Update M6 docs to reflect release.yml mirroring link/'s engine (auto version +
changelog + tag + signed APK + Gitea release on merge to main), not a v* tag
trigger. Note REGISTRY_USER/REGISTRY_TOKEN + the main-push requirement, and the
derived monotonic versionCode. §9 status, §9 M6/M7 milestones, §12.

Status: **M0–M7 landed; M7 (push notifications) both parts done — Part 1 backend (website#78) and Part 2 app (Android-app#15) plus a small `push.ntfyUrl` settings addition (website#79). Remaining: set the shard's `NTFY_*` deploy config so push lights up, and cut the v1 tag. M9 (native SSO login) is now underway backend-first — the Mobile SSO Authorization Bridge is being built in `website/` + `docs/` ahead of the app-side client (§4.2, §9 M9); custom-scheme callback only for now, App Links deferred (see [`APP_LINKS.md`](./APP_LINKS.md)).** This document is the

`versionName` is the committed source of truth (bumped by the release engine); `versionCode` is derived

### push_devices — opt-in push endpoints (M7)
| col | type | notes |
|---|---|---|
| id | INT PK AUTO_INCREMENT | |
| user_id | INT NOT NULL FK→users(id) ON DELETE CASCADE | owner |
| transport | ENUM('unifiedpush','fcm') DEFAULT 'unifiedpush' | UnifiedPush for the sideloaded APK; FCM reserved for a later Play flavor |
| endpoint | VARCHAR(512) NOT NULL | the distributor URL the app's ntfy topic was handed (or an FCM token). Unguessable but **not a secret** — stored in the clear (unlike refresh tokens), because pushes are content-free tickles |
`mobile_auth_sessions` — one row per `/auth/mobile/sso/start`:
| col | type | notes |
|---|---|---|
| id | INT PK AUTO_INCREMENT | |
| session_id | CHAR(36) UNIQUE | opaque uuid; carried inside the signed `sso_tx` (mode `mobile`) so the callback can find this row |
| provider | VARCHAR(40) NOT NULL | provider id validated enabled at `/start` |
| code_challenge | VARCHAR(255) NOT NULL | app-supplied PKCE S256 challenge (base64url); verified at `/exchange` |
| redirect_uri | VARCHAR(255) NOT NULL | the requested app callback — **exact-match** against the allowlist (never prefix) |
| state | VARCHAR(255) NOT NULL | app-generated opaque CSRF value, echoed on the callback for the app to verify |
| status | ENUM('pending','completed','consumed') DEFAULT 'pending' | `pending`→`completed` when the code is minted; `consumed` after a successful exchange |
| user_id | INT NULL FK→users(id) ON DELETE CASCADE | set once SSO resolves the account |
| expires_at | DATETIME NOT NULL | short (~10 min — one redirect round-trip incl. TOTP) |
`mobile_auth_codes` — one row per completed SSO callback (the code the app redeems):
| col | type | notes |
|---|---|---|
| id | INT PK AUTO_INCREMENT | |
| code_hash | CHAR(64) UNIQUE | sha256 hex of the opaque ≥128-bit code; the raw code never touches the DB |
| user_id | INT NOT NULL FK→users(id) ON DELETE CASCADE | the authenticated account |
| session_id | CHAR(36) NOT NULL | the owning `mobile_auth_sessions.session_id` (ties the code to its PKCE challenge) |
| expires_at | DATETIME NOT NULL | very short (~5 min) |
| used_at | DATETIME NULL | set on first successful exchange — **single use** (a reused code fails) |
| created_at | DATETIME | |
Both self-prune (indexed `expires_at`): a best-effort sweep runs at boot beside the existing
`revoked_sessions` prune, and each bridge write opportunistically deletes expired rows — so no cron
infra is added (same approach as `revoked_sessions`).
**`mobile_refresh_tokens` additions (M9).** Two nullable columns are added to support the device
list/revoke surface: `device_name VARCHAR(100) NULL` (a friendly label) and `last_used_at DATETIME
NULL` (bumped on each refresh). Existing rows get them via the schema's ALTER section; the token model
is otherwise unchanged.

