docs(ci): use the actual case-sensitive SonarQube project keys

link and Android-app reuse the pre-existing capitalised keys
(Runic-Gateway-link, Runic-Gateway-Android-app); the server rejects
case-variant duplicates. Note the case-sensitivity gotcha.

+# Android App Links — implementation spec
+
+Status: **implementation spec (M9 follow-up).** Stacks on the native SSO bridge (M9 Part 2):
+the app already handles the **custom-scheme** callback `runicgateway://auth/callback`, and that stays
+the permanent default and universal fallback. App Links are an **opt-in hardening** layered on top —
+a verified `https://` callback that only the domain's real owner can claim.
+
+Read alongside: the "Mobile SSO Authorization Bridge" section of
+[`../website/BACKEND_DESIGN.md`](../website/BACKEND_DESIGN.md) (endpoints/tables/allowlist), and
+[`PLAN.md`](./PLAN.md) §4.2 / §9 (the app milestone). This spec matches what ships on the
+`feat/mobile-app-links` (website) and `feat/app-links` (android) branches.
+
+---
+
+## 1. The problem it solves
+
+The mobile SSO bridge redirects the browser back to the app with a one-time code:
+
+```
+runicgateway://auth/callback?code=…&state=…
+```
+
+A **custom URI scheme** is fine for a self-hosted internal client, but it is not *owned* by anyone:
+any other Android app can register an intent-filter for `runicgateway://auth/callback` and, if chosen
+by the user, intercept the callback. The code is single-use, PKCE-bound (Layer B), and short-lived —
+so an interceptor still cannot complete `/exchange` without the app's `code_verifier` — but a hijacked
+callback is still a denial-of-service and a phishing surface we would rather close.
+
+**Android App Links** (verified `https://` deep links) close it: the OS only routes an `https://`
+link to an app that has proven, via a file served from *that domain*, that it owns the app. An
+attacker cannot serve that file on a domain they do not control.
+
+## 2. Why this is harder here than in a normal app
+
+RunicGateway is **self-hosted per shard**. There is no single canonical domain — every shard owner
+runs the website on **their own** domain (`play.exampleshard.com`, `uo.anothershard.net`, …). App
+Links verification is **per-domain**: the domain must serve
+
+```
+https://<shard-domain>/.well-known/assetlinks.json
+```
+
+asserting the Android app's **package name** + **signing-certificate SHA-256 fingerprint**.
+
+That is only half the problem. The other half is an Android platform constraint that decides the whole
+shape of the app side:
+
+> **`android:autoVerify` needs a *literal* host at build time.** An intent-filter's `<data android:host>`
+> is a static string in the merged manifest; there is no "any host" or runtime host. A **single
+> published multi-tenant APK therefore cannot autoVerify an open-ended set of shard domains** — the set
+> is not known when the APK is built.
+
+So App Links here are **not** a drop-in replacement for the custom scheme. They split into two pieces
+that ship independently:
+
+1. **Server (`assetlinks.json`) — shippable now, benefits any App-Links-capable build.** Every shard
+   can auto-serve its Digital Asset Links statement behind an admin toggle. This is a pure add and is
+   implemented on `feat/mobile-app-links`.
+2. **App (`autoVerify` intent-filter) — a *build-time* opt-in.** Because the host must be baked in,
+   App Links are available to:
+   - a **white-label / first-party build** that bakes one shard's host (`-PappLinkHost=play.myshard.com`);
+   - a future **canonical relay domain** (`runicgateway.app`, PLAN §14 — *not yet secured*) that all
+     shards could bounce their final callback through, autoVerified by the generic build.
+
+   The **generic multi-tenant build bakes no host and stays custom-scheme-only** — correct and safe.
+
+The custom scheme is never removed. It is the fallback on every build, for every shard, always.
+
+## 3. Server design — `feat/mobile-app-links`
+
+### 3.1 Auto-served `assetlinks.json`
+
+- **Route:** `GET /.well-known/assetlinks.json`, served at the **web root** (outside `/api/v1`, before
+  the SPA catch-all) in `server/src/app.js`.
+- **Gate:** the admin setting `mobile_app_links_enabled` (default **off**). Off ⇒ the route **404s** and
+  the app stays on the custom scheme for that shard. On ⇒ the shard opts into App Links.
+- **Body:** the Digital Asset Links statement for the fixed package `com.runicgateway.app` and the
+  release signing cert SHA-256 fingerprint(s):
+
+  ```json
+  [
+    {
+      "relation": ["delegate_permission/common.handle_all_urls"],
+      "target": {
+        "namespace": "android_app",
+        "package_name": "com.runicgateway.app",
+        "sha256_cert_fingerprints": ["AB:CD:…"]
+      }
+    }
+  ]
+  ```
+
+- **Fingerprint source:** env `MOBILE_APP_CERT_SHA256` — comma-separated (supports **cert rotation** and
+  a debug + release cert during testing). It is a **constant of the published app**, identical for every
+  shard, so it is a shipped/env default, not something each owner types. The package name is likewise
+  fixed (`MOBILE_APP_PACKAGE`, default `com.runicgateway.app`).
+- **Enabled but no fingerprint configured ⇒ 404** (+ a one-time warn): serving a statement with no
+  fingerprint asserts nothing and would only mislead the verifier.
+- Response is `application/json`, `Cache-Control: public, max-age=3600` (the Play verifier and the OS
+  re-fetch it; it changes only on a cert rotation).
+
+### 3.2 Redirect-URI allowlist extension
+
+`mobileSso.controller` validates the app's `redirect_uri` by **exact match** against
+`MOBILE_AUTH_REDIRECT_URIS` (default `runicgateway://auth/callback`). App Links add exactly one more
+acceptable value, and **only when the toggle is on**:
+
+- When `mobile_app_links_enabled`, `/start` additionally accepts the **self-origin** HTTPS callback
+  `https://<request-host>/mobile/callback` (derived from the request/`APP_BASE_URL`, never from
+  attacker-controlled input). Still **exact match** — never a prefix match.
+- The static custom-scheme allowlist is never narrowed; the HTTPS entry is *additive*.
+- No new table or schema: the check reads the one boolean setting.
+
+### 3.3 Public settings advertise the capability
+
+`settings.getPublic()` gains `mobileAppLinks: <bool>` (mirrors the toggle) so a client can tell whether
+a shard opted in before requesting an HTTPS `redirect_uri` (a white-label build uses it to avoid asking
+for a callback the server would reject).
+
+## 4. App design — `feat/app-links`
+
+### 4.1 Build-time host (`appLinkHost`)
+
+- Gradle property `appLinkHost` (default empty). Wired in `app/build.gradle.kts` into **both**:
+  - `BuildConfig.APP_LINK_HOST` — read by `SsoAuthManager` to decide the redirect;
+  - `manifestPlaceholders["appLinkHost"]` — substituted into the App Link intent-filter's host.
+- **Default (generic build):** empty ⇒ `BuildConfig.APP_LINK_HOST = ""` and the placeholder falls back
+  to the reserved sentinel `runic-gateway.invalid` (RFC 6761 — never resolves), so the `autoVerify`
+  filter is **inert**: it matches no real link and verification simply never succeeds. No custom-scheme
+  behaviour changes.
+- **White-label build:** `./gradlew assembleRelease -PappLinkHost=play.myshard.com` bakes that one host
+  into the filter and enables the HTTPS redirect for that host.
+
+### 4.2 Manifest
+
+A second intent-filter on `MainActivity`, alongside the unchanged custom-scheme one:
+
+```xml
+<intent-filter android:autoVerify="true">
+    <action android:name="android.intent.action.VIEW" />
+    <category android:name="android.intent.category.DEFAULT" />
+    <category android:name="android.intent.category.BROWSABLE" />
+    <data android:scheme="https"
+          android:host="${appLinkHost}"
+          android:path="/mobile/callback" />
+</intent-filter>
+```
+
+### 4.3 `SsoAuthManager` (pure Kotlin, unit-tested on the JVM)
+
+- **Redirect selection in `buildStartUrl`:** request the HTTPS `redirect_uri`
+  `https://<pairedHost>/mobile/callback` **iff** `BuildConfig.APP_LINK_HOST` is non-blank *and* equals
+  the paired base-URL host (case-insensitive); otherwise the fixed custom-scheme `REDIRECT_URI`. A
+  white-label build that bakes the host is responsible for enabling the server toggle too (§3.2).
+- **Verified-callback matcher + host-trust check:** a new `matchesAppLinkCallback(scheme, host, path)`
+  accepts only `scheme == https`, `path == /mobile/callback`, and **`host == the paired base-URL host`**.
+  The paired-host equality is defense-in-depth: even though `autoVerify` already means only a real,
+  opted-in shard domain can route here, the app still refuses any HTTPS callback whose host isn't the
+  shard it is currently paired to.
+- The rest is unchanged: both matchers feed the *same* `complete(state, code, error)` → `/exchange` →
+  `SessionManager.onSignedIn`. There is no second auth path.
+
+### 4.4 `MainActivity`
+
+`handleSsoCallback` routes a VIEW intent through **`matchesCallback(...) || matchesAppLinkCallback(...)`**;
+everything downstream (state check, exchange, sign-in) is shared. Custom-scheme and App Link callbacks
+are indistinguishable past the edge.
+
+## 5. Turning it on for a shard
+
+1. Publish/point the app build at the shard host (`-PappLinkHost=<host>`) — or use the generic build and
+   leave App Links off.
+2. Set `MOBILE_APP_CERT_SHA256` (release cert fingerprint) in the website env.
+3. Admin → Shard/Settings: enable **App Links** (`mobile_app_links_enabled`).
+4. Verify `https://<host>/.well-known/assetlinks.json` returns the statement; confirm Android verifies
+   (`adb shell pm get-app-links com.runicgateway.app`).
+
+If any step is skipped the app transparently keeps using the custom scheme — nothing breaks.
+
+## 6. Testing
+
+- **Server (`node --test`):** route 404s when the toggle is off; 404s when on but no fingerprint;
+  returns the correct statement + content-type when on and configured; the redirect allowlist accepts
+  `https://<host>/mobile/callback` only when enabled and rejects it otherwise (custom scheme always
+  accepted).
+- **App (JVM unit tests):** `matchesAppLinkCallback` accepts only https + `/mobile/callback` + the paired
+  host and rejects a foreign host / http / wrong path; `buildStartUrl` requests the HTTPS redirect only
+  when the baked host matches the paired host, else the custom scheme.
+
+## 7. What does *not* change
+
+- The bridge's server design (PKCE Layer A/B, single-use codes, `/start` + `/exchange`) is untouched;
+  App Links are *one more allowlist entry* + *one static file route*. That is the whole point of keeping
+  the allowlist exact-match and configurable from day one.
+- The custom scheme remains on every build and is the permanent fallback.
+- No change to `servuo-plugins/` — App Links are entirely a website ↔ app concern.

+# Android App — Plan
+
+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
+design contract for the `RunicGateway/Android-app` repo. It was written before implementation so the
+API changes it depends on could be landed in `website/` and `docs/` first. The authoritative API
+reference is the committed OpenAPI spec at `website/server/swagger/swagger-output.json` (regenerated
+via `npm run swagger`).
+
+**Build progress (§9):** ✅ **M0 — repo scaffold** (2026-07-19, `RunicGateway/Android-app#2`):
+Gradle 8.7 wrapper + AGP 8.6.1 / Kotlin 2.0.20, JDK 17, minSdk 29 / compile-target 35,
+`applicationId com.runicgateway.app`; a version catalog pinning the full §2 stack; a Compose + Hilt
+single-activity skeleton (externalized strings, adaptive icon); and CI (`pr-checks.yml` →
+`./gradlew lint test assembleDebug`).
+
+✅ **M1 — connect & browse** (2026-07-19, `RunicGateway/Android-app#6`, functional Kotlin pass): the
+first-run base-URL connect flow (probe `GET /public/status`, verify the backend's version identity,
+persist to DataStore; HTTPS-only in release, HTTP allowed in debug; Settings → Server hard reset);
+a runtime-selected base URL via a sentinel-host Retrofit + `HostSelectionInterceptor` (the host is
+**not** compiled in) plus a `UserAgentInterceptor` past the scanner guard (§8); the layered
+`screen → ViewModel → repository → PublicApi → DTO` stack returning a typed `ApiResult`
+(`Ok`/`HttpError`/`NetworkError`) for graceful degradation (§7); brand-seeded Material 3 theming from
+`/public/settings`; and functional Compose screens for Home/Status, News (+ post detail), Wiki
+(+ detail), CMS pages (block renderer: `heading/rich_text/image/quote/cta/divider/two_column`), and
+the contact form, under one declarative navigation drawer (§5). JVM unit tests cover URL
+normalization, host rewriting, `ApiResult`/`UiState` mapping, and brand-color parsing.
