## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The Paperclip Runner keeps durable run and provider state outside
one server process.
> - A server restart can leave that runner alive or can interrupt it
after a provider checkpoint.
> - The old startup path used handoff intent and PID evidence, but it
did not reconstruct native ownership.
> - That gap could block the issue, create a replacement run, or start
duplicate provider work.
> - This pull request adds durable same-run recovery for coordinated and
uncoordinated restarts.
> - The benefit is exact recovery of the run, runner, session, provider,
steering, and finalization state.
## Linked Issues or Issue Description
Refs #9628. That pull request added earlier local-adapter hot-restart
work. This change adds native PRP authority reconstruction and same-run
provider resume.
Refs #10935. That pull request handles missing hot-restart snapshots.
This change also supports hard restarts with no snapshot.
Refs #11624. That pull request prevents unsafe retry after an adopted
legacy process exits. This change reconciles native terminal evidence
before provider recovery.
Refs #12070. That pull request improves process liveness checks. This
change also binds recovery to a process-start fingerprint and fails
closed on ambiguity.
**What happened?**
The server could record hot-restart intent, but startup did not rebuild
native runner ownership. A live runner could not re-register its PRP
authority. A dead runner could not resume the exact native and provider
session on the same heartbeat run. Generic recovery could then block the
issue or create replacement work.
**Expected behavior**
A live native runner must reconnect with the same PID and logical
identities. A dead runner must resume the same durable session and
heartbeat run with only a new operating-system PID. A proposed or
terminal result must finalize once before any provider turn starts.
Ambiguous process or session evidence must stay blocked without a signal
or duplicate spawn.
**Steps to reproduce**
1. Start a Paperclip Runner heartbeat and wait for an active provider
turn.
2. Restart only the Paperclip server, with or without a hot-restart
marker.
3. Observe that the old startup path does not reconstruct the native
control-plane authority.
4. Kill both the server and runner after a provider checkpoint.
5. Observe that the old path cannot resume the exact native session on
the original heartbeat run.
**Paperclip version or commit**
The defect was reproduced from commit
`1991f31fd53e7f7794d5c2e4b93be384ade2b41d`. This branch is rebased onto
the current `master`.
**Deployment mode**
Local development and self-hosted server deployments that use the local
Paperclip Runner.
## What Changed
- Added correlated hot-restart requests and version-compatible native
handoff fields.
- Added controller boot identity, process-start identity, controller
generation, recovery state, request id, and bounded history to the
native finalization ledger.
- Added transactional recovery claims for live-runner reattach,
dead-runner resume, and incomplete bootstrap.
- Added fail-closed ownership takeover rules and process identity
validation.
- Added live runner adoption to the local runner transport without a
duplicate spawn.
- Added same-run provider checkpoint resume and legacy retry-row
compatibility.
- Reconciled proposed and terminal results before runner or provider
recovery.
- Bound the HTTP and PRP listener before startup recovery and delayed
scheduling and generic reapers until classification completes.
- Added restart-aware health diagnostics, run-log recovery transitions,
durable runner diagnostics, and bounded shutdown finalizer draining.
- Moved restart-survivable diagnostics into runner-owned, pre-redacted
bounded writes; raw stdout and stderr are never persisted.
- Added process-start fencing for controller, runner, and provider PIDs;
startup classifies every candidate without an implicit cap.
- Added crash-recoverable, contention-safe development restart-request
coordination and failed-startup listener cleanup.
- Added a credential-free real-process restart suite for eight restart,
scale, and identity scenarios.
- Documented native restart operation, persistence, diagnostics, and
verification.
## Verification
- The documented native restart commands passed. They ran eight
real-process/database recovery scenarios and the live runner adoption
transport test.
- Native executor tests passed: 111 tests.
- Heartbeat recovery tests passed: 124 tests.
- Hot restart, health, and shutdown tests passed: 52 tests.
- The broader affected server suite passed: 350 tests.
- Focused native recovery and startup tests passed: 49 tests.
- Runner transport and control-plane tests passed: 63 tests.
- Runner-owned diagnostic tests passed for write-time bounding,
credential redaction, private file modes, and raw stream
non-persistence.
- Development restart coordination tests passed: 11 tests.
- Database migration checks and the partial-application/replay
regression test passed.
- Server, database, and Paperclip Runner typechecks passed.
- `git diff --check` passed.
- Full Paperclip PR CI passed, including build, canary, all five general
server shards, all five serialized server shards, all three browser E2E
shards, workspace suites, and release-registry verification.
- Greptile completed at 5/5 with no outstanding findings,
recommendations, follow-ups, or open review threads.
## Risks
- Moderate risk. This changes startup ordering and ownership transfer
for active native runs.
- The migration adds nullable columns and does not rewrite existing
rows.
- Recovery fails closed when process or durable session identity is
incomplete or contradictory.
- The first implementation supports the local Paperclip Runner. Remote
targets keep their existing behavior.
- The real-process suite covers cleanup and asserts that no runner or
provider process survives each test.

