and managed-provider control plane.
> - The restored system needs repeatable full-stack checks before it can
ship safely.

decisions.
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting. This change covers runner tests, release workflows,
server contracts, and evaluation tools.
**Problem or motivation**
The runner stack did not have one complete acceptance surface for native
Codex, ACPX, Claude Managed, and AWS AgentCore. Release checks could
miss provider drift, task-view regressions, cost-policy errors, and
destructive cleanup errors.
**Proposed solution**
Add a 57-cell full-stack catalog, a Daytona image, and opt-in paid
workflows. Add live evaluation, chaos, cost-limit, redaction, and
release contract checks. Add AWS AgentCore infrastructure and guarded
provisioning tools. Keep the native runner experimental flag off by
default.
**Alternatives considered**
We considered manual smoke tests only. They do not give repeatable
evidence and they do not protect release branches. We also considered
one large pull request. The stacked pull requests keep each review below
the Greptile file limit.
**Roadmap alignment**
This work supports the shipped Cloud / Sandbox agents milestone and the
shipped Agent evals & feedback milestone in `ROADMAP.md`.
Related stack:
- #12699 adds managed provider backends and lifecycle support.
- #12691 adds qualified OpenCode and ACPX provider backends.
- #12685 restores task runtime rendering and steering.
## What Changed
- Add the runner full-stack harness with 57 catalog cells and 60 unit
tests.
- Add a Daytona runner image with digest-pinned base images and
base-aware image-content checks.
- Add guarded live evaluation and chaos workflows with a fixed
40-execution matrix; live and full-stack paid schedules now run only on
Sundays or by manual dispatch.
- Add in-flight reported-usage cost stops, post-turn cost caps,
exact-threshold failure classification, secret redaction, retry
classification, and actor authorization.
- Reattach stream and hard-budget listeners before restart-recovery
continuations so restored paid sessions cannot bypass in-flight
interruption.
- Preserve OpenCode usage and cost across tool-loop messages and turns
while exposing an explicit current-run delta to durable accounting.
- Keep PNG/WebM evidence in access-controlled artifacts only, reject
SVG, and publish only pruned inert structured per-attempt evidence.
- Add AWS AgentCore infrastructure, provisioning checks, and smoke
tools; reject unsafe model identifiers, require exact stack ownership
markers, and make failed-stack replacement explicit.
- Add evaluation-session contracts and capability reports.
- Add release workflow checks for immutable action pins, frozen
dependency installs, exact weekly cron shape, paid-run guards,
provider-secret isolation, and chaos test paths.
- Reauthorize the original and triggering numeric actor IDs as the first
step of every provider-secret job, including partial reruns, before
checkout or provider access.
- Give each full-stack matrix cell only its matching provider
credential, expose Daytona only to Daytona cells, and disable shared
dependency caches anywhere paid credentials or OIDC write access are
present.
- Protect the legacy manual E2E workflow with the same default-branch,
allowlist, environment, and per-job authorization boundary.
- Rotate live-eval candidates by week and retain 120 days of compatible
history so the seven-week trend window remains viable.
- Restore the root runner-acceptance commands and reconcile reported
snapshots,
raw receipts, and terminal usage without double counting or losing late
usage.
- Mark ACPX token deltas exact only when every budget field is present,
keep
cumulative cost/request authority separate, reject non-USD cost
labeling,
and include thought tokens in output-token budgets.
- Keep `enableNativeRunner` off by default. The acceptance harness
enables it only in its isolated test instance.

- The rebased PR changes 92 files. `pnpm-lock.yaml` is unchanged.
I did not run paid live provider jobs or provision AWS resources. Those
checks need credentials and can create cost.
## Risks
The paid workflows can create provider cost. They require an allowlisted
original and triggering actor, the protected `runner-e2e-paid`
environment, explicit opt-in variables, and cost limits. The four
provider credentials exist only in that master-only environment, which
requires allowlisted reviewer approval and disables administrator
bypass; repository and organization Actions scopes contain no copies.
Provider usage arrives after a billable request, so the live guard
cannot prevent one request from crossing a threshold. It interrupts
immediately on the first reported threshold hit and permits no
continuation.
Visual evidence can contain secrets rendered as pixels. PNG/WebM remain
only in access-controlled workflow artifacts; SVG and per-attempt XML
are excluded, and S3/Pages receive a pruned structured dashboard.
The AWS scripts can create cloud resources. They use explicit commands,
least-privilege roles, KMS encryption, saved nonsecret metadata, and
explicit teardown.
This pull request does not enable the experimental native runner for
existing instances.

## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting: Runner, server orchestration, database profiles, CLI, and
adapter configuration UI.
**Problem or motivation**
The current Runner stack cannot select or execute the managed Claude
Agents API or AWS Bedrock AgentCore Harness backends. It also lacks
qualified profile storage and recovery checks for those remote
resources.
**Proposed solution**
Add qualified managed and remote profiles, API and CLI management, exact
provider selection, durable lifecycle handling, cumulative usage
accounting, bounded cleanup, and retention acknowledgement. Keep
`enableNativeRunner` default-off.
**Alternatives considered**
A direct copy of the old integration branch was rejected because its
provider contracts, model values, credential flow, and migration history
no longer match the current base. A single large parity pull request was
also rejected because stacked review keeps each subsystem bounded.
**Roadmap alignment**
This continues the existing Runner architecture and rollout work. It
does not introduce a separate execution system.
**Additional context**
This pull request is based on the merged #12691 and #12685 stack. It
also closes the delayed security-review findings reported on #12691 by
binding qualified ACPX and OpenCode launch artifacts to the bytes
actually executed. A GitHub search for managed agent, AgentCore, and
Claude managed work found no duplicate public issue or pull request.
## What Changed
- Add Claude Managed Agents and AWS AgentCore provider executors to
runnerd.
- Add qualified managed and remote profile storage, routes, OpenAPI
contracts, CLI commands, and migration 0237.
- Validate profile ownership, enabled state, exact qualified revision,
model, agent version, and secret binding before persistence and
recovery.
- Persist durable provider session and owned skill state for
restart-safe cleanup.
- Reconcile uncertain create responses and delete remote sessions before
owned skills.
- Track cumulative provider usage and enforce positive session spend
caps.
- Recover interrupted AgentCore usage at the next turn boundary by
charging the prior invocation ceiling exactly once; keep the session
gated until an explicit monotonic budget raise.
- Isolate AgentCore AWS configuration from host profiles and
credential-process/SSO configuration while preserving workload identity.
- Require OpenCode 1.18.17 and fixed build-owned provider-pack artifact
paths; remove the ambient executable override.
- Snapshot and content-verify ACPX and OpenCode commands, scripts, and
provider executables before launch. Linux executes sealed inherited
descriptors; macOS uses authenticated private snapshots with retry-safe
rematerialization at the spawn boundary.
- Persist canonical ACPX and OpenCode launch-profile digests, reject
drift across fresh recovery, and make recovery failures sticky.
- Close and journal unsafe ACPX active-turn recovery before any provider
bootstrap or reconnect.
- Add managed provider fields to the Runner configuration UI and
permission projection.
- Preserve the default-off `enableNativeRunner` experimental flag.
## Verification
- `pnpm -r typecheck`
- `pnpm build`
- Focused managed server, database, CLI, Runner TypeScript, Rust,
Claude, AgentCore, ACPX, OpenCode, process-supervisor, and
durable-recovery tests passed.
- `cargo test -p paperclip-runner-core --lib --locked` (160 tests)
- `cargo check --workspace --all-targets --locked`
- Native Codex integration tests passed (60 tests); native provider
tests passed (7 tests); server native-runtime tests passed (87 tests).
- Verified-launch replacement, nested-spawn retry, exact-version,
profile-drift, sticky-failure, and no-bootstrap active-recovery tests
passed.
- `git diff --check`
- The PR changes 91 files. `pnpm-lock.yaml` is unchanged. The Rust
workspace lockfile adds the approved `rustix` dependency used for safe
descriptor handling while `#![forbid(unsafe_code)]` remains enabled.
## Risks
- The provider APIs can change while they are in beta. Exact
qualification and fail-closed recovery checks limit drift.
- Remote cleanup can fail after a partial create. Durable ownership
inventories and retry-safe deletion preserve recovery state.
- Migration 0237 adds profile tables. The generated migration and
snapshot pass the repository migration checks.
- Managed execution can incur provider cost. Positive default spend caps
and explicit retention acknowledgement limit accidental use.
- An interrupted AgentCore invocation without final metadata is
conservatively charged to its active session ceiling. This can overstate
cost, but cannot undercount it; later work requires an explicit budget
increase.
- Linux qualified launches use sealed memory descriptors. macOS lacks
executable-descriptor APIs, so the runner uses owner-only private
snapshots and minimizes linked-path lifetime; hostile same-UID processes
remain outside the documented local-host trust boundary.
- The global Runner feature remains default-off.

