## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Remote native runs use a provider pack. The controller reuses a protected pack from the sandbox image when the pack is compatible. > - #17749 gates this reuse on a hand-maintained interface revision in `provider-pack-contract.json`. > - Later changes altered the runner/pack boundary (#17922, #18188), but nobody bumped the revision. A stale Claude or Codex image pack can still be reused across a sidecar contract change. This is the failure class of #17972. > - A manual revision has a "forgot to bump" failure mode. Source-byte hashes change on every refactor, so they are too brittle. > - This pull request declares the sidecar `session.open` contract in its JSON schema and computes a contract digest from the JSON contracts and Rust shapes. > - Image-pack reuse now requires an equal digest. > - The benefit is that an incidental change keeps image packs reusable, and a real contract change retires them automatically. ## Linked Issues or Issue Description Refs #17749, #17972, #17922, #18188. **What happened?** The controller reused an image provider pack when `compatibility.acpx` and the selected agent's profile digest matched. For Claude and Codex, that profile digest binds only the upstream executable. The ACPX interface revision stayed at 1 after later sidecar contract changes. A pack built before those changes passed the reuse check. **Expected behavior** The controller reuses an image pack only when the pack uses the same runner/pack contracts as the controller's bundled pack. Comments, formatting and refactors do not change that result. **Steps to reproduce** 1. Build an image pack from a commit before a sidecar input change, such as a new `session.open` field. 2. Run a controller from a later commit that sends the new field, with the same interface revision and Claude version. 3. Before this fix, `verifyRemoteProviderPack` accepts the old image pack. ## What Changed - Declare the sidecar `session.open` parameter set as a closed `sessionOpenParams` definition in `acpx-sidecar.schema.json`. - `generate-acpx-sidecar-contract.mjs` now generates `GENERATED_ACPX_SIDECAR_OPEN_PARAMS` from it. - `parseOpenParams` uses the generated list instead of an inline `Set`. The accepted set is unchanged. - This is the surface of #17972. The schema is now its source of truth. - Declare the nested `session.open` contracts that the sidecar parses strictly: - `protocol/provider-schemas/runtime-context.schema.json` closes every runtime context object. `parseNativeRuntimeContext` uses the field lists that `scripts/generate-runtime-context-contract.mjs` generates from it. - The sidecar schema declares the closed `providerPolicy` object, and `parseProviderPolicy` uses its generated field list. - The accepted fields do not change. - Add `packages/paperclip-runner/scripts/contracts/contract-fingerprints.mjs`. It fingerprints these contracts: - the PRP and sidecar JSON schemas, with annotation text removed - the generated catalogs in `generated/` - the Rust serde shapes, `json!` payload keys, match literals and env keys in `runner-core/src`, without test-only modules - the reserved env key lists in `configured_environment.rs` - Read only the trees that every pack build context contains. Fail when a registered source is missing, so two build contexts cannot silently produce different digests. - Use only Node built-ins. The registry adds no dependency. - Write `contractDigest` as a top-level payload field in `build-provider-pack.mjs`. The manifest digest algorithm and the existing field layout do not change. - Require an equal `contractDigest` for image-pack reuse in `remote-provider-pack-verification.ts`. A pack without a digest is not reused. The controller uploads its bundled pack, as it does today for any incompatible pack. - Re-attest the source-hashed profiles, because this PR changes their bound sidecar sources: - Grok becomes profile 15 and now also binds the generated allowlist, so a Grok field change in the schema still invalidates the Grok identity. - Copilot becomes profile 88, and also binds the generated runtime context fields. - Earlier profiles stay decodable. - Add the registry script and `generated/` to the Daytona image content inputs. - Document the digest and the schema-first rule in `docker/daytona-runner/README.md` and `doc/DEVELOPING.md`. ## Verification - `node --test scripts/contracts/contract-fingerprints.test.mjs` (in `packages/paperclip-runner`): 4 tests pass. - These changes keep the digest: - schema description text - schema reformatting - renaming `parseOpenParams` - Rust comments, `#[serde(skip)]` fields and `#[cfg(test)]` modules - edits to the `#[path]` test module `tests/provider_api_validation.rs` - These changes alter the digest: - a new `session.open` schema field - a changed constraint on the `remainingWork[].description` property - a new reserved env key - a new sidecar env key - a new checkpoint field - A build context without a registered source fails. - `node --test test/acpx-sidecar-contract.test.mjs`: 13 tests pass. A new case rejects an unknown `session.open` parameter and accepts each declared parameter. - `node --test scripts/grok-profile-identity.test.mjs`: 4 tests pass. A change to the Grok field in the generated allowlist invalidates the Grok identity. - `generate-acpx-profiles.mjs --check`, `generate-acpx-sidecar-contract.mjs --check` and `generate-protocol-manifest.mjs --check` pass. - Runner vitest suites pass: 470 passed, 1 skipped. They cover the sidecar, sidecar input and protocol, Copilot and Pi installation, profile compatibility, native execution, recovery identity, the backend factory and the environment. - Server tests: pack verification, executor and artifact preparation pass (1,004 tests). - `tsc --noEmit` passes for `packages/paperclip-runner` and `server`. - `tests/runner-e2e/daytona-image.test.ts`: 10 of 11 tests pass. The failing test also fails on `master`. It expects a literal `profile-v19-identity.json` line in `.dockerignore`, which uses a `profile-v*` glob. - Not run locally: - A complete `build-provider-pack.mjs` run. The builder rejects the local Homebrew Node because it is not portable after relocation. - Rust tests and `acpx-controller-recovery.test.ts`, because `cargo` is not installed. - The full `pnpm -r typecheck`, `pnpm test:run` and `pnpm build`. ## Risks - Only JSON contracts and Rust shapes are part of the digest. The remaining TypeScript-only definitions are the `paperclip_finish` and `paperclip_block` tool schemas in `completion-result.ts` and the TypeScript env key lists. They are not covered until they move into a schema. The nested `expectedIdentity` and `tools` values ignore unknown fields, so a change there cannot cause a startup rejection. - A change there can let a stale image pack be reused. The sidecar then rejects the input with its strict parser error. - Today, Claude and Codex image packs have no contract check at all. - The digest covers all registered contracts for the whole pack. A contract change for one provider kind also retires image packs for the other. Each replacement costs about 16 s per remote start until the image is refreshed. - Existing image packs have no digest. After deploy, the controller uploads its bundled pack until the image is rebuilt. - The Grok and Copilot re-attestations start fresh sessions for those agents once after deploy, as each profile bump does today. - The Daytona image content ID formula changes, so the next image build does not reuse a cached image. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
