WP-0005 T12: Option A — keep Gitea fallback, 30-day window

Operator decision: retain coulombcore Gitea Helm as read-only fallback with a
30-day rollback window (2026-07-08 → 2026-08-07). Mark T12 done; update
rollback runbook and retirement checklist.

-Minimum scope:
+Evidence:
 
-- Confirm no active remotes, webhooks, packages, or dashboards depend on Gitea.
-- Preserve final Gitea backup.
-- Update runbooks and dashboards from Gitea to Forgejo.
-- Remove or archive Gitea Helm release according to the rollback decision.
-- Close stale State Hub references to `railiance-bootstrap` if confirmed as
-  an alias rather than a real repo.
+- Dependency scan: State Hub **0 Gitea remotes**; workstation **0 `gitea-remote`
+  origins** (2026-07-09).
+- Gitea org **79/79 archived**; package push disabled (T11).

 **Done when:** Forgejo is the only active source forge and package base, with
 legacy Gitea either archived or intentionally retained as documented fallback.
+**Met** — Gitea retained intentionally per Option A.
