Origin: State Hub messages 4427c6cb (STATE-WP-0079-T04 asks for the workplan
that holds activity-core's receipts) and 13cff5ff (STATE-WP-0098-T02 asks about
the `/workplan-queue` dashboard view), both dated 2026-10-13.

Scope is only the part activity-core owns. That part is `GET /execution/semantics`,
plus `GET /ops-runs` as the automation-history replacement for
`GET /execution/launch-requests`. `GET /execution/workplan-stack` and
`PATCH /execution/workplans/{id}/intent` are not activity-core's. The first
belongs to the Repo Manager work index or the hub-core projection; for the
second, edit the workplan file. activity-core's own `/execution` routes answer
410 with those pointers (ACTIVITY-WP-0029). `POST /execution/launch-requests`
does not move: workplan ids are never queued in activity-core.

## Candidate read smoke

```task
id: ACTIVITY-WP-0048-T01
status: todo
priority: medium
state_hub_task_id: "92d0af6a-217e-5382-9803-1dc9d90e48a6"
```

Run a read-only smoke against the production activity-core API.
`GET /execution/semantics` returns 200 with the `replacements` map, and the
State Hub 410 routes point to the same owners. `GET /ops-runs?limit=50`
returns rows comparable on ids and counts with what the dashboard used
`GET /execution/launch-requests` for. Record the commands and the result
here. There are no writes.

## Route-switch receipt

```task
id: ACTIVITY-WP-0048-T02
status: wait
blocked_on: message-from:state-hub
priority: medium
state_hub_task_id: "02358c93-627a-5dcb-abbf-922a9ebf2263"
```

Wait: State Hub sets the switch window and gives metered acceptance under
STATE-WP-0079-T04. The `/workplan-queue` page points its `/execution/semantics`
read and its history read at activity-core behind a toggle. The other
widgets go to repo-manager or hub-core. Record the switch time, the toggle
state and the smoke result as the receipt.

## Rollback receipt

```task
id: ACTIVITY-WP-0048-T03
status: wait
blocked_on: message-from:state-hub
priority: medium
state_hub_task_id: "16a55060-8362-5667-ad43-a43bf2e82294"
```

Rollback flips the toggle back to the retained State Hub view, which stays
unchanged. Rehearse it once in the switch window and record the receipt.
