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

Runner rollout gate.
## 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
**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.

runtime did not expose the context-window size.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip Runner is an experimental execution adapter.
> - The adapter and its required sandbox ingress had separate settings.
> - A user could enable one setting and still have an unusable runner
configuration.
> - The runtime already makes one durable native or legacy decision for
each run.
> - This pull request uses that runtime decision for ingress
authorization.
> - The benefit is one clear opt-in with safe recovery for existing
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 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.

## 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.

## 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
or top PR.
- Greptile will review this exact delta after the branch is pushed.
## 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 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 is the open source app people use to manage AI agents for
work.
> - The Paperclip runner needs a safe boundary before it can launch
ACP-compatible agents.
> - A caller-controlled command, model, environment, or frame could
bypass that boundary.
> - The ACPX transport contract in #12386 defines the allowed messages
but does not bind a runtime profile.
> - This pull request defines closed, versioned profiles and validates
the launch inputs around that contract.
> - The benefit is a small and reviewable trust boundary before any ACPX
process can become available.
## Linked Issues or Issue Description
**Agent or provider**
ACPX sidecar support for the qualified Pi, Claude, and Codex ACP
servers.
**Why this adapter is useful**
The runner needs one bounded process boundary for ACP-compatible
providers. A closed profile prevents an untrusted run from selecting an
arbitrary executable, package version, or model.
**How the agent is invoked**
A later pull request will launch an internal sidecar from an exact
profile. This pull request only validates profiles, environment values,
and protocol frames. It does not add an executable dependency or enable
an adapter.
**Additional context**
This pull request is stacked on #12386. It keeps the existing direct
adapters and the Codex runner path unchanged.
## What Changed
- Add a closed profile table for the qualified Pi, Claude, and Codex ACP
servers.
- Require the exact qualified model and return an isolated profile value
to callers.
- Add an agent-specific environment allowlist with entry and aggregate
size limits.
- Add strict parsing for bounded sidecar requests and structured plan
values.
- Reject unknown fields, unsupported protocol versions, invalid
identifiers, null bytes, cyclic values, and oversized input.
## Verification
- Runner TypeScript typecheck — passed.
- Runner TypeScript tests — 40 files and 362 Vitest tests passed; 11
Node contract tests passed.
- `pnpm -r typecheck` — passed for all applicable workspaces.
- `pnpm build` — passed, including runner binary, server, UI, and
workspace packages.
- Prettier and `git diff --check` — passed.
- The diff contains 6 files and does not change `pnpm-lock.yaml`, a
workflow, a package dependency, or a public export.
## Risks
The main risk is accepting more launch state than the sidecar needs. The
implementation uses an agent-specific allowlist, rejects null bytes, and
enforces per-entry and aggregate bounds. This pull request does not
launch a process or expose a new adapter, so production and
direct-adapter behavior remain unchanged.
## Model Used
OpenAI Codex with GPT-5 and repository tool use.

## Linked Issues or Issue Description
Refs #11965
This is stack 7 of 11. It depends on stack 6 and replaces another
reviewable part of #11965.
## What Changed
- Add connection intent types, validation, service logic, and routes.
- Add agent runtime tools and CLI support for connection requests.
- Add issue-thread interaction support for connection intents.
- Add runtime, route, adapter, and contract tests.
- Hold the final resolved-continuation row lock through asynchronous
adapter preparation until an actual process spawn, so parking or
reassignment cannot cross that boundary.
- Report Hermes Gateway's first remote run request through the shared
dispatch hook so the resolved-intent lock is released at the true
dispatch boundary.
- Revalidate the addressed user's live non-viewer membership and
connection-management authority for every intent mutation, including
OAuth completion.
## Verification
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/tool-access-service.test.ts`
- Result: 176 tests passed.
- `pnpm build`
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/heartbeat-stale-queue-invalidation.test.ts` (32 passed;
includes non-process dispatch lock-release coverage)
- `pnpm exec vitest run --project @paperclipai/server
server/src/__tests__/connection-intents-service.test.ts -t
"addressed-user mutation"` (1 passed)
- `pnpm exec vitest run --project @paperclipai/server
server/src/__tests__/tool-access-service.test.ts -t "binds OAuth
callback completion to the initiating board session"` (1 passed)
- `pnpm --filter @paperclipai/hermes-paperclip-adapter test --
src/gateway/server/execute.test.ts` (23 passed; includes dispatch-hook
ordering and exactly-once coverage)
- `pnpm --filter @paperclipai/hermes-paperclip-adapter typecheck`
## Risks
- A malformed intent could create an unusable operator request.
- Validators and company checks reject invalid or cross-company
requests.
- The final continuation gate holds the issue row lock through adapter
preparation until process or remote dispatch; later operator changes use
the normal active-run interruption path.
- The change does not add a database migration.

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

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

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

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

## Linked Issues or Issue Description
**What happened?**
The remote process-session wrapper exited before it launched the agent
when the sandbox filesystem reported `birthtimeMs` as zero.
**Expected behavior**
The wrapper must start on a filesystem that does not report inode
creation time.
**Steps to reproduce**
1. Start the remote process-session wrapper.
2. Make `lstat()` report a zero `birthtimeMs` for its session directory.
3. Observe that the pre-fix wrapper terminates before the child process
starts.
**Paperclip version or commit**
Reproduced from `66e1c0df8b23cb8354b36dd446d9548dc4389191`.
**Deployment mode**
Self-hosted server with a remote sandbox runtime.
## What Changed
- Allow a zero reported creation time for process-session directories.
- Keep the probe that rejects a creation time copied from change time.
- Add a regression test that launches and stops a session with zero
birth time.
## Verification
- `npx vitest run
packages/adapter-utils/src/execution-target-stdin-race.test.ts`
- `pnpm --filter @paperclipai/adapter-utils typecheck`
## Risks
A filesystem without creation time can reduce the precision of
sandbox-local path-swap detection. This change does not change host-file
or Paperclip API authority. A follow-up will review that larger security
posture alignment.
> I checked `ROADMAP.md`. This is a focused compatibility bug fix for
the existing sandbox-agent roadmap area.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter runtime settles each run through a duplex control
channel
> - A lost channel can leave the remote session-close call without a
usable peer
> - The call has no deadline, so run teardown can wait for the full
adapter timeout
> - This pull request skips that remote call after the runtime latches
channel loss
> - The benefit is faster run finalization while the local cleanup
effects remain
## Linked Issues or Issue Description
**What happened?**
The run teardown placed a remote session-close call over a duplex
control channel that the runtime had already latched as lost. The call
blocked until the adapter execution timeout released it.
**Expected behavior**
Run teardown should release the local warm handle and continue when the
duplex control channel has already failed.
**Steps to reproduce**
1. Start an adapter run with the duplex control channel.
2. Latch a channel-loss state before settlement.
3. Use a runtime whose close call never resolves.
4. Confirm that teardown returns without a remote close call.
**Paperclip version or commit**
Commit d966069a78.
**Deployment mode**
Built from source.
**Agent adapter(s) involved**
Not adapter-specific. The change applies to the shared adapter runtime.
**Database mode**
Not database-related.
**Additional context**
Pull request #12373 used a larger approach for the same failure. The
board closed that pull request. This pull request contains the smaller
change.
## What Changed
- Add the required readonly `skipRemoteClose` field to the runtime
settlement plan.
- Set the field from the latched channel-loss state on the turn-finalize
plan.
- Set the field to `false` on every other settlement plan.
- Release the warm handle locally before the `end_session` step returns
without the remote call.
- Add a test that drives the lost-channel path through the settlement
sequence.
## Verification
- `./node_modules/.bin/tsc --noEmit -p packages/adapter-utils`
- `./node_modules/.bin/vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts` passes the new
test. Three existing tests fail on the merge base: two
session-fingerprint tests and one workspace-hints test.
- `./node_modules/.bin/vitest run
packages/adapter-utils/src/acpx-engine/run-fault-matrix.test.ts` reports
20 passed.
- Full CI will run on this pull request.
## Risks
The skipped remote close also skips the vendored runtime caller for
`closeBackendSession`. The run can keep a retained client after duplex
loss. A separate follow-up owns that residual. The environment lease
still releases in the teardown `finally` block.
## Model Used
OpenAI Codex, GPT-5, with tool use and code review assistance.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Adapter utilities transfer files between the host and an agent
environment
> - A sandbox target already provides the security boundary for inbound
files
> - The generic fallback adds a temporary file and a rename that do not
add protection inside that boundary
> - This pull request writes a mode-constrained inbound file directly to
its target and applies the mode after the write
> - The benefit is a simpler transfer path while host targets keep the
strict pre-write mode rule
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The inbound file-sync fallback for a mode-constrained file stages the
file under a temporary name, applies the mode, and renames the file into
place.
**Subsystem affected**
`packages/adapter-utils` and `packages/plugins`.
**Current behavior**
A sandbox target uses a temporary path before it receives the file. The
host then changes the mode and renames the file to the target path.
**Proposed behavior**
A sandbox target receives the file at its target path. The host applies
the mode after the write. A host target still applies the mode before
the first byte.
**Reason and benefit**
The sandbox boundary already protects the target. The direct write
removes an unnecessary staging path and rename.
**Breaking changes**
None. The directory path and outbound transfer path keep their existing
behavior.
## What Changed
- Write a mode-constrained single-file inbound transfer directly to the
sandbox target.
- Apply the mode after the direct write and keep the confinement check
before post-upload commands.
- Scope the protocol comment by transfer direction and preserve the
strict host-target rule.
- Keep directory inbound transfers and outbound transfers unchanged.
## Verification
- Run the targeted unit suite for the changed package.
- Verify the suite covers direct target writes, post-write mode
application, and confinement rejection.
- Run `tsc --noEmit` for both changed packages.
- Review the full GitHub Actions check set after the PR opens.
## Risks
- A sandbox provider that assumes a temporary inbound path could expose
a behavior mismatch.
- The confinement check remains before post-upload commands, which
limits escape risk.
- Host targets keep the pre-write mode rule, so host permission behavior
does not change.
## Model Used
OpenAI GPT-5. This model assisted with Git operations, PR preparation,
review coordination, and tool use. Context window size and reasoning
mode are not exposed by the runtime.

work.

environments.
> - The remote process-session wrapper uses a probe file to verify
directory creation time.

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

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

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

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters use SSH environment fixtures to test process behavior
> - The SSH fixture detached its listener process from the test process
> - Teardown removed the fixture directory without stopping and awaiting
that listener
> - This pull request validates fixture state, stops the listener with

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

## Linked Issues or Issue Description
**What happened?**
The referenced-project ignore scan trimmed NUL-delimited Git paths. It
also accepted a large ignored-path set and exposed raw failure details
through staging errors and warnings.
**Expected behavior**
The scan must preserve leading and trailing whitespace in Git paths. It
must reject oversized ignored-path data and expose only fixed failure
categories.
**Steps to reproduce**
1. Run the referenced-project ignore scan with paths that start or end
with whitespace.
2. Provide more than 10,000 ignored entries or more than 2 MiB of path
bytes.
3. Trigger a scan failure and inspect the reported reason.

