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

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

Refs #12111
Refs #12169
Refs #12176
**Subsystem affected**
Cross-cutting. The change affects the runner package, server
orchestration, shared settings, and adapter configuration UI.
**Problem or motivation**
The hidden PRP coordinator cannot execute a real heartbeat. The
application also needs an explicit rollout boundary before it can expose
the experimental runner. Existing direct adapters must keep their
current execution and finalization behavior.
**Proposed solution**
Add `paperclip_runner` as a Codex-only adapter behind the default-off
`enableNativeRunner` instance flag. Select the native runtime only for
that adapter. Persist the run binding before runnerd starts. Wait for
the durable PRP result and terminal event. Resume the real Codex
provider thread on later heartbeats. Keep persisted native runs readable
and recoverable after the flag changes.
**Alternatives considered**
The server could route `codex_local` through runnerd. That option would
change an existing adapter and weaken rollback safety. The server could
expose all providers now. That option would add unreviewed provider
behavior. The build could depend on a prebuilt runner binary. That
option would make source builds architecture-dependent and difficult to
verify.
**Roadmap alignment**
This work supports the shipped enforced-outcomes, governed-tool, and
self-healing-run milestones. It does not add a new roadmap surface. It
is the guarded execution step after the merged hidden runner boundaries.
**Additional context**
This is the next replacement for the closed large runner pull request.
Task-thread presentation remains a separate follow-up so this change can
preserve the current direct-adapter UI.
## What Changed
- Add `paperclip_runner` as an explicit Codex-only adapter.
- Add the default-off `enableNativeRunner` instance flag.
- Reject fresh create, hire, import, switch, and execution requests
while the flag is off.
- Allow edits to persisted runner agents while the flag is off.
- Recover an already persisted native run even after the flag is
disabled.
- Keep every built-in direct adapter on its existing runtime path.
- Persist an immutable native run binding and revisioned completion
contract before runnerd starts.
- Execute server to PRP to runnerd to Codex to server through the hidden
coordinator.
- Validate the durable result against the terminal event and exact
completion criteria before finalization.
- Preserve the Codex provider thread ID and use `thread/resume` on the
next heartbeat.
- Strip unsupported Codex configuration fields from the experimental
adapter.
- Build a target-native release runner binary from source and vendor it
into the server distribution.
- Install Rust only in the Docker build stage. Do not add a workflow or
lockfile change.
- Stop the runner process group on completion, cancellation, and forced
shutdown.
## Verification
- Run `pnpm --filter @paperclipai/paperclip-runner check:all`. All 69
TypeScript tests and 58 Rust tests pass. Protocol, conformance, replay,
formatting, and generated-file checks pass.
- Run the 12 focused adapter, settings, runtime-selection, coordinator,
direct-isolation, and real Codex integration test files. All 186 tests
pass.
- The real integration test uses PostgreSQL, HTTP, WebSocket, runnerd,
and a fake Codex app server. It proves one `thread/start` followed by
one `thread/resume`.
- Run `pnpm -r typecheck`.
- Run `pnpm build`.
- Run `pnpm check:token-gates`.
- Build the Docker `build` target from a clean context. Confirm that the
server distribution contains an executable `paperclip-runnerd` built
with Debian Rust 1.85.
- Start the server through the source-mode tsx entry point with the
package `dist` directory absent. Confirm the vendor shim resolves source
exports and the server boots.
- Run `pnpm test:run` twice. On this macOS host, 405 files pass and 1
file skips. Eight untouched workspace and loopback tests fail because
macOS resolves `/tmp` and `/var` through `/private` and because
PID-derived test ports exceed 65535. Linux CI must pass the full suite.
- Confirm that the diff contains 52 files. Confirm that it contains no
`.github` or `pnpm-lock.yaml` change.
## Risks
- The feature flag is off by default. A fresh native start fails with a
stable error while the flag is off.
- A persisted native run remains recoverable after the flag changes.
This prevents rollout changes from corrupting recorded work.
- Only local Codex execution is accepted. Other providers and remote
work modes fail closed.