+
+> **API-client deviation from §2 (recorded):** DTOs + the Retrofit interface are **hand-written and
+> spec-aligned**, not `openapi-generator` output. The committed `swagger-output.json` is produced by
+> **swagger-autogen**, whose component schemas are meta-descriptive (nested `{type, example}`
+> wrappers) rather than codegen-clean OpenAPI models, so a generator would emit unusable DTOs. The
+> hand-authored client is the "checked-in generated module" §2 already allows; shapes were matched
+> against the website controllers/models and every DTO ignores unknown keys (additive fields are
+> safe). True codegen would first require authoring the spec's component schemas as real OpenAPI
+> models.
+
+✅ **M2 — public shard** (2026-07-19, `RunicGateway/Android-app#7`, functional Kotlin pass): the public
+shard widgets (§6.2) over `/public/shard/*` — a shard hub (connection status, online count, latest
+economy, presence, staff online) plus live boards for champion spawns, guilds, governors (with
+on-demand term history) and falling houses (IDOC) — and the live **SSE** feed. `ShardStreamClient`
+consumes `/public/shard/stream` over OkHttp SSE and, unlike the browser `EventSource`, drives its own
+reconnect/backoff (reset on open, no read timeout for the idle keepalive), so a dropped feed degrades
+to "offline" rather than crashing (§7). Boards seed from a snapshot then merge `*.update` / `*.remove`
+SSE deltas in place via a reusable `LiveBoard`, mirroring the website's merge semantics; DTOs are
+hand-authored + spec-aligned (as recorded for M1) and the live frames decode into the same board
+DTOs. Wired into the shared drawer (§5), all strings externalized (§2). JVM unit tests (28) cover DTO
+/ live-frame decode, the board merge, event-text formatting (parity with `lib/shardEvents.js`), and
+SSE frame parsing. No backend/API change — the app is a pure consumer of the existing public shard
+surface.
+
+✅ **M3 — auth** (2026-07-19, `RunicGateway/Android-app#8`, functional Kotlin pass): native
+**username/password (+ single-request TOTP) login** over the existing `POST /auth/mobile/login` — a
+`401 { totpRequired }` reveals the code field and a wrong code re-lands as a code error; `429` surfaces
+a friendly backoff message (§4.1). The token pair lives in **EncryptedSharedPreferences** (a
+`TokenStore` behind `SessionManager`, the single source of truth for the in-memory bearer + the
+observable `Session`); the base URL stays in plain DataStore (§4.3). An OkHttp `AuthInterceptor`
+attaches the bearer and a `TokenAuthenticator` does a **one-shot, mutex-serialized refresh** on a
+bearer `401` and replays the request — refresh runs on its own **bare** client (no interceptor/
+authenticator) so it can never recurse, rotated single-use tokens are stored atomically, and a dead
+refresh (`401`) signs out while a transient network error keeps the session. Logout
+(`POST /auth/mobile/logout`, this session or all devices) tears down locally even if the call fails.
+`GET /auth/me` **re-validates the role on every resume** (`LifecycleResumeEffect`); a surviving `401`
+signs out, so a server-side demotion drops menu access promptly (role stays advisory — the backend is
+authority, §4.3). The **access-level menu** is one declarative list (`visibleEntries` filters by
+session — public / signed-in / player) with a Sign in / Sign out toggle and a **My Account** screen
+(identity + role + sign-out / sign-out-everywhere). Registration, forgot-password, and SSO are
+**Custom-Tab hand-offs** (androidx.browser) to the website's own pages (`/account/register`,
+`/account/forgot`, `/account/login`) — no native screens (§4.2). The Settings → Server switch now also
+clears the stored session (§3). JVM unit tests (18) cover auth-DTO decode (incl. `totpRequired` vs a
+plain credential `401`), the `SessionManager` lifecycle over a fake store, and the menu access filter
++ role mapping. **No backend/API change** — the app is a pure consumer of the existing mobile bearer +
+`/auth/me` surface.
+
+> **Biometric app-lock — descoped from v1 (decided at M6).** §4.3/§9 flagged an *optional* biometric
+> app-lock, deferred from M3 to M6. At M6 it was **descoped from v1 entirely**: tokens are already
+> encrypted at rest (Tink/AES-256-GCM), so an app-lock is a pure UX convenience, not a security
+> requirement, and it changes no data flow. It is **not** in the first release; revisit only if it
+> becomes a requested feature.
+
+✅ **M4 — player self-service & game data** (2026-07-19, `RunicGateway/Android-app#9`, functional Kotlin
+pass): the signed-in player surface, all as a pure consumer of the existing bearer-gated API.
+**Account self-service** over the role-agnostic `/auth/me/account*` (§6.4) — change username (409
+"taken" surfaced; a success re-validates the session so the shell reflects the new name at once),
+change/set password (the SSO-account "no current password" path from `has_password`), TOTP
+**setup → scan → enable** (the `data:` QR is base64-decoded to a bitmap in-app) / disable-by-code, and
+list/unlink SSO identities — each mutation folding its `ApiResult` into a section-scoped, localized
+banner (§7). **Game-account linking** (§6.3) — the in-game `[link` one-time code (`POST
+/player/shard/link`) plus the hybrid signup (`POST /player/shard/account`, shown only when the public
+`gameAccountSignup` flag is set), and the linked-accounts list. **Own game data**, text-only (§6.3):
+per-account character roster → a character sheet (attributes, vitals, resistances, best-first skills,
+equipment with AOS mods, and guild/governor standing chips — bare cliloc-number titles/item names are
+skipped, as the app ships no cliloc table, matching the website's `CharacterSheet.jsx`); player
+vendors (shops + listings) with recent sales; and the player's own houses (decay/IDOC). Each
+per-account read carries its **own** load state, so a down shard degrades that one account to
+offline/retry (`503`) — or not-found (`403`) — without blocking the rest. The menu gains three
+**PLAYER-access** groups (My Characters / Vendors / Houses) revealed only when the session role is
+`player`; a `PlayerGate` sends a signed-out or server-side-demoted user home. DTOs are hand-authored +
+spec-aligned (as recorded for M1); 17 new JVM unit tests cover the account + player-shard DTO decode
+(hex serials, permissive objects, equipment mods) and the character-sheet title/skill display helpers.
+**No backend/API change** — the `/auth/me/*` and `/player/shard/*` surfaces the app consumes were the
+§8 prerequisites, already landed.
+
+✅ **M5 — design pass** (2026-07-20, `RunicGateway/Android-app#10`): the shard-website theme applied
+across every screen, restyling the working M1–M4 UI with **no architecture, data-flow, endpoint, or DTO
+change** (§2.1). The design was produced in Claude Design (`Runic Gateway Screens.dc.html`) and
+implemented in Compose. Because the functional screens already draw their color/type/shape from
+`MaterialTheme` tokens (§2), the restyle lives mostly in the **theme layer** and propagates: a deep
+blue-black surface stack (page `#0b0f14` / screen `#0e1318` / elevated `#11161d`), a slate-blue accent
+(`#7f99bd`) with a light CTA fill (`#cdd9e8`), parchment serif body copy, and the engraved **Cinzel**
+serif display face (bundled weight-axis variable font, SIL OFL) for headings and the top bar. The app is
+now **dark-only** — the shard-website look is a single dark theme, so the light scheme is dropped and the
+system light/dark setting is ignored; **per-shard brand-accent seeding is retained** (a site's published
+accent still tints the primary/secondary roles, §3). A small set of reusable components — semantic status
+pills, section labels, a gradient "feature" card, and slim stat meters — carries the motifs the design
+repeats (home status, shard-online banner, champ/character/house status, character vitals & skills). The
+launch theme and system bars are darkened so the first frame matches (no white flash). Verified by
+`:app:assembleDebug` + `:app:testDebugUnitTest` (green); an on-device visual pass against the mockup is
+the one open QA item noted on the PR.
+
+✅ **M6 — polish & release mechanics** (2026-07-20, `RunicGateway/Android-app#11`): the release
+plumbing to ship v1 as a signed, sideloadable APK, with **no architecture, data-flow, or endpoint
+change**. **Default brand app icons** — a gateway-medallion adaptive launcher icon (all densities +
+round + Play Store icon) over the deep-indigo brand background (the Image Asset wizard's default
+green grid was replaced, and the legacy square/round bitmaps + 512 Play icon recomposited to match);
+plus an "RG" notification icon staged for M7. A **version-mismatch guard** (§3): the first-run connect
+probe refuses a backend whose API version this build can't speak (a future `v2`) with a clear
+"app out of date" message rather than mis-rendering (lenient on an older backend that omits `api`).
+**Release build hardening** (§7, §12) — R8 full-mode minify + resource shrink (~31 MB debug → ~4 MB
+signed release) with keep-rules for the kotlinx.serialization serializers, the wire DTOs, and the
+Retrofit interfaces; a release `signingConfig` that reads keystore material from a **gitignored**
+`keystore.properties` or env vars (absent → unsigned; the keystore is never committed); and
+`versionName`/`versionCode` overridable via `-P` so a release tag + CI run number drive them (§10).
+**CI `release.yml`** — on a `v*` tag, builds a **signed** APK (keystore decoded from a base64 Gitea
+secret) and attaches it + `SHA256SUMS` to a Gitea release; `workflow_dispatch` is a signing dry run.
+HTTPS-only in release (M1), no token logging (logging is debug-gated, M3), and the Settings → Server
+hard reset (M3) were already in place. Biometric app-lock is **descoped from v1** (see the note below).
+
+**The functional build (M0–M4), design pass (M5), and release mechanics (M6) are complete. Cutting
+the first `v*` release tag (once the signing secrets are set + the on-device QA pass is done) and M7
+push notifications are what remain.**
+
+### M7 plan — push notifications (in progress)
+
+M7 spans three repos, so it ships in **two parts**; the backend contract lands first because the app
+is a pure consumer of it (§8/§11).
+
+**Part 1 — `website/` backend + `docs/` — ✅ LANDED** (2026-07-20, `RunicGateway/website#78` merged
++ docs#20). Additive, v1-only (new tables/routes/compose
+service; no existing response shape changes). Decision: **no ntfy publish token** — publishes go over
+the internal compose network to unguessable per-device topics carrying **content-free tickles**
+(`{ stream, ref }`); the publisher honors an optional `NTFY_PUBLISH_TOKEN` if ever set but requires
+none (keeps §11's zero-interaction promise).
+- **Two event sources, one publisher.** The fan-out is a small transport-agnostic
+  `utils/pushDispatch.js` that both producers call: `utils/shardIngest.js` (`ingest()`, beside the
+  existing `broadcast(event)`) for shard-derived streams, and the admin create-post path for the
+  `news.post` stream (§11 lists news posts as a public stream, but they originate in the website, not
+  the shard feed).
+- **Stream catalog** (`config/notificationStreams.js`): public/opt-in — `news.post`,
+  `server.status`, `idoc.warning`, `champ.start`, `governor.election`; personal/owner-keyed
+  (require a linked game account) — `vendor.sale`, `house.idoc`, `account.login`. `mapShardEvent()`
+  maps event kinds → streams, drawing public streams **only** from the SSE `PUBLIC_KINDS` allowlist;
+  sensitive kinds are never fanned out publicly. Personal events are delivered only to the owning
+  user's devices, resolved via `shardLinks.getByAccount` (same ownership source as `/player/shard/*`).
+- **Tables:** `push_devices` (per-device endpoint) and `notification_subscriptions` (per-user opted-in
+  streams), FK → `users` ON DELETE CASCADE, mirroring `mobile_refresh_tokens`.
+- **Routes** under the role-agnostic self surface (never `/admin`): `POST|GET /auth/me/devices`,
+  `DELETE /auth/me/devices/:id`, `GET /auth/me/notifications/streams` (catalog),
+  `GET|PUT /auth/me/notifications/subscriptions`. All bearer/cookie auth; Swagger regenerated.
+- **SSRF guard (important):** a device `endpoint` is a client-supplied URL the backend POSTs to, so
+  registration and every publish validate it is HTTPS and its origin is in the shard's ntfy
+  allow-set (`NTFY_BASE_URL` / `NTFY_ALLOWED_ORIGINS`), rejecting loopback/private hosts.
+- **ntfy** added to `website/docker-compose.yml` as a pinned upstream image with a committed
+  declarative `./ntfy/server.yml` and named volume, **no published host port** (reached via the
+  reverse proxy; internal-only for the publisher), anonymous read-write to unguessable topics (no
+  per-user accounts — safe because tickles are content-free).
