efitenandClaude Opus 5.5	de364a8bb6	feat: mail notifications for watched nodes (user management part E) (#2140) ... Part E of #2128: a logged-in user watches nodes and gets one mail when a watched node goes offline, comes back, or reports a low battery. Admins can add instance events: a new foreign node, and an observer going offline or back. This covers the per-user mail part of #775. Stacked on #2139 (part D, which builds on #2138). Review the commits after that branch. ## The situation A sysop learns that a repeater went silent, or that its battery is running down, only by opening CoreScope. #775 asks for notifications. Accounts (part A) now give a verified address to mail and a mailer with delivery status. ## What this PR adds **Events.** They use the instance thresholds, so a mail does not disagree with the node page: - `node.offline`: silent for the role's `healthThresholds` window. Last heard comes from the packet store, and repeaters and rooms count relayed traffic (#1598). - `node.battery`: advert telemetry below `batteryThresholds.lowMv`, recovered at `lowMv + 100`. - Admins only: `foreign.new` (once per node) and `observer.offline`. **Store.** Schema v5 with `notification_prefs`, `notification_watches` and `notification_state`. **Server** (only with `userManagement.notifications.enabled`) - A notifier next to the janitor, every `intervalMinutes` (5). The evaluator is a pure function of watches, prefs, stored states and node snapshots. - No burst after a restart or a new watch: a subject's first evaluation stores its state without mailing. The loop waits for the startup load. While ingest is stale (newest packet older than 30 minutes) the offline checks pause, and after recovery they wait one silent window. - One mail per user per check. Limits: 20 per user and 100 per instance per rolling 24 hours, 50 watches per user. A change over a limit is recorded and never mailed later. - Every mail has a one-click unsubscribe (`List-Unsubscribe` and `List-Unsubscribe-Post`). The GET only redirects to a confirm page, so link scanners cannot unsubscribe anyone. Node names are cleaned of control and bidi characters before they go into a mail. - Routes: `GET`/`PUT /api/account/notifications`, `PUT`/`DELETE /api/account/notifications/watches/{pubkey}`, `POST /api/account/notifications/watch-my-nodes` (copies the synced "my nodes" list), `GET`/`POST /api/notifications/unsubscribe`. `mailer.Message` gains `Headers`. **Frontend.** A "Notify me" toggle on the node pages, a Notifications section on the account page (`#/account?section=notifications`), an unsubscribe page, and the notification mail count on the admin overview. Spec: [`docs/specs/2026-10-07-node-notifications-design.md`](https://github.com/efiten/CoreScope/blob/feat/notifications/docs/specs/2026-10-07-node-notifications-design.md). ## Performance Each check reads watches, prefs and states from `users.db` (one query each), the watched nodes from the analyzer DB in chunks of 500, and last-heard times from the packet store. | Measurement | Result | |---|---| | One check on our staging instance, 130,000 packets in memory, 1 watcher | 6.9 ms, of which 0.93 ms holding the store read lock | | Evaluator benchmark, 100 users with 50 watches each, 2,000 nodes | 1.75 ms | No work is added to ingest, broadcast or any request path. ## Verification - `internal/users` and `internal/mailer` with `-race`; the `cmd/server` suite plus `-race` on the notifier tests; 74 new Go tests. The same Windows-only failure as noted in #2138 applies. - `sh test-all.sh` exits 0; the XSS gate in diff mode passes. - User-management E2E: 26 of 26 steps locally. With notifications off the new steps fail, so they do test the flag. - On our staging and production instance since 7 October 2026. ## Not in this PR - Other channels (Discord, Telegram, webhooks). Detection is separate from delivery, so one can be added. - The topology, RF and anomaly alerts of #775. - If the whole server starts after a feed outage that already ended, the grace window is unknown and a watcher can get one wrong offline mail. The user guide says so. --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-08 22:02:39 +02:00