- Existing direct adapters do not start runnerd, create native rows, use
native status arbitration, or enter native finalization.
- The runner receives its one-use bootstrap ticket through the child
environment. The server does not put the ticket in command arguments or
logs.
- The server validates the company, task, agent, run, runner, session,
completion contract, result, and terminal binding before it accepts
completion.
- The build compiles a target-native Rust binary. Cross-platform release
packaging remains a later concern. Source builds and Docker builds
compile for their current target.
- Docker needs enough build memory for the existing server TypeScript
compile. The Docker build stage sets a 4 GB V8 heap limit.

## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting. This pull request extends private runner infrastructure
in `packages/paperclip-runner`.
**Problem or motivation**
The Codex provider bridge has no canonical description of the Paperclip
actions that a later authorization layer can project into a run.
Independent operation lists can drift in names, claims, task modes,
effects, and input bounds.
**Proposed solution**
Add one immutable v1 catalog for the first 27 Codex-spine actions. Give
each action a stable identifier, placement, effect, required claims,
supported task modes, and JSON Schema input and output contracts.
Generate a deterministic JSON inventory from that source and fail
package checks on drift.
**Alternatives considered**
The combined runner branch contains larger live and scenario catalogs
with authorization, bindings, labs, and other providers. That change is
too large for this review unit. A generic API escape hatch would also
bypass the operation-level boundary, so this catalog excludes it.
**Roadmap alignment**
This work supports the governed tool access direction in `ROADMAP.md`.
It does not add a tool gateway, application binding, server endpoint, or
production authorization decision.
**Additional context**
Refs #12111 and #11962. Pull request #12111 was squash-merged first.
This branch starts at the resulting `master` commit. Its delta is 10
files.
## What Changed
- Added 27 versioned, provider-neutral semantic action declarations for
the Codex spine.
- Added bounded JSON Schema input contracts and normalized operation
receipt output contracts.
- Added placement, effect, claim, mode, and role metadata.
- Added a deeply frozen public catalog and an operation lookup helper.
- Added a deterministic checked-in JSON inventory and generation
commands.
- Added a byte-for-byte drift gate to the package build.
- Added AJV schema compilation, mutation-bound, forged-field,
immutability, inventory, and non-executable-boundary tests.
- Exported only the catalog types and declarations from the existing
package root.
- Documented that catalog membership does not grant discovery,
authorization, dispatch, or application binding.
- Kept server code, UI code, other providers, scenario-only actions,
labs, generic API access, authorization, dispatch, and receipts
processing out of this pull request.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner check:all` passes.
- TypeScript protocol tests pass: 8 Node tests and 49 Vitest tests.
- All package Rust tests and conformance and replay parity checks pass.
- `pnpm --filter @paperclipai/paperclip-runner
check:semantic-action-catalog` passes.
- `pnpm -r typecheck` passes.
- `pnpm build` passes.
- `pnpm check:token-gates` passes.
- Prettier and `git diff --check` pass for the changed source and
documentation files.
- The generated catalog matches its source byte for byte.
- The secret scan is clean.
- The delta against `master` is 10 files. `pnpm-lock.yaml` is unchanged.
- `pnpm test:run` completed locally with 4,692 passing tests, 19 skipped
tests, and 24 failures in 8 unchanged server test files. The failures
reproduce the established local macOS path-alias, listener, and
workspace-runtime baseline. No changed-file test failed. Linux CI
remains the repository handoff authority.
- The full Linux PR workflow passes, including the aggregate `verify`
gate.
- Snyk, Socket, Superagent security, and supply-chain checks pass.
- Greptile is 5/5 with no actionable comments, recommendations, or
follow-ups.
- Storybook visual regression skipped by design because this pull
request changes no UI file.
- Browser and migration tests are not applicable because this pull
request changes no server, UI, database, or migration file.
## Risks
Production behavior is unchanged because no consumer projects this
catalog into a provider run. The main risks are contract drift,
unbounded mutation input, forged scope fields, accidental executable
authority, and generated inventory drift. Closed input schemas, explicit
bounds, a frozen catalog, tests, and the byte drift gate cover these
risks. The later authorization layer must still bind every action to the
active run and company before discovery or invocation.