+
+**Part 2 — the Android app — ✅ LANDED** (2026-07-20, `RunicGateway/Android-app#15` + a small
+`RunicGateway/website#79` settings addition + this docs PR). Built exactly to the plan below, with
+two recorded implementation decisions:
+- **Direct-ntfy embedded distributor, no UnifiedPush library (deviation from §2's "UnifiedPush
+  connector" wording — the plan's stated likely path, work item 1).** The app talks straight to ntfy
+  over its own topic rather than pulling in `org.unifiedpush.android:connector` + an external
+  distributor: a foreground `PushService` holds an OkHttp-SSE connection to `<ntfy>/<topic>/sse`
+  (reusing the M2 `ShardStreamClient` reconnect pattern) on a **bare** client, `PushManager`
+  orchestrates topic mint / device register / start-stop keyed to the session, and `PushNotifier`
+  posts a per-stream notification whose tap deep-links via `MainActivity` intent extras. No new Gradle
+  dependency; a `PushResult`/transport seam keeps the future FCM Play flavor cheap. Reasons: the
+  UnifiedPush distributor model assumes a *separate* app (exactly what the user vetoed), we already own
+  the SSE machinery, and this keeps the APK Google-free and dependency-light. New code lives in
+  `core/push/` + `ui/notifications/` + a `NotificationsApi`/`NotificationsRepository`; no existing
+  screen's data flow changed.
+- **One small additive backend field was required after all (`push.ntfyUrl`).** The embedded
+  distributor must know the shard's client-facing ntfy URL to build its topic endpoint, and Part 1
+  never surfaced it (the `NTFY_*` vars are server-only). So `/public/settings` now carries
+  `push: { ntfyUrl }` (from `NTFY_PUBLIC_URL` / first `NTFY_ALLOWED_ORIGINS`; never the internal
+  `NTFY_BASE_URL`), null when unconfigured → the app shows push as unavailable for that shard. This is
+  the "no backend work in Part 2" caveat corrected: it is additive, non-sensitive, and forward-compatible
+  (an older backend omitting it just decodes to null). **Deploy dependency stands:** push only delivers
+  once the shard sets `NTFY_PUBLIC_URL`/`NTFY_ALLOWED_ORIGINS` (§13).
+
+Verified green: `:app:testDebugUnitTest` (18 new JVM tests — notifications DTO decode, ntfy tickle
+parse incl. malformed, topic/URL building, stream→route map + personal gating) + `:app:lintDebug` +
+`:app:assembleDebug`; backend 250 tests (+3 for `push.ntfyUrl`) and `npm run swagger` clean. The
+foreground-service tradeoff (§11) and the POST_NOTIFICATIONS runtime permission are implemented as
+planned; an on-device delivery pass against a live ntfy is the one open QA item.
+
+**Part 2 (original plan) — the Android app.** UnifiedPush receiver + device registration
+against the merged Part-1 contract, a Notifications settings screen, and notification-tap deep-links.
+The app is architected for push from M0 (§11), so this is **additive** — a new feature slice
+(`core/push` + `ui/notifications` + a `DevicesApi`/`NotificationsApi` pair) that touches no existing
+screen's data flow. Everything the app calls already exists and is merged; there is **no backend
+work** in Part 2.
+
+The Part-1 contract the app codes against (verified against the merged `website` source):
+- `POST /auth/me/devices` `{ transport?: 'unifiedpush'|'fcm', endpoint, platform? }` → `201 PushDevice`
+  `{ id, transport, endpoint, platform, createdAt, lastSeenAt }`. Idempotent per `(user, endpoint)`
+  (upsert). `endpoint` **must** be HTTPS on the shard's ntfy allow-set — a private/loopback or
+  off-allowlist origin is rejected `400` (the SSRF guard). Bearer-auth, so registration only happens
+  while signed in.
+- `GET /auth/me/devices` → `PushDevice[]`; `DELETE /auth/me/devices/:id` → `{ ok: true }` (`404` if not
+  the caller's).
+- `GET /auth/me/notifications/streams` → `{ streams: [{ id, label, description, personal,
+  requiresLinkedAccount }] }` — the eight-stream catalog (`news.post`, `server.status`,
+  `idoc.warning`, `champ.start`, `governor.election`; personal `vendor.sale`, `house.idoc`,
+  `account.login`). Render from this, don't hardcode.
+- `GET /auth/me/notifications/subscriptions` → `{ streams: [id…] }`; `PUT` the same shape (full
+  replace; unknown ids dropped server-side; the stored set is echoed back).
+- **The wire tickle** the device receives is the content-free `{ "stream": "<id>", "ref": "<opaque>" }`
+  JSON body (`utils/pushDispatch.js`). `ref` is a serial / city / timestamp hint — **never** content.
+
+Work items:
+
+1. **Transport — the app is its own distributor; no second app (DECIDED).** The Runic Gateway app
+   **embeds its own UnifiedPush distributor**. The self-hosted **ntfy is only the relay server**, never
+   a user-installed app — the user installs *one* APK and it receives its own notifications, with no
+   external distributor (no ntfy app, no NextPush) and no Google Play Services. Concretely, the embedded
+   distributor holds a **persistent connection to the shard's ntfy** in a **foreground service**,
+   reusing the OkHttp reconnect/backoff pattern already built for `core/net/ShardStreamClient` (M2): it
+   subscribes to the app's own random, unguessable ntfy **topic** (over `wss://<ntfy-host>/<topic>/ws`
+   or the `/json` stream) and forwards each received `{stream,ref}` tickle to the app's receiver. The
+   **endpoint the app registers** with the backend (work item 5) is that topic's public URL
+   (`https://<ntfy-host>/<topic>`) — exactly the client-supplied `endpoint` the merged `POST
+   /auth/me/devices` contract expects and the URL the backend POSTs tickles to. Keep the transport
+   behind a small `PushTransport` seam so the **future Play/FCM build flavor** (§11, §M8) can swap the
+   embedded-ntfy distributor for FCM without touching registration, subscriptions, or notification code.
+   (Implementation detail to confirm: whether a maintained Google-free embedded UnifiedPush-distributor
+   library fits, or — more likely — a thin in-app distributor written directly over ntfy's subscribe API
+   reusing `ShardStreamClient`. Either way the distributor lives **inside this app**; the UnifiedPush
+   *receiver* abstraction is retained only to keep the FCM-flavor seam clean.)
+   - **Tradeoff, accepted:** instant background delivery requires a persistent foreground service with
+     an ongoing (low-importance) notification and its battery cost — this is exactly how ntfy's own app
+     does instant delivery, and it is the price of Google-free self-delivery. A future "battery saver"
+     option could fall back to periodic polling, but v1 ships the always-connected foreground service.
+2. **Deps + manifest.** Add the UnifiedPush connector + the embedded-distributor transport (per #1) to
+   the version catalog; declare `POST_NOTIFICATIONS` (API 33+ runtime permission) **and
+   `FOREGROUND_SERVICE` + `FOREGROUND_SERVICE_DATA_SYNC`** (API 34+, for the persistent ntfy
+   connection); register the receiver and the foreground service in `AndroidManifest.xml`; define the
+   notification channels (id/name externalized, §2) — one for real notifications plus a low-importance
+   channel for the ongoing foreground-service notification — and reuse the "RG" notification icon
+   **already staged in M6**.
+3. **`core/push` — embedded distributor + receiver.** The **distributor** component is a foreground
+   service that owns the ntfy connection (per #1): it (re)creates the app's topic, subscribes over
+   OkHttp with reconnect/backoff cloned from `ShardStreamClient`, and forwards each frame to the
+   receiver. The **receiver** parses the `{ stream, ref }` tickle (`kotlinx.serialization`; an
+   unknown/garbled body is dropped, not crashed — §7 discipline) and posts a notification (work item 7).
+   Endpoint (re)registration against the backend fires on first subscribe / topic (re)creation
+   (work item 5); a transient ntfy drop is just a reconnect, not a re-register.
+4. **`DevicesApi` + `NotificationsApi` (Retrofit) + DTOs.** Hand-authored, spec-aligned (as recorded
+   for M1): `RegisterDeviceRequestDto`, `PushDeviceDto`, `NotificationStreamDto`,
+   `NotificationStreamsDto`, `NotificationSubscriptionsDto`. Both go through the existing bearer/refresh
+   stack (`AuthInterceptor` + `TokenAuthenticator`) and return the typed `ApiResult` (§7). A
+   `NotificationsRepository` owns register/list/delete-device and get/put streams+subscriptions.
+5. **Endpoint ↔ backend lifecycle (mirror the M3 token teardown).** Persist the app's ntfy topic, its
+   endpoint URL, and the returned device `id` in prefs (DataStore; the topic/endpoint isn't a secret —
+   its security rests on being unguessable + the content-free tickle, §11). Start the embedded
+   distributor and `POST /auth/me/devices` **only when the user has ≥1 subscription and is signed in**.
+   On **logout / dead-refresh sign-out / Settings→Server switch**, `DELETE /auth/me/devices/:id`, **stop
+   the foreground service**, and drop the topic — wire this into `SessionManager` beside the existing
+   token-clear so a signed-out device stops receiving (§4.3, §11 "unregister on logout / token
+   revocation"). On a **server (base-URL) switch**, mint a fresh topic against the new shard's ntfy (the
+   old endpoint's origin won't be on the new host's allow-set). Re-assert the endpoint + restart the
+   service on app start when signed-in + subscribed. A `400` on register (endpoint origin off the
+   shard's `NTFY_ALLOWED_ORIGINS`) surfaces a clear "your shard's push relay isn't reachable" state, not
+   a crash.
+6. **Notifications settings screen (`ui/notifications`).** Lists the catalog from
+   `GET …/streams` with a per-stream toggle bound to `GET/PUT …/subscriptions`; a **personal** stream
+   (`requiresLinkedAccount`) is greyed with a "link a game account" hint until the user has a linked
+   account — reuse the linked-accounts signal already fetched for M4's player surface
+   (`PlayerShardRepository`), not a fresh source of truth. Toggling to a non-empty set triggers the
+   register flow (#5) and requests `POST_NOTIFICATIONS`; emptying the set unregisters. Each mutation
+   folds its `ApiResult` into a section-scoped, localized banner (§7 parity with M4).
+7. **Deep-links (resolves the §13 open item).** Tapping a notification opens the app to the stream's
+   home: `news.post`→News, `server.status`/`champ.start`/`idoc.warning`/`governor.election`→Shard,
+   `vendor.sale`→Vendors, `house.idoc`→My Houses, `account.login`→My Account. Routed through the
+   existing `ui/navigation/Routes.kt`; a signed-out/deep-link-to-player tap lands on the `PlayerGate`
+   (M4) rather than erroring. **v1 shows a generic per-stream notification** (localized catalog
+   `label`) and deep-links — it does **not** pull `ref` content first; the content-free design means
+   nothing needs decrypting to render the tap, and the target screen fetches fresh over the
+   authenticated API on open. (Pulling `ref` for a richer inline notification is a possible later
+   enhancement, not v1.)
+8. **Menu.** Add a **Notifications** entry to the signed-in group in `ui/navigation/Menu.kt` (near My
+   Account), visible once signed in.
+9. **Permission UX.** Request `POST_NOTIFICATIONS` at the moment the user first enables a stream (API
+   33+); on denial, keep the toggle off and show how to enable it in system settings — never nag on
+   launch.
+10. **Tests (JVM, `testDebugUnitTest`).** DTO decode (device/stream/subscription), `{ stream, ref }`
+    tickle parse (incl. a malformed body → dropped), the stream→deep-link map, the "personal greyed
+    until linked" gate, and the register/unregister lifecycle over a fake `SessionManager` + repository
+    (parity with M3's session tests).
+
+**Cross-repo dependency to confirm before/at implementation** (a Part-1 §13 open item): the shard's
+finalized **ntfy reverse-proxy hostname** must be in `NTFY_ALLOWED_ORIGINS`, because the distributor
+hands the app an endpoint on *that* origin and the backend rejects a register whose origin isn't
+allow-listed. This is deployment config, not code, but Part 2 can't be end-to-end tested until it's
+pinned. No `website`/`link`/`servuo-plugins` code change is expected in Part 2.
+
+Ships as `RunicGateway/Android-app#15`; bumps `versionCode`/`versionName` for a post-v1 release
+(§10). Like M1–M4 it records itself in the §9 build-progress block on landing.
+
+### M9 plan — native SSO login (in progress)
+
+M9 spans `website/` + `android-app/` + `docs/`, so — like M7 — it ships in **two parts**, backend
+first (the app is a pure consumer of the bridge contract; §4.2, §9 item 10).
+
+**Part 1 — `website/` backend + `docs/` — ✅ LANDED** (the Mobile SSO Authorization Bridge:
+`mobile_auth_sessions`/`mobile_auth_codes` tables, `GET /auth/mobile/sso/start`, the `mode:'mobile'`
+branch in the reused SSO callback + TOTP completion, `POST /auth/mobile/sso/exchange`, the exact-match
+`MOBILE_AUTH_REDIRECT_URIS` allowlist, and bridge-table cleanup). Canonical ref:
+`../website/BACKEND_DESIGN.md` → "Mobile SSO Authorization Bridge".
