Refs: #12931
**What happened?**
The full direct live eval campaign failed every ACPX cell during
`session.open`. The portable runtime had an incorrect dependency root.
Its npm install also discarded the qualified ACP server patches.
AgentCore cells first failed because Runner enforced
`aws-agentcore-harness-v1` while the provisioned stack and eval profile
use `aws-agentcore-harness-context-v2`; after aligning that revision,
the direct eval CLI still omitted the required v3 runtime context.
**Expected behavior**
The direct eval runtime must preserve the frozen pnpm dependency graph
and patched provider bytes. Runner, server validation, OpenAPI, and the
deployed AgentCore stack must use one qualification revision. Direct
eval attempts must supply the same immutable native runtime-context
contract as production.
**Steps to reproduce**
1. Dispatch `Runner Direct Live Protocol Evals` from `master`.
2. Select an ACPX Claude, ACPX Codex, or AgentCore roster.
3. Observe a pre-turn provider bootstrap failure.
**Paperclip version or commit**
`d96452db059338b329b458ba8fe359fef72f1363`
**Deployment mode**
GitHub Actions on the RunsOn Linux x64 fleet.
## What Changed
- Build the reusable direct-eval runtime with `pnpm deploy --prod`.
- Resolve ACPX dependencies from the actual scoped-package layout of a
self-contained pnpm deployment.
- Align AgentCore configuration and qualification checks on
`aws-agentcore-harness-context-v2`.
- Materialize a minimal immutable v3 runtime context for each isolated
direct eval attempt.
- Add workflow, package-authority, runtime-context, Rust, and server
regression coverage.
- Document the qualified packaging, runtime-context, and AgentCore
revision contracts.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner typecheck`
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/paperclip-runner exec vitest run
src/live/runnerd-codex-transport.test.ts` (70 tests)
- `pnpm --filter @paperclipai/paperclip-runner exec vitest run
src/cli/eval-session-contract.test.ts` (14 tests)
- Focused Runner contract tests (36 tests)
- Focused server profile tests (47 tests)
- Focused Rust managed-provider and native-selector tests (19 tests)
- `node --test
packages/paperclip-runner/scripts/runner-protocol-eval-workflow-security.test.mjs`
- `actionlint .github/workflows/runner-protocol-live-evals.yml`
- A local `pnpm deploy --prod` produced both qualified ACP server
digests.
- A Linux reproduction of the first follow-up smoke identified the real
deployment root and the missing AgentCore runtime context.
## Risks
The AgentCore revision change rejects profiles that still use the
obsolete v1 value. This is intentional because the provisioned
context-aware harness and current eval profile use v2. Direct eval
prompts now receive the same fixed runtime-context preamble as
production, so behavior scores may move; that is the intended
qualification surface. The workflow package layout changes, but tests
assert the new entrypoint and dependency root. This change does not
modify the browser full-stack E2E workflow.

## Linked Issues or Issue Description
Refs #12845
Related search results: #12646 covers indeterminate command results
after a runner restart. It does not cover controller adoption or
active-turn rebinding. No open duplicate pull request was found.
## What Changed
- Store lazy runnerd process ownership after provider session creation,
read, and resume.
- Detach native PRP controller authority during coordinated hot
shutdown. Keep the live provider turn running.
- Restore the exact checkpointed provider session when bounded PRP
identity events have been compacted.
- Restore the active provider turn before reconnect events are replayed.
This prevents `turn_binding_mismatch`.
- Keep exact live ownership by the current controller out of generic
orphan recovery.
- Add driver, transport, and server regression tests for these paths.
## Verification
- Ran 12 Codex driver lifecycle tests.
- Ran 53 runnerd transport tests.
- Ran 143 recovery and orphan-reaper server tests.
- Ran all 8 real-process restart recovery scenarios.
- Ran all 96 existing runner E2E unit tests.
- Ran runner TypeScript typecheck.
- Ran server TypeScript typecheck.
- Ran the migration replay test and migration safety checks.
- Tested the board UI on an isolated local instance. A real local
Codex-backed turn entered a 120-second terminal wait. The UI `Restart
now` action replaced the server and kept the same runner PID, process
start time, run ID, native session ID, runner ID, provider session ID,
and active turn. The original turn then completed.
- Confirmed one heartbeat run, no retry row, one result, one
proposed-result event, one terminal event, no protocol errors, no active
recovery state, and no surviving runner or provider process.
## Risks
- A live runner can continue provider work while no server owns the
control route. Recovery fails closed when the process fingerprint or
durable identity is ambiguous.
- Provider identity can be restored from the database only for an exact
verified adoption claim. An authenticated live `session.snapshot`
validates that identity before the driver can resume.
- The new detach path applies only to native sessions that expose
restart detachment. Other adapters keep their existing shutdown
behavior.
- This follow-up does not change the database migration or
`package.json`. The migration in #12845 remains replay-safe through `ADD
COLUMN IF NOT EXISTS` and its embedded-Postgres idempotence test. The
dedicated real-process command remains in `doc/DEVELOPING.md`.
## Model Used
- OpenAI Codex based on GPT-5. The exact serving build and
context-window size are not exposed. The run used extended reasoning,
repository tools, shell execution, and in-app browser automation.