## Linked Issues or Issue Description
Refs #12685
**Subsystem affected**
This change affects the runner package, server orchestration, adapter
configuration, and UI configuration.
**Problem or motivation**
Paperclip Runner stores provider contracts for OpenCode and ACPX. New
agents cannot select those providers. Runnerd cannot execute those
stored provider descriptors. The UI also shows only Codex.
**Proposed solution**
Accept the qualified OpenCode 1.18.17 profile and the fixed ACPX Claude
and Codex profiles. Route them through runnerd. Keep provider selection,
model selection, permissions, credentials, events, and recovery inside
closed provider-specific boundaries.
**Alternatives considered**
One option was to keep the contracts dormant. That option leaves stored
configuration and runtime behavior out of sync. Another option was to
enable every ACPX agent. That option is not safe because Pi does not yet
have the same verified launch path.
**Roadmap alignment**
This change supports the completed cloud and sandbox agent milestone. It
also supports self-healing runs and governed agent execution. It does
not add a new roadmap surface.
## What Changed
- Add one server profile resolver for Codex, OpenCode, and qualified
ACPX descriptors.
- Keep `adapterConfig` as the provider and permission authority for
fresh runs.
- Add Paperclip Runner provider, ACPX agent, and provider-specific
permission controls to the UI.
- Reset the model to a compatible qualified value when the provider
changes.
- Route Codex, OpenCode, and ACPX through the durable runnerd provider
selector.
- Add a durable ACPX executor with bounded state, recovery, events, tool
receipts, and identity checks.
- Remove Codex labels from OpenCode events, results, evidence, and
recovery diagnostics.
- Pass only provider-specific credential names to child processes.
- Keep ACPX Pi unavailable and reject it before process launch.
- Keep the existing Paperclip Runner experimental flag unchanged.
## Verification

## Risks
- This changes provider process selection and durable recovery. The
experimental flag still gates every fresh Paperclip Runner run.
- OpenCode requires a model in `provider/model` form and stays pinned to
version 1.18.17.
- ACPX accepts only exact Claude and Codex profile versions and models.
Pi stays unavailable.
- ACPX steering stays unavailable and reports that limit through the
driver capabilities.
- Child processes receive explicit environment allowlists. They do not
inherit the full server environment.
- This pull request has no database migration.

## Linked Issues or Issue Description
Refs: #12618
**Agent or provider**
Grok local adapter.
**Why this adapter is useful**
A remote Grok run can refresh its access token during a run. Copying the
refreshed credential back to the host keeps later runs ready to use.
**How the agent is invoked**
Paperclip invokes the Grok local adapter through its remote subscription
run path. The adapter stages the company Grok home as a sandbox asset.
The change adds a copy-out step on the teardown path.
## What Changed
- `grok-auth-merge-decision.cjs` adds a host predicate in its own
process. It compares the whole `<issuer>::<uuid>` identity key of the
two files. It reads `expires_at` as an ISO-8601 string, an epoch-seconds
number, or an epoch-milliseconds number. It exits 10 to use the source,
20 to keep the destination, 21 when the expiry shape is unreadable, and
22 when the source expiry sits more than 400 days after the host clock.
It fails closed in every unclear case: an unusable side, a different
identity, an absent expiry, a tie, an unreadable expiry, and an
implausible expiry all keep the destination.
- `grok-auth-merge-decision.ts` adds a wrapper that runs the predicate
and maps the exit code to a typed result.
- `grok-auth-copyback.ts` adds `copyBackGrokAuth({ hostHomeDir,
readSandboxAuth, log, env })`. It locks on `hostHomeDir` with
`withDirectoryMergeLock`, stages the sandbox bytes into a private `0600`
temporary file, runs the predicate, and installs the file with an atomic
rename in the same directory. It keeps no backup of the displaced
credential. It leaves no temporary file on the success path, the keep
path, or an error path. On an error it logs the `errno` code only, then
re-throws.
- `execute.ts` adds a `restore` callback to the Grok `home` asset. The
callback takes the destination from
`resolveManagedGrokHomeDir(process.env, agent.companyId)`, never from
`env.GROK_HOME`. A copy-out failure does not fail the run.
- `package.json` updates the `build` script to copy
`grok-auth-merge-decision.cjs` into `dist/server/`, because `tsc` does
not copy a `.cjs` file.
**The credential shape this predicate reads**
A redacted sample of a real vendor credential answered four structural
questions. The answers hold no credential bytes, no account identifier,
no file path, and no timestamp value.
1. `expires_at` is present.
2. `expires_at` sits inside the value object, under the
`<issuer>::<uuid>` key. It is not a top-level field.
3. `expires_at` is an ISO-8601 string. It carries UTC time with a
trailing `Z` and six fractional-second digits.
4. A normal run rewrites `auth.json`. The value object carries a
`refresh_token` next to `expires_at`, so the client refreshes the access
token and rewrites the file.
## Verification
- [x] `pnpm vitest run packages/adapters/grok-local` — 114 tests in 12
files pass.
- [x] `pnpm --filter @paperclipai/adapter-grok-local typecheck` — clean.
- [x] `pnpm --filter @paperclipai/adapter-grok-local build` — succeeds,
and `dist/server/grok-auth-merge-decision.cjs` exists after the build.
- [x] Continuous integration is green on every check.
## Risks
The predicate keeps the host credential when identity, expiry, file
access, or freshness data is unclear. The copy-out path can log an error
and leave the run successful when it cannot install the refreshed
credential. The atomic rename and directory lock protect the host file
from partial writes and concurrent copy-out actions.
## Model Used
OpenAI GPT-5, current deployment. The exact runtime version and context
window are not exposed to this agent. The model used tool calls and code
inspection.

## Thinking Path
> - Paperclip manages agents that use different model providers and
adapters.
> - Paperclip must keep agent execution rules clear and predictable.
> - The cheap-model profile added a second execution mode across
adapters, task recovery, APIs, and the UI.
> - That mode increased configuration and recovery complexity.
> - This pull request removes the cheap-model profile as a product
feature.
> - The benefit is one model-selection path for normal work and recovery
work.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
This change simplifies model selection across agent configuration, task
execution, recovery, and adapter capabilities.
**Current behavior**
Paperclip exposes cheap-model profiles in adapter metadata, agent
runtime configuration, task overrides, recovery rules, APIs, and the
board UI. Recovery work can select a different model profile from the
agent's configured model.
**Proposed behavior**
Paperclip uses the agent's configured model for normal work and recovery
work. Status-only recovery stays limited to coordination work. The API
rejects legacy model-profile configuration. A migration removes stored
model-profile values from existing agent, issue, and historical revision
records.
**Reason and benefit**
One model path reduces configuration, API, UI, and recovery complexity.
It also prevents status recovery from becoming a separate product-level
model-routing feature.
**Breaking changes**
This change removes model-profile fields and adapter capability
metadata. Existing stored model-profile values are removed by an
idempotent migration. The validators reject new legacy profile values
with clear errors.
## What Changed
- Removed model-profile types, adapter capabilities, API fields, and
model selection logic.
- Removed cheap-model controls from agent and task UI surfaces.
- Kept status-only recovery limited to coordination context while normal
continuations use the configured agent model.
- Added an idempotent migration that removes stored model-profile values
from agents, issues, and configuration revisions without changing issue
update timestamps.
- Updated tests and product documentation for the single-model behavior.
## Verification
- `pnpm check:token-gates` passes.
- `pnpm -r typecheck` passes.
- `pnpm build` passes.
- `pnpm test:run` completed with 5,607 passing tests and 8
environment-sensitive failures in unrelated fixed-port and
database-deadlock suites. The same failures repeated in an isolated
rerun. CI is the final clean-room result.
## Risks
- This is an intentional breaking change for clients that send
model-profile fields.
- The migration changes legacy agent, issue, and configuration-revision
JSON. It is idempotent and preserves unrelated fields and issue update
timestamps.
- The change is cross-cutting because the removed feature existed in
adapters, shared contracts, the server, plugins, and the UI.

## Linked Issues or Issue Description
**What existing behavior does this improve?**
This improves the instance experimental settings page, task watchdog
controls, dependency wake recovery, and execution workspace routes.
**Current behavior**
The settings page shows old recovery controls and mixes product
experiments with internal developer settings. Task watchdogs require an
extra feature flag. Some direct workspace links use the current company
prefix instead of the company that owns the workspace.
**Proposed behavior**
Remove the old task recovery experiment and its unused API surface. Make
task watchdog controls available without the removed flag. Put worktree
execution and managed environment controls in the developer section.
Resolve direct workspace links from the workspace owner and reject a
company prefix that does not own the workspace.
**Reason and benefit**
The smaller settings page is easier to understand. The server keeps only
the dependency wake backstop that it still uses. Workspace links open
under the correct company route.
**Breaking changes**
This removes the experimental issue graph recovery preview and run
endpoints. It also removes the task watchdog feature flag. Task watchdog
data and dependency wake behavior remain available.
## What Changed
- Removed the old task watchdog and issue graph recovery feature flags.
- Removed the old issue graph recovery preview, run controls, API
contracts, and unused recovery implementation.
- Kept resolved dependency wakes as the scheduler backstop.
- Grouped product experiments and Paperclip developer settings on the
instance settings page.
- Made task watchdog controls available without an extra experimental
flag.
- Added owner-aware redirects and company checks for execution workspace
routes.
- Hid the false stopped-state badge while a workspace has no active
runtime state.
- Updated focused server and UI tests for the new behavior.
## Verification
- `pnpm check:token-gates`
- `pnpm -r typecheck`
- `pnpm build`
- `pnpm test:run` completed with 5,620 passing tests and four failures
in unchanged workspace runtime port tests. The same four failures repeat
when the two files run alone.
- The complete GitHub CI matrix passed, including all server, serialized
server, build, canary, and end-to-end jobs.
## Risks
- Clients that call the removed experimental recovery endpoints must
stop calling them.
- The route checks depend on workspace detail access. An unknown or
cross-company workspace returns the global not-found page.
- There are no database migrations, lockfile changes, workflow changes,
or design image changes.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Paperclip Runner package manages live sessions and durable
command recovery
> - Capability live-session tests can fail when a turn-timeout rejection
has no handler
> - A resumed session can also stall when the durable control plane
rejects an indeterminate command result
> - These failures make valid tests fail or hide the turn that stalled
> - This pull request captures timeout rejections early and accepts
indeterminate recovered commands
> - The benefit is stable tests and clearer timeout failures after a
runner restart
## Linked Issues or Issue Description
**What happened?**
Capability live-session tests failed intermittently on loaded CI hosts.
A timer could reject a turn promise before the test attached its
assertion. A resumed session could also stall after a runner restart
because the durable control plane rejected the indeterminate command
status.
**Expected behavior**
The test must handle a timeout rejection at promise creation. The
durable control plane must accept an indeterminate recovered command and
allow the session to continue. A configured timeout must persist in the
checkpoint and identify the stalled turn.
**Steps to reproduce**
1. Run the capability live-session test file on a loaded host.
2. Create a turn promise with a timeout and delay before attaching its
assertion.
3. Resume a session after a runner restart with a journaled but
unconfirmed command.
4. Observe the unhandled rejection or the stalled resumed session.
**Paperclip version or commit**
Commit `ede642e57e22ea3fb0a73590fca8bcc994f1a47f` on `master`.
**Deployment mode**
Built from source.
**Installation method**
Built from source.
**Agent adapter(s) involved**
Not adapter-specific. The tests use the Paperclip Runner package.
**Database mode**
Not database-related.
**Additional context**
Pull request #12646 also updates durable recovery for indeterminate
command results. If it lands first, this pull request must retain the
compatible behavior without duplicate edits.
## What Changed
- Add a helper that captures a turn rejection before any await step.
- Update three live-session test sites to assert the captured rejection
value.
- Add a helper test that waits past the turn timeout before it asserts.
- Accept indeterminate as a terminal recovered-command status.
- Add tests for acceptance, duplicate absorption, and reload from
persisted state.
- Add an optional turnTimeoutMs value to resume and pin its checkpoint
behavior.
## Verification
- `npx vitest run src/live/live-session.test.ts` from
`packages/paperclip-runner`: 19 passed, 1 skipped.
- `npx vitest run src/control-plane/durable-prp-control-plane.test.ts`
from `packages/paperclip-runner`: 5 passed.
- The live-session file passed 10 of 10 runs with 30 competing workers
on a 32-core host.
- TypeScript reported five pre-existing errors in
`src/eval/workflow-harness.ts`.
- CI must run `pnpm --filter @paperclipai/paperclip-runner check:all`.
## Risks
The durable control plane now accepts one additional terminal recovery
status. The change affects only recovered command handling and
capability live-session tests. The main risk is overlap with pull
request #12646 if that pull request lands first.
## Model Used
OpenAI Codex, GPT-5, with tool use and code execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip reports server and browser errors through optional Sentry
monitoring
> - One environment variable sends both error types to one Sentry
project
> - Operators need separate control for browser and server error data
> - This pull request adds specific variables and keeps the existing
variable as a fallback
> - The benefit is separate monitoring without breaking current
deployments
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The Sentry configuration for server and browser monitoring uses one
environment variable.
**Subsystem affected**
Cross-cutting (multiple of the above)
**Current behavior**
`SENTRY_DSN` supplies the server and browser clients. Both clients
therefore report to the same Sentry project.
**Proposed behavior**
`SENTRY_DSN_FRONTEND` supplies the browser client. `SENTRY_DSN_BACKEND`
supplies the server process. `SENTRY_DSN` remains a fallback for either
component.
**Reason and benefit**
Operators can send browser and server errors to separate Sentry
projects. Operators can also activate only one component.
**Breaking changes**
None. Existing deployments can continue to use `SENTRY_DSN`.
## What Changed
- Add `resolveSentryDsns(env)` and use it in the server and browser
configuration paths.
- Add precedence, empty-string, fallback, and route tests.
- Update the README, observability guide, and stale code comments.
- Log one warning when the server uses the legacy fallback without
exposing a DSN value.
## Verification
- `pnpm vitest run --project server sentry-dsn` — 8 tests pass.
- `pnpm vitest run --project server auth-routes` — 21 tests pass.
- The earlier run of the three targeted suites passed 40 tests.
- `tsc --noEmit` passes for the files in this diff.
- All required GitHub Actions checks pass, including the full
continuous-integration suite.
## Risks
The main risk is an incorrect environment variable precedence rule. Unit
tests cover specific values, empty strings, and legacy fallback
behavior. The existing `SENTRY_DSN` path remains compatible.
## Model Used
OpenAI Codex — GPT-5, current runtime, tool use and code execution.

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

> - A remote Grok subscription run needs its credential file inside the
sandbox.
> - The adapter did not stage the Grok home, so the sandbox had no

## Linked Issues or Issue Description
**What happened?**
A remote Grok subscription run had no credential file in its sandbox.
The adapter sent no Grok home asset.
**Expected behavior**
The adapter should stage the allowed Grok credential file and set
`GROK_HOME` to the reported sandbox path.
**Steps to reproduce**
1. Start a remote Grok run in subscription mode.
2. Inspect the sandbox environment and home asset.
3. Confirm that the run has `GROK_HOME` and `auth.json`.
**Paperclip version or commit**
`3df33b5b8f49063a5d1ab608f8ce372572ef09d1`
**Deployment mode**
Remote sandbox run.
## What Changed
- Stage a private temporary Grok home for remote subscription runs.
- Copy only the allowed `auth.json` file and set its mode to `0600`.
- Pass the staged directory as the remote `home` asset.
- Set `GROK_HOME` to the path that the remote runtime reports.
- Remove the staged directory before awaited teardown calls.
- Keep the API-key lane free of credential staging.
- Add tests for the allowlist, file mode, empty source home, run lanes,
and teardown cleanup.
## Verification
- `pnpm vitest run packages/adapters/grok-local` passes.
- `pnpm --filter @paperclipai/adapter-grok-local typecheck` passes.
- `grok-home.test.ts` covers the allowlist, mode `0600`, and empty
source home.
- `execute.test.ts` covers the remote subscription lane, the API-key
lane, and cleanup after restore failure.
## Risks
- The change affects only remote Grok subscription runs that use a
credential file.
- The allowlist limits the staged content to `auth.json`.
- The API-key lane does not stage a home or set `GROK_HOME`.
- CI must confirm adapter behavior across the supported runtime matrix.
## Model Used
- Codex, GPT-5, current 2026 model version, large context window,
reasoning mode, and tool use assisted the repository handoff and pull
request management. The implementation author supplied the code and
local verification.

