Postgres is unavailable, so Vitest skips that
host-dependent test locally.
- Confirmed that the PR changes 7 files against
`runner-codex-durable-tools`.
- Confirmed that `pnpm-lock.yaml` is unchanged.
## Risks
The main risk is a catalog digest mismatch between TypeScript and Rust.
Both implementations use canonical JSON. They share the same fixed
digest vector. Runnerd also recomputes the digest and rejects a
mismatch.
The rollout flag and the existing native runtime selection rules remain
unchanged.

catalog.

## Linked Issues or Issue Description
Refs #12382
**What existing behavior does this improve?**
This improves the durable Codex provider backend in
`@paperclipai/paperclip-runner`.
**Current behavior**
The Codex transport can project authorized dynamic tools. The durable
backend rejects their calls because it cannot persist and recover their
identities.
**Proposed behavior**
The durable backend records each authorized call before it emits the
semantic input event. It records each result before it sends the result
to Codex. It reconciles exact provider replays without another Paperclip
action.
**Reason and benefit**
This order prevents duplicate semantic actions after a process restart.
It also keeps unauthorized, changed, oversized, and late calls closed.
**Breaking changes**
None. A run without an authorized tool catalog still starts Codex with
no dynamic tools.
## What Changed
- Persist the authorized tool catalog with the Codex provider state.
- Emit correlated and redacted semantic input, reconciliation, and
result events.
- Reconcile exact pending and completed calls after a provider restart.
- Reject catalog drift, changed replay input, malformed results, and
unauthorized operations.
- Complete pending tool calls with a durable failure when a turn stops.
- Bound retained tool values and validate recovered state before
provider startup.
- Bind production runner events to the active run, session, turn, and
item identities.
## Verification
- `cargo fmt --all -- --check`
- `cargo test --workspace`
- `pnpm -r typecheck`
- `pnpm build`
- Confirmed that the PR changes 9 files against
`runner-codex-dynamic-tools`.
- Confirmed that dependency installation did not change
`pnpm-lock.yaml`.
## Risks
The main risk is a mismatch between recovered provider state and the
controller tool catalog. Recovery validates the complete catalog and its
digest before Codex starts. The backend persists a call before it emits
work and persists a result before it returns the result to Codex.
This PR does not enable the server adapter or change any direct adapter
path.

tool authority.

tool catalog.

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` and its Rust Codex app-server provider.
**Problem or motivation**
The native runner has a validated semantic tool catalog, but the Rust
Codex provider cannot project that catalog or correlate Codex tool calls
with Paperclip results. A resumed Codex thread also needs the same
run-scoped catalog.
**Proposed solution**
Add an explicit Codex start path that accepts validated tools. Send
those tools through `dynamicTools` for both thread start and thread
resume. Validate thread, turn, call, operation, result identity, and
size before data crosses the provider boundary.
**Roadmap alignment**
This work supports the shipped governed MCP Tool Gateway and
self-healing run milestones. It does not add a user-facing adapter or
enable the experimental runner.
## What Changed
- Add a Codex dynamic-tool projection for explicit authorized tool sets.
- Advertise the same tool set on new and resumed provider threads.
- Correlate bounded Codex tool calls and Paperclip semantic results.
- Reject calls outside the active thread or turn, unadvertised tools,
reused request identities, mismatched results, and oversized values.
- Keep the current durable backend on the zero-tool path until the next
wiring change.
- Extend the fake Codex app server and integration tests for success,
recovery, denial, and correlation behavior.
## Verification
- `cargo test --manifest-path
packages/paperclip-runner/runner/Cargo.toml --workspace`
- `cargo clippy --manifest-path
packages/paperclip-runner/runner/Cargo.toml --workspace --all-targets --
-D warnings -A clippy::manual_is_multiple_of -A
clippy::filter_map_bool_then`
- `pnpm -r typecheck`
- `pnpm build`
- The PR changes 4 files relative to `runner-rust-semantic-tool-bridge`.
## Risks
Low activation risk. The existing `CodexProvider::start` path still
supplies an empty tool set. The durable backend treats a tool event as
an error until a later PR attaches the durable authorization bridge. The
new transport rejects unknown tools and invalid provider bindings.

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner/runner` semantic tool authorization and
correlation.
**Problem or motivation**
The Rust runner needs a durable representation of the run-scoped tools
that the control plane authorizes. It must reject unknown operations,
catalog drift, invalid values, and conflicting duplicate calls or
results before a provider integration can use those tools.
**Proposed solution**
Add a serialized provider tool bridge. Validate the authorized catalog
and its JSON Schemas. Validate each call and result. Keep pending and
completed identities so retries are idempotent and conflicts fail
closed.
**Alternatives considered**
Trusting provider arguments would bypass the run-scoped catalog.
Validating only in TypeScript would leave the Rust process without a
recovery-safe authorization boundary. Adding provider behavior in this
pull request would make the review unit too broad.
**Roadmap alignment**
This adds a package-local safety boundary for the Codex-first runner
path. It does not enable a new adapter or change an existing direct
adapter path.
## What Changed
- Added the versioned authorized-tool, pending-call, and result
contracts.
- Added canonical SHA-256 catalog binding and drift rejection.
- Added JSON Schema compilation and input and response validation.
- Added duplicate-call and duplicate-result idempotency with conflict
rejection.
- Added bounds for catalogs, schemas, values, and retained call
identities.
- Added the Rust `jsonschema` dependency and its Cargo lock entries.
- Added focused tests for authorization, recovery, envelopes, bounds,
and conflicts.
## Verification
- `cargo fmt --manifest-path packages/paperclip-runner/runner/Cargo.toml
--all -- --check`
- `cargo test --manifest-path
packages/paperclip-runner/runner/Cargo.toml -p paperclip-runner-core`
(64 tests)
- `cargo clippy --manifest-path
packages/paperclip-runner/runner/Cargo.toml -p paperclip-runner-core
--all-targets -- -D warnings -A clippy::manual_is_multiple_of -A
clippy::filter_map_bool_then`
- `pnpm -r typecheck`
- `pnpm build`
- The repository test runner also reached unrelated server worktree
suites. Those suites fail on the current macOS worktree with database
deadlocks and filesystem fixture assumptions. This pull request does not
change those files. The applicable GitHub checks remain the handoff
authority.
## Risks
The main risks are accepting a tool that the run did not authorize and
replaying a conflicting provider result. The bridge validates the
catalog, operation identity, JSON Schema, call identity, and result
identity before it changes durable state. The new Cargo dependency is
package-local. This pull request changes no GitHub workflow and no pnpm
lockfile.

can start safely

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex runtime context materialization.
**Problem or motivation**
The runner needs a private Codex home for each native session. It must
stage only assigned skills, copy local Codex authentication safely, and
validate native MCP bindings before it exposes them to the child
process.
**Proposed solution**
Create an isolated runtime directory. Validate the skill tree before and
after copying it. Make staged skill files read-only. Read authentication
through a no-follow file descriptor with a size bound. Accept only HTTPS
or loopback MCP endpoints and bounded tokens.
**Alternatives considered**
Using the operator Codex home directly would expose unrelated state and
skills. Following symlinks while copying skills or authentication could
escape the assigned source. Accepting arbitrary MCP URLs could send a
bearer token to an untrusted endpoint.
**Roadmap alignment**
This adds a package-local safety boundary for the reviewed Codex runner
path. It does not enable a new adapter or change an existing direct
adapter path.
## What Changed
- Added the native MCP binding contract and strict validation.
- Added isolated Codex home materialization with shell snapshots
disabled.
- Added assigned-skill staging with lexical containment and two-pass
symlink checks.
- Added read-only permissions for staged skill trees.
- Added owner-only authentication staging with no-follow reads and a
size bound.
- Added cleanup for complete and partially materialized runtime
directories.
## Verification
- The focused runtime context suite has 7 passing cases.
- `pnpm --filter @paperclipai/paperclip-runner test:typescript` (36
files, 351 tests)
- `pnpm -r typecheck`
- `pnpm build`
## Risks
The main risks are filesystem escape, secret exposure, and token
delivery to an unsafe endpoint. The materializer rejects symlinks before
and after skill copying, resolves existing source paths, reads
authentication with `O_NOFOLLOW`, applies private permissions, and
restricts MCP URLs to HTTPS or loopback hosts. Existing direct adapters
do not use this package-local runtime context.

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` native backend construction.
**Problem or motivation**
The runner needs one normalized backend seam that constructs the
reviewed Codex driver. The seam must not route OpenCode, ACPX, Claude
Managed, or AWS AgentCore through an incomplete fallback.
**Proposed solution**
Add a Codex backend constructor and a Codex-first factory. Reject every
deferred provider at the factory and provider-specific constructor
boundaries.
**Alternatives considered**
Routing all provider contracts through the Codex protocol facade would
give deferred providers runtime behavior before their implementations
are reviewed. Including all provider backends would also broaden this
pull request beyond the Codex-first series.
**Roadmap alignment**
This connects reviewed runner package layers. It does not enable a new
adapter or change an existing direct adapter path.
## What Changed
- Added the Codex native backend constructor.
- Added the Codex-first native backend factory.
- Preserved the execution contract, runtime instructions, plan
constraints, dynamic tools, transport injection, and durable identity
requirements.
- Rejected every deferred provider with an explicit error.
- Added tests for lazy transport construction and both fail-closed
boundaries.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript` (35
files, 340 tests)
- `pnpm -r typecheck`
- `pnpm build`
- The focused native backend factory suite has 3 passing cases.
## Risks
The main risk is starting the wrong provider or starting a provider
before its runtime is ready. The factory and Codex constructor both
reject non-Codex inputs. Existing direct adapters do not call this
package-local factory.
## Model Used
OpenAI Codex with GPT-5 and repository tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The package now has bounded Codex transport, security, question,
diff, value, and thread helpers
> - Those isolated boundaries can now be composed into one provider
session lifecycle
> - The driver must preserve controller-owned identity, results,
terminals, and recovery invariants
> - Unsupported or mismatched provider traffic must fail closed without
weakening legacy adapters
> - This pull request adds only the Codex app-server driver and its
package-local tests
> - It does not expose or enable the Paperclip Runner adapter
## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex app-server session driver.
**Problem or motivation**
The runner needs a production-shaped Codex session implementation that
turns provider facts into canonical PRP events while keeping task
identity, semantic completion, runtime input, and recovery under
controller authority.
**Proposed solution**
Compose the previously reviewed transport and normalization boundaries
into a Codex-only harness driver with session open/resume, turns,
streaming events, semantic tools, structured questions, goals, lineage,
usage, cancellation, reconciliation, and deterministic persisted
snapshots.
**Alternatives considered**
Keeping the full implementation in one initial transport pull request
would obscure the trust boundaries. Adding the deferred ACPX or OpenCode
paths here would also broaden the provider scope beyond the Codex-first
series.
**Roadmap alignment**
This implements the Codex provider slice inside the package. It does not
enable the runner adapter or change any existing direct adapter path.
## What Changed
- Added the Codex app-server harness driver and session lifecycle.
- Added controller-bound semantic completion and terminal handling.
- Added runtime requests, structured questions, goals, lineage, usage,
steering, interruption, and recovery.
- Added workspace diff and file-reference projection.
- Connected bounded/redacted provider data and notification identity
checks.
- Kept deferred provider identities and replacement behavior out of the
Codex-only driver.
- Added 62 focused driver cases covering lifecycle, security, recovery,
and protocol failures.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript` (34
files, 337 tests)
- `pnpm -r typecheck`
- `pnpm build`
- The focused Codex driver suite has 62 passing cases.
## Risks
The main risks are accepting provider events from the wrong session,
duplicating terminal facts, retaining unsafe provider data, or resuming
a different session. Tests cover pre-turn, cross-thread, stale-turn,
post-terminal, duplicate-result, cancellation, transport loss, provider
identity, workspace, redaction, structured input, and recovery cases.
## Model Used
OpenAI Codex with GPT-5.6 and repository tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Codex driver needs a controller-owned oracle for semantic
completion and replay
> - Provider proposals are advisory and must satisfy the exact task
envelope
> - Persisted events must be bounded and validated before deterministic
replay
> - Live provider behaviors also need one checked-in, schema-validated
fixture
> - This pull request adds that test and conformance layer before the
full driver
> - The runner adapter remains disabled and no production execution path
changes
## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex trace, result-validation, and replay
conformance.
**Problem or motivation**
A provider-completed turn is not sufficient authority to finalize a
Paperclip run. Results must match the controller-owned completion
contract, and persisted provider events must be validated before they
can rebuild controller state.
**Proposed solution**
Add a bounded Codex trace harness that validates result proposals, emits
controller decisions and terminals, verifies live/replay parity, and
rejects malformed persisted streams. Add a validated fixture for runtime
requests, goals, lineage, controls, reconnect identity, and redaction
cases.
**Alternatives considered**
Embedding these assertions only in the production driver would mix
controller authority with provider transport behavior and make
deterministic replay harder to review.
**Roadmap alignment**
This supports the Codex-first experimental runner. It does not enable
the runner adapter or add another provider.
## What Changed
- Added exact task-envelope result validation.
- Added bounded persisted-event validation and deterministic replay.
- Added a controller-owned Codex trace harness and parity assertions.
- Added and validated the checked-in Live console conformance fixture.
- Updated the generated protocol manifest with the fixture source.
- Added focused result and fixture tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused trace-conformance test has 2 passing cases.
## Risks
The main risks are accepting a mismatched semantic result or replaying
corrupted provider history. Validation covers schema, contract revision,
criteria identity, disposition invariants, event identity, uniqueness,
ordering, terminal count, and byte limits.
## Model Used
OpenAI Codex with GPT-5.6 and repository tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Runner replies can refer to files produced inside an assigned
workspace
> - The task page needs stable file metadata without trusting arbitrary
Markdown paths

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` workspace file-reference discovery.
**Problem or motivation**
Assistant-authored Markdown can contain external, absolute, escaping, or
symlinked paths. Reading those paths directly could disclose files
outside the assigned workspace or retain unbounded content.
**Proposed solution**
Parse a bounded set of local Markdown references, normalize them
relative to the workspace, verify canonical paths before reading, reject
symlink escapes, and retain bounded previews plus content digests.
**Alternatives considered**
Leaving path handling inside a provider driver would duplicate a
security-sensitive boundary and make it harder to test independently.
**Roadmap alignment**
This supports the Codex-first experimental runner and future
provider-neutral task projection. It does not enable the runner adapter.
## What Changed
- Added stable workspace file-reference records.
- Added local Markdown link extraction and path normalization.
- Added canonical-path and symlink-escape checks.
- Added bounded file reads, previews, and SHA-256 digests.
- Added focused path, preview, and symlink tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused workspace-reference test has 3 passing cases.
## Risks
The main risk is reading outside the assigned workspace or retaining
excessive data. Tests cover absolute and external paths, symlink
escapes, preview bounds, and deterministic metadata.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Codex thread state arrives as provider-specific goals, lineage,
notifications, and workspace paths

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex thread-state normalization.
**Problem or motivation**
Provider thread data can contain unsupported goal shapes, unrelated
notifications, unsafe workspace paths, or unbounded response values.
Passing it through directly would weaken run isolation and durable-data
bounds.
**Proposed solution**
Normalize goals and lineage into stable runner shapes, accept
notifications only when their run and thread identities match, constrain
workspace references to the assigned root, and retain only bounded safe
provider responses.
**Alternatives considered**
Keeping these rules embedded in the full driver would make the trust
boundary harder to review and test independently.
**Roadmap alignment**
This supports the Codex-first experimental runner. It does not enable
the runner adapter.
## What Changed
- Added normalized Codex thread goals and lineage.
- Added run- and thread-bound notification filtering.
- Added safe workspace-relative path and stat projection.
- Added bounded provider-response retention.
- Added focused normalization and isolation tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused thread-normalization test has 3 passing cases.
## Risks
The main risk is retaining data from the wrong provider thread or
accepting an unsafe workspace reference. Tests cover identity binding,
path normalization, response bounds, goal parsing, and lineage
projection.

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex value and workspace boundaries.
**Problem or motivation**
Raw provider payloads can exceed durable limits or contain credentials.
An invalid working directory can expose host state or escape the
assigned workspace.
**Proposed solution**
Validate the workspace against host and assignment roots. Bound retained
values by depth, count, string length, and byte size. Redact protected
keys and diagnostic credentials.
**Alternatives considered**
Keeping these checks inside the driver would make them harder to review
and reuse at every provider-data boundary.
**Roadmap alignment**
This supports the Codex-first experimental runner. It does not enable
the runner adapter.
## What Changed
- Added assigned-workspace validation.
- Added host home and Codex home overlap checks.
- Added retained payload bounds.
- Added recursive protected-value redaction.
- Added semantic completion tool disposition checks.
- Added focused security and bounds tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused boundary test has 3 passing cases.
## Risks
The main risk is accepting an unsafe workspace or retaining sensitive
provider data. Tests cover root escape, host overlap, size limits,
credential redaction, and completion-tool separation.
## Model Used
OpenAI Codex with GPT-5.6 and repository tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work

> - The benefit is a small compatibility boundary that preserves legacy
question behavior
## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex structured input handling.
**Problem or motivation**
Codex user-input and MCP elicitation requests use different shapes. The
runner needs one canonical question set and must map validated answers
back to the correct provider response.
**Proposed solution**
Normalize native forms into `paperclip.question_set.v1`. Preserve
optional answers, select modes, validation bounds, and stable IDs. Map
canonical responses back only after validation.
**Alternatives considered**
Passing provider-native forms through PRP would couple the app to Codex
and would not preserve the existing provider-neutral question boundary.
**Roadmap alignment**
This supports the Codex-first experimental runner and existing
structured-question compatibility. It does not enable the runner
adapter.
## What Changed
- Added request-kind detection for approval, input, and elicitation
requests.
- Added requestUserInput normalization.
- Added JSON Schema elicitation normalization.
- Added canonical runtime request payloads.
- Added response mapping for Codex answers and MCP elicitation content.
- Added malformed-form and multi-question tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused question adapter test has 3 passing cases.
## Risks
The main risk is changing question semantics. Tests verify optional
answers, single and multi select modes, text validation, duplicate IDs,
numeric elicitation, and canonical response mapping.