## Linked Issues or Issue Description
Refs #12721 and #12700.
**What happened?**
The paid runner matrix failed ACPX and OpenCode startup before provider
session creation. The runner journal then replaced the original startup
error with an indeterminate recovery result. Native Codex saved a Plan
but rendered it only as a fallback card. A legacy Claude waiting reply
could also echo the reserved terminal marker before the answer arrived.
**Expected behavior**
Verified JavaScript providers must start from immutable
descriptor-backed artifacts. Returned startup failures must persist as
terminal failed command results. Native tool lifecycle updates must
preserve the `write_document` boundary. Pre-answer fixture output must
not contain the reserved terminal marker.
**Steps to reproduce**
1. Run the local provider cells in the Runner Full-Stack E2E workflow.
2. Observe ACPX and OpenCode fail during `session.open` before provider
execution.
3. Observe recovery report `execution_indeterminate` instead of the
original startup error.
4. Run the native Codex Plan cell and observe the fallback Plan card
after the tool activity row.
5. Run the legacy Claude structured-question resume cell and observe an
early marker echo in waiting prose.
**Paperclip version or commit**
`0f9452101740835ce0b1488a204bf48acd5bafc3`
**Deployment mode**
Local development with the paid GitHub Actions acceptance workflow.
## What Changed
- Bundle the ACPX sidecar and OpenCode proxy as self-contained Node ESM
entrypoints before hashing and verified descriptor launch.
- Anchor ACPX dynamic provider package resolution at a
controller-derived provider-pack root and keep that root out of the
provider child environment.
- Persist executor-returned startup errors as redacted durable failed
command results while retaining indeterminate recovery for true process
death.
- Coalesce sparse native tool items by stable ID so a late
`write_document` name, input, and result reach the transcript boundary
once.
- Forbid the structured-question fixture from spelling or announcing its
reserved terminal marker before the user answers.
## Verification
- Rust and TypeScript regression tests cover durable failed replay, true
crash ambiguity, bundle closure, package-root derivation, environment
filtering, exact Codex tool lifecycle coalescing, and prompt
determinism.
- Local execution is intentionally limited to formatters and static diff
checks. GitHub Actions will run tests, type checks, builds, and security
checks.
- After ordinary CI is green, scoped paid cells will validate one ACPX
launch, one OpenCode launch, native Codex Plan projection, and legacy
Claude structured resume before a complete matrix rerun.
- Prior failing matrix:
https://github.com/paperclipai/paperclip/actions/runs/33682434315
## Risks
- Bundling changes the bytes covered by provider launch hashes.
Provider-pack generation already hashes the final built files.
- ACPX still loads qualified provider packages dynamically. The
controller supplies a normalized package root, while existing version,
digest, path, and descriptor checks remain active.
- Durable `failed` is terminal. Replays return the same redacted result
and do not execute the provider effect twice.

