+### D17 — Registry TLS: self-signed cert behind NPMplus, not `insecure-registries`, not a real domain
+
+**Problem:** `release.yml`'s first real run failed — `docker/login-action` against
+`192.168.0.3:3000` (Gitea's plain-HTTP address) hit `server gave HTTP response to HTTPS client`.
+Docker refuses TLS-less registries by default; this was never a workflow misconfiguration, it's
+expected Docker behaviour for any non-localhost registry.
+
+**Rejected: `insecure-registries` in `daemon.json`.** The obvious fix. Rejected after actually
+reading `/etc/rc.d/rc.docker` on the Unraid host rather than assuming: applying a `daemon.json`
+change requires a full `dockerd` restart, and (with `Live Restore` disabled on this host) both
+Unraid's own restart path *and* a raw `kill` of `dockerd` stop every one of the ~40 other
+containers running on the box first, as part of the restart/shutdown sequence — Plex, Home
+Assistant, Vaultwarden, everything. Correct fix for the narrow problem, unacceptable blast radius
+for this specific host.
+
+**Rejected: a real Let's Encrypt cert on a new `bbergle.com` subdomain routed publicly.** The
+user's other NPMplus-fronted subdomains resolve through Cloudflare's proxy (orange-cloud), not
+directly to the home IP. A Cloudflare-proxied hostname would have terminated TLS at Cloudflare's
+edge with Cloudflare's own cert, never reaching our self-signed cert or NPMplus's own TLS
+config at all — the entire trust chain would depend on Cloudflare's origin SSL mode, and likely on
+firewall rules restricting port 443 to Cloudflare's IP ranges, neither of which this problem
+needed to involve.
+
+**Chosen:** a small, fully self-contained fix, scoped to touch nothing already working:
+- A 10-year self-signed cert for `registry.bbergle.com` (SAN-only, no real domain dependency).
+- An NPMplus proxy host (`registry.bbergle.com` -> `192.168.0.3:3000` over plain HTTP internally)
+  terminating TLS with that cert, on NPMplus's existing HTTPS port (`9537` on this host — found by
+  reading `docker port NPMplus` rather than assuming 443, which is a *different* nginx process on
+  this box entirely).
+- `/etc/hosts` on the Unraid host mapping `registry.bbergle.com` -> `192.168.0.103` (itself) —
+  chosen over a real DNS record specifically because the only client that ever needs to resolve
+  this hostname is the Unraid host's own `dockerd` (Gitea Actions runs in DooD mode against that
+  same host's Docker socket). This sidesteps Cloudflare, the router's NAT/hairpin behaviour, and
+  any port-forwarding question entirely — verified separately that hairpin NAT works by default on
+  this user's UniFi gateway, but it turned out to be unnecessary for this fix regardless.
+- `/etc/docker/certs.d/registry.bbergle.com:9537/ca.crt` on the Unraid host, trusting that cert for
+  that host:port specifically. Confirmed (Docker's own docs) that `certs.d` is read per-connection,
+  not baked in at daemon start — no `dockerd` restart, no impact on any other container.
+- `docker/setup-buildx-action@v3` pinned to `driver: docker` in `release.yml` instead of its
+  default `docker-container` driver — the default runs BuildKit in an isolated builder container
+  that does not see the host's `/etc/docker/certs.d`, which would have silently defeated the whole
+  point of the trust setup above. We don't build multi-platform images, so nothing the
+  `docker-container` driver offers is actually needed here.
+
+**Not persisted across a reboot, deliberately, for now:** neither the `/etc/hosts` line nor the
+`certs.d` file are wired into `/boot/config/go` — both live under `/`, which Unraid rebuilds fresh
+from `/boot` on every boot. Raised explicitly rather than assumed: the user was (rightly) wary of
+hand-editing anything under `/boot` after an earlier, unrelated discussion of what a broken `go`
+script could do to boot. Persisting this is a five-minute follow-up (append two lines to `go`) once
+they're ready to make that call deliberately, not bundled into this fix.
+
+**What's unaffected:** Gitea's own web UI, git remote, and API — all still plain
+`http://192.168.0.3:3000`, exactly as CLAUDE.md documents. NPMplus's existing public proxy hosts
+and certs (`vaultwarden.bbergle.com` etc.) — untouched, new proxy host only. No other container on
+the Unraid host was restarted, reconfigured, or otherwise touched to make this work.
