fix(release): retain ACP load response semantics by Microck · Pull Request #18 · Microck/t3code

Microck · 2026-11-05T03:15:46Z

Problem

Personal release run 41957599592 stopped before publication: conflict resolution restored upstream's replay-idle race, making session loading succeed before its actual response. Two carried regression tests caught the behavior.

Change

After carried patches apply, normalize the exact known conflict shape to await the real session/load response while preserving candidate configuration. Fail closed on unexpected shapes. Already-correct sources remain unchanged. No release gate or test is removed.

Verification

Three focused Node tests pass locally, including unexpected-shape rejection. On the failed prepared snapshot with only the corresponding runtime change, the full ACP connection and runtime-model tests plus server typecheck passed in QA run 41960286910. Full PR checks, review and an end-to-end release remain pending.

Scope

A focused repair for the observed release regression, covered by the user's standing personal fork maintenance authorization.

@coderabbitai review Please review current head 63e769c, particularly the fail-closed ACP session-load normalization, idempotence, preservation of candidate configuration, and release test coverage.

coderabbitai · 2026-11-05T03:44:48Z

@Microck I’ll review head 63e769c, with particular attention to:

Fail-closed ACP session-load normalization.
Idempotence.
Preservation of candidate configuration.
Release test coverage.

## Ownership boundaries

### Pull request linking compatibility

Provider-specific behavior belongs behind an adapter. Orchestration works with normalized commands
and events, so adding a provider should not require branches throughout the domain or clients.
See [provider constraints](./providers.md).

Walkthrough

Release preparation now normalizes ACP session load source. The workflow runs Node.js tests for recognized legacy and unexpected source shapes.

Changes: ACP load compatibility

Layer / File(s)	Summary
Normalize and test ACP load source `scripts/personal-release-load.ts`, `scripts/personal-release-load.node-check.ts`, `.github/workflows/personal-release.yml`	`normalizeLoadResponse` removes the recognized replay-idle race and rejects unexpected source shapes. Tests cover normalization, unchanged input, idempotence, and rejected shapes. The workflow runs these tests.
Apply normalization during release preparation `scripts/personal-release.ts`	Release preparation normalizes `AcpSessionRuntime.ts`. It writes, stages, and commits the file only when normalization changes the source.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Full details: Title check

Explanation

The title "fix(release): retain ACP load response semantics" matches the main change: the PR normalizes the ACP session-load conflict shape so session/load awaits the real RPC response instead of the replay-idle race. It follows conventional commit form and is specific enough for a teammate scanning history.

Full details: Description check

Explanation

The description follows the template's Problem, Change, and Verification sections, and it describes the regression, the normalization fix, and the tests run. It does not include a Scope and approval section that links a triaged issue or maintainer-approved discussion. It gives only a short authorization note (a standing personal fork maintenance authorization) and does not link an approval comment or explain why the fix qualifies without a prior issue. The Verification section names focused tests and a QA run, and it states what remains pending. The description is mostly complete, but the scope requirement is only partly met.

Resolution

Add a Scope and approval link. Link the triaged bug issue or the discussion with explicit maintainer approval, including the approval comment. If no issue exists, explain why this very small, focused fix of an obvious bug qualifies without one. Explain how the standing personal fork maintenance authorization covers this change, and cite where that authorization is recorded.

@Microck I’ll review final head 7c8c03d, including the runtime helper copy and isolated import smoke check, and report any remaining findings. I’ll also check fail-closed normalization, idempotence, preservation of candidate configuration, and release test coverage.
