 - Each commit holds a list of `SignalEvent`s (time‑ordered by `started_at`).
   Ordering: dicts in Python 3.7+ preserve insertion order. Phase A inserts commit keys in push‑timestamp DESC order, so iterating the mapping yields newest→older commits without extra sorting.
 
+### Test‑track semantics
+- Source of truth for SUCCESS/FAILURE is `default.test_run_s3` per test id.
+- When a test row exists for an attempt:
+  - Emit at most one FAILURE if any failed runs exist; at most one SUCCESS if any successful runs exist.
+- When no test rows exist for an attempt and any grouped job for that attempt is pending → emit PENDING.
+- Otherwise (no test rows and not pending) → no event for that attempt.
+
+### Job‑track semantics (non‑test)
+- Build per normalized job base across commits; aggregate shards by `(wf_run_id, run_attempt)`.
+- Event mapping per attempt uses aggregated job meta with test‑failure filtering:
+  - FAILURE only when the attempt had non‑test failures (e.g. infra‑related).
+  - PENDING when the attempt is still running.
+  - SUCCESS otherwise, including when failures are exclusively test‑caused (these are handled by test‑track).
+- Cancelled attempts are treated as missing (no event).
+- Emit a job‑track Signal only when at least one attempt/commit shows a non‑test (infra) failure within the window.
+
 Event naming (for debuggability):
 - Consistent key=value format: `wf=<workflow> kind=<test|job> id=<test_id|job_base> run=<wf_run_id> attempt=<run_attempt>`
 - Examples:
