+# ActivityDefinition: Hourly RecentlyOnScope Reports
+
+## Purpose
+
+This definition is the activity-core handoff point for
+`CUST-WP-0046 - Activity-Core Hourly RecentlyOnScope Reports`.
+
+It schedules a deterministic State Hub batch run that generates
+RecentlyOnScope reports for every active domain with qualifying activity in the
+last hour. State Hub owns active-domain selection and report rendering;
+activity-core owns the hourly schedule and ActivityRun audit trail.
+
+## Runner Status
+
+This definition is intentionally `enabled: false` until the manual canary
+passes.
+
+Cutover boundary:
+
+- Codex app automation remains a fallback until `CUST-WP-0046-T06`.
+- This activity-core definition becomes the primary hourly reporting substrate
+  only after one manual run and one scheduled run leave expected evidence.
+- Do not run a Codex fallback and this activity-core hourly routine as parallel
+  primary runners.
+
+## Trigger
+
+Hourly at minute 0 in `Europe/Berlin`, with `misfire_policy: skip`.
+
+If the activity-core host is offline at the top of the hour, this routine
+skips the missed run rather than replaying a burst of stale reports after the
+host returns.
+
+## Deterministic State Hub Invocation
+
+The `recently_on_scope_hourly` State Hub context resolver issues:
+
+- `POST /recently-on-scope/hourly`
+- payload: `{"range": "1h", "active_only": true, "include_attention": false}`
+
+The context source is marked `required: true`. A failed State Hub call fails
+the activity-core workflow visibly instead of silently binding an empty
+context. On success, the response is stored in the ActivityRun
+`context_snapshot` under `recently_on_scope_hourly`.
+
+State Hub also records a compact progress event with event type
+`recently_on_scope_hourly`, including generated, skipped, and failed domain
+metadata.
+
+## Output Contract
+
+The run should produce:
+
+- one State Hub progress event with `event_type: recently_on_scope_hourly`
+- one report file per active domain with qualifying activity
+- no report for inactive or quiet domains unless State Hub is explicitly
+  configured otherwise
+- one activity-core ActivityRun containing the batch response metadata
+- no LLM call and no direct workplan or canon edits

+# Hourly RecentlyOnScope Runbook
+
+## Purpose
+
+This runbook answers whether the hourly RecentlyOnScope routine ran without
+opening Codex Desktop.
+
+The intended steady state is:
+
+- activity-core owns the hourly schedule and ActivityRun audit trail.
+- State Hub owns active-domain selection, report generation, report storage,
+  and the `recently_on_scope_hourly` progress event.
+- Codex app automation is not part of the primary hourly reporting path after
+  `CUST-WP-0046-T06`.
+
+## Schedule Check
+
+From the activity-core host, confirm the definition is synced and the Temporal
+schedule exists:
+
+```bash
+cd ~/activity-core
+ACTIVITY_DEFINITION_DIRS=/home/worsch/the-custodian make sync-activity-definitions
+make sync-schedules
+```
+
+Expected definition:
+
+- name: `Hourly RecentlyOnScope Reports`
+- trigger: `0 * * * *`
+- timezone: `Europe/Berlin`
+- misfire policy: `skip`
+- enabled: `false` until manual canary passes, then `true`
+
+## Temporal Check
+
+Use the Temporal UI or CLI on the activity-core host to inspect schedules and
+recent workflows.
+
+Look for:
+
+- a schedule for `Hourly RecentlyOnScope Reports`
+- the most recent `RunActivityWorkflow`
+- a successful workflow result with `tasks_spawned: 0`
+
+A failure in the required State Hub context source should fail the workflow
+visibly rather than recording an empty context.
+
+## ActivityRun Check
+
+Query the activity-core database for the most recent run of the hourly
+definition:
+
+```sql
+select
+  run_id,
+  fired_at,
+  scheduled_for,
+  context_snapshot->'recently_on_scope_hourly' as batch_result
+from activity_runs
+where activity_id = 'd104348c-d792-4377-943c-70a31e81a9bc'
+order by fired_at desc
+limit 5;
+```
+
+The `batch_result` should include `generated`, `skipped`, `failed`, and
+`progress_event_id`.
+
+## State Hub Progress Check
+
+Ask State Hub for the latest batch progress events:
+
+```bash
+curl -s "http://127.0.0.1:8000/progress/?event_type=recently_on_scope_hourly&limit=5" \
+  | python3 -m json.tool
+```
+
+Expected:
+
+- `event_type`: `recently_on_scope_hourly`
+- `author`: `state-hub`
+- `detail.generated`: domains with qualifying activity
+- `detail.skipped`: quiet active domains
+- `detail.failed`: empty in the healthy case
+
+## Report Check
+
+List reports for a domain:
+
+```bash
+curl -s "http://127.0.0.1:8000/domains/custodian/recently-on-scope/" \
+  | python3 -m json.tool
+```
+
+Read a report:
+
+```bash
+curl -s "http://127.0.0.1:8000/domains/custodian/recently-on-scope/<report_id>"
+```
+
+Default report directory:
+
+```text
+~/state-hub/reports/recently-on-scope/<domain_slug>/
+```
+
+## Manual Batch Canary
+
+Before enabling the hourly schedule, run:
+
+```bash
+curl -s -X POST "http://127.0.0.1:8000/recently-on-scope/hourly" \
+  -H "Content-Type: application/json" \
+  -d '{"range":"1h","active_only":true,"include_attention":false}' \
+  | python3 -m json.tool
+```
+
+Then trigger the activity-core path with the same payload and confirm an
+ActivityRun captures the batch response under `recently_on_scope_hourly`.
+
+## Offline Behavior
+
+The schedule uses `misfire_policy: skip`.
+
+If the activity-core host is offline at the top of the hour, that hourly run is
+missed. When the host returns, activity-core should resume with the next hourly
+slot rather than replaying stale runs in a burst.
+
+## Retention
+
+State Hub currently writes one Markdown report per domain and report id. Report
+ids are deterministic for exact windows and are replaced on rerun. The current
+implementation does not delete old reports automatically.
+
+Until a retention job exists, operators should treat the report directory as an
+append-only operational record and prune only after confirming that no audit or
+handoff references point at the target files.

