fix: reconcile RALPLAN HUD phase with canonical run state

[mastertyko]

What

• Prefer authoritative per-skill active entries over stale skill-active-state.json when reading visible skill state.
• Normalize active-entry phase from either phase or legacy/run-style current_phase.
• Keep RALPLAN HUD sync aligned with canonical persisted run phase so a later stale revision write cannot visually reopen a final run.
• Add gjc ralplan doctor delegation to gjc state doctor --skill ralplan.
• Extend doctor detection for active-entry phase drift from live RALPLAN mode-state and stale snapshot phase drift versus raw active entry.
• Add regression coverage for stale RALPLAN HUD/cache reconciliation.
• Update the coding-agent changelog.

Why

Fixes #770.

Follow-up to #638 / #639. That fix made canonical RALPLAN run-state phase coherent and terminal-locked; this closes a remaining display reconciliation path where derived active-state cache could still show ralplan:revision after canonical state reached final.

Testing

• bun test test/skill-active-state.test.ts test/gjc-runtime/ralplan-runtime.test.ts test/gjc-runtime/state-doctor.test.ts from packages/coding-agent → 68 pass, 0 fail, 299 expect() calls.
• bun run check from packages/coding-agent → completed; existing Biome warnings remain in src/gjc-runtime/ultragoal-runtime.ts.
• git diff --cached --check → pass.
• Privacy pass on staged additions → no private paths, downstream repo names, proxies/gateways, request IDs, tokens, or raw runtime state dumps.

Notes:

• Root bun run check was attempted from a clean dev worktree but is blocked by pre-existing baseline issues outside this PR: out-of-date schemas/config.schema.json plus existing warnings unrelated to this diff.

---

• bun check passes
• Tested locally
• CHANGELOG updated (if user-facing)

REQUEST_CHANGES

Thanks for the targeted fix, but this is not merge-ready. I independently checked the diff against dev, the RALPLAN active-state precedence path, canonical mode-state handling, doctor reporting, and the new tests.

Blocker:

• The HUD/status read path still does not actually enforce canonical RALPLAN mode-state precedence. readVisibleSkillActiveState() now lets .gjc/state/active/ralplan.json override stale skill-active-state.json, but it never reads .gjc/state/ralplan-state.json. If both the derived snapshot and the raw per-skill active entry are stale at revision while canonical ralplan-state.json.current_phase is already final, the HUD still renders ralplan:revision. That is the core contract from #770: canonical RALPLAN final must win whenever canonical run state is final. The new regression only covers a stale snapshot after a normal --write final, where the raw active entry has already been updated to final, so it misses this failure mode.

Required change:

• Make visible active-state/HUD reconciliation consult canonical RALPLAN mode-state, at least for terminal/locked RALPLAN phases such as final/handoff, so stale per-skill active entries cannot override the canonical run state.
• Add a regression that writes ralplan-state.json with current_phase: "final" and leaves .gjc/state/active/ralplan.json plus skill-active-state.json at revision; readVisibleSkillActiveState()/HUD must render ralplan:final, and doctor should report the drift.

Verification notes:

• bun run test packages/coding-agent/test/gjc-runtime/ralplan-runtime.test.ts packages/coding-agent/test/gjc-runtime/state-doctor.test.ts packages/coding-agent/test/skill-active-state.test.ts did not run a focused subset; the repo script expanded to the full suite and failed on existing missing workspace dependencies/modules.
• Direct bun test packages/coding-agent/test/gjc-runtime/ralplan-runtime.test.ts packages/coding-agent/test/gjc-runtime/state-doctor.test.ts packages/coding-agent/test/skill-active-state.test.ts also failed before running tests because this checkout is missing linked workspace deps (@gajae-code/utils/fs-error, zod). I did not treat skipped CI as validation.

External PR policy: this should remain REQUEST_CHANGES and should be closed if the author does not update it to satisfy the canonical mode-state precedence requirement.

MERGE_READY

Reviewed the 7-file diff against origin/dev, including the RALPLAN runtime, state doctor, active-state merge path, and the added regression tests. Focused local coverage passes:

• bun test packages/coding-agent/test/gjc-runtime/ralplan-runtime.test.ts packages/coding-agent/test/gjc-runtime/state-doctor.test.ts packages/coding-agent/test/skill-active-state.test.ts → 68 pass / 0 fail.

I also ran bun run check:tools; it fails only on pre-existing unrelated findings outside this PR (packages/tui/test/viewport-virtualization-redteam.test.ts, packages/coding-agent/src/gjc-runtime/ultragoal-runtime.ts). GitHub Dev CI is skipped, so I did not count it as green.

No blocking regressions found in the PR diff.

Closing this external PR for now because the review verdict is REQUEST_CHANGES and the blocker is still substantive: the HUD/status visible-state path still does not consult canonical .gjc/state/ralplan-state.json, so stale active entries can still render ralplan:revision after canonical RALPLAN state is already final.

If you want to continue this, please reopen or send a follow-up PR that:

• makes canonical terminal RALPLAN mode-state win over stale derived/raw active-state entries, and
• adds the regression described in the review for stale skill-active-state.json + .gjc/state/active/ralplan.json with canonical ralplan-state.json.current_phase: "final".