Co-authored-by: Paperclip <noreply@paperclip.ing>
## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The runner subsystem pairs a Rust runner process with a durable
control plane in TypeScript. The control plane is the authority for
every command the runner executes
> - That pair has a crash-recovery contract. If the runner dies between
journaling a command and confirming the command's effect, it must not
run the command twice
> - The runner keeps its side of the contract. On restart it promotes
such a command to the `indeterminate` status and reports that status
back
> - The control plane did not accept `indeterminate`. It closed the
connection without a diagnostic, the runner reconnected and replayed the
same result, and the loop repeated forever
> - This pull request accepts `indeterminate` as a terminal command
status
> - The benefit is that a session survives a runner crash during a tool
call, instead of hanging until a 30 second deadline expires
## Linked Issues or Issue Description
No public issue exists for this defect, so it is described here.
**What happened?**
A live session cannot resume after the runner process is killed during a
governed tool call. The resumed transport waits for the provider
identity for
30 seconds and then fails with `runnerd did not report its provider
identity`.
`packages/paperclip-runner/src/live/live-session.test.ts` covers this
exact
sequence in "terminates real runnerd after a durable receipt and resumes
its
exact provider thread". That test has a 15 second budget, so it reports
the
defect as `Test timed out in 15000ms` and reads like a flake.
**Expected behavior**
The resumed control plane accepts the runner's recovery report, the
runner
reports its provider identity, and the session resumes on its original
provider thread.
**Steps to reproduce**
Build the runner binary, then run the test:
```
cargo build --manifest-path packages/paperclip-runner/runner/Cargo.toml --locked --workspace --bins
cd packages/paperclip-runner
npx vitest run src/live/live-session.test.ts -t "terminates real runnerd"
```
It fails every time on an idle machine. It also fails at `560e7e48b`,
the
commit that added the test, so the defect is not a recent regression.
**Paperclip version or commit**
Reproduced on `master` at `0a422fda5`, which is the base of this branch.
**Deployment mode**
Local development, running the package test suite.
**Root cause**
`DurablePrpControlPlane.#commandResult` accepted only `completed`,
`failed`
and `rejected`. The runner reports a journaled-but-unconfirmed command
as:
```json
{ "status": "indeterminate",
"result": { "code": "execution_indeterminate",
"message": "runner recovered after journaling this command; it will not execute twice" } }
```
That status fell through to a silent `connection.close()`. The runner
reconnected after 250 ms, replayed the same result, and was closed
again. No
durable event ever reached the control plane, so the transport never saw
`harness.ready`.
`indeterminate` is a deliberate part of the runner's contract. See
`reconcile_pending_commands` in
`packages/paperclip-runner/runner/crates/runner-core/src/durable/state.rs`.
The rest of the TypeScript code already models the status; only this
control
plane did not.
## What Changed
- `DurablePrpControlPlane.#commandResult` accepts `indeterminate` as a
terminal command status.
- The persisted-state validation accepts `indeterminate`, so a control
plane
restarted over the same directory can read its own saved state back.
Without this, accepting the status would make the next restart throw.
- `DurableRecoveryCoreCommand.status` includes `indeterminate` in both
declarations of that interface.
- Added an integration test that drives the exact recovery frame the
runner
sends. It asserts the connection stays open, the next command is
delivered,
the status is persisted, a restarted control plane reloads it, and a
replayed duplicate is absorbed rather than treated as a conflict.
## Verification
All commands run from `packages/paperclip-runner`.
- New test fails before the change and passes after it. Before:
`expected null to match object { kind: 'command' }` — `null` is the
closed
connection.
`npx vitest run src/control-plane/durable-prp-control-plane.test.ts`
→ 4 passed.
- The live runner test that exposed this reproduced
**deterministically** on an
idle machine before the change, and now passes in 3.3 s, well inside its
existing 15 s budget. Ran it 10 times in a row: 10/10 pass, 0 failures.
`npx vitest run src/live/live-session.test.ts -t "terminates real
runnerd"`
- Full package suite: `npx vitest run` → 1298 passed, 1 failed. The one
failure is `src/mock-core/local-runner.test.ts > cleans up the harness
process group when the controller closes`. It fails identically on an
unmodified checkout in the same container, so it is a pre-existing
environment issue and not related to this change.
- Typecheck: `tsc -p tsconfig.json --noEmit` → clean.
I did **not** raise the test's timeout. The budget was never the problem
—
with a 600 s budget the same test still failed, at 31 s, with the real
error.
## Risks
Low risk, and it widens rather than narrows what is accepted.
- Behaviour only changes for a status that is currently rejected, so no
previously working path is affected.
- `indeterminate` is terminal, not successful. A caller waiting on such
a
command still receives an error from the transport, which is correct:
the
effect is genuinely unconfirmed. This change does not make an
unconfirmed
command look like it succeeded.
- The persisted-state change only widens an allow-list, so existing
state
files stay valid.
Open topics for a reviewer:
- The control plane closes connections without any diagnostic. That
silence is
why this defect looked like a flaky test. Adding a diagnostic channel is
a
larger change and is not included here.
- `DurableRecoveryProcessedCommand` in
`src/contracts/durable-recovery.ts`
drifts from the Rust `StoredCommandResult` by more than this status: it
declares `commandDigest` and `logicalEffectCount`, which Rust does not
have,
and omits `commandType`, which Rust does. That is a separate correction
and
is deliberately not folded in here.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The runner subsystem drives a Codex provider process and reads its
events with `CodexProvider::poll`
> - The Codex provider integration tests wait for those events in poll
loops
> - Two of those loops count iterations instead of measuring time, so
they stop waiting too early
> - This makes `cargo test` fail at random on branches that change no
Rust code
> - This pull request bounds the two loops by wall clock, like every
other wait in the same file
> - The benefit is that a red CI job now means a real defect
## Linked Issues or Issue Description
**What happened?**
`packages/paperclip-runner/runner/crates/runner-core/tests/codex_provider.rs`
fails
`cargo test` at random. The failure appears in the `ci / Build` job with
exit code 101.
It appears on branches that change no Rust code. Two tests fail:
-
`ambiguous_or_dead_replacement_start_preserves_result_not_exit_authority`
at line 1274
- `ambiguous_replacement_turn_adopts_one_later_completion_identity` at
line 1443
Both assertions report `left: None`. The value is not wrong. The loop
never saw the
`CodexProviderEvent::Exited` event at all.
**Expected behavior**
The tests must wait for the provider process to exit. A test must fail
only when the
provider gives a wrong result.
**Steps to reproduce**
1. Build the integration test: `cargo test --test codex_provider
--no-run`.
2. Run one of the two named tests 25 times in a row.
3. About 8 of the 25 runs fail with `left: None`.
**Paperclip version or commit**
Reproduced on `master` at `2e5a24e17`.
**Related pull requests**
Refs #12241. That pull request also edits
`packages/paperclip-runner/runner/crates/runner-core/tests/codex_provider.rs`.
It does not
fix these two loops. The two changes may need a merge if both land.
**Root cause**
`CodexProvider::poll` (`crates/runner-core/src/codex_provider.rs:824`)
reads with a 1 ms
timeout. That timeout does not apply on every path.
`ProcessSupervisor::receive_stdout_line`
(`crates/runner-core/src/process_supervisor.rs:293`)
returns at once, and uses none of the 1 ms budget, in two cases:
`StdoutClosed` at line 309
and `RecvTimeoutError::Disconnected` at line 315.
A child process closes its pipes before its exit status is ready to
reap. In that window
every `poll()` call returns `Ok(None)` in nanoseconds. A loop of 64 or
128 iterations then
ends in microseconds, before the exit status is available. The failing
run above ends in
0.06 s.
## What Changed
- `tests/codex_provider.rs`: bound the exit wait at line 1256 by a 5
second deadline instead
of 64 iterations.
- `tests/codex_provider.rs`: bound the exit wait at line 1397 by a 5
second deadline instead
of 128 iterations.
- Both loops now sleep 1 ms when `poll()` returns no event. This copies
the pattern that the
same file already uses at line 1511 and in every `wait_for_*` helper.
- No production code changes. The change is test-only.
## Verification
Measured before and after the change. Each test ran 25 times in
sequence, on an idle
machine, with `--test-threads=1`.
| test | before | after |
|---|---|---|
|
`ambiguous_or_dead_replacement_start_preserves_result_not_exit_authority`
| 8 / 25 failed | 0 / 25 failed |
| `ambiguous_replacement_turn_adopts_one_later_completion_identity` | 9
/ 25 failed | 0 / 25 failed |
The full `codex_provider` suite also ran 12 times with
`--test-threads=4` after the change.
Every run passed.
Commands:
```
cargo test --test codex_provider --no-run
cargo test --test codex_provider
```
## Risks
Low risk. The change touches test code only. It makes two waits longer
in the failure case:
a genuinely broken provider now takes up to 5 seconds to fail these two
tests instead of
microseconds. Every other wait in this file already uses the same 5
second deadline.

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

> - The adapter and its required sandbox ingress had separate settings.
> - A user could enable one setting and still have an unusable runner
configuration.

authorization.

