efitenandClaude Opus 5.5	b2cda21a27	feat(server): companion linking routes, device tokens and bearer auth (#2175) ... Part 2 of 3 for #2173 (companion linking): the server routes, bearer auth and the link handshake. Builds on #2174 (merged); `upstream/master` is merged in, so the diff shows only this part. Everything here is behind `userManagement.enabled` and answers 404 with it off. ## Changes in this PR **Device tokens and bearer auth** - `POST /api/auth/device-token`: email + password returns a bearer token, stored as a `kind = 'device'` session with a label. Same failure answers and the same rate limit as login. - Server-enforced scope for a bearer token: `/api/auth/me`, `/api/auth/logout`, `/api/account/companions*`, `/api/account/settings`. Everything else answers 403. - A bearer header only counts when there is no session cookie, so an auth proxy that adds its own `Authorization` header does not hide a logged-in browser. Cookies never accept a device token. - The sessions list on the account API carries `kind` and `label`; logout with a bearer token revokes that device. **Linking a companion** - `POST /api/account/companions/challenge` `{pubkey}` returns `{challenge, expiresAt, host}`: 32 random bytes, single use, 5 minutes, bound to the caller and the pubkey. - `POST /api/account/companions` `{pubkey, challenge, signature, name}`: the signature is the companion's Ed25519 signature over `corescope-link:<host>:<challenge>` (`internal/sigvalidate.VerifyMessage`). The challenge is consumed in every case. - A companion linked to another account moves to the caller (the newest proof wins). Both users get a `companion.transfer` audit row and the previous owner a mail. That mail is a security notice: it is sent whatever the node notification settings are. - `GET /api/account/companions` (with `lastSeenAt` from `client_receptions`) and `DELETE /api/account/companions/{pubkey}`. - Linking does not touch the synced `meshcore-my-nodes`: a companion is not a node to monitor. - Admin user detail lists linked companions; the account data export includes companions and device sessions. **Coverage and config** - `GET /api/rx-coverage?mine=1`: only coverage of the caller's linked companions (401 when logged out, 403 for a device token). With `gaps=1` (#2172) the reply carries no `gaps` member under `mine=1`, because the track query takes one companion and cannot narrow to a set yet (`TestRxCoverageMineOmitsGaps`). - `clientRxCoverage.requireLinkedCompanion` (default off) is read and reported in `/api/config/client`, which also announces `userManagement.companionLinking`, so CoreDrive RX shows its login only where linking exists. The ingestor side is part 3. - CORS: for origins in `corsAllowedOrigins`, the device-token routes alone also allow POST/PUT/DELETE and the `Authorization` and `Content-Type` headers. No credentialed CORS. Documented in `config.example.json`. - OpenAPI and `docs/api-spec.md` cover the new routes. ## Verification - 26 new tests in `cmd/server` and `internal/sigvalidate`, among them: `TestCompanionLinkFlow`, `TestCompanionLinkRejections` (signature by another key, malformed signature, challenge bound to another pubkey, unknown challenge; reuse and expiry are covered by the store tests in #2174), `TestCompanionTransfer`, `TestCompanionTransferMailIgnoresNotificationSettings`, `TestBearerScopedRoutes`, `TestBearerIgnoredWithCookie`, `TestDeviceTokenSharesLoginRateLimit`, `TestCORSBearerRoutes`, `TestCompanionRoutesAbsentWhenOff`, `TestRxCoverageMine`, `TestRxCoverageMineOmitsGaps` (fails without the `mine == nil` guard), `TestVerifyMessage`. - `cmd/server`, `internal/sigvalidate` and `internal/users`: `go vet` and `go test ./...` green, `gofmt` clean. - The linking flow runs on analyzer.on8ar.eu since 9 October 2026 with CoreDrive RX v1.19.0 (a real companion linked through the signed challenge). ## Not in this PR - The ingestor's linked-only filter, the account page (Devices, Companions), the "My coverage" toggle and the user docs: part 3. - Per-user broker credentials and per-user API keys (non-goals in the spec). --------- Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>	2026-10-10 18:20:49 +02:00
efitenandClaude Opus 5.5	2456762179	feat: account data export and users.db backup (#2141) ... A small follow-up to parts A to E of #2128: users can download all data the instance holds about them, and the server backs up `users.db`. Stacked on #2140. Review the commits after that branch. ## The situation - An instance with accounts holds personal data, but a user has no way to get a copy (GDPR articles 15 and 20). Self-delete already exists. - `users.db` is the only file the server writes, and nothing backs it up: `GET /api/backup` snapshots the analyzer database only. ## What this PR adds **Data export.** `GET /api/account/export` and a "Download my data" button on the account page give one JSON file with: - the profile, including activation and a pending email change; - sessions (times and user agent); - synced settings, own proposals, notification prefs and watches; - audit rows where the user is actor or target, with other accounts as an id only; - the mail log. Password hash, session and link tokens and the unsubscribe token are left out: they are credentials. Each export is audited as `user.export`. **users.db backup** - Daily `VACUUM INTO` snapshots through `internal/users`, on by default when user management is on. They go to `backups/` next to `users.db`, the 7 newest are kept, the directory is 0700 and the files 0600. Rotation only touches `users-<timestamp>.db` files and never the snapshot it just wrote. Config: `userManagement.backup {enabled, dir, keep}`. - `GET /api/admin/users-backup`: an admin downloads a fresh snapshot to keep off the server; audited as `user.backup`. - `docs/user-guide/accounts.md` gains a restore procedure. It covers what a restore brings back (accounts deleted after the snapshot, old passwords, revoked sessions) and how to clean that up afterwards. Spec: [`docs/specs/2026-10-08-account-export-and-users-backup-design.md`](https://github.com/efiten/CoreScope/blob/feat/account-export-backup/docs/specs/2026-10-08-account-export-and-users-backup-design.md). ## Verification - `internal/users` with `-race` and the `cmd/server` suite pass locally, 30 new Go tests. The file-mode tests skip on Windows. - `sh test-all.sh` exits 0; the XSS gate in diff mode passes. - User-management E2E: 27 of 27 steps locally. - On our production instance since 8 October 2026; the first snapshot there was 143 kB. ## Not in this PR - Importing an export into another instance. - Off-site upload of the snapshots. The admin download covers that by hand. --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-08 22:16:49 +02:00
