 `caddy-git.conf` lists both names on a *single* site block. That is deliberate,
 not cosmetic: the `/v2/*` mesh-only matcher is per-block, so a second block for
 either name would re-expose the registry API publicly and undo hazard #15.

-  Caddy's `/v2/*` matcher see a mesh source IP instead of returning 403;

+### Host-side steps
+
+None of these live in the repo, and CI will not do them for you. In order:
+
+1. **`/etc/hosts` on every mesh client** — pin `dev.jinemi.com` as well as
+   `git.thermograph.org` (both, for the reasons under "Registry access from
+   mesh clients" below). A client that resolves the new name publicly gets a
+   403 from the `/v2/*` matcher, which reads exactly like a bad credential.
+2. **`docker login dev.jinemi.com`** on each host that pushes or pulls — the
+   CI runners, vps2 (prod and beta), the desktop. A login against the old name
+   does **not** carry over: docker keys stored credentials by registry host.
+3. **The Forgejo Actions variable `REGISTRY_HOST`** → `dev.jinemi.com`
+   (Site Administration → Actions → Variables, or the repo's own). This is what
+   `build-push.yml` reads; the defaults in this repo are fallbacks for by-hand
+   runs, so leaving the variable stale silently keeps CI on the old name.
+4. **Re-register the runners** against `https://dev.jinemi.com`, *optionally* —
+   see above. Until you do, leave `git.thermograph.org` served.
+
+Verify with a push before assuming: the failure mode for a missed step 1 or 2
+is `unauthorized: reqPackageAccess`, which names neither.
