Webhook notifications. Settings → Notifications → "Webhook" posts the same events as Web Push (permission prompts, questions, errors, idle) to ntfy, Slack, Discord or any JSON URL, so a headless server can reach a phone with no browser open. Off by default. The URL is a bearer secret: it is stored in its own 0600 file, never returned by the API, and the routes (`GET`/`PUT /api/webhook`, `POST /api/webhook/test`) are admin only in multi-user mode. Delivery refuses link-local and cloud-metadata targets, does not follow redirects, times out after 5 s, dedupes repeats, and neutralises `@everyone`/Slack control characters in agent-supplied text.

The result carries server **names** only, never `env` values or `headers`. Each changed file keeps its previous content as `<file>.codeman-bak` (overwritten by each sync); a file that receives servers carrying `env` or `headers` is left mode `0600`.
## Webhook notifications
Posts the Web Push events to ntfy, Slack, Discord or a generic JSON URL (Settings → Notifications). Off by default. The webhook URL is a bearer secret (anyone holding a Slack/Discord URL can post as it), so it lives in `~/.codeman/webhook.json` (0600), is **never returned**, and is kept out of `settings.json`. All three routes answer `403` for a non-admin in multi-user mode.
| Method | Path | Body | Notes |
| ------ | -------------------- | -------------------------------------------- | ----- |
| `GET` | `/api/webhook` | none | `{ enabled, kind, scope, hasUrl, urlMasked, lastResult }`. `urlMasked` is scheme + host only. `lastResult` is the last delivery (`ok`, `status?`, `error?`, `at`) or `null`. |
| `PUT` | `/api/webhook` | `{ enabled?, kind?, scope?, url? }` (strict) | `kind`: `ntfy` \| `slack` \| `discord` \| `generic`. `scope`: `attention` (skip "response complete") \| `all`. An absent `url` keeps the saved one; `""` clears it. `400` for a non-http(s) URL, `user:pass@`, a link-local or cloud-metadata target, or enabling with no URL. |
| `POST` | `/api/webhook/test` | none | Sends one message with the saved config, even while disabled. `200` with `data.ok` telling whether the webhook accepted it; `400` if no URL is saved. |
Delivery goes through the same egress guard as web tabs (refused on the resolved address too), does not follow redirects, times out after 5 s, sends the same event for the same session at most once per 3 s, and has at most 5 requests in flight. Error text never contains the URL.

* - store: `~/.codeman/webhook.json`, written 0600 via tmp+rename (the URL is a bearer secret:

* - The URL is configured only through the admin-only `/api/webhook` routes and kept OUT of
* `settings.json`, which every logged-in user can read through `GET /api/settings`.
* - Delivery goes through `webviewFetch`: link-local and cloud-metadata targets are refused on
* the RESOLVED address at connect time, redirects are not followed, and the call is bounded
* by a timeout. Loopback and LAN stay allowed on purpose (a local ntfy is the feature).
* - The URL never appears in a log line, a result, or an error message.
* - Session names and error text are user/agent-controlled, so they cannot ping a channel:
