+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+vojo@vojo.chat.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

 ## Getting started
-Web app is available at https://app.cinny.in and gets updated on each new release. The `dev` branch is continuously deployed at https://dev.cinny.in but keep in mind that it could have things broken.
 
-You can also download our desktop app from [cinny-desktop repository](https://github.com/cinnyapp/cinny-desktop).
+The web app is available at [vojo.chat](https://vojo.chat).
 
-To host Cinny on your own, download tarball of the app from [GitHub release](https://github.com/cinnyapp/cinny/releases/latest).
+## Self-hosting
-You can serve the application with a webserver of your choice by simply copying `dist/` directory to the webroot. 
-To set default Homeserver on login and register page, place a customized [`config.json`](config.json) in webroot of your choice.
 
-Alternatively you can just pull the [DockerHub image](https://hub.docker.com/r/ajbura/cinny) by:

+ * NOT used — every Synapse the Vojo audience runs against (vanilla, v1.11+
+ * by deployment policy, see docs/ai/server-side.md) speaks auth media.
+ * Removing the legacy fallback keeps the loader off the deprecated path
+ * and avoids leaking the access token to a server route that doesn't
+ * require it.
+ *
+ * Concurrency: each MXC URL is fetched at most once concurrently — the
+ * `inFlight` set short-circuits duplicate requests from rapid
+ * append-rebuild cycles on the same conversation. Loads happen on a
+ * shared 4-thread pool; bigger than 1 so 5 senders in a group chat can
+ * load in parallel, capped to keep socket pressure under the typical
+ * mobile network budget.
+ *
+ * Two entry points:
+ *   - {@link #loadAllWithTimeout}: synchronous wait, used by the render
+ *     path to populate the cache before building the MessagingStyle so the
+ *     first post already has avatars. Timeout-bounded to keep FCM thread
+ *     responsive (Android budgets ~10s; we use 800 ms).
+ *   - {@link #prefetch}: fire-and-forget, used for warm-up scenarios.
+ *     Not currently called but kept for the room-metadata bridge to
+ *     eventually warm the cache on visibility resume.

+ *   - On 2xx: remove the tombstone — receiver path succeeded, no flusher work.
+ *   - On non-2xx or exception: leave tombstone; flusher drains on next resume.
+ *
+ * Null-session edge case (fresh reinstall + first push before first login):
+ * we cannot send the decline at all — there's no access token, and the
+ * JS-path can't cover us either (a logged-out client has no Matrix session
+ * to call sendRtcDecline against). Cancelling the notification is the only
+ * feedback we can give; leaving the ring would trap the user on a call they
+ * can't accept or decline until the A-side times out.
+ *
+ * Note on idempotency: the flusher's retry generates a new txnId, so on a
+ * split-success-fail sequence (receiver HTTP timed out, flusher succeeds)
+ * we may land two {@code m.call.decline} events in the timeline with the

+ * Posts {@code POST /_matrix/client/v3/rooms/{roomId}/receipt/m.read/{eventId}}
+ * using the access token saved by the polling lifecycle in
+ * {@code vojo_poll_state} SharedPreferences (same storage VojoPollWorker uses;
+ * keeps the credential lifecycle single-sourced). After a successful 2xx the
+ * per-room MessagingStyle notification is dismissed and the
+ * {@link RoomMessageCache} is cleared so the next push to that room starts a
+ * fresh conversation rather than re-appending to the prior history.
+ *
+ * Dismiss policy: OPTIMISTIC. The per-room notification is dismissed
+ * synchronously in onReceive — before the HTTP receipt PUT is even
+ * attempted — so the user sees instant feedback. The async receipt POST
+ * happens on a worker thread afterwards. This mirrors element-android's
+ * NotificationBroadcastReceiver pattern and matches the user's mental
+ * model ("I tapped, it should disappear immediately").
+ *
+ * Failure mode: on any non-2xx or thrown exception we accept that the
+ * server-side read receipt did not land. We do NOT re-post the
+ * notification or implement a flusher because:
+ *   - the next room open from the JS app issues a fresh read-receipt
+ *     for the latest visible event, catching up the server state
+ *   - the in-app read-marker logic is the authoritative path; this
+ *     receiver is a convenience for the shade-tap shortcut
+ *   - accumulating tombstones in prefs (the CallDeclineReceiver pattern)
+ *     would risk leaking historical eventIds the JS side would re-issue
+ *     on app resume anyway
+ *
+ * Null-credential edge case (fresh install + first push before any
+ * saveSession bridge): no token to use, we still dismiss the notification
+ * locally so the user isn't stuck looking at a "stuck" Mark-as-read
+ * button. The next room open from JS covers the server view.