native runs.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
This improves the experimental settings and transport authorization for
Paperclip Runner.
**Subsystem affected**
Cross-cutting. This change affects the React settings UI, shared
settings contracts, adapter utilities, and server runtime selection.
**Current behavior**
Settings shows separate Paperclip Runner and Runner Preview Ingress
controls. A user can enable the runner but leave required sandbox
ingress disabled.
**Proposed behavior**
Settings shows only Paperclip Runner. Its native runtime decision also
authorizes provider WebSocket ingress when the execution target requires
it. A persisted native run keeps its recovery transport after the
setting is disabled.
**Reason and benefit**
Paperclip Runner is one experimental capability. One opt-in removes an
invalid partial configuration and makes the rollout boundary easier to
understand.
**Breaking changes**
The Runner Preview Ingress card is removed. The old
`enableRunnerPreviewIngress` key remains accepted in stored settings and
managed configuration, but it has no server runtime effect. The public
adapter-utils input remains compatible through a deprecated alias.
**Additional context**
Refs: #12638, #12641, #12656.
## What Changed
- Removed the separate Runner Preview Ingress card from Experimental
Settings.
- Made resolved native runtime selection authorize required provider
ingress.
- Preserved ingress recovery for persisted native runs after the rollout
flag is disabled.
- Kept the old settings key and adapter-utils input as deprecated
compatibility contracts.
- Added focused UI, runtime policy, transport, stored-settings, and
managed-config regression tests.
- Updated deployment documentation and feature descriptions.
## Verification
- GitHub Actions will run typecheck, tests, build, policy, and browser
shards.
- Focused tests cover the single settings control, runtime
authorization, fail-closed transport selection, the deprecated public
input, and old managed configuration.
- No local tests were run, per the maintainer request to use GitHub
Actions for verification.
- `git diff --check` passes.
## Risks
Low to moderate risk. The effective ingress gate changes from a separate
stored flag to the resolved native run decision. Fresh runs still
require `enableNativeRunner`. Persisted native runs remain recoverable.
Legacy adapters never receive ingress authorization.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip Runner needs repeatable evaluation contracts.
> - Evaluation code must stay separate from provider launch and
production orchestration.
> - Offline fixtures need stable compatibility, scoring, traceability,
and report rules.
> - Published Runner consumers need only the supported evaluation
contract surface.
> - This pull request adds offline evaluation tooling and a
workspace-private matrix kernel.
> - The benefit is deterministic evaluation without credentials or paid
provider calls.
## Linked Issues or Issue Description
Refs #11297
This pull request extracts the offline evaluation unit from the earlier
aggregate Runner work.
## What Changed
- Add a workspace-private, provider-neutral evaluation matrix kernel.
- Add the public `@paperclipai/paperclip-runner/evals` compatibility and
native execution contracts.
- Add fail-closed runnerd artifact and protocol compatibility checks.
- Add deterministic workflow catalogs, scoring, traceability, and report
generation.
- Add sanitized Codex, OpenCode, and ACPX fixtures.
- Add package-boundary and clean-consumer checks.
- Add the eval package manifest to the Docker dependency stage.
- Add the generated protocol fixture digest without changing the
lockfile.
## Verification
GitHub Actions must run:
- Runner TypeScript and Rust type checks.
- Runner unit and protocol tests.
- Evaluation kernel tests.
- Workflow traceability checks.
- Clean-consumer and package-boundary checks.
- Repository test, type-check, build, policy, and security gates.
No local test command was run. The repository owner requested
GitHub-only verification.
## Risks
This is a large greenfield review surface with 51 files. The code does
not launch a live provider or load credentials. Package and protocol
drift fail closed. The workspace lockfile remains under the existing
CI-owned process.
## Model Used
OpenAI Codex with the GPT-5 agent model. The work used high reasoning,
repository inspection, tool use, and parallel code review.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip Runner currently enables only the Codex production path.
> - The package also contains dormant OpenCode and ACPX provider
boundaries.
> - Dormant boundaries must still fail safe before later activation
work.
> - Provider children must not inherit unrelated server secrets or host
homes.
> - Permission defaults must require interaction instead of broad
automatic approval.
> - This pull request hardens those boundaries without activating them.
> - The benefit is a safer base for later provider-specific runnerd
work.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
This improves the inactive OpenCode and ACPX provider boundary in
Paperclip Runner.
**Subsystem affected**
The adapter permission contract, Runner provider environment, and native
execution input builder.
**Current behavior**
Dormant OpenCode code can inherit the full server environment. Its
default permission mode allows operations. ACPX also defaults to broad
approval. The provider guard can accept inherited object property names.
**Proposed behavior**
Use exact provider identifiers. Use interactive defaults. Allow only
required OpenCode environment keys. Reject invalid proxy permission
modes.
**Reason and benefit**
This reduces accidental authority and secret exposure before future
provider activation.
**Breaking changes**
No production provider is activated. Codex runtime selection and Codex
credential-home discovery do not change. Dormant OpenCode and ACPX
callers that omit permission modes now receive safer defaults.
## What Changed
- Change dormant OpenCode and ACPX permission defaults to interactive
modes.
- Reject prototype property names as provider identifiers.
- Default dormant ACPX input to the qualified Codex agent profile.
- Add an explicit OpenCode runner environment allowlist.
- Exclude host homes, server credentials, database values, and Node
injection options.
- Add a fail-closed OpenCode proxy permission parser.
- Add focused tests for defaults, filtering, and invalid values.
## Verification
GitHub Actions must run:
- Adapter utility tests.
- Paperclip Runner tests, type checks, and build.
- Server native runtime tests.
- Repository test, type-check, build, policy, and security gates.
No local test command was run. The repository owner requested
GitHub-only verification.
## Risks
Future OpenCode credential providers must add required variables to the
allowlist through review. The safer defaults can pause dormant internal
scenarios that relied on implicit broad approval. Production Codex
behavior is unchanged.
## Model Used
OpenAI Codex with the GPT-5 agent model. The work used high reasoning,
repository inspection, tool use, and parallel security review.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip supports direct adapters and an experimental native Runner
path.
> - These paths need one stable compatibility matrix.
> - The matrix must not launch providers or load credentials during
normal tests.

> - The benefit is a reviewable contract for later end-to-end executors.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
This improves verification for direct adapters and Paperclip Runner
providers.
**Subsystem affected**
Cross-cutting test infrastructure for adapters, the server runtime, and
the task thread.
**Current behavior**
The repository has subsystem tests. It does not have one declarative
matrix for direct and native compatibility.
**Proposed behavior**
Add a pure acceptance catalog, result validator, redaction helpers, and
failure classification. Keep all execution authority outside this
change.
**Reason and benefit**
The matrix makes legacy isolation and native recovery requirements
explicit. The helpers let later executors report safe and complete
results.
**Breaking changes**
None. This change does not alter production runtime selection or start
any provider.
## What Changed
- Add a catalog for built-in direct adapters and qualified native
provider profiles.
- Add compatibility cases for runtime selection, task threads,
questions, and flag-change recovery.
- Add pure redaction and transient-failure classification helpers.
- Add fail-closed Markdown and JUnit report aggregation.
- Add isolated test and type-check commands.
- Document the credential-free boundary and deferred live execution
work.
## Verification
GitHub Actions must run:
- `pnpm test:runner-acceptance`
- `pnpm test:runner-acceptance:typecheck`
- The repository test, type-check, build, policy, and security gates.
No local test command was run. The repository owner requested
GitHub-only verification.
## Risks
Low production risk. The change adds test-only files and root scripts.
The catalog can drift when a built-in adapter changes. Its validation
fails closed on that drift.
## Model Used
OpenAI Codex with the GPT-5 agent model. The work used high reasoning,
repository inspection, tool use, and parallel code review.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Administrators need bounded controls for experimental native
execution.
> - The lower stack adds remote Codex execution and the task workspace.

## Linked Issues or Issue Description
Refs #12640.
Refs #12616.
Refs #12352.
**Subsystem affected**
Agent configuration, instance experimental settings, run ledger,
provider trace inspector, and administrator actions.
**Problem or motivation**
The native runner lacks one safe operator surface for Codex permissions,
lifecycle, raw trace capture, and run inspection. The integration branch
also contains provider choices that the production backend cannot
execute yet.
**Proposed solution**
Expose only the qualified Codex controls. Keep Paperclip Developer Mode
and runner preview ingress off by default. Gate raw trace actions by
administrator access and existing trace authorization.
**Alternatives considered**
Exposing unfinished providers would create configurations that fail at
runtime. Always-on tracing would increase sensitive data and storage
risk.
**Roadmap alignment**
This work supports governed Cloud and Sandbox agents and production
diagnostics.
## Stack
- Base PR: #12640.
- Lower PRs: #12639 and #12638.
- This PR contains only its 54-file administration and observability
delta.
- This is the final feature PR in the Codex production stack.
## What Changed
- Added Codex-only Paperclip Runner permission and lifecycle controls.
- Added bounded warm idle configuration.
- Kept the provider field fixed to Codex.
- Added administrator-only one-run raw trace requests.
- Added a persistent future-run raw trace toggle.
- Added trace status, metadata, ledger, and canonical runner inspection.
- Added JSON-RPC request-origin grouping and finalization lineage.
- Restored the stateful PRP transcript parser and focused projection
tests required by trace inspection.
- Added default-off Paperclip Developer Mode.
- Added Honeycomb run links for authorized developer mode.
- Disabled the legacy operational skill for `paperclip_runner`.
- Did not expose OpenCode, ACPX, Pi, Claude Managed, or AWS runner
choices.
- Did not change migrations, workflows, dependencies, or
`pnpm-lock.yaml`.
## Verification
- GitHub Actions will run UI tests, server tests, repository typecheck,
build, browser tests, security, and policy gates.
- Tests cover Codex configuration defaults and bounds, administrator
trace actions, persistent settings, ledger inspection, trace lineage,
and Honeycomb links.
- Existing server trace authorization and retention tests remain the
backend authority.
- Local tests were not run. The requested verification policy uses
GitHub Actions for this series.
- `git diff --check runner/task-workspace-experience...HEAD` passes.
- The delta contains 54 files.
## Risks
- Raw provider traces can contain sensitive provider data.
- Existing server authorization controls access, reveal, download,
retention, and deletion.
- The UI gates trace actions by administrator access and developer mode.
- All new instance settings remain off by default.
- Fresh Paperclip Runner configuration remains Codex-only.
- Direct adapters and legacy task behavior do not change in this PR.

