Protocol 3.0 Part A. Replaces the static PUBLIC_KINDS allowlist - which
was the entire public/admin boundary - with per-feature, per-field
audience control an admin owns from Admin -> Shard Visibility.
Closes a live leak. BridgeJson.Actor() writes acct and webId;
shapeGuild() returned the stored payload verbatim; GET
/api/v1/public/shard/guilds is anonymous. Guild leaders' game account
names and website user ids were readable by anyone, and the same path
existed for governors. Both are now projected.
The ladder is anonymous < logged_in < player < staff < admin, each rung
implying the ones below. Staff satisfy `player` without a linked account
(as /player/* already does); `editor` is a content role and gets no
shard privilege, since mapping it to staff would silently widen what
editors see.
Two invariants are code, not configuration, and both reject rather than
silently ignore:
1. acct/webId are admin-only always - not configurable, discarded on
read as well as rejected on write.
2. A kind absent from KIND_FEATURE never reaches anyone below admin.
Fail closed, so a shard emitting a new event degrades to staff-only
rather than to public.
Enforcement is three points over one config: requireFeature() on routes
(404 disabled, 403 out-of-rung) plus field projection; per-connection
filtering on SSE, where a subscriber's rung is resolved once at subscribe
time and frozen so a long-open stream cannot gain privilege; and
/public/shard/features so the SPA hides links it cannot follow.
PUBLIC_KINDS still exists and is still exported (/feed filtering,
notificationStreams) but is now derived from the kind map, so the two
can no longer drift. Defaults reproduce pre-3.0 behavior exactly - a
test pins the derived set against the old allowlist.
Also fixes an SSE resource leak found while testing: a client dropped
because its write threw was removed from the bucket but its keepalive
interval was never cleared, firing forever on a dead socket. Both paths
now go through one drop().
Tests: 478 server (33 new across shardVisibility + shardBroadcast),
43 client. Route manifest and OpenAPI spec regenerated.

Prepares the committed spec for the admin router domain split
(docs/website/API_V2_PLAN.md § Phase 2) by post-processing swagger-autogen's
output in swagger/swagger.js. No route, handler or annotation changes.
Trailing slashes are stripped from path keys. swagger-autogen builds a path by
string-concatenating the mount prefix with the route argument, so a capability
router mounted at /users whose collection route is router.get('/') documents as
/api/v1/admin/users/ — advertising a URL no client calls while dropping the one
the SPA, the Android app and the Discord bot all do. Express is indifferent
(non-strict routing treats the two as one route, and routes.manifest.json records
the canonical slash-less form), but the published spec is a contract. The split
creates one of these per capability router, so it is fixed once here rather than
by contorting the route declarations in every router file.
Path keys are also sorted. The generator emits them in router-traversal order, so
moving a route between files rewrites most of this ~5k-line committed artifact
even when the API is provably unchanged, burying the one line a reviewer needs to
see. OpenAPI attaches no meaning to path order, and scripts/routeManifest.js
already sorts for the same reason.
Verified inert: the regenerated spec is byte-for-byte the sorted form of the
previously committed one — same 198 operations, zero added or removed, and no
trailing-slash keys (there were none to strip yet; the guard is for the split).
A collision after normalization throws rather than silently dropping an
operation. Server tests green (434/434).

Add opt-in "Trust this device" so a browser/app skips the TOTP step (never
the password) for 30 days, single-use bcrypt recovery codes as a 2FA-lockout
fallback, and admin trusted-device/MFA-reset management — backend, web UI,
OpenAPI spec, and tests.
- Schema: trusted_devices (sha256 token hash, looked up by unique index) and
recovery_codes (bcrypt, single-use). Both additive/idempotent.
- Session service: trust-token mint/hash/resolve + cap helpers; new rg_trust
httpOnly cookie (survives logout, revoked on untrust/password change/reset/
TOTP disable). JWTs stay stateless — trust is a server-side row, not a claim.
- Web + mobile login accept a trusted-device token / recovery code; login/totp
gains trustDevice + recoveryCode. Cap of 10/user with NO silent pruning — an
over-cap trust returns 409/trustLimitReached and the client prompts to revoke.
- Self-service /auth/me/trusted-devices* + recovery-codes*; admin
/admin/users/:id/trusted-devices* + /mfa/reset. All actions audit-logged.
- Client: "Trust this device" + recovery-code login options, one-time recovery
code display, Trusted Devices + Recovery Codes account panels, a TOTP-styled
revoke-to-continue cap modal, and admin per-user security controls.
- OpenAPI regenerated; 33 new server tests (all suites green).