**Deployment mode**
Built from source.
**Installation method**
Built from source.
**Agent adapter(s) involved**
Not adapter-specific.
**Database mode**
Not database-related.
**Additional context**
This change covers the overlay diff, untracked, deleted, and ignored Git
paths. It also retries only typed scheduler saturation failures.
## What Changed
- Preserve all bytes in NUL-delimited Git path records.
- Bound ignored-entry count and total UTF-8 path bytes during parsing.
- Redact scan failure details to three fixed reason categories.
- Retry only the typed scheduler saturation error, with three total
attempts and 1 second then 2 second waits.
- Add tests for path whitespace, limits, diagnostics, retry behavior,
and scheduler code parity.
## Verification
- `npx tsc --noEmit` in `packages/adapter-utils` passed.
- `npx vitest run packages/adapter-utils` passed with 977 tests and 4
skipped.
- Continuous integration must run the server suite and the full
repository gates.
## Risks
The scan now rejects ignored-path data above fixed limits. Saturation
retries add up to 3 seconds before a final failure. The resolver still
fails closed for all other errors.
## Model Used

## Linked Issues or Issue Description
Refs #7029
Refs #12138
Refs #12147
**What happened?**
A skill-capable legacy local agent could start without
`paperclipai/paperclip/paperclip`. This happened when the agent had no
stored skill preference. An explicit empty preference also removed the
skill. The agent then reported that the Paperclip skill was not
available.
**Expected behavior**
Every skill-capable legacy local adapter must mount the Paperclip
operational skill when the runtime inventory contains it. Optional
skills must remain configurable. The native runner must keep its current
protocol-based behavior.
**Steps to reproduce**
1. Create a non-CEO `codex_local` agent without `paperclipSkillSync`
preferences.
2. Start a legacy heartbeat.
3. Inspect the managed `CODEX_HOME/skills` directory.
4. Observe that the Paperclip skill is absent before this change.
**Paperclip version or commit**
The problem reproduces on `master` before this pull request. PR #7029
introduced the configured-only selection behavior.
**Deployment mode**
Local development and self-hosted legacy local adapters.
## What Changed
- Added a shared legacy skill resolver that always selects the canonical
Paperclip operational skill when it is available.
- Applied the resolver to direct adapter execution, ACPX execution,
skill snapshots, and persistent skill sync.
- Added Hermes skill materialization at sync and run boundaries.
- Aligned Cursor, Gemini, and OpenCode execution-time injection with the
configured child `HOME`.
- Made Hermes stop execution when another installation blocks the
required operational skill.
- Kept optional skills controlled by `paperclipSkillSync.desiredSkills`.
- Kept `paperclip_runner` on the configurable-only resolver.
- Added regression coverage for missing preferences, empty preferences,
each skill-capable legacy adapter, ACPX, Hermes, and native runner
isolation.
- Documented the legacy runtime invariant.
## Verification
- `pnpm -r typecheck` passed on the pushed commit.
- `pnpm build` passed on the pushed commit.
- The adapter utility regression suites passed: 236 tests.
- The changed server adapter suites passed: 48 tests across 12 files.
- The OpenCode adapter suite passed: 8 tests.
- The Hermes adapter suite passed: 7 tests.
- `git diff --check` passed.
- `pnpm test:run` is not clean on this macOS host. The command reported
failures in unchanged workspace and filesystem suites. An isolated rerun
of `company-skills.test.ts` and `company-skills-service.test.ts`
reproduced 11 failures because macOS resolved `/var/...` paths as
`/private/var/...`. The changed adapter suites pass independently.
## Risks
- This change deliberately makes the operational skill non-removable for
skill-capable legacy local adapters.
- Existing agents receive the skill on their next list, sync, or run
boundary. No database migration is required.
- The resolver does not create a skill when the runtime inventory does
not contain the canonical entry.
- Hermes aborts a run if another installation occupies the required
operational skill target.
- Hermes removes only an undesired Paperclip-owned symlink that still
points to the known Paperclip source.
- The native runner does not receive the legacy default.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent adapters run workspace restore steps when an ACP run ends.
> - Claude, Codex, and Gemini each kept a near-identical teardown
closure.
> - Duplicate closures require the same defect fix in three files.

and keeps each adapter's message strings.

and outcome for all three adapters.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The Claude, Codex, and Gemini ACP adapters restore the workspace during
teardown and report restore failures with an allowlisted message.
**Subsystem affected**
`packages/adapters/` and `packages/adapter-utils/`.
**Current behavior**
Each adapter keeps a near-identical closure. The closure logs a start
line, restores the workspace, classifies errors, and logs a fixed
failure line.
**Proposed behavior**
A shared `createWorkspaceRestoreTeardown` factory owns the common steps.
Each adapter passes its staged runtime, log sink, start line, and
failure prefix.
**Reason and benefit**
The shared factory removes duplicate error handling. One tested
implementation now preserves the existing output and outcome for all
three adapters.
**Breaking changes**
None. The refactor preserves the emitted lines and returned outcomes.
**Additional context**
This pull request contains no public issue reference because no related
public issue was found.
## What Changed
- Add `createWorkspaceRestoreTeardown` to `packages/adapter-utils`.
- Move the shared restore, classify, and allowlisted log flow into the
factory.
- Update the Claude, Codex, and Gemini ACP adapters to call the factory.
- Add a table-driven test for all three message pairs.
- Keep one end-to-end restore-failure regression test per adapter.
## Verification
- `pnpm --filter @paperclipai/adapter-claude-local typecheck`
- `pnpm --filter @paperclipai/adapter-codex-local typecheck`
- `pnpm --filter @paperclipai/adapter-gemini-local typecheck`

- `npx vitest run packages/adapters/codex-local/src/server/acp.test.ts`
- `npx vitest run packages/adapters/gemini-local/src/server/acp.test.ts`
- Continuous integration must pass before merge, except for the known
pre-existing failures listed in the handoff.
## Risks
Low risk. This change moves shared code without changing behavior. The
adapter-specific message strings remain unchanged.
## Model Used
OpenAI GPT-5, exact model ID `gpt-5`, tool use and code review
assistance. The context window size was not provided by the runtime.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Referenced projects are staged into run sandboxes, and a recent
change made each staging site resolve the project's Git-ignored paths
explicitly (`ignoreResolution` on `SandboxAdditionalSource`)
> - One test call site was left without the now-required property, so
`tsc` fails in adapter-utils and every Build/Typecheck CI job on master
is red (surfaced when the TypeScript 7 bump landed in the same window)
> - Separately, the new descendant check compares a logical caller path
against the physical toplevel git prints, so any symlinked path fails
ignore resolution spuriously — three of the suite's own tests fail on
macOS because temp dirs live under the `/var` → `/private/var` symlink
> - This pull request supplies the missing property at the test call
site and makes the descendant comparison symlink-safe via realpath on
both sides
> - The benefit is a green master again, plus referenced-project staging
that works from symlinked checkouts and temp directories
## Linked Issues or Issue Description
No public issue exists; the underlying problem follows the bug-report
template.
**What happened?**
`packages/adapter-utils` fails `tsc` on master:
`src/sandbox-managed-runtime.test.ts(2284,29): error TS2741: Property
'ignoreResolution' is missing in type '{ localPath: string; projectId:
string; }' but required in type 'SandboxAdditionalSource'.` Every
Build/Typecheck CI job is red. Independently,
`resolveReferencedSourceIgnore` returns `{ kind: "failed", reason:
"referenced project path is not a descendant of its own Git top level:
/var/... under /private/var/..." }` for any symlinked project path, and
three tests in the suite fail on macOS.
**Expected behavior**
Master typechecks. A referenced project whose path reaches git through a
symlink (macOS temp dirs, symlinked checkouts) resolves its ignore set
normally, and the descendant check still fails closed for genuinely
foreign paths.
**Steps to reproduce**
1. `pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit` on
master — TS2741 at `sandbox-managed-runtime.test.ts:2284`.
2. On macOS: `pnpm vitest run
packages/adapter-utils/src/sandbox-managed-runtime.test.ts` — three
`resolveReferencedSourceIgnore` tests fail with the "not a descendant"
reason above.
**Paperclip version or commit**
master `29d12045f`.
## What Changed
- `sandbox-managed-runtime.test.ts:2284`: the one call site missing
`ignoreResolution` now passes `{ kind: "other" }`, matching every
sibling call site from the same change.
- `sandbox-managed-runtime.ts`: `resolveReferencedSourceIgnore` resolves
both the git toplevel and the caller's `localPath` through a new
`physicalPath` helper (realpath with a resolve fallback) before the
descendant comparison. Git prints physical toplevels, so both sides must
be physical; the fallback keeps the check failing closed when a path
vanishes mid-run.
## Verification
- `pnpm vitest run
packages/adapter-utils/src/sandbox-managed-runtime.test.ts` — 61/61 pass
on macOS (previously 58 passing, 3 failing, plus the typecheck break).
- `tsc --noEmit` in `packages/adapter-utils` is clean.
## Risks
- Low. The behavioral change is confined to path normalization before an
existing comparison; a realpath failure falls back to the prior string
comparison, so the fail-closed property is preserved.
## Model Used
Claude Fable 5 (`claude-fable-5`, Anthropic) via Claude Code — agentic
coding session with tool use (code search, editing, local test
execution).

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Sandbox agents send callback requests through a generated gateway.
> - The HTTP/2 callback path converts each full request body to a UTF-8
string.
> - The same path converts that string back to a buffer before it sends
the request.
> - This pull request sends the body buffer directly to the HTTP/2
forwarder.
> - The benefit is less copying and unchanged queue payload behavior.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The sandbox callback gateway HTTP/2 send path copies the full request
body through a UTF-8 string before it sends the body.
**Subsystem affected**
The affected subsystem is `packages/adapter-utils`, which contains
sandbox gateway and HTTP/2 adapter utilities.
**Current behavior**
The gateway reads the body into a buffer, converts the complete body to
a UTF-8 string, and converts that string back to a buffer for the HTTP/2
path. The queue path stores the string payload.
**Proposed behavior**
The gateway keeps a byte reader for the HTTP/2 path. A thin text wrapper
keeps the queue path behavior. The HTTP/2 path sends the original body
buffer.
**Reason and benefit**
The extra conversions add work and memory use without changing the
HTTP/2 body bytes. Direct buffer forwarding removes that work and
preserves the size limit and reject behavior.
**Breaking changes**
None. The queue payload remains a string. The body size limit, content
type check, and reject point remain unchanged.
**Additional context**
This change has no public issue link. The repository roadmap search
found no duplicate planned work. The implementation also adds tests for
non-ASCII JSON, malformed UTF-8, size limits, and queue payload shape.
## What Changed
- Add `readBodyBytes(req)` for byte-preserving body reads.
- Keep `readBody(req)` as a string wrapper for the queue path.
- Send the byte buffer directly on the HTTP/2 path.
- Add tests for byte identity, malformed UTF-8, size limits, and queue
payload shape.
## Verification
- `pnpm --filter @paperclip/adapter-utils test
src/sandbox-callback-bridge.test.ts` passed with 51 tests.
- `pnpm --filter @paperclip/adapter-utils exec tsc --noEmit` passed.
- The tests spawn the generated gateway and the real host HTTP/2 bridge.
- The tests verify byte identity, malformed UTF-8, pre-forward size
rejection, queue file protection, and string queue payloads.
- Full repository CI must pass before merge.
## Risks
Low risk. The HTTP/2 path changes its internal body conversion only. The
queue path keeps the prior string payload. The size limit and reject
point stay unchanged.
## Model Used
OpenAI Codex, GPT-5, tool use and code review assistance. The exact
runtime context window is managed by the Codex service.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter utilities package provides transport code for sandbox
agents
> - The retired `duplex_v1` broker no longer produces or consumes
body-chunk frames
> - Dead protocol code remains in the host codec, gateway copy, bridge
options, and tests
> - This pull request removes that dead code and keeps the READY
handshake unchanged
> - The benefit is a smaller transport surface with fewer unused paths
to maintain
## Linked Issues or Issue Description
**What existing behavior does this improve?**
This change improves the adapter utilities code that supports sandbox
duplex readiness and frame handling.
**Subsystem affected**
`packages/adapter-utils/` — sandbox transport codecs, execution targets,
and callback bridge tests.
**Current behavior**
The repository keeps body-chunk frame types, validators, a body spool,
decoder limits, and tests after the `duplex_v1` broker removal. No live
producer or consumer uses this code.
**Proposed behavior**
Remove the unused body-chunk protocol code and retain the READY
handshake, its strict checks, and its size limits.
**Reason and benefit**
The removal reduces dead code and keeps the host and embedded gateway
paths easier to inspect. It adds no new behavior.
**Breaking changes**
The removed frame types now decode as `unknown_type`. The live readiness
gate already ignores those frames. The READY handshake stays
byte-for-byte compatible.
**Additional context**
This cleanup follows [PR
#12171](https://github.com/paperclipai/paperclip/pull/12171), which
removed the duplex broker.
## What Changed
- Remove `duplex-body-spool.ts` and its test.
- Remove unused body-chunk frame types, validators, decoder code,
vectors, and limits.
- Remove the unused `reassembledBody` option and decoder limit
environment entry.
- Remove the embedded gateway decoder copy and the unused frame type
map.
- Keep the READY handshake and its existing boundary tests unchanged in
behavior.
## Verification
- `pnpm -F @paperclip/adapter-utils typecheck` passes.
- The duplex frame codec test passes with 30 tests.
- The sandbox execution-target test passes with 136 tests.
- The sandbox callback bridge test passes with 46 tests.
- CI must confirm all required checks after it starts.
## Risks
Low risk. The change removes code only. The READY handshake, HTTP/2 body
path, and byte-ledger path remain unchanged.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters restore sandbox work into project workspaces after a
run
> - The restore lock used the target workspace parent, which can reject
writes
> - The teardown then hid restore errors, so a run could report success
with lost work
> - This pull request moves the lock into an instance-scoped root and
reports safe restore failure codes
> - The benefit is reliable restore coordination and visible failure
evidence without changing run success semantics
## Linked Issues or Issue Description
Refs: #10914
## What Changed
- Move the workspace-restore merge lock into a private, instance-scoped
root.
- Derive the lock key from the canonical target path with SHA-256.
- Resolve the lock root from the caller environment and reject unsafe
root types.
- Classify restore failures with three allowlisted codes.
- Add the failure code to run result JSON without exposing a host path
or process identifier.
- Keep restore failure fail-open for the run exit code and run status.
## Verification
- Run `npx vitest run
packages/adapter-utils/src/workspace-restore-merge.test.ts`.
- Run `npx vitest run
packages/adapter-utils/src/acpx-engine/run-fault-matrix.test.ts`.
- Run the four Codex credential suites.
- Confirm the branch includes the current `master` commit and no manual
lockfile edit.
- Confirm all pull request checks and the Greptile review reach a
terminal green state.
## Risks
- The lock path changes for workspace restore and removes the
sibling-directory fallback.
- A misconfigured or inaccessible instance home can still stop lock
setup.
- Restore remains fail-open, so callers must inspect the result evidence
when a restore fails.
## Model Used
OpenAI GPT-5. The model used tool calls and code execution to validate
and route an author-provided change. The implementing engineer authored
the code.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters move files between the host and sandbox during a run
> - The sync transport reports transferred bytes, but some progress
lines discard this value
> - Discarded byte totals make large transfers display as `0.0 MB`
> - This pull request passes the transport total to the affected
progress lines
> - The benefit is accurate transfer progress without changing file
movement or confinement checks
## Linked Issues or Issue Description
**What happened?**
Three file-sync progress lines displayed `0.0 MB` when the transport
moved data. The affected paths cover referenced-project staging, native
git-history export, and native workspace restore.
**Expected behavior**
Each progress line should display the bytes that the sync transport
transfers. A provider that reports zero bytes should preserve the known
host-side value for inbound workspace sync.
**Steps to reproduce**
1. Run a sandbox task that stages a referenced project.
2. Run a task that uses native git-history export or native workspace
restore.
3. Inspect the file-sync progress lines during each transfer.
**Paperclip version or commit**
Commit `8062612baa20036a1defce8bbd683c038ba187d5`.
**Deployment mode**
Built from source with the adapter-utils Vitest suite.
## What Changed
- Add a helper that sums valid `bytesTransferred` values from a
`SandboxSyncResult`.
- Use the transport total for referenced-project staging, native
git-history export, and native workspace restore.
- Preserve the caller count when referenced-project staging reports zero
bytes.
- Add tests for non-zero progress and the zero-byte fallback.
## Verification
- Run `npx vitest run
packages/adapter-utils/src/sandbox-managed-runtime.test.ts` from the
repository root.
- Run the TypeScript check for `packages/adapter-utils`.
- Confirm that the new tests cover referenced-project staging, native
workspace restore, native git-history export, and the zero-byte
fallback.
## Risks
This change affects progress reporting only. It does not change
transferred files, transfer order, provider behavior, or confinement
checks.
## Model Used
OpenAI Codex, GPT-5, with tool use and code execution. The model
reviewed and routed the author-provided change. The implementing
engineer authored the code.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Sandbox adapters stage project files before an agent starts.
> - Referenced projects ignored Git-ignored paths and copied large local
directories.
> - This behavior increased staging time and disk use, and it differed
from anchor workspaces.
> - This pull request resolves Git-ignored paths once and shares that
result across all referenced-project consumers.

## Linked Issues or Issue Description
No public GitHub issue exists for this bug.
**What happened?**
Referenced-project staging copied Git-ignored paths, except for a fixed
list of heavy directory names. A large repository therefore used much
more time and disk space than the same repository in an anchor
workspace.
**Expected behavior**
Referenced-project staging should exclude the same Git-ignored paths
that the workspace staging path excludes.
**Steps to reproduce**
1. Create a referenced project with a large Git-ignored directory.
2. Start a sandbox or SSH run that stages the referenced project.
3. Observe that the ignored directory enters the staged content.
**Paperclip version or commit**
Commit `9964b034bbff24e700c8eccf5a8b1fc3daa44bf2`.
**Deployment mode**
Built from source.
## What Changed
- Resolve each referenced project's Git-ignored paths once before
staging.
- Carry the resolved paths as a required field on
`SandboxAdditionalSource`.
- Reuse the resolved paths in sandbox staging, SSH staging, and
content-signature code.
- Harden the read-only Git helper with a bounded process, a reduced
environment, and disabled system and global configuration.
- Fail closed on Git errors, timeouts, and invalid path relations.
- Escape tar glob metacharacters in ignore-derived exclude entries.
- Add and update unit tests for the resolver and its three consumers.
## Verification
- `pnpm vitest run --config packages/adapter-utils/vitest.config.ts`
passes 266 tests locally.
- `pnpm exec tsc --noEmit -p packages/adapter-utils/tsconfig.json`
passes locally.
- CI must pass on this pull request.
- Greptile must report 5/5 with no unresolved comments before merge.
## Risks
- A Git error or timeout now prevents staging for the affected
referenced project.
- The resolver uses a bounded read-only Git process and fails closed by
design.
- The change stays inside `packages/adapter-utils` and does not change
the database schema.
## Model Used
Claude Sonnet 5 (Anthropic) assisted the implementation with code
execution and tool use. The exact context window and reasoning mode are
not recorded.

