# Migration and retirement acceptance gates v0.1

## Purpose

Turn `GOAL.md` success and project-retirement clauses into **executable or
evidence-backed gates**. Each gate has: id, statement, measurable evidence,
owner stream(s), and status.

Baseline snapshot: [`evidence/baseline-2026-08-09.yaml`](../evidence/baseline-2026-08-09.yaml)
(`SHR-EVID-BASELINE-0001`).

**Status vocabulary:** `open` | `in_progress` | `met` | `waived` (with rationale).

---

## A. Project success gates (from GOAL.md)

### G-IA — Canonical information model

| | |
| --- | --- |
| **Statement** | Entities, relations, and kinds (events, signals, messages, conversations, requests, work, decisions, knowledge, telemetry) are defined with authority and correlation rules. |
| **Evidence** | `architecture/information-model_v0.1.md` + `.yaml` (SHR-ARCH-IA-0001); human review optional for canon promotion. |
| **Owner** | SHR-WP-0001-T03 |
| **Status** | **met** (draft-reviewable; promotion residual) |

### G-EXT — Hub / domain-extension contract

| | |
| --- | --- |
| **Statement** | Versioned hub-core + domain-extension contract implements OA-relevant concepts and has a conformance suite. |
| **Evidence** | Architecture + contract outline **met** at Tier 0 (`hub-extension-architecture_v0.1.md`, `helixforge.hub-extension` YAML). **Conformance suite (Tier 1–3)** still required. |
| **Owner** | SHR-WP-0001-T04; suite → **HUB-WP-0004** |
| **Status** | **in_progress** (docs met; automated suite open) |

### G-HUB-RUNTIME — Hub-core production runtime

| | |
| --- | --- |
| **Statement** | Hub-core contains production runtime, contracts, SDK, extension registry, and compatibility surface required by active consumers. |
| **Evidence** | Deployed hub-core image serving registry/messaging/events/projections; consumer smokes green; contract artefacts published. |
| **Owner** | **HUB-WP-0004** |
| **Status** | **open** |

### G-CORE-ABSORB — core-hub traffic absorbed

| | |
| --- | --- |
| **Statement** | Production traffic formerly served by core-hub runs from consolidated hub-core; core-hub repository archived. |
| **Evidence** | Dual-run report; cutover progress event; ops-hub + activity-core smokes on new host; forge archive flag; completion record with revisions. |
| **Owner** | **CORE-WP-0010** (depends HUB-WP-0004) |
| **Status** | **open** |

### G-RMGR — Repo Manager end-to-end

| | |
| --- | --- |
| **Statement** | Repo Manager represents repositories end to end: file-backed work records, consistency, agent roles, change events, governed mutations. |
| **Evidence** | RMGR-WP-0001 acceptance: contracts versioned; one repo vertical slice with Git evidence + rebuilt projection; extraction dispositions for State Hub repo/work surfaces. |
| **Owner** | **RMGR-WP-0001** |
| **Status** | **open** |

### G-DISP — Full disposition inventory

| | |
| --- | --- |
| **Statement** | Every State Hub route, model, dataset, job, MCP tool, dashboard view, and known consumer has keep/move/replace/retire disposition. |
| **Evidence** | `inventory/state-hub-disposition.yaml` (425 items, v0.1.1). Re-validate on material surface change before freeze. |
| **Owner** | SHR-WP-0001-T02; maintenance → **STATE-WP-0079** |
| **Status** | **met** (initial complete; refresh before freeze) |

### G-HANDOFF — Capabilities on new owners

| | |
| --- | --- |
| **Statement** | All retained capabilities operate through new owners with compatibility, data-count, provenance, authorization, and failure-mode tests. |
| **Evidence** | Per-slice: (1) owner API/port green tests; (2) row-count or content-hash compare vs pre-slice dump; (3) provenance fields present; (4) auth deny/allow cases; (5) failure-mode notes. Inventory `move`/`replace` items checked off. |
| **Owner** | **STATE-WP-0079** + RMGR / HUB / OPS / FIN / ACTIVITY streams |
| **Status** | **open** |

### G-FREEZE — Stabilization window

| | |
| --- | --- |
| **Statement** | State Hub receives no normal reads or writes during an agreed stabilization window. |
| **Evidence** | Window dates recorded in progress event; access logs / meter show only health/admin; agents and automation pointed at successors; exception log empty or residual-owned. |
| **Owner** | **STATE-WP-0079-T06** + operator |
| **Status** | **open** |
| **Suggested window** | ≥ 7 consecutive days after last normal consumer cutover (operator may extend). |

### G-BACKUP — Backup / restore / rollback / history

| | |
| --- | --- |
| **Statement** | Backup, restore, rollback, and historical-query evidence accepted. |
| **Evidence** | (1) Final `pg_dump` (or CNPG backup) of State Hub DB with checksum; (2) restore drill into isolated DB with count compare vs baseline/final; (3) documented rollback procedure exercised once in dual-run; (4) historical work queryable from Git files + archived dump for projections. |
| **Owner** | **STATE-WP-0079** + ops; baseline recovery paths in `evidence/baseline-2026-08-09.yaml` |
| **Status** | **open** |
| **Note** | Cluster scheduled backups not yet configured — manual dump is current path (`state-hub/docs/cluster-operating-model.md`). |

### G-STOP — State Hub stopped and archived

| | |
| --- | --- |
| **Statement** | State Hub stopped; repository and final data archived read-only. |
| **Evidence** | Deployment scaled to zero / removed; forge repo archived; final dump stored with location recorded; INTENT marks retired; no scheduled jobs targeting SH API. |
| **Owner** | **STATE-WP-0079** + ops |
| **Status** | **open** |

## B. Project repository retirement gates (from GOAL.md)

| Gate | Statement | Evidence | Status |
| --- | --- | --- | --- |
| **P1** | Every success gate above has accepted evidence | Checklist in final report | **open** (A-section) |
| **P2** | Residuals have live owners outside this repo | Intake/WP ids with `origin: residual` | **open** |
| **P3** | Decisions/architecture promoted to durable homes | Paths in hub-core / custodian canon / child INTENT | **open** (partial: project-repo flavor already in custodian) |
| **P4** | Child workplans finished, cancelled, or handed off | Map statuses all terminal | **open** |
| **P5** | Final project report (revisions, migrations, archives, obligations, rollback expiry) | `history/YYYY-MM-DD-completion.md` | **open** |
| **P6** | This repo completed + read-only after consistency/link check | `project_status: archived` in GOAL.md; forge archive | **open** |

---

## C. Cross-cutting evidence rules

1. **Re-baseline before each major cutover** — copy `evidence/baseline-*.yaml` pattern with new date; never overwrite without rename.  
2. **Counts** — for data moves, capture pre/post totals for affected tables; ±0 unexplained rows fails the slice.  
3. **Callers** — known callers in baseline must be re-pointed or explicitly retired before G-FREEZE.  
4. **Secrets** — never in evidence files; dump storage location may be referenced, not contents.  
5. **Correlation** — cutover progress events include `correlation_id` linking slice id, dump checksum, and PR links.  
6. **Waiver** — only with human progress note citing residual work-record id.

## F. Acceptance for T06

- [x] Baseline counts, callers, availability, recovery paths recorded  
- [x] GOAL.md success clauses mapped to measurable gates  
- [x] Project retirement clauses mapped (P1–P6)  
- [x] Owners linked to child workplan map  
- [ ] Gates **met** (implementation — out of scope for foundation WP)

Foundation workplan SHR-WP-0001 delivers the **gate definitions and baseline**;
closing the gates is the implementation program (S1–S7 + evidence).