Adds the self-service device-session surface the mobile-SSO spec requires, on
top of the existing mobile_refresh_tokens store.
- Schema: device_name + last_used_at columns on mobile_refresh_tokens (nullable,
additive via the ALTER section; seeded to now on insert). With single-use
rotation each login/refresh inserts a fresh row, so the active row's timestamp
is the session's last activity, and the label is carried forward on refresh.
- Model: listActiveForUser (one row per live device, no token hash) +
revokeByIdForUser (ownership-scoped, idempotent).
- GET /auth/me/sessions + DELETE /auth/me/sessions/:id (role-agnostic, behind
requireAuth). Named distinctly from /auth/me/devices (push endpoints).
- device_name is an optional field on /auth/mobile/login and
/auth/mobile/sso/exchange so the app can label a device.
- Client: an "Active Devices" panel on the player account page (list + sign a
device out), plus the PlayerLogin change to honor the mobile SSO bridge's
{ redirect } deep link on a 2FA completion.
- Swagger DeviceSession schema + regenerated spec; 3 controller tests. Full
server suite green (274); client builds.

Add a Mobile SSO Authorization Bridge so the native app can "Sign in with
Google/Discord" without shipping any OAuth secret. It EXTENDS the existing
/auth/sso/* redirect flow (same PKCE-vs-IdP, link-only + opt-in provisioning,
TOTP gate) and terminates in the existing mobile bearer tokens — not a parallel
auth path.
- Schema: mobile_auth_sessions + mobile_auth_codes (short-lived, self-pruning;
authorization code stored hash-only, PKCE challenge is a hash by construction).
- GET /auth/mobile/sso/start: validate provider enabled + redirect_uri by EXACT
allowlist match (never prefix), seed a bridge session, reuse the SSO redirect
tagged mode:'mobile' (new redirectToIdp helper extracted from beginFlow).
- SSO callback + finishSsoTotp gain a mode:'mobile' branch: mint a single-use,
hashed, PKCE-bound code and redirect to the fixed app callback (code + echoed
state, never a token) instead of setting a cookie. 2FA keeps full parity via
the existing web TOTP form (now carrying the bridge session).
- POST /auth/mobile/sso/exchange: verify Layer-B PKCE (before burning the code),
single-use consume, then issue the SAME pair as /auth/mobile/login.
- Discovery reuses GET /auth/providers; refresh/logout reuse /auth/mobile/*.
- Rate limits: /start per-IP+provider, /exchange per-IP. Boot-time +
opportunistic prune of both tables (no cron, mirrors revoked_sessions).
- Redirect allowlist is MOBILE_AUTH_REDIRECT_URIS (default the one fixed
runicgateway://auth/callback); App Link URIs can be appended per shard later.
- Swagger regenerated; 39 tests (model single-use/gating + full controller
matrix: bad/expired/reused code, PKCE mismatch, disabled provider, redirect
allowlist, TOTP-through-bridge). Full suite green (271).

The Android app's embedded push distributor (M7 Part 2) needs the shard's
client-facing ntfy relay URL to build its device topic endpoint, but the M7
Part 1 backend only used the NTFY_* vars server-side and never surfaced them.
Add a `push: { ntfyUrl }` block to settings.getPublic(), sourced from
NTFY_PUBLIC_URL or the first NTFY_ALLOWED_ORIGINS entry (never the possibly
internal NTFY_BASE_URL); null when unconfigured, so the app shows push as
unavailable for that shard. Additive, non-sensitive, forward-compatible.
- Extend the PublicSettings swagger schema; regenerate swagger-output.json.
- publicBrand.test.js: cover null / NTFY_PUBLIC_URL / NTFY_ALLOWED_ORIGINS.
- Document NTFY_PUBLIC_URL in .env.example and (docs PR) BACKEND_DESIGN.md.
Full server suite green (250 pass).