+ * via {@code pickPendingShare()} (or reacts to via the {@code shareReceived}
+ * event when the app was already in the foreground).
+ *
+ * Cold-start flow:
+ *   1. Share-sheet → Vojo → MainActivity.onCreate → super.onCreate runs
+ *      BridgeActivity.load(), which itself calls bridge.onNewIntent(getIntent())
+ *      and fans the intent out to every plugin's handleOnNewIntent. So
+ *      cold-start and warm-start share the SAME entry point — we don't
+ *      double-process via handleOnStart.
+ *   2. captureFromIntent copies payload bytes into the app cache and stashes
+ *      the result in {@link #pendingShare}.
+ *   3. JS booting up (Matrix client ready, user logged in) calls
+ *      pickPendingShare(); receives the JSON; opens the room-picker UI. The
+ *      shareReceived event fired here is dropped silently because no JS
+ *      listener is attached yet — that's fine, pickPendingShare drains the
+ *      slot regardless.
+ *
+ * Warm flow (app already running):
+ *   1. Share-sheet → MainActivity.onNewIntent → BridgeActivity forwards to
+ *      plugin.handleOnNewIntent(intent).
+ *   2. We re-capture the payload AND emit {@code shareReceived} so JS can
+ *      open the picker without polling.
+ *
+ * Why we copy to cache instead of handing JS a content:// URI:
+ *   - WebView fetch() rejects content:// schemes outright, and
+ *     `Capacitor.convertFileSrc()` only works on file paths.
+ *   - The originating app holds the read-grant only for the lifetime of the
+ *     launching task; routing the URI through JS+picker+RoomInput would race
+ *     that grant on Android 14+.
+ *   - Copying into our own cache means the share is self-contained: even if
+ *     the user backgrounds Vojo for hours before picking a chat, the bytes
+ *     are still there. We schedule no cleanup of our own — Android's cache
+ *     eviction handles long-tail garbage.

+/**
+ * Periodic poll of `/_matrix/client/v3/notifications` as a fallback delivery
+ * channel for users whose network blocks FCM (mtalk.google.com:5228) — the
+ * ~5% slice on whitelist intranets (corporate / school / government) that
+ * otherwise receive zero pushes.
+ *
+ * Scheduling: enqueued from PollingPlugin.schedule() with a 15-minute period
+ * (Android's minimum for PeriodicWorkRequest) and CONNECTED network constraint.
+ * Cancelled via PollingPlugin.cancel() on logout / push disable.
+ *
+ * Credentials: read from SharedPreferences (saved by the JS side through
+ * PollingPlugin.saveSession). Vanilla Synapse (no MAS/OIDC) issues
+ * non-expiring access tokens; we do not implement refresh-token flow here.
+ * If a 401 ever occurs, doWork returns Result.success() — the next foreground
+ * launch re-saves the credentials and polling resumes. Retrying with a stale
+ * token would just waste battery and amplify rate limits.
+ *
+ * Output: messages and invites route through VojoFirebaseMessagingService
+ * .renderMessageNotification (shared with FCM, same notif-id slots →
+ * Android dedupes by replace). RTC ring events route through
+ * .renderMissedCallNotification (always stale by the time we poll — 15-min
+ * cadence vs 30-second ring lifetime), so the user sees "Missed call" instead
+ * of a phantom incoming-call CallStyle for a long-dead ring.
+ *
+ * E2EE caveat: Synapse cannot decrypt event content, so for end-to-end
+ * encrypted rooms the response carries `content.algorithm`+`ciphertext`
+ * with no `body`. The renderer falls through to PushStrings.messageFallback
+ * (i18n "New message") with the room name as title — same UX as the web
+ * Service Worker on encrypted pushes. By design — no key access from the
+ * Worker.
+ *
+ * Dedup is two complementary mechanisms:
+ *   1) A per-poll high-watermark on the latest event ts we've notified.
+ *      Stored as KEY_LAST_SEEN_TS; advances only after a successful render
+ *      (or a foreground-skipped event the user already saw in-app). Worker
+ *      stops walking within a run as soon as it hits ts strictly less than
+ *      watermark — newest-first ordering guarantees the rest are also
+ *      older. Same-ts events fall through to the secondary filters because
+ *      multiple events can share a millisecond.
+ *   2) NotificationDedup — a shared cross-source bounded LRU written by
+ *      every renderer (FCM service after successful nm.notify, this Worker
+ *      after successful render, and the ring-upsert paths at seed time).
+ *      Lets the Worker skip events FCM already delivered even after the
+ *      user dismissed the FCM notification.
+ *
+ * Each fire starts from the HEAD of /notifications (no persistent
+ * pagination cursor — the spec's `next_token` walks BACKWARDS into
+ * history, so a persisted cursor silently drifts off the new events the
+ * next poll should see; see matrix-js-sdk client.ts:5040 for the
+ * reference traversal pattern). When a single fire's backlog exceeds
+ * MAX_PAGES_PER_RUN pages the leftover next_token is saved as
+ * KEY_DRAIN_CURSOR (with the head ts snapshotted in KEY_DRAIN_TARGET_TS)
+ * and resumed on the next run, so big backlogs (>250 events) drain over
+ * consecutive polls without being clipped.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template

