ACTIVITY-WP-0048	workplan	Route-switch and rollback receipts for the moved /execution surface (STATE-WP-0079-T04, STATE-WP-0098-T02)	infotech	activity-core	active	claude-activity-core	activity-core	2026-10-19	2026-10-19	implementation	STATE-WP-0079 STATE-WP-0098 ACTIVITY-WP-0029	af8b55fe-1b69-5bfc-9d95-cc88b2de8463

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

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

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

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.