Additive, v1-only backend contract for the Android app's opt-in push (Part 1 of
M7; docs/android/PLAN.md §11). The app is a pure consumer — this lands the
endpoints, fan-out, and relay it needs.
- Schema: push_devices (per-device endpoint) + notification_subscriptions
(per-user opted-in streams), FK→users ON DELETE CASCADE.
- Stream catalog + event→stream mapping (config/notificationStreams.js): public
streams (news.post, server.status, idoc.warning, champ.start, governor.election)
drawn ONLY from the SSE PUBLIC_KINDS allowlist; personal owner-keyed streams
(vendor.sale, house.idoc, account.login). Full-state upserts (champ/city) fire
only on a real transition via an injectable tracker.
- Fan-out (utils/pushDispatch.js): content-free tickles ({ stream, ref }) POSTed
to each subscribed device; never throws. Two producers — shardIngest.ingest
(beside the SSE broadcast) and the create/publish-post path (news.post).
Personal events resolve to the owner via shardLinks. SSRF guard: endpoints must
be HTTPS, non-private, and on the NTFY_BASE_URL/NTFY_ALLOWED_ORIGINS allow-set —
enforced at registration and every publish.
- Routes under the role-agnostic self surface (never /admin): POST|GET
/auth/me/devices, DELETE /auth/me/devices/:id, GET
/auth/me/notifications/streams, GET|PUT /auth/me/notifications/subscriptions.
Swagger regenerated (4 paths, PushDevice/NotificationStreams/etc. schemas).
- ntfy service in docker-compose.yml: pinned image, declarative ./ntfy/server.yml,
no published host port, anonymous unguessable topics (no accounts) — zero
interactive setup. No publish token required (content-free design); optional
NTFY_PUBLISH_TOKEN honored.
- Tests: pushDispatch (mapping, PUBLIC_KINDS gate, owner-keying, SSRF guard,
content-free payload) + notifications route auth gate. Full suite green (247).

Branding is already returned by GET /public/settings (the `brand` block:
name/colors/logo/hero/favicon, per-shard from BRAND_*). §8.6 of the Android
plan asks to confirm it — this makes it a first-class part of the contract so
the app's OpenAPI codegen produces typed branding instead of an untyped map.
- Swagger: add Brand + PublicSettings schemas; /public/settings now references
PublicSettings (was additionalProperties:true). Brand documents that asset
fields may be site-relative paths (resolve against the base URL).
- test/publicBrand.test.js locks the brand theming contract the app depends on
(all fields present; BRAND_* defaults; admin site_title/contact_email
overrides; accentInt never leaked).
No behavior change to the response — it already carried `brand`; this types and
guards it.

Expose a small backend identity/version descriptor (§8.4 of the Android plan)
so a client can positively recognize a Runic Gateway backend on first-run and
run a version-mismatch guard, instead of inferring from an incidental shape.
- New config/version.js: { service: 'runic-gateway', api: 'v1', server: <pkg> }.
- GET /public/status now includes a `version` block (the app already calls this
on first-run, so it gets identity + version in one round trip).
- New GET /public/version: a lightweight, DB-free identity endpoint — the
canonical target for the version guard and a cheap liveness check.
- Swagger: PublicVersion schema + version on PublicStatus; /version annotated.
- test/publicVersion.test.js covers the config shape and the DB-free 200.