## Linked Issues or Issue Description
**What existing behavior does this improve?**
How agents reason about the company skill library at runtime.
**Subsystem affected**
`packages/adapter-utils` (new pure builder),
`packages/adapters/claude-local` (instructions append),
`packages/mcp-server` (new tool).
**Current behavior**
The runtime hands adapters the full library list, but only the agent's
enabled skills are mounted, and no prompt content or MCP tool describes
the rest. Agents inspect their sandbox, find nothing, and report
installed skills as not installed.
**Proposed behavior**
A "Company skill library" markdown section lists every skill as
`enabled`, `installed, not enabled for you`, or `enabled but
unavailable: <cause>`, with instructions to report the not-enabled state
accurately and ask an operator to enable it. claude-local appends it to
the agent instructions text. A `paperclipListSkills` MCP tool exposes
the same list on demand.
**Breaking changes**
None. Other adapters are untouched (they can adopt the builder later);
the manifest is deterministic, so the claude-local prompt-bundle cache
only busts when the library actually changes.
## What Changed
- New `packages/adapter-utils/src/skill-library-manifest.ts` with
`buildSkillLibraryManifestMarkdown` (pure, key-sorted, deterministic;
renders the missing-cause detail from #12146).
- `packages/adapters/claude-local/src/server/execute.ts` appends the
manifest to `combinedInstructionsContents` (creating it when no
instructions file is configured).
- `packages/mcp-server/src/tools.ts` adds `paperclipListSkills` hitting
`GET /companies/:companyId/skills`.
## Verification
- `npx vitest run
packages/adapter-utils/src/skill-library-manifest.test.ts` (from repo
root) — 3 tests: byte-identical output for shuffled input, state
rendering incl. the unavailable cause, change detection.
- `cd packages/mcp-server && npx vitest run` — new tool routing test
passes (13 passed; 1 pre-existing failure on my machine reproduces
unchanged at the branch base).
- `cd packages/adapters/claude-local && npx vitest run` — 244 passed, 1
skipped.
- `pnpm run typecheck` clean in adapter-utils, mcp-server, claude-local.
## Risks
- Prompt growth is one line per installed skill plus a five-line header
— bounded and only present when the library is non-empty. Stacked on
#12146 so the manifest's "enabled but unavailable" state reflects real
materialization failures.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Runtime skill listing materializes each company skill's files before
handing them to the agent's adapter
> - A materialization failure was swallowed with catch-to-null, and the
skill silently vanished from the runtime while the library still showed
it installed
> - Operators saw "installed", agents saw nothing, and nobody saw the
cause; on claude-local a missing desired skill could even crash the
prompt-bundle hasher
> - This pull request turns both failure paths into structured "missing"
entries with the real error and makes every adapter skip unmountable
entries explicitly
> - The benefit is that a broken skill shows up as broken, with its
cause, instead of not existing
## Linked Issues or Issue Description
**What happened?**
A company skill whose runtime files fail to materialize (deleted source,
missing stored SKILL.md copy, failed version snapshot) disappears from
`listRuntimeSkillEntries` with no trace. Agent skill snapshots report a
generic "not available" with no cause. On claude-local, a desired skill
whose source path does not exist reaches the prompt-bundle hasher, whose
`fs.lstat` throws and can fail the whole run.
**Expected behavior**
The skill appears with `sourceStatus: "missing"` and a `missingDetail`
carrying the underlying error, snapshots and the UI show it as broken,
and adapters skip it at mount time with a logged warning instead of
crashing or dangling-symlinking.
**Steps to reproduce**
Install a local-path skill referenced by an agent, delete its source
directory contents so the stored SKILL.md copy cannot be recovered, and
start a run: before this change the skill vanishes from the runtime set
silently; on claude-local a pinned-but-unmaterializable version can fail
bundle preparation.
## What Changed
- `server/src/services/company-skills.ts` `resolveRuntimeSkillSource`:
both `.catch(() => null)` sites (version snapshot, runtime
materialization) now return the structured `{status: "missing", source,
detail}` shape the deliberate missing branch already used, with the
underlying error message in `detail`.
- `packages/adapter-utils/src/server-utils.ts`:
`isPaperclipSkillSourceMissing` is exported with a doc comment.
- `packages/adapters/claude-local/src/server/execute.ts`: missing
desired skills are filtered out of the prompt bundle and each one logs a
`[paperclip] Warning` with its detail to the run output.
- `cursor-local`, `gemini-local`, `kimi-local`, `opencode-local`,
`pi-local` `execute.ts`: mount loops (and the cursor/gemini injection
calls) skip missing entries instead of symlinking a nonexistent path.
## Verification
- `cd server && npx vitest run
src/__tests__/company-skills-service.test.ts` — new test pins the
missing-with-cause entry for a failed materialization. Nine pre-existing
project-workspace tests in this file fail on my machine at clean
`master` too (environment-specific); their count is unchanged by this
PR.
- `cd server && npx vitest run
src/__tests__/heartbeat-runtime-skills.test.ts
src/__tests__/claude-local-skill-sync.test.ts
src/__tests__/cursor-local-skill-sync.test.ts
src/__tests__/cursor-local-skill-injection.test.ts
src/__tests__/gemini-local-skill-sync.test.ts` — 12 tests pass.
- `cd packages/adapters/claude-local && npx vitest run` — 244 passed, 1
skipped.
- `pnpm run typecheck` clean in server, adapter-utils, and all six
touched adapters.
## Risks
- Runtime skill entry lists grow by the previously dropped entries (now
flagged missing). All shipped consumers either intersect with desired
sets, already handle `sourceStatus: "missing"`, or now skip missing
entries at mount time. The snapshot layer already understood the missing
shape via the `materializeMissing: false` path, so downstream contracts
are unchanged.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter utilities provide sandbox transport paths for agent
execution
> - The retired `duplex_v1` path remains in host, gateway, and test code
after `http2_v1` replaced it
> - Retired transport code adds maintenance cost and leaves an unsafe
fallback for unknown gateway modes
> - This pull request removes the retired path, moves shared `http2_v1`
contracts to a leaf module, and closes mode dispatch to a fixed
allowlist
> - The benefit is a smaller transport surface and explicit failure for
unsupported modes
## Linked Issues or Issue Description
Refs #12120
The `http2_v1` transport replaced `duplex_v1`, but the retired broker,
gateway, constants, and tests remain in the adapter utilities. An
unknown bridge mode can also fall through to the queue gateway when a
queue directory exists. This change removes the retired code and rejects
unsupported modes before gateway selection.
## What Changed
- Delete the host `duplex_v1` broker and its transport-only tests.
- Delete the in-sandbox duplex gateway and retired mode constants.
- Move shared `http2_v1` symbols into `bridge-transport-contract.ts`.
- Update the remaining importers and repair their focused tests.
- Validate bridge modes against `http2_v1` and `queue_v1` before queue
lookup.
- Keep `queue_v1`, `duplex-frame-codec.ts`, and duplex telemetry
dimensions unchanged.
## Verification
- [x] `npx tsc --noEmit -p packages/adapter-utils` passes.
- [x] `npx vitest run packages/adapter-utils/src` passes: 48 files and
968 tests pass, with 4 pre-existing platform skips.
- [x] Full CI is green on this pull request.
- [x] Greptile review is complete and every finding is resolved.
## Risks
The change removes an internal transport that no host path selects. The
main risk is an overlooked import or test dependency. Targeted typecheck
and tests cover the adapter utility package. Full CI must confirm
workspace-wide compatibility.
## Model Used
Anthropic Claude Sonnet 5 assisted with the implementation, as recorded
in the commit. The commit does not record a context-window size or
reasoning mode.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters use the HTTP/2 bridge to carry requests and responses
> - The bridge has an idle bound and a total-lifetime ceiling for
request bodies
> - The old renewable lifetime bound re-armed with each DATA chunk and
could not act before the idle bound
> - The code also repeated the same bounds and rationale in several
places
> - This pull request removes the unreachable renewable bound, keeps the
one-shot ceiling, and simplifies the shared bounds object
> - The benefit is clearer protection logic with the same default
request-body behavior
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The HTTP/2 bridge request-body reader uses several repeated bound
parameters and comments. One renewable lifetime bound cannot act before
the idle bound under the shipped defaults.
**Subsystem affected**
`packages/adapter-utils/` — HTTP/2 bridge adapter utilities.
**Current behavior**
The idle bound and renewable lifetime bound both re-arm after each DATA
chunk. The renewable bound therefore does not act on its own. The
total-lifetime ceiling also shares timer setup with the renewable bound.
**Proposed behavior**
Remove the renewable lifetime bound. Keep the total-lifetime ceiling as
an independent one-shot timer. Pass one bounds object to the bridge call
sites and keep tests for the idle bound and total-lifetime ceiling.
**Reason and benefit**
The change removes unreachable logic and repeated rationale. It keeps
the independent total-lifetime protection and makes the bound behavior
easier to review.
**Breaking changes**
The change removes two public constant and option names that
repository-wide search found unused outside this implementation. The
shipped default behavior does not change.
## What Changed
- Remove the renewable request-body lifetime bound and its public names.
- Keep the total-lifetime ceiling as a one-shot timer that starts when
the body read starts.
- Replace repeated bound parameters with one `Http2BridgeBodyBounds`
object.
- De-duplicate bound rationale comments.
- Add shared test helpers and update tests for the idle bound and
total-lifetime ceiling.
## Verification
- Run `npx tsc --noEmit -p packages/adapter-utils`.
- Run `npx vitest run
packages/adapter-utils/src/http2-bridge-server.test.ts`.
- Wait for the pull request CI checks.
- Request the Greptile review and confirm a 5/5 verdict with no open
findings.
## Risks
The main risk is an incorrect timer lifetime after the renewable timer
removal. The one-shot ceiling remains independent, and the updated tests
cover its expiry and cleanup paths. The change does not alter the
shipped default bounds.
## Model Used
OpenAI Codex based on GPT-5. Exact runtime model version is GPT-5. The
work used tool calls and code execution for repository inspection and
GitHub operations.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox providers carry agent work through controlled execution
channels
> - The Daytona callback bridge uses a bespoke line-framed protocol over
its duplex channel
> - The bespoke protocol adds framing work and does not use the Node
transport that already supports multiplexed streams
> - This pull request carries raw bytes across the channel, adds a Node
HTTP/2 bridge, and selects it for Daytona
> - The benefit is one authenticated, multiplexed callback session with
queue_v1 as the bounded fallback
## Linked Issues or Issue Description
**Subsystem affected**
The packages/plugins Daytona provider and the shared duplex execution
path.
**Problem or motivation**
The Daytona callback bridge uses a bespoke line-framed protocol over the
provider duplex channel. This adds protocol work and limits stream
handling.
**Proposed solution**
Carry raw bytes through the cross-layer channel. Add an authenticated
Node HTTP/2 host server and sandbox client gateway. Select http2_v1 for
Daytona and retain queue_v1 as the fallback.
**Alternatives considered**
Keep the current duplex_v1 protocol. This keeps the bespoke framing path
and does not provide one HTTP/2 session for callback streams.
**Roadmap alignment**
ROADMAP.md lists Daytona under cloud and sandbox agents. This change
improves the shipped Daytona provider path.
**Additional context**
The branch adds no dependency. Node 24 provides the http2 module. The
host token check and canonical path parser remain the single dispatch
path.
## What Changed
- Carry raw Uint8Array chunks through the adapter, plugin, worker,
runtime, and Daytona layers.
- Encode bytes as base64 only across the JSON-RPC hop, because JSON has
no binary type.
- Add the bounded host HTTP/2 server and the in-sandbox HTTP/2 client
gateway.
- Authenticate every stream with the per-run bridge token before route
work.
- Parse the path once and reuse the canonical result for route and
forwarding work.
- Select http2_v1 for Daytona and fall back once to queue_v1 when the
client preface is absent.
- Add transport, session, stream, and fallback telemetry.
- Mark HTTP/2 as the preferred transport and queue_v1 as the
soft-deprecated fallback.
## Verification
- `npx vitest run packages/adapter-utils/src` — 990 passed and 4
skipped.
- `npx vitest run
server/src/__tests__/plugin-worker-manager-duplex.test.ts` — 32 passed.
- `npx vitest run --config
packages/plugins/sandbox-providers/daytona/vitest.config.ts` — 220
passed and 6 skipped.
- `npx tsc --noEmit` in `packages/adapter-utils`, `packages/shared`,
`packages/plugins/sdk`, and `server` — clean.
- No `package.json` or `pnpm-lock.yaml` file changed.
- The live Daytona test skips when `DAYTONA_API_KEY` is absent.
- The root `npx tsc --noEmit` command has a pre-existing missing
`packages/adapters/droid-local` reference on this branch and on
`master`.
## Risks
- The transport change affects several duplex layers and could expose
byte-boundary errors.
- A missing HTTP/2 client preface falls back once to queue_v1 and
records `preface_missing`.
- The host token check and canonical path parser must remain on the
shared dispatch path.
- The live Daytona test needs `DAYTONA_API_KEY` and does not run in this
agent sandbox.
## Model Used
OpenAI GPT-5, tool-enabled coding agent with repository inspection,
GitHub CLI, and shell execution.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter utilities package defines shared types for agent
execution targets
> - The type name EffectiveSandboxCapabilities describes only one
transport
> - All execution target drivers return the same resolved capability
snapshot
> - This pull request gives the snapshot a general name and keeps the
old type as a deprecated alias
> - The benefit is clearer public vocabulary with source compatibility
for current consumers
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The exported capability snapshot type uses the name
`EffectiveSandboxCapabilities`, although local, SSH, sandbox, and plugin
drivers return it.
**Subsystem affected**
The change affects `packages/adapter-utils` and its server consumers.
**Current behavior**
The public type name points to the sandbox transport. The private parser
also uses the sandbox-only name.
**Proposed behavior**
Use `EffectiveExecutionCapabilities` for the public type and
`parseEffectiveExecutionCapabilities` for the private parser. Keep a
deprecated alias for the old public type.
**Reason and benefit**
The new name matches the established execution-target vocabulary. The
alias keeps existing type imports working during the migration.
**Breaking changes**
None. The runtime field, capability flags, parsed shape, and package
versions do not change.
**Additional context**
GitHub search found no duplicate or related open issue or pull request.
## What Changed
- Rename the exported interface to `EffectiveExecutionCapabilities`.
- Keep `EffectiveSandboxCapabilities` as a deprecated type alias.
- Rename the private parser and update its call site and references.
- Add a type-level test for the deprecated alias.
## Verification
- `npx tsc --noEmit -p packages/adapter-utils`
- `npx vitest run
packages/adapter-utils/src/execution-target-sandbox.test.ts`
- `npx vitest run
server/src/__tests__/environment-execution-target-capabilities.test.ts
server/src/__tests__/environment-execution-target-duplex.test.ts`
- The local checks passed with 133 adapter-utils tests and 31 server
tests.
- Reviewers can confirm that the runtime field and capability flags stay
unchanged.
## Risks
Low risk. The alias protects existing type imports. The change does not
alter runtime behavior or serialized data.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution. The runtime does not
expose the context window size.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip records first-party events, OpenTelemetry data, and local
run-log events
> - The code and documents used one term for these three data paths
> - This naming made the required review level unclear
> - This pull request names each data path in the module names,
documents, and code comments
> - The benefit is a clear review rule without a runtime change
## Linked Issues or Issue Description
**Issue type**
Unclear or confusing.
**Where is the issue?**
`packages/shared/src/telemetry/README.md`, `doc/observability.md`,
`doc/run-log-events.md`, and the duplex instrumentation modules.
**What's wrong?**
The repository used Telemetry for first-party events, OpenTelemetry
data, and local run-log events. This usage made the data path and review
level unclear.
**Suggested fix**
Use Telemetry only for Paperclip first-party events. Use Observability
for OpenTelemetry data. Use the run log for rows in
`heartbeat_run_events`.
Related public pull requests: #8476 and #9672.
## What Changed
- Rename the duplex instrumentation modules and identifiers from
`Telemetry` to `Observability`.
- Move the Observability and run-log contracts out of the Telemetry
README.
- Add `doc/observability.md` and `doc/run-log-events.md` as the
canonical documents.
- Add a file-path review rule to `AGENTS.md`.
- Correct the remaining code comments that name the wrong data path.
- Keep all event names, payloads, database records, spans, configuration
keys, environment variables, and runtime paths unchanged.
## Verification
- `npx vitest run packages/shared/src/telemetry/readme-contract.test.ts`
passes.
- `npx vitest run packages/adapter-utils/src/published-exports.test.ts`
passes.
- `npx vitest run
packages/adapter-utils/src/acpx-engine/startup-timing.test.ts` passes
with 42 tests.
- `pnpm --filter @paperclipai/adapter-utils typecheck` passes.
- `pnpm --filter server typecheck` passes.
- The old module name does not remain in TypeScript or JSON files,
except for the intentional publication guard.
- CI and Greptile checks remain pending after PR creation.
## Risks
- The old duplex module subpath no longer has a compatibility shim. The
board accepted this intentional hard break.
- The new duplex module subpath stays blocked from package publication.
- The change has no runtime effect. The main risk is an incorrect
document or module reference.
## Model Used
OpenAI GPT-5 Codex, exact model ID `gpt-5`, with tool use and code
review support.