+# @vojo/widget-discord
+
+Vojo Discord bridge management widget — mounts inside `/bots/discord`
+in the Vojo client. Mirrors the Telegram widget contract; protocol
+specifics differ because mautrix-discord runs on the **legacy** mautrix
+command framework, not bridgev2 (the Discord bridge had not yet been
+ported to v2 as of January 2026 — see
+https://mau.fi/blog/2026-01-mautrix-release/).
+
+This is **not** a Discord client. It's a small panel that drives the
+mautrix-discord bridge bot (`@discordbot:vojo.chat`) by sending text
+commands in the control DM and rendering the bot's text replies. It
+ships QR-only login (the Discord token-login flow stays accessible via
+chat-fallback for power users).

+
+## Login flow (QR only)
+
+1. Widget sends `!discord login-qr`.
+2. Bridge replies with an `m.image` event whose `body` is a Discord
+   remoteauth URL (`https://discord.com/ra/<token>`). The host driver
+   strips `url`/`file`/`info` so the widget never touches the uploaded
+   PNG bytes — it re-encodes the URL into an SVG QR matrix client-side
+   via `qrcode-generator`.
+3. The user scans the QR with the **Discord mobile app** (Settings →
+   Devices → Scan QR Code). Discord's remoteauth gateway requires the
+   mobile app — desktop Discord and the browser cannot scan.
+4. Bridge redacts the `m.image` event after a successful scan and sends
+   `Successfully logged in as @<username>`.
+5. Widget fires `!discord ping` to pick up the discord snowflake for
+   the connected pill.
+
+If Discord asks for a CAPTCHA, the bridge replies with the standard
+error line plus a hint about token-login. The widget surfaces an amber
+warning suggesting the user retry later or use chat-fallback.
+
+## Status probe
+
+Discord's legacy command system has no `list-logins` API; status is
+queried via `!discord ping`. The four reply variants map to four UI
+states:
+
+- `You're not logged in` → disconnected
+- `You're logged in as @x (\`<id>\`)` → connected
+- `You have a Discord token stored, but are not connected for some reason 🤔` → connected_dead (token_stored)
+- `You're logged in, but the Discord connection seems to be dead 💥` → connected_dead (connection_dead)
+
+`connected_dead` exposes a «Переподключиться» card that sends
+`!discord reconnect`. `disconnect` is recognised for chat-fallback
+typists but never sent by the widget.
+
+## Local development
+
+Same overlay mechanism as the Telegram widget — create
+`config.local.json` at the project root (gitignored) with a `bots[]`
+entry overriding the discord widget's `experience.url` to your local
+dev server:
+
+```bash
+# one-time: install widget deps
+cd apps/widget-discord && npm install
+
+# config.local.json (gitignored) at the project root
+cat > /home/ubuntu/projects/vojo/cinny/config.local.json <<'JSON'
+{
+  "bots": [
+    {
+      "id": "discord",
+      "experience": {
+        "type": "matrix-widget",
+        "url": "http://localhost:8082/",
+        "commandPrefix": "!discord"
+      }
+    }
+  ]
+}
+JSON
+```
+
+`http://localhost:*` URLs pass the host's URL validator only in dev
