# Repository classification aggregation and navigation
|
|
|
|
## Goal
|
|
|
|
Consume Repo Manager's validated repository-classification projections and
|
|
provide rebuildable cross-domain aggregation/navigation without creating a
|
|
second classification authority. Supply the hub-core receiving surface needed
|
|
for State Hub retirement slices A5 and the repository-facing part of A4/B5.
|
|
|
|
## Accept the classification projection boundary
|
|
|
|
```task
|
|
id: HUB-WP-0006-T01
|
|
status: done
|
|
priority: high
|
|
```
|
|
|
|
Review `RMGR-CONTRACT-CLASSIFICATION-0001` version 1.0 and record the hub-core
|
|
authority, validation, versioning, provenance, failure, and A5 routing
|
|
boundary.
|
|
|
|
Completed 2026-08-22. `docs/adr/ADR-0002-repository-classification-projections.md`
|
|
accepts the contract without a schema gap. Repository files remain authority;
|
|
Repo Manager validates and publishes; hub-core derives navigation only; and
|
|
STATE-WP-0079 retains the consumer-route switch and rollback flag.
|
|
|
|
## Freeze the hub-side projection contract
|
|
|
|
```task
|
|
id: HUB-WP-0006-T02
|
|
status: todo
|
|
priority: high
|
|
```
|
|
|
|
Define the input envelope, supported contract versions, stable repository
|
|
identity, cursor/snapshot semantics, provenance, diagnostics, and the derived
|
|
domain/category/tag/stake/mechanic views. Define legacy topic aliases as
|
|
temporary compatibility metadata, not mutable topic authority.
|
|
|
|
## Implement Repo Manager ingestion and rebuild
|
|
|
|
```task
|
|
id: HUB-WP-0006-T03
|
|
status: todo
|
|
priority: high
|
|
```
|
|
|
|
Add an injected `port.repo` client, deterministic full rebuild plus incremental
|
|
upsert/delete behavior, durable PostgreSQL projection tables, content hashes,
|
|
and dependency-aware readiness. Reject invalid or unsupported projection
|
|
versions without coercion.
|
|
|
|
## Expose projection query and MCP navigation
|
|
|
|
```task
|
|
id: HUB-WP-0006-T04
|
|
status: todo
|
|
priority: high
|
|
```
|
|
|
|
Expose cross-repository query routes and MCP tools for domain, secondary
|
|
domain, category, capability tag, business stake, and business mechanic.
|
|
Responses carry source revision and rebuild provenance. No endpoint writes
|
|
classification authority.
|
|
|
|
## Prove conformance and failure behavior
|
|
|
|
```task
|
|
id: HUB-WP-0006-T05
|
|
status: todo
|
|
priority: medium
|
|
```
|
|
|
|
Add contract fixtures and checks for full rebuild, incremental changes,
|
|
deletion, duplicate delivery, unsupported versions, Repo Manager outage,
|
|
stable ordering/cursors, provenance, and absence of classification writes or
|
|
foreign database access.
|
|
|
|
## Hand A5/A4 navigation to State Hub retirement
|
|
|
|
```task
|
|
id: HUB-WP-0006-T06
|
|
status: wait
|
|
priority: high
|
|
```
|
|
|
|
With `STATE-WP-0079`, compare legacy topic/navigation consumers with the new
|
|
projection, retain explicit aliases where required, run owned consumer smokes,
|
|
switch A5 through `RM_SLICE_TOPICSPINE`, and record rollback plus residual
|
|
expiry. Wait on T02-T05 and the State Hub cutover window.
|
|
|
|
## Acceptance
|
|
|
|
- [x] Repo Manager v1.0 authority and projection contract accepted
|
|
- [ ] Hub-side projection and compatibility alias contract versioned
|
|
- [ ] Rebuildable durable ingestion passes provenance and failure checks
|
|
- [ ] HTTP/MCP navigation reads only the derived projection
|
|
- [ ] A5/A4 consumer comparison and rollback evidence recorded
|