## Thinking Path

> - The benefit is that a gateway fault degrades one request instead of
severing the agent from the control plane until run end
## Linked Issues or Issue Description
Refs #12052 (host-side worker half of the same relay). Refs #9904 and
#8977 (adjacent bridge behavior).
No public issue exists for this defect. The description below follows
the bug report template.
**What happened?**
During a staging run, an agent's API calls to the bridge's loopback port
began failing at the connection level (curl reported HTTP 000) partway
through the run. A dead gateway process is the only mechanism that
produces connection-level failures on that port, and nothing restarts
it. Separately, request files for timed-out requests stayed in the
queue; after 64 accumulated, the gateway answered every request with
`503 Bridge request queue is full.` until the run ended.
**Expected behavior**
An uncaught fault in the gateway must not kill the loopback listener. A
request that times out must not leave its file counting toward the
queue-depth cap. A queue full of orphaned files must recover instead of
rejecting until run end.
**Steps to reproduce**
1. Start a remote-sandbox run and stop the host-side bridge worker.
2. Send requests to the gateway until they time out; the request files
stay in `requests/`.
3. After 64 such files, every request gets an immediate 503, even after
the host recovers.
4. Independently, raise any uncaught exception in the gateway process;
the loopback port dies for the rest of the run.
## What Changed
- The generated gateway source installs global `uncaughtException` /
`unhandledRejection` handlers that log to stderr (already redirected to
`logs/bridge.log`) and keep serving. The relay holds no state a fault
can corrupt beyond the one request it interrupted.
- Survival is gated on readiness: before the gateway has written its
readiness file (file mode) or sent its READY frame (duplex mode), the
same handlers exit(1) instead. A startup fault (failed bind, failed
readiness write) means the process can never serve, and surviving there
would only leave an un-ready zombie while the host waits out its
readiness poll.
- The file gateway attaches an explicit `error` listener to its server
and pins the event loop with a keepalive until the bind settles. Newer
Node runtimes do not reliably surface a failed bind through
`uncaughtException` in this shape: the process can drain and exit 0
before the error event is delivered (reproduced on Node 24/25; Node 22
delivered it). The duplex gateway already had an explicit listener.
- A request that times out waiting for the host now deletes its own
request file. The host's response write is guarded on that file, so the
removal also signals that no caller waits anymore.
- At the queue-depth cap, the gateway sweeps request files older than
the response deadline (orphans from killed callers or a previous gateway
process) before rejecting with 503.
- Host-side, `processRequestFile` treats a request file that vanished
before the read as the benign caller-gave-up race and skips it quietly
instead of escalating into the recovery pass.
## Verification
- `npx vitest run
packages/adapter-utils/src/sandbox-callback-bridge.test.ts` — 43 passed,
verified on both Node 22 and Node 25.
- New end-to-end test: with no worker running, a request times out
(502), its file is cleaned, and the same gateway then serves a 200 once
a worker starts — no wedge, no dead port.
- New end-to-end test: with `maxQueueDepth: 1` and a backdated orphan
file at the cap, the gateway sweeps the orphan and admits the request
instead of answering 503.
- New worker test: a request file that vanishes before the read is
skipped without a handler call, a response write, or a run-level error.
- New generated-source test: spawned directly against an
already-occupied port, the gateway exits 1 promptly with the
`EADDRINUSE` fault on stderr instead of lingering un-ready (or exiting 0
silently, the pre-existing behavior on Node 24/25).
- A pin keeps the crash handlers, the readiness gate, and the sweep in
the generated source.
- `pnpm --filter @paperclipai/adapter-utils typecheck`.
## Risks
- Keeping a Node process alive after `uncaughtException` is normally
suspect; here the alternative is a dead loopback port for the rest of
the run, and the gateway is a stateless per-request relay. The fault is
logged with its stack to `bridge.log`, and survival applies only after
readiness — startup faults still fail fast.
- Deleting a timed-out request file could race a host that is
mid-processing. The host's response write is already guarded on
request-file existence, and the new host-side skip treats the vanished
file as a no-op, so no duplicate mutation path is introduced.
- The stale sweep runs only at the depth cap and only removes files
older than the response deadline plus a 2 s grace, so a live caller's
file is never swept.
- Orphaned response files (host responded after the caller gave up)
still linger; that pre-existing minor leak is unchanged here.

