# State Hub retirement strangler and disposition execution

## Goal

Execute the **keep/move/replace/retire** dispositions from
`prj-state-hub-retirement/inventory` via strangler adapters and owner handoffs,
without adding new permanent authorities here. End state: freeze window with no
normal traffic, then archive.

## Dual-run handoff (RMGR-WP-0002)

Repo Manager Stage B dual-run is available:

- Flags: `RM_WRITEBACK`, `RM_RECONCILE`, `RM_PILOT_REPOS` (see `repo-manager/docs/dual-run.md`)
- SH adapter: `api/services/repo_manager_dual_run.py` (PATCH `/tasks` + C-15 writeback + reconcile proxy)
- Evidence: `repo-manager/docs/evidence/wp0002-completion.md`

Expand pilot list here as cutover progresses; do not add new checkout mutators in State Hub.

## Freeze policy for new scope

```task
id: STATE-WP-0079-T01
status: todo
priority: high
state_hub_task_id: "375c0b66-98b0-4d5b-98dd-4ad2883a4051"
```

Document and enforce: changes during retirement must preserve compatibility,
enable extraction, reduce scope, or fix operational risk — not establish new
permanent ownership (INTENT retirement status).

## Capability strangler plan

```task
id: STATE-WP-0079-T02
status: done
priority: high
state_hub_task_id: "595c3936-20b6-453f-92b5-84f86798054a"
```

Group SHR-INV-0001 items into cutover slices (repo/work → repo-manager;
messages/progress/projections → hub-core; catalogs → owners; retire aliases).
Per slice: adapter flag, owner API, rollback.

**Result (2026-08-19):** `docs/retirement-cutover-slice-plan.md`. All 425
inventory items assigned to 19 slices in five waves plus Keep, computed against
`state-hub-disposition.yaml` rather than hand-counted. Each slice carries an
`RM_SLICE_*` flag (off/dual/owner), owner API, and rollback; Wave A reuses the
RMGR-WP-0002/0003 dual-run adapter rather than adding a mechanism.

Owner readiness verified: only **Wave A (repo-manager, 165 items)** is
executable — RMGR-WP-0001/0002/0003 are `finished`. Wave B is gated on
HUB-WP-0004 (`proposed`), D1 on OPS-WP-0003 (`proposed`), D2 on FIN-WP-0003
(`proposed`). Recommended first cut is A3 (registers), lowest blast radius.

Two findings for T04/T05: the 9 `ops_dependency` items carry no capability and
cannot be strangled behind a flag — they resolve at the T06 freeze window; and
the legacy-meter review window is 8 hours despite `cadence: weekly`, which is
not sufficient evidence to retire high-volume `/workstreams/` interfaces (E2).

## Register CLI and GOAL.md support

```task
id: STATE-WP-0079-T03
status: done
priority: medium
state_hub_task_id: "55716f12-fb12-4a1e-a770-076c490db111"
```

Adapt `statehub register` / scaffolding so `prj-` repos with `GOAL.md` and
`repo_flavor: project` are valid without inventing durable-product `INTENT.md`
(residual from SHR-WP-0001-T01).

**Result (2026-08-19):** Implemented by `STATE-WP-0080-T01/T02`. Project
flavor is detected from classification, `GOAL.md`, or the `prj-` slug; a repo
with an existing `GOAL.md` is registered without durable scaffolding, while a
fresh project delegates scaffolding to `rmgr scaffold`. The focused State Hub
registration suite passes (`20 passed`).

## Execute move/replace slices

```task
id: STATE-WP-0079-T04
status: todo
priority: high
state_hub_task_id: "db5291f2-3801-40fa-abf2-ceb0e77687c9"
```

Implement strangler handoffs coordinated with RMGR-WP-0001 and HUB-WP-0004.
Compatibility tests for each dispositioned route family.

**Inherited (2026-08-19) from `STATE-WP-0080-T04`:** this slice now also owns
deletion of the templating path in `statehub_register.py` — `INTENT.md`
generation, the `AGENTS.md` / `CLAUDE.md` / `.custodian-brief.md` templates,
`project_rules/`, and bootstrap-workplan generation. The code is dead-but-present:
project repos are already routed to `rmgr scaffold`. Gate the deletion on
`RMGR-WP-0004-T06` proving byte-identical durable output and idempotent
re-scaffolding.

## Retire legacy surfaces

```task
id: STATE-WP-0079-T05
status: todo
priority: medium
state_hub_task_id: "02e508ed-3cde-4487-907e-d324a8a877d6"
```

Complete retirement of suggestions, workstream aliases, and other `retire`
inventory items once meters/callers allow. Keep historical rows archive-readable.

## Stabilization window and archive prep

```task
id: STATE-WP-0079-T06
status: todo
priority: high
state_hub_task_id: "d52c95c6-af3f-4b2c-804e-e07763c9a8ab"
```

With T06 gates: zero normal read/write window, final dump, backup/restore
evidence, stop service, archive repo read-only. Residuals → live owners.

## Acceptance

- [ ] Freeze policy documented

- [x] prj-/GOAL.md register path works
- [ ] Move/replace slices evidenced with tests/counts
- [ ] Retire list closed or residual-owned
- [ ] Stabilization + archive prep ready for project retirement
