Nicky LeachandClaude Opus 5.5 abc270ee4c fix(runner): attest upstream releases and bind ACPX uniformly for every harness (#18325)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native ACPX runs admit a provider only when its saved profile and
`commandDigest` match the current profile exactly.
> - For Copilot, Grok and Pi, `commandDigest` hashed dozens of Paperclip
source files. Claude, Codex, Cursor and Antigravity hash only their
upstream release.
> - Any change to a bound source therefore advanced these profiles.
#18212 alone moved Copilot from v88 to v91 and Grok from v15 to v19.
Each bump reset in-flight sessions and added immutable identity fixtures
(about 160 on master).
> - #18237 added the provider pack `contractDigest`, which now guards
Runner source compatibility at the pack boundary.
> - This pull request changes the Copilot, Grok and Pi digests to
upstream release attestations, as the other providers already use.
> - It also binds the shared ACPX layer the same way for every ACPX
harness: the profile's `acpxVersion` and the pack `contractDigest`,
which now covers the Runner's ACPX patch.
> - The benefit is that Runner source changes no longer reset these
sessions or need new profile versions and fixtures.

## Linked Issues or Issue Description

Refs #18237, #18212, #17972.

**What happened?**

A Runner change that touched a bound source file changed the Copilot,
Grok or Pi `commandDigest`. The author had to advance the profile
version, regenerate an identity fixture and keep every old fixture. On
deploy, saved sessions for that provider failed the exact admission
check and started fresh.

**Expected behavior**

A provider's `commandDigest` changes only when its upstream release
changes: an upstream version, a platform closure, the ACPX patch or the
Grok launcher. Runner source compatibility is the job of the pack
`contractDigest`.

**Steps to reproduce**

1. On master, change a comment in `src/drivers/acpx/runtime-host.ts`.
2. Run `node packages/paperclip-runner/scripts/grok-profile-identity.mjs
--check`.
3. The check fails. The Grok profile must advance, and the next deploy
resets Grok sessions.

## What Changed

- Add `packages/paperclip-runner/scripts/acpx-release-attestations.mjs`.
It computes the release attestation for each provider:
- Copilot and Pi: a canonical-JSON hash of the profile version, upstream
package versions and the platform closure pins (Pi also binds its Node
version).
- Grok: the SHA-256 of `launcher.cjs`. Admission already hashes these
bytes.
- The attestation binds no Paperclip source, shared ACPX layer, absolute
path, pack manifest digest or install layout.
- Bind the shared ACPX layer once for every ACPX harness (Claude, Codex,
Copilot, Cursor, Grok, Pi, Antigravity):
- Add the Runner's ACPX patch (`patches/acpx@<runner acpx
version>.patch`) to the pack `contractDigest`. A patch change now
retires older image packs for every harness. Other packages' ACPX
patches are not read. A build context without the Runner's patch fails.
- Remove the ACPX patch hash from Cursor's release declaration
(`cursor-contract.json`) and advance Cursor once to profile 17. Copilot,
Pi and Cursor no longer bind ACPX in their own digests, like Claude,
Codex, Grok and Antigravity.
- Saved inputs for every harness already must match the current
`acpxVersion`.
  - Claude and Codex digests do not change.
- `generate-acpx-profiles.mjs` writes these digests to
`acpx-profiles.json`. `check:acpx-profiles` refuses a stale digest.
- Move the Copilot closure pins to `copilot-closure-pins.ts`, so that
the generator can import them. `copilot-installation.ts` re-exports
them.
- Advance each profile once and then freeze it: Copilot 92, Grok 20, Pi
37. A version change at the switch keeps the rollout on the same path as
every earlier profile bump.
- Replace the historical version lists in `profile-compatibility.ts`
with a range. Every revision from 1 through the current one decodes.
Claude and Codex still decode revisions 1 through 5. Launch and recovery
admission still require the exact current profile and digest.
- Delete:
- `scripts/copilot-profile-identity.mjs`,
`scripts/grok-profile-identity.mjs` and its test
  - the Grok launcher source stamp
- 159 Copilot, Grok and Pi identity fixtures, including three
unreferenced `copilot-mainline-v*` fixtures. The Cursor fixtures stay.
- Rewrite the affected tests as behaviour checks:
- Each provider admits only the exact current profile. Every earlier
version decodes and is refused at admission.
- The last source-bound digests, and a changed digest at the current
version, are refused by recovery and by the backend factory.
- The Rust Pi descriptor test uses the generated profile instead of
fixtures.
- New `acpx-release-attestations.test.mjs`: a relocated copy of the
inputs gives the same digests, each upstream input changes only its own
providers, and the generator refreshes and checks the manifest.
- Remove the fixture exceptions from `.dockerignore`. Add the
attestation script and the generator to the Daytona image content
inputs.
- Update the Pi install probe and the Rust integration constant for the
new Pi digest.
- Update the docs to describe the current attestation model:
`doc/grok-native-runner.md`, `doc/RUNNER-INTEGRATION-PLAYBOOK.md`,
`doc/observability.md`,
`packages/paperclip-runner/docs/durable-recovery.md`, and the Copilot,
Pi and rich ACP architecture reports. Each report now opens with the
current profile identity; earlier source-bound profiles remain as dated
chronology. No doc references a deleted file.