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex launch security.
**Problem or motivation**
A provider process can inherit host paths, environment secrets, network
access, or write permissions unless the runner constructs a closed
configuration.
**Proposed solution**
Build explicit app-server arguments and thread parameters. Deny host
roots and network access, allow only a small environment list, and use a
read-only profile for plan mode.
**Alternatives considered**
Relying on ambient Codex defaults would make runner safety depend on
each host installation.
**Roadmap alignment**
This supports the Codex-first experimental runner. It does not enable
the runner adapter.
## What Changed
- Added deny-by-default filesystem rules.
- Added separate execution and planning permission profiles.
- Added network denial.
- Added an explicit environment allowlist.
- Disabled host apps, plugins, memories, multi-agent behavior, and image
generation.
- Added security configuration tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused security configuration test has 3 passing cases.
## Risks
The risk is an overly broad provider launch. Tests verify denied host
roots, read-only context roots, workspace permissions, network denial,
and secret exclusion.

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex event normalization.
**Problem or motivation**
Codex turn diffs need stable file operations and statistics. Raw diff
input must not escape the workspace or grow without bounds.
**Proposed solution**
Parse complete unified diff snapshots into normalized file records.
Bound file count and retained text, reject unsafe paths, and represent
binary changes without text.
**Alternatives considered**
Parsing diffs inside the main driver would make provider lifecycle
review larger and harder to test in isolation.
**Roadmap alignment**
This supports the Codex-first experimental runner. It does not enable an
adapter.
## What Changed
- Added create, modify, delete, rename, mode-change, and binary parsing.
- Added workspace-relative path validation.
- Added file-count and per-file text bounds.
- Added focused rename, binary, hostile path, and size tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused parser test has 2 passing cases.
## Risks
Low risk. This is a pure parser with no file-system access and no
production caller yet.

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex transport.
**Problem or motivation**
The runner needs a safe way to start and communicate with Codex
app-server. Unbounded lines, queued notifications, pending requests, and
inherited credentials would make that boundary unsafe.
**Proposed solution**
Add a JSON-RPC process transport with explicit byte and count limits,
sanitized environment construction, process-group metadata,
server-request handling, redacted diagnostics, and deterministic
closure.
**Alternatives considered**
Adding transport and the full Codex driver in one change would create a
much larger review surface. This pull request isolates the child-process
boundary.
**Roadmap alignment**
This supports the Codex-first experimental runner. It does not enable
the runner adapter.
## What Changed
- Added bounded JSON-RPC request and notification queues.
- Added malformed-message and oversized-line fail-closed behavior.
- Added sanitized Codex environment construction.
- Added process-group tracking and deterministic shutdown.
- Added redacted diagnostics and server-request replies.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused transport test has 6 passing cases.
## Risks
The main risk is child-process cleanup. Tests cover closure, pending
request rejection, queue bounds, process metadata, and malformed input.
## Model Used
OpenAI Codex with GPT-5.6 and repository tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The runner action catalog defines what scenario tools can exist
> - A catalog entry must not grant authority by itself
> - Scenario runs need run-scoped discovery and invocation checks
> - Observable results must not expose protected values
> - This pull request adds an authorized package-local scenario tool
runtime
> - The benefit is deterministic tool testing without production service
authority
## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` scenario tool runtime.
**Problem or motivation**
Scenario tests need to expose only authorized actions. They also need
stable denial records, redaction, and idempotent command handling.
**Proposed solution**
Project the canonical scenario contracts into a visible catalog. Recheck
policy at invocation. Dispatch allowed operations through the mock
control-plane port and return redacted receipts.
**Alternatives considered**
Direct production bindings are outside this pull request. The runtime
uses only the package-local mock port.
**Roadmap alignment**
This supports runner conformance and scenario testing. It does not
enable an adapter or production service call.
## What Changed
- Added run-scoped scenario tool discovery.
- Added claim, role, task-mode, and policy authorization.
- Added input validation, redaction, and authorization records.
- Added fake-agent and Codex definition projections.
- Added deterministic mock dispatch and idempotency coverage.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused semantic runtime test has 10 passing cases.
## Risks
Low risk. The runtime is package-local and uses the mock control-plane
port. It creates no production binding.
## Model Used
OpenAI Codex with GPT-5.6 and repository tool use.

work
> - The Paperclip Runner needs a stable list of semantic actions

groups

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` protocol contracts.
**Problem or motivation**
The runner does not yet have a complete canonical inventory for domain
and administration actions. Later authorization code cannot project a
stable operation catalog without this inventory.
**Proposed solution**
Add the remaining action contracts and aggregate all 41 actions.
Validate every declared live and scenario projection with its own
schema.
**Alternatives considered**
Binding these actions directly to production services would combine data
contracts with authority. This pull request keeps every production
service binding unbound.
**Roadmap alignment**
This change supports the experimental Paperclip Runner. It does not
enable the runner or change an existing adapter.
## What Changed
- Added 14 domain and administration action contracts.
- Added the complete immutable 41-action catalog.
- Added validation for live inputs and outputs.
- Added validation for scenario inputs and capability-result envelopes.
- Kept every production service binding unbound.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The focused catalog test validates 41 actions.
## Risks
Low risk. This pull request adds package-local contract data and tests.
It does not authorize an action or change an adapter.
## Model Used
OpenAI Codex with GPT-5.6 and repository tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents collaborate through discovery, delegation, dependencies, and
governed approvals
> - These optional operations need stable contracts before any run may
discover them
> - The core action contracts are already isolated in the lower stack

definitions
> - It does not grant claims or bind production services
> - The benefit is a reviewable contract layer for later run-scoped
authorization
## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner protocol action contracts
**Problem or motivation**
Optional collaboration operations need one provider-neutral definition
for policy metadata, documentation, live and scenario schemas, and
canonical examples.
**Proposed solution**
Add one immutable module for each discovery, delegation, dependency, and
governance action. Add a collaboration aggregate and validate all
examples with JSON Schema.
**Alternatives considered**
These contracts could land with executable authorization. That would
make contract review depend on runtime policy and server service
bindings.
**Roadmap alignment**
This supports the existing experimental Paperclip Runner rollout. It
does not make any optional operation discoverable or invocable.
## What Changed
- Add 13 collaboration and governance action definitions.
- Add immutable policy, schema, documentation, and example data.
- Add a collaboration-only aggregate.
- Validate every action example against its declared schema.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The branch changes 15 files relative to its declared base.
## Risks
Low production risk. The declarations do not grant claims or contain
executable service bindings. Tests require optional placement, immutable
metadata, stable identities, and schema-valid examples.

## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner protocol action contracts
**Problem or motivation**
The runner has an older compact catalog, but it does not single-source
the full policy metadata, documentation, live shape, scenario shape, and
examples for each core action.
**Proposed solution**
Add one immutable definition module per core action. Add an internal
core aggregate and validate every input and output example against its
declared JSON Schema. Keep all production authorization and execution
unavailable.
**Alternatives considered**
All 41 action definitions could land in one pull request. That would
create more than 7,000 changed lines and reduce useful review depth.
**Roadmap alignment**
This supports the existing experimental Paperclip Runner rollout. It
does not enable the adapter or expose any new production tool.
## What Changed
- Add 14 core protocol action definitions.
- Add immutable policy, schema, documentation, and example data for each
action.
- Add a deep-freeze helper and a core-only aggregate.
- Validate all core examples with JSON Schema.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The branch changes 17 files relative to its declared base.
## Risks
Low production risk. These declarations do not contain executable
authorization or service bindings. The main risk is schema drift. Tests
validate operation identity, placement, immutability, and canonical
examples.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work

state changes
> - Conformance tests need this authority without a live server or
database
> - The existing in-memory port covers transport facts but not

## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner testing and semantic capability contracts
**Problem or motivation**
Later semantic action slices need deterministic company, actor, task,
governance, workspace, secret, budget, routine, and audit state. A live
Paperclip server would make those tests slow and environment-dependent.
**Proposed solution**
Add serializable capability fixture types and an in-memory control-plane
adapter. Enforce company scope, claims, roles, idempotency, redaction,
faults, and audit records. Export the adapter only from the testing
entry point.
**Alternatives considered**
The tests could mock each action separately. That would duplicate
authorization rules and would not verify state transitions across
multiple actions.
**Roadmap alignment**
This supports the existing experimental Paperclip Runner rollout. It
does not enable production semantic operations or change app execution.
## What Changed
- Add deterministic capability fixture types and seed state.
- Add an in-memory capability control-plane adapter.
- Enforce run, company, actor, claim, role, and idempotency boundaries.
- Model governed task, document, interaction, workspace, secret,
routine, and audit changes.
- Add deterministic tests and testing-entry-point exports.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The branch changes 5 files relative to its declared base.
## Risks
The main risk is a permissive mock that hides a production authorization
error. The adapter fails closed for missing claims, wrong roles,
cross-company access, duplicate mutations, invalid state, and restricted
secret access. Tests cover each fixture domain and serialized restore
behavior.

changes
## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner testing and conformance support
**Problem or motivation**
The public runner contracts have unit tests, but later provider and
server slices need a deterministic way to exercise session, event,
replay, checkpoint, and result behavior together.
**Proposed solution**
Add in-memory implementations of the harness-driver and control-plane
ports. Add a canonical conformance fixture and runner. Export these
utilities only from `@paperclipai/paperclip-runner/testing`.
**Alternatives considered**
The tests could start a real provider or server. That would make the
conformance gate slower, less portable, and dependent on credentials or
network state.
**Roadmap alignment**
This supports the existing experimental Paperclip Runner rollout. It
does not enable a production adapter or change current app execution.
## What Changed
- Add a deterministic harness-driver implementation.
- Add an in-memory control-plane adapter with replay and checkpoint
support.
- Add a canonical provider-neutral conformance fixture.
- Add a reusable conformance runner and contract tests.
- Export the helpers from the package testing entry point only.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The branch changes 10 files relative to its declared base.
## Risks
Low risk. This pull request adds test-only adapters and conformance
helpers. It does not select a runtime or change production behavior.
Contract tests verify event identity, replay, checkpoints, and
deterministic results.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Semantic tools cross a trust boundary between a provider and the
control plane

receipt pairs

fixtures
> - It keeps newer sequence and gap safety limits from the current stack
> - The benefit is auditable semantic activity before more providers use
it
## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner
**Problem or motivation**
Semantic tool calls have basic authorization records, but durable replay
does not yet cover reconciled calls, denial redaction, duplicate
receipts, governance targets, or artifact references.
**Proposed solution**
Add bounded semantic receipt builders, a reconciled phase, strict pair
binding, fail-closed version checks, and generated replay oracles for
the important lifecycle cases.
**Alternatives considered**
The runner could store provider-native tool payloads. That would weaken
protocol portability and make redaction and retry behavior
provider-specific.
**Roadmap alignment**
This supports the existing experimental Paperclip Runner rollout. It
does not enable a production adapter.
## What Changed
- Add semantic input and result receipt builders.
- Add optional reconciliation receipts for pending calls.
- Reject unsupported semantic receipt versions.
- Validate receipt correlation, operation, idempotency, and digest
bindings.
- Add deterministic replay fixtures and generated golden outputs.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- Replay golden and protocol manifest checks pass.
- The branch changes 27 files relative to its declared base.
## Risks
The main risk is accepting a receipt that belongs to another call or
replaying a duplicate as a new mutation. Binding checks compare
correlation, operation, idempotency, and content digest fields. Fixtures
cover denials, duplicates, governance chains, optional fields,
artifacts, and unsupported versions.

## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner
**Problem or motivation**
The runner contracts do not yet have a shared session loop. Each backend
would otherwise duplicate event handoff, terminal handling, recovery
cursors, timeouts, and checkpoint behavior.
**Proposed solution**
Add the native session runtime, backend interfaces, control-plane port,
harness driver contract, deterministic conformance helpers, and bounded
tests.
**Alternatives considered**
The server could own this loop. That would mix provider process behavior
with server persistence and authority logic.
**Roadmap alignment**
This is part of the existing experimental Paperclip Runner rollout. It
does not enable a production adapter.
## What Changed
- Add a provider-neutral native session execution loop.
- Add recovery cursor reconciliation and checkpoint hooks.
- Add bounded timeout and governed-wait behavior.
- Add harness driver and control-plane conformance helpers.
- Add deterministic backend and session runtime tests.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- Protocol generation and manifest checks pass.
- The branch changes 14 files relative to its declared base.
## Risks
The main risk is a session that hangs, duplicates an event, or restores
the wrong cursor after reconnect. Tests cover terminal events, timeouts,
durable handoff, duplicate receipts, recovery, continuity breaks, and
checkpoint updates. The change remains package-local.

## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner
**Problem or motivation**
The runner has protocol transport and Codex support, but later backends
do not have one public contract for execution input, runtime context,
completion output, and recovery state.
**Proposed solution**
Add versioned native execution input parsers, model envelopes,
completion result helpers, runtime context contracts, and durable
recovery types. Keep these changes package-local. Do not change server
runtime selection.
**Alternatives considered**
Each provider could define its own server-facing input. That would
couple server orchestration to provider details and make compatibility
harder to verify.
**Roadmap alignment**
This is part of the existing experimental Paperclip Runner rollout. It
does not enable a new production adapter.
## What Changed
- Add versioned native execution input contracts and strict parsers.
- Add provider-neutral runtime context and completion contracts.
- Add durable recovery and local runner types.
- Add structured question compatibility and parser tests.
- Export only the contracts that exist in this stack layer.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- Protocol generation and manifest checks pass.
- The branch changes 12 files relative to its declared base.
## Risks
The main risk is accepting malformed or future input as a supported
contract. The parsers reject unknown required versions and unknown
fields. The change is package-local and does not select or start the
experimental runner.

## Thinking Path
> - The runner already persists PRP events, but provider-native activity
needs one bounded, provider-neutral vocabulary before additional
providers can be added safely.
> - The protocol catalog must describe capabilities without enabling or
authorizing a provider.
> - Provider normalization must not require an ACPX runtime dependency
merely to compile the shared event layer.
> - This pull request adds the event contract and pure normalizers only;
provider transports and production selection remain unchanged.
## Linked Issues or Issue Description
This is the first follow-up stacked on #12321. Codex, OpenCode, and ACP
runtimes expose different activity shapes. Without canonical
normalization, downstream task threads and traces would need
provider-specific branching and could retain unbounded or unsafe
payloads.
## What Changed
- Expand the PRP provider descriptor and canonical activity event
families.
- Add bounded Codex, OpenCode, and ACP event normalizers for plans,
tools, research, delegation, artifacts, review, safety, waits, and
notices.
- Preserve strict schema validation and regenerate the checked-in schema
bundle and manifest.
- Use a structural ACP event input so the provider-neutral layer does
not introduce or authorize an ACPX runtime dependency.
- Export the provider-event contract from the existing package root.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm --filter @paperclipai/paperclip-runner test:typescript` — 11
files and 88 tests passed.
- `pnpm -r typecheck`
- `pnpm build`
- `git diff --check`
- The local full repository runner reached unrelated macOS
workspace-path fixture failures; the affected runner suites pass and the
repository CI shards are the handoff authority.
- Diff against the declared base: 8 files.
## Compatibility Boundary
- No provider transport, adapter, server route, feature flag, or runtime
selection changes.
- Catalog presence does not authorize discovery or execution.
- Existing Codex execution continues through its current path.
- No dependency, migration, workflow, or lockfile change.
## Risks
The main risk is accepting malformed or unbounded provider payloads.
Schema validation remains fail-closed, text/output fields are bounded
and redacted, unsafe paths and URLs are discarded, and representative
variants for every declared event family are covered by tests.
## Model Used
OpenAI Codex, GPT-5 family. The client does not expose the exact
deployment ID or context window. Agentic reasoning, tool use, and code
execution were enabled.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The experimental Paperclip Runner can execute a guarded Codex run
and persist provider-neutral events.
> - The task page still reads direct-adapter transcripts and cannot
present those native events.
> - Structured runner questions must also use the existing task
interaction experience.
> - Runtime selection must use the persisted run mode, not an adapter
name or a current feature flag.
> - This pull request projects native events and questions into the
existing task thread.
> - Direct adapters keep their existing transcript, composer,
interaction, and finalization paths.
> - The benefit is a complete native Codex task thread without a
behavior change for existing adapters.
## Linked Issues or Issue Description
Refs #12202. This pull request replaces that stale implementation on
current `master`.
**What happened?**
The server persists native runner events and structured input requests.
The task page only consumes direct-adapter transcripts. A native run
therefore cannot present a complete transcript, usage, or question flow
through the normal task experience.
**Expected behavior**
Native runs project persisted provider-neutral events into the existing
task thread. Native structured questions use the existing interaction
card. Direct adapters retain their current behavior.
**Steps to reproduce**
1. Enable the experimental runner.
2. Start a native Codex run that emits progress, usage, a structured
question, and a final reply.
3. Open the task page.
4. Observe that the direct-adapter transcript path cannot project the
native event records.
**Paperclip version or commit**
`master` at `67f9867bc`.
## What Changed
- Add the canonical structured-question validator and shared contract
exports.
- Materialize native input requests as existing task interactions.
- Validate native answers and deliver them through the durable
question-response receipt.
- Resume the original PRP request with an idempotent `request.resolve`
command.
- Project native messages, tool activity, cumulative usage, and final
replies into the existing transcript model.
- Propagate persisted `runtimeMode` to the task page and select native
handling only for `runtimeMode: "native"`.
- Expire pending interactions through the shared issue service on every
terminal transition, including decisions, stalled reviews, tree control,
and pipeline retry cleanup.
- Queue native run cancellation while a transaction is open and execute
it only after the owning transaction commits.
- Keep nonterminal and non-runner issue paths on their existing service
call shapes and behavior.
## Verification
- `pnpm --filter @paperclipai/server typecheck` — passed, including the
Rust runner release build and protocol/catalog drift gates.
- Focused native-thread and lifecycle suites — 18 files and 481 tests
passed during review.
- `issue-execution-policy-routes.test.ts` — 19/19 passed after the final
transactional-queue expectation update.
- `issue-agent-mutation-ownership-routes.test.ts` — 87/87 passed in the
final isolated compatibility rerun.
- GitHub Actions — policy, build, canary, typecheck/release registry, 5
serialized server shards, 8 general-test shards, 3 browser shards, and
both aggregate gates passed on `7793f3193`.
- Security — Snyk, Socket Project Report, Socket PR Alerts, and
Superagent passed.
- Greptile — 5/5 on `7793f3193`; all actionable review threads resolved.
- `git diff --check` — passed.
- Diff against `master`: 44 files.
## Compatibility Boundary
- Native transcript polling only runs when the persisted run reports
`runtimeMode: "native"`.
- Missing or legacy runtime modes continue through
`useLiveRunTranscripts`.
- Legacy questions keep the existing optional free-text choice.
- Native closed select sets can suppress that legacy fallback.
- Terminal cleanup uses the same issue service for native and legacy
interactions; only a bound native question schedules a native run
cancellation.
- Native cancellation happens after transaction commit, so failed or
rolled-back writes do not cancel a still-valid run.
- The durable delivery service checks the original native request before
it considers a continuation run.
- This pull request adds no migration, dependency, workflow, manifest,
or lockfile change.
## Risks
The main risk is routing a direct-adapter task through native handling
or changing terminal issue behavior. The implementation selects the
native path only from persisted runtime facts, retains the existing
nonterminal call shape, and schedules native cancellation only for a
validated bound native question after commit. Focused and
repository-wide tests cover both paths. Native requests remain bound to
the company, issue, run, and agent; answers are validated, durable, and
idempotent across reconnects.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Apps give those agents governed access to external tools.
> - Provider catalogs must match each provider's current protocol and
credential contract.
> - Postman method labels and API-key placement were outdated.
> - Shopify now offers a UCP commerce endpoint that needs a managed
agent-profile argument.
> - This pull request updates both providers and documents the complete
connection-authoring workflow.
> - The benefit is accurate setup, safer runtime defaults, and a
repeatable provider review process.
## Linked Issues or Issue Description
Refs #11965
This is stack 10 of 11. It depends on stack 9 and preserves the final
catalog work recovered from #11965.
Related: #5904 covers Shopify skill routing. This pull request covers
the Apps connection contract instead.
## What Changed
- Update Postman hosted MCP methods, capability choices, default
selection, and bearer-token placement.
- Add Shopify UCP commerce and Storefront compatibility methods with
public-store prerequisites.
- Inject the reviewed Shopify UCP agent profile at runtime and remove
that managed field from user input schemas.
- Classify Shopify checkout completion and cancellation as destructive
actions.
- Expand the connection authoring runbook from provider research through
verification and pull request handoff.
- Add focused shared, server, and UI coverage.
- Make the approved-execution waiter phase-aware so slow preparation
cannot consume the provider execution timeout and grace period.
- Settle legacy pre-execute-on-approve requests and invocations as
failed, clear their stale idempotency key, and allow a fresh governed
approval instead of leaving work stuck in `executing`.
## Verification
- `pnpm exec vitest run packages/shared/src/app-definitions.test.ts
server/src/__tests__/tool-access-service.test.ts
ui/src/pages/apps/AppsConnect.test.tsx -t
"Postman|Shopify|normalizeConnectionMethodConfig|classifyRisk"` (16