## Thinking Path

work
> - Adapters inject prompt text that teaches agents how to call the
Paperclip API, including copy-pasteable curl examples
> - Some of those URLs contained brace placeholders like
`/api/issues/{id}/checkout`
> - Agents paste such lines verbatim; the placeholder reaches the server
as `/api/issues/%7Bid%7D` and 404s, and request logs show agents doing
exactly that
> - The acpx engine's API note already avoids this by using
`$PAPERCLIP_TASK_ID`, and its test pins `/api/issues/{id}` out of the
prompt
> - This pull request applies the same standard to the gemini adapter,
the shared prompt template, and the openclaw gateway workflow
> - The benefit is that agents stop burning turns on placeholder 404s
and doc examples stay safe to execute as written
## Linked Issues or Issue Description
No public issue exists for this defect. The description below follows
the bug report template.
**What happened?**
Server request logs show agents issuing `GET /api/issues/%7Bid%7D` — the
literal, percent-encoded text `{id}` — which 404s. The source is adapter
prompt text: the gemini adapter's API note embeds a curl example with
`/api/issues/{id}/checkout` in the URL, the shared agent prompt template
mentions `/api/issues/{issueId}` endpoints, and the harness checkout
notice names `/api/issues/{id}/checkout`. Models copy these strings into
real requests.
**Expected behavior**
URL paths in prompt text must carry environment variables or real ids,
never brace placeholders, in every string an agent might execute
verbatim. Where a placeholder is unavoidable, the prompt must state
explicitly that the literal text must never be sent.
**Steps to reproduce**
1. Give an agent the gemini adapter's API access note.
2. Watch it call `curl ...
"$PAPERCLIP_API_URL/api/issues/{id}/checkout"` as written.
3. The server logs `POST /api/issues/%7Bid%7D/checkout 404`.
## What Changed
- gemini-local's API note curl example now uses `$PAPERCLIP_TASK_ID` and
tells the agent to substitute a real issue id when that variable is
absent — the same convention as the acpx engine's API note.
- The shared agent prompt template (`server-utils.ts`) uses
`$PAPERCLIP_TASK_ID` in its interaction-creation and resume-endpoint
mentions, and the harness checkout notice names `POST
/api/issues/$PAPERCLIP_TASK_ID/checkout`.
- openclaw-gateway's endpoint workflow keeps its `{issueId}`
placeholders — they are defined by its "determine issueId" step — but
now states explicitly that the literal text must never be sent in a URL.
- `server-utils.test.ts` pins the new form and adds negative pins that
keep `/api/issues/{id}` and `/api/issues/{issueId}` out of the shared
prompt template, mirroring the existing acpx-engine negative pin.
- The `confirmation:{issueId}:plan:{revisionId}` idempotency-key
template is untouched: it is a value-construction pattern, not a URL.
## Verification
- `npx vitest run packages/adapter-utils/src/server-utils.test.ts
packages/adapters/gemini-local packages/adapters/openclaw-gateway` — 152
passed. The single failure (`pre-selects gemini-api-key auth in the
managed HOME for sandbox execution`) is a pre-existing
environment-specific failure on the development machine, unrelated to
prompt text; CI is authoritative for it.
- `pnpm --filter @paperclipai/adapter-utils --filter
@paperclipai/adapter-gemini-local --filter
@paperclipai/adapter-openclaw-gateway typecheck`.
## Risks
- Low risk: prompt-text and test changes only; no runtime logic changes.
- Agents that memorized the old example strings keep working — the
routes are unchanged, only the placeholder text in prompts is.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents on remote sandbox targets reach the Paperclip API through the
sandbox callback bridge: a loopback gateway inside the sandbox writes
request files, and a host-side worker polls them over the provider's

slow exec ended the relay for the rest of the run
> - The in-sandbox gateway kept queueing requests against the dead
worker, so every later API call from the agent stranded, including its

hiccup into a lost issue disposition

the control plane mid-run
## Linked Issues or Issue Description
Refs #9904. Refs #8977. Both touch adjacent bridge behavior (curl shim,
header forwarding); neither addresses worker-loop lifetime.
No public issue exists for this defect. The description below follows
the bug report template.
**What happened?**
During a staging run, the host-side bridge worker hit one failed sandbox
exec while relaying requests. The poll loop's only catch is terminal: it
failed the pending requests and set the worker to settled, with no
restart. The agent's later API calls saw connection-level failures or
bridge errors until the run ended. Its final `PATCH status: done` was
lost, and the missing-disposition recovery had to repair the issue in a
corrective run.
**Expected behavior**
One transient exec failure must not end the relay for the rest of the
run. The worker must back off and retry. A sustained outage must still
fail queued requests fast through the watchdog. In-flight request
semantics (abort plus 504 backstop, retry-safe 503) must not change.
**Steps to reproduce**
1. Start a remote-sandbox run and let the provider exec channel reject
or stall one call while the bridge worker polls.
2. The worker hits one `listJsonFiles` failure or one request-attempt
timeout, and the loop exits through its terminal catch.
3. Every later bridge request strands. The loopback gateway keeps
accepting requests that never complete, and after 64 queued files it
answers every request with 503 until run end.
## What Changed
- `startSandboxCallbackBridgeWorker`'s poll loop now separates three
failure domains:
- A failed poll backs off exponentially (capped at 5 s) and retries
instead of dying. The first failure of a streak still lands on the run
trace through the workerFailed span; later repeats only warn.
- A failed or hung request attempt runs the same recovery pass the loop
previously died on — abort the in-flight handler (its 504 backstop keeps
the caller from stranding) and 503 the unclaimed queued requests — and
the loop then continues and serves the caller's retry.
- A listing where every file already has an in-flight attempt sleeps one
poll interval, like an empty listing. The previous immediate re-list was
a hot spin: an exec storm against a real channel, and a pure-microtask
loop that starved every timer in the process when the queue client
resolves synchronously.
- The watchdog, the claim/finalize fences, and the stop/drain semantics
are unchanged.
## Verification
- `npx vitest run
packages/adapter-utils/src/sandbox-callback-bridge.test.ts` — 38 passed.
- New regression test: a request queued behind three consecutive poll
failures is still delivered.
- Updated tests: the stalled-poll test now expects recovery (the
handler's real 200) instead of a terminal 503; the sustained-outage 503
path remains proven by the dedicated watchdog test; the
recovery-503-write-retry test triggers the recovery pass through a hung
request read, because a hung poll no longer runs that pass.
- `pnpm --filter @paperclipai/adapter-utils typecheck`.
## Risks
- Behavior change: a transiently failing poll no longer mass-fails
queued requests on the first error. Callers wait through the backoff
window, bounded by the existing in-sandbox 30 s response deadline, or
the watchdog fails them after 20 s of no successful iteration. This
trades fast-but-terminal degradation for recovery.
- A hard-down channel now retries every ≤5 s for the rest of the run
instead of stopping. Each retry is one exec attempt against a channel
that already fails.
- In-flight mutation safety is unchanged: the guard map and the claim
protocol still prevent a double-applied host mutation, and a guarded
file is always finalized by its own attempt or by its 504 backstop.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters use provider-specific login flows
> - Codex device login needs a live pseudo-terminal (PTY), while the
shared channel still uses Claude-specific names
> - The old streamed-exec path does not provide the prompt transport
that Codex needs
> - This pull request moves Codex device login to the shared login PTY
and removes the dead streamed-exec path
> - The benefit is one controlled login transport with fail-closed
capability checks and safer credential reads
## Linked Issues or Issue Description
**Problem or motivation**
Codex device login used a streamed-exec path that did not provide the
required prompt transport. The shared login channel also exposed
Claude-specific names outside Claude code.
**Expected behavior**
The host selects a fixed login command from trusted adapter data. Codex
login uses the provider login PTY. Providers without that capability
fail closed.
**Proposed solution**
Use a server-controlled session home, create and validate it as a fresh
0700 directory, read credentials from one validated descriptor, and
rename shared channel names to the neutral login PTY family.
**Alternatives considered**
Keep the shared login PTY as the single transport. Do not keep the
removed streamed-exec path because it cannot provide the required prompt
transport.
**Roadmap alignment**
This change supports the planned login transport work. It does not add a
separate roadmap item.
## What Changed
- Route Codex device login through the shared login PTY transport.
- Select the login command from a closed internal command key.
- Carry a server-controlled session home through the launch contract.
- Create and validate the session home as a fresh 0700 directory owned
by the login user.
- Read the credential file with descriptor-relative, no-follow path
walking and final descriptor checks.
- Gate the login route and run lease on the provider login PTY
capability.
- Rename shared channel names to the neutral login PTY family.
- Remove the streamed-exec transport value, selector field, driver
branch, and related tests.
- Hide Codex login in the user interface when the provider lacks the
login PTY capability.
## Verification
- Server unit suites pass: 89/89.
- Adapter-utils suites pass: 262/262.
- Codex-local suites pass: 326/326.
- Credential-read reader suite passes: 20/20.
- Daytona login PTY suite passes: 30/30.
- Device-login suites pass: 56/56.
- TypeScript checks pass for server, adapter-utils, and UI.
- GitHub Actions must pass after pull request creation.
- Greptile review must reach 5/5 with no open P2 findings,
recommendations, or follow-ups.
## Risks
- Providers without a login PTY capability lose Codex login support by
design.
- The credential read rejects invalid ownership, mode, type, path, and
size.
- The launch-time sandbox directory race remains outside the threat
model because the login runs inside the sandbox and a hostile sandbox
already controls its credential.
## Model Used
OpenAI Codex, GPT-5, tool use and code review assistance. The exact
context window and reasoning mode are not exposed by the runtime.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent adapters use a duplex bridge to send requests and responses
across an isolated boundary
> - The bridge held each request body and response body in memory on
both ends
> - Large bodies can exhaust memory and reduce the safe size of adapter
traffic
> - This pull request sends receive-side bodies as sequenced chunks and
spills large bodies to disk
> - The benefit is bounded memory use with strict size, order, and
cleanup checks
## Linked Issues or Issue Description
**What existing behavior does this improve?**
The adapter-utils duplex bridge transports request and response bodies
across the sandbox boundary.
**Current behavior**
The bridge stores each complete body in memory on both ends of the
duplex channel.
**Proposed behavior**
The bridge sends body chunks with sequence checks. The receive side
keeps bodies up to 1 MiB in memory and spills larger bodies to a
temporary file.
**Reason and benefit**
This change reduces memory pressure and keeps malformed or oversized
input on a terminal error path.
**Breaking changes**
The duplex frame version changes to version 2. The request and response
envelopes now carry bodyByteCount, and body_chunk frames carry the body
data.
## What Changed
- Add version 2 body_chunk frames with 256 KiB raw slices encoded as
canonical base64 text.
- Add receive-side memory and spill reassembly with per-channel disk and
file limits.
- Reject malformed, reordered, oversized, truncated, and non-canonical
body chunks.
- Stream reassembled request bodies to the host forward handler with a
web stream and half-duplex request.
- Remove spill files on success, failure, channel death, and startup
cleanup.
## Verification
- Run the adapter-utils type-check.
- Run the adapter-utils duplex test suite.
- Run all pull request checks.
- Run the Greptile review and confirm a 5/5 score with no open findings.
## Risks
The wire format changes from version 1 to version 2. Older bridge peers
cannot use this protocol. The receive path adds temporary file
operations and cleanup paths. The implementation fails closed when a
body violates size or sequence rules.
## Model Used
OpenAI GPT-5 Codex, tool-enabled coding agent. The exact context-window
size and reasoning mode are not exposed by the runtime.