+
+**Part 2 — the Android app (this milestone).** The native in-app "Sign in with Google / Discord"
+client. **Additive** — a new auth slice (`core/auth/sso` + a `SsoApi`/`SsoAuthManager` + a login-screen
+provider list) that feeds the *existing* M3 session machinery; it adds **no** new token-storage or
+refresh code, and touches no other screen. **No backend work** — every endpoint it calls is merged.
+
+The Part-1 contract the app codes against (verified against the merged `website` source):
+- `GET /auth/providers` → `[{ id, name, icon, loginUrl, priority }]` (public discovery, no secrets).
+  `icon` ∈ `google|discord|oidc|oauth2`. Render the provider buttons from this — don't hardcode.
+- `GET /auth/mobile/sso/start?provider&code_challenge&state&redirect_uri` — **opened in a Custom Tab**
+  (not an XHR): it 302s through the IdP and finally deep-links back to `redirect_uri`. `redirect_uri`
+  must be an **exact** allowlist entry — the app always sends the one fixed callback
+  `runicgateway://auth/callback`.
+- The callback deep link carries **either** `?code=<one-time>&state=<echoed>` (success) **or**
+  `?error=<reason>&state=<echoed>` (`invalid_provider`/`provider_unavailable`/`server_error`, or an
+  IdP/link refusal) — **never a token**.
+- `POST /auth/mobile/sso/exchange` `{ code, code_verifier }` → the **same** `{ accessToken,
+  refreshToken, expiresIn, user }` pair as `/auth/mobile/login`; `401` on an unknown/expired/used code
+  or a PKCE-verifier mismatch.
+
+Work items:
+
+1. **PKCE + state (Layer B, app↔website).** A pure-JVM `Pkce` helper (unit-testable, no Android
+   framework types): `code_verifier` = 32 random bytes base64url (RFC 7636 S256), `code_challenge` =
+   base64url(SHA-256(verifier)), plus a random `state`. `java.util.Base64` URL encoder without padding
+   + `MessageDigest` — matches the backend's `crypto.createHash('sha256')…base64url` exactly.
+2. **`SsoAuthManager` (Singleton) — the flow orchestrator.** Holds the **pending** `{state, verifier}`
+   in memory (lost on process death → the exchange fails closed and the user retries; acceptable and
+   safe, documented). `buildStartUrl(provider)` mints PKCE+state, stashes pending, and builds the
+   absolute `/start` URL off `BaseUrlHolder` for the Custom Tab. `isCallback(uri)` matches our scheme;
+   `complete(uri)` verifies `state` (CSRF), maps an `error`, exchanges the `code` with the stashed
+   `verifier`, and on success drives `SessionManager.onSignedIn` — the *same* entry the password login
+   uses, so push registration (`PushManager` observes the session) and the menu react identically. It
+   exposes an `outcome: StateFlow` (Idle/Success/Failed(reason)) the login screen consumes, robust to a
+   ViewModel/activity recreation while the Custom Tab is foreground.
+3. **`SsoApi` + DTOs.** `GET api/v1/auth/providers` → `List<SsoProviderDto>`; `POST
+   api/v1/auth/mobile/sso/exchange` tagged `Http.NO_SESSION_HEADER` (no bearer; a credential-style
+   `401` must not be read as an expired session or trip the refresh `Authenticator`) → the reused
+   `MobileTokenResponse`. Lenient Json (additive fields safe, §8).
+4. **Deep link.** Register the `runicgateway://auth/callback` intent-filter on `MainActivity`
+   (`VIEW` + `DEFAULT` + `BROWSABLE`, `scheme/host/path` from one shared constant) and set
+   `launchMode="singleTop"` so the returning Custom Tab reuses the running task; `onCreate`/`onNewIntent`
+   route a matching `ACTION_VIEW` intent to `SsoAuthManager.complete` on `lifecycleScope`. Custom scheme
+   only for now — App Links deferred (`APP_LINKS.md`).
+5. **Login screen.** Replace the single "SSO on the website" hand-off with a native provider list from
+   `GET /auth/providers`: one button per provider (Google/Discord/OIDC glyph from `icon`), each opening
+   its `/start` URL in a Custom Tab via the existing `WebHandoff`. The `LoginViewModel` collects
+   `SsoAuthManager.outcome` → a success pops back like a password sign-in; a failure surfaces a friendly
+   inline error (reusing the existing `LoginError` channel + a new SSO string). Falls back to the
+   website login hand-off when discovery returns no providers or the base URL is unset.
+6. **Tests (JVM, `testDebugUnitTest`).** `Pkce` (verifier charset/length, challenge = base64url-SHA-256
+   of a known vector, no padding), start-URL building (encoded params, fixed `redirect_uri`), and
+   `SsoAuthManager.complete` over a fake `SsoApi` + `SessionManager`: success signs in; a mismatched or
+   missing `state` fails without exchanging; an `error=` callback maps to the right reason; a `401`
+   exchange maps to expired-code; a missing pending (process death) fails closed.
+
+Ships as a `RunicGateway/Android-app` PR; bumps `versionCode`/`versionName` for a post-v1 release
+(§10) and records itself in the §9 build-progress block on landing. No `website`/`link`/`servuo-plugins`
+code change is expected in Part 2.
+
+**Prerequisite progress (§8):** all v1 prerequisites are **done** (2026-07-19) — ✅ password reset
+(item 2; website#75 + docs#8), ✅ role-agnostic `/auth/me/*` self surface (item 1; website#76 + docs#10),
+✅ version/health surfacing (item 4) and ✅ branding for mobile (item 6). **Push notifications (item 3)
+is the only remaining §8 work and is post-v1 (M7).** The app's functional Kotlin pass (M0–M4) is now
+unblocked.
+
+The workspace already holds `website/`, `link/`, `servuo-plugins/`, and `docs/`. `android-app/` is
+the fifth repo. It is **purely an API client of the website backend** — it never talks to the
+`link/` sidecar or the shard directly, and it ships none of the shard/sidecar wiring.
+
+---
+
+## 1. Purpose & scope
+
+A native Android client for a Runic Gateway shard's public site + player self-service. It surfaces
+the same content and player features as `website/client`, minus every administrative/management
+console. It is a **read + self-service** app, not an operator tool.
+
+### In scope
+- **Public content** (no auth): news / Five-on-Friday / newsletter / screenshots, wiki, CMS pages,
+  site status & maintenance page, contact form.
+- **Public shard widgets** (no auth): shard status, online staff, live event feed, economy series,
+  champion spawns, guilds, governors, houses/IDOC, presence — including the live **SSE** stream.
+- **Account & auth** (bearer token): native **username/password login (with TOTP 2FA)**, logout,
+  refresh; account self-service (change username/password, TOTP enroll/disable, list/unlink SSO
+  identities). Registration, invite acceptance, password reset, and SSO are **website-handled** — the
+  app hands off to the website's pages for those (§4.2), not native screens.
+- **Player's own shard/game data** (bearer token): link a game account via a `[link` one-time code,
+  hybrid game-account signup, list linked accounts, own character roster, character sheet, own
+  player vendors, own vendor sales, own houses (home/decay status).
+- **Access-level menu**: one shared navigation that reveals items based on the signed-in user's role.
+- **Opt-in push notifications** (post-v1; architected for from the start): per-stream subscriptions the
+  user chooses — nothing is pushed unless subscribed. See §11.
+
+### Explicitly OUT of scope (never in the app, for any role)
+- The **hero editor** and any CMS authoring/block editing.
+- The **admin / auth-management console** — user management, invites issuance, SSO provider config,
+  moderation console, email config, bot-activity/ban console. (Players still *log in*; what's
+  excluded is the management surface, not authentication itself.)
+- The **Discord bot** management (and anything under the unpublished `/internal/**` port — it
+  returns the decrypted bot token and must never be reachable from a client).
+- **Shard / uo-link administration** — sidecar base-URL/token config (`uoLinkConfig`), shard ops,
+  the staff shard-user console. (The app shows *public* shard widgets and a player's *own* game
+  data; it does not manage the sidecar.)
+
+> The excluded surfaces all live under `/api/v1/admin/**` and `/api/v1/internal/**`. The app only
+> ever calls `/api/v1/public/**`, `/api/v1/auth/**` (incl. the new role-agnostic self surface
+> `/auth/me/*`, §6.4), and `/api/v1/player/**` — it never references `/admin`.
+
+---
+
+## 2. Architecture & stack
+
+Native, Android-only:
+
+| Concern | Choice |
+|---|---|
+| Language / UI | **Kotlin + Jetpack Compose** (Material 3) |
+| Navigation | Navigation-Compose, single-activity |
+| HTTP | **Retrofit + OkHttp**, `kotlinx.serialization` converter |
+| Async | Coroutines + Flow; `viewModelScope` |
+| DI | Hilt |
+| Saved base URL / prefs | **Jetpack DataStore** (Preferences) |
+| Tokens at rest | **EncryptedSharedPreferences** (Jetpack Security / Tink-backed) |
+| Live feed | OkHttp SSE (`EventSource`) for `/public/shard/stream` |
+| Images | Coil |
+| Min SDK | **Android 10 (API 29)** — ~95% device reach with a modern baseline (biometric, storage, TLS) and no compat shims |
+| Target/compile SDK | Latest stable (35) |
+| Telemetry | **None in v1** — no crash/analytics SDK (privacy-first). Revisit self-hosted crash reporting later. |
+| Localization | **Strings externalized from day one** (`res/values/strings.xml`); English is the only bundled locale, but the structure invites community translations. No hardcoded UI strings. |
+| Web hand-off | Chrome Custom Tabs — opens the website for registration / invite / password reset / SSO (§4.2) |
+
+**API model generation.** The DTOs and the Retrofit interface are generated from
+`swagger-output.json` (OpenAPI 3.0) rather than hand-written, so the client stays in lockstep with
+the backend contract. A build step (or a checked-in generated module regenerated on contract change)
+runs `openapi-generator` against the committed spec. Endpoints that return
+`additionalProperties: true` (several shard reads) are typed as permissive maps / JsonElement.
+
+**Layering** mirrors the backend's discipline: `screen (Compose) → ViewModel → repository → API
+service (Retrofit) → DTO`. Repositories expose `Result`-like sealed types so the UI degrades
+gracefully (see §7).
+
+### 2.1 Build workflow: Kotlin first, then design-led UI
+The app is built in two passes. **First**, the functional Kotlin is written — the layering above with
+placeholder/functional Compose screens: navigation, ViewModels, repositories, the generated API
+client, auth/token handling, and every screen wired to its endpoints and working end-to-end. **Then**,
+once that Kotlin code is done, **Claude Design produces the front-end design** for the app, and
+**Claude Code implements the final UI (Compose screens, theming, components) according to that
+design.** The design pass restyles and refines the already-working screens; it does not change the
+architecture, data flow, or endpoint contracts established in the first pass. Keeping strings
+externalized and branding data-driven (§2, §3) from the start is what lets the design pass reskin
+freely without touching logic.
+
+---
+
+## 3. Base URL: first-run + settings
+
+The app is **brandable to any shard's site** (one site per install), so the API host is not
+compiled in.
+
+- **First run (before init):** a mandatory **"Connect to your shard's website"** screen asks for the
+  site base URL. The app validates it by calling `GET /api/v1/public/status` (and reads
+  `/public/settings` for branding: name/colors/logo). Only on a successful, well-formed response is
+  the URL persisted to DataStore and the app allowed to initialize its main UI.
+  - Accept `https://host[/base]`; normalize/trim; require HTTPS in release builds (allow HTTP only in
+    debug for local dev against `127.0.0.1:3000`).
+  - Failure states: unreachable, non-2xx, not-a-Runic-Gateway-site (missing expected `/public/status`
+    shape), TLS error — each gets a clear retry message. Nothing else in the app runs until this
+    succeeds.
+- **Settings:** the base URL is editable later under **Settings → Server**. Changing it is a
+  hard reset of session state: clear stored tokens, drop cached content, re-run the validation probe,
+  and return to a signed-out state against the new host.
+- **Version guard:** the backend is versioned; surface a clear "app/site version mismatch" state if a
+  future protocol/version header disagrees, rather than mis-rendering.
+
+---
+
+## 4. Authentication & token handling
+
+**Design rule (decided): credential/identity flows live on the website, not in the app.** The app
+implements **only native username/password (+TOTP) login**. Registration, invite acceptance,
+forgot/reset password, and SSO all **run through the website's API + web front end** — the app hands
+off to the website in a browser (Chrome Custom Tab) and the user returns to sign in. This keeps every
+account-provisioning, OAuth, and password path in one audited place rather than duplicated (and
+security-reviewed twice), and it means **no new mobile-facing auth endpoints** are required for v1.