- `pnpm exec vitest run server/src/__tests__/tool-gateway.test.ts -t
"enforces policy, approvals, retries, rate limits, and company
boundaries for connected remote MCP calls"` (1 passed)
- `pnpm exec vitest run
server/src/__tests__/tool-gateway-service.test.ts` (21 passed; includes
legacy approval settlement and fresh-approval recovery)
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm check:token-gates`
- `pnpm -r typecheck`
- `pnpm build`
## Risks
- Shopify UCP calls now include a Paperclip-managed agent profile that
overrides caller input at the same path.
- Postman EU credentials now use the hosted MCP server's bearer-token
contract instead of the general REST API header.
- The catalog generator and checked-in definitions change together to
prevent regeneration drift.
- Approved execution preparation has an explicit two-minute bound;
provider execution retains its own 65-second timeout and persistence
grace starting from durable provider start.
- Legacy approvals created before execute-on-approve are intentionally
terminalized and must be requested again under the current signed
contract.
> I checked `ROADMAP.md`. This provider update does not duplicate
planned core work. The related open Shopify PR addresses skill routing,
not Apps connections.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Connection intents need secure provider implementations to complete
setup.
> - Some providers use managed OAuth or external credential brokers.
> - Those tokens must stay out of durable Paperclip state and fail
closed when refresh fails.
> - This pull request adds managed connector backends and the required
storage contract.
> - The benefit is safer provider setup with governed credential
lifecycles.
## Linked Issues or Issue Description
Refs #11965
This is stack 8 of 11. It depends on stack 7 and replaces another
reviewable part of #11965.
## What Changed
- Add managed Google Workspace and external connector backends.
- Add Vercel Connect support without storing provider bearer tokens.
- Add replay-safe migration 0232 and its generated snapshot.
- Fail closed and clear stale token bindings when organization OAuth
refresh needs reauthorization.
## Verification
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts`
- Result: 194 tests passed.
- `pnpm --filter @paperclipai/db check:migrations`
- `pnpm build`
- `pnpm exec vitest run --project @paperclipai/server
server/src/services/remote-url-credentials.test.ts` (5 passed, including
URL userinfo vault extraction)
## Risks
- Broker metadata errors can block provider setup.
- OAuth refresh failure disables the shared organization connection
until reauthorization.
- Migration 0232 is generated, ordered after 0231, and safe to replay.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents need a governed way to request app connections during issue
work.
> - The catalog now describes the available providers and setup methods.
> - A request must become a durable, company-scoped intent before an
operator acts on it.

setup.
## Linked Issues or Issue Description
Refs #11965
This is stack 7 of 11. It depends on stack 6 and replaces another
reviewable part of #11965.
## What Changed
- Add connection intent types, validation, service logic, and routes.
- Add agent runtime tools and CLI support for connection requests.
- Add issue-thread interaction support for connection intents.
- Add runtime, route, adapter, and contract tests.
- Hold the final resolved-continuation row lock through asynchronous
adapter preparation until an actual process spawn, so parking or
reassignment cannot cross that boundary.
- Report Hermes Gateway's first remote run request through the shared
dispatch hook so the resolved-intent lock is released at the true
dispatch boundary.
- Revalidate the addressed user's live non-viewer membership and
connection-management authority for every intent mutation, including
OAuth completion.
## Verification
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts`
- Result: 176 tests passed.
- `pnpm build`

"addressed-user mutation"` (1 passed)
- `pnpm exec vitest run --project @paperclipai/server
server/src/__tests__/tool-access-service.test.ts -t "binds OAuth
callback completion to the initiating board session"` (1 passed)
- `pnpm --filter @paperclipai/hermes-paperclip-adapter test --
src/gateway/server/execute.test.ts` (23 passed; includes dispatch-hook
ordering and exactly-once coverage)
- `pnpm --filter @paperclipai/hermes-paperclip-adapter typecheck`
## Risks
- A malformed intent could create an unusable operator request.
- Validators and company checks reject invalid or cross-company
requests.
- The final continuation gate holds the issue row lock through adapter
preparation until process or remote dispatch; later operator changes use
the normal active-run interruption path.
- The change does not add a database migration.

## What Changed
- Add company and user connection grants.
- Add delegated identity and membership rules.
- Synchronize database, shared, server, and UI contracts.
- Register the grant-member replacement route in the OpenAPI surface in

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - App connections must work in both the operator UI and agent tool
gateway.
> - The first stack layer adds secure remote connections.

recover.
## Linked Issues or Issue Description
Refs #11965
This is stack 2 of 11. It depends on stack 1 and replaces another
reviewable part of #11965.
## What Changed
- Improve remote tool gateway connection behavior.
- Add clearer app setup, test, and recovery states.
- Add focused server and UI tests for the new paths.
- Keep the diff isolated from later identity and catalog work.
- Stabilize DNS-pinned remote HTTP protocol fixtures and the
managed-runtime public-origin fixture for this independently tested
layer.
## Verification
- `pnpm -r typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts` (150 passed)
- `pnpm test:run`
- `pnpm check:token-gates`
- `pnpm build`
## Risks
- Gateway errors now surface through new user-facing states.
- A stale connection can require a new setup attempt.
- The change does not add a database migration.
- The injected HTTP transport and public URL are test-only fixtures;
production DNS pinning and runtime behavior are unchanged.

## Linked Issues or Issue Description
Refs #11965
This is stack 1 of 11. It replaces the first reviewable part of #11965.
## What Changed
- Add guarded remote MCP setup and credential handling.
- Add PostHog OAuth and API key connection methods.
- Add focused server, shared contract, and UI coverage.
- Keep the migration replay-safe and idempotent.
- Give the late-close security regression the same 10-second CI headroom
as the adjacent real-timer handshake test.
- Synchronize fake-timer handshake tests at the exact ensure-session
boundary so real filesystem setup cannot race the fake deadline.
- Drive PTY overflow coverage only after listener registration so
scheduling cannot reorder the test fixture.
## Verification
- pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts
server/src/__tests__/plugin-worker-manager.test.ts (220 passed; affected
cases also passed five focused stress repetitions)
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "never leaks a
sandbox-provided value from a late close rejection into logs or the
result"` (1 passed)
- `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "never
promotes a late ensureSession resolution|closes a late-resolving real
handle exactly once"` (2 passed)
- `pnpm -r typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts`
- `pnpm --filter @paperclipai/db check:migrations`
- `pnpm build`
## Risks
- Remote endpoint validation can reject configurations that previously
passed without checks.
- OAuth configuration errors can block setup until the operator corrects
the provider settings.
- The migration uses guarded statements so repeated execution is safe.
- The test-only synchronization changes do not affect runtime behavior;
they remove filesystem/fake-clock and listener-registration races
observed under parallel CI load.

Co-authored-by: Paperclip <noreply@paperclip.ing>
## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The server admits agent work through heartbeat scheduling and
execution paths
> - Operators need to stop new work before maintenance or a graceful
shutdown
> - A process restart alone does not provide a reusable admission
control primitive
> - This pull request adds an instance API that holds new task admission
and reports process quiescence
> - The benefit is a small, auditable control that lets operators wait
for active work without a restart
## Linked Issues or Issue Description
**Problem or motivation**
Operators cannot hold new task admission without restarting the
Paperclip process. A restart can interrupt maintenance flows and does
not provide a status signal for active work.
**Proposed solution**
Add `GET /instance/task-drain`, `POST /instance/task-drain`, and `DELETE
/instance/task-drain`. The server keeps the drain state in process
memory, applies it to every scheduling suppression path, supports an
optional TTL up to 24 hours, and reports active wake and run counts.
**Alternatives considered**
A timer would clear the drain after its TTL, but it could keep the
Node.js event loop open during shutdown. A database row would add
storage and query work for process-local state. The implementation uses
lazy expiry and process memory instead.
**Roadmap alignment**
The change supports the roadmap goal for enforced outcomes and safe
recovery actions. It does not duplicate a listed roadmap item.
**Additional context**
This is a server and shared-package change. It adds no user interface
and no database migration.
## What Changed
- Add process-local task-drain state with lazy TTL expiry.
- Add task-drain admission suppression to the shared heartbeat resolver.
- Add instance routes to read, start, and stop a task drain.
- Add validation for positive TTL values and the shared 24-hour maximum.
- Add activity records for drain mutations and tests for status, access
control, validation, and suppression.
## Verification
- Run `pnpm exec vitest run --project @paperclipai/server
server/src/__tests__/heartbeat-task-drain.test.ts
server/src/__tests__/instance-settings-routes.test.ts
server/src/__tests__/heartbeat-scheduling-suppression.test.ts`.
- Run `pnpm --filter @paperclipai/shared exec tsc --noEmit`.
- Run `pnpm --filter @paperclipai/server exec tsc --noEmit` and compare
its known pre-existing errors with the base commit.
- Confirm that pull request CI reaches a terminal green state.
## Risks
The drain state exists only in process memory, so a restart clears it.
This behavior matches the process-local design. A drain without a TTL
remains active until an operator calls the delete route. The status
route reads in-memory activity sets and does not query stale database
rows.
## Model Used
OpenAI Codex, GPT-5, extended reasoning with tool use and code
execution. The exact runtime context window is not exposed by the
execution environment.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip uses adapters to connect agents and model providers to its
control plane
> - The sandbox login panel supports displayed-code login for selected
adapters
> - Grok users need the same login path and a private credential home
for later runs
> - This pull request adds Grok support to the shared device-login path
and preserves the existing Codex path
> - The benefit is one secure login flow for both adapters with
company-scoped credential storage
## Linked Issues or Issue Description
**Agent or provider**
Grok Local needs displayed-code login support in the sandbox login
panel.
**Why this adapter is useful**
This change lets users sign in to Grok from the sandbox login panel. It
also gives later Grok runs access to the stored credential.
**How the agent is invoked**
The Grok local adapter uses its login command through the shared
displayed-code login flow. Later runs receive the managed home through
`GROK_HOME`.
**Additional context**
The change uses adapter-scoped login lifecycle handling. It stores the
credential in a company-scoped directory with mode `0700`, and it stores
the credential file with mode `0600`.
## What Changed
- Rename the shared device-login modules to adapter-neutral names.
- Scope the shared login lifecycle to a closed adapter set.
- Return the device-login URL that the provider prints.
- Add the Grok prompt parser, login command, capability, and login panel
entry.
- Store the Grok credential in a private, company-scoped home directory.
- Pass `GROK_HOME` to later Grok runs.
- Add tests for the Grok adapter, the Daytona sandbox provider, the
server login path, and the user interface.
## Verification
- Run `pnpm vitest run
packages/adapters/grok-local/src/server/adapter-auth-promotion.test.ts`.
- Run the Grok adapter package suite.
- Run the Daytona sandbox provider suite.
- Run the server device-login suites.
- Run the user interface suite.
- Confirm the full CI suite passes.
## Risks
The change extends shared login lifecycle code to another adapter. A
regression could affect Codex login. The credential path uses explicit
`chmod` calls to keep the directory at mode `0700` and the file at mode
`0600`.
## Model Used
OpenAI Codex, GPT-5. The runtime used tool calls and code review
support. The runtime did not provide a context-window value.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The adapter layer carries sandbox requests to host processes.
> - The HTTP/2 bridge used one process-wide byte ledger for all routes.
> - One busy route could exhaust that shared budget and move another
route to file transport.
> - This pull request gives each host retention site a fixed byte bound
and limits concurrent HTTP/2 streams.
> - The benefit is local protection: one route cannot consume the byte
budget of another route.
## Linked Issues or Issue Description
**What happened?**
The HTTP/2 bridge used one aggregate byte ledger for retained bytes
across all routes. A busy route could exhaust the shared budget and
force an unrelated route to use file transport.
**Expected behavior**
Each route should protect its own retained bytes. A reset on one HTTP/2
stream should cancel only that stream's host forward.
**Steps to reproduce**
1. Start the HTTP/2 bridge with multiple sandbox routes.
2. Send enough retained data through one route to reach the aggregate
byte limit.
3. Send a request through a sibling route.
4. Observe that the sibling route can fall back to file transport
because the first route used the shared ledger.
**Paperclip version or commit**
`47639e227e78e3c5e0dd1a3c0e2d792fe86895a3`
**Deployment mode**
Built from source with the adapter-utils and server test suites.
## What Changed
- Bound each host retention site with a fixed local byte limit.
- Limited concurrent live HTTP/2 streams with one built-in stream limit.
- Bound each host forward and response-body read to its own HTTP/2
stream lifetime.
- Removed the process-wide byte ledger, its environment override, its
metrics, and its file-transport fallbacks.
- Added tests for the stream limit, host body budget, and sibling-stream
cancellation.
## Verification
- Run `pnpm vitest run --project adapter-utils`.
- Confirm that 996 adapter-utils tests pass.
- Confirm that `test_live_forward_work_never_passes_the_stream_limit`
passes.
- Confirm that `test_the_host_body_budget_matches_the_stream_limit`
passes.
- Confirm that the sibling-stream cancellation test passes.
- Run `pnpm tsc --noEmit`.
- Confirm that all pull request checks pass.
## Risks
The bridge no longer uses a process-wide byte ledger. A local bound or
stream limit that is too low can reject or delay valid work. The tests
cover the new limits and stream cancellation behavior.
## Model Used
OpenAI GPT-5 Codex. Runtime model ID: GPT-5. The model used code

