 ## Lessons
 
+### Scope per-user UI state by user id, not by the client database [persistence] [multi-user] [custom-emoji]
+
+- **Trigger:** custom emoji "saved library" membership was a single `savedByUser` flag on the shared emoji row plus a long-lived singleton (`CustomEmojiService`) that merged state across logins — so a second account on the same client (and the Electron shared SQLite DB) inherited the first user's picker.
+- **Rule:** when state is "per signed-in user" but the asset/row store is shared (Electron `custom_emojis`, or a renderer singleton that survives logout), key the membership by user id in its own store (`localStorage` `metoyou_custom_emoji_saved:<userId>`, mirroring the existing per-user usage ranking) and rebuild it in `loadForUser`; never rely on a global row flag or assume the singleton was reset on logout.
+- **Why:** the browser already isolates rows per-user database, so the leak only reproduces in-session (no reload) and on Electron's shared DB — both invisible if you only test reloads; a row-level flag also can't represent two local users saving the same asset.
+- **Example:** `CustomEmojiService.resolveSavedIds(userId, emojis)` reads/seeds a per-user id set; e2e `e2e/tests/chat/custom-emoji-user-binding.spec.ts` runs the whole user switch in ONE page load (client-side router nav only) so the singleton-retention leak is actually exercised, and the second user *joins* the first user's server instead of creating one (in-session "create a second server" leaves `sourceId` empty and the submit disabled).
+
+### Don't strand signed-out mobile users on a logged-out dashboard [auth] [mobile] [routing]
+
+- **Trigger:** `App.ngOnInit` special-cased mobile — signed-out visitors landing on `/` or `/dashboard` were kept on `/dashboard` (the "login form has no mobile chrome" rationale), so mobile users got a logged-out dashboard and never saw a login screen on startup.
+- **Rule:** decide startup routing for signed-out users with the platform-agnostic pure rule `resolveUnauthenticatedStartupRedirect(currentUrl)` (`auth-navigation.rules.ts`) — non-public routes → `/login` (with safe `returnUrl`), public routes (`/login`, `/register`, `/invite/...`) → stay; do not branch on `isMobile()` here.
+- **Why:** the mobile exception directly contradicted the product expectation ("greet signed-out users with the login screen"); the login form already links to register, so there is no dead-end to avoid.
+- **Example:** unit `auth-navigation.rules.spec.ts` (`resolveUnauthenticatedStartupRedirect('/dashboard') === { path:'/login', queryParams:{} }`); e2e `e2e/tests/mobile/mobile-login-on-startup.spec.ts` sets a 390×844 viewport **before** navigating (so `ViewportService.isMobile` is true at bootstrap) and asserts `/dashboard` and `/` both land on `/login`.
+
+### "Shared from your device" must gate on local bytes, not uploader user id [attachments] [multi-device]
+
+- **Trigger:** a second device of the same user showed "Shared from your device" and hid the download affordance for a file uploaded from another device — `isUploader(attachment)` returned `uploaderPeerId === currentUserId`, but `uploaderPeerId` is the **user** id (set to `currentUser.id` in `publishAttachments`), so it is true on every device of the uploader, including ones that only synced metadata.
+- **Rule:** key the sharing/ownership UI off whether *this device* holds the bytes, not who uploaded it — use `isSharingFromThisDevice(attachment, currentUserId)` (= `isUploaderUser && deviceHasLocalCopy`) from `attachment-sharing.rules.ts`; `deviceHasLocalCopy` = `available` + blob `objectUrl`, or a non-empty `savedPath`/`filePath` (synced metadata strips local paths, so it correctly reads as "no copy").