## Thinking Path
> - Paperclip is the control plane for agents that perform work.
> - Paperclip Runner connects durable provider sessions to individual
task runs through PRP.
> - Provider continuity and per-run authority are different lifetimes.
> - The existing implementation mixed those lifetimes and lost event
metadata between provider frames, runnerd, persistence, API
sanitization, and the task thread.
> - That caused failed continuation, missing progress and Plans,
duplicate replies, hidden failures, and unsafe recovery.
> - This repair gives every heartbeat fresh authority, preserves
qualified provider-session continuity, and restores one lossless
presentation path without changing direct adapters.
## Linked Issues or Issue Description
**What happened?**
A second native heartbeat could reuse tickets, leases, command receipts,
sequence state, and run identity from the first heartbeat. Provider
phase and item identity could be lost before the UI read them. Redaction
could corrupt protocol discriminators while still missing malformed
credential tails. The task thread could fold progress into the final
response, hide failures, or show more than one final answer. Native
Codex also exposed approval modes that do not yet have a durable
approval bridge.
**Expected behavior**
Each heartbeat uses a new PRP authority epoch. Codex and OpenCode
preserve exact qualified provider sessions; ACPX emits an explicit
continuity event when its qualified process-replacement policy is used.
Every accepted provider event is presented, classified as internal, or
surfaced as unsupported. The task page shows chronological progress,
reasoning summaries, activity, Plans, interactions, terminal failures,
and exactly one final reply. Direct adapters retain their existing path.
**Steps to reproduce**
1. Enable the unified experimental Paperclip Runner setting.
2. Create a local native Codex, OpenCode, ACPX Claude, or ACPX Codex
agent.
3. Run response, Plan, structured-question/resume, restart,
cancellation, and failure scenarios.
4. Reload the task while active, waiting, failed, and settled.
5. On the old implementation, observe stale run authority, missing
classifications, incomplete output, or duplicated/folded replies.
**Paperclip version or commit**
The repair is based directly on `master` at
`87d05e194b643810d16d20612115acd01d735d43`.
**Deployment mode**
Local development with the embedded database.
Related work: Refs #12616, #12646, #12666, #12685, and #12700.
## What Changed
- Rotates PRP control-plane, outbox, ticket, lease, command, receipt,
and sequence authority for each heartbeat while carrying forward only a
validated provider-session identity.
- Reads `control-plane-state.json`, validates both durable schemas and
lifecycle values, resumes coherent current runs, archives qualified
settled authority, and quarantines malformed or mismatched scoped state
without moving ambiguous live legacy state.
- Preserves Codex provider phase and stable item identities so
commentary remains progress and only `final_answer` becomes final.
- Adds raw OpenCode HTTP/SSE boundary coverage and canonical reasoning
lifecycle mapping.
- Makes ACPX normalization lossless for visible reasoning, tool
lifecycle metadata, stable bounded identities, Plan revisions,
structured requests, failures, and qualified process replacement. Only
the compatible terminal assistant message is promoted as final.
- Applies schema-aware redaction before generic JWT-shaped detection and
scans every diagnostic string leaf. Malformed raw/escaped quoted
credential tails are redacted in both server and durable Rust state.
- Restores snapshot-style chronological task presentation, expandable
tool activity, inline Plan cards, visible waiting/resume/cancel/failure
states, and exactly one final answer.
- Makes `never` the only qualified native Codex permission mode and
rejects unsupported persisted native modes with remediation. OpenCode
and ACPX policies remain intact.
- Keeps the unified experimental Runner setting as the only enablement
flag. Onboarding and direct Codex, Claude, and OpenCode stay on their
legacy execution/finalization paths.
- Adds cross-language goldens, authority/recovery/fault coverage, exact
response/count assertions, and native plus legacy acceptance scenarios.
## Verification
- Pull-request GitHub Actions run Rust formatting/tests, TypeScript
checks, server/UI tests, builds, protocol drift checks, browser E2E, and
security scans.
- A separate workflow-only validation ref is pinned directly on this PR
head and runs the 35-cell paid local matrix: three core scenarios plus
structured-question resume and restart/resume for native Codex, native
OpenCode, ACPX Claude, ACPX Codex, and direct Codex/Claude/OpenCode.
Run: https://github.com/paperclipai/paperclip/actions/runs/33682434315
- Acceptance requires exact single visible replies, monotonic sequences,
matching envelope discriminators, one semantic terminal, one run
terminal, no unresolved interaction, no duplicate mutation, no secret
leakage, provider continuity, and zero native rows for direct adapters.
- Per maintainer direction, tests are running in GitHub Actions rather
than on the slower local host. Only formatters and static diff checks
were run locally.
## Risks
- Recovery from old or partial filesystem state is sensitive. The repair
fails closed, preserves active or unverifiable authority, and
quarantines only state whose scoped ownership is safe to move.
- Provider event formats can change. Closed validators and boundary
goldens turn new or malformed events into visible diagnostics instead of
silent drops.
- Shared task presentation could affect direct adapters. Runtime-fact
gating plus the direct-adapter matrix protect the existing path.
- Managed and remote providers are not qualified here. Shared code
continues to compile and fail safely, but live qualification is
deferred.