window size.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The CLI test suite uses embedded Postgres for worktree checks.
> - Several tests start a cluster and run migrations on each test.
> - Runner contention can make this cost class exceed small hand-written
time budgets.
> - A timed-out test can also leave the cluster alive while cleanup
removes its data directory.
> - This pull request gives the cost class one measured timeout and
registers cleanup for the timeout path.
> - The benefit is stable tests and fewer orphaned embedded Postgres
processes.
## Linked Issues or Issue Description
No public GitHub issue tracks this defect. Related PRs #10987 and #10961
address wider embedded-Postgres test setup issues. This pull request
addresses the CLI timeout and cleanup path described below.
**What happened?**
Five CLI tests used different hand-written time budgets while they
started embedded Postgres and ran migrations. Runner contention made one
test exceed its budget. A timeout also skipped the `finally` cleanup
path and left a Postgres process alive.
**Expected behavior**
Each embedded-Postgres test gets a budget that covers measured runner
contention. Cleanup stops the cluster before the test removes its data
directory, including after a timeout.
**Steps to reproduce**
1. Run `npx vitest run cli/src/__tests__/worktree.test.ts` on a
contended runner.
2. Observe the embedded-Postgres tests take longer than their small
hand-written budgets.
3. Inspect the process list after a timeout and observe an orphaned
Postgres process.
**Paperclip version or commit**
The defect reproduces on `master` before this pull request.
**Deployment mode**
Built from source with Vitest.
**Installation method**
Built from source with pnpm.
## What Changed
- Export `EMBEDDED_POSTGRES_TEST_TIMEOUT_MS` from the embedded-Postgres
test helper.
- Apply the shared timeout to every test defined by
`itEmbeddedPostgres`.
- Replace the five hand-written timeout values in `worktree.test.ts`.
- Register temporary-directory removal and cluster stop with
`onTestFinished` in the correct order.
- Restore the working directory during timeout cleanup.
## Verification
- `npx vitest run cli/src/__tests__/worktree.test.ts` passes 63 tests.
- `npx vitest run cli/src` passes 424 tests across 59 files.
- `tsc --noEmit` in `cli/` adds no new error in the touched files.
- CI must pass on the pull request head.
- Greptile must report 5/5 with no unresolved blocking thread.
## Risks
- Low risk. The change affects test helpers and test cleanup only.
- The shared budget can lengthen a failing test before Vitest reports
the failure.
- The cleanup order depends on Vitest callback order, which the tests
now use explicitly.
## Model Used
OpenAI Codex, GPT-5. The model used tool calls and code review support.
The context window size and internal reasoning mode were not exposed in
this run.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Adapter utilities start and control agent sessions.
> - The ACP startup handshake can stay pending when the sandbox
transport closes.
> - A pending handshake keeps the run active and prevents a clear
operator result.
> - This pull request bounds the handshake and fences its abandoned
promise.
> - The result gives each startup failure a terminal state and a safe
host-authored diagnostic.
## Linked Issues or Issue Description
No matching public issue or pull request appeared in the GitHub search
for this failure. The issue details follow.
**What happened?**
The adapter engine awaited `runtime.ensureSession()` without a startup
bound. A lost sandbox transport could leave the await pending.
**Expected behavior**
The engine must end the run when the startup deadline expires or the
duplex transport closes. A late session result must not reopen the
settled run.
**Steps to reproduce**
1. Start an ACP-backed agent run.
2. Keep the ACP initialization call pending.
3. Let the startup deadline expire or close the duplex transport.
4. Confirm that the run reaches a terminal state and that a late session
result does not reopen it.
**Paperclip version or commit**
`66e1c0df8b23cb8354b36dd446d9548dc4389191` merge base.
**Deployment mode**
Local dev (`pnpm dev`).
**Installation method**
Built from source (`pnpm dev`).
**Agent adapter(s) involved**
Custom / external plugin adapter.
**Database mode**
Not database-related.
**Relevant logs or output**
The new tests use fixed host-authored diagnostics for handshake guard
failures and late close failures.
**Additional context**
The change updates the execution semantics document and adds regression
coverage. The three existing failures in `execute.test.ts` also occur at
the merge base.
## What Changed
- Bound `runtime.ensureSession()` with a startup deadline and a duplex
transport loss check.
- Added terminal error codes for handshake timeout and transport loss.
- Fenced late session resolution and rejection so the settled run has
one owner.
- Suppressed sandbox-controlled diagnostic values on the guard-failure
and late-close paths.
- Added regression tests for timeout, transport loss, late resolution,
and late close rejection.
- Documented the startup live-path contract.
## Verification
- `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit` exits 0.
- The engine test suite runs from the repository root.
- The new regression cases pass.
- The three known failures remain the only failures and also fail at the
merge base. The board approved this pre-existing test exception.
- Cold start and session resume cases pass.
- All required GitHub checks pass.
- Greptile reports 5/5 with no open P2 findings, recommendations, or
follow-ups.
## Risks
The startup guard changes only the ACP startup path. A slow but valid
startup can now end at the configured deadline. The fence closes a late
handle once and records fixed host-authored diagnostics.
## Model Used
OpenAI Codex, GPT-5, current model version, tool use and code execution,
with the full task context.

Co-authored-by: Paperclip <noreply@paperclip.ing>
## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Remote agent adapters use a process-session wrapper inside a
sandbox.
> - Some supported sandbox filesystems do not report inode creation
time.
> - The wrapper rejects a zero creation time before it launches the
agent.
> - This pull request accepts that filesystem shape and keeps the
existing change-time probe.
> - The benefit is that valid sandbox runs can start without a
birth-time field.
## Linked Issues or Issue Description
**What happened?**
The remote process-session wrapper exited before it launched the agent
when the sandbox filesystem reported `birthtimeMs` as zero.
**Expected behavior**
The wrapper must start on a filesystem that does not report inode
creation time.
**Steps to reproduce**
1. Start the remote process-session wrapper.
2. Make `lstat()` report a zero `birthtimeMs` for its session directory.
3. Observe that the pre-fix wrapper terminates before the child process
starts.
**Paperclip version or commit**
Reproduced from `66e1c0df8b23cb8354b36dd446d9548dc4389191`.
**Deployment mode**
Self-hosted server with a remote sandbox runtime.
## What Changed
- Allow a zero reported creation time for process-session directories.
- Keep the probe that rejects a creation time copied from change time.
- Add a regression test that launches and stops a session with zero
birth time.
## Verification
- `npx vitest run
packages/adapter-utils/src/execution-target-stdin-race.test.ts`
- `pnpm --filter @paperclipai/adapter-utils typecheck`
## Risks
A filesystem without creation time can reduce the precision of
sandbox-local path-swap detection. This change does not change host-file
or Paperclip API authority. A follow-up will review that larger security
posture alignment.
> I checked `ROADMAP.md`. This is a focused compatibility bug fix for
the existing sandbox-agent roadmap area.
## Model Used
OpenAI Codex — GPT-5.6. The exact deployment suffix and context-window
size are not exposed. The model used reasoning, shell tools, and code
execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - New organizations create their first agent through the onboarding
wizard
> - The wizard does not show provider sign-in when a host credential is
absent or unknown
> - The create step also gives unclear feedback when the provider needs
authentication
> - This pull request adds a safe auth signal and a provider sign-in
step for sandbox drivers
> - The benefit is a clearer onboarding path with no token or account
data in the signal
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting (server API, shared types, and UI)
**Problem or motivation**
The onboarding wizard can fail when the selected provider needs
authentication. It does not tell the person how to complete sign-in.
**Proposed solution**
Add a status-only provider auth signal. Show the sign-in panel for
sandbox drivers when the signal says `absent` or `unknown`. Apply a
stored Claude login to the new agent and block creation when the adapter
test reports missing authentication.
**Alternatives considered**
The wizard could hide the sign-in panel when the signal read fails. This
would hide a needed action, so this pull request shows the panel when
the signal is unknown.
**Roadmap alignment**
The change supports the roadmap goal for scoped and audited credential
bindings.
**Additional context**
The auth signal returns only `present`, `absent`, or `unknown`. It never
returns a token, identifier, or account name.
## What Changed
- Add `GET /api/companies/:companyId/adapters/:type/auth-signal` with
company and permission checks.
- Add shared auth-signal types and the UI query path.
- Apply a stored Claude login by reference without reading its token.
- Show the provider sign-in panel only for sandbox drivers with
interactive terminal support.
- Block agent creation when the provider test reports missing
authentication.
- Add route, wizard, and end-to-end test coverage.
## Verification
- `pnpm --filter @paperclipai/server test adapter-auth-signal-routes`
passes 50 tests.
- `pnpm --filter @paperclipai/ui test OnboardingWizard` passes 69 tests.
- `pnpm --filter @paperclipai/ui exec tsc --noEmit` exits with code 0.
- The `e2e_shards` lane runs `tests/e2e/onboarding.spec.ts`.
## Risks
The route reads a host-local readiness signal. It returns `unknown` on
read errors and never exposes credential data. The UI may add a sign-in
step when the signal is unavailable.
## Model Used
OpenAI Codex, GPT-5, extended reasoning, tool use, and code execution.
The exact context window was not provided.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - A self-hosted install in `authenticated` mode signs users in with
Better Auth, mounted at `/api/auth` over a hand-written Drizzle
`account` table in `packages/db`
> - Better Auth 1.7.0 added a required `issuer` field to that `account`
model, plus a unique index on `(issuer, accountId)`
> - The dependency bump in #11886 changed only `server/package.json` and
the lockfile, so the Drizzle table never grew the column
> - The Drizzle adapter checks the model against the schema on every
write, so `linkAccount` throws and sign-up answers 500 with an empty
body; a fresh install cannot create its first user, and an upgraded
install locks out every existing user
> - This pull request adds the `issuer` column and its unique index, and
migrates the column in with a backfill that covers every existing row
> - The benefit is that sign-up and sign-in work again, on a new install
and after an upgrade
## Linked Issues or Issue Description
No existing issue. Describing it inline, following
`.github/ISSUE_TEMPLATE/bug_report.yml`.
Refs #11886 (the dependency bump that introduced the required field).
Refs #12269 (an earlier attempt at this fix; its backfill covers only
`provider_id = 'credential'`).
**What happened?**
Sign-up fails on a self-hosted install. `POST /api/auth/sign-up/email`
answers HTTP 500 with a zero-byte body. The server log carries:
```
[Better Auth]: The field "issuer" does not exist in the "account" Drizzle schema.
# SERVER_ERROR: [BetterAuthError: The field "issuer" does not exist in the "account" Drizzle schema.]
```
The request writes the `user` row and then fails on the `account` row.
The address is stuck after that: a second sign-up answers 422
`USER_ALREADY_EXISTS`, sign-in answers 401, and password reset answers
400 `RESET_PASSWORD_DISABLED` because the account that would hold the
password does not exist.
An upgraded install is worse. `sign-in/email` matches the credential
account on `account.issuer === 'local:credential'`. Rows written before
the upgrade have no issuer, so every existing user is locked out.
**Expected behavior**
`POST /api/auth/sign-up/email` answers 2xx and writes both the `user`
row and its credential `account` row. `POST /api/auth/sign-in/email`
then answers 2xx and sets a session cookie. An install that upgrades
keeps its existing users.
**Steps to reproduce**
1. Start a server from `master` with
`PAPERCLIP_DEPLOYMENT_MODE=authenticated` against an empty database.
2. `curl -X POST http://127.0.0.1:<port>/api/auth/sign-up/email -H
'Content-Type: application/json' -H 'Origin: http://127.0.0.1:<port>'
--data
'{"name":"A","email":"a@example.com","password":"a-long-password"}'`
3. The response is HTTP 500 with an empty body.
**Paperclip version or commit**
`master` at 4436cf0. The defect starts at 69e8585 (#11886), which moved
Better Auth from 1.6.28 to 1.7.0.
**Deployment mode**
`authenticated`. `local_trusted` does not sign users in, so it is not
affected. Hosted tenants are not affected either: that path resolves the
actor from a trusted header and never reads `account`.
**Database mode**
Both. Embedded PostgreSQL and external PostgreSQL use the same Drizzle
schema.
**Relevant logs or output**
Reproduced in a test by reverting the schema change:
```
stderr | better-auth-credential-signup.integration.test.ts
[Better Auth]: The field "issuer" does not exist in the "account" Drizzle schema.
AssertionError: expected 500 to be 200
```
## What Changed
- `packages/db/src/schema/auth.ts`: adds `issuer` (text, NOT NULL) to
`authAccounts`, and the `(issuer, account_id)` unique index that mirrors
the index Better Auth declares on the model. The field name, type,
requiredness, and index all come from
`@better-auth/core/dist/db/get-tables.mjs` in 1.7.0.
- `packages/db/src/migrations/0230_better_auth_account_issuer.sql`: adds
the column, backfills every existing row, sets NOT NULL, and creates the
unique index.
- `packages/db/src/migrations/meta/0230_snapshot.json` and
`_journal.json`: regenerated with `pnpm --filter @paperclipai/db
generate`.
- `packages/db/src/better-auth-account-issuer-migration.test.ts`: new.
Asserts the schema shape, then rewinds the migration on a real database,
seeds pre-upgrade rows, and re-applies it.
-
`server/src/__tests__/better-auth-credential-signup.integration.test.ts`:
new. Real sign-up and sign-in through the Better Auth mount, against the
real Drizzle schema and a migrated PostgreSQL.
- `cli/src/__tests__/worktree.test.ts`: the worktree seed fixture writes
a credential `account` row, so it now writes `issuer` too.
`server/package.json` and `pnpm-lock.yaml` are untouched. The dependency
is correct; the schema was what was missing.
### The issuer values, and where they come from
Better Auth builds these itself, in
`@better-auth/core/src/db/schema/account.ts`:
```ts
export function createLocalAccountIssuer(providerId: string): string {
return `local:${encodeURIComponent(providerId)}`;
}
export function createOAuthAccountIssuer(providerId: string): string {
return `local:oauth:${encodeURIComponent(providerId)}`;
}
```
Sign-up and sign-in both call `createLocalAccountIssuer("credential")`,
so a credential account is `local:credential`. An OAuth account whose
provider declares no `accountIssuer` of its own is
`local:oauth:<providerId>` — no built-in social provider declares one.
The migration writes exactly those two forms:
```sql
ALTER TABLE "account" ADD COLUMN IF NOT EXISTS "issuer" text;
UPDATE "account"
SET "issuer" = CASE
WHEN "provider_id" = 'credential' THEN 'local:credential'
ELSE 'local:oauth:' || "provider_id"
END
WHERE "issuer" IS NULL;
ALTER TABLE "account" ALTER COLUMN "issuer" SET NOT NULL;
CREATE UNIQUE INDEX IF NOT EXISTS "account_issuer_account_id_uq" ON "account" USING btree ("issuer","account_id");
```
Two limits are worth stating plainly. The OAuth branch reproduces
`createOAuthAccountIssuer` for provider ids that need no
percent-encoding, which covers every built-in provider id; a provider id
with a character `encodeURIComponent` would escape would get a slightly
different string. And a generic-OAuth provider that sets `accountIssuer`
explicitly (Okta, Auth0, Keycloak, Slack, Line) uses the real issuer
URL, which this migration cannot know. Neither case can arise on
Paperclip today: `createBetterAuthInstance` configures
`emailAndPassword` only and registers no social or generic-OAuth
provider, so every existing row is a credential row. The OAuth branch is
there so the backfill stays total rather than leaving a NULL that aborts
`SET NOT NULL`.
## Verification
- `pnpm --filter @paperclipai/db check:migrations` — passes.
- `pnpm --filter @paperclipai/db typecheck` — passes.
- `packages/db` suite: 30 files, 107 tests, all pass.
- `npx tsc --noEmit` in `server/` — no error in any changed file. (The
wrapped `pnpm typecheck` builds the runner vendor first, which needs
cargo; that toolchain was not available here, so the pre-existing
"cannot find module" errors from the unbuilt workspace packages remain
in the bare run.)
- `node --test scripts/__tests__/run-vitest-stable-shard.test.mjs` —
passes with the new server suite in the file list.
- The two new tests were confirmed to fail without the fix:
- Reverting `packages/db/src/schema/auth.ts` to its `master` content
makes the server test fail with the reported error and `expected 500 to
be 200`.
- Narrowing the backfill to `WHERE "issuer" IS NULL AND "provider_id" =
'credential'` makes the migration test fail with `column "issuer" of
relation "account" contains null values` — the failure mode of #12269.
- End to end against a server built from this branch, started with
`PAPERCLIP_DEPLOYMENT_MODE=authenticated` on embedded PostgreSQL:
- `POST /api/auth/sign-up/email` → 200 with a user and token.
- `POST /api/auth/sign-in/email` → 200 with a session cookie.
- `GET /api/auth/get-session` → 200 with the session.
- The stored row is `issuer = 'local:credential'`, `provider_id =
'credential'`, `account_id = user_id`, and `pg_indexes` lists
`account_issuer_account_id_uq`.
- `scripts/docker-onboard-smoke.sh` was not used as proof: it installs
`paperclipai` from npm inside the container, so it exercises a published
release rather than this branch.
## Risks
- **Migration.** The migration backfills every existing row before `SET
NOT NULL`, so an install that upgrades keeps working and its users keep
signing in. `account` is one row per user per provider, so the
full-table `UPDATE` and the index build are cheap;
`packages/db/src/table-size-estimates.ts` already classes `account` as
small, and `check:migrations` passes with no new safety finding.
- **New unique index.** `(issuer, account_id)` is the key Better Auth
resolves accounts by, so a duplicate would already be a defect. Better
Auth writes one credential account per user keyed on the user id, so the
pair is unique by construction. An install that somehow holds a
duplicate would fail the index build rather than corrupt anything, and
the migration is a single transaction.
- **Orphaned users are not repaired.** An address that hit the broken
window has a `user` row and no `account` row. This migration does not
delete or repair those rows, so that address stays unusable after the
upgrade: sign-up says the user exists, and there is no credential
account to sign in as or reset. Only installs that ran a build
containing #11886 are affected, and the repair — deleting the orphaned
`user` rows — is a judgment call about live data that does not belong in
an automatic migration.
- **Not a behavior change anywhere else.** Only the `account` table
changes. Hosted tenants resolve their actor from a trusted header and
never read it.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter runtime settles each run through a duplex control
channel
> - A lost channel can leave the remote session-close call without a
usable peer
> - The call has no deadline, so run teardown can wait for the full
adapter timeout
> - This pull request skips that remote call after the runtime latches
channel loss
> - The benefit is faster run finalization while the local cleanup
effects remain
## Linked Issues or Issue Description
**What happened?**
The run teardown placed a remote session-close call over a duplex
control channel that the runtime had already latched as lost. The call
blocked until the adapter execution timeout released it.
**Expected behavior**
Run teardown should release the local warm handle and continue when the
duplex control channel has already failed.
**Steps to reproduce**
1. Start an adapter run with the duplex control channel.
2. Latch a channel-loss state before settlement.
3. Use a runtime whose close call never resolves.
4. Confirm that teardown returns without a remote close call.
**Paperclip version or commit**
Commit d966069a78.
**Deployment mode**
Built from source.
**Agent adapter(s) involved**
Not adapter-specific. The change applies to the shared adapter runtime.
**Database mode**
Not database-related.
**Additional context**
Pull request #12373 used a larger approach for the same failure. The
board closed that pull request. This pull request contains the smaller
change.
## What Changed
- Add the required readonly `skipRemoteClose` field to the runtime
settlement plan.
- Set the field from the latched channel-loss state on the turn-finalize
plan.
- Set the field to `false` on every other settlement plan.
- Release the warm handle locally before the `end_session` step returns
without the remote call.
- Add a test that drives the lost-channel path through the settlement
sequence.
## Verification
- `./node_modules/.bin/tsc --noEmit -p packages/adapter-utils`
- `./node_modules/.bin/vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts` passes the new
test. Three existing tests fail on the merge base: two
session-fingerprint tests and one workspace-hints test.
- `./node_modules/.bin/vitest run
packages/adapter-utils/src/acpx-engine/run-fault-matrix.test.ts` reports
20 passed.
- Full CI will run on this pull request.
## Risks
The skipped remote close also skips the vendored runtime caller for
`closeBackendSession`. The run can keep a retained client after duplex
loss. A separate follow-up owns that residual. The environment lease
still releases in the teardown `finally` block.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox providers let agents run in remote environments
> - The Daytona login flow creates a home directory for each login
session
> - The create path ran owner, mode, and link-type checks inside the
sandbox
> - These checks cannot protect the host because sandbox code can change
the checked state
> - This pull request uses one `mkdir -p` command and removes the unused
helper scripts
> - The benefit is a simpler login path with the host-side credential
checks unchanged
## Linked Issues or Issue Description
**What happened?**
The Daytona login flow used helper scripts and inside-sandbox checks for
the session-home directory. The standalone package build also copied a
scripts directory that no longer existed after the helper scripts were
removed.
**Expected behavior**
The login flow must create the session home with one `mkdir -p` command.
The package build must complete without copying a removed directory.
**Steps to reproduce**
1. Build the Daytona plugin package.
2. Start a Daytona device login.
3. Inspect the session-home create command and the package output.
**Paperclip version or commit**
Commit `dfdf5914ba37caa1e3bc380236844a7d76237e12`.
**Deployment mode**
Built from source.
## What Changed
- Replace the session-home helper checks with one `mkdir -p` command.
- Remove the two unused session-home helper scripts.
- Remove the dead build copy steps for the deleted scripts directory.
- Add coverage for a failed session-home create command.
- Keep the host-side credential reader unchanged.
- Keep the Kubernetes provider package unchanged.
## Verification
- Package unit tests pass: 220 passed, 6 skipped.
- Package typecheck passes.
- The package build passes and emits 56 files in `dist`.
- The roadmap check confirms that this change stays within the planned
sandbox-provider work.
- GitHub search found no open duplicate or related pull request.
## Risks
The login flow no longer reports owner, mode, or link-type errors from
inside the sandbox. Those checks did not protect the host. The host-side
credential reader still uses no-follow path opens and accepts only a
regular file with owner and exact mode `0600`. Risk is low because this
change removes checks that cannot enforce the host security boundary.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. This pull request updates an
existing sandbox-provider path, not a new core feature.
## Model Used