+- **Why:** same-user devices do **not** P2P with each other and sync only via `account_sync` (which strips `filePath`/`savedPath`), so the second device legitimately has no bytes; claiming ownership blocked the only path to view/download. For the regression to even be reachable in e2e, `account_sync`'s `chat-sync-batch` had to start carrying the `attachments` map (it previously dropped attachment metadata entirely) via `pushSavedRoomMessagesViaAccountSync(..., loadAttachmentMetas)`.
+- **Example:** unit `attachment-sharing.rules.spec.ts` (`isSharingFromThisDevice({uploaderPeerId:'u1', available:false}, 'u1') === false`); e2e `e2e/tests/chat/multi-device-attachment-sharing.spec.ts` uploads on device A then logs device B in afterward so the `account_sync_peer_online` full-state push delivers the attachment, then asserts device B shows a Request button and **no** "Shared from your device".
+
+### Generate Android brand icons from the source mark; guard against stock Capacitor placeholders [mobile] [android] [assets]
+
+- **Trigger:** the Android app shipped the default Ionic/Capacitor launcher icon (and a white adaptive background) because no brand icon was ever generated into `toju-app/android/app/src/main/res/`.
+- **Rule:** regenerate launcher + splash from `images/icon-new-rounded.png` with `npm run cap:assets:android` (`tools/generate-android-app-icons.mjs`, uses `sharp`), set the adaptive background to brand purple `#4A217A` (never `#FFFFFF`), and have the adaptive icon reference `@mipmap/ic_launcher_foreground` PNGs (delete the stock `drawable-v24/ic_launcher_foreground.xml` vector). `cap:sync` is not needed — these live in the native project, not `webDir`.
+- **Why:** a native launcher icon can't be asserted through a browser, so the regression proof is a hash guard: `mobile-android-launcher-icon.rules.ts` records the SHA-256 of every stock placeholder and the tests fail if any density still matches one. Pixel checks (purple ring + white-cat centre) confirm the brand mark actually rendered.
+- **Example:** `findStockCapacitorResources(hashByFile)` must return `[]`; unit `mobile-android-launcher-icon.rules.spec.ts` + e2e `e2e/tests/mobile/android-app-icon.spec.ts` (deterministic fs/pixel checks, no emulator).
+
+### Bind chat attachments to a pre-allocated message id, never by matching content [attachments] [chat] [mobile]
+
+- **Trigger:** caption-less media (videos/images sent with no text) grouped onto the message bubble above and left an empty message below on Android — `ChatMessagesComponent` dispatched `sendMessage` without an id, then a `setTimeout` re-discovered the message by `entry.content === content` (always `''` for attachment-only sends) and called `publishAttachments` on it.
+- **Rule:** pre-allocate the message id in the component (`planChatMessageSend` in `chat-message-send.rules.ts`), dispatch it via `MessagesActions.sendMessage({ id, ... })` (effect uses `id ?? uuidv4()`), and bind attachments to that exact id with `publishAttachments(id, files)` — never re-find the message by content/timing.
+- **Why:** empty content is shared by every attachment-only message, so content matching picks the newest match and races the async create-effect; on Android the create latency exceeds the old 100 ms timer, so the file binds to a stale sibling. The race is invisible on fast desktop browsers, so the deterministic regression proof is the unit test that asserts the dispatched action id equals the attachment-binding id, not an e2e timing game (see the "don't bump E2E timeouts for sync flakes" lesson).
+- **Example:** `planChatMessageSend(...).attachmentBinding.messageId === plan.action.id` enforced in `chat-message-send.rules.spec.ts`; behavioral guard in `e2e/tests/chat/attachment-only-message-grouping.spec.ts` (proves the id flows component→effect→attachment by requiring each caption-less attachment to render in its own bubble).
+
+### Attachment file persistence must be platform-agnostic, not Electron-only [attachments] [persistence] [mobile]
+
