+# Milestone — project repository flavor canonized
+
+**Recorded:** 2026-08-09  
+**Workplan task:** SHR-WP-0001-T01
+
+## What landed
+
+Durable fleet standard:
+
+- `the-custodian/canon/standards/project-repository-flavor_v0.1.md`
+
+Cross-links:
+
+- ADR-005 naming section → standard (`prj-` prefix; closes deferred naming)
+- Repo Classification Standard §5.3 → project-repo vs ordinary `category: project`
+- CUST-WP-0050 D1a → resolved 2026-08-09
+
+## Decisions fixed
+
+| Topic | Decision |
+| --- | --- |
+| Naming | `prj-<kebab-slug>` only for new project repos |
+| Purpose document | `GOAL.md` (not durable-product `INTENT.md`) |
+| Authority | coordination + evidence here; implementation in child repos |
+| Lifecycle | `draft → active → completed → archived` |
+| Retirement | archive read-only with completion record; never delete |
+
+## Residual
+
+`statehub register` and related bootstrap still assume `INTENT.md` for ordinary
+repos. Adapting that path for `repo_flavor: project` / `GOAL.md` belongs in a
+state-hub implementation workplan (see SHR-WP-0001-T05 map), not as a
+hand-edited exception in this repository.
