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

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip Runner now has a durable PRP transport and a Codex
provider bridge.
> - Codex must use stable, provider-neutral action contracts before
Paperclip can grant run-scoped tool access.
> - A catalog must describe actions without granting permission to
discover or invoke them.
> - Generated inventory must stay synchronized with its TypeScript
source.
> - This pull request adds the canonical Codex-spine semantic action
catalog inside the runner package.
> - The benefit is a small review unit for schemas and inventory before
authorization and dispatch land.
## 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.
