## 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 version and `commandDigest` match the current profile exactly. > - #18325 made every provider digest attest its upstream release, and bound the shared ACPX layer and Runner source through the pack `contractDigest`. > - The model is documented, but it lived in prose. A new provider, such as one in an open PR, could still choose another digest model without any check or guidance. > - This pull request makes the model the default path: each provider declares its attestation in one registry, and the generator, a test and a scoped rule explain the pattern where contributors meet it. > - The benefit is that new providers and upstream bumps follow one model, without a growing list of blocked legacy patterns. ## Linked Issues or Issue Description Refs #18325, #18237. **What happened?** After #18325, only Copilot, Grok and Pi went through `acpx-release-attestations.mjs`. Cursor and Antigravity had separate inline checks in the generator, and Claude and Codex had none. A new provider could add a profile with any digest. Nothing told the author how to compute it, and nothing pinned the profile versions that now change only for deliberate resets. **Expected behavior** Every ACPX provider declares how its `commandDigest` attests the upstream release. Tools and review guidance describe the pattern when a contributor adds a provider, bumps an upstream release or changes a version. **Steps to reproduce** 1. Add a new provider profile to `packages/paperclip-runner/acpx-profiles.json` with an arbitrary `commandDigest`. 2. Run `node packages/paperclip-runner/scripts/generate-acpx-profiles.mjs --check`. 3. Before this change, the check passes. ## What Changed - Add `ACPX_RELEASE_ATTESTATIONS` to `scripts/acpx-release-attestations.mjs`. Every profile declares one kind: - `installed-command` (Claude, Codex): installation hashes the upstream launch command. - `launcher` (Grok): the SHA-256 of the launcher shipped verbatim. - `closure` (Copilot, Pi): upstream versions and complete platform closure pins. - `declaration` (Cursor, Antigravity): a checked-in release declaration, as canonical JSON. - `generate-acpx-profiles.mjs` checks every profile through the registry. The separate Cursor and Antigravity digest checks are now part of the same path. No digest changes. - A profile without a declared attestation fails generation. The message says to declare one and points to the rule. - A stale digest message now says that a digest changes only with its upstream release, and that an upstream change keeps the profile version. - Add a test that pins the profile versions. It explains that a bump resets every saved session for that provider, and that a new provider starts at 1. - Add `rules/acpx-profile-identity.mdc`. It describes the identity model, how to add a provider, when to bump a version, and review criteria. `AGENTS.md` and `.greptile/files.json` route the profile, attestation, contract-registry, ACPX driver and provider paths to it. - Update the profile identity section in `packages/paperclip-runner/docs/durable-recovery.md` with the attestation kinds and the version policy. ## Verification - In `packages/paperclip-runner`: - `node scripts/generate-acpx-profiles.mjs --check` passes. Running it without `--check` changes no digest. - `node --test scripts/acpx-release-attestations.test.mjs scripts/contracts/contract-fingerprints.test.mjs`: 22 tests pass. New cases: every profile declares an attestation, a new provider without one fails with guidance, and Cursor and Antigravity declaration changes affect only their own digests. - `vitest run src/drivers/acpx/profile-compatibility.test.ts`: 15 tests pass, including the version table. - `tsc -p tsconfig.json --noEmit` passes. ## Risks - Low risk. No digest, version or runtime admission behavior changes. - A new provider PR must add one registry entry. The generator error states what to add. - The version table needs an edit for each deliberate reset. Upstream bumps do not touch it. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with tool use (shell, file edits, local test runs). ## 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
Repository rules
Keep architectural guidance in focused .mdc files here. Each file is Markdown
with YAML frontmatter containing a description and an alwaysApply boolean.
For scoped rules, set alwaysApply: false and provide comma-separated,
repository-relative globs. For repository-wide rules, set alwaysApply: true
and omit globs. Use ** for all descendants of a directory. Include sibling
entry points explicitly when needed.
Root AGENTS.md tells coding agents to read matching rules before editing or
reviewing code. This directory is a repository convention: Cursor does not
automatically load it as .cursor/rules/, and the .mdc extension alone does not
make a tool apply a rule.
Greptile reads matching rule files through .greptile/files.json and receives
loading instructions from .greptile/rules.md. The rule body remains here as
the single source of truth. Repository configuration takes effect when the
files are available on the reviewed branch; local files alone are not visible
to the hosted reviewer.
When adding or changing a rule:
- State the scope, required behavior, examples, exceptions, and review criteria.
- Add its path to
.greptile/files.json. Copy itsglobsinto that entry'sscopearray, one pattern per element. ForalwaysApply: true, omitscope. - Keep the rule's frontmatter and the Greptile scope synchronized. Verify that the scope covers representative files and excludes unrelated directories.
- Keep detailed policy in the rule file instead of copying it into tool settings.
Product behavior is covered by
product-harness-responsibility.mdc: routine
work belongs to the harness, and user-facing detail must support an outcome or a
real decision. This applies to orchestration as well as UI.
See the Greptile file-reference documentation for the manifest format.
Background execution is covered by
sleep-aware-background-work.mdc: new or
expanded work must become quiet, use events and real scheduler deadlines, and
preserve recovery across transactions, drain, and restart. This rule covers
server/src/index.ts and the worker/producer paths in its scope. It does not
require unrelated legacy polling to be migrated in the same PR.
