 Delete the `bao-notice` Application with prune. That restores today's state:
 the Traefik default certificate and a 404.

+## Execution record — 2026-09-23/24 (founder go-ahead)
+
+- **T02 done.** The root and `bao-notice` were hand-synced; the app is
+  Synced/Healthy.
+- **First issuance returned 502 on the HTTP-01 challenge.** The isolation
+  NetworkPolicy also covered cert-manager's solver pod (port 8089). Fixed by a
+  narrow `bao-notice-acme-solver` policy, Traefik to solver pods on 8089 only,
+  and `bao-notice-tls` was issued.
+- **HSTS added** (`max-age=31536000`, this host only). The single-replica pod
+  swap caused a few seconds of 502 through Traefik.
+- **T03 done.** Checked from the workstation with no `-k`:
+  - Certificate `CN=bao.coulomb.social` from Let's Encrypt, verify ok, expires
+    2026-12-22 (cert-manager renews).
+  - `/` returns 200 with the notice; `/v1/sys/health` and `/ui/` return 404;
+    `http://` returns a 301 to https.
+  - HSTS and CSP `default-src 'none'` are set, and the `Server` header carries
+    no version.
+  - No internal identifiers, form or redirect in the body.