### Mobile SSO Authorization Bridge (`/auth/mobile/sso/*`, M9)
Native "Sign in with Google/Discord" for the Android app **without shipping any OAuth secret in the
app**. The website stays the identity authority: each shard owner's provider credentials live in
`auth_providers` (encrypted at rest) and are only ever used server-side. The bridge is a **new
consumer of the existing SSO + mobile-bearer machinery**, not a parallel auth path — it reuses the
`/auth/sso/:provider/*` redirect flow, the link-only + opt-in-provisioning policy, the TOTP gate, and
issues the **same** token pair as `/auth/mobile/login`.
| Method | Path | Auth | Body / Query | Purpose |
|---|---|---|---|---|
| GET | `/auth/providers` | — | — | **reused** discovery; the app renders provider buttons from this (never exposes secrets) |
| GET | `/auth/mobile/sso/start` | — (rate-limited per-IP + per-provider) | `?provider&code_challenge&state&redirect_uri` | validate provider enabled + `redirect_uri`**exact-match** allowlist; insert a `mobile_auth_sessions` row; create the existing `sso_tx` tagged `mode:'mobile'` carrying `session_id`; **302 to the IdP** (existing authorize URL) |
| GET | `/auth/sso/:provider/callback` | — (signed `sso_tx`) | `?code&state` | **existing** endpoint; a new branch when `tx.mode==='mobile'`: resolve the account (same policy as web login incl. TOTP), mint a single-use hashed authorization code into `mobile_auth_codes`, mark the session `completed`, and **302 to `redirect_uri?code=…&state=…`** (the app's original `state`) — **no cookie is set** |
| POST | `/auth/mobile/sso/exchange` | — (rate-limited per-IP) | `{code, code_verifier}` | validate the code exists / unexpired / unused (mark used) and `sha256(code_verifier)` matches the stored challenge → issue the existing mobile access + refresh pair (`createMobileSession`) → `{accessToken, refreshToken, expiresIn, user}` |
| POST | `/auth/mobile/refresh` | — | `{refreshToken}` | **reused** unchanged — rotate the pair |
| POST | `/auth/mobile/logout` | bearer | `{refreshToken?, all?}` | **reused** unchanged — revoke this (or all) refresh token(s) |
| GET | `/auth/me/sessions` · DELETE `…/:id` | cookie / bearer | — | list / revoke own **mobile sessions** (device_name, last_used_at, created_at) — the "Active Devices" surface (distinct from `/auth/me/devices`, which is push endpoints) |
**Two PKCE layers (do not conflate).**
- *Layer A (existing):* website ↔ IdP. The `code_verifier` is generated at `/start`, kept only in the
httpOnly `sso_tx` cookie, sent to the IdP token endpoint at the callback. Unchanged.
- *Layer B (new):* app ↔ website. The **app** generates `code_verifier`/`code_challenge`; the
challenge is stored in `mobile_auth_sessions` at `/start`; the verifier is presented at `/exchange`.
This is what stops an intercepted callback code from being redeemed by anyone but the real app.
**State / CSRF.** The app-generated `state` is stored at `/start`, echoed on the callback redirect,
and **verified by the app** before it calls `/exchange` — a CSRF guard independent of both PKCE
layers (a different app instance triggering `/start` cannot complete someone else's flow).
**Redirect-URI allowlist.**`/start` and the callback validate `redirect_uri` by **exact match**
against a configured allowlist (`MOBILE_AUTH_REDIRECT_URIS`, default the one fixed application-owned
future renewals but does **not** invalidate an already-issued access token until it expires — up to
the access-token lifetime (`MOBILE_ACCESS_TTL`, default 15 min) of continued access. This is an
accepted tradeoff given the short lifetime. If instant revocation is ever required, add an
access-token (jti) blocklist check on the `requireAuth` path — the same `revoked_sessions` mechanism
web sessions already use.
**Authorization code.** Cryptographically random, ≥128 bits, stored **hash-only**, single-use, short
expiry (~5 min); `/exchange` is rate-limited per-IP. The bridge tables self-prune (§3).
