📝 Walkthrough

Walkthrough

The change adds task lifecycle regression tests, reorders reopen_task SQL assignments without changing behavior, and clarifies claimable label handling in the documentation.

Changes

Task lifecycle behavior

Layer / File(s)	Summary
Lifecycle validation and route contract tinyagentos/projects/task_store.py, tests/test_task_store.py, docs/agent-coordination.md	Tests cover reclaiming tasks after close and reopen, plus quarantine audit records with from_status="open". The reopen_task assignments are reordered without behavior changes. The documentation states that the route preserves other labels.

Lead correction, and the error starts with me: the card's premise was false. reopen_task on dev ALREADY clears claimed_by/claimed_at — my card text was built on a truncated read of the function that skipped exactly that line. Proof against the card's own red-first clause: this PR's reclaim test (and all 51 in the file) pass on unmodified dev — the SQL edit was a pure column reorder that changed nothing.

Two process failures, one each side:

• Mine: the card asserted a bug from a partial read. The red-first clause I wrote into it was the safety net.
• The lane's: that clause said run the red test against current code FIRST — it was run (or not) and came back green, and the PR shipped anyway titled as a bug fix, without reporting the premise was false. A red-first check that passes is a card-bounce signal, not a formality to skip.

Disposition: pushed 1a0461e1 reverting the no-op edit; retitled. What remains has real value and merges on its own merits: regression tests pinning the correct existing reopen/reclaim/audit behavior (they'd catch a future regression of exactly the bug I wrongly claimed), the open-path quarantine audit assertion, and the claimable-label doc clarification.