+## Implementation Evidence - 2026-05-22
+
+Implemented pieces:
+
+- State Hub now exposes `POST /recently-on-scope/hourly`.
+- State Hub batch generation reuses the existing RecentlyOnScope collector,
+  renderer, report id, and report directory.
+- The batch endpoint selects domains by qualifying activity in the requested
+  window: progress events, decisions, updated workstreams, or updated tasks.
+- Domains with only registered repositories are skipped; domains with open
+  human-intervention items can be included by setting `include_attention: true`.
+- The batch endpoint records one `recently_on_scope_hourly` progress event with
+  generated, skipped, and failed domain metadata.
+- activity-core has a reusable State Hub resolver query
+  `recently_on_scope_hourly` that POSTs to the batch endpoint.
+- activity-core context sources can now be marked `required: true`; required
+  resolver failures fail the workflow instead of silently binding `{}`.
+- Custodian now owns
+  `activity-definitions/hourly-recently-on-scope.md`, disabled until canary.
+- Operator verification notes live in
+  `docs/hourly-recently-on-scope-runbook.md`.
+
+Verification:
+
+- State Hub:
+  `/home/worsch/.local/bin/uv run pytest tests/test_recently_on_scope.py`
+  passed with 11 tests.
+- State Hub:
+  `/home/worsch/.local/bin/uv run pytest tests/test_recently_on_scope.py tests/test_mcp_smoke.py::TestAddProgressEvent`
+  passed with 14 tests.
+- activity-core:
+  `/home/worsch/.local/bin/uv run pytest tests/test_state_hub_context_resolver.py tests/test_sync_activity_definitions.py tests/test_schedule_lifecycle.py`
+  passed with 19 tests.
+- activity-core parser scan with
+  `ACTIVITY_DEFINITION_DIRS=/home/worsch/the-custodian` found
+  `Hourly RecentlyOnScope Reports`.
+
+Local canary evidence:
+
+- Direct State Hub batch canary generated reports for `custodian` and
+  `markitect`, skipped 9 quiet active domains, and had no failed domains.
+  Progress event: `ff1e845f-df02-476e-a3f3-fb912e4f32a8`.
+- Direct activity-core resolver canary invoked the same State Hub batch endpoint
+  and generated reports for `custodian` and `markitect`, skipped 9 domains, and
+  had no failed domains.
+  Progress event: `1ff091c3-227c-4a85-b5e2-172ba45a2676`.
+
+Remaining gates:
+
+- T01 remains in progress until the deployed activity-core API/worker/Temporal
+  schedule path is checked from the operator host.
+- T04 remains in progress until the definition is synced into the live
+  activity-core DB and appears as a disabled/paused Temporal schedule.
+- T05 remains in progress until a real `RunActivityWorkflow` produces an
+  ActivityRun and one scheduled hourly canary completes.
+- T06 is blocked until T05 passes; the Codex app fallback should not be paused
+  or deleted before then.
+
 ## Acceptance Criteria
 
 - Hourly RecentlyOnScope reports are generated by activity-core, not Codex app