The runtime does not expose the context window size or a more specific
model identifier.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox providers run agent work in isolated environments
> - The Daytona inbound file-sync path writes selected sandbox data to
host paths
> - Its in-sandbox lexical and realpath guards do not protect host-write
or Paperclip API authority
> - This pull request removes those guards and simplifies the inbound
file-sync commands
> - The benefit is a smaller path with the same outbound controls and
host extraction validation
## Linked Issues or Issue Description
No public issue exists for this change. This pull request describes the
enhancement.
**What existing behavior does this improve?**
It improves inbound file and directory synchronization for the Daytona
sandbox provider.
**Subsystem affected**
`packages/plugins` — the Daytona sandbox provider.
**Current behavior**
The inbound path checks lexical and realpath confinement inside the
sandbox. It uses file-descriptor-pinned commands for file promotion,
archive extraction, and decompression. These checks do not protect
host-write or Paperclip API authority.
**Proposed behavior**
Remove the inbound lexical and realpath checks. Use `mv -f` for file
mappings, `tar -xf` for directory mappings, and `zstd -d -o` for
decompression. Keep outbound source checks, atomic snapshot downloads,
and tarball member validation.
**Reason and benefit**
The sandbox boundary protects the relevant authorities. The removed
guards run inside that boundary and only produce early errors. The
simpler commands reduce code and preserve the controls that protect the
host boundary.
**Breaking changes**
The inbound path no longer rejects mappings because of sandbox-side
lexical or realpath confinement. Outbound source validation and tarball
member validation remain unchanged.
## What Changed
- Remove lexical and realpath confinement guards from inbound file
mappings, inbound directory mappings, and post-upload command working
directories.
- Replace file-descriptor-pinned promotion with one `mv -f` command per
file mapping.
- Replace file-descriptor-pinned extraction with one `tar -xf` command
per directory mapping.
- Replace retained-descriptor decompression with `zstd -d -o`.
- Keep outbound source guards, atomic snapshot-and-download, and tarball
member validation.
- Update Daytona tests for the new command shapes and remove tests for
the removed rejections.
## Verification
- The author ran the Daytona package test suite: 232 tests passed and 6
tests skipped.
- The author ran the Daytona package typecheck successfully.
- Review the diff and confirm it changes only the three Daytona files
named in this description.
- Confirm the Storybook check may report `SKIPPED` as an expected
repository state.
## Risks
The inbound path now trusts the sandbox boundary for host-write
protection. A later change that gives sandbox code host-write or
Paperclip API authority could require new guards. Outbound source checks
and archive member validation remain in place. No Kubernetes or core
runtime file changes exist.

## Linked Issues or Issue Description
Refs: #10869
**What happened?**
An embedded PostgreSQL test fixture stopped its cluster while database
clients still held open connections. The postgres.js driver then
scheduled a deferred write on a dead connection. The write caused an
unhandled error after the test shard reported success.
**Expected behavior**
The fixture closes all live clients for its cluster before it stops the
embedded PostgreSQL cluster. Tests then finish without a deferred write
on a dead connection.
**Steps to reproduce**
1. Run the database regression test with the embedded PostgreSQL
fixture.
2. Stop the fixture while its database client still has an open
connection.
3. Observe the deferred write and the process exit status.
**Paperclip version or commit**
Branch base: bdd8f1bed. Change head:
93e85d2ba1.
**Deployment mode**
Local dev with the embedded PostgreSQL test fixture.
**Installation method**
Built from source with pnpm.
**Agent adapter(s) involved**
Not adapter-specific. This change covers database test infrastructure.
**Database mode**
Embedded PGlite.
**Additional context**
The change keeps client references weak and keys them by host and port.
It does not retain credentials. It also handles connection URLs that the
driver accepts when the URL parser rejects them.
## What Changed
- Add a registry for live database clients in the database package.
- Close registered clients before the embedded PostgreSQL fixture stops
its cluster.
- Add a regression test for the teardown race.
- Handle driver-compatible URLs that the standard URL parser rejects.
- Add cleanup for the shared route test harness.
## Verification
- Run the full `packages/db` suite.
- Run `tsc --noEmit` in `packages/db`.
- Run the server suite that uses `route-test-harness.ts`.
- Run the teardown regression test five times.
- Confirm that the negative control fails three times.
- Confirm that no shard reports green tests and exits with an error.
## Risks
The registry changes client cleanup for embedded test fixtures. Weak
references limit retained memory in long-lived processes. The registry
uses host and port only, so it does not retain credentials. No
migration, schema, API, telemetry, authentication, or cryptography
change exists.
## Model Used
OpenAI Codex, GPT-5, tool use and code review support, standard
reasoning mode. The implementing engineer supplied the code and
verification results.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip keeps its state in PostgreSQL, and `packages/db` owns that
schema through Drizzle
> - `drizzle-kit generate` writes a new migration by diffing
`packages/db/src/schema/` against the newest snapshot in
`packages/db/src/migrations/meta/`, so the snapshot must describe the
schema that the migrations produce
> - Snapshot `0228` recorded the new `error_count` column on the wrong
table, and snapshot `0229` inherited the error, so the newest snapshot
no longer matched the schema
> - Because of that, `generate` on `master` folded the drift into any
new migration: it emitted an `ADD COLUMN` for a column that migration
`0228` already creates, which fails on a fresh database, plus an
out-of-scope `DROP COLUMN`
> - This pull request moves the column entry to the correct table in
both snapshots and adds a test that repeats the diff `generate` performs
> - The benefit is that the next person who generates a migration gets
only their own change, and CI fails if the snapshot drifts again
## Linked Issues or Issue Description
No existing issue. The description below follows
`.github/ISSUE_TEMPLATE/bug_report.yml`.
**What happened?**
`drizzle-kit generate` on `master` emits a wrong migration. The newest
snapshot, `packages/db/src/migrations/meta/0229_snapshot.json`,
disagrees with the schema in two places. It omits
`issue_question_response_deliveries.error_count`, which
`0228_nasty_grim_reaper.sql` creates. It also carries
`decision_archive_notification_outbox.error_count`, which no migration
ever creates and the Drizzle schema never declared. Snapshot `0228`
introduced both halves of the error: it added the new `error_count`
column to `decision_archive_notification_outbox` instead of the table
that the same migration creates. Snapshot `0229` copied it forward. Any
new migration therefore starts with two statements that do not belong to
it:
```sql
ALTER TABLE "issue_question_response_deliveries" ADD COLUMN "error_count" integer DEFAULT 0 NOT NULL;
ALTER TABLE "decision_archive_notification_outbox" DROP COLUMN "error_count";
```
The `ADD COLUMN` fails on a fresh database, because migration `0228`
already creates that column. The `DROP COLUMN` targets a column that
does not exist on any deployment.
**Expected behavior**
`drizzle-kit generate` reports "No schema changes, nothing to migrate"
on a clean checkout of `master`, and a new migration contains only the
author's own schema change.
**Steps to reproduce**
1. Check out `master` at commit `bc1a21564`.
2. Run `pnpm install`.
3. Run `pnpm --filter @paperclipai/db generate`.
4. Read the emitted `packages/db/src/migrations/0230_*.sql`. It contains
the two statements above, and no schema file was changed.
**Paperclip version or commit**
`master` at `bc1a21564`. The drift entered in #12307 (snapshot `0228`)
and was carried forward by #12291 (snapshot `0229`), which worked around
it by building its snapshot by hand.
**Deployment mode**
Not deployment specific. It affects anyone who generates a migration,
and it affects any fresh database that would later run the bad
migration.
**Database mode**
All PostgreSQL modes: embedded, local Docker, and hosted.
## What Changed
- Moved the `error_count` column entry from
`decision_archive_notification_outbox` to
`issue_question_response_deliveries` in
`packages/db/src/migrations/meta/0228_snapshot.json` and
`packages/db/src/migrations/meta/0229_snapshot.json`. Both files keep
their `id` and `prevId`, so the snapshot chain is unchanged.
- Added `packages/db/src/migration-snapshot-drift.test.ts`. It reads the
newest snapshot named by `_journal.json`, serializes the schema modules
with `generateDrizzleJson`, and asserts that `generateMigration` returns
no statements. This is the same diff that `generate` performs.
- Documented the snapshot rule in `doc/DATABASE.md` under a new
"Migration snapshots" section.
No migration SQL was added, renumbered, or edited. No schema file
changed. The database is correct as it is; only the snapshot was wrong.
Why both snapshots and not only the newest one: `0229` is the file that
`generate` reads, so repairing it is what fixes the bug. `0228` holds
the same error, and `drizzle-kit drop` removes the last migration and
its snapshot, which would promote `0228` back to newest and bring the
drift back. Repairing both removes that trap. Snapshots are never
applied to a database, so neither edit changes any deployment.
## Verification
Commands run from the repository root.
- `pnpm --filter @paperclipai/db generate` — "No schema changes, nothing
to migrate 😴". It writes no SQL file, no snapshot, and no journal entry.
`git status` stays clean. Before the fix, the same command wrote
`0230_fast_caretaker.sql` with the two spurious statements.
- The repaired `0229_snapshot.json` is byte-identical to the snapshot
that a real `generate` run produced, except for the `id` and `prevId`
that keep the chain intact.
- Chain check: the repaired `0228` and `0229` snapshots now differ by
exactly the two columns that
`0229_drop_company_brand_color_and_attachment_max_bytes.sql` drops,
`companies.brand_color` and `companies.attachment_max_bytes`, and by
nothing else.
- Database check: applied all 229 migrations in order to an embedded
PostgreSQL, then compared the live schema with the repaired snapshot.
179 tables and 2687 columns match, with no missing column, no extra
column, and no nullability difference. The same comparison against the
pre-fix snapshot reports exactly two problems: `column only in snapshot:
decision_archive_notification_outbox.error_count` and `column only in
database: issue_question_response_deliveries.error_count`. This harness
was a scratch script and is not part of the pull request.
- `pnpm --filter @paperclipai/db typecheck` — pass. It runs
`check:migrations`, which is `check-migration-numbering` and
`check-migration-safety`.
- `npx vitest run --root packages/db` — 28 files, 102 tests, all pass.
This includes the new test.
- New test, negative case: with the pre-fix `0229_snapshot.json`
restored, `migration-snapshot-drift.test.ts` fails and prints exactly
the two spurious statements, plus the instruction to run `generate`. It
passes on the repaired snapshot. It takes about 1.2 seconds and needs no
database.
- `node scripts/check-forbidden-tokens.mjs` and `node
scripts/check-no-git-push.mjs` — pass.
## Risks
Low risk. A Drizzle snapshot is a build-time record for `drizzle-kit
generate`. It is never applied to a database, so this change cannot
alter any deployment, and no operator action is needed. Databases that
already ran migrations `0228` and `0229` are correct today and stay
correct.
The proof is a clean `generate`: the command that produced the wrong
migration now reports "No schema changes, nothing to migrate" and writes
nothing.
Two smaller notes:
- The new test depends on `drizzle-kit/api`, which is already a dev
dependency of `packages/db`. If a future `drizzle-kit` upgrade changes
that surface, the test fails loudly at import rather than passing
silently.
- The test imports every module in `packages/db/src/schema/`, which is
the same set that `drizzle.config.ts` points the CLI at. It deduplicates
by object identity, because the barrel re-exports the same table objects
and `drizzle-kit` rejects a table it sees twice.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - A company is the top-level container, and the company General page
holds its settings
> - Two of those settings did almost nothing: the brand color only
tinted the generated company icon, and the attachment size limit sat
under the deployment-level `PAPERCLIP_ATTACHMENT_MAX_BYTES` cap that
already bounded every upload
> - A setting that changes one icon hue, and a setting that can only
lower a limit the operator already set, are not worth the page space or
the code that carries them
> - This pull request deletes both settings from the UI, the validators,
the API contract, the server, and the database
> - With the deployment cap as the only limit left, the message a person
sees when an upload is rejected has to name that limit in terms they can
act on, so the raw byte count becomes a human-readable size
> - The benefit is a shorter company General page for every deployment,
one attachment limit instead of two, and less code between an upload and
its ceiling
## Linked Issues or Issue Description
No existing issue. The description below follows
`.github/ISSUE_TEMPLATE/enhancement.yml`.
**What existing behavior does this improve?**
The company General page (`/company/settings`), the `PATCH
/api/companies/{companyId}` and `PATCH
/api/companies/{companyId}/branding` request contracts, and the
attachment upload limit on task, case, and company-import uploads.
**Subsystem affected**
Cross-cutting: `ui/`, `server/`, `packages/shared`, `packages/db`.
**Current behavior**
The company General page shows an "Appearance" section with three
controls: Logo, Brand color, and Attachment size limit. The brand color
is a hex value that feeds one thing — the hue of the generated company
pattern icon. Companies that never set one already get a hue derived
from the company name. The attachment size limit is a per-company byte
count stored on `companies.attachment_max_bytes`. Every upload path
clamps it against the deployment-level `PAPERCLIP_ATTACHMENT_MAX_BYTES`
cap, so the per-company value can only lower a limit the operator
already chose.
**Proposed behavior**
The Appearance section keeps the Logo control only. The company pattern
icon always derives its hue from the company name. Every attachment path
reads the deployment cap directly, so `PAPERCLIP_ATTACHMENT_MAX_BYTES`
is the single limit. An upload rejected by that limit says so in human
units — "File is larger than the 10 MB limit" rather than a raw byte
count. The `companies.brand_color` and `companies.attachment_max_bytes`
columns are dropped, and both fields leave the company API contract.
**Reason and benefit**
Both settings ask an operator to make a decision that changes almost
nothing. The brand color moves one icon hue on a page that also lets you
upload a real logo, which overrides the icon entirely. The attachment
limit reads as a real control but cannot raise anything, so it is a
second place to look when an upload is rejected. Removing both shortens
the page every deployment sees, removes a company-scoped read from the
task attachment upload path, and leaves one attachment limit to reason
about instead of two.
**Breaking changes**
The company API responses no longer include `brandColor` or
`attachmentMaxBytes`, and `GET /api/invites/{token}` no longer includes
`companyBrandColor`. `PATCH /api/companies/{companyId}/branding` is
strict, so a request that sends `brandColor` now returns 400; the
non-strict `PATCH /api/companies/{companyId}` schema strips it. Company
packages exported by older versions still import: the portability
company manifest schema is non-strict, so the retired keys are stripped
and ignored rather than rejected. Companies that stored a brand color
lose it — their icon reverts to the name-derived hue that every company
without a color already used.
## What Changed
- Removed the "Brand color" and "Attachment size limit" fields from the
company General page, along with their state, dirty checks, save
payload, and Save-button gating.
- Removed `brandColor` and `attachmentMaxBytes` from
`createCompanySchema`, `updateCompanySchema`, and
`updateCompanyBrandingSchema`, and deleted the now-orphaned
`DEFAULT_COMPANY_ATTACHMENT_MAX_BYTES` and
`MAX_COMPANY_ATTACHMENT_MAX_BYTES` constants.
- Removed both fields from the `Company` type, the portability manifest
type and schema, and the `companiesApi.update` payload allowlist.
- Dropped `brandColor` from `CompanyPatternIcon` and its callers, so the
icon hue always comes from the company name. Deleted the now-unused
`hexToHue` helper and the now-unused `pickTextColorForSolidBg` export.
- Stopped emitting `brandColor` from the company service selection and
from the invite-summary and invite-branding payloads in
`server/src/routes/access.ts`.
- Replaced `normalizeIssueAttachmentMaxBytes` with the deployment cap:
task attachments, case attachments, and company import now use
`MAX_ATTACHMENT_BYTES` directly. The helper is deleted.
- Added `formatAttachmentSize()` next to `MAX_ATTACHMENT_BYTES` and
routed every over-limit message through it, so a rejected upload names
the limit in human units instead of raw bytes: `Image exceeds 10485760
bytes` becomes `Image is larger than the 10 MB limit`. Enforcement is
unchanged — the same single cap, the same multer limits, the same status
codes and response shapes.
- Added migration
`0229_drop_company_brand_color_and_attachment_max_bytes.sql` and removed
both columns from the Drizzle `companies` schema.
- Kept legacy imports working: the portability company manifest schema
is non-strict, so older packages carrying the retired keys still import
with the keys ignored.
- Updated the skill API reference and the implementation spec, and
pruned the token-extraction allowlist entries that the removed code made
stale.
## Verification
Commands run from the repository root:
- `pnpm --filter @paperclipai/shared typecheck` — pass
- `pnpm --filter @paperclipai/db typecheck` — pass (includes
`check:migrations`, which validates the new migration number and journal
entry)
- `pnpm --filter @paperclipai/ui typecheck` — pass
- server typecheck via `node_modules/.bin/tsc --noEmit` in `server/` —
pass. `pnpm --filter @paperclipai/server typecheck` could not run
locally because it builds the Rust runner first and `cargo` is not
installed on this machine; the TypeScript step it wraps is the command
above.
- `npx vitest run packages/shared/src/validators/company.test.ts` — 6
passed
- `npx vitest run server/src/__tests__/company-portability.test.ts` — 90
passed
- `npx vitest run server/src/__tests__/attachment-types.test.ts
server/src/__tests__/assets.test.ts
server/src/__tests__/issue-attachment-routes.test.ts
server/src/__tests__/company-portability.test.ts
server/src/__tests__/cases-routes.test.ts` — 165 passed (the
human-readable limit messages)
- `npx vitest run server/src/__tests__/company-branding-route.test.ts
server/src/__tests__/issue-attachment-routes.test.ts
server/src/__tests__/invite-summary-route.test.ts
server/src/__tests__/openclaw-invite-prompt-route.test.ts
server/src/__tests__/companies-route-cross-company-authz.test.ts` — all
passed
- `npx vitest run cli/src/__tests__/company.test.ts
cli/src/__tests__/company-delete.test.ts` — 27 passed
- `npx vitest run` in `ui/` — 4425 passed, 1 pre-existing failure
unrelated to this change (`OnboardingWizard.test.tsx` "renders instead
of throwing when the browser denies storage access", which also fails on
`master`)
- `npx vitest run` in `server/` — see the note below
- `node scripts/check-token-gates.mjs` — no new violations; the only
reported violations are the pre-existing `PillGuy.tsx` ones present on
`master`
New tests added:
- `packages/shared/src/validators/company.test.ts` — the create and
update schemas strip the retired keys, the strict branding schema
rejects `brandColor`, and the portability manifest schema accepts a
legacy entry carrying both keys and drops them.
- `server/src/__tests__/company-branding-route.test.ts` — `PATCH
/api/companies/{companyId}/branding` returns 400 for `brandColor` and
does not call the company service.
- `server/src/__tests__/company-portability.test.ts` — a legacy package
that declares `brandColor` and `attachmentMaxBytes` imports
successfully, and neither key reaches `companies.create`.
- `server/src/__tests__/issue-attachment-routes.test.ts` — the effective
task attachment limit is the deployment cap, and the route no longer
loads the company to size an upload.
- `server/src/__tests__/attachment-types.test.ts` —
`formatAttachmentSize()` renders the default cap as `10 MB`, keeps one
decimal place for fractional sizes and drops a trailing `.0`, falls back
to KB and bytes for small caps, steps up to GB, and never emits `NaN`
for a degenerate input.
- `server/src/__tests__/assets.test.ts` — the asset-image and
company-logo routes both return the human-readable limit message on an
over-cap upload.
## Merge with master
`master` moved while this was open, and the merge needed two
resolutions:
- **`ui/src/pages/CompanySettings.tsx`.** #12243 reworded the
user-facing
copy from "company" to "organization", and that rewording landed inside
the "Brand color" and "Attachment size limit" hints — the two fields
this change deletes. Both fields are removed, so the conflicted block is
dropped whole. The Logo field and every other copy change from #12243
are
kept.
- **Migration renumbered 0228 -> 0229.** #12307 landed
`0228_nasty_grim_reaper`, so this migration is now
`0229_drop_company_brand_color_and_attachment_max_bytes`. Its snapshot
is
rebuilt from master's `0228_snapshot.json` with only the two `companies`
columns removed, and `meta/_journal.json` is master's journal plus a
single `idx: 229` entry. `pnpm --filter @paperclipai/db
check:migrations`
passes.
The snapshot was rebuilt by hand rather than taken from `drizzle-kit
generate`, because master's `0228_snapshot.json` has drifted from
master's
own schema: `issue_question_response_deliveries.error_count` is created
by
master's 0228 SQL but missing from its snapshot, and the snapshot still
carries `decision_archive_notification_outbox.error_count`. Regenerating
folds both into this migration, and the resulting `ADD COLUMN
error_count`
would fail on a fresh database where master's 0228 already created that
column. Rebuilding from master's snapshot leaves that drift exactly
where
it is and keeps this migration to the two column drops. The drift is
pre-existing on master and is not addressed here.
## Risks
- **The migration is a destructive column drop.**
`0229_drop_company_brand_color_and_attachment_max_bytes.sql` removes
`companies.brand_color` and `companies.attachment_max_bytes`. It is safe
because both features are removed in the same change and nothing reads
either column after it. The statements use `DROP COLUMN IF EXISTS`,
matching the convention of the recent drop migrations in this
repository. The drop is not reversible: a downgrade after this migration
loses any stored values.
- **Stored brand colors are lost.** A company that had set a color now
renders the name-derived icon hue that every company without a color
already used. No other surface changes, and an uploaded logo still
overrides the icon.
- **API response shape narrows.** `brandColor` and `attachmentMaxBytes`
leave the company payloads, and `companyBrandColor` leaves the invite
summary payload. A client reading those fields now sees `undefined`. The
bundled UI and CLI are updated in this change.
- **Legacy imports are covered.** Packages exported by older versions
still carry both keys. The manifest schema is non-strict, so the keys
are stripped rather than rejected, and a test locks that in.
- **The over-limit message strings changed.** Anything matching on the
old `... exceeds N bytes` text — a test, a script, or a client that
string-matches `body.error` — needs updating. The status codes (422) and
response shapes are unchanged, so structured clients are unaffected.
- **Attachment limits can only widen.** A deployment that had lowered a
company below the deployment cap now allows uploads up to the cap for
that company. Lower `PAPERCLIP_ATTACHMENT_MAX_BYTES` if a smaller
ceiling is needed.
- **Storybook visual baselines shift** for the `CompanyPatternIcon`
matrix story, because those fixtures had brand colors. That workflow
runs only on a PR labeled `storybook-visual`, so it does not gate this
PR; regenerate the baselines if the label is added.