+- **Trigger:** `AttachmentStorageService` talked only to `window.electronAPI`, so `canWriteFiles()` returned `false` on Android (Capacitor) and in the browser — no bytes were ever persisted there, and after restart/logout-login the uploader hit "Your original upload could not be found on this device" / "no peer with this file".
+- **Rule:** keep the path/bucket layout in `AttachmentStorageService` but delegate raw IO to a pluggable `AttachmentFileStore` selected by `PlatformService` — Electron disk, Capacitor `Directory.Data` (lazy-loaded, inline media via `convertFileSrc`), and a per-user IndexedDB vfs for the browser with a finite `maxPersistableBytes` cap; gate transfer persistence on `canStreamToDisk()` / `canPersistSize()` so the cap degrades gracefully.
+- **Why:** the browser e2e harness can't test native disk, but the browser IndexedDB store is real persistence, so a single-client send → `page.reload()` → reopen-room test proves the whole persist/restore orchestration with no peer connected.
+- **Example:** `attachment-file-store.ts` + `{electron,browser,capacitor}-attachment-file-store.ts`; `e2e/tests/chat/local-attachment-persistence.spec.ts` waits for both byte records (vfs) **and** `attachments` records with `savedPath` (summed across all `metoyou`/`metoyou::<user>` DBs, since an empty anonymous-scope DB exists) before reloading.
+
+### Never count duplicate chunks toward transfer progress, and never finalize on byte counters [attachments] [webrtc]
+
+- **Trigger:** P2P attachments arrived corrupt everywhere ("only the first bytes") because concurrent auto-download triggers double-requested a file, the sender streamed it twice, and the receiver counted duplicate chunk deliveries toward `receivedBytes` — inflating it past `size`, which both dropped the remaining chunks (post-Security guard) and passed the `receivedBytes >= size` finalize shortcut over a sparse buffer.
+- **Rule:** in chunked transfer receivers, ignore an already-buffered chunk index entirely (no progress update), use dense buffers, and finalize only when every chunk index is present — never use byte totals as an alternative completion signal; dedupe streams on the sender per `(messageId, fileId, peerId)`.
+- **Why:** byte counters lie as soon as any duplicate, retry, or concurrent stream exists, and sparse-array `every`/`some` skip holes, so "looks complete" checks silently pass on partial data (same trap as the custom-emoji sparse-array lesson).
+- **Example:** `handleFileChunk` / `finalizeTransferIfComplete` in `attachment-transfer.service.ts`; multi-chunk e2e coverage via `expectMessageImageContentSha256` in `e2e/tests/chat/chat-message-features.spec.ts` (single-chunk files cannot catch assembly bugs — test with >64 KiB payloads).
+
+### Don't bump E2E timeouts for sync flakes - gate on presence and read server logs [testing] [realtime]
+
+- **Trigger:** a multi-client chat-sync E2E flaked on "message not visible" and the first instinct was to raise `toBeVisible` timeouts or add waits; the user correctly rejected this ("it's not a timeout issue").
+- **Rule:** when a cross-user E2E assertion flakes, first gate the assertion on an observable precondition (peer visible in the members panel), then diff the signaling-server logs of a passing vs failing run (`joined server`, `user_joined`, `user_left`, `Removing dead connection`) before touching any timeout.
+- **Why:** the flake was a server race — `identify` + `join_server` arriving in one TCP segment were processed concurrently, the join was dropped as unauthenticated, and room membership silently vanished; no timeout can fix a message that is never broadcast. Fixed by serializing per-connection message handling in `server/src/websocket/handler.ts`.
+- **Example:** failing run showed one `joined server` for Ludde then `user_left` on sibling-client close; passing run showed two. `expectServerPeerVisible(page, displayName)` in `e2e/helpers/multi-device-session.ts` is the presence gate.
+
 ### When renaming an Angular route, sweep every navigate/url-match/doc reference [routing]
 
