+## Plugins
+
+hyprcrd has a drop-in plugin system. A plugin is just a folder under `public/plugins/` with a `plugin.json` manifest. The core scans the directory at startup, loads each plugin's CSS/JS/HTML, and the plugin self-registers against `window.hyprcrd`. Plugins are entirely optional — removing a plugin folder removes the feature, with no code changes anywhere else.
+
+### Bundled plugins
+
+- **`canvas/`** — ASCII art canvas editor. Adds a toolbar button + ` ```ascii ` fenced block. Draw with brush, line, rectangle, ellipse, fill, and text tools using a monospace character grid.
+- **`tests/`** — UI + state test runner (40+ test files). Loaded only when `?test` is in the URL or `Ctrl+Shift+T` is pressed, so production users pay no cost for it.
+
+### Plugin layout
+

+├── myplugin.js     # Entry point (loaded as ES module)
+├── myplugin.css    # Optional styles
+├── myplugin.html   # Optional HTML fragment (overlays, modals, etc.)
+└── backend.php     # Optional PHP hooks
+```
+
+**`plugin.json`:**
+
+```json
+{
+    "name": "myplugin",
+    "version": "1.0.0",
+    "description": "What this plugin does",
+    "frontend": {
+        "js":   ["myplugin.js"],
+        "css":  ["myplugin.css"],
+        "html": ["myplugin.html"]
+    },
+    "backend": "backend.php"
+}
+```
+
+### Plugin API (`window.hyprcrd`)
+
+Loaded synchronously before any module, so plugins can register handlers immediately:
+
+| Namespace | Methods | Purpose |
+|---|---|---|
+| `hyprcrd.editor` | `registerCommand(name, fn)`, `getCommand(name)`, `api.{body, insertMd, updatePreview}` | Add toolbar commands. The `data-md="<name>"` button dispatches to the registered handler. `api` is set after the editor initializes. |
+| `hyprcrd.markdown` | `registerFencedBlock(lang, fn)`, `registerPreProcessor(fn)`, `registerPostProcessor(fn)` | Add ` ```<lang> ` block renderers (returns HTML, passes through DOMPurify). Pre/post processors run on the source/HTML around `marked.parse()`. |
+| `hyprcrd.hooks` | `on(name, fn)`, `off(name, fn)`, `emit(name, data)` | Generic event bus. Use for cross-plugin or core→plugin signaling. |
+| `hyprcrd.util` | `$(idOrSel)`, `$$(sel)`, `esc(s)` | Lightweight DOM/escape helpers so plugins don't need to import core modules. |
+| `hyprcrd.registerPlugin(meta)` | — | Register the plugin's metadata for introspection. |
+
+### Minimal plugin example
+
+`public/plugins/hello/plugin.json`:
+
+```json
+{
+    "name": "hello",
+    "version": "1.0.0",
+    "description": "Inserts a greeting",
+    "frontend": { "js": ["hello.js"] }
+}
+```
+
+`public/plugins/hello/hello.js`:
+
+```js
+const h = window.hyprcrd;
+
+h.editor.registerCommand('hello', () => {
+    h.editor.api.insertMd('Hello, world! ', '', '');
+});
+
+// Inject a toolbar button
+const btn = document.createElement('button');
+btn.dataset.md = 'hello';
+btn.className = 'toolbar-btn';
+btn.title = 'Hello';
+btn.textContent = '👋';
+document.getElementById('md-toolbar').appendChild(btn);
+
+h.registerPlugin({ name: 'hello', version: '1.0.0' });
+```
+
+That's the entire plugin. Drop the folder in, reload, the button appears.
+
+### Backend hooks (PHP)
+
+If a plugin needs server-side code, set `"backend": "backend.php"` in the manifest. The file is `require_once`'d during bootstrap. Backend plugins can use `PluginManager::instance()->addToSlot('slot-name', '<html>')` to inject HTML into named slots in `index.php` (e.g. `md-toolbar`).
+
+### Removing a plugin
+
+```bash
+rm -rf public/plugins/canvas
+```
+
+That's it. The toolbar button, overlay, CSS, and markdown handler all disappear together. The core has no awareness of any specific plugin.