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

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

- The focused TypeScript, server, and UI suites passed 274 tests.
- `cargo test -p paperclip-runner-core --test native_provider_backend`
- The executable native provider integration suite passed 4 tests.
- `cargo test -p paperclip-runner-core --lib`

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

## Linked Issues or Issue Description
Refs #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.

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

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

- Base: master
- Next: additional qualified provider runtimes
## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The runner package keeps provider sessions durable across process
restarts.
> - The merged Codex ACPX backend can admit a new qualified session
through the package factory.
> - It cannot yet recover a settled session from a durable checkpoint.
> - Recovery must prove the same provider identity, runtime root,
workspace, and latest terminal settlement before it resumes.
> - ACPX cannot yet prove continuity for a provider turn that was active
when the process stopped.
> - This pull request recovers only settled Codex ACPX checkpoints and
rejects ambiguous or stale state.
> - The benefit is fail-closed restart recovery without repeated work,
silent session replacement, or recovery of an older semantic result.
## Linked Issues or Issue Description
Refs #12406
This pull request builds on the Codex ACPX backend route merged in
#12406. It adds only settled-session recovery and the package-local
durability and filesystem checks that recovery requires.
## What Changed
- Add settled-session recovery to the Codex ACPX harness driver and
advertise resume support for that bounded path.
- Keep provider recovery on the same persisted ACPX session. Do not
permit a replacement provider session.
- Require persisted run, normalized session, provider, profile,
workspace, permission, result, terminal, and recovery-policy identities
to agree.
- Reopen the provider with the exact persisted ACPX identity and reject
provider or qualification drift.
- Restore the last source sequence, terminal history, semantic result,
provider recovery policy, and normalized terminal fact before new work
can start.
- Clear a stale active-turn marker only when durable terminal history
proves that exact turn settled.
- Reject active-turn recovery when durable history cannot prove
provider-turn continuity.
- Require a semantic result to belong to the latest completed terminal
settlement.
- Reject an older completed semantic result when a later identical retry
failed or was interrupted.
- Reject resultless recovery unless the latest terminal turn completed
successfully.
- Bound terminal history and semantic-result recovery by entry count,
aggregate bytes, fingerprint bytes, node count, and nesting depth before
cloning or serializing persisted data.
- Read the private workspace record through pinned namespace,
runtime-root, record, and workspace identities.
- Reject symbolic links, substituted directories, replaced records,
invalid files, root workspaces, and workspace changes during admission.
- Keep the recovery workspace lease pinned and revalidate it at the host
and provider-spawn boundaries.
- Retain and close a workspace lease that resolves after cancellation.
Close a partially recovered provider session if lease cleanup fails.
- Stage a valid isolated Codex credential in the runtime-open-boundary
regression so the test reaches and proves the intended workspace
revalidation fence.
- Add focused recovery tests for settled checkpoints, terminal
ownership, stale semantic results, active turns, identity drift, bounded
persisted data, cancellation, directory substitution, record
replacement, and spawn-boundary workspace replacement.
## Verification
- Replay base: `30ef14edd4e7290d9eac43ca7b7835611933cc74` (`master`
after #12406 merged).
- Exact replay head: `3d1b16d5cda2dd72f83785c921a025cc57aab8d6`.
- Stable patch ID for the exact replay delta:
`10742d7db00f801b5723e7a8582c637261ceb0dd`. The source-stack combined
patch was `4d7c9de72a0a30f6e33c935c092b745fe414c588`; the replay
preserves the newer unconditional provider process-group containment
from `master` while adding recovery workspace revalidation before spawn,
plus the exact-head credential fixture correction exposed by GitHub
Actions.
- The exact pull request delta contains exactly 14 files:

- `packages/paperclip-runner/src/native-session-runtime.ts`
- `packages/paperclip-runner/src/native-session-runtime.test.ts`
- The exact combined delta is 2,279 additions and 73 deletions.
- This delta does not change dependencies, `pnpm-lock.yaml`, workspace
configuration, workflows, migrations, server selection, UI behavior, or
public package exports.
- Focused GitHub recovery tests: **PASS**. The exact-head Build job
passed the harness backend, native runtime, Codex ACPX driver, runtime
host, runtime sandbox, runtime adapter, and backend factory suites as
part of all 751 TypeScript runner tests.
- GitHub Actions: **PASS** for exact head
`3d1b16d5cda2dd72f83785c921a025cc57aab8d6`. Every applicable job passed.
The Storybook visual regression skipped intentionally because this
package-only delta does not touch UI or Storybook paths.
- Security checks: **PASS** for the exact head. Superagent, Snyk, both
Socket checks, and contributor trust completed successfully.
- Greptile: **5/5** for the exact head, with no open P1/P2 findings,
recommendations, or follow-ups.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for the replayed revision.
## Risks
This change has medium package-local risk because it admits persisted
state back into a provider session. Recovery fails closed when an active
provider turn has no matching terminal fingerprint, when a semantic
result is not owned by the latest completed settlement, when any durable
identity changes, or when the workspace cannot remain pinned through
provider spawn. Recovery never selects a replacement provider session.
Bounds prevent oversized or deeply nested persisted state from consuming
unbounded work before validation. The workspace lease prevents path
substitution during recovery admission. Existing direct adapters and the
Codex app-server driver do not use this ACPX recovery route. This change
does not add a migration, dependency, lockfile update, workflow, server
route, UI surface, public export, or production rollout flag.

## Linked Issues or Issue Description
Refs #12405
This pull request builds on the Codex ACPX harness driver merged in
#12405. It adds only the package-local backend factory route for that
driver.
## What Changed
- Add an internal Codex ACPX native backend constructor.
- Require provider kind `acpx` and agent `codex` at the
provider-specific boundary.
- Resolve the qualified Codex ACPX profile for the requested model.
- Compare the persisted driver kind, protocol version, ACPX version,
agent profile, package versions, runtime package fields, and command
digest with the qualified profile.
- Compose the existing native system instructions and task constraints
for the Codex ACPX driver.
- Route qualified Codex ACPX inputs through the native backend factory
only when the caller supplies an explicit instance runtime directory.
- Pass the scoped environment, managed credential source, dynamic tools,
and ACPX tool handler through the factory boundary.
- Keep Pi, Claude, OpenCode, managed Claude, AgentCore, and every other
deferred ACPX agent unavailable.
- Add factory tests for qualified construction, the explicit
runtime-root requirement, unsupported ACPX agents, and
qualification-snapshot drift.
- Keep ACPX construction lazy. Reading the backend descriptor does not
start ACPX transport or a provider process.
## Verification
- Replay base: `74aabb7ea6c5cf373f2254e5f854a5233b745ddc` (`master`
after #12405 merged).
- Exact replay head: `827090a0cff870eedb99fa1b5cfda8bb87efa515`.
- Stable patch ID for the exact replay delta:
`e0f6733a5a124a4fb93155257358b966c354a176` (identical to the original
narrow source patch).
- The exact pull request delta contains exactly three files:
- `packages/paperclip-runner/src/backends/codex-acpx-native-backend.ts`
- `packages/paperclip-runner/src/backends/native-backend-factory.ts`
-
`packages/paperclip-runner/src/backends/native-backend-factory.test.ts`
- The exact source delta is 193 additions and 10 deletions.
- This delta does not change dependencies, `pnpm-lock.yaml`, workspace
configuration, workflows, migrations, server selection, UI behavior, or
public package exports.
- Focused GitHub test coverage: **PASS**. The exact-head Build job
passed all six native backend factory tests and all 720 TypeScript
runner tests.
- GitHub Actions: **PASS** for exact head
`827090a0cff870eedb99fa1b5cfda8bb87efa515`. Every applicable job passed.
Failed-job-only reruns cleared unrelated database timeout and server
concurrency flakes without changing the patch. The Storybook visual
regression skipped intentionally because this backend-only delta does
not touch UI or Storybook paths.
- Security checks: **PASS** for the exact head. Superagent, Snyk, both
Socket checks, and contributor trust completed successfully.
- Greptile: **5/5** for the exact head, with no open P1/P2 findings,
recommendations, or follow-ups.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for the replayed revision.
## Risks
This change has low package-local runtime risk. It adds a new branch to
the native backend factory, but no server or runnerd factory selects an
ACPX execution in this pull request. The route fails closed when the
runtime directory is absent, the agent is not Codex, or the persisted
qualification snapshot differs from the qualified Codex profile. The
constructor repeats the provider-kind and agent checks as a second
boundary. Existing direct adapters do not use this route. The change
does not add a migration, dependency, lockfile update, workflow, UI
surface, public export, or production rollout flag.

