✨ Summary

Fixes #324 — Classic design deadlock after Spec Patch.

After an initial design handoff is completed, any normal Spec Patch in the OpenSpec delta spec permanently blocks the Classic full workflow:

  1. The design guard correctly detects the changed OpenSpec artifacts and instructs the user to run comet handoff <change> design --write.
  2. But the handoff command rejects that exact invocation with ERROR: stale handoff detected — even though --write is the only legal invocation mode (see the usage guard in classic-handoff.ts).

The guard and the handoff command disagree, so the workflow can never leave the Design phase.

Root cause: In domains/comet-classic/classic-handoff.ts, the stale-handoff check rejected any refresh of a completed handoff whose source hash changed, regardless of the explicit --write intent.

Fix: An explicit --write invocation now refreshes the completed handoff instead of failing; non-write invocations keep the original rejection behavior.

🎯 Scope

  • CLI commands (init, status, doctor, update)
  • Core installer / platform detection
  • Comet skills (assets/skills/, assets/skills-zh/)
  • Comet shell scripts (assets/skills/comet/scripts/)
  • Tests / CI
  • Documentation / changelog
  • Other:

🧪 Testing

  • pnpm build
  • pnpm lint
  • pnpm run lint:architecture
  • pnpm format:check
  • pnpm test
  • pnpm test -- test/domains/comet-classic/comet-scripts.test.ts
  • Not run:

Reproduction & verification

Reproduced on master (before the fix):

  • comet handoff <change> design --write succeeds
  • Spec Patch in specs/*/spec.md
  • comet handoff <change> design --write fails with stale handoff detected
  • comet guard <change> design requires the same handoff command → deadlock

After the fix, the same sequence succeeds:

  • [HANDOFF] refreshing stale design handoff: previous hash ...
  • handoff_hash is updated to the current artifacts hash
  • comet guard <change> design passes both handoff checks
  • The refreshed handoff markdown lists the updated source-file SHA256, satisfying designHandoffMarkdownTraceable

✅ Checklist

  • PR title follows Conventional Commits, for example fix: handle project-scope init
  • User-facing behavior is documented in README.md, README-zh.md, or CONTRIBUTING.md
  • CHANGELOG.md is updated when behavior changes
  • Skill changes were made in Chinese first when applicable, then synced to English
  • New scripts are included in assets/manifest.json and relevant tests
  • Shell scripts remain portable across macOS, Linux, and Windows Git Bash
  • No unrelated generated files or local artifacts are included

👀 Notes for Reviewers

  • Bug fix restoring intended behavior: the design guard already instructs users to re-run comet handoff <change> design --write after OpenSpec artifacts change; this PR makes that command succeed again. No README change is needed because this restores the documented flow rather than introducing new behavior.
  • The previous test fails closed when source evidence changed after a completed handoff encoded the deadlock as expected behavior; it now asserts the handoff refreshes successfully and that the refreshed handoff markdown remains traceable by the design guard (updated source-file SHA256 present).
  • format:check and full pnpm test failures are pre-existing on master in the author local Windows environment (symlink/junction-related platform differences; CI runs on ubuntu-latest and passes). The check:generated freshness check and all handoff/runtime/guard/shell-script suites pass locally.

Summary by Sourcery

Restore the Classic workflow by allowing explicit design handoff refreshes after specification changes.

Bug Fixes:

  • Allow completed Classic design handoffs to be refreshed with an explicit write invocation after OpenSpec artifacts change, preventing the design workflow from becoming blocked.
  • Permit design handoff refreshes after the workflow has advanced to the build phase and ensure stale context markdown is regenerated rather than incorrectly treated as current.

Documentation:

  • Document the restored Classic handoff refresh behavior in the changelog.

Tests:

  • Update handoff coverage to verify refreshes after source changes, hash alignment, and phase advancement while preserving source traceability.

Summary by CodeRabbit

  • New Features

    • Classic design handoffs now refresh automatically when source content changes and --write is used.
    • Handoffs can continue through the build phase after design completion.
    • Added validation to ensure generated handoff content matches current source files.
  • Bug Fixes

    • Prevented stale handoff artifacts from being treated as current.
  • Chores

    • Updated the release version to 0.4.0-beta.19 and refreshed related release metadata.

The design guard requires regenerating the handoff when OpenSpec
artifacts change, and 'comet handoff <change> design --write' is the
only legal invocation mode. The stale-handoff check rejected every
such refresh, permanently blocking the Classic workflow at Design.

Explicit --write now refreshes the completed handoff instead of
failing; non-write invocations keep the original guard behavior.

👋 Thanks for opening your first PR to Comet, @baobaolaodie.

Before review, please make sure the PR title follows Conventional Commits, for example fix: handle project-scope init, and that the checklist in the PR template is up to date.

🧪 The most useful local checks are:

pnpm build
pnpm lint
pnpm format:check
pnpm test

🧰 If your change touches assets/skills/comet/scripts/, please also check script portability across macOS, Linux, and Windows Git Bash. Avoid sed -i, support both sha256sum and shasum -a 256, and guard optional grep pipelines with || true.

✨ We appreciate the contribution and will take a look as soon as we can.

Reviewer's Guide

Allow the Classic design handoff command to refresh a completed handoff when OpenSpec artifacts change, adjust the corresponding handoff shell script behavior, update tests to reflect the new behavior, and bump version metadata/docs.

File-Level Changes

Change Details Files
Relax stale-handoff rejection to allow explicit --write refresh of completed Classic design handoffs when evidence changes.
  • Change stale-handoff check to only throw when mode is not --write; otherwise log a warning and proceed to refresh.
  • Preserve existing behavior for non-write modes, still failing fast on mismatched hashes.
  • Document the rationale in comments near the stale-handoff logic.
domains/comet-classic/classic-handoff.ts
Update the comet-handoff shell wrapper to mirror the new refresh semantics and messaging for stale design handoffs.
  • Adjust stale-handoff branch to print a refresh info message and continue when invoked with --write in design mode.
  • Keep the previous error behavior for non-write modes.
  • Ensure output messaging matches the Classic TypeScript runtime behavior for stale handoffs.
assets/skills/comet/scripts/comet-handoff.mjs
Align tests with the refreshed handoff behavior and ensure versioned metadata stays consistent across the repo.
  • Change the stale-handoff test to expect a successful refresh, updated handoff hash, and new log message instead of a failure.
  • Update CLI help and release metadata tests to assert the new 0.4.0-beta.21 version.
  • Bump version strings in package.json, package-lock.json, and assets/manifest.json, and add a CHANGELOG entry describing the handoff fix.

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

Merge Risk: ⚪ Minimal · up to 160ce

This PR lets an explicit --write refresh a completed design handoff after specification changes, preventing the Classic workflow from remaining blocked while preserving rejection for non-write calls. A localized state assertion should be added as test hardening, but no actionable merge-blocking risk remains after normal checks and review.

Please update the versions in package.json and package-lock.json to beta19, and consolidate the changelog entries from versions later than beta18 into beta19; this appears to be a merge error from a previous fix.

At the same time, you need to review the content of the issue again #324 ; a new comment has pointed out a new problem.

Issue rpamis#324 follow-ups from the issue thread:

- A --write invocation no longer reports success while leaving stale
  context files behind when the recorded handoff_hash was aligned to
  the new source hash by hand. The short-circuit now also verifies the
  on-disk markdown lists the current SHA256 of every source file.
- A design handoff can now be regenerated after the guard advanced the
  phase to build, so a later Spec Patch no longer requires a repair-only
  phase escape hatch. The write path only updates handoff context/hash
  and never transitions the run state outside full.design.handoff.
Per maintainer feedback: beta.19 is the intended next release version;
the beta.20 entry was a merge error from a previous fix. Consolidate all
entries newer than beta.18 into a single beta.19 changelog entry.

Please update the versions in package.json and package-lock.json to beta19, and consolidate the changelog entries from versions later than beta18 into beta19; this appears to be a merge error from a previous fix.

At the same time, you need to review the content of the issue again #324; a new comment has pointed out a new problem.

Thanks for the review. Version and changelog are now aligned per your feedback:

  • package.json / package-lock.json / assets/manifest.json and the version-assertion tests now read 0.4.0-beta.19.
  • The changelog entries newer than beta.18 (including the previous beta.20 entry) have been consolidated into a single [0.4.0-beta.19] entry, with the handoff fix added under ### Fixed.

I also reviewed issue #324 again as you asked. The new comment pointed out two follow-on problems, both fixed in this PR:

  1. --write no longer reports success while leaving stale context files behind when the recorded hash was aligned by hand — the short-circuit now verifies the on-disk markdown reflects the current sources.
  2. The design handoff can now be regenerated after the guard has advanced the phase to build, so a later Spec Patch no longer requires the COMET_FORCE_PHASE repair escape hatch.

Both fixes are covered by new tests and verified end-to-end locally.
