## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The runner package now has protocol, transport, provider, catalog, and authorization foundations. > - Its first upstream package boundary should expose only the implemented runtime and test-helper surfaces. > - Rust correctness belongs in the repository existing build verification, without introducing a parallel release process. > - Direct package creation must build the files declared by the package manifest. > - This pull request defines the minimal package API and verifies the optimized runner binaries in the existing PR and release Build jobs. > - The benefit is a production-ready runner package boundary with minimal build-process change. ## Linked Issues or Issue Description Refs #11962 This pull request replaces one bounded part of the archived large runner change. It follows the package-local authorization change in #12126. ## What Changed - Export only `@paperclipai/paperclip-runner` and `@paperclipai/paperclip-runner/testing`. - Keep Node-only fixture loading and semantic conformance helpers out of the runtime root. - Add a provider-neutral semantic conformance kit with stable JSON comparison and fail-closed input checks. - Keep deferred SDK, eval, browser, React, lab, and command surfaces private. - Pin the runner Rust toolchain to 1.97.1 with the minimal profile and `rustfmt`. - Run the Rust workspace tests in release mode. - Launch the optimized `paperclip-runnerd` and fake-harness binaries in process-level integration coverage. - Add one `pnpm --filter @paperclipai/paperclip-runner check:all` step to each existing PR and release Build job. - Make the existing server `prepack` lifecycle run its existing build after it prepares UI assets. - Document that no production adapter starts runnerd yet. This revision adds no standalone GitHub Actions job. It adds no server runner dependency or runner vendoring. It adds no Docker bootstrap or clean-consumer harness. It does not change `pnpm-lock.yaml`. ## Verification - `pnpm --filter @paperclipai/paperclip-runner check:all` - 66 TypeScript tests - 8 protocol contract tests - 56 Rust unit and integration tests - Release-mode integration coverage launches the optimized runnerd and fake-harness binaries. - `pnpm --filter @paperclipai/server exec vitest run src/__tests__/server-package-build-script.test.ts` (2 tests) - Clean `pnpm pack` from `server/` rebuilt the server and produced both `package/dist/index.js` and `package/dist/index.d.ts`. - `node --test scripts/__tests__/release-verify-workflow.test.mjs` (8 tests) - `pnpm -r typecheck` - `pnpm build` - `pnpm check:token-gates` - `git diff --check` - No `pnpm-lock.yaml` diff. - The diff changes 12 files. ## Risks The runner adds Rust work to the existing Build jobs. These jobs can take longer on a cold cache. The pinned toolchain makes contributor and CI behavior reproducible. Cargo tests use `--release` to verify optimized executables. The server prepack lifecycle now performs the build that its published entry points require. This can make direct server packing slower. This pull request does not wire runnerd into the server. It does not select runnerd for any adapter. Existing application execution and finalization paths remain unchanged. ## Model Used OpenAI Codex with GPT-5. Agentic coding mode used repository tools, code execution, and automated tests. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge Co-authored-by: Paperclip <noreply@paperclip.ing>
Paperclip Runner
This private workspace package contains the staged Paperclip Runner work.
The package currently exposes only the language-neutral PRP v1 TypeScript contract, provider-neutral structured questions and responses, deterministic fixture validation/replay, structured-result normalization, and the session reducer oracle. It also contains a package-local Rust runner, scripted fake harness, bounded process supervisor, cross-language replay oracle, and durable PRP transport. The transport authenticates and encrypts loopback WebSocket sessions, persists an ACK-driven outbox and command journal, and reconnects with a short-lived lease. The Rust runner now includes a Codex-only app-server provider bridge with durable thread resume, cancellation, structured questions, and provider-neutral event normalization. No server code starts or invokes it. The package also publishes the canonical semantic action declarations and their input and output schemas. Its package-local dispatcher projects only bound, run-authorized actions and emits redacted semantic receipts. It does not add application bindings, a server adapter, or production Paperclip behavior.
The first and only installed provider is Codex. Dynamic semantic tools remain
undiscoverable because no production application binding or server authority
has landed. Catalog membership alone does not grant authority. See
SEMANTIC_ACTIONS.md for the catalog boundary.
The package has two initial public surfaces:
@paperclipai/paperclip-runnercontains runtime contracts, validation, replay/reducer logic, the semantic catalog, and the authorization dispatcher.@paperclipai/paperclip-runner/testingadds Node-only fixture loading and a provider-neutral semantic conformance kit for deterministic test adapters.
No SDK, browser, React, eval, live-console, lab, or provider-experiment entry point is exported. The package remains private in this wave, and no production adapter starts it yet.
Run the complete contract gate with:
pnpm --filter @paperclipai/paperclip-runner check:protocol
Run the Rust runner gate with:
pnpm --filter @paperclipai/paperclip-runner check:runner
This command checks Rust formatting, builds and tests the minimal workspace in
release mode, verifies bounded process cleanup, launches the real
paperclip-runnerd binary through the fake harness, and compares the Rust
conformance and replay summaries with the shared fixtures. The checked-in Cargo
lock and pinned Rust toolchain keep this verification reproducible.
Durability and failure semantics are documented in
runner/DURABLE_TRANSPORT.md. The fault suite
drops a connection before its event ACK, reconnects with the bound lease,
replays the same event, and proves the duplicated command effect ran once.
Codex launch, resume, cancellation, and normalization behavior is documented in
runner/CODEX_PROVIDER.md.
Use generate:protocol-manifest after a schema or fixture change,
generate:protocol-types after a schema change, and
generate:replay-goldens after an intentional reducer change. Commit generated
outputs with their sources; do not edit them by hand.
Use generate:semantic-action-catalog after changing a semantic action
declaration. Its checked-in JSON inventory must land with the source change.
The gate compiles every schema with AJV 2020-12, validates accepted fixtures, rejects unsupported required versions, checks generated TypeScript schema drift, runs the TypeScript contract tests, and compares reducer snapshots and parity summaries byte-for-byte with their checked-in golden files.