efitenandClaude Opus 5.5	d232072f85	feat: optional user accounts (part A: foundation) (#2129) ... Part A of #2128: optional, off-by-default user accounts. With the feature off nothing changes; with it on, visitors can register and log in, and admins manage users and use the operator actions without the API key. PR #2130 (settings sync) builds on this one. The two are meant to be merged together. ## The situation - Operator actions (geofilter save and prune, backup, perf reset) need the shared `apiKey`. There is no per-person right. - Nothing in CoreScope knows who a visitor is, so the requests in #2128 that need that (#1835, #2092, #1508, #730) have nothing to build on. ## What this PR adds **Two new Go modules** - `internal/users`: a separate `users.db` (SQLite through `modernc.org/sqlite`) with users, sessions, single-use tokens, an audit log and a mail log. Passwords use argon2id. - `internal/mailer`: a `Mailer` interface with a Brevo client (send, delivery events, webhook parsing) and an in-memory fake for tests. **Server (`cmd/server`)**, active only with `userManagement.enabled` - 24 routes, all documented in OpenAPI under the `users` tag ([`auth_routes.go`](https://github.com/efiten/CoreScope/blob/feat/user-management/cmd/server/auth_routes.go)): - auth: register, activate, login, logout, me, forgot, reset; - account: profile, password, email change with confirmation, sessions, self-delete; - admin: list, detail, disable, enable, delete, role, resend activation, manual activation, mail status refresh; - a Brevo webhook, registered only when `mail.webhookSecret` is set. - `requireAdmin` replaces `requireAPIKey` at the 7 operator call sites: the API key **or** an admin session. With the feature off it is the old API-key gate (`TestRequireAdminWithoutUserManagementIsAPIKeyGate`). - `/api/config/client` gets `userManagement: {enabled: true}` only when the service started; with the feature off the response is byte-identical. **Frontend** - `auth.js` (header account control, request helper that adds the CSRF header), `account.js` (login, register, activate, forgot, reset, confirm email, my account), `admin-users.js` (`#/admin/users`, deep-linked filters), `account.css` (theme tokens only). - On phones the top-bar control is hidden, so a conditional entry goes into the bottom-nav "More" sheet and the nav drawer. - The customizer geofilter tab and the Perf "Reset stats" button use the admin session when there is one. **Config.** A `userManagement` block (`config.example.json`, [`docs/user-guide/accounts.md`](https://github.com/efiten/CoreScope/blob/feat/user-management/docs/user-guide/accounts.md)). The Brevo key can come from `CORESCOPE_BREVO_API_KEY`. The server refuses to start when the block is enabled but incomplete. ## Security choices - Session cookie `cs_session`: HttpOnly, SameSite=Lax, Secure when `publicBaseUrl` is https. Every cookie-authenticated state change needs the `X-CS-CSRF` header and a matching Origin. - Activation needs the token **and** the account password. Without the password, an attacker who keeps re-registering a known address could get the owner to activate an account that carries the attacker's password. - Register, forgot and email change answer identically for known and unknown addresses. A password reset ends all sessions, a password change ends all other sessions, and both end outstanding email-change links. - Rate limits: login 10 per 15 minutes, register and forgot 5 per hour, per IP and per address. The bucket count is capped. `trustedProxies` makes the per-IP limits see real client IPs behind a proxy. - Server logs carry `#<user id>`, never addresses, tokens or passwords; mail-provider error texts are redacted before logging. ## Performance No change to an existing hot path with the feature off. With it on: - One `users.db` lookup per authenticated request (session by token hash). - The admin user table rebuilds its `tbody` on each filter change. `users.List` caps the result at 1000 rows (`internal/users/users.go`), which bounds the rebuild. - `map[string]interface{}` in `openapi.go`: 79 before, 78 after. ## Verification - `internal/users`, `internal/mailer` and `cmd/server`: `go vet` and `go test -race` pass locally. 121 new Go tests. - `cmd/server` with `-tags e2etest`: vet and the e2e hook tests pass. - `sh test-all.sh` exits 0. `tests/unit/test-user-management-ui.js`: 67 passing (vm, real modules). - `tests/e2e/test-user-management-e2e.js` (6 steps) passed locally against an `e2etest` build with the fake mailer and against a feature-off build. CI builds the `e2etest` binary and runs the suite on a second server (`deploy.yml`). - On a staging instance with a real Brevo key: register, activation mail delivered, activate, admin table, "Refresh status" showing sent, deferred, delivered, opened and clicked. ## Not in this PR - Settings sync (#2130), the admin dashboard, approval flows and notifications (parts B to E of #2128). - A `requireReadAuth` mode (#1835). Sessions from this PR are what such a mode would accept. - Binary size and build time with `modernc.org/sqlite` linked next to `mattn/go-sqlite3` were not measured. Their driver names do not collide. #1992 discusses the driver choice. - No Brevo webhook was configured on staging; delivery status there came from "Refresh status". --------- Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>	2026-10-07 09:25:29 +02:00