## Thinking Path
> - Paperclip runs AI agents through adapters and sandboxed execution
targets.
> - Duplex routes retain bytes across route data, broker messages,
decoder buffers, and readiness replay.
> - Per-route limits bound each route but do not bound the total
retained bytes across many routes.
> - A process-owned ledger must charge each retained buffer before
allocation and release the charge during cleanup.
> - This pull request adds the aggregate ledger, connects it to host and
sandbox duplex paths, and adds route coverage.
> - The benefit is a fail-closed process-wide byte limit that keeps
concurrent duplex work within a safe resource budget.
## Linked Issues or Issue Description
**Subsystem affected**
This change affects packages/adapter-utils and server duplex
orchestration.
**Problem or motivation**
Many routes can each stay below their per-route limits while their
combined retained bytes exceed a safe process budget.
**Proposed solution**
Add a process-owned aggregate byte ledger. Charge route data, broker
bytes, decoder buffers, and readiness replay bytes before allocation.
Release each charge during cleanup. Use a separate sandbox_process
decoder cap for the in-sandbox path.
**Alternatives considered**
Keep only per-route limits. This does not bound the combined process
use. Set a fixed limit at one call site. This misses retained bytes in
other duplex paths.
**Roadmap alignment**
This is a tightly scoped reliability and resource-safety improvement. It
does not duplicate a roadmap feature.
**Additional context**
The aggregate ceiling uses a safe 256 MiB default. An invalid override
falls back to that default and reports the rejected value.
## What Changed
- Add a process-owned aggregate byte ledger for duplex route resource
use.
- Charge and release route data, broker forward and response bytes,
decoder buffers, and readiness replay bytes.
- Bound host-to-worker pending writes and standard input transport
bytes.
- Add a separate decoder cap for the sandbox_process path.
- Make invalid aggregate-ceiling overrides fall back to the safe default
without host startup failure.
- Add adapter-utils and server tests for charging, release, rejection,
cleanup, and many-route aggregate limits.
## Verification
- pnpm --filter @paperclipai/adapter-utils exec tsc --noEmit
- pnpm --filter @paperclipai/server exec tsc --noEmit
- Run the focused adapter-utils duplex ledger and execution-target
tests.
- Run the server aggregate-ledger route test.
- Confirm all required pull request checks pass on this branch.
## Risks
The ledger touches several duplex buffer paths. A missed release could
reduce later capacity until process restart. The tests cover charge,
release, rejection, cleanup, and route aggregation. The change uses a
safe default when configuration input is invalid.
## Model Used
OpenAI GPT-5 Codex. The runtime model ID and context window are not
exposed to this task. The model used tool calls, shell commands, and
code review workflow support.

## Thinking Path

## Linked Issues or Issue Description
**What happened?**
The Daytona duplex path sent a full input payload as one WebSocket
message. A payload above the provider limit closed the channel. The wait
path also mapped a non-numeric exit result to a process exit without
exit data.
**Expected behavior**
The provider must receive large input as ordered UTF-8 chunks. A
transport close without exit data must record `transport_closed`, while
a numeric exit must record `provider_exit`.
**Steps to reproduce**
1. Start a Daytona duplex session.
2. Send an input payload larger than 65536 bytes.
3. Observe that one message closes the provider channel.
4. End a session without a numeric exit code.
5. Observe that the loss reason reports a process exit.
**Paperclip version or commit**
Commit `1761e79ec9097c65d94f90a8ba20416f8ab718a6`.
**Deployment mode**
Built from source with the Daytona sandbox provider.
## What Changed
- Add a shared UTF-8 byte chunker with a 32768-byte cap.
- Route both Daytona pseudo-terminal write paths through the chunker.
- Preserve multi-byte UTF-8 sequences across read-side chunks.
- Carry an explicit `transportClosed` state through the worker and host
wait paths.
- Record `transport_closed` for a reason-less transport close and
`provider_exit` for a numeric exit.
- Keep orderly completion suppression for both exit paths.
## Verification
- The Daytona plugin suite passes 194 tests.
- The adapter-utils broker, codec, and telemetry suites pass 73 tests.
- The plugin SDK duplex and worker RPC host suites pass 37 tests.
- The server plugin worker manager duplex suite passes 78 tests.
- The execution target sandbox and ACPX execute suites pass 257 tests.
- TypeScript checks pass for adapter-utils, plugin SDK, server, and the
standalone Daytona plugin.
## Risks
The chunk size adds a loop for large input payloads. The 32768-byte cap
stays below the provider limit. The optional loss field preserves
compatibility for other providers.
## Model Used
OpenAI Codex, GPT-5, extended reasoning, tool use, and code execution.
The runtime does not expose a separate context-window value.

## Thinking Path
> - Paperclip uses adapter utilities to move bounded messages between
agent processes.
> - The duplex frame codec encodes and decodes these messages.
> - The decoder rejects frames above the documented byte limit.
> - The encoder did not apply the same limit before it sent a frame.
> - This mismatch let a sender write a frame that the peer rejected
after transmission.
> - This pull request applies the same byte limit to both codec copies
and keeps the broker channel open.
> - The benefit is a local error with stable request telemetry instead
of a channel loss.
## Linked Issues or Issue Description
No public GitHub issue exists for this change. The problem follows the
bug report fields below.
**What happened?**
The duplex encoder could write a frame larger than
`DEFAULT_MAX_DUPLEX_FRAME_BYTES`. The peer decoder then rejected the
frame after transmission. In the WebSocket 1009 case, this closed the
channel and reported a process exit.
**Expected behavior**
The encoder should reject an oversized frame before it writes bytes. The
gateway should return HTTP 413. The broker should return a bounded
terminal response and keep other requests active.
**Steps to reproduce**
1. Encode a duplex frame above `DEFAULT_MAX_DUPLEX_FRAME_BYTES`.
2. Send the frame through the gateway or broker.
3. Observe that the old path writes the frame or drops the channel after
peer rejection.
**Paperclip version or commit**
Reproduced from the `master` development line before this change.
**Deployment mode**
Local dev (`pnpm dev`).
## What Changed
- Add `encodeDuplexFrameChecked` to the host and embedded gateway
codecs.
- Measure encoded JSON bytes without the trailing newline.
- Return a typed `frame_too_large` result without throwing.
- Return HTTP 413 for oversized gateway requests without writing a
frame.
- Share one frame bound between broker decode and encode checks.
- Return a bounded, non-retryable terminal response for oversized broker
responses.
- Add encode vectors to the shared wire-compatibility fixture.
## Verification
- Run `pnpm --filter @paperclipai/adapter-utils typecheck`.
- Run `npx vitest run
packages/adapter-utils/src/duplex-frame-codec.test.ts
packages/adapter-utils/src/duplex-bridge-broker.test.ts
packages/adapter-utils/src/execution-target-sandbox.test.ts`.
- Confirm the oversized-response broker test keeps the channel open and
serves the other in-flight request.
- Confirm the gateway test returns HTTP 413 and keeps the channel open.
## Risks
The encoder now rejects oversized frames before transmission. This
changes an unsafe write into a typed local error. The broker and gateway
keep existing frame limits and affect only oversized frames.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution. The model assisted
with review and repository operations.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip runs agents through adapter execution lanes
> - Duplex adapters can lose their control channel before a process
completes
> - The ACP lane already fails closed, but the CLI lane can report false
success
> - This pull request applies the same completion rule to the CLI lane
and shares the loss code
> - The benefit is consistent failure reporting when a duplex channel
closes during a run
## Linked Issues or Issue Description
**What happened?**
A CLI-lane duplex run can lose its control channel before clean process
completion. The run can then report `succeeded` with exit code 0 and no
error code.
**Expected behavior**
The execution target must fail closed when the channel dies before clean
completion. It must return exit code 1, the typed `duplex_channel_lost`
error code, and a short stderr note.
**Steps to reproduce**
1. Start a duplex adapter run through the CLI execution lane.
2. Close the duplex control channel before the process completes
cleanly.
3. Inspect the run result and error code.
**Paperclip version or commit**
Commit `5e01523d4eb6df4a20a0bddd05374c9c42225203`.
**Deployment mode**
Built from source.
**Installation method**
Built from source with pnpm.
**Agent adapter(s) involved**
Claude Code, Codex, Cursor, Gemini, Kimi, OpenCode, and Pi local
adapters.
**Database mode**
Not database-related.
## What Changed
- Add an optional `errorCode` field to `RunProcessResult`.
- Add a one-read completion seam to the execution target process
options.
- Fail closed when a duplex channel dies before clean process
completion.
- Add `settleRunDisposition()` to atomically read and mark orderly
completion.
- Share the typed duplex loss error code across the ACP and CLI lanes.
- Mark non-success terminal results as orderly completion before
teardown.
- Wire the seam through the seven duplex adapters.
- Add regression tests for channel loss, clean completion, and non-clean
terminal results.
## Verification
- `npx vitest run
packages/adapter-utils/src/execution-target-sandbox.test.ts` — 118
passed.
- `npx vitest run packages/adapter-utils/src/acpx-engine/execute.test.ts
-t "sandbox duplex run-disposition seam"` — 4 passed.
- The author confirmed a clean type-check for
`@paperclipai/adapter-utils` and the seven duplex adapter packages.
- Pre-existing environment failures remain outside this change. They
include `EACCES mkdir '/srv/paperclip'` and remote file-size setup
failures.
## Risks
The change alters terminal status for CLI duplex runs that lose control
before clean completion. The typed error code and stderr note keep the
failure visible. The broker marks failed, cancelled, and timed-out
results as orderly completion to prevent false loss events during
teardown.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution, with the standard
GPT-5 context window. The model assisted with the implementation and
test work.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Sandbox adapters provide controlled execution for untrusted provider
environments.
> - The sandbox channel needs one persistent duplex transport with
strict host control.
> - The transport must remain off unless the instance setting and
provider capability both allow it.
> - The host must detect loss, bound resource use, and expose only safe
telemetry.
> - This pull request adds the broker, gated selection, kill-switch
wiring, fixed observability, and real-process proof.
> - The benefit is safer sandbox execution with bounded failure behavior
and inspectable transport results.
## Linked Issues or Issue Description
No public issue exists for this change. The related pull requests are
#11738 and #11750.
**Problem or motivation**
The sandbox duplex channel needs a host-controlled broker, strict
transport gates, bounded provider input, and safe loss telemetry.
Without these controls, a provider can cause replay, resource growth,
unsafe endpoint selection, or data exposure through telemetry.
**Proposed solution**
Add a host broker with nested time limits, request limits, one-shot
loss, and per-id deduplication. Select duplex transport only when the
instance setting and provider capability both equal true. Assign the
endpoint and nonce on the host. Reject invalid readiness data and use
the file bridge on failure. Add fixed redacted telemetry and a
real-process end-to-end test harness.
**Alternatives considered**
Keep the file bridge as the only transport. This avoids new channel
behavior but does not provide persistent duplex operation for supported
sandbox providers.
**Roadmap alignment**
This change supports the Cloud / Sandbox agents section in ROADMAP.md.
## What Changed
- Add the duplex bridge broker with bounded forward, response, and
gateway wait budgets.
- Bound concurrent requests, lifetime requests, and request-id bytes
before retention or forwarding.
- Select duplex transport only when both required gates are true.
- Assign the loopback port and nonce on the host and enforce a
liveness-only READY frame.
- Fall back to the file bridge after invalid readiness, contamination,
bind failure, or timeout.
- Carry the kill switch through the server, acpx engine, and six local
adapters.
- Add fixed, redacted duplex telemetry with a provider allowlist.
- Add a real-process end-to-end harness for readiness, round trips,
loss, and teardown.
- Add regression coverage for limits, loss, UTF-8 splits, concurrency,
and telemetry dimensions.
## Verification
- Adapter-utils, server, and Daytona typechecks pass locally.
- Adapter-utils tests pass, including the codec, broker,
execution-target sandbox, and real-process harness.
- Server kill-switch tests pass.
- Live Daytona tests pass with the required provider key and skip
without that key.
- The root pnpm-lock.yaml file has no diff.
- The branch contains ten commits after origin/master.
## Risks
- Duplex transport remains disabled unless both gates equal true.
- A provider remains an untrusted boundary and needs least-privilege
credentials and quotas.
- The server telemetry recorder stays deferred; the default recorder
does nothing.
- A provider that pre-binds the host port causes a fail-closed fallback
to the file bridge.
- The change adds no database migration and changes no root lockfile.
## Model Used
OpenAI GPT-5, exact model family GPT-5, large context window, reasoning,
and tool use. The model assisted with Git handoff validation and PR
preparation. The implementation commits came from the engineering
worktree.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Managed deployments provision a platform-managed default environment
for agent runs; the UI shows this environment in selectors, the agent
form, run details, and the environments page
> - Those surfaces append the raw driver key to the environment name, so
users see labels like "Paperclip Computer (sandbox)", "Paperclip
Computer · sandbox", and fallback copy such as "Managed sandbox" and
"The sandbox has no ready authentication"
> - "sandbox" is infrastructure vocabulary, not the product name of the
environment; showing it next to the managed environment's name is
confusing and off-brand
> - This pull request renders platform-managed environments by name
alone and rewords the sandbox-phrased copy, while user-created
environments keep the driver suffix so mixed lists stay distinguishable
> - The benefit is that the default environment reads as one clear
product name everywhere, and self-hosted users lose nothing: their own
environments still show the driver
## Linked Issues or Issue Description
**What existing behavior does this improve?**
Display of the platform-managed default environment across the UI.
**Subsystem affected**
UI (environment selectors, agent config form, environments page, agents
page, run details) and the claude-local/codex-local adapter auth checks.
**Current behavior**
The agent form labels the inherited default environment as "Name
(sandbox)". Environment selectors and the environments list render "Name
· sandbox". The agents page describes the environment as "<provider>
sandbox provider". The agent form's fallback label is "Managed sandbox".
Adapter auth checks say "The sandbox has no ready authentication for
this adapter."
**Proposed behavior**
Platform-managed environment rows (`metadata.managedByPaperclip`) render
their name alone. The fallback label is "Paperclip Computer". The agents
page describes managed environments as "Managed by Paperclip". Run
details omit the driver suffix for sandbox-driver environments (the
adjacent Provider entry already identifies the mechanism). Adapter auth
checks say "This environment has no ready authentication for this
adapter."
**Reason and benefit**
The managed environment carries a product name. Appending the raw driver
key ("sandbox") to it is noise and contradicts the product naming.
User-created environments keep the driver suffix, so mixed lists stay
distinguishable.
**Breaking changes**
None. Message text of the auth check is not read programmatically; the
UI keys off `ADAPTER_AUTH_MISSING_CHECK_CODE`. Rows without the managed
marker render exactly as before.
## What Changed
- New `environmentDisplayLabel` helper in
`ui/src/lib/managed-sandbox-environment.ts`: managed rows → name alone;
other rows → "Name · driver".
- `AgentConfigForm`: inherited-default label uses the helper; fallback
copy "Managed sandbox" → "Paperclip Computer"; environment options use
the helper.
- `ProjectProperties`, `CompanyEnvironments`: environment selector
options use the helper; the environments-list row hides the driver
suffix on managed rows; the managed detail page's fallback description
no longer says "sandbox".
- `Agents` page: managed environments are described as "Managed by
Paperclip" instead of "<provider> sandbox provider".
- `CommentThread` run details: the driver suffix is omitted for
sandbox-driver environments.
- claude-local and codex-local adapters: auth-missing check message/hint
reworded from "sandbox" to "environment" (ACP and environment-test
paths); claude-local probe/effort/login hints reworded the same way.
- Run status lines: "Syncing workspace to sandbox", "Exporting git
changes from sandbox", "Starting adapter in sandbox", and friends now
say "environment"; "Finalizing sandbox workspace" → "Finalizing
workspace". Templated transfer-progress lines map the `sandbox`
transport key to "environment" for display (`runtime-progress.ts`).
- Agent form sign-in panel: "Sign in to the sandbox" → "Sign in to the
environment"; "Authenticated. The sandbox has credentials now." → "…The
environment has credentials now."
- Feature catalog + instance settings card: "Managed Sandbox Only" →
"Managed Environment Only" (setting key unchanged; the card keeps its
alphabetical slot).
- Server agents routes: execution-target failure and test-identity copy
no longer say "sandbox"; workspace-mode label "Cloud sandbox" → "Cloud
environment".
- Tests: new `environmentDisplayLabel` unit cases; new `AgentConfigForm`
render case asserting the managed default renders without "(sandbox)" or
"· sandbox"; status-line assertions updated across adapter-utils, server
heartbeat/live-run, and UI chat suites.
## Verification
- `pnpm --filter @paperclipai/ui typecheck` — clean.
- `pnpm --filter @paperclipai/adapter-claude-local typecheck` and
`--filter @paperclipai/adapter-codex-local typecheck` — clean.
- `vitest run` for `managed-sandbox-environment.test.ts`,
`AgentConfigForm.render.test.tsx`, `CompanyEnvironments.test.tsx`,
`Agents.test.tsx`, `CommentThread.test.tsx`, `NewAgent.test.tsx` — all
green (118 tests across the two runs).
## Risks
Low risk. Cosmetic label changes only; no data or API changes. Rows
without `metadata.managedByPaperclip` render exactly as before, so
self-hosted deployments with their own environments see no change. The
only self-hosted-visible wording changes are the adapter auth-check
message and the driver suffix omission on sandbox-driver rows in run
details.