## Verification

- In `packages/paperclip-runner`:
- `node --test scripts/acpx-release-attestations.test.mjs
scripts/contracts/contract-fingerprints.test.mjs`: 19 tests pass,
including a Runner ACPX patch edit that changes the contract digest,
other patch edits (including `acpx@0.12.0` for `adapter-utils`) that do
not, and a build context without the patch that fails.
  - `node scripts/generate-acpx-profiles.mjs --check` passes.
- `vitest run src/drivers/acpx src/backends src/contracts`: 1647 tests
pass, 9 skipped.
  - `tsc -p tsconfig.json --noEmit` passes.
- From the repository root, `vitest run --config
tests/runner-e2e/vitest.config.ts
tests/runner-e2e/daytona-image.test.ts`: 11 tests pass.
- In `server`, the 8 test files that use ACPX profiles, pack digests or
`contractDigest`: 1617 tests pass.
- Not run locally: the Rust tests and `cargo fmt`, because this machine
has no Rust toolchain. CI runs them.
- Before this change, a synthetic upgrade check built two Runner
revisions that differ only in shared source. A Claude checkpoint saved
under the first revision rebinds under the second, and a changed Claude
`commandDigest` starts fresh. This confirms that the provider JSON has
no other build-dependent field.

## Risks

- **One reset at rollout.** The Copilot, Grok, Pi and Cursor digests and
versions change once. Saved sessions for these providers start fresh on
their next run, as after any earlier profile bump. After this change,
Runner source changes no longer cause this reset.
- **Lost "source changed, so requalify" signal.** The old digest forced
a new profile version when bound source changed. Nothing enforced
requalification: Copilot was last qualified at v47. Pack-boundary
contract changes are now caught by the pack `contractDigest`.
- **Image packs are retired once for every provider.** Adding the ACPX
patch changes the pack `contractDigest`, so the controller uploads its
bundled pack (about 16 s per remote start) until images are refreshed.
Claude and Codex sessions are not reset: their digests and versions do
not change.
- **Grok launcher and closure pins.** The Grok digest covers only the
launcher bytes. Grok's runtime version is still checked separately at
admission, as before.
- **Grok digest equals early Grok profiles.** The launcher bytes have
not changed since profile 1, so the new Grok digest equals the published
profile 1 digest. The profile version still separates them: launch,
recovery and the backend factory require profile 20. An image pack from
that period has no `contractDigest`, so the pack gate refuses it.
`remote-provider-pack-verification.test.ts` now covers this case.
- **Docker context checks** run `generate-acpx-profiles.mjs --check`,
which now imports `.ts` pin files through Node type stripping.
`materialize-pi-distribution.mjs` already relies on this on Node 24.

Nicky LeachandClaude Opus 5.5 fa760dbce4 fix(runner): reuse image packs only with matching contract digest (#18237)
## 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.