+builds — see `src/app/features/bots/catalog.ts` `import.meta.env.DEV`
+branch. Production builds drop the branch via Vite's dead-code
+elimination AND enforce an origin allowlist (`PROD_WIDGET_ORIGINS`).
+
+Run both servers:
+
+```bash
+# terminal 1 — widget on :8082 with HMR
+cd apps/widget-discord && npm run dev
+
+# terminal 2 — host SPA on :8080
+cd /home/ubuntu/projects/vojo/cinny && npm start
+```
+
+Open `http://localhost:8080/bots/discord`. The Telegram widget on :8081
+can run in parallel with no port conflict.
+
+## Build
+
+```bash
+npm run build
+```
+
+Outputs to `apps/widget-discord/dist/`. Deploy by rsyncing `dist/*` into
+`~/vojo/widgets/discord/` on the production host (Caddy serves this via
+the `widgets.vojo.chat` block).
+
+## Hosting (server-side, runbook)
+
+Pre-requisite: `widgets.vojo.chat` already exists for the Telegram
+widget — only the Caddy `widgets.vojo.chat` block needs a new
+`handle_path` and the docker host needs a new directory.
+
+1. `~/vojo/caddy/Caddyfile` — append to the existing
+   `widgets.vojo.chat { … }` block, beside the Telegram `handle_path`:
+   ```
+   handle_path /discord/* {
+       root * /var/www/widgets/discord
+       try_files {path} /index.html
+       file_server
+   }
+   ```
+2. `mkdir -p ~/vojo/widgets/discord` (placeholder so the bind-mount has
+   something to serve), then `docker compose up -d caddy` (or `reload`).
+3. Verify directly:
+   `curl -I https://widgets.vojo.chat/discord/index.html` should
+   return 200 and the `Content-Security-Policy` header.
+
+## Adding the discord bridge to docker-compose
+
+```yaml
+discord-bridge:
+  image: dock.mau.dev/mautrix/discord:v0.7.6
+  restart: unless-stopped
+  volumes:
+    - ./mautrix-discord:/data
+```
+
+Then `~/vojo/synapse/homeserver.yaml` needs the discord registration
+file added to `app_service_config_files`:
+
+```yaml
+app_service_config_files:
+  - /data/telegram-registration.yaml
+  - /data/discord-registration.yaml
+```
+
+The bridge's `command_prefix` defaults to `!discord` — keep it that
+way so it matches the widget's `experience.commandPrefix`. If you
+override it in `mautrix-discord/config.yaml`, mirror the override in
+`/config.json`.
+
+## Capacitor (Android)
+
+`capacitor.config.ts` already allow-navigates `widgets.vojo.chat` for
+the Telegram widget; no further change needed.
+
+## Capability contract
+
+The widget requests EXACTLY this set (matches the host's
+`BotWidgetDriver.getBotWidgetCapabilities`):
+
+```
+org.matrix.msc2762.timeline:<roomId>
+org.matrix.msc2762.send.event:m.room.message#m.text
+org.matrix.msc2762.receive.event:m.room.message#m.text
+org.matrix.msc2762.receive.event:m.room.message#m.notice
+org.matrix.msc2762.receive.event:m.room.message#m.image
+org.matrix.msc2762.receive.event:m.room.redaction
+org.matrix.msc2762.receive.state_event:m.room.member
+```
+
+`m.image` is the QR carrier; `m.room.redaction` signals the bridge
+consumed the QR after a successful scan. The host sanitizer strips
+`url`/`file`/`info` from `m.image` content, so only the QR URL string
+inside `body` survives the boundary.