## What Changed
- Require Node.js 24.11.0 or newer in all 42 package manifests and
runtime checks.
- Use Node.js 24 in GitHub Actions, Docker images, smoke images, sandbox
setup, portable installs, and esbuild targets.
- Align every direct `@types/node` declaration on `^24.0.0`.
- Prevent Dependabot from opening major `@types/node` upgrades without a
matching runtime decision.
- Add `.nvmrc` and a CI policy check for Node version drift.
- Update ACP version gates, tests, and user documentation for the new
minimum.
- Print a non-blocking warning on CLI and server startup when Node is
unsupported, with remediation through a version manager or the
documented downloaded `install.sh` workflow.
- Deduplicate that warning when `paperclipai run` boots the CLI and
server in the same process.
## Verification
- `node scripts/check-node-version-policy.mjs`
- `node --check scripts/check-node-version-policy.mjs`
- `node --check cli/esbuild.config.mjs`
- `node --check scripts/generate-npm-package-json.mjs`
- `bash -n scripts/install.sh scripts/test-install-sh-docker.sh
scripts/e2e-install-lifecycle.sh`
- Parsed all 42 package manifests and confirmed `engines.node` is
`>=24.11.0`.
- `git diff --check`
- `vitest run
packages/adapter-utils/src/sandbox-install-command.test.ts` passed with
3 tests.
- `vitest run cli/src/node-version.test.ts` passed with 4 tests.
- Directly exercised the shared warning helper for unsupported-version
messaging and same-process deduplication.
- The focused exe.dev suite could not resolve the locally unbuilt plugin
SDK from this isolated worktree. A full offline workspace install was
also blocked because the package-manager signature verifier requires
registry access. The full suite was not run locally; draft CI performs a
clean install and evaluates the wider impact.
## Risks
- This is a breaking runtime change for users, plugins, and deployments
that still use Node.js 20 or 22.
- Published workspace packages will now produce an engine warning or
failure in strict package managers on older Node.js releases.
- Node.js 24 can reveal dependency, native module, Playwright, or agent
CLI compatibility issues in CI.
- The bootstrap installer now installs Node.js 24 when the current
runtime is older than 24.11.0.
- The portable sandbox fallback is pinned to Node.js 24.11.0 and depends
on that upstream tarball remaining available.
- Unsupported runtimes continue booting after a warning, so a later
incompatibility can still fail at its point of use.
- The CLI and server share the warning policy through the published
`@paperclipai/shared` package; packaging checks must keep that subpath
export available.
- This PR does not commit `pnpm-lock.yaml` because repository policy
assigns lockfile generation to CI.

## Thinking Path

**What happened?**
The ACPX engine used the full summary strategy when an adapter did not
set `summaryStrategy`. That strategy joined all text deltas, including
thought-stream text and intermediate narration. The heartbeat finalizer
could then store that summary as an issue comment.
**Expected behavior**
An automatic issue comment must use only the final output segment.
Configuration must not allow thought-stream text or intermediate
narration into that summary.
**Steps to reproduce**
1. Run an ACPX adapter without a configured `summaryStrategy`.
2. Emit an output delta, a thought delta, a tool call, and a final
output delta.
3. Read the generated run summary.
4. Observe that the old default included all text deltas.
**Paperclip version or commit**
`54b8bec44417511c623999613f9f1006f8af0517`
**Deployment mode**
Built from source with a local ACPX adapter.
## What Changed
- Limit ACPX run summaries to the final non-empty output segment.
- Ignore the legacy full-summary setting so configuration cannot bypass
containment.
- Update regression tests for the safe default and an attempted unsafe
override.
## Verification
- Observed the new guard fail before the implementation change because
the summary contained thought text.
- Ran `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts -t "defaults run
summaries to the final output segment without thought text|does not
allow configuration to include thought text in run summaries"`. Result:
2 passed.
- Ran `pnpm exec vitest run
packages/adapter-utils/src/acpx-engine/execute.test.ts`. Result: 130
passed.
- Ran `pnpm --filter @paperclipai/adapter-utils typecheck`. Result:
passed.
## Risks
- Run summaries are shorter for adapters that relied on full text
aggregation.
- The old `summaryStrategy: "full"` setting no longer changes summary
behavior. This is an intentional containment change.
- The change does not alter run logs or tool events. It changes only the
summary selected for downstream use.
> This is a focused security and privacy bug fix. It does not add
roadmap scope.
## Model Used
- OpenAI Codex on the GPT-5 family. The runtime did not expose the exact
model ID or context-window size. Reasoning, tool use, terminal
execution, and code editing were enabled.