 - **Trigger:** the find-servers route was renamed `/search` → `/servers` in `app.routes.ts`, but `servers-rail.component.ts` still called `router.navigate(['/search'])` (leave-server) and matched `startsWith('/search')` for the user-bar visibility signal, throwing `NG04002: 'search'` on leave and never showing the user-bar on the discovery page.
@@ -32,12 +88,12 @@ Durable rules for AI agents working on this project. Read this file at session s
 - **Why:** `router.navigate` to a non-existent path raises `NG04002` and aborts navigation, and stale `startsWith` matches silently break route-derived UI state — neither is caught by the build (string literals) and there was no `servers-rail` spec to catch it.
 - **Example:** fixed `isOnServers`/`router.navigate(['/servers'])` in `servers-rail.component.{ts,html}`; canonical post-leave/discovery route is `/servers` (`FindServersComponent`), matching `DashboardComponent`'s `router.navigate(['/servers'])`.
 
-### Server discovery (featured/trending) must fan out across all online endpoints like search [server-directory]
+### Server discovery must fan out across all endpoints and self-heal on 404 — never hardcode a host capability blocklist [server-directory]
 
-- **Trigger:** the `/servers` (find-servers) page showed no servers by default but found them as soon as the user typed in the search box. Discovery (`getDiscoveryServers`) queried only the *active* endpoint via `getApiBaseUrl()`, and when that endpoint is a discovery-unsupported production host (`signal.toju.app` / `signal-sweden.toju.app` in `DISCOVERY_UNSUPPORTED_HOSTS`) it short-circuited to `[]`; search meanwhile fans out across every online endpoint, so typing surfaced the servers that lived on other endpoints (e.g. localhost).
+- **Trigger:** the dashboard "Popular Servers" and `/servers` discovery view were empty for fresh users until they typed a search. The first fix added a static `DISCOVERY_UNSUPPORTED_HOSTS` blocklist (`signal.toju.app` / `signal-sweden.toju.app`) that short-circuited discovery to `[]`; the production hosts later shipped the `/featured` + `/trending` routes (verified `curl` → 200 with servers), so the stale blocklist kept blocking exactly the default endpoints a fresh account has while ungated search still surfaced them.
-- **Rule:** make `getFeaturedServers`/`getTrendingServers` fan out across `getSearchableEndpoints()` with `forkJoin` + `deduplicateById` (mirroring all-endpoint search), and apply the `endpointSupportsServerDiscovery` gate *per endpoint* (skip → `[]`) instead of short-circuiting the whole request on the active endpoint.
+- **Rule:** discovery (`getFeaturedServers`/`getTrendingServers`) must fan out across `getSearchableEndpoints()` with `forkJoin` + `deduplicateById` (mirroring all-endpoint search), and detect capability *at runtime* — on a `404` from `/api/servers/{featured,trending}`, fall back per-endpoint to the public `GET /api/servers` listing (`fetchPublicServerListForDiscovery`) instead of returning `[]`. Do not maintain a hardcoded list of hosts that "don't support" a route; it goes stale silently and the build can't catch it.
-- **Why:** the empty-query find-servers view renders discovery sections, not search results, so any divergence between discovery's endpoint set and search's endpoint set makes the default view look broken while search works.
+- **Why:** legacy servers resolve `/featured` as `/servers/:id` and answer 404, so a 404→fallback keeps the default view populated everywhere without a blocklist; the empty-query view renders discovery sections (not search results), so any divergence between discovery and search makes it look broken while search works.
-- **Example:** `getDiscoveryServers` + `fetchDiscoveryFromEndpoint` in `server-directory-api.service.ts`; verified the live server returns 12 featured/12 trending while the active production host is gated out client-side.
+- **Example:** `fetchDiscoveryFromEndpoint` + `fetchPublicServerListForDiscovery` in `server-directory-api.service.ts`; `e2e/tests/servers/server-discovery-default.spec.ts` proves a fresh account sees Popular Servers without searching AND that route-intercepting `/featured`+`/trending` to 404 still populates it via the fallback.

Per-user **library membership** lives separately in `localStorage` (`metoyou_custom_emoji_saved:<userId>`), which is what keeps the picker user-bound even on a shared client database.

+## App icon & splash (Android brand assets)
+
+The Capacitor shell must ship the Toju brand mark, not the stock Ionic/Capacitor placeholder. Brand resources are generated from `images/icon-new-rounded.png` (circular cat-on-purple disc) into `toju-app/android/app/src/main/res/`:
+
+```bash
+npm run cap:assets:android   # → tools/generate-android-app-icons.mjs (uses sharp)
+```
+
+This produces, for every density (`mdpi … xxxhdpi`):
+
+- `mipmap-*/ic_launcher.png` + `ic_launcher_round.png` — legacy launcher bitmaps (the brand disc inset to the adaptive-icon safe zone so circular masks do not clip the cat face).
+- `mipmap-*/ic_launcher_foreground.png` — adaptive foreground centred at **66/108** of the 108dp canvas (Android safe zone); the adaptive layers in `mipmap-anydpi-v26/ic_launcher*.xml` reference `@mipmap/ic_launcher_foreground` with `@color/ic_launcher_background` brand purple behind it.
+- `values/ic_launcher_background.xml` — adaptive background colour set to the **brand purple `#4A217A`**, not stock white.
+- `drawable*/splash.png` (port + land per density, plus the base) — brand mark centred at **32%** of the shorter splash edge on a purple field (down from 40% so the cat face is not cropped on launch).
+
+Invariants are encoded in `toju-app/src/app/infrastructure/mobile/logic/mobile-android-launcher-icon.rules.ts` (required file set, brand background colour, and the SHA-256 of every stock Capacitor placeholder that must never reappear). Coverage:
+
+- Unit: `mobile-android-launcher-icon.rules.spec.ts` — asserts every density is present, no resource matches a stock placeholder hash, and the adaptive background is the brand purple.
+- E2E: `e2e/tests/mobile/android-app-icon.spec.ts` — same contract plus pixel checks (launcher ring is purple, centre is the white cat; splash corner is purple, centre is the cat). Deterministic; no emulator.
+
+Re-run `npm run cap:assets:android` whenever `images/icon-new-rounded.png` changes; `npm run cap:sync` is **not** needed (resources live in the native project, not `webDir`).

