+# Event E2E suite (maintainable)
+
+Goal: every catalog event is covered by automation that stays cheap when new ids are added.
+
+## Tracks
+
+| Track | Scenario | What it proves | How new events join |
+|-------|----------|----------------|---------------------|
+| **Inventory audits** | nested in `event_coverage` | Live library vs authored catalog | Add JSON row / live seed; audit fails until matched |
+| **A inject coverage** | `event_inject_coverage` / `ec30` | Every **camera-worthy** id can register an interest key + label | Auto via `EventCatalog.*.AuthoredIds` |
+| **Live outcome** | `event_live_outcome_smoke` | Real API/Beh + `EventOutcome` confirm (curated) | Add a deterministic harness step when a patch exists |
+
+Full suite: `event_suite` = `event_coverage` + `event_live_outcome_smoke`.
+Regression nests `event_suite`.
+
+## Commands
+
+```bash
+./scripts/harness-run.sh event_inject_coverage
+./scripts/harness-run.sh event_live_outcome_smoke
+./scripts/harness-run.sh event_suite
+./scripts/harness-run.sh regression
+```
+
+Artifact: `IdleSpectator/.harness/event-inject-coverage.tsv`
+(`domain`, `id`, `camera`, `result`, `key`, `notes`).
+
+## Design rules
+
+1. **Do not** hand-write one harness step per catalog id for inject - loop `AuthoredIds`.
+2. B-only rows (`CreatesInterest=false`, Ambient happiness) are `skip_b`, not failures.
+3. Inject coverage ≠ live outcome. Inject proves wiring; live proves confirm predicates.
+4. Expand live outcome slowly (family, status apply, happiness apply, …) as wrappers exist.
+5. Libraries: only camera-worthy live-seeded ids are injected (can be large; Signal-gated).
+6. After each successful inject, remove the key from `InterestRegistry`. The registry caps at 96 candidates; leaving them in causes false `register_failed` on later ids.