+Password reset is being built on the backend + web front end **before** app work begins (§8), so it is
+simply available in that hand-off, not app scope.
+
+### 4.1 Username + password (+ TOTP) — the app's only native auth, ready today
+Uses the existing **mobile bearer** surface, no backend changes:
+
+- `POST /auth/mobile/login` `{ username, password, code? }` →
+  `{ accessToken, refreshToken, expiresIn, user: { id, username, role } }`.
+  - **Single-request 2FA:** a `401 { totpRequired: true }` means re-submit with `code`. The login
+    screen reveals a code field on that response.
+  - Respect `429` (backoff / rate-limit) with a friendly "try again shortly" state — login is guarded
+    by per-IP backoff → slow-down → hard cap on the server.
+- `POST /auth/mobile/refresh` `{ refreshToken }` → new pair. **Refresh tokens are single-use and
+  rotated**: store the new pair atomically; a failed refresh (401) means the session is dead → sign
+  out and return to login. An OkHttp `Authenticator`/interceptor performs a one-shot refresh on a
+  `401` from a bearer call, with a mutex so concurrent 401s trigger only one refresh.
+- `POST /auth/mobile/logout` `{ refreshToken?, all? }` (requires bearer) — revoke this session or all
+  sessions. Called on user logout and on "sign out everywhere."
+### 4.2 Website-handled flows: registration, invite, forgot-password, SSO
+These are **not** rebuilt in the app. The app links out to the website's own pages/API and the user
+completes them in a Custom Tab, then returns and signs in natively (§4.1):
+- **Register / accept invite** — the app opens the website's register / `…/invite/:token` pages. Invite
+  emails already link to the website. After the account exists, the user signs into the app with their
+  new username + password. (No mobile register/invite endpoints needed.)
+- **Forgot / reset password** — the app links to the website's reset page (the flow being built in §8
+  before app work). The user resets there, then signs into the app. (No mobile reset endpoint needed.)
+- **SSO (Google / Discord / OIDC)** — **v1** shipped this as a website browser hand-off: an SSO user
+  links their identity and sets a password on the website, then uses password login in the app.
+  `GET /auth/providers` is shown so the login screen can direct users to "sign in with … on the website."
+  - **Native in-app SSO — now being built (M9), post-v1 additive.** The "possible later enhancement"
+    noted here is now the **Mobile SSO Authorization Bridge**: a Custom-Tab flow that hands a one-time
+    code back to the app's fixed callback (`runicgateway://auth/callback`), exchanged for the *existing*
+    mobile bearer tokens. It **extends** the existing `/auth/sso/*` redirect flow rather than adding a
+    parallel auth path — same PKCE-vs-IdP, same link-only + opt-in-provisioning policy, same TOTP gate,
+    same token shape as `/auth/mobile/login`. The bridge adds a **second** PKCE layer (app ↔ website)
+    and an app-generated `state` (CSRF, verified by the app before exchange). Backend + docs land first
+    (this document's canonical API ref is `../website/BACKEND_DESIGN.md` → "Mobile SSO Authorization
+    Bridge"); the native app client is M9. Custom-scheme callback only for now — App Links are deferred
+    (see [`APP_LINKS.md`](./APP_LINKS.md)).
+
+### 4.3 Session model (all paths)
+- **Refresh:** `POST /auth/mobile/refresh` `{ refreshToken }` → new pair. **Single-use / rotated:** store
+  the new pair atomically; a failed refresh (401) means the session is dead → sign out. An OkHttp
+  `Authenticator` does a one-shot refresh on a bearer `401`, behind a mutex so concurrent 401s trigger
+  only one refresh.
+- **Logout:** `POST /auth/mobile/logout` `{ refreshToken?, all? }` (requires bearer) — this session or
+  all sessions ("sign out everywhere").
+- **Storage:** access + refresh tokens live in EncryptedSharedPreferences, never in plain prefs/logs.
+  The base URL may live in plain DataStore; tokens must not. An optional **biometric app-lock** was
+  considered here but **descoped from v1** (tokens are already encrypted at rest; see the M3 note).
+- **Role for the menu** comes from the login response `user.role` and is re-validated via
+  `GET /auth/me` on app resume (roles can change server-side; admin access is re-checked every
+  request on the backend, so the app treats role as *advisory for menu rendering* and lets the server
+  be the authority — a 403 is handled gracefully, never assumed-away).
+
+---
+
+## 5. Navigation — one shared, access-level menu
+
+A **single** navigation definition; each entry declares the minimum access it requires, and the menu
+renders only the entries the current session satisfies. Roles: `anonymous` < `player` /
+`moderator` / `editor` / `admin` (the three staff roles are not a strict ladder — gate by capability,
+not rank).
+
+| Menu group | Visible to | Backing endpoints |
+|---|---|---|
+| Home / Status | everyone | `/public/status`, `/public/settings` |
+| News & content | everyone | `/public/posts/:category`, `/public/pages/:slug` |
+| Wiki | everyone | `/public/wiki`, `/public/wiki/categories`, `/public/wiki/tags`, `/public/wiki/:slug` |
+| Shard (live) | everyone | `/public/shard/*` + `/public/shard/stream` (SSE) |
+| Contact | everyone | `/public/contact` |
+| **My Account** | signed-in | `/player/account/*` (or `/admin/account/*` for staff — see §6.4) |
+| **My Characters / Vendors / Houses** | `player` (linked) | `/player/shard/*` |
+| Sign in / Sign out | toggles on session | `/auth/mobile/*` |
+
+Guidelines:
+- The menu is **declarative + data-driven**, not a pile of `if role ==` checks — one list of entries
+  with a `minAccess`/`requiredCapability` field, filtered by the session.
+- Never hide the fact that more exists behind auth in a way that misleads; anonymous users see public
+  groups and a "Sign in" affordance.
+- The server is the source of truth: a hidden/greyed item is a UX convenience; every gated call still
+  enforces on the backend and the app handles 401/403 cleanly.
+
+---
+
+## 6. Screen ↔ endpoint map
+
+### 6.1 Public content
+- **Home/Status** — `GET /public/status`, `GET /public/settings` (branding + maintenance banner).
+- **News hub** — `GET /public/posts/:category` (`news | five-on-friday | newsletter | screenshots`),
+  detail via `GET /public/posts/:category/:idOrSlug`.
+- **CMS pages** — `GET /public/pages/:slug` (block-based; render the block types the site uses).
+- **Wiki** — list/categories/tags/detail as above.
+- **Contact** — `POST /public/contact` (rate-limited; handle 429/502).
+
+### 6.2 Public shard (live)
+- Status/online/feed/economy/champs/guilds/governors(+history)/presence/houses/idoc — the
+  `/public/shard/*` GETs.
+- **Live updates** — subscribe to `GET /public/shard/stream` (SSE, safe kinds only) and patch the
+  in-memory boards in place (champ/guild/city/house/presence update+remove frames). Reconnect with
+  backoff; fall back to poll if SSE drops.
+
+### 6.3 Player self-service & game data (bearer)
+- **Account** — `GET /player/account`; `PATCH /player/account/username`;
+  `PATCH /player/account/password`; TOTP `setup`/`enable`/`disable`; identities `GET` / `DELETE`.
+- **Game account linking** — `POST /player/shard/link` (one-time `[link` code),
+  `POST /player/shard/account` (hybrid signup, when enabled), `GET /player/shard/accounts`.
+- **My game data** — `GET /player/shard/roster/:account`, `/char/:serial`, `/vendors/:account`,
+  `/sales`, `/houses`. All ownership-checked server-side; a `503` means shard/sidecar down → show an
+  "offline, retry" state (see §7).
+- **Presentation is text-only for v1.** Character sheets and vendor listings render as data/text — no
+  item icons or paperdoll art. A richer "pretty paperdoll" view is a **future** enhancement (pending the
+  art/asset work on the platform side) and is explicitly out of the first release.
+
+### 6.4 Self-service is role-agnostic under `/auth/**` (decided)
+Player self-service is under `/player/account/*` (gated to `role='player'`) and staff use the *same*
+handlers under `/admin/account/*`. Rather than have the app branch by role (and touch `/admin`), we
+**add a role-agnostic self surface under `/auth/**`** — the canonical "me" endpoints for every role.
+The app calls these regardless of role, and never references `/admin`. This is an **additive v1**
+change (see §8): the existing `/player/account/*` and `/admin/account/*` routes stay for web
+back-compat; `/auth/me/*` reuses the same `account.controller` handlers behind `requireAuth` (any
+authenticated role), so there's no logic duplication.
+
+---
+
+## 7. Degradation & offline
+
+Mirrors the website's "degrade gracefully" invariant:
+- Every repository call returns a typed result (`Ok`/`HttpError(status)`/`NetworkError`); the UI never
+  crashes on a down backend or shard.
+- **Shard down** (`503` from shard reads, or `/public/shard/status` shows disconnected) → render the
+  shard as **offline**, keep the rest of the app usable.
+- **Site maintenance** (`/public/status` = maintenance) → show the maintenance page; public shard
+  widgets may still render (they're not maintenance-gated server-side).
+- **Offline caching is not a v1 requirement** (decided). The app assumes connectivity and shows clean
+  loading/error/retry states; it does **not** ship a Room cache in v1. Cached read-only content can be
+  added later without reworking the repository layer (its typed results already isolate the UI from the
+  data source). No `Room` dependency in the initial build.
+
+---
+
+## 8. Cross-repo work to do *before* coding the app
+
+The bridge repos are contracts; the app adds a new consumer. Land these first (in `website/` +
+`docs/`), each with regenerated Swagger.
+
+**Already verified — no change needed** (checked against the current backend):
+- **CORS / native reachability.** CORS is only enabled when `CLIENT_ORIGIN` is set (local Vite dev);
+  in prod the SPA is same-origin and CORS is off. A native HTTP client is not browser-origin-bound, so
+  no CORS/preflight applies. *Caveat:* `app.js` mounts a bot/scanner guard before routing — the app
+  must send a sane `User-Agent` so it isn't caught by scanner heuristics.
+- **`GET /auth/me` bearer support.** `auth/token.js:extractToken` reads the cookie *then* falls back to
+  `Authorization: Bearer`, and `/auth/me` advertises both auth schemes. It returns the current user for
+  a bearer token today. The entire `/player/**` and self-service surface works with bearer as-is.
+- **Token lifetimes.** Access `MOBILE_ACCESS_TTL` = 15m default; refresh `MOBILE_REFRESH_TTL_DAYS` =
+  30 days. The login/refresh response's `expiresIn` reflects the access TTL — drive proactive refresh
+  off it.
+
+**API versioning: everything below stays in v1 (decided).** These are all *additive* routes — new
+endpoints that change no existing response shape — so they do **not** warrant a v2. A v2 API is only
+justified by a breaking change to a contract existing clients depend on, which none of this is. The
+web client and the app both consume v1; a second parallel route tree + Swagger spec would be pure
+maintenance cost. Reserve v2 for a real breaking re-shape if one ever arises.
+
+**To build (all additive, v1):**
+1. **Role-agnostic self-service under `/auth/**` (§6.4, decided).**
+   ✅ **DONE (2026-07-19, RunicGateway/website#76 (+ this docs PR)).** A `me.routes.js`
+   sub-router mounts the existing `account.controller` self handlers behind `requireAuth` (any role) at
+   `/auth/me/*`, so the app has one self surface and never touches `/admin`. The old
+   `/player/account/*` + `/admin/account/*` routes stay for web back-compat. Shipped routes:
+   - `GET /auth/me` — current `{ id, username, role }` (already existed; the app's role source).
+   - `GET /auth/me/account` — full self account.
+   - `PATCH /auth/me/account/username`, `PATCH /auth/me/account/password`.
+   - `POST /auth/me/account/totp/setup|enable|disable`.
+   - `GET /auth/me/account/identities`, `DELETE /auth/me/account/identities/:provider`.
+   - Swagger regenerated with `#swagger` annotations; `test/authMe.test.js` guards the auth gate; and
+     an end-to-end smoketest confirmed both a player and an editor (staff) drive the same surface.
+2. **Password reset — build on backend + web front end FIRST (a prerequisite, not app scope).**
+   ✅ **DONE (2026-07-19, RunicGateway/website#75 + docs#8).** Full platform flow shipped in `website/`:
+   request-reset (`POST /auth/password/forgot`, always a generic 200 — no account enumeration) emails a
+   single-use, ~1h link → reset page + endpoints (`GET|POST /auth/password/reset/:token`) that verify,
+   set the password, and revoke every session (web cutoff + mobile refresh tokens). The token is an
+   opaque random value stored as a **sha256 hash** in a new `password_resets` table (mirroring
+   `user_invites` — chosen over a signed JWT to match the house pattern; functionally equivalent). It
+   also serves SSO-only accounts (null hash) as their set-initial-password path. Swagger regenerated;
+   documented in `BACKEND_DESIGN.md`. The app just links users to the web page (§4.2) — **no mobile reset
+   endpoint.**
+   - No mobile SSO/invite/register endpoints are needed: SSO, registration, and invite acceptance all
+     stay website-handled and the app hands off to them (§4.2). This is a deliberate scope reduction.
+3. **Push notifications** — see §11. Additive v1 endpoints under `/auth/me/devices*` and
+   `/auth/me/notifications*`, plus a **self-hosted `ntfy` service added to `website/docker-compose.yml`**
+   with fully declarative, zero-interaction config. Not required for the first release (M7, not M1–M6).
+   ✅ **Backend + docs LANDED (2026-07-20, RunicGateway/website#78 merged (+ docs#20)).** The
+   contract Part 1 is built: the two tables, the stream catalog + `PUBLIC_KINDS`-gated event mapping,
+   the content-free-tickle fan-out (`utils/pushDispatch`, SSRF-guarded endpoints, owner-keyed personal
+   streams), the six `/auth/me/*` routes (Swagger regenerated), and the declarative `ntfy` compose
+   service (247 server tests green). The app (Part 2, §9 M7) consumes this next — see the "M7 plan"
+   block for the detailed Part 2 plan.
+4. **Version/health surfacing.**
+   ✅ **DONE (2026-07-19, RunicGateway/website#77 (+ this docs PR)).** A dependency-free
+   `config/version.js` (`{ service:'runic-gateway', api:'v1', server:<pkg> }`) is surfaced on
+   `GET /public/status` (so the first-run probe recognizes the backend + reads its version in one call)
+   and on a new **DB-free `GET /public/version`** (canonical target for the version-mismatch guard +
+   a cheap liveness check). Swagger: `PublicVersion` schema. `test/publicVersion.test.js` covers both.
+5. **Docs** — update `docs/website/BACKEND_DESIGN.md` for any new/changed endpoint; keep this file and
+   the OpenAPI spec current. (The workspace `CLAUDE.md` is a **local, uncommitted** file — update it in
+   place as repos come online, but it is never committed.)
+6. **Branding for mobile.**
+   ✅ **DONE (2026-07-19, RunicGateway/website#77 (+ this docs PR)).** Confirmed
+   `GET /public/settings` returns the per-shard `brand` block (name, `accent` color, logo/hero/favicon,
+   plus shortName/tagline/description/url/contactEmail) sourced from `BRAND_*` with admin
+   `site_title`/`contact_email` overrides — the app themes itself from it. Made it first-class in the
+   OpenAPI contract (`Brand` + `PublicSettings` schemas) so the app's codegen gets typed branding
+   instead of an untyped map; `test/publicBrand.test.js` locks the contract. Asset fields may be
+   site-relative paths — the app resolves them against its stored base URL.
+
+No `link/` or `servuo-plugins/` changes are expected — the app is downstream of the website only.
+
+---
+
+## 9. Milestones
+
+**Two passes (§2.1).** M0–M4 were the **functional Kotlin pass** — every screen wired to its endpoints
+and working end-to-end with placeholder/functional Compose UI, no design investment yet. **M5 was the
+design pass**: with the functional Kotlin done, Claude Design produced the front-end design and Claude
+Code implemented the final UI to it. **Both passes are now complete** (M0–M5 landed); polish/release,
+push, and Play (M6–M8) follow the designed app.
+
+1. **M0 — Repo scaffold**: Gradle + Compose + Hilt skeleton, CI (build + lint + unit test), license
+   headers (GPL-3.0-or-later), CONTRIBUTING/AI-disclosure parity with the other repos.
+2. **M1 — Connect & browse** *(functional pass)*: first-run base-URL flow,
+   `/public/status`+`/public/settings` theming, generated API client, public content
+   (news/wiki/pages) + contact. No auth yet.
+3. **M2 — Public shard** *(functional pass)*: shard widgets + SSE live stream with
+   reconnect/degradation.
+4. **M3 — Auth (§4)** *(functional pass)*: native password+TOTP login (429 handling), token storage,
+   refresh interceptor, logout, `/auth/me` role re-validation, the access-level menu. Custom-Tab
+   **hand-offs** to the website for register / invite / password-reset / SSO (no native screens for
+   those). (An optional biometric app-lock was considered here, then descoped from v1 at M6.)
+   *Prerequisite:* the website password-reset flow (§8) is already built.
+5. **M4 — Player self-service & game data** *(functional pass)*: account management (via
+   `/auth/me/*`), game-account linking, own roster/characters/vendors/houses/sales — **text-only**
+   presentation (§6.3).
+6. **M5 — Design pass & final UI (§2.1)**: with the functional Kotlin from M1–M4 working end-to-end,
+   **Claude Design produces the front-end design** for the app, then **Claude Code implements the final
+   UI to it** — Compose screens, Material 3 theming from the per-shard branding (§3), reusable
+   components, loading/error/empty states, the designed access-level menu. Restyles the existing
+   screens only; no changes to architecture, data flow, or endpoint contracts. Text-only game data
+   (§6.3) still holds — this is visual design of the data screens, not paperdoll art. **Landed**
+   2026-07-20 (`RunicGateway/Android-app#10`): dark-only shard-website theme, Cinzel display face,
+   reusable pill/label/card/meter components; brand-accent seeding retained (see §9 build progress).
+7. **M6 — Polish & release mechanics**: settings (server switch = hard reset, done M3),
+   version-mismatch guard, release build hardening (HTTPS-only, no token logging, R8 minify + resource
+   shrink, release signing). No offline cache in v1 (§7). **Ships v1 as a signed APK attached to a Gitea
+   release** via `release.yml` on a `v*` tag (see §10). Biometric app-lock **descoped** (below).
+   **Landed** 2026-07-20 (`RunicGateway/Android-app#11`).
+8. **M7 — Push notifications** (post-v1): add the self-hosted `ntfy` service to
+   `website/docker-compose.yml` (declarative, zero-interaction config), UnifiedPush integration in the
+   app, device registration, the subscriptions UI, and the content-free-tickle backend fan-out (see
+   §11). The app is built with room for this from M0 but it does not gate the first release.
+   ✅ **Both parts landed** 2026-07-20 — Part 1 backend (`RunicGateway/website#78` merged + docs#20),
+   Part 2 app (`RunicGateway/Android-app#15`) + a small `push.ntfyUrl` settings addition
+   (`RunicGateway/website#79`). The app embeds its own ntfy distributor (a foreground-service SSE
+   connection, no second app, no Google Play Services, no UnifiedPush library); see the "M7 plan"
+   Part 2 block for the recorded transport + backend-field decisions. Push delivers once the shard sets
+   its `NTFY_*` deploy config (§13).
+9. **M8 — Google Play**: Play Console listing, signing/upload key, and (optionally) an FCM build flavor
+   — after the direct-APK release is stable.
+10. **M9 — Native SSO login** (post-v1, additive; independent of M8): in-app "Sign in with Google /
+    Discord" via the **Mobile SSO Authorization Bridge** (§4.2). **Backend-first**, mirroring M7's
+    split:
+    - **Part 1 — backend + docs (in progress):** `mobile_auth_sessions` + `mobile_auth_codes` bridge
+      tables; `GET /auth/mobile/sso/start` (seeds a bridge session, reuses the existing SSO redirect
+      tagged `mode:'mobile'`); a mobile branch in the SSO callback + TOTP-completion that mints a
+      single-use, hashed, PKCE-bound authorization code and redirects to the fixed app callback instead
+      of setting a cookie; `POST /auth/mobile/sso/exchange` (code + PKCE verifier → the existing mobile
+      bearer token pair); an exact-match redirect-URI allowlist; boot-time + opportunistic cleanup of
+      the bridge tables. Reuses `GET /auth/providers` for discovery and `POST /auth/mobile/{refresh,
+      logout}` unchanged. See `../website/BACKEND_DESIGN.md`.
+    - **Part 2 — app client:** register the `runicgateway://auth/callback` intent-filter; generate
+      `code_verifier`/`code_challenge` + `state`; open the Custom Tab at `/auth/mobile/sso/start`;
+      verify `state` on the callback; `POST …/exchange`; store the returned pair in the existing
+      `TokenStore` (M3). No new token-storage or refresh code — it feeds the M3 session machinery.
+    - **Follow-up — App Links (opt-in hardening on top of Part 2):** a website `GET
+      /.well-known/assetlinks.json` route behind the `mobile_app_links_enabled` admin toggle, a
+      self-origin HTTPS entry added to the redirect-URI allowlist when enabled, and an app-side
+      `autoVerify` intent-filter for `https://<host>/mobile/callback` driven by a **build-time**
+      `appLinkHost` (a single multi-tenant APK cannot autoVerify open-ended shard domains, so the
+      generic build stays custom-scheme; white-label/first-party builds bake one host). The custom
+      scheme remains the permanent fallback on every build. Full spec + rollout in
+      [`APP_LINKS.md`](./APP_LINKS.md).
+
+---
+
+## 10. Distribution
+
+- **v1: direct APK.** Build a signed release APK in CI and **attach it to a Gitea release** (mirrors
+  how `link/` cuts release binaries). Users sideload; the app already self-configures its server URL on
+  first run (§3), so one APK works for any shard. Keep a stable **upload/signing keystore** out of the
+  repo from day one — Play later requires a consistent signing identity.
+- **Later: Google Play.** Add a Play Console listing and (if using FCM) a `google-services` config as a
+  **build flavor**, so the direct-APK build stays Google-free. Versioning: semantic `versionName` +
+  monotonic `versionCode`; tag releases in the repo.
+
+## 11. Push notifications (built-for, shipped post-v1)
+
+The app is architected from M0 to accommodate push, but push itself ships in M7 — it does not block the
+first release. Users **opt in per stream**: nothing is pushed unless subscribed.
+
+### Transport — UnifiedPush via self-hosted ntfy (decided)
+- **Primary: UnifiedPush, delivered by a self-hosted `ntfy` service added to the website's
+  `docker-compose.yml`.** FOSS, no Google Play Services dependency, works for the sideloaded APK on any
+  device, and keeps delivery under the org's own infrastructure — consistent with the self-hosted ethos.
+- **The app embeds its own distributor — no second app (decided; see M7 Part 2 work item 1).** ntfy is
+  purely the relay *server*; the Runic Gateway app receives notifications itself via an in-app embedded
+  UnifiedPush distributor (a foreground-service persistent connection to the shard's ntfy). The user
+  installs one APK — never a separate distributor app — and no Google Play Services is involved.
+- **FCM stays optional and Play-only.** If/when a Play build wants it, add FCM as a **build flavor**;
+  the direct-APK flavor stays Google-free. The backend fan-out is **transport-agnostic** and dispatches
+  to whatever endpoint a device registered, so adding FCM later touches no core logic.
+
+### ntfy deployment — fully automated, zero interactive setup (hard requirement)
+- Runs as an **additional service in `website/docker-compose.yml`** (the compose *pulls* images and
+  never builds — ntfy is a pinned upstream image, so this fits that model). Confirm the exact image
+  path/tag at implementation.
+- **All config is declarative** — a committed `ntfy` config file and/or `NTFY_*` env vars baked into
+  compose. No `docker exec`, no interactive `ntfy user add`, no post-deploy manual steps. Bringing the
+  stack up provisions a working push relay. Reachable to devices via the existing reverse proxy on its
+  own hostname/path; internal-only for the backend publisher.
+- **No per-user ntfy accounts to administer.** The security model (below) removes the need for ntfy ACL
+  provisioning, which is exactly what keeps setup interaction-free. ntfy topics are the random,
+  unguessable endpoints UnifiedPush hands out; the backend treats ntfy as an **untrusted relay**.
+
+### Backend (additive, v1)
+- `POST /auth/me/devices` — register a device: `{ transport, endpoint, platform }` where `endpoint` is
+  the UnifiedPush/ntfy URL the distributor gave the app (or an FCM token for a Play/FCM build). `DELETE
+  /auth/me/devices/:id` — unregister. Devices belong to the authenticated user.
+- `GET /notifications/streams` — catalog of subscribable streams + which require a linked game account.
+- `GET|PUT /auth/me/notifications/subscriptions` — the user's selected streams (per-user; applied to
+  all their devices).
+- **Fan-out worker** hangs off the existing event dispatcher (`website` `utils/shardIngest.js`) — the
+  same event source that already feeds the SSE channels — matches events against subscriptions and
+  **publishes a content-free tickle** (see below) to each matching device's endpoint. Store endpoints
+  per device. Any secret (an ntfy publish token, or an FCM server key if that flavor is used) is
+  encrypted at rest via `utils/secretBox.js`, like the other secrets.