 - `capacitor.config.ts` sets `plugins.SystemBars.insetsHandling: 'css'` so Android WebView versions that mis-report `env(safe-area-inset-*)` still receive correct insets.
-- Global `styles.scss` applies inset padding on `html` (with `env()` fallback) and sizes `app-root` to `height: 100%` so content stays below the status bar and above the navigation bar in edge-to-edge mode.

These read `--safe-area-inset-*` with `env()` fallback so routed pages, settings, context menus, and profile cards stay below the status bar and above the navigation bar.

 - Every database schema change ships as a TypeORM **migration**; the live database is never mutated outside the migration system.
 - WebSocket **Envelope** types are defined once in `src/websocket/types.ts` and **must** stay structurally compatible with `toju-app/src/app/shared-kernel/signaling-contracts.ts` — drift between the two is a wire-protocol break.
+- WebSocket messages from a single connection are processed **strictly in arrival order** (`handleWebSocketMessage` chains them per connection id). Concurrent handling lets a `join_server` overtake a still-awaiting `identify` and silently drop room membership.
 - User-supplied URLs are **never** fetched without going through `ssrf-guard.ts`.
 - Secrets (klipy API key, OAuth tokens, signing keys) live in `data/variables.json` or environment variables — never in code, never in logs.

+### Transfer integrity invariants
+
+Concurrent triggers (file-announce, message sync, peer connect) can race to request the same file, and a sender can receive duplicate `file-request`s for the same attachment. The transfer service enforces these invariants so duplicate streams can never corrupt a download (regression: receivers used to finalize after only the first chunks):
+
+- **Requester:** `requestFromAnyPeer` marks the request pending *synchronously* before any async work, so the manager's `hasPendingRequest` gate closes the double-request race window.
+- **Sender:** `handleFileRequest` / `fulfillRequestWithFile` track active outbound streams per `(messageId, fileId, peerId)` and ignore duplicate requests while a stream is in flight. A fresh `file-request` clears any earlier `file-cancel` marker from that peer.
+- **Receiver:** chunk buffers are dense (`Array.from({ length: total })`, never sparse `new Array(total)`); a chunk index that is already buffered is ignored entirely and never counts toward `receivedBytes`; a transfer finalizes only when *every* chunk index is present — byte counters are never a substitute for chunk completeness. Assembly state is released only after the attachment is marked `available`, and chunks arriving for an already-available attachment are dropped.
+
 ### Failure handling
 
 If the sender cannot find the file, it replies with `file-not-found`. The transfer service then tries the next connected peer that has announced the same attachment. Either side can send `file-cancel` to abort a transfer in progress.

 An optional experimental VLC.js adapter can be enabled from General settings. When enabled, unsupported downloaded audio/video files show a manual Play action that lazy-loads `/vlcjs/metoyou-vlc-player.js`. The runtime is intentionally isolated in the experimental media domain and is not part of the default attachment path.
 