Players whose linked Discord identity was banned or muted can now submit
an appeal from the portal and track it; staff get a queue in the admin
moderation section to claim and resolve (approve/deny) appeals. Approving
a ban/mute appeal best-effort asks the Discord bot to reverse the action
(unban / clear timeout) via the internal API and posts a mod-log embed; a
down bot never fails the resolution (reversal_status is recorded).
- Schema: new server-owned `appeals` table (no cross-owner FK to
mod_actions; existence validated in app code).
- Server: model/appeals/* + player appeals controller (submit/mine/
eligible/withdraw) and admin queue handlers (list/claim/resolve/
per-user) under the existing admin+moderator gate; one-active-appeal
enforced app-side; eligibility keyed on the caller's linked Discord id.
- 6d: bot POST /internal/mod-reverse (+ modLog.postReversal) and
server botInternalClient.reverseModAction, wired into resolve().
- Client: admin Appeals queue + resolve modal, ModerationUser appeals
tab, player Appeals page (submit/withdraw), nav + routes + api methods.
- Docs: swagger annotations + component schemas, regenerated output.
- Tests: appeals controller + pure suites (server npm test 224 green).

Replace baked-in UOM/MysticMoon/UOMysticmoon branding with a BRAND_* env
scheme so one prebuilt image runs as any shard; UOMysticmoon becomes the
first tenant that sets these vars rather than a special case in the code.
Architecture (chosen because the app ships as a prebuilt image):
- server/src/config/brand.js + bot/src/brand.js read BRAND_* once at boot,
with Runic Gateway defaults.
- Text/colors reach the SPA at RUNTIME through the existing public settings
API (settings.model.getPublic -> SiteContext), so no client rebuild. The
admin-editable site title + contact email still override BRAND_NAME/email.
- SiteContext applies BRAND_ACCENT_COLOR to the --accent CSS var at runtime.
- Express templates the built index.html <title>/description/OG/favicon at
serve time from BRAND_* (renderIndexHtml in app.js).
- Server-side consumers read brand directly: emails, TOTP issuer, API docs,
boot logs, HTML error page. Bot uses it for embed color + logs.
Assets: logo/hero/favicon delivered from a ./brand:/app/brand bind-mount
(BRAND_LOGO/HERO/FAVICON), with neutral defaults baked in; hero falls back
to a built-in image when unset.
Scope: also genericized package.json names (uomysticmoon-* -> runic-gateway-*)
and the DB_NAME/DB_USER/COOKIE_NAME code defaults (runic_gateway/runic/
rg_token). Production keeps its real values by pinning them in .env — see
.env.uomysticmoon.example, which reproduces the exact UOMysticmoon identity
(proof the substitution works). Changing a deployed COOKIE_NAME invalidates
existing sessions, so UOMysticmoon pins uomm_token.
Verified: 193 server tests pass, client builds, app.js loads + templates the
built index.html, brand transform injects title/description/OG/favicon.
Public "Online now" now lists only players whose game account is linked
to a STAFF website user (admin/editor/moderator) — linked players are no
longer exposed publicly with their name and location. listOnlineLinked
joins through to users and filters on role; the section is relabeled
"Staff online".
Character/roster/vendor reads gain an admin bypass: admins may view any
character's data, while players (and editor/moderator staff) stay limited
to accounts they have personally linked. The bypass lives in the shared
player controller and only ever widens access for genuine admins.
Also finalizes the uo-link character/vendor front end (player + admin
character sheets, VendorSales component, ShardChar removed) and
regenerates swagger-output.json.

Turns the raw shard endpoints into proper, navigable pages in the site's visual
language.
- components/CharacterSheet.jsx: reusable sheet — attribute tiles, vitals bars,
resistances, skills (with bars), and equipment — styled with the shared
panel/grid vocabulary.
- Player portal with a nav bar: PlayerPortalLayout (Characters / Account tabs +
sign-out) wraps /player and /account. /player (PlayerCharacters) tells the
logged-in player if they haven't linked a game account (with the [link code
prompt) or, once linked, shows their characters grouped by account; each
character opens its sheet at /player/char/:serial. Account security moved into
the same shell (the buried "Game accounts" block was removed from it).
Login/register now land on /player.
- Public: GET /public/shard/online (redacted name+serial+map) drives an
"Online now" list on /site/shard that links to public character sheets at
/site/shard/char/:serial (ShardChar). Swagger: ShardOnlinePlayer + regenerated.
- api.shard.online added.
Verified live against the running shard: Darrow's full sheet (STR 120, 58
skills, 3 equipment) renders through the browser-facing proxy; the online list
returns the live roster; player routes 401 without a session.