I checked `ROADMAP.md`. This change is private contract infrastructure
for the governed tool access direction. It does not duplicate a shipped
or public product surface.
## Model Used
OpenAI Codex with GPT-5 was used. The exact serving model ID and context
size were not exposed. The model used high reasoning, repository tools,
GitHub tools, and local code execution.

## Linked Issues or Issue Description
**Subsystem affected**
This change affects the private `@paperclipai/paperclip-runner` package.
It does not change an existing server or adapter execution path.
**Problem or motivation**
The PRP v1 schemas do not yet provide TypeScript types, runtime
validators, normalized result handling, or a deterministic session
projection. Later Rust, transport, provider, and server work needs one
tested TypeScript oracle instead of separate interpretations.
**Proposed solution**
Generate a checked-in TypeScript schema bundle from the PRP v1 sources.
Add derived types, AJV validation, result and question validation,
deterministic replay, a reducer, and generated golden snapshots. Export
only these implemented root-package surfaces.
**Alternatives considered**
The combined runner branch adds the TypeScript contracts together with
Rust, providers, semantic authorization, SDKs, labs, and server
behavior. That delta is too large for normal review. Handwritten
duplicate protocol types would also create a drift risk.
**Roadmap alignment**
This work supports the governed tool and control-plane direction in
`ROADMAP.md`. It does not enable a new production adapter or endpoint.
**Additional context**
Refs #12087 and #11962. This pull request was prepared on #12087, then
rebased onto its squash merge before opening. The current delta against
`master` is 37 files.
## What Changed
- Added JSON-Schema-derived PRP v1 types and AJV runtime validation.
- Added fail-closed required-version checks and cross-envelope binding
checks.
- Added provider-neutral completion-result and structured-question
contracts.
- Added normalization for accepted legacy provider result aliases before
strict validation.
- Added a deterministic session reducer for replay, duplicate delivery,
source gaps, requests, items, results, and terminal state.
- Added generated replay snapshots and compact parity summaries for six
accepted fixtures.
- Added schema-bundle, manifest, and replay-golden drift gates.
- Added only the root package export. Deferred testing, SDK, evaluation,
lab, provider, and browser entry points remain unavailable.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test` passed with 8
protocol tests and 44 TypeScript tests.
- `pnpm --filter @paperclipai/paperclip-runner typecheck` passed.
- `pnpm --filter @paperclipai/paperclip-runner check:replay-goldens`
passed.
- `pnpm -r typecheck` passed.
- `pnpm build` passed.
- `pnpm check:token-gates` passed.
- `git diff --check` passed.
- The delta against its declared base is 37 files.
- `pnpm test:run` was executed locally. The package tests pass, while
the macOS repository run retains the unchanged local-environment
failures documented on #12087. The complete Linux CI matrix must pass on
this commit.
- A scoped scan found no secret-like values, internal references, or
deferred-provider file names.
- Greptile found an unbounded sequence-gap allocation. Commit `4a405c17`
caps detailed missing IDs at 256, records the full missing count and
truncation state, and rejects sequence values above the exact JavaScript
integer range. The focused tests, workspace typecheck, build, and token
gates pass after this fix.
## Risks
Low production risk. The package remains private. This change adds no
process, network endpoint, provider bridge, server integration, database
change, or execution selection. The main risk is protocol interpretation
drift. Generated schema and replay gates detect that drift. Browser and
CSP-specific validator packaging remains deferred to its later package
boundary.
I checked `ROADMAP.md`. This change defines contracts for planned
control-plane work and does not add overlapping product behavior.
## Model Used
OpenAI Codex with GPT-5 was used. The exact serving model ID and context
size were not exposed. The model used high reasoning, repository tools,
GitHub tools, and local code execution.

## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting. This pull request adds a private package contract for
later server, TypeScript, and Rust work.
**Problem or motivation**
Paperclip Runner does not have a small language-neutral protocol
boundary on `master`. A runtime implementation without this boundary can
drift between languages, accept unsupported required versions, or
silently change canonical fixtures.