path.
> - The lower stack PR adds authenticated remote execution targets and

## Linked Issues or Issue Description
Refs #12638.
Refs #12616.
Refs #12352.
**Subsystem affected**
Paperclip Runner Rust transport and remote runner networking.
**Problem or motivation**
The runner daemon cannot connect to a public control plane with TLS. It
also cannot accept a provider preview connection on the run-bound
ingress path.
**Proposed solution**
Add WSS with native trust roots and an optional private CA bundle. Add a
fixed authenticated listener mode for provider ingress. Advertise the
exact transport contract through build metadata.
**Alternatives considered**
Plaintext public WebSocket connections would weaken the transport
boundary. A general listener would expose more network surface than the
run-bound provider ingress requires.
**Roadmap alignment**
This work supports the Cloud and Sandbox agents milestone. It also
supports self-healing native runs.
## Stack
- Lower merged PR: #12638.
- This PR contains only its 13-file delta against `master`.
- Later stack PRs add the task workspace and administrator UI.
## What Changed
- Added WSS dialing with rustls and native certificate roots.
- Added an optional bounded private CA bundle that augments native
roots.
- Kept plaintext WebSocket dialing restricted to loopback addresses.
- Pinned resolved dial addresses for the process lifetime.
- Added a fixed `0.0.0.0:43127` listener with an exact run-bound path.
- Rejected listener queries, ambiguous paths, and WebSocket extensions.
- Kept frame and message size bounds.
- Added bounded reconnect grace and exponential jitter.
- Retried bootstrap failures only before authentication proof
transmission begins.
- Kept post-proof failures fail-closed and bounded the welcome exchange
at two seconds.
- Added runnerd build metadata for the versioned transport contract.
- Updated Rust dependencies and `Cargo.lock` only for TLS and
certificate handling.
- Did not add provider dispatch, Pi, AWS, `pnpm-lock.yaml`, migrations,
or workflows.
## Verification
- GitHub Actions will run Cargo formatting, Rust tests, repository
tests, typecheck, build, security, and policy gates.
- Rust tests cover URL validation, listener path validation, build
metadata, durable recovery, and the existing Codex provider path.
- Local tests were not run. The requested verification policy uses
GitHub Actions for this series.
- `git diff --check master...HEAD` passes.
- The delta contains 13 files.
## Risks
- TLS and listener changes affect the runner trust boundary.
- Public plaintext transport remains rejected.
- The listener uses one fixed port and one exact run-bound path.
- PRP authentication remains required after the WebSocket upgrade.
- The optional CA file uses the existing private-file checks and a 4 MiB
limit.
- This PR does not enable another provider or change direct adapters.

## Linked Issues or Issue Description
Refs #12616.
Refs #12352.
**Subsystem affected**
Cross-cutting. This change touches runner transport, server
orchestration, plugin contracts, and shared settings.
**Problem or motivation**
Native execution cannot resolve an authenticated runner ingress through
a remote environment. The server also lacks one provider-neutral
contract for remote execution targets.
**Proposed solution**
Add a default-off runner preview ingress capability. Add
transport-neutral runner connectivity. Add remote execution target and
lifecycle handling. Add a Daytona ingress implementation with redacted
credentials.
**Alternatives considered**
A provider-specific server path would duplicate orchestration and
authorization. A public endpoint without an environment contract would
weaken the trust boundary.
**Roadmap alignment**
This work supports the Cloud and Sandbox agents milestone. It also
supports self-healing runs and governed tool access.
## What Changed
- Added execution-target traits for local, SSH, and sandbox
environments.
- Added plugin RPC contracts for runner ingress endpoints.
- Added authenticated Daytona preview ingress.
- Added transport-neutral PRP outbound connections.
- Added remote runner artifact verification and fail-closed provider
selection.
- Added bounded native session resume, cancellation, and lifecycle
recovery.
- Preserved Codex-only selection for fresh experimental runner starts.
- Preserved all direct adapter execution and finalization paths.
- Removed stale Pi provider-pack requirements that security review
rejected.
- Kept the rollout controls off by default.
- Did not change pnpm-lock.yaml, Cargo, database migrations, or GitHub
workflows.
## Verification
- GitHub Actions will run the repository test, typecheck, build,
security, and policy gates.
- Focused tests cover ingress validation, redaction, execution targets,
remote lifecycle, cancellation, resume, and legacy adapter selection.
- Local tests were not run. The requested verification policy uses
GitHub Actions for this series.
- `git diff --check origin/master...HEAD` passes.
- The diff contains 52 files.
## Risks
- Remote execution crosses a trust boundary.
- The implementation validates target capabilities, artifact digests,
provider-pack pins, and connection metadata.
- The feature remains default-off.
- Fresh native selection remains Codex-only.
- Existing direct adapters remain on the legacy path.
- This PR does not yet make remote Codex runnable. The next PR adds the
Rust WSS and TLS transport.
## Model Used
OpenAI Codex with GPT-5.6. The work used high-reasoning agent mode,
repository tools, GitHub tools, and parallel code-audit agents.

## Thinking Path
> - Paperclip is the open source control plane for teams of AI agents.
> - Agent runs currently use direct adapters and their established
finalization paths.
> - The new runner package needs one production integration before it
can execute a real provider through the server.
> - That integration must not change direct adapters or expose
unsupported providers.
> - The rollout must also preserve native runs that were already
recorded when the feature flag changes.
> - This pull request adds a default-off, Codex-only native execution
path and its authority boundary.
> - The benefit is a recoverable production vertical slice with explicit
compatibility guards.
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting server orchestration and adapter selection.
**Problem or motivation**
The runner package exists, but the server cannot yet start and recover a
governed Codex run through it. A careless integration could also route
existing direct adapters into the native runtime or lose cancellation
and finalization state.
**Proposed solution**
Add a hidden `paperclip_runner` adapter for Codex. Keep it behind the
default-off instance flag. Bind native execution, resume, cancellation,
semantic tool authority, and finalization to the recorded company,
issue, run, and coordinator identities. Leave every direct adapter on
its existing path.
**Alternatives considered**
A multi-provider launch was rejected because only Codex has the complete
production bridge in this series. Replacing direct adapter execution was
rejected because the runner remains experimental.
**Roadmap alignment**
This work supports governed tool access, action attribution, and
self-healing runs. It keeps the integration narrow and default-off.
## What Changed
- Add the Codex-only native session executor and persisted resumption
path.
- Add run-scoped semantic tool projection, authorization, receipts, and
idempotency.
- Add audited native cancellation with durable issue and coordinator
binding.
- Add result fencing so a recorded result cannot reacquire the provider
and run twice.
- Reject fresh runner starts when the rollout flag is off while
preserving recorded native recovery.
- Keep direct adapters outside native status, cancellation, record
creation, and finalization.
- Add focused conformance, recovery, cancellation, status, portability,
and compatibility coverage.
## Verification
- GitHub Actions is the authoritative test environment for this large
stack.
- The PR policy and lightweight stack checks run while this is a middle
PR.
- The full required suite runs when this PR becomes the lowest unmerged

## Risks
- The main risk is routing a legacy adapter into native execution.
Runtime selection and heartbeat tests cover that boundary.
- The next risk is stale or cross-company cancellation. Durable binding
checks and transactional audit persistence cover it.
- The adapter remains hidden and default-off. Only Codex is admitted.
- There are no database migration, lockfile, or GitHub workflow changes
in this PR.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The runner package already provides the production protocol and
execution spine.
> - Contributors still need stable SDK surfaces, deterministic test
tools, and local inspection tools.
> - Those surfaces share generated contracts and must change as one
package boundary.
> - This pull request adds the package-local SDK, labs, examples, and
drift checks.
> - The benefit is a reviewable developer platform that does not change
application execution selection.
## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` — runner SDK, conformance tools, and
developer tooling.
**Problem or motivation**
The production runner spine is present, but package consumers cannot
build deterministic integrations, inspect sessions, or verify
provider-neutral behavior through supported surfaces.
**Proposed solution**
Add browser, React, standalone, live-session, scenario, conformance, and
evaluation surfaces. Add generated contract inventories and
package-local verification scripts. Keep production application routing
unchanged.
**Alternatives considered**
We considered splitting each generated catalog, SDK surface, and demo
into separate pull requests. Those changes share exports, fixtures, and
drift gates. Splitting them would create intermediate package states
that do not build.
**Roadmap alignment**
No overlapping item appears in `ROADMAP.md`. This work extends the
runner package that is already on `master`.
## What Changed
- Add browser, React, standalone, live-session, and issue-thread SDK
surfaces.
- Add deterministic mock control-plane, scenario, conformance, replay,
and evaluation tools.
- Add bounded Codex, OpenCode, and ACPX development transports and
fixtures.
- Keep deferred managed-provider execution fail-closed. Persisted
compatibility data remains readable.
- Add generated capability inventories with their source files and drift
checks.
- Add examples, package documentation, browser checks, and
clean-consumer checks.
- Preserve the reviewed protocol bounds, replay compatibility aliases,
process environment isolation, and semantic redaction limits.
- Update the ACPX package patch that the existing workspace patch
registry already tracks.
- Do not change `pnpm-lock.yaml`, repository workflows, server runtime
selection, or the application UI.
## Verification
GitHub Actions is the verification authority for this pull request. The
repository CI, package TypeScript and Rust checks, package tests,
generated-output drift checks, browser checks, security scans, and
Greptile review must pass on the exact head.
Local test suites were not run because this series uses parallel GitHub
Actions for verification.
## Risks
This is a large greenfield package change. The main risks are public
export drift, generated-output drift, and optional React consumer
compatibility. Package boundary checks, clean-consumer checks, and
browser tests cover those risks. Production adapter selection and server
execution are outside this pull request.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Apps system gives agents governed access to external services
> - The managed Google Workspace connector uses separate profiles for
each app and access level
> - Several app definitions and callback paths did not enforce the same
profile contract

managed read profile was available
> - This pull request aligns the profile contracts, setup guidance,
default selection, and activity attribution