activity.log it; bad/expired codes → 400, shard down → 503.
- GET /player/shard/accounts — the caller's linked accounts.
- GET /player/shard/roster/:account and /vendors/:account — live round-trips,
ownership-checked against the mirror (403 otherwise), 503 on shard restart.
- player.routes.js: mounted under the existing requireRole('player') gate with

Curated, same-origin, token-free reads so the browser never sees the sidecar
URL or token:
- public/shard.controller.js:
- GET /public/shard/status — connection state + online count + latest economy
(from the site's ingested data).
- GET /public/shard/feed?kind=&limit= — recent notable events from the log.
- GET /public/shard/economy — gold-supply series (oldest → newest).
- GET /public/shard/idoc — houses currently at IDOC.
- GET /public/shard/char/:serial — live sheet round-trip via uoLinkClient,
briefly cached; 503 (shard restarting) serves a stale cache or a retry
banner rather than an error.
- GET /public/shard/stream — public SSE channel (safe kinds only).

The route-level annotations were 100% present, but the committed/served
spec (swagger-output.json) was stale and several response schemas had
drifted from the controllers. This aligns the docs with actual behavior
and regenerates the spec.
Served spec was stale (64/67 operations). Regenerating picks up three
routes that were added after the last generation:
- POST /api/v1/auth/sso/totp
- GET /api/v1/admin/discord-bot/config
- PUT /api/v1/admin/discord-bot/config
plus a stale /auth/logout summary.
Response-shape corrections (annotation now matches controller output):
- Mutation endpoints do NOT return the generic { message } envelope.
Deletes echo { id } / { slug }; toggles return { deleted },
{ unlinked }, { totp_enabled }, or { ip, removed }. Documented as-is
via new DeletedId/DeletedSlug/DeletedFlag/UnlinkedFlag/TotpState/
UnbanResult components. (The API is intentionally inconsistent here;
recorded rather than normalized — see follow-up note.)
- POST /account/totp/setup: otpauth_url -> otpauthUrl (TotpSetup)
- PUT /admin/site-mode: { mode } -> { site_mode, changed_at, changed_by }
- GET /account: full User -> AccountStatus (id/username/role/totp_enabled)
- GET /account/identities: add linked_at (LinkedIdentity)
- GET /public/status: add status_message (PublicStatus)
- POST /auth/sso/totp: user is SafeUser, not full User
- GET /dashboard: description/shape corrected (posts+users, no wiki)
Schema completeness:
- Provider (public discovery): { id, name, icon, loginUrl, priority },
not { id, name, kind }
- ProviderConfig: add hasSecret, builtin, health (ProviderHealth)
- Post: add excerpt, author_id, published_at
- MobileTokenResponse.expiresIn: duration string ("15m"), not integer
Config: declare the Admin · Discord Bot tag (was used but undeclared).
Auth model and the internal/external boundary were verified correct and
left unchanged: cookie + bearer are both accepted on session routes (dual
security annotations are accurate), and /internal/* runs on a separate
listener already excluded from the scan.

Generate an OpenAPI 3.0 spec from route annotations and serve it with
Swagger UI so the full REST API is browsable and testable.
- Add swagger-ui-express (runtime) and swagger-autogen (dev) deps, plus
an `npm run swagger` script.
- server/swagger/swagger.js: generator config with API metadata, servers,
14 tag groups, cookie + bearer security schemes, and 28 reusable
component schemas. Follows the Express mount chain from src/app.js so
generated paths are fully-qualified (/api/v1/...).
- Annotate every route (auth, mobile, sso, public, admin, health) with
#swagger tags/summaries/parameters/request bodies/security and the
actual response codes each handler returns (400/401/403/404/409/429/
302/502, multipart uploads).
- Serve Swagger UI at /api/docs and the raw spec at /api/docs.json,
guarded so a missing spec disables docs instead of crashing.
- Commit the generated swagger-output.json so docs work with no build
step; swagger-autogen stays dev-only and is not needed at runtime.
- README: new "API documentation (Swagger)" section plus tech-stack and
project-structure entries.
Covers 51 paths / 64 operations. Existing test suite (83) still passes.