+
+### Stream catalog (initial)
+- **Public / opt-in** (no account needed): news posts, server up/down, IDOC warnings, champion-spawn
+  starts, governor elections.
+- **Personal** (require a linked game account; delivered only to the owner): *your* vendor sold an
+  item, *your* house entered IDOC, a login to *your* account.
+
+### Security boundary (hard requirement)
+The ntfy relay is treated as **untrusted infrastructure**, and the design makes that safe:
+
+- **Content-free tickles.** A push payload carries **no sensitive data** — only a stream id and an
+  opaque reference (e.g. `{ stream: "vendor.sale", ref: "…" }`). On receipt the app wakes and **pulls
+  the actual content over the authenticated, ownership-checked API** (`/auth/me/*`, `/player/shard/*`).
+  So even if an ntfy topic name leaked, nothing meaningful leaks with it, and no data reaches a device
+  that its user isn't already entitled to fetch. This is what lets ntfy be automated with no per-user
+  ACLs while still honoring the security rules.
+- **Same allowlist split as the SSE streams.** Sensitive kinds (staff audit, cheat detection, login
+  attempts, IPs) are never fanned out to push at all — the publisher applies the identical public/safe
+  allowlist used by the SSE dispatcher.
+- **Personal events are owner-keyed.** A personal tickle (your vendor sold, your house IDOC) is
+  published **only** to the endpoints of the owning user, decided by the same ownership check as the
+  `/player/shard/*` reads — a device never receives another user's events.
+- **Transport hardening.** ntfy served over TLS via the reverse proxy; the backend→ntfy publish is
+  internal. Endpoints are unguessable random topics; unregister on logout / token revocation.
+
+### App
+- A **Notifications** settings screen lists the catalog with per-stream toggles; personal streams are
+  disabled/greyed until the user has a linked game account. Registration happens after login; toggles
+  write to `/auth/me/notifications/subscriptions`. Tapping a notification deep-links to the relevant
+  screen (§ open item below).
+
+## 12. Build & CI (Gitea Actions)
+
+Builds run on the org's existing self-hosted runners (`runs-on: ubuntu-latest`, same label the other
+repos use), on a bare `ubuntu:latest` container.
+
+- **Toolchain:** JDK **17** (temurin) for Android Gradle Plugin 8.x; Android SDK installed in-CI via
+  `android-actions/setup-android@v3` (cmdline-tools + license acceptance). Cache `~/.gradle` and the SDK.
+- **Bare-image gotcha:** `ubuntu:latest` lacks `git`/`curl`/`unzip` that `actions/checkout` and
+  `sdkmanager` need — first step `apt-get install -y git curl unzip`. (Faster option once builds are
+  frequent: run the job under a prebuilt Android-SDK `container:` image so nothing installs per-run.)
+- **PR gate** (`.gitea/workflows/pr-checks.yml`, on PR → `main`): `./gradlew lint test assembleDebug`.
+  Debug builds are auto-signed, so the gate needs no secrets. Mirrors `website/`'s pre-merge gate.
+- **Release** (`.gitea/workflows/release.yml`, M6+): build a **signed release APK** and attach it to a
+  Gitea release (mirrors `link/`'s release job). The **keystore is a base64 Gitea Actions secret**
+  decoded in CI; store/key passwords are secrets. The keystore never lives in the repo. Keep the
+  signing identity stable from the first release (Play later requires consistency).
+- Semantic `versionName` + monotonic `versionCode`; tag releases.
+
+## 13. Open questions (revisit as we go)
+
+**Decided (recorded here for context):** single shard per install (§3); native auth is
+password+TOTP only, with registration/invite/reset/SSO **handled by the website** (§4); **password
+reset built on backend + web first**, before app work (§8); minSdk 29, compile/target 35 (§2); no
+telemetry in v1 (§2); strings externalized from day one, English-only bundled (§2); **text-only** game
+data in v1, pretty paperdoll is future (§6.3); **no offline cache in v1** (§7); push via self-hosted
+ntfy / UnifiedPush (§11) with the **distributor embedded in the app — no second app to install**
+(M7 Part 2 work item 1); **biometric app-lock descoped from v1** (tokens already encrypted at rest, so
+it is a UX convenience, not a v1 requirement — deferred at M3, descoped at M6; revisit only if requested).
+
+**Still open:**
+- **App identity / domain.** Target application ID **`com.runicgateway.app`** — pending securing the
+  `runicgateway.app` domain (needed for a verified app-link host and a matching package namespace). Also
+  the fixed launcher name (baked at build even though in-app branding is per-shard — one APK, any shard).
+  Since SSO/invite/reset are website-handled, the app mostly *opens* website URLs rather than needing its
+  own verified app links. **App Links resolved (M9 follow-up):** the SSO callback is the one place a
+  verified deep-link-back helps; the server side (`assetlinks.json` + toggle) ships for any shard, but
+  the app-side `autoVerify` needs a **literal build-time host**, so it is a white-label/first-party build
+  opt-in (`-PappLinkHost=<host>`) — the generic multi-tenant build stays custom-scheme. A canonical
+  `runicgateway.app` relay host, if secured, would let the generic build autoVerify one central domain.
+  See [`APP_LINKS.md`](./APP_LINKS.md).
+- ntfy: exact upstream image + pinned tag (Part-1 landed the compose service — confirm the tag), and
+  its reverse-proxy hostname/path. The hostname must land in `NTFY_ALLOWED_ORIGINS` before M7 Part 2 is
+  end-to-end testable (the app registers an endpoint on that origin; the SSRF guard rejects others). No
+  backend publish token — **decided** (the content-free-tickle design does not require one; optional
+  `NTFY_PUBLISH_TOKEN` is honored if ever set).
+- FCM flavor: build it for the Play release or ship Play on UnifiedPush too? Decide at M8. (The M7
+  Part 2 `PushTransport` seam keeps this swap cheap.)
+- Deep-link / share targets for wiki pages and posts (share/open-in-app). *Notification-tap* deep-links
+  are **resolved** for M7 Part 2 (stream→screen map, work item 7).
+- iOS: none planned (this is the Android-only choice); revisit only if cross-platform is later
+  required (would change §2 — and push, which would then favor a cross-platform transport).

+# Android theme plan — mirroring the website frontend
+
+This is a summary of the **website frontend theme** (source of truth:
+`website/client/src/styles/theme.css`, applied at runtime by
+`website/client/src/contexts/SiteContext.jsx`) so the native Android client can
+present a visually consistent brand. Where the web uses CSS custom properties,
+the Android equivalent is a Compose `MaterialTheme` `ColorScheme` + `Typography`.
+
+## Overall character
+
+A **dark, moody, "arcane fantasy" theme** — deep blue-black backgrounds, muted
+slate-blue accent, parchment-white text, and an engraved serif display face. It
+reads like a leather-and-moonlight fantasy ledger, not a bright consumer app.
+There is **no light mode** on the web; the app should ship dark-only to match.
+
+## Color tokens
+
+The web theme is a flat set of CSS variables under `:root`. Map them to Compose
+as follows (hex is authoritative):
+
+| Web token         | Hex        | Role                                   | Compose slot (suggested)      |
+|-------------------|------------|----------------------------------------|-------------------------------|
+| `--bg`            | `#0e1318`  | App background                          | `background`                  |
+| `--bg-deep`       | `#0b0f14`  | Deepest surface / on-accent text       | `surfaceDim` / `onPrimary`    |
+| `--panel-a`       | `#192231`  | Card gradient top                       | `surface`                     |
+| `--panel-b`       | `#141a21`  | Card gradient bottom                    | `surfaceContainer`            |
+| `--panel-flat`    | `#11161d`  | Flat panels, toolbars                  | `surfaceContainerLow`         |
+| `--line`          | `#2a3544`  | Borders / dividers                     | `outline`                     |
+| `--line-soft`     | `#1d2733`  | Subtle row dividers                    | `outlineVariant`              |
+| `--accent`        | `#7f99bd`  | **Primary accent** (brand-overridable) | `primary`                     |
+| `--accent-bright` | `#cdd9e8`  | Primary button fill, active states     | `primaryContainer` / bright   |
+| `--ink`           | `#eef3f8`  | Highest-contrast text                  | `onBackground`                |
+| `--head`          | `#e6edf6`  | Headings                               | heading color                 |
+| `--text`          | `#c4cdd8`  | Body prose                             | `onSurface`                   |
+| `--muted`         | `#aeb8c4`  | Secondary text                         | `onSurfaceVariant`            |
+| `--dim`           | `#6f7d8e`  | Meta / captions / placeholders         | dim / disabled text           |
+| `--blue`          | `#13243c`  | Accent hover/active background         | `secondaryContainer`          |
+| `--mode-live`     | `#5fb98a`  | "Shard live" status (green)            | success                       |
+| `--mode-maint`    | `#e6c26a`  | "Maintenance" status (amber)           | warning                       |
+
+### Semantic / status colors (used in badges, diffs, moderation)
+
+- **Success / published / live:** green `#5fb98a` (fills at ~16–22% alpha, text `#7fd0a4`).
+- **Warning / maintenance / moderation (kick/mute/warn):** amber `#e0b070` / `#e6c26a`.
+- **Danger / ban / red-link / errors:** desaturated red `#d98b84` (borders `#6e3b38`).
+- **Admin badge:** near-white `#d8e2ef` on `#3a4a5e`.
+
+## Branding is data, not code
+
+The `--accent` value is **overridden at runtime** per shard instance. On the web,
+`SiteContext` reads `brand.accent` from the site settings API and sets the CSS
+variable, so one build reskins for any shard. **The Android app should do the
+same:** fetch the brand payload (name, `accent`, colors, logo/hero/favicon) from
+the website API and derive the `primary` color at runtime rather than hardcoding
+`#7f99bd`. Default to `#7f99bd` when the brand payload is absent/offline.
+
+## Typography
+
+Three font families, by role:
+
+- **Display** (`--display`): **Cinzel**, falling back to Georgia serif — an
+  engraved Roman capitals face used for the logo, `h1`/`.h1`, and prose
+  `h2`/`h3`. Bundle Cinzel as an app font; this face carries the brand.
+- **Serif body** (`--serif`): **Georgia / Times New Roman** — default body and
+  prose text; `line-height ≈ 1.6`.
+- **Sans** (`--sans`): **Helvetica Neue / Arial** — UI chrome: buttons, pills,
+  form labels, table headers, badges, meta. Labels/eyebrows/kickers are
+  UPPERCASE with wide letter-spacing (`0.1–0.18em`) and small (0.68–0.86rem).
+
+Heading scale is fluid on web (`h1` clamps ~2.4–3.6rem); pick fixed Material type
+scale equivalents (e.g. display for `h1`, headline for `h2`, title for `h3`).
+
+## Shape, elevation & motion
+
+- **Corners:** cards/panels `10–12px` radius; inputs/small elements `8px`;
+  pills and buttons are **fully rounded** (`999px` / capsule).
+- **Cards:** vertical gradient `--panel-a → --panel-b`, 1px `--line` border, soft
+  drop shadow (`0 14px 34px rgba(0,0,0,0.3)`). On hover the web lifts `-3px` and
+  brightens the border to `--accent` — translate to a pressed/focused accent
+  border on Android.
+- **Buttons:** primary = bright fill (`--accent-bright`) with dark text;
+  ghost/secondary = translucent dark fill with accent-on-hover border.
+- **Motion:** short, subtle transitions (0.12–0.18s). Keep animations understated.
+
+## Signature accents (nice-to-have)
+
+- The **"moon"** motif: a radial-gradient sphere (`#eef3f8 → #9fb0c6 → #5d6e88`) —
+  a small brand flourish worth reproducing.
+- Accent-tinted focus rings and left-border "note" callouts
+  (`border-left: 3px solid --accent` over a translucent `--blue` background).
+
+## Implementation note for Compose
+
+Define one `darkColorScheme(...)` from the table above, a `Typography` binding the
+three families, and a `Shapes` set (`small = 8.dp`, `medium = 10.dp`, capsule for
+buttons). Load `accent` from the brand API into a state holder and rebuild the
+`primary` (and derived `primaryContainer`) at runtime so a shard's custom accent
+flows through the whole UI — exactly as `SiteContext` does on the web.

+# SonarQube static analysis
+
+Each code repo in the Runic Gateway org reports static-analysis results to the
+self-hosted **SonarQube** server for review. Analysis is **non-blocking**: it
+runs on push to `main` (i.e. *after* merge), never on pull requests, so it never
+gates a PR. It complements each repo's PR gate and release pipeline — it only
+feeds the dashboard.
+
+## Server
+
+- **URL:** `https://sonar.whitlocktech.com`
+- Each repo is a separate SonarQube project, keyed as below.