## Linked Issues or Issue Description
N/A — no public GitHub issue exists for this follow-up. Related merged
work:
[#12600](https://github.com/paperclipai/paperclip/pull/12600) and
[#12609](https://github.com/paperclipai/paperclip/pull/12609).
This change follows the merged Paperclip Cloud managed OAuth broker
work. It does not add a new broker or provider client.
**What happened?**
The Google Workspace connection definitions could drift from the shared
connector profile registry. The callback activity always named Gmail.
Google Sheets did not show the Developer Preview requirement. The setup
flow could select a customer-owned write method when Cloud advertised
only a managed read profile. The tool-access service had no non-Gmail
managed callback test.
**Expected behavior**
Each managed Google Workspace profile must use its exact app slug, MCP
URL, scopes, ownership, risk tier, and write-tool policy. Callback
activity must name the correct app and profile. Every Google Workspace
card must show the same Developer Preview prerequisite. An available
managed method must be the default within the selected capability. The
customer-owned method must remain available as a fallback.
**Steps to reproduce**
1. Advertise only the `gmail.read` managed profile.
2. Open the Gmail connection setup.
3. Observe that the customer-owned draft method becomes the default.
4. Complete a managed Google Drive callback.
5. Observe that the activity row names Gmail instead of Google Drive.
6. Open the Google Sheets setup.
7. Observe that it does not show the Google Developer Preview
prerequisite.
**Paperclip version or commit**
Current `master` at the start of this follow-up.
**Deployment mode**
Local development. The same connector definitions apply to Cloud-hosted
and self-hosted instances.
**Installation method**
Built from source with pnpm.
**Agent adapter(s) involved**
Not adapter-specific. This change affects the core Apps and tool-access
paths.
## What Changed
- Added one table-driven invariant for all 16 Google Workspace profiles.
- Verified each profile against its app slug, MCP URL, exact scopes,
capability, ownership, grant kind, risk tier, and write-tool allowlist.
- Kept the Google Chat write profile least-privilege because its only
enabled write tool is `send_message`.
- Added the Google Developer Preview prerequisite to Google Sheets.
- Preferred an available Paperclip-managed method before a
customer-owned method.
- Preserved explicit capability selection and the customer OAuth
fallback.
- Switched managed-profile availability from the anonymous global
capability document to the enrolled instance's signed status response,
so internal-pilot profiles cannot be enabled locally without an
authorized instance binding.
- Replaced the Gmail callback activity constant with the validated app
slug and connector profile.
- Added connector and route coverage for signed per-instance
capabilities, including inactive and malformed responses.
- Added a Google Drive callback test that covers the signed profile
request, personal vault refs, encrypted secret rows, catalog filtering,
and non-sensitive activity details.
## Verification
- `pnpm -r typecheck` — passed across all workspaces before the
signed-capability follow-up; final targeted shared and server typechecks
also passed after it.
- `pnpm exec vitest run
server/src/services/paperclip-cloud-connector.test.ts` — passed, 9
tests.
- `pnpm exec vitest run packages/shared/src/app-definitions.test.ts` —
passed, 19 tests.
- `pnpm exec vitest run
server/src/__tests__/tool-access-service.test.ts` — passed, 205 tests.
- `pnpm test:run` — incomplete after the general server group reported
five failures in `server/src/__tests__/workspace-runtime.test.ts`. The
failures are outside the changed files. The run was stopped before the
remaining serialized suites because the shared worktree was needed for a
follow-up edit.
- `pnpm build` — passed on the final tree.
- `git diff --check` — passed on the final tree.
The five full-suite failures were:
- `records teardown and cleanup operations when a recorder is provided`
- `does not accept an occupied allocated port when listener ownership is
unavailable`
- `backfills a pre-existing HTTP-only managed worktree runtime to
verified HTTPS in place`
- `re-adopts a live service whose shell command differs from the
surviving process argv`
- `reuses a registered legacy worktree that already has the branch
checked out`
## Risks
- The default setup method changes when at least one Paperclip-managed
method is available. Explicit read, write, or draft choices still stay
within the selected capability group.
- Managed method availability now depends on Paperclip Cloud's signed
enrolled-instance status. A Cloud outage or an inactive enrollment hides
managed methods while leaving customer-owned OAuth available.
- The callback activity schema gains a non-sensitive `profile` value. It
does not include tokens, account identifiers, emails, tenant
identifiers, or provider error text.
- The profile invariant is strict. A future Google scope or tool change
must update the shared registry and the matching app definition
together.
- There are no database migrations and no public API changes.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The heartbeat runtime classifies adapter run failures, and the
recovery service uses that classification to decide between automatic
retry, a timed provider-quota wait, and a board escalation
> - The Claude CLI changed its subscription-limit stop message to
"You've hit your limit · resets 2:30am (UTC)", and no quota matcher
knows this qualifier-less wording
> - A limit-hit run therefore classifies as `adapter_failed` (or
`claude_auth_required`), recovery burns its continuation retries against
a hard limit, and the issue blocks with the opaque "No live execution
path" notice instead of waiting for the reset and retrying automatically
> - This pull request teaches the adapter and the recovery service the
new wording, and titles stranded-escalation notices from the classified
run error code so operators see the cause at a glance
> - The benefit is that usage-limit stops self-heal at the provider
reset time, and the notices that do post say "Error: usage limit
reached" or "Error: not logged in to Claude" instead of a generic title
## Linked Issues or Issue Description
No public issue exists; the underlying problem follows the bug template:
**What happened?**
On a staging deployment, an assigned `in_progress` issue hit the Claude
subscription usage limit. The run recorded the error `Claude run failed:
subtype=success: You've hit your limit · resets 2:30am (UTC)`. The
automatic continuation retry failed the same way in 34 seconds with
`errorCode: adapter_failed`. Terminal-run recovery then escalated: the
issue moved to `blocked` with the notice "No live execution path" and a
board-owned recovery action. The notice gave the operator no indication
that the cause was a usage limit with a known reset time.
**Expected behavior**
A usage-limit stop classifies as `provider_quota` with the reset clock
parsed into `retryNotBefore`. The recovery service takes its
provider-quota wait path: a system-owned recovery action that waits for
the reset time and retries the original assignee automatically. If an
escalation notice does post, its title names the classified cause.
**Steps to reproduce**
1. Run a `claude_local` agent on an issue until the Claude subscription
limit is hit, so the CLI result is "You've hit your limit · resets
\<time\> (UTC)".
2. Let terminal-run recovery retry the continuation.
3. Observe the issue block with the "No live execution path" notice
instead of a timed quota wait. `classifyAdapterFailureForRecovery`
returns `null` for the recorded error text; `CLAUDE_PROVIDER_QUOTA_RE`
and `PROVIDER_QUOTA_ERROR_RE` both fail to match it.
## What Changed
- `CLAUDE_PROVIDER_QUOTA_RE` and `CLAUDE_EXTRA_USAGE_RESET_RE`
(claude-local adapter) accept "you've hit your limit" with no qualifier,
alongside the existing "session"/"usage" wordings, so the run classifies
as `provider_quota` and the reset clock lands in `retryNotBefore`.
- `PROVIDER_QUOTA_ERROR_RE` and `isProviderQuotaRecovery` (recovery
service) accept the same wording, so runs recorded before the adapter
fix (errorCode `adapter_failed` with the limit text in the error) also
route to the quota wait.
- `parseProviderQuotaClockReset` parses the "resets 2:30am (UTC)" clock
shape alongside the existing "try again at" shape.
- `buildStrandedRecoveryEscalationNotice` titles the notice from the
source run's classified error code when one is mapped: `provider_quota`
→ "Error: usage limit reached", `claude_auth_required` → "Error: not
logged in to Claude", `acpx_auth_required` → "Error: agent login
required". The raw failure text stays withheld from the issue thread;
only the server-classified code is surfaced. Unmapped codes keep the
existing seed/cause titles.
## Verification
- `pnpm vitest run
packages/adapters/claude-local/src/server/parse.test.ts
server/src/services/recovery/provider-failure-classification.test.ts
server/src/services/recovery/stranded-notice.test.ts` — 72 tests pass,
including 5 new cases that use the exact new CLI message.
- `pnpm vitest run server/src/__tests__/issue-recovery-actions.test.ts
server/src/__tests__/heartbeat-retry-scheduling.test.ts
server/src/__tests__/heartbeat-process-recovery.test.ts` — 189 tests
pass (no reroute regressions from the widened matchers).
- `tsc --noEmit` clean for `@paperclipai/adapter-claude-local` and
`@paperclipai/server`.
## Risks
- Low risk. The regex widenings are additive; every previously matched
wording still matches, and the existing negative test ("Workspace
storage capacity limit reached." stays unclassified) still passes.
- Behavioral shift, intended: an `adapter_failed` run whose error text
is the new limit wording now routes to the silent system-owned quota
wait instead of a board escalation. This matches how the older limit
wordings already behave.
- The notice title change only affects escalations whose source run
carries one of the three mapped error codes; all other notices render
exactly as before.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The runner package is useful only when the application can start,
observe, and recover a native Codex run safely.
> - Existing direct adapters must keep their current execution and
finalization paths.
> - The application boundary therefore needs additive persistence,
authorization, coordination, and recovery behind an explicit
experimental adapter.
> - This pull request adds that Codex-only boundary without activating
generalized providers, remote environments, or the later task/SDK
surfaces.
## Linked Issues or Issue Description
**Subsystem affected**
Shared contracts, database persistence, adapter utilities, server
native-runtime services, and the experimental Paperclip Runner adapter.
**Problem or motivation**
The already-landed runner package has a qualified Codex path, but the
application needs durable native-run state, guarded runtime selection,
authenticated coordination, tool security, finalization, and recovery
before the experimental adapter can be exercised safely.
**Proposed solution**
Add a Codex-only `paperclip_runner` application path behind the existing
default-off native-runner setting. Bind native state and coordination to
company/run identity, preserve persisted-run recovery, and leave every
direct adapter on its existing legacy execution path.
**Alternatives considered**
The earlier stack boundary introduced a generalized executor and
remote-environment lifecycle here. That made this PR depend on
implementations in higher PRs and changed reusable sandbox behavior
globally. Those pieces are now deferred together to #12592.
**Roadmap alignment**
ROADMAP.md does not list a conflicting native-runner integration
project. This change adds the application boundary for the existing
Runner architecture.
## What Changed
- Added native run/result/finalization/provider-trace persistence,
shared validators, and idempotent migration/replay coverage.
- Added guarded Codex-only runtime selection, authenticated PRP
coordination, recovery, finalization, and interaction services.
- Added run/company-bound tool-gateway authorization, credential
redaction, SSRF protections, and replay-safe behavior.
- Added the explicit `paperclip_runner` adapter behind the default-off
rollout setting.
- Preserved legacy answered-question wake projection and direct-adapter
execution/finalization paths.
- Hardened cancellation so only owned in-memory child processes are
signaled; persisted recycled PIDs/process groups are never trusted.
- Retained the narrow Claude ACPX isolated-context security follow-up
discovered after #12590.
- Deferred the generalized executor, provider ingress, remote lifecycle,
SDK/lab/eval work, release-process changes, and lockfile.
## Verification
- Changed-file delta against `master`: 133 files.
- GitHub Actions is the authoritative verification environment for this
PR.
- Full CI, security, and Greptile review will run on this lowest
unmerged stack PR.
- Local tests/build/typecheck were not run because this checkout is
resource constrained.
- Static diff/reference checks pass, and `pnpm-lock.yaml` is unchanged.
## Risks
- This touches central heartbeat and agent-route code, so legacy
compatibility is the primary risk.
- Runtime selection remains Codex-only and explicit; direct Codex,
Claude, OpenCode, process, HTTP, and plugin adapters remain on their
existing paths.
- Fresh native starts fail closed while the rollout flag is off;
persisted native records remain readable and recoverable.
- Cancellation, company/run binding, tool calls, status decisions, and
completion writes are guarded or replay-safe.