## Linked Issues or Issue Description
No public issue exists; describing the issue inline per the enhancement
template:
**What existing behavior does this improve?**
The instance settings surface — specifically the Settings → Heartbeats
page, which listed scheduler heartbeat agents instance-wide with
enable/disable toggles. The view no longer makes sense as a standalone
settings page: the same controls are available on each agent's
configuration surface, and the instance-wide list framing does not match
how heartbeat agents are managed.
**Subsystem affected**
Cross-cutting: `ui/` (page, route, navigation), `packages/shared`
(settings-visibility registry), docs.
**Current behavior**
The page renders at `/company/settings/instance/heartbeats`, appears in
the settings sidebar and tab bar, and is hideable by hosting operators
via the `instance.heartbeats` key of `PAPERCLIP_HIDDEN_SETTINGS`.
**Proposed behavior**
The page, route, and navigation entries are removed for every
deployment. The `instance.heartbeats` registry key is retired; operator
lists that still send it are logged and ignored, so mixed-version fleets
keep working. Remembered settings paths pointing at the old page remap
to the settings root. Heartbeat APIs are unchanged.
**Reason and benefit**
A smaller, coherent settings surface with no duplicated controls; less
navigation noise and maintenance for every deployment.
**Breaking changes**
None functional. Bookmarks and remembered paths to the removed page land
on the settings root; `PAPERCLIP_HIDDEN_SETTINGS` lists that still
include `instance.heartbeats` log a warning and are otherwise honored
unchanged.
## What Changed
- Deleted `ui/src/pages/InstanceSettings.tsx` (the Heartbeats view) and
its route in `ui/src/App.tsx`.
- Removed the sidebar entry (`CompanySettingsSidebar`) and tab-bar item
(`CompanySettingsNav`).
- Removed `"/heartbeats"` from the remembered-settings-path allowlist;
remembered heartbeats paths now remap to the settings root.
- Retired the `instance.heartbeats` key from the shared
settings-visibility registry and the environment-variables doc;
documented that retired keys are ignored with a warning.
- Dropped the now-unused UI client wrapper for the instance
scheduler-agent list (`heartbeatsApi.listInstanceSchedulerAgents`); the
server endpoint stays.
- Removed the unused `schedulerHeartbeats` query key.
## Verification
- `npx vitest run packages/shared/src/settings-visibility.test.ts
ui/src/lib/instance-settings.test.ts
ui/src/components/CompanySettingsSidebar.test.tsx
ui/src/components/access/CompanySettingsNav.test.tsx` — 24 tests
passing.
- Full `ui` vitest suite: 4426 tests, 4 failures — all in files this PR
does not touch; 3 were load-induced timeouts that pass on rerun, and
`OnboardingWizard.test.tsx` "renders instead of throwing when the
browser denies storage access" fails identically on a clean master
checkout (pre-existing).
- `pnpm --filter @paperclipai/ui typecheck` and `pnpm --filter
@paperclipai/shared typecheck` — clean.
- Merged `master` to clear a conflict (see below) and re-ran the four
focused suites (24 passing), `ui/src/App.test.tsx` and
`ui/src/plugins/bridge.test.ts` (22 passing), and both typechecks — all
clean. Full CI is green on the merge commit.
## Merge With master
`master` gained the `company` → `organization` copy pass (#12243), which
reworded strings inside `ui/src/pages/InstanceSettings.tsx` — the page
this branch deletes — producing a modify/delete conflict. Resolved by
keeping the deletion: the page is going away, so the rewording of its
copy has nothing to apply to. Every other file merged cleanly, and
`master`'s rewording in `App.tsx`, `App.test.tsx`, and
`CompanySettingsSidebar.tsx` sits away from this branch's structural
removals, so both changes survive. The net diff against `master` is
unchanged from the pre-merge review: the same 13 files, 23 insertions,
330 deletions.
## Risks
- Low. Pure removal of a UI surface; heartbeat data and APIs are
untouched. Operators still listing `instance.heartbeats` in
`PAPERCLIP_HIDDEN_SETTINGS` get a warning log and otherwise unchanged
behavior (covered by the registry's unknown-key handling). Bookmarks and
remembered paths to the old page land on the settings root.

## Thinking Path

the settings surface with `PAPERCLIP_HIDDEN_SETTINGS`, but hiding a

hid the control, leaving them no way to answer
> - More generally, operators have no supported way to change what a

settings

with "default the value", while explicit user choices and self-hosted
stock behavior stay untouched
## Linked Issues or Issue Description
No public issue exists; following the enhancement template:
**What existing behavior does this improve?**
Hosting operators need to supply the default value of selected instance
settings (first: `feedbackDataSharingPreference`) via configuration,
without patching code and without a hard-coded, opinionated constant in
the product.
**Subsystem affected**
Server (instance-settings service, feedback service, boot) and
`packages/shared` (settings schemas).
**Current behavior**
Setting defaults are fixed in the shared zod schemas.
`PAPERCLIP_HIDDEN_SETTINGS` can hide the feedback-sharing control and
floor writes, but the stored value stays "prompt", so issue-chat
surfaces keep prompting with no way to answer.
**Proposed behavior**
`PAPERCLIP_SETTING_DEFAULTS` takes a JSON object validated against a
shared registry of defaultable fields. The operator value substitutes
for the schema default at read time: a field whose effective value is
still the schema default resolves to the operator value; an explicit
non-default user choice always wins. Never persisted; unsetting the
variable restores stock behavior. Malformed JSON or an invalid value for
a known field refuses startup (fail closed); unknown field names warn
and are ignored (mixed-version fleet safe).
**Reason and benefit**
Any hosting operator can pair "hide the control" with "default the
value" without forking the product. Explicit user choices and
self-hosted stock behavior stay untouched.
**Breaking changes**
None. With the variable unset, every read path is byte-identical to
before.
## What Changed
- New `packages/shared/src/setting-defaults.ts`:
`SETTING_DEFAULTS_ENV_KEY`, `DEFAULTABLE_GENERAL_SETTINGS` registry
(currently `feedbackDataSharingPreference`), `parseSettingDefaults`
(fail-closed for policy content, warn-ignore unknown fields),
`applyOperatorGeneralDefaults` (pure read-time overlay),
`stripOperatorGeneralEchoes` (persist-time echo strip, see below),
re-exported from the package index.
- New `server/src/services/setting-defaults.ts`: parse-once accessor
mirroring `settings-visibility.ts`.
- `server/src/services/instance-settings.ts`: `toGeneralView` applies
the overlay in `get`/`getGeneral`/update responses; persisted writes
never carry operator values. Because general-settings writes materialize
every field, a stored schema-default value is treated as unchosen —
deliberate, documented, and covered by tests.
- `server/src/services/feedback.ts`: the preference-persistence branch
now checks the effective (overlaid) preference, so a stray prompt answer
cannot overwrite an operator default; its local normalize fallback now
returns full schema defaults.
- `server/src/index.ts`: boot-time fail-fast parse with a log line
naming the defaulted settings, mirroring the managed-config posture.
- The hidden-settings write floor (`assertNoHiddenSettingChanges`) keeps
comparing against effective values, so clients echoing a full GET
response keep working. To keep the overlay strictly read-time,
`updateGeneral` strips such echoes at persist time: a write of the
operator value over a field whose stored value is still the schema
default (unchosen) maps back to the schema default, so an echo cannot
promote the operator value into an explicit stored choice and later
changes to (or removal of) `PAPERCLIP_SETTING_DEFAULTS` still take
effect. A write of any other value, or over an explicit stored choice,
persists as given.
- Docs: `PAPERCLIP_SETTING_DEFAULTS` row + "Operator setting defaults"
section in `docs/deploy/environment-variables.md`.
- Tests: `packages/shared/src/setting-defaults.test.ts` (parse matrix,
overlay precedence, echo-strip matrix, immutability) and
`server/src/__tests__/instance-settings-operator-defaults.test.ts`
(accessor, substitution, explicit-choice wins, unset identity,
never-persisted, full-GET echo stays unchosen, explicit non-default
write persists).
## Verification
- `npx vitest run packages/shared/src/setting-defaults.test.ts
server/src/__tests__/instance-settings-operator-defaults.test.ts
server/src/__tests__/instance-settings-managed-overlay.test.ts` — 33
tests passing.
- `npx vitest run server/src/__tests__/instance-settings-routes.test.ts
server/src/__tests__/instance-settings-service.test.ts` — 57 passing;
`npx vitest run server/src/__tests__/feedback-service.test.ts
server/src/__tests__/issue-feedback-routes.test.ts` — 18 passing.
- `pnpm --filter @paperclipai/shared typecheck` and `pnpm --filter
@paperclipai/server typecheck` — clean.
## Risks
- Low. With the variable unset every read path is byte-identical to
before (identity overlay, covered by tests). The overlay is read-time
only and never persisted, so no migration and no data risk. Fail-closed
parsing means a bad policy value is a loud boot failure rather than
silent drift — consistent with the existing managed-config contract.