## Model Used
- OpenAI Codex with GPT-5. The runtime did not expose a more specific
model revision or context-window size. Repository editing, shell
execution, database tests, and real-process test execution were enabled.

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

--lib --locked` (161 tests)
- focused ACPX provider-event tests (10 tests)
- The rebased PR changes 92 files. `pnpm-lock.yaml` is unchanged.
I did not run paid live provider jobs or provision AWS resources. Those
checks need credentials and can create cost.
## Risks
The paid workflows can create provider cost. They require an allowlisted
original and triggering actor, the protected `runner-e2e-paid`
environment, explicit opt-in variables, and cost limits. The four
provider credentials exist only in that master-only environment, which
requires allowlisted reviewer approval and disables administrator
bypass; repository and organization Actions scopes contain no copies.
Provider usage arrives after a billable request, so the live guard
cannot prevent one request from crossing a threshold. It interrupts
immediately on the first reported threshold hit and permits no
continuation.
Visual evidence can contain secrets rendered as pixels. PNG/WebM remain
only in access-controlled workflow artifacts; SVG and per-attempt XML
are excluded, and S3/Pages receive a pruned structured dashboard.
The AWS scripts can create cloud resources. They use explicit commands,
least-privilege roles, KMS encryption, saved nonsecret metadata, and
explicit teardown.
This pull request does not enable the experimental native runner for
existing instances.

> - Evaluation code must stay separate from provider launch and
production orchestration.
> - Offline fixtures need stable compatibility, scoring, traceability,

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

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

`packages/paperclip-runner` — runner SDK, conformance tools, and
developer tooling.
**Problem or motivation**
The production runner spine is present, but package consumers cannot
build deterministic integrations, inspect sessions, or verify
provider-neutral behavior through supported surfaces.
**Proposed solution**
Add browser, React, standalone, live-session, scenario, conformance, and
evaluation surfaces. Add generated contract inventories and
package-local verification scripts. Keep production application routing
unchanged.
**Alternatives considered**
We considered splitting each generated catalog, SDK surface, and demo
into separate pull requests. Those changes share exports, fixtures, and
drift gates. Splitting them would create intermediate package states
that do not build.
**Roadmap alignment**
No overlapping item appears in `ROADMAP.md`. This work extends the
runner package that is already on `master`.
## What Changed
- Add browser, React, standalone, live-session, and issue-thread SDK
surfaces.
- Add deterministic mock control-plane, scenario, conformance, replay,
and evaluation tools.
- Add bounded Codex, OpenCode, and ACPX development transports and
fixtures.
- Keep deferred managed-provider execution fail-closed. Persisted
compatibility data remains readable.
- Add generated capability inventories with their source files and drift
checks.
- Add examples, package documentation, browser checks, and
clean-consumer checks.
- Preserve the reviewed protocol bounds, replay compatibility aliases,
process environment isolation, and semantic redaction limits.
- Update the ACPX package patch that the existing workspace patch
registry already tracks.
- Do not change `pnpm-lock.yaml`, repository workflows, server runtime
selection, or the application UI.
## Verification
GitHub Actions is the verification authority for this pull request. The
repository CI, package TypeScript and Rust checks, package tests,
generated-output drift checks, browser checks, security scans, and
Greptile review must pass on the exact head.
Local test suites were not run because this series uses parallel GitHub
Actions for verification.
## Risks
This is a large greenfield package change. The main risks are public
export drift, generated-output drift, and optional React consumer
compatibility. Package boundary checks, clean-consumer checks, and
browser tests cover those risks. Production adapter selection and server
execution are outside this pull request.
## Stack
1. **This PR:** runner SDK and developer tooling.
2. [Codex production server
integration](https://github.com/paperclipai/paperclip/pull/12616).
3. [Provider-neutral task-thread
UI](https://github.com/paperclipai/paperclip/pull/12617).
## Model Used
OpenAI Codex, GPT-5, high-reasoning mode, with tool use and code
execution.