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

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The package now has bounded Codex transport, security, question,
diff, value, and thread helpers
> - Those isolated boundaries can now be composed into one provider
session lifecycle

terminals, and recovery invariants

## Linked Issues or Issue Description
**Subsystem affected**
`packages/paperclip-runner` Codex app-server session driver.
**Problem or motivation**
The runner needs a production-shaped Codex session implementation that
turns provider facts into canonical PRP events while keeping task
identity, semantic completion, runtime input, and recovery under
controller authority.
**Proposed solution**
Compose the previously reviewed transport and normalization boundaries
into a Codex-only harness driver with session open/resume, turns,
streaming events, semantic tools, structured questions, goals, lineage,
usage, cancellation, reconciliation, and deterministic persisted
snapshots.
**Alternatives considered**
Keeping the full implementation in one initial transport pull request
would obscure the trust boundaries. Adding the deferred ACPX or OpenCode
paths here would also broaden the provider scope beyond the Codex-first
series.
**Roadmap alignment**
This implements the Codex provider slice inside the package. It does not
enable the runner adapter or change any existing direct adapter path.
## What Changed
- Added the Codex app-server harness driver and session lifecycle.
- Added controller-bound semantic completion and terminal handling.
- Added runtime requests, structured questions, goals, lineage, usage,
steering, interruption, and recovery.
- Added workspace diff and file-reference projection.
- Connected bounded/redacted provider data and notification identity
checks.
- Kept deferred provider identities and replacement behavior out of the
Codex-only driver.
- Added 62 focused driver cases covering lifecycle, security, recovery,
and protocol failures.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript` (34
files, 337 tests)
- `pnpm -r typecheck`
- `pnpm build`
- The focused Codex driver suite has 62 passing cases.
## Risks
The main risks are accepting provider events from the wrong session,
duplicating terminal facts, retaining unsafe provider data, or resuming
a different session. Tests cover pre-turn, cross-thread, stale-turn,
post-terminal, duplicate-result, cancellation, transport loss, provider
identity, workspace, redaction, structured input, and recovery cases.
## Model Used
OpenAI Codex with GPT-5.6 and repository tool use.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The runner needs repeatable tests at the provider and control-plane
boundaries
> - Network services and live providers cannot produce deterministic
conformance results
> - Small in-memory adapters can exercise the same public contracts
without production side effects

adapter, and fixture runner

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

work
> - The Paperclip Runner package needs one provider-neutral session loop
> - Native execution contracts now define the accepted input and output
> - Backends still need bounded execution, recovery, and control-plane

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