## Linked Issues or Issue Description
No public issue exists; following the enhancement template:
**What existing behavior does this improve?**
`PAPERCLIP_HIDDEN_SETTINGS` can hide the whole Secrets page
(`company.secrets`) but not individual tabs. Operators of managed
deployments need to hide the Provider vaults and Proposals tabs while
keeping the rest of the page.
**Subsystem affected**
Settings visibility (`packages/shared/src/settings-visibility.ts`) and
the Secrets page UI (`ui/src/pages/Secrets.tsx`).
**Current behavior**
The Secrets page always renders all four tabs (Secrets, My secrets,
Provider vaults, Proposals), polls pending proposals for the badge, and
offers "manage vaults" affordances that jump to the vaults tab.
**Proposed behavior**
Two new registry keys, `company.secrets.vaults` and
`company.secrets.proposals`, hide the corresponding tab: the tab-bar
entry disappears, an active hidden tab snaps back to Secrets, the
manage-vaults affordances are suppressed, and the pending-proposals poll
stops. UI visibility only — the provider-config and proposal APIs stay
live for agents and integrations, matching the existing `company.*`
precedent. Nothing changes when the variable is unset.
**Reason and benefit**
Any hosting operator (a managed cloud, an internal shared server) can
trim the Secrets page to what fits their deployment — for example when
the operator provisions provider credentials itself, so the vault and
proposal flows do not apply — without losing the Secrets and My secrets
tabs, which stay essential everywhere.
**Breaking changes**
None. With `PAPERCLIP_HIDDEN_SETTINGS` unset (or set to existing keys
only) nothing changes; older app versions receiving the new keys ignore
them with a warning by design.
## What Changed
- `packages/shared/src/settings-visibility.ts`: new
`HIDEABLE_COMPANY_SECTIONS` group (`company.secrets.vaults`,
`company.secrets.proposals`), `HideableCompanySection` type,
`hidesCompanySection()` helper, wired into `HideableSettingKey` /
`HIDEABLE_SETTING_KEYS`, re-exported from the package index.
- `ui/src/pages/Secrets.tsx`: tab-bar filtering, hidden-tab snap-back
effect, gated pending-proposals query, conditional `onManageVaults` on
both the import button and dialog (the button's "AWS vault disabled —
manage" affordance renders nothing when vaults are hidden), hidden
`TabsContent` blocks.
- Docs: new bullet in `docs/deploy/environment-variables.md` under
"Hiding settings surfaces".
- Tests: registry membership/parse cases in
`settings-visibility.test.ts`; new render cases in
`Secrets.render.test.tsx` (hidden tabs absent + proposals poll skipped;
default render keeps both tabs and the poll).
## Verification
- `npx vitest run packages/shared/src/settings-visibility.test.ts
ui/src/pages/Secrets.render.test.tsx` — 43 tests passing.
- `pnpm --filter @paperclipai/shared typecheck` and `pnpm --filter
@paperclipai/ui typecheck` — clean.
## Risks
- Low. Nothing changes with `PAPERCLIP_HIDDEN_SETTINGS` unset (covered
by the default-render test). The keys are UI-visibility only, so
agent/integration API access is unaffected. Older app versions receiving
the new keys ignore them with a warning by design.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Humans oversee those agents in teams, so each person has a login and
a profile with an avatar
> - Avatars, logos and pasted images all go to one asset upload API,
which files each object under a namespace
> - The avatar namespace embeds the user id, and a deployment can take
user ids from an external identity layer, where a subject often holds
":", "|", "." or "@"
> - But the namespace validator accepted only letters, numbers, "/", "_"
and "-", so those users got a 400 "Invalid image metadata" error and
could not set a profile photo
> - This pull request widens the accepted characters, rejects "." and
".." path segments with a clear message, and cleans the namespace in the
upload client
> - The benefit is that profile photo upload works for every user, and a
namespace the API refuses now returns a message that says what is wrong
## Linked Issues or Issue Description
No existing issue or open pull request covers this. I searched the issue
and pull request lists for "avatar upload", "profile photo", "Invalid
image metadata" and "asset namespace" and found no duplicate. The bug
report follows.
**What happened?**
Profile photo upload fails. `ui/src/pages/ProfileSettings.tsx` sends the
namespace `profiles/${user.id}` to `POST
/api/companies/:companyId/assets/images`. When the user id comes from an
external identity layer it can contain ":", "|", "." or "@" — for
example `oidc:example|jane.example@example.com`.
`createAssetImageMetadataSchema` in
`packages/shared/src/validators/asset.ts` accepted only
`/^[a-zA-Z0-9\/_-]+$/`, so the route returned 400 "Invalid image
metadata" (`server/src/routes/assets.ts`). The image bytes were never
the problem, but the message pointed at the image, so the toast gave the
user nothing to act on.
A second case has the same cause. The agent instructions editor in
`ui/src/pages/AgentDetail.tsx` builds a namespace that ends with a
filename, such as `agents/<id>/instructions/SKILL.md`. The "." in the
filename also failed the check.
**Expected behavior**
A profile photo uploads for any user id the app itself issues, and an
image pasted into the agent instructions editor uploads for any
instruction filename. A namespace the API does refuse returns a message
that names the field and states the rule.
**Steps to reproduce**
1. Run Paperclip with an external identity provider, so `user.id` holds
an OIDC subject such as `oidc:example|jane.example@example.com`.
2. Open Settings, then Profile.
3. Choose an avatar image.
4. The upload fails and the page shows "Invalid image metadata".
Or, with no identity provider:
1. Open an agent, then the instructions editor, and select a file whose
name contains a "." such as `SKILL.md`.
2. Paste an image into the editor.
3. The upload fails with the same error.
**Paperclip version or commit**
`master` at eb86fcd49.
**Deployment mode**
Any deployment whose user ids come from an external identity layer. The
instructions-editor case reproduces on a plain self-hosted install too.
**Agent adapter(s) involved**
Not adapter-specific (core bug).
## What Changed
- `packages/shared/src/validators/asset.ts`: widen the namespace pattern
to `/^[a-zA-Z0-9\/_.:@|-]+$/`, and reject any "/"-separated segment
equal to "." or "..". A traversal attempt now gets a clean 400 from the
validator instead of an error from the storage provider.
- `packages/shared/src/validators/asset.ts`: add
`sanitizeAssetNamespace()`, which maps any string to a namespace the
schema accepts. It works per segment: it keeps the accepted characters,
turns the others into "-", collapses repeated dashes, drops empty and
dot-only segments, and caps the result at 120 characters. It returns
`undefined` when no segment survives, and the caller then sends no
namespace.
- `packages/shared/src/validators/asset.ts`: export
`ASSET_NAMESPACE_MAX_LENGTH` and `ASSET_NAMESPACE_RULE`, so the rule
text and the API error cannot drift apart.
- `ui/src/api/assets.ts`: run the namespace through
`sanitizeAssetNamespace()` in `uploadImage`. This is one choke point for
all callers, so no caller has to know the rule.
- `server/src/routes/assets.ts`: name the field in the 400 message —
`Invalid image metadata: "namespace" must be 1-120 characters of
letters, numbers, or / _ - . : @ |, and cannot contain "." or ".." path
segments`. The zod issue details stay in the response. The UI shows
`body.error`, so the toast is now actionable.
- Tests: a new `packages/shared/src/validators/asset.test.ts`
accept/reject matrix for the schema and the sanitizer; three cases in
`server/src/__tests__/assets.test.ts`; one case in
`ui/src/pages/ProfileSettings.test.tsx`.
## Verification
Targeted runs:
```
npx vitest run packages/shared/src/validators/asset.test.ts # 22 passed
npx vitest run server/src/__tests__/assets.test.ts # 11 passed
npx vitest run ui/src/pages/ProfileSettings.test.tsx # 2 passed
```
New cases:
- Schema: accepts identity-provider ids that hold ":", "|", "." and "@";
accepts `agents/<id>/instructions/SKILL.md`; rejects `profiles/bad
name!`, over-length input, and `.` or `..` segments.
- Sanitizer: passes identity-provider ids through unchanged, replaces
and collapses the other characters, drops the `.` and `..` segments
while keeping a segment of three or more dots, caps at 120 characters
without leaving a dot segment behind at the cut, and returns `undefined`
when nothing survives. One case asserts the sanitizer output always
parses.
- Route: 201 for `profiles/oidc:example|jane.example@example.com`, and
the storage service receives that namespace; 400 naming `namespace` for
`profiles/bad name!`; 400 for `profiles/../secrets`.
- UI: a session user id holding ":" and "|" uploads, and the namespace
reaches the API unchanged.
Typecheck:
```
pnpm --filter @paperclipai/shared typecheck # clean
pnpm --filter @paperclipai/ui typecheck # clean
cd server && npx tsc --noEmit -p tsconfig.json # clean
```
Package suites:
```
npx vitest run --project @paperclipai/shared --exclude "**/dist/**" # 586 passed, 8 pre-existing failures in src/worktree-seed-source.test.ts
npx vitest run --project @paperclipai/ui --exclude "**/dist/**" # 4402 passed
```
CI runs the server suite as ten shards (five general, five serialized),
which is the authoritative full run for this package. All shards pass on
this branch.
The `worktree-seed-source` failures reproduce on an unmodified checkout
of the same base commit and are unrelated to this change. The UI
failures seen in that run were 5-second test timeouts caused by running
two suites at once on one machine; each file passes when it runs alone.
No document states the namespace character rule — I checked `docs/` and
`doc/`, where the asset upload endpoint appears only in an OpenAPI
registry entry and a smoke-lab note, neither of which describes the
metadata fields. The rule now lives in one exported constant that the
API error reuses.
## Risks
Low risk.
- The wider character set does not widen what a caller can write to
disk. `server/src/storage/service.ts` already replaces every character
outside `[a-zA-Z0-9._-]` in each path segment, and
`server/src/storage/local-disk-provider.ts` already rejects "." and ".."
segments and any key that resolves outside the base directory. This
change moves the "." and ".." refusal earlier, to the validator, so the
caller gets a clear 400.
- The API is more permissive than before, so no request that used to
succeed can start failing.
- Namespaces stored before this change keep working. The namespace is
not a key that is looked up; it is a prefix under which new objects are
filed.
- One behavior change worth noting: the UI now cleans a namespace
instead of sending it as typed, so a caller that passes an unusable
namespace gets a cleaned prefix rather than a failed upload.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Adapter utilities transfer files between the host and an agent
environment
> - A sandbox target already provides the security boundary for inbound
files
> - The generic fallback adds a temporary file and a rename that do not
add protection inside that boundary
> - This pull request writes a mode-constrained inbound file directly to
its target and applies the mode after the write
> - The benefit is a simpler transfer path while host targets keep the
strict pre-write mode rule
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The inbound file-sync fallback for a mode-constrained file stages the
file under a temporary name, applies the mode, and renames the file into
place.
**Subsystem affected**
`packages/adapter-utils` and `packages/plugins`.
**Current behavior**
A sandbox target uses a temporary path before it receives the file. The
host then changes the mode and renames the file to the target path.
**Proposed behavior**
A sandbox target receives the file at its target path. The host applies
the mode after the write. A host target still applies the mode before
the first byte.
**Reason and benefit**
The sandbox boundary already protects the target. The direct write
removes an unnecessary staging path and rename.
**Breaking changes**
None. The directory path and outbound transfer path keep their existing
behavior.
## What Changed
- Write a mode-constrained single-file inbound transfer directly to the
sandbox target.
- Apply the mode after the direct write and keep the confinement check
before post-upload commands.
- Scope the protocol comment by transfer direction and preserve the
strict host-target rule.
- Keep directory inbound transfers and outbound transfers unchanged.
## Verification
- Run the targeted unit suite for the changed package.
- Verify the suite covers direct target writes, post-write mode
application, and confinement rejection.
- Run `tsc --noEmit` for both changed packages.
- Review the full GitHub Actions check set after the PR opens.
## Risks
- A sandbox provider that assumes a temporary inbound path could expose
a behavior mismatch.
- The confinement check remains before post-upload commands, which
limits escape risk.
- Host targets keep the pre-write mode rule, so host permission behavior
does not change.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents can pause a task and ask the user structured questions.
> - The answer is durable in the issue interaction, but delivery to the
next run is not durable.
> - A process restart can therefore leave an answered interaction
without a continuation attempt.
> - Native runners also need a provider-neutral question contract before
the task page can consume native events safely.
> - This pull request adds a content-free delivery outbox and an
optional native steering seam.
> - Direct adapters keep their existing heartbeat continuation path.
> - The benefit is reliable answer delivery without changing runtime
selection or task-page behavior.
## Linked Issues or Issue Description
Refs #12202. This pull request replaces the question-delivery foundation
from that stale task-thread pull request. The task-thread projection
will follow in a smaller pull request.
**What happened?**
Question answers were stored in the issue interaction. The server then
made one in-memory continuation wake. A server stop between those
operations could leave the answer stored but not delivered. The combined
native task-thread pull request also made this behavior hard to review
separately from UI changes.
**Expected behavior**
The answer and its delivery receipt must commit in one transaction. The
server must retry pending receipts after a restart. Existing direct
adapters must keep the current wake path. A native runtime may use the
optional steering seam, but this pull request does not enable native
steering in production.
**Steps to reproduce**
1. Create an `ask_user_questions` interaction.
2. Answer the interaction.
3. Stop the server before the continuation wake completes.
4. Start the server again.
5. On current master, no durable record tells the server to retry the
answer delivery.
**Paperclip version or commit**
Current `master` at `4d82f5eae`.
## What Changed
- Add the `issue_question_response_deliveries` table and migration.
- Store only routing state, a correlation ID, and a payload digest in
the delivery row. The answer remains in the existing interaction result.
- Commit an answered interaction and its pending delivery row in one
transaction.
- Add bounded claims, retry recovery, cumulative terminal state, and
content-free activity records.
- Keep every built-in direct adapter and external adapter on the
existing heartbeat wake path.
- Add an optional native steering seam. No production caller supplies
that seam in this pull request.
- Retain the provider-neutral `paperclip.question_set.v1` presentation
on recovered interactions.
- Run delivery immediately after an answer and sweep pending rows at
startup and on the existing server interval.
- Add focused database, service, route, startup, adapter-matrix, digest,
and duplicate-delivery tests.
## Compatibility Boundary
- This pull request does not change adapter selection.
- This pull request does not start runnerd.
- This pull request does not create native run records.
- Direct adapters never call the native steering seam.
- The existing interaction result stays authoritative for answer
content.
- The migration is additive and does not rewrite existing rows.
- This pull request has no UI, dependency, workflow, package-manager, or
lockfile changes.
- The diff has 19 files.
## Verification
- `pnpm exec vitest run
server/src/__tests__/question-response-delivery.test.ts
server/src/services/issue-thread-interactions.test.ts
server/src/__tests__/issue-thread-interaction-routes.test.ts
server/src/__tests__/server-startup-feedback-export.test.ts` — 4 files
and 120 tests passed.
- `pnpm -r typecheck` — passed for all applicable workspaces. This
includes Cargo format and check, protocol drift checks, and migration
safety.
- `pnpm build` — passed. This includes the Rust release binary, server
build, and UI production build.
- `git diff --check` — passed.
- Secret patterns were not present in the changed text files.
- The repository token gates currently report violations from unchanged
files on `master`. This pull request does not change those files.
## Risks
The main risk is routing a direct-adapter answer into a native session.
The service checks the persisted runtime mode, and the adapter matrix
proves that all direct adapters use only the existing wake path. The new
table is additive. It has foreign keys, unique correlation constraints,
bounded attempts, and status checks. Activity records omit question and
answer content.

## Linked Issues or Issue Description
**Issue type**
Outdated (no longer matches behavior).
**Where is the issue?**
`packages/plugins/sandbox-providers/SANDBOX-REQUIREMENTS.md` and
`packages/plugins/sandbox-providers/daytona/README.md`.
**What's wrong?**
The Daytona provider no longer uses the documented command wrapper,
package installation commands, or sudoers rule. The requirements
document also lacked a clear statement of the sandbox security boundary.
**Suggested fix**
State that the sandbox provides the boundary. Name outbound workspace
synchronization and the application programming interface bridge as the
paths that cross the boundary. State that a provider must not map a host
path into a sandbox synchronization path.
## What Changed
- Replace stale wrapper requirements with the actual sandbox security
boundary.
- State the controls that apply to outbound workspace synchronization
and the application programming interface bridge.
- State that this repository does not enforce the provider path-mapping
duty today.
- Remove obsolete Daytona package-install commands and the sudoers rule.
## Verification
- Confirm the difference contains the two documentation files and the
test file changed by the follow-up fix.
- Confirm that no unrelated source, configuration, or fixture file
appears in the difference.
- Run the repository continuous integration checks and confirm that
every required check passes.
- Run the repository review bot and confirm its final verdict.
## Risks
Low risk. This pull request changes two documents and closes a database
client in one integration test. It does not change product runtime
behavior or configuration.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox providers transfer files between the host and an agent
sandbox
> - The Daytona file-mapping upload path sends staged tar files without
compression
> - Large raw uploads use more transfer bandwidth and storage
> - This pull request adds transparent zstd-3 compression for eligible
inbound file mappings
> - The benefit is lower transfer size without changes for callers or
post-upload commands
## Linked Issues or Issue Description
**Subsystem affected**
The change affects `packages/plugins`, in the Daytona sandbox provider.
**Problem or motivation**
The Daytona file-mapping upload path sends eligible staged tar files
without compression. This increases transfer size and storage use.
**Proposed solution**
Compress eligible files on the host with zstd level 3. Upload the
compressed bytes to a confined remote scratch path. Decompress them
during the existing promote command, then promote the raw file. Use the
raw upload path when compression cannot run or does not reduce size
enough.
**Alternatives considered**
Keep the raw path for all uploads. This avoids compression work but does
not reduce transfer size. Add a new sandbox round trip for
decompression. This adds latency, so the change uses the existing
promote round trip.
**Roadmap alignment**
`ROADMAP.md` lists Daytona under cloud and sandbox agents. This focused
plugin change does not duplicate a planned core feature.
**Additional context**
The directory-mapping flow stays on the raw path. Callers and
post-upload commands keep the same behavior.
## What Changed
- Add transparent zstd-3 compression to `syncInFileMappings`.
- Upload compressed artifacts to confined remote scratch paths and
decompress them during promotion.
- Keep the raw upload fallback when zstd is absent, compression fails,
or the compressed result does not reduce size enough.
- Create the raw scratch file once with atomic exclusive no-clobber open
and write through the retained descriptor.
- Stage compressed host artifacts in private `0700` directories with
`0600` files.
- Remove temporary directories on success and failure.
- Add regression tests for compressed uploads, fallbacks, decompression
failures, and cleanup.
## Verification
- `pnpm --dir packages/plugins/sandbox-providers/daytona test` passes
with 20 tests.
- The compressed success path produces a byte-identical remote file.
- A target without zstd uses the raw upload path.
- A decompression failure does not promote a partial raw file.
- Temporary files and directories do not remain after success or
failure.
- The newest cleanup regression test fails when the production cleanup
fix is reverted and passes with the fix.
## Risks
- Compression adds host CPU work for eligible file mappings.
- The raw path remains available when compression is unavailable or
ineffective.
- Decompression runs during the existing promote command and can fail
before promotion.
- The change does not alter the directory-mapping flow or caller
interface.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Adapter utilities run process sessions in local and remote
environments.
> - The remote process-session wrapper uses a probe file to verify
directory creation time.
> - A peer could pre-create the probe path or replace it before cleanup.
> - This pull request uses exclusive create and file-descriptor identity
checks to protect the probe.
> - The benefit is safer cleanup and fail-closed behavior at the sandbox
boundary.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The remote process-session wrapper creates and removes a birth-time
probe file. The old path-based flow did not prove that the wrapper
created the path or that the path still named the same file.
**Current behavior**
A sandbox peer can race with the probe path. The peer can pre-create a
symbolic link or replace the probe before cleanup. The wrapper can then
inspect or remove an object that it did not create.
**Proposed behavior**
The wrapper creates the probe with exclusive create. It reads `(dev,
ino, ctimeMs)` from the open file descriptor. It removes the path only
when a final identity read matches the created file.
**Reason and benefit**
This change prevents symlink-following during creation and avoids
removal of a peer's replacement object. The wrapper still fails closed
when it cannot prove a real creation time.
**Breaking changes**
None. The wrapper keeps its existing fail-closed capture behavior.
## What Changed
- Create the birth-time probe with `fs.open(path, "wx")`.
- Read probe identity with `fstat` from the open descriptor.
- Remove the probe only after a matching final identity read.
- Add focused race tests for ordinary cleanup and file, directory, and
symbolic-link replacement.
## Verification
- Run `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit`.
- Run the focused suite
`packages/adapter-utils/src/execution-target-stdin-race.test.ts`.
- Confirm that the focused suite passes all 33 tests.
## Risks
The change affects shared wrapper source for local and remote process
sessions. An identity read or cleanup failure leaves the probe in place
and stops capture. The focused tests cover the new race paths.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution. The model reviewed and

