### Default bind, and the non-loopback warning path
**Default bind is loopback-only; non-loopback without a password starts but warns** — since COD-29 (PR #107) the web server defaults to `--host 127.0.0.1` (was `0.0.0.0`). As of **0.9.0** binding a non-loopback host (`--host`/`-H`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` **no longer refuses to start — it starts and prints a loud warning** listing the fixes (set `CODEMAN_PASSWORD`, bind loopback + tunnel/`tailscale serve`, or `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` to acknowledge → terser note). Host classification is `isLoopbackBindHost()` in `network-auth-policy.ts`; the warn-vs-start logic is in `server.ts` `start()`; flags wired in `cli.ts`. ⚠️ Operational note: the production systemd unit runs `node dist/index.js web --https` with no `--host`, so it binds **localhost only** — reach it remotely via `tailscale serve`/tunnel to `127.0.0.1`, or add `Environment=CODEMAN_HOST=0.0.0.0` + `Environment=CODEMAN_PASSWORD=…` to `~/.config/systemd/user/codeman-web.service`. A loopback bind is reachable through a same-host tunnel (cloudflared/tailscale → `127.0.0.1`) but NOT by a browser hitting the box's LAN IP. Auth user defaults to `admin`. **Installer note** (1.8.x, `install.sh`): interactive installs now PROMPT for the binding, defaulting to LAN (`0.0.0.0`) with a required password prompt (skipping the password needs an explicit confirm and prints a loud warning); non-interactive installs keep loopback unless `CODEMAN_HOST` is preset, and re-runs/updates preserve the EXISTING binding (`read_existing_binding()` parses the current systemd unit / launchd plist). The server binary's own default is unchanged. **Full model: `docs/security-architecture.md`.**

Auth user defaults to `admin`. **Installer note** (`install.sh`, installer v2 since 2026-09-20): interactive installs PROMPT for the binding up front, defaulting to Tailscale when the node is already connected, else LAN (`0.0.0.0`), and to the existing choice on a re-run; a LAN bind asks for a password, and skipping it is a confirm that DEFAULTS TO YES (owner decision 2026-09-20) and ends on a loud red notice; non-interactive installs keep loopback unless `CODEMAN_HOST` is preset, and re-runs/updates preserve the EXISTING binding AND password (`read_existing_binding()` parses the current systemd unit / launchd plist, and the `--lan`/`--tailscale`/env preset paths read `${CODEMAN_PASSWORD:-$EXISTING_PASSWORD}`, since a flag re-run used to rewrite a password-protected unit open).
