Implement ACTIVITY-WP-0022/0023: safe sink default and gap closures

Default ISSUE_SINK_TYPE to state-hub (no silent Forgejo issues), hard-fail
prune apply without live-images protection, refresh-live-images script,
disable TaskExecutor stub by default, and document consumer/sink contracts.

-## Promotion and rollback
-
-### Promote one definition safely
-
-1. Keep `ISSUE_SINK_TYPE=null` and run or wait for the target definition.
-2. Review rendered task specs in `task_spawn_log` (source id, condition,
-   target repo, synthetic `null-*` reference).
-3. Confirm `ISSUE_CORE_URL` reachability and a populated `ISSUE_CORE_API_KEY`
-   on both activity-core and issue-core (same value). Credential custody:
-   `warden route show issue-core-ingestion-api-key --json`.
-4. Run the repo smoke:
-   ```bash
-   uv run python scripts/smoke_issue_core_emission.py
-   ISSUE_CORE_URL=http://127.0.0.1:8765 ISSUE_CORE_API_KEY=... \
-     uv run python scripts/smoke_issue_core_emission.py --live
-   ```
-5. Set `ISSUE_SINK_TYPE=rest` in `actcore-runtime-config`, apply
-   `k8s/railiance/15-externalsecret-issue-core.yaml` so External Secrets merges
-   `ISSUE_CORE_API_KEY` into `actcore-runtime-secret`, and restart
-   `actcore-worker` / `actcore-event-router` after the ExternalSecret is Ready.
-6. Trigger one known-safe run (weekly SBOM staleness on a stale fixture or
-   manual `/activity-definitions/<id>/trigger`) and confirm `task_spawn_log`
-   stores the real `issue_id` returned by issue-core.
-
-### Roll back to null-sink
-
-1. Set `ISSUE_SINK_TYPE=null` in `actcore-runtime-config`.
-2. `kubectl -n activity-core rollout restart deploy/actcore-worker deploy/actcore-event-router`
-3. Verify the next run records synthetic `null-*` references again.
-4. Leave issue-core tasks already created in place; activity-core does not own
-   downstream task lifecycle. Close or cancel duplicates in issue-core if a
-   promotion experiment created unexpected tasks.
-
-Duplicate handling today: issue-core REST ingest does not yet dedupe on
-`triggering_event_id`; Temporal retry visibility is the current guardrail.
-Treat promotion as one-definition-at-a-time until server-side idempotency ships.
 
 ## Verification
 
-Local contract tests cover the rendered weekly SBOM task path and the REST
-payload shape:
-
 ```bash
-uv run pytest tests/test_integration_event_bridge.py tests/test_issue_sink.py
+uv run pytest tests/test_issue_sink.py tests/test_integration_event_bridge.py -q
 ```
 
-For a live environment, run with `ISSUE_SINK_TYPE=null` first and confirm
+## Side-effect resolvers (not IssueSink)
-`task_spawn_log` contains the expected source id, condition, triggering event id,
+
-and synthetic task reference. Then switch to `ISSUE_SINK_TYPE=rest` only after a
+`forgejo_package_prune` with `apply: true` is a **declared platform side-effect**,
-single known-safe rule match creates one issue-core task with the same fields.
+not task emission. It requires a non-empty `live_images_file` (ACTIVITY-WP-0023-T03).

+  }
+}
+```
+
+### Required consumer behaviour
+
+1. **Idempotency:** key on `detail.task_ref` or
+   `(activity_definition_id, triggering_event_id, source_id, title)`.
+2. **Routing:** use `target_repo` (and labels) to select checkout / lane.
+3. **Completion evidence:** post a domain progress event when work finishes
+   (e.g. Binky: `event_type=binky_daily_brief` with `detail.repo=binky-control`
+   and date), so rhythm resolvers can set `due=false`.
+4. **Do not** re-implement task lifecycle in activity-core.
+
+## Payload: issue-core REST (`ISSUE_SINK_TYPE=rest`)
+
+See `docs/issue-core-emission-boundary.md`. `task_spawn_log.task_ref` is the
+issue-core `issue_id`. Prefer this only for intentional external projection.
+
+## Binky daily brief path (reference)
+
+1. Schedule / one-shot: `Binky Daily Operating Rhythm`.
+2. Context: `binky_rhythm_status` → `due=true` for `daily_brief`.
+3. Rule emit → sink (`state-hub` recommended).
+4. **Consumer (out of repo):** agent-harness or operator session runs
+   `binky-control` OperatingRhythm / brief scripts.
+5. Completion: post `binky_daily_brief` progress so the next fire is not due.
+
+Until a harness consumer is wired, operators may complete the brief manually
+and still post the progress event — spawn without completion leaves `due=true`.
+
+## Anti-patterns
+
+- Using `TaskExecutorWorkflow` in activity-core for real work (disabled by
+  default; ACTIVITY-WP-0023-T08).
+- Global `ISSUE_SINK_TYPE=rest` for all definitions (reintroduces Forgejo spam).
+- Treating `task_spawn_log` as task status authority.