## Thinking Path
> - Paperclip manages AI agents for work.
> - Paperclip includes an observability path that operators can enable
for tracing.
> - The server loads several OpenTelemetry packages only when tracing is
enabled.
> - The documentation calls these packages optional peer dependencies,
but the server manifest does not declare them.
> - This gap hides supported versions and stops Dependabot from
maintaining the packages.
> - This pull request aligns package metadata, runtime checks, and
documentation with the opt-in tracing design.
> - The change gives operators clear installation behavior and keeps the
no-op default.
## Linked Issues or Issue Description
This pull request fixes a package metadata and installation defect.
Related observability work appears in
[#8476](https://github.com/paperclipai/paperclip/pull/8476) and
[#9672](https://github.com/paperclipai/paperclip/pull/9672).
The server documentation described optional OpenTelemetry peer
dependencies, but `server/package.json` did not declare them. Package
managers and Dependabot could not see the supported version ranges. The
UI and Claude local adapter also relied on automatic peer installation
for `yjs` and `@anthropic-ai/sdk`.
The package manifests now declare the optional runtime packages. A
default install does not install optional tracing peers. The server
keeps its no-op behavior when tracing is disabled or a peer is absent.
## What Changed
- Add seven optional OpenTelemetry packages to `server/package.json` and
mark each package as optional.
- Keep `@opentelemetry/api` as a normal dependency for the no-op
interface.
- Disable automatic peer installation in `.npmrc`.
- Declare `yjs` for the UI package and `@anthropic-ai/sdk` for the
Claude local adapter.
- Check declared peer versions before the server loads a dynamic
OpenTelemetry import.
- Keep the endpoint gate, dynamic imports, and fail-open behavior
unchanged.
- Update the observability and README documentation.
- Tell Dependabot that its npm parser does not read `peerDependencies`.
## Verification
- Targeted server tests pass: 34 passed and 2 skipped.
- The skipped tests require the real OpenTelemetry SDK and remain
pre-existing.
- The pull request workflow regenerates the lockfile because manifest
files and `.npmrc` changed.
- The policy job confirms that the pull request does not include
`pnpm-lock.yaml`.
- GitHub checks pass except `security/snyk (cryppadotta)`, which remains
pending after its authorized wait cap.
- Greptile Review reports 5/5 with no open findings.
- Server typecheck passes.
## Risks
- Optional peers can produce a diagnostic when the installed version
does not match the declared range.
- A missing optional peer does not stop the server.
- Disabling automatic peer installation can expose undeclared package
use in other workspaces.
- This pull request declares the affected packages and adds tests for
the changed behavior.
- This pull request makes no database or API changes.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Adapter utilities run remote process-session wrappers for sandbox
work.
> - A wrapper can outlive its host run when the host removes its session
directory during shutdown.

## Linked Issues or Issue Description
Refs: #11916
**What happened?**
Remote process-session wrappers could remain after a host run ended. The
host could remove the session directory before the wrapper read the
shutdown marker. The wrapper then treated directory errors as an empty
queue and continued to poll.
**Expected behavior**
The host must receive an explicit shutdown acknowledgement before it
treats the wrapper as stopped. The wrapper must stop when its session
identity becomes invalid or untrusted.
**Steps to reproduce**
1. Start a remote process-session wrapper.
2. Stop the bridge while the wrapper polls its session directory.
3. Remove the session directory during the poll.
4. Observe that the wrapper must terminate with its child.
**Paperclip version or commit**
`7cfbd1ecbe4a40261ba51fed07f624524352ada2`
**Deployment mode**
Built from source with the adapter-utils test suite.
## What Changed
- Add a shutdown control file and wait for a bounded `shutdownAck`
before session cleanup.
- Require `shutdownAck` as proof of host-side shutdown.
- Capture and verify session and stdin directory identity before each
poll.
- Terminate and latch the wrapper on missing, changed, linked,
non-directory, or untrusted paths.
- Reject unusable creation times and treat all identity-check `lstat`
errors as terminal.
- Add focused regression coverage for shutdown races and identity
failures.
## Verification
- `npx vitest run
packages/adapter-utils/src/execution-target-stdin-race.test.ts` passes.
- The full execution-target set passes: 175 tests across three files.
- The `packages/adapter-utils` typecheck passes with `tsc --noEmit`.
- CI will run on this pull request.
- Greptile will review the pull request.
## Risks
- A platform with unreliable directory creation times can stop a wrapper
earlier than before. This fail-closed result prevents an orphan.
- A transient identity-check error now stops the wrapper. This favors
cleanup over continued polling when the session identity cannot be
trusted.
- Session cleanup remains unconditional after the bounded
acknowledgement wait.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters use SSH environment fixtures to test process behavior
> - The SSH fixture detached its listener process from the test process
> - Teardown removed the fixture directory without stopping and awaiting
that listener
> - This pull request validates fixture state, stops the listener with
bounded escalation, and waits before directory removal
> - The benefit is deterministic test cleanup without orphan listeners
or unsafe signals
## Linked Issues or Issue Description
**What happened?**
The SSH environment fixture detached its listener process. Test teardown
removed the temporary fixture directory without stopping and awaiting
the listener. Repeated test runs left orphan listeners that held
loopback ports.
**Expected behavior**
The fixture teardown stops its listener, waits for exit, and then
removes the fixture directory. A forged state file must not signal an
unrelated process.
**Steps to reproduce**
1. Run the SSH fixture test repeatedly.
2. Inspect listener processes after each run.
3. Observe orphan listeners or ports that remain held.
**Paperclip version or commit**
Commit 324e1331f8.
**Deployment mode**
Not deployment-related.
**Installation method**
Built from source.
**Agent adapter(s) involved**
Custom / external plugin adapter.
**Database mode**
Not database-related.
**Access context**
Unclear / not applicable.
**Node.js version**
Node.js 24.
**Operating system**
Linux.
**Relevant logs or output**
A diagnostic found orphan listeners with parent process ID 1. Each
orphan held a loopback port.
**Relevant config (if applicable)**
Not applicable.
**Additional context**
The change keeps the process identifier reuse check and limits signals
to fixture-owned processes.
## What Changed
- Add one teardown owner for each SSH fixture.
- Stop the detached listener and wait for exit before removing the
fixture root.
- Add bounded SIGTERM and SIGKILL escalation with ESRCH guards.
- Validate the state file before any signal call.
- Require a positive safe-integer PID and safe absolute paths rooted at
the fixture directory.
- Require sshdConfigPath to equal the fixture root sshd_config path.
- Add regression coverage for listener cleanup and forged state files.
## Verification
- `pnpm --filter @paperclipai/adapter-utils typecheck`
- `pnpm exec vitest run packages/adapter-utils/src/ssh-fixture.test.ts`
- Confirm the fixture listener count stays at zero before and after the
test run.
## Risks
The teardown now sends signals to a fixture-owned process. State
validation and the existing PID reuse check limit the target. The
escalation has bounded waits.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The server and the browser need clear error reports when an operator
enables external monitoring.
> - Paperclip already uses an opt-in OpenTelemetry pattern for server
traces.
> - Sentry can provide error reports for both runtime paths when the
operator sets one data source name.
> - This pull request adds one opt-in Sentry gate for the server and the
browser.
> - The benefit is faster diagnosis while the default setup sends no
Sentry data.
## Linked Issues or Issue Description
**What is improved?**
Paperclip gains optional error monitoring for server and browser
failures.
**Subsystem affected**
Cross-cutting (server, UI, and shared authentication data).
**Current behavior**
Paperclip has no built-in Sentry error capture for server failures or
browser boundary failures. Operators must inspect local logs and browser
tools.
**Proposed behavior**
When the operator sets `SENTRY_DSN`, the server and authenticated
browser use the same Sentry project. When the variable is absent, both
paths stay inactive. The server loads Sentry dynamically and fails open
when the optional package is absent.
**Reason and benefit**
Operators can inspect runtime errors in one Sentry project. The default
setup remains local and sends no monitoring data.
**Breaking changes**
None when `SENTRY_DSN` remains unset. Authenticated session responses
add the optional `sentryDsn` field.
**Additional context**
The implementation uses built-in Sentry privacy options. It disables
default HTTP context and breadcrumb integrations and keeps
`sendDefaultPii` false.
## What Changed
- Add an opt-in server Sentry gate with dynamic package loading and
fail-open behavior.
- Add the Sentry data source name to the authenticated session response.
- Add an authenticated browser Sentry gate and React error boundary
capture.
- Add tests for server, browser, route, and application error paths.
- Document activation, installation, privacy settings, capture behavior,
and operator controls.
## Verification
- Run `npx vitest run server/src/__tests__/sentry.test.ts`.
- Run `npx vitest run ui/src/lib/sentry.test.ts`.
- Run `npx vitest run server/src/__tests__/auth-routes.test.ts
server/src/__tests__/shutdown.test.ts`.
- Confirm that the full continuous integration suite passes on this pull
request.
- Leave `SENTRY_DSN` unset and confirm that the server and browser gates
stay inactive.
- Set `SENTRY_DSN` and install the optional Sentry packages before a
manual capture check.
## Risks
The operator controls the Sentry project and accepts the data risk when
the operator enables the feature. Error objects can contain messages,
stacks, or cause chains with private values. The default configuration
sends no data because the feature stays off without `SENTRY_DSN`. A
missing optional server package does not stop server boot.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - #12227 vendored a pnpm patch of the `postgres` driver to stop a
teardown race (`nextWrite` firing after the socket is nulled) from
crashing the process and failing green CI shards
> - Maintainer call: carrying a vendored driver patch is not worth it
for a CI flake — the patch adds a maintenance obligation on every future
driver upgrade
> - The race is an upstream bug in `postgres@3.4.9`; the plan is to wait
for an upstream release that fixes it and bump the dependency instead
> - This pull request reverts #12227 in full: the patch file, its
`package.json` registration, and the regression test that exercised the
patched behavior
> - The benefit is an unmodified dependency graph; the known flake
signature returns and is retried when it bites
## Linked Issues or Issue Description
Reverts #12227.
**What existing behavior does this improve?**
Dependency hygiene: `postgres@3.4.9` is consumed unmodified again, with
no `pnpm.patchedDependencies` entry to re-evaluate on every driver
upgrade.
**Current behavior**
The repo carries `patches/postgres@3.4.9.patch` (null-socket guard in
the driver's deferred write flush, plus an `execute()` refusal on
socketless connections) and a regression test for it.
**Proposed behavior**
Plain upstream `postgres@3.4.9`. The teardown race stays an upstream
bug: a green test shard can occasionally fail with `Vitest caught 1
unhandled error` and `TypeError: Cannot read properties of null (reading
'write')` at `Immediate.nextWrite`; the remedy is retrying the shard
until an upstream driver release fixes the race and we bump.
**Reason and benefit**
A vendored driver patch is a standing maintenance cost that outweighs
the flake it suppressed.
## What Changed
- Reverts #12227 (`6c7c0fd1f`) in full: removes
`patches/postgres@3.4.9.patch`, its `pnpm.patchedDependencies`
registration in root `package.json`, and
`packages/db/src/postgres-driver-teardown.test.ts`. No lockfile
involvement — the merged commit never touched `pnpm-lock.yaml` and the
refresh bot had not yet recorded the patch.
## Verification
- `pnpm install` on the reverted tree is coherent; the full
`packages/db` suite passes (26 files / 100 tests).
- `git revert` applied cleanly with no conflicts.
## Risks
- Low. This restores the exact pre-#12227 state. The known flake
signature returns; it fails jobs whose tests all passed and is cleared
by retrying the shard.
## Model Used
Claude Fable 5 (`claude-fable-5`, Anthropic) via Claude Code — agentic
coding session with tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The server and its test suites talk to PostgreSQL through the
`postgres` (postgres.js) driver, and tests routinely tear their
databases down while connections still carry traffic
> - The driver flushes small buffered frames from a `setImmediate`, and
that deferred flush calls `socket.write()` without checking that the
socket still exists; a reserved connection whose backend died keeps
accepting queries, so the flush can fire with a null socket
> - The resulting `TypeError` escapes from a timer callback with no
try/catch above it, crashing the process — in CI this fails suites whose
tests all passed ("Vitest caught 1 unhandled error"), and the same crash
is reported against the driver in the wild after ECONNRESET
> - The latest driver release (3.4.9) still has the bug, so this pull
request adds a pnpm patch guarding the flush and normalizing timer state
on close, plus a deterministic regression test
> - The benefit is CI that no longer fails randomly on a teardown race,
and production processes that survive a database connection dying at the
wrong moment
## Linked Issues or Issue Description
No public issue exists; the underlying problem follows the bug-report
template.
**What happened?**
CI jobs fail with all tests passing: vitest reports `Vitest caught 1
unhandled error during the test run` with `TypeError: Cannot read
properties of null (reading 'write')` at `postgres/src/connection.js`
`Immediate.nextWrite`. The attribution points at whichever test file
happened to be running (e.g. `native-codex-runner.integration.test.ts`),
because the throw comes from a process-level timer callback, not from a
test. The identical crash is reported against the upstream driver by
other projects after `ECONNRESET` (e.g. immich-app/immich#25098).
**Expected behavior**
A connection dying between a write being scheduled and its deferred
flush must settle the affected queries through the driver's normal
connection-error path, never throw from a bare timer callback.
**Steps to reproduce**
Run the new `packages/db/src/postgres-driver-teardown.test.ts` with the
patch removed: reserve a connection (`sql.reserve()` — the same surface
`sql.begin()` uses), destroy the backend socket, wait for the client to
process the close, then issue one query on the reserved connection. The
deferred flush fires one tick later with `socket === null` and crashes
the process with exactly the CI signature.
**Paperclip version or commit**
master `198fc8b28`, `postgres@3.4.9` (latest release; bug still present
on the driver's master branch).
## What Changed
- `patches/postgres@3.4.9.patch` (new, wired via
`pnpm.patchedDependencies`): `nextWrite` returns without writing when
`socket === null`, dropping the buffered bytes — the close path has
already settled every in-flight query, so those bytes have nowhere to
go. The `closed()` and `terminate()` handlers additionally reset
`nextWriteTimer`/`chunk` after `clearImmediate`, so a stale cleared
handle cannot silently block a future reconnect's first flush. All three
shipped builds (`src`, `cjs`, `cf`) get the identical change.
- `packages/db/src/postgres-driver-teardown.test.ts` (new):
deterministic reproduction against a minimal in-process fake wire server
(startup auth + an empty result for the `fetch_types` bootstrap).
Asserts the late query settles with `CONNECTION_DESTROYED` through
`sql.end()` instead of crashing the process.
## Verification
- The regression test fails against unpatched `postgres@3.4.9` with the
exact CI signature (verified by running the same scenario against an
unpatched checkout) and passes with the patch.
- Full `packages/db` suite: 27 files / 101 tests pass.
- Spot-checked server suites that exercise the database through the
patched driver.
## Risks
- Low. The behavioral change activates only in a state that previously
crashed the process (write flush with no socket). Dropping the buffered
bytes matches what the connection's close path already promised callers:
every in-flight query has been settled with a connection error.
- The timer/chunk reset in `closed()`/`terminate()` prevents a
theoretical stale-handle hang after reconnect; on the normal path both
were already reset by `nextWrite`.
- The patch pins to `postgres@3.4.9`; a future driver upgrade will
surface the patch for re-evaluation (pnpm fails loudly on version
mismatch), and the guard can be dropped if the fix lands upstream.
## Model Used
Claude Fable 5 (`claude-fable-5`, Anthropic) via Claude Code — agentic
coding session with tool use (driver source analysis, wire-protocol fake
server, local test execution).
