+**One documented amendment (Go app, port 8096):** the app publishes on the LAN address `192.168.20.13:8096`, not `127.0.0.1`. Caddy runs on `.35` and proxies to `192.168.20.13:8096`, so a loopback-only publish is unreachable from the edge and the public URL returns 502. This is the same way `8095` (offsite), `8092` (photo-filter), `3909` (garage-ui) and `4200` (prefect) are published on `.13`. The port is LAN-only — never `0.0.0.0` — and Caddy on `.35` is still the only public listener, so `AGENTS.md` §4.2 holds in substance. Decision: Sam, 2026-10-26, interaction `54aeb1a2`. `deploy/deploy.sh` follows the same address (`RESUME_PUBLISH_IP`, default `192.168.20.13`) in its health gate and shape assertion.