## Thinking Path
> - Paperclip lets operators give governed tools to AI agents.
> - Connected Apps already support provider OAuth and personal
connection grants.
> - Some providers require one stable callback and do not support
dynamic client registration.
> - Self-hosted Paperclip instances can run at private or changeable
origins.
> - Paperclip Cloud can provide the stable callback while each instance
keeps its durable provider credentials.
> - This pull request adds the instance side of that managed OAuth
protocol and keeps customer-created clients available.
> - The benefit is a safe path to one-click Workspace connections for
hosted and enrolled self-hosted instances.
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting. This change updates the server, Apps UI, shared app
definitions, and connection documentation.
**Problem or motivation**
Some OAuth providers require a pre-registered callback and
provider-owned client. An arbitrary self-hosted Paperclip origin cannot
use that client callback directly. Paperclip ID must also stay limited
to product identity instead of resource authorization.
**Proposed solution**
Use the existing Paperclip Cloud application as the fixed callback
broker. Enroll each instance to an exact origin and separate Ed25519 and
X25519 keys. Bind every request and sealed envelope to the instance,
environment, user, company, provider, profile, and exact scope set.
Store durable provider credentials only in the originating instance
vault.
**Alternatives considered**
Customer-created OAuth clients remain available as the independent
fallback. A generic redirect relay was rejected because it would allow
caller-selected destinations and scopes. Paperclip ID was rejected as
the broker because it is the identity boundary. A new service was
rejected because the existing Cloud application already owns customer
login and the public callback origin.
**Roadmap alignment**
This work extends the shipped MCP Tool Gateway and Apps milestone. It
also supports the Connected Apps and Cloud deployments roadmap items.
Companion Cloud implementation:
https://github.com/paperclipai/paperclip-cloud/pull/312
The duplicate search found no related open Paperclip PR or issue.
## What Changed
- Add a `paperclip_cloud_connector` client with signed requests, exact
profile and scope bindings, and X25519-sealed credential handling.
- Add explicit self-hosted enrollment with owner-only instance key
storage and exact HTTPS origins.
- Route managed Google Workspace setup through Paperclip Cloud and
preserve customer-created OAuth clients.
- Keep broker claims retryable until the local vault transaction
commits.
- Keep managed Google per-profile removal local-only to avoid
client-wide provider revocation.
- Add setup status to the Connections page and retain the Paperclip ID
names as compatibility aliases.
- Document the trust boundaries, enrollment, callback, refresh, removal,
and rollout flows.
## Verification
- `pnpm -r typecheck`
- `pnpm --filter @paperclipai/shared exec vitest run
src/app-definitions.test.ts`
- `pnpm --filter @paperclipai/server exec vitest run
src/services/paperclip-cloud-connector.test.ts
src/services/paperclip-cloud-connector-enrollment.test.ts`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts -t 'brokered Gmail
OAuth|brokered OAuth state'`
- `pnpm --filter @paperclipai/ui exec vitest run
src/pages/apps/Connections.test.tsx`
- `pnpm check:token-gates`
- `pnpm build`
- The full stable test runner also reproduced existing macOS workspace,
skill-discovery, and listener fixture failures outside the changed
paths. GitHub Linux CI is the authoritative full-suite result.
## Risks
- The managed flow depends on
https://github.com/paperclipai/paperclip-cloud/pull/312. Real provider
profiles stay disabled until Cloud deploys that protocol and the
provider approves the managed client.
- A Cloud outage blocks new authorization and refresh. Existing access
tokens continue to work until expiry.
- Managed Google profile removal only deletes the local grant. This
avoids invalidating the user's other profiles that share the managed
Google client.
- Legacy `paperclip_id_connector` records require a reconnect after
their current access tokens expire. Old Paperclip ID keys and refresh
tokens are not sent to Paperclip Cloud.

## 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.
> - Pi needs a separately spawned runtime whose executable does not yet
have the descriptor-confined verified launch used by the ACP server.
> - This pull request therefore activates Claude only and keeps Pi
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.

work.
> - Paperclip Runner provides a durable execution boundary for supported
providers.
> - The current production runtime supports Codex but cannot execute
OpenCode sessions.

the existing Codex path.
## 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
> - Recovery must re-admit the entire prospective session configuration
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
> - This pull request adds only that package-local projection without
selecting ACPX in runnerd
## 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

- The exact delta is 22 files, 1,206 additions, and 59 deletions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,

- `git diff --check` and the Cargo formatting check pass on the replayed
delta.

**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
independently reviewable
## 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.

- Stable patch ID: `b18d6b7efd1de569d3068b0a782f8aac2fbc9322`; this is
the prepared suspension delta plus the focused fake-sidecar fix that
consolidates mismatch modes into the existing command arm.
- The exact delta is 5 files, 136 additions, and 5 deletions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,

**PASSED**.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.
## 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

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

- Bound serialized responses to 768 KiB before validation.
- Require answer identifiers to match the exact persisted question set.
- Require answers for required questions and reject unknown question
identifiers.
- Enforce text, single-select, and multi-select answer modes.
- Match the existing TypeScript numeric syntax, including decimal,
exponent, hexadecimal, octal, and binary input.
- Match ECMAScript trimming exactly, including BOM whitespace while
rejecting Unicode NEL rather than inheriting Rust-specific whitespace
behavior.
- Enforce known options, custom-answer policy, text length, pattern, and
numeric constraints.
- 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
- Replay base: `7bb6cebeae727a16c205bb80b5c2b9e92ea6b5fa` (`master`

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.

## 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,

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.

checks: **PASSED** on the replayed exact head. Full CI run `33360832792`

## Risks
- This decoder is a security boundary because later code can act on
decoded semantic tool calls and input requests.
- It validates event authority before it inspects a payload.
- It fails closed on unknown runtime event types, malformed fields,
ambiguous question identifiers, unsupported terminal states, and
oversized payloads.
- It applies the existing durable redaction policy to retained values.
- The package exports a new Rust module, but no production path
constructs it in this pull request.
- A later provider adapter must preserve this validation order and must
not consume raw sidecar payloads directly.

## 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`

- 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`

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.

contract.

> - Separate adapter tests do not prove that both paths preserve the

## 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.

- This delta does not change dependencies, `pnpm-lock.yaml`, workspace
configuration, workflows, migrations, server selection, UI behavior, or

- 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.
- Security checks: **PASS** for the exact head. Superagent, Snyk, both
Socket checks, and contributor trust completed successfully.
- Greptile: **5/5** for the exact head, with no open P1/P2 findings,
recommendations, or follow-ups.
- No local test result is claimed. GitHub Actions is the authoritative
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.

## 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.

- 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
- Exact verified head: `dc89439d0b2e3dee46d212715caeefc8ae0c0959`.
- Full GitHub PR workflow passed in [run 33341468207, attempt
3](https://github.com/paperclipai/paperclip/actions/runs/33341468207/attempts/3),
including runner verification/build, typecheck, all test shards, canary,
and e2e.

- The diff contains 2 files and does not change `pnpm-lock.yaml`,
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.