+## Ownership and the "Shared from your device" label
+
+`uploaderPeerId` is the **user** id of whoever uploaded the file, not a per-device id. It is intentionally stable across a user's devices so an uploader can recognise their own attachments after sync. Because of that, "did *this* device upload it?" and "does *this* device hold the bytes?" are two different questions, and the UI must key the *sharing* affordance off the latter.
+
+`attachment-sharing.rules.ts` makes this explicit:
+
+- `isUploaderUser(attachment, currentUserId)` — the current user is the uploader (same user, any device).
+- `deviceHasLocalCopy(attachment)` — this device physically holds the bytes (`available` + a blob `objectUrl`, or a non-empty `savedPath`/`filePath`). Synced metadata alone does not count, because P2P/account sync strips local paths.
+- `isSharingFromThisDevice(attachment, currentUserId)` — `isUploaderUser && deviceHasLocalCopy`. Only this returns the "Shared from your device" state.
+
+The chat message item renders "Shared from your device" (and hides the request/download affordance) **only** when `isSharingFromThisDevice` is true. A second device of the same user that merely synced the message metadata is the uploader-user but holds no local copy, so it falls back to the normal recipient flow (request/download) instead of falsely claiming ownership and blocking the file (regression: the old check used `uploaderPeerId === currentUserId` and so claimed ownership on every device of the uploader). The transfer service uses the same rule to decide whether a no-peers failure should read "your original upload is missing" (sharing device) or "no connected peers" (any other device).
+
 ## Persistence
 
+Attachment file persistence is platform-agnostic. `AttachmentStorageService` owns the `server/<room>/<bucket>` and `direct-messages/...` path layout and delegates the raw byte IO to a pluggable `AttachmentFileStore` chosen by `PlatformService` (mirroring how `DatabaseService` picks a DB backend):
+
+- **Electron** (`ElectronAttachmentFileStore`): real on-disk files via `window.electronAPI`; supports chunked reads and streamed (append) receive; `maxPersistableBytes = Infinity`.
+- **Capacitor / Android** (`CapacitorAttachmentFileStore`): native `@capacitor/filesystem` under `Directory.Data` (lazy-loaded per the LESSONS rule); inline media is displayed through a `convertFileSrc` webview URL instead of a renderer `Blob`, avoiding large-media memory pressure on mobile; `maxPersistableBytes = Infinity`.
+- **Browser** (`BrowserAttachmentFileStore`): a per-user IndexedDB virtual filesystem (`metoyou-attachment-files::<userId>`, store `files` keyed by path), so a user's own uploads and downloaded media survive reloads; `maxPersistableBytes = MAX_BROWSER_INLINE_MEDIA_SIZE_BYTES` (50 MB) so very large media stays peer/in-memory only.
+
+The transfer service consults `attachmentStorage.canStreamToDisk()` / `canPersistSize(size)` so the browser cap degrades gracefully (oversized media is kept in memory / peer-served instead of failing the disk path), and streamed receive only runs on stores with a real append primitive.
+
 On Electron, local audio/video uploads are played through the original filesystem path when Electron exposes one, and received audio/video downloads are appended to an app-data file as chunks arrive. Completed audio/video downloads are then played through a file-backed media URL instead of being reloaded into a renderer `Blob`, which avoids full-file renderer memory pressure during download, startup restore, and playback. The storage path for downloaded server-room files is resolved per room and bucket:

 Room and conversation names are sanitised to remove filesystem-unsafe characters. The bucket is `video`, `audio`, `image`, or `files` depending on the attachment type. The original filename is kept in attachment metadata for display and downloads, but the stored file uses the attachment ID plus the original extension so two uploads with the same visible name do not overwrite each other.
 
-`AttachmentPersistenceService` handles startup migration from an older localStorage-based format into the database, and restores attachment metadata from the DB on init. On Electron, saved audio/video records are restored as file-backed URLs; other restored files still need their bytes loaded when a `Blob` URL is required. On browser builds, files stay in memory only.
+`AttachmentPersistenceService` handles startup migration from an older localStorage-based format into the database, and restores attachment metadata from the DB on init. On restore, `ensureInlineDisplayObjectUrl` resolves the stored path and, when the active store exposes a directly loadable URL (`providesInlineObjectUrl`, i.e. Capacitor), uses that URL as-is; otherwise it rebuilds a `Blob` from the stored bytes (Electron via chunked reads, browser via whole-file read with the correct MIME). Because the browser store persists bytes to IndexedDB, sent and received files are remembered across reload/restart on every platform.