**Proposed solution**
Add PRP v1 JSON Schemas, accepted and rejected fixtures, a Codex
structured-question fixture, and a generated SHA-256 manifest. Run
compatibility and manifest checks during the package build. Keep the
package private and export nothing in this pull request.
**Alternatives considered**
The combined runner branch contains schemas together with providers,
SDKs, labs, and server behavior. That change is too large for normal
review. Generating TypeScript validators in this pull request would also
cross into the next review unit.
**Roadmap alignment**
This contract supports the governed tool and control-plane direction in
`ROADMAP.md`. It does not enable a new production adapter or endpoint.
**Additional context**
Refs #12084 and #11962. This pull request was reviewed as a stack on
#12084, then rebased and retargeted to `master` after #12084 merged. The
current delta is 38 files.
## What Changed
- Added 20 PRP v1 JSON Schemas with stable identifiers and resolved
references, including explicit cross-language conformance input and
output schemas.
- Added canonical replay, cross-language, and Codex question fixtures.
- Added accepted cases for additive optional fields and a rejected case
for an unsupported required protocol version.
- Added a deterministic manifest with SHA-256 digests for every schema
and fixture.
- Added package-local schema-instance, schema-reference, compatibility,
question-ID, conformance-pair, and drift checks.
- Added a private workspace package with no public exports and no
production runtime behavior.
- Added the package manifest to the Docker dependency-stage inventory
required for every workspace package. This does not copy or build runner
runtime code into the production image.
- Kept the provider descriptor and question fixture Codex-only. No
deferred provider package or dependency is present.
## Verification
- `pnpm install --frozen-lockfile` passed with Node 24.19.0 and pnpm
9.15.4. No lockfile change is committed.
- `pnpm --filter @paperclipai/paperclip-runner check:protocol` passed
with 8 tests.
- The committed AJV 2020-12 gate accepted every canonical v1 replay,
question, and cross-language conformance fixture. It rejected the
required v2 fixture, a replay fixture with a missing required command
ID, and conformance output with a missing session ID.
- `pnpm -r typecheck` passed.
- `pnpm build` passed and ran the protocol manifest drift check.
- `pnpm check:token-gates` passed.
- `node ./scripts/check-docker-deps-stage.mjs` passed.
- `git diff --check` passed.
- The delta against its declared base is 38 files.
- `pnpm test:run` completed with 4,687 passing tests, 19 skipped tests,
and 29 failures across 9 unchanged server files. The failures reproduce
macOS path aliases, local listener probes, workspace-runtime
assumptions, and one connection-retry timeout. No changed-file test
failed. Linux CI must pass before this pull request is ready.
- `pnpm check:tokens` reports existing personal-name references outside
this pull request. A scoped scan of `packages/paperclip-runner` found no
secret-like values, internal references, or deferred-provider names.
- PR #12084 was squash-merged, and this branch was rebased onto that
merge and retargeted to `master`. The first master-base policy run
correctly caught the missing Docker dependency-stage manifest copy;
commit `4fa1ea7c` fixes that gate, and the complete Linux matrix is
green.
- Serialized server shard 1 initially hit an unchanged heartbeat
test-harness timeout and a later assertion in the same file. Its
isolated rerun passed in 3m57s. All other shards passed on their first
attempt.
- Greptile reviewed the final commit at 5/5 with no blocking failure.
Both earlier actionable validation threads are resolved, and no review
thread remains open.
## Risks
Low production risk. The package is private and has no exports, server
adapter, endpoint, or process. AJV is a package-only development
dependency that the server workspace already uses. The main risk is
contract churn before the TypeScript and Rust consumers land. The
generated manifest and compatibility fixtures make that churn explicit.
I checked `ROADMAP.md`. This change defines a contract for planned
control-plane work and does not add overlapping product behavior.
## Model Used
OpenAI Codex with GPT-5 was used. The exact serving model ID and context
size were not exposed. The model used high reasoning, repository tools,
GitHub tools, and local code execution.
