New restores every unfinished task in the shared database and runs its planner, worker and deadline loops on the server context. Tests that passed context.Background() never stopped or joined them, so they kept writing under the manager TempDir after the test returned and the TempDir cleanup failed with directory not empty. Add stopTestServer, which cancels the context, waits for each task to go quiescent, joins its loops, the archive worker and the side-question writer, and defer it right after New in every test that started a live server.
TestMgmtAPI never closed its manager, so the notifier and task-archive workers started by New(context.Background()) kept claiming other tests digest batches and archive jobs. TestTaskOutcomeCard left a skill_usage miss row behind (the table has no foreign keys), which outranked TestSkillGapsReport fixture from the fourth -count iteration on.
Adds GET /api/tasks/{id}/outcome: finding disposition and severity,
retest verdicts, result-row token totals, tool calls, skill misses, and
wall time in one row. This is the measurement layer an RSI loop needs
before claiming a change helped; it alters no agent behavior.
Metric selection follows harness2 (Google Research, Apache-2.0,
arXiv 2610.14224) and the task-gain / retained-gain / improver-gain
taxonomy in the awesome-rsi list.