+
+## Projects
+
+| Repo | Project key | Sources analysed | Language |
+|---|---|---|---|
+| `website` | `runic-gateway-website` | `server/src`, `client/src`, `bot/src` | JS/TS |
+| `link` | `Runic-Gateway-link` | `sidecar/src` | Rust |
+| `Android-app` | `Runic-Gateway-Android-app` | `app/src/main` | Kotlin |
+
+> Project keys are **case-sensitive** and must match what already exists on the
+> server — SonarQube refuses to create a key that differs only in case from an
+> existing one. `link` and `Android-app` reuse the pre-existing capitalised keys
+> above; `website` predates this note with its lower-case key.
+
+## How it's wired
+
+Each repo carries two files, identical in shape across repos:
+
+- **`sonar-project.properties`** (repo root) — declares the project key, sources,
+  tests, and exclusions. The Sonar scanner reads this.
+- **`.gitea/workflows/sonarqube.yml`** — a `SonarQube` workflow that, on push to
+  `main` (and via manual `workflow_dispatch`), checks out with full history
+  (`fetch-depth: 0`, needed for accurate blame + "new code") and runs
+  `sonarsource/sonarqube-scan-action@v4`.
+
+The scan is **source-based** — it does not build the project or run a language
+toolchain, so the workflows are lightweight (checkout + scan only). Richer
+signals (Rust Clippy, Android Lint, JaCoCo coverage) are left as documented,
+commented-out enrichment in each repo's `sonar-project.properties`; enable them
+per repo when wanted.
+
+## One-time setup per repo (Gitea UI → Repo → Settings → Actions)
+
+Both are consumed by the scan action via `env:` in the workflow:
+
+- **Secret `SONAR_TOKEN`** — a SonarQube *Analysis* token (My Account →
+  Security in SonarQube; project-scoped or global).
+- **Variable `SONAR_HOST_URL`** — the SonarQube base URL reachable from the
+  self-hosted runner. Kept as a **variable, not committed**, so the internal
+  address stays out of git.
+
+The self-hosted `ubuntu-latest` runner must be able to reach `SONAR_HOST_URL` on
+the network. Nothing waits on the SonarQube Quality Gate, so a failing gate does
+not fail the job — check the dashboard.
+
+## Adding a new repo
+
+1. Create the project in SonarQube; note its key.
+2. Add `sonar-project.properties` (copy an existing repo's, adjust key + sources).
+3. Add `.gitea/workflows/sonarqube.yml` (copy verbatim — it's language-agnostic).
+4. Set the `SONAR_TOKEN` secret and `SONAR_HOST_URL` variable in the repo's
+   Gitea Actions settings.

-No public `register`. First admin is bootstrapped by `seed.js` from env (see §6). Further
-admins are created under `/admin/users`.
+**Role-agnostic self-service (`/auth/me/*`).** The canonical "me" surface for **every** authenticated
+role. It reuses the exact `account.controller` handlers as `/player/account/*` and `/admin/account/*`
+(no logic duplication) behind `requireAuth` **only** — any active account, never a specific role. This
+lets a client (the Android app) manage its own account through one surface without ever touching
+`/admin` (docs/android/PLAN.md §6.4). The older `/player/account/*` + `/admin/account/*` routes stay
+for web back-compat.
+
+**Password reset.** Uses the same audited pattern as `user_invites`: an opaque 32-byte token
+whose **sha256 hash only** is stored in `password_resets`, single-use and short-lived (~1h). It
+also serves SSO-only accounts (null `password_hash`) as their "set an initial password" path. The
+reset link points at the web front end (`/account/reset/:token`); the Android app hands off here
+rather than shipping its own reset screen (docs/android/PLAN.md §4.2). First admin is bootstrapped
+by `seed.js` from env (see §6); further staff are created under `/admin/users` or via email invites.
+
+**Push notifications (M7, opt-in).** The app subscribes per stream (`/auth/me/notifications/*`) and
+registers device endpoints (`/auth/me/devices`); nothing is pushed unless subscribed. Delivery is a
+**content-free tickle** — `{ stream, ref }`, no sensitive data — POSTed to each subscribed device's
+self-hosted **ntfy** endpoint (`utils/pushDispatch`); the app wakes and pulls the real, ownership-
+checked content over the authenticated API. Two producers fan out through the one publisher: the shard
+ingest dispatcher (`utils/shardIngest`, beside the SSE broadcast) for shard-derived streams, and the
+create/publish-post path for `news.post`. The stream catalog + event→stream mapping is
+`config/notificationStreams.js`. Security invariants:
+- **Same public/admin split as the SSE feed.** Public streams are drawn *only* from the SSE
+  `PUBLIC_KINDS` allowlist; a sensitive kind (audit/cheat/IP/login-attempt) can never produce a public
+  push.
+- **Personal streams are owner-keyed.** `vendor.sale` / `house.idoc` / `account.login` are delivered
+  only to the *owning* user's devices, resolved via `shardLinks` (the same ownership check as
+  `/player/shard/*`).
+- **SSRF guard.** A device `endpoint` is a client-supplied URL the server POSTs to, so registration and
+  every publish validate it is HTTPS, non-private/loopback, and (when configured) on the shard's ntfy
+  allow-set (`NTFY_BASE_URL` / `NTFY_ALLOWED_ORIGINS`).
+- ntfy is treated as an **untrusted relay** — no per-user accounts, unguessable topics; an optional
+  `NTFY_PUBLISH_TOKEN` hardens backend→ntfy publishes but is not required. See docs/android/PLAN.md §11.
+
+### 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 |

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/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
+callback `runicgateway://auth/callback`) — **never prefix match** (prefix matching on custom schemes
+is a known open-redirect vector). Tokens are **never** placed in the callback URL — only the
+short-lived authorization code.
+
+*App Links (implemented).* When the admin toggle `mobile_app_links_enabled` is **on**, `/start` also
+accepts the self-origin HTTPS callback `https://<request-host>/mobile/callback` — one *additive*
+exact-match entry, derived from the request/`APP_BASE_URL` and never from client input; the
+custom-scheme allowlist is never narrowed. The shard then auto-serves `GET
+/.well-known/assetlinks.json` (fixed package `com.runicgateway.app` + `MOBILE_APP_CERT_SHA256`
+fingerprints; 404 when the toggle is off or no fingerprint is configured), and
+`settings.getPublic()` advertises `mobileAppLinks: <bool>`. These two things — one static file route
+and one more allowlist entry — are the *entire* server surface App Links require. See
+docs/android/APP_LINKS.md.
+
+**TOTP through the bridge.** A 2FA account keeps full parity: the callback stages the existing
+pending-TOTP cookie (now also carrying the bridge `session_id`) and bounces the Custom Tab through the
+web TOTP form; on a correct code the completion mints the authorization code and deep-links back to
+the app — it never mints a session cookie for a mobile flow.
+
+**Revocation latency (documented tradeoff).** Revoking a refresh token (device revoke / logout) stops
+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).

+# Runic Gateway Website — Moderation Appeals (Phase 6c/6d)
+
+> Website feature branch: **`feature/moderation-appeals`**. Builds on the moderation
+> dashboard (Phase 6a/6b) and the Discord bot's `mod_actions` log. Companion to
+> [website-README.md](website-README.md) (overview) and
+> [BACKEND_DESIGN.md](BACKEND_DESIGN.md) (base API contract).
+
+## 1. Overview
+
+A player whose linked Discord identity was **banned** or **muted** — an action
+recorded in the bot's `mod_actions` log — can open an **appeal** from the player
+portal and track its status. Staff (**admin** or **moderator** role) work the
+appeal from an **appeals queue** in the admin moderation section: claim it, then
+resolve it **approved** or **denied** with a written staff response.
+
+When staff **approve** a ban/mute appeal, the website makes a best-effort call to
+the Discord bot's internal API to actually lift the ban / clear the timeout in
+Discord, and the bot posts a mod-log embed ("Appeal approved"). This is
+**best-effort**: if the bot is unreachable the appeal still resolves as approved,
+the reversal is recorded as failed, and staff can reverse the sanction manually in
+Discord.
+
+Only **ban** and **mute** actions are appealable — the sanctions that have an
+ongoing effect. Warnings/kicks and similar one-shot actions are not.
+
+## 2. Ownership & eligibility
+
+- **`appeals` is a server-owned table** — only the website reads/writes it. It
+  references the bot-owned `mod_actions` log by a plain id column
+  (`mod_action_id`); there is **no hard cross-owner foreign key** between the two
+  databases, so the reference is validated in application code (same pattern as
+  the rest of the uo-link / bot integration, where the two services never share a
+  live FK).
+- **Eligibility** — the appellant must be a **logged-in player** whose linked
+  Discord identity (`user_identities`, `provider = 'discord'`) matches the
+  `mod_actions` row's target. A player cannot open an appeal for someone else's
+  action, and an unlinked player has nothing eligible to appeal.
+- **One active appeal per action** — only one `pending` / `under_review` appeal is
+  allowed for a given `mod_action_id` at a time; a second attempt while one is
+  already open is rejected.
+
+## 3. Appeal lifecycle
+
+```
+pending ──▶ under_review ──▶ approved
+                          └─▶ denied
+
+pending ──▶ withdrawn
+under_review ──▶ withdrawn
+```
+
+- **`pending`** — submitted by the player, not yet claimed.
+- **`under_review`** — claimed by a staffer (the claiming admin/moderator is
+  stamped on the row).
+- **`approved`** / **`denied`** — resolved by staff with an optional
+  `staff_response`. Approving a ban/mute appeal triggers the Phase 6d reversal
+  (§5).
+- **`withdrawn`** — the player pulled the appeal back before it was resolved.
+
+`reversal_status` (only meaningful on an approved ban/mute appeal) is one of
+`none` (not attempted / not applicable), `done`, or `failed`. No new
+`mod_actions` row is written for a reversal — it modifies the *original* action's
+standing rather than logging a new one.
+
+## 4. API — player (role: `player`)
+
+Base `/api/v1/player/appeals`.
+
+| Method | Path | Purpose |
+|---|---|---|
+| GET | `/player/appeals` | The caller's own appeals. |
+| GET | `/player/appeals/eligible` | The caller's ban/mute actions with no active appeal (empty if they have no linked Discord identity). |
+| POST | `/player/appeals` | Open an appeal — `{ mod_action_id, submitted_text }`. `403` if the action isn't the caller's, `400` if the action isn't a ban/mute, `409` if one is already open for it. |
+| POST | `/player/appeals/:id/withdraw` | Withdraw an appeal that hasn't been resolved yet. |
+
+## 5. API — staff (role: `admin` or `moderator`)
+
+Base `/api/v1/admin/moderation/appeals`, alongside the existing moderation
+section.
+
+| Method | Path | Purpose |
+|---|---|---|
+| GET | `/admin/moderation/appeals?status=&limit=&offset=` | The queue. Defaults to `pending` + `under_review`; pass `status=all` or a specific status to filter. |
+| GET | `/admin/moderation/appeals/:id` | One appeal. |
+| POST | `/admin/moderation/appeals/:id/claim` | `pending` → `under_review`, stamping the claiming staffer. |
+| POST | `/admin/moderation/appeals/:id/resolve` | `{ status: 'approved' \| 'denied', staff_response? }`. On an approved ban/mute, triggers the Discord reversal (§6). |
+| GET | `/admin/moderation/user/:discordId/appeals` | A user's appeals — shown as a tab on the per-user moderation history page. |
+
+`resolve` returns a `reversal` object describing what happened:
+
+```jsonc
+{
+  "reversal": {
+    "attempted": true,
+    "ok": true,
+    "reversal_status": "done",   // "none" | "done" | "failed"
+    "bot_status": 200,
+    "error": null
+  }
+}
+```
+
+## 6. Auto-reversal (Phase 6d)
+
+On `resolve` with `status: 'approved'` against a ban/mute appeal, the website
+calls the Discord bot's internal API:
+
+```
+POST /internal/mod-reverse
+```
+
+— gated by the same shared-secret scheme as the existing `/internal/announce`
+call. The bot lifts the ban / clears the timeout for the target and posts an
+"Appeal approved" embed to its mod log.
+
+The call is **best-effort**: the appeal resolution itself always completes
+(the appeal is marked `approved` and the staff response is saved) regardless of
+whether the bot answers. If the bot is down or the call otherwise fails,
+`reversal_status` is recorded as `failed` and staff are expected to reverse the
+sanction by hand in Discord; the `reversal` object in the `resolve` response
+surfaces `ok: false` and an `error` so the UI can flag it. Denied appeals never
+attempt a reversal.
+
+---
+
+See [website-README.md](website-README.md) for the moderation dashboard's place
+in the wider site, and [BACKEND_DESIGN.md](BACKEND_DESIGN.md) for the base API
+conventions (auth, error shapes, response codes) these endpoints follow.