-From inside the hyprcrd container, the relay is reachable at `http://relay:80`.
+### Setup workflow
 
-### Setup
+1. Open the relay URL **from a desktop browser** — the setup wizard
+   is desktop-friendly
+2. Create the first **admin** account: username + password (UI login)
+   + shared secret (client encryption)
+3. As admin, click the **users** tab and create accounts for any
+   additional users you want to give relay access to
+4. Each user enters their credentials in their own hyprcrd:
+   **Settings → Relay** → relay URL + username + shared secret
+5. To send a card from one tenant to another, use the relay UI's
+   compose form (recipient picker) — or push cards from hyprcrd
 
-1. Open the relay URL, set a **password** (for UI login) and a **shared secret** (for encryption)
-2. In hyprcrd: **Settings > Relay** — enter the relay URL and the same shared secret
-3. Click **save**
+### How it works (high level)
 
-### How it works
-
-- **Mobile inbox**: type a note on the relay UI, it arrives as a card with `#inbox` tag
-- **Push to relay**: right-click any card → "push to relay" — other instances pick it up on next poll
-- Messages are encrypted client-side (AES-256-CBC) before sending to the relay
-- The relay only stores ciphertext — it cannot read your messages
-- hyprcrd polls the relay every 45 seconds in the background
-- Messages are kept on the relay for 24 hours, then auto-deleted
-- Cards pushed from the same instance are not re-imported
-- Enter to send, Shift+Enter for newline
+- **Per-tenant inboxes**: each user only sees their own messages
+- **Cross-tenant routing**: send a card to another tenant on the same
+  relay; the relay decrypts with the sender's secret, re-encrypts with
+  a shared inter-tenant key for storage, then re-encrypts with the
+  recipient's secret on delivery
+- **At-rest encryption**: every sensitive value in the DB (tenant
+  secrets, the inter-tenant key, message bodies) is encrypted. The
+  master key lives outside the DB in a chmod-600 file
+- **24-hour ephemeral**: messages and attachments auto-delete after a
+  day. Cards extracted in hyprcrd are the long-term store
+- **Future: end-to-end encrypted chat** between tenants is planned and
+  will require per-pair key exchange — see `relay/README.md` for the
+  roadmap
 
 ### Relay Security
 
-- Separate password (UI login) and shared secret (API + encryption)
-- Bcrypt hashing for both credentials
-- Rate-limited login (5 attempts/minute)
-- AES-256-CBC client-side encryption — relay never sees plaintext
+- Per-tenant bcrypt-hashed passwords + secrets
+- Master key encryption for tenant secrets and the inter-tenant key
+  at rest
+- HttpOnly + SameSite=Strict session cookies
+- Rate-limited login (5 attempts/minute per IP)
+- AES-256-CBC for all message encryption
 - Security headers (X-Frame-Options, HSTS, X-Content-Type-Options)
-- SQLite database blocked from direct download via `.htaccess`
-- Request size limited to 256KB
+- `data/` directory blocked from direct download via `.htaccess`
+- Request size limited to 256KB (15MB for attachments)
+- Last-admin protection prevents accidental lockout
+
+For the full security model (including what's NOT protected and the
+roadmap to strict E2E for chat), see [`relay/README.md`](relay/README.md).
+
+### Migrating from the old single-tenant relay
+
+When you upgrade an existing relay installation, the new code automatically
+detects the legacy schema and drops the old `messages` and `attachments`
+tables (the data is 24h-ephemeral anyway). The setup wizard appears on
+your next visit. You'll need to:
+1. Run through the desktop setup wizard to create the first admin
+2. Recreate any other tenant accounts that need access
+3. On every connected hyprcrd, update **Settings → Relay** to add the
+   new **username** field and the new shared secret
+
+The old `relay_key` was bcrypt-hashed and cannot be recovered, so all
+client secrets need to be reissued.

+# hyprcrd — Electron Desktop App
+
+Wraps the PHP backend in an Electron shell. A static PHP binary is bundled
+per platform so users don't need PHP installed.
+
+## How it works
+
+1. On launch, the app starts PHP's built-in server on a random port (`127.0.0.1`)
+2. `router.php` replaces Apache's `.htaccess` rewrite rules
+3. A `BrowserWindow` loads `http://127.0.0.1:<port>/`
+4. On quit, the PHP process is killed cleanly
+
+Data is stored in `data/hyprcrd.db` (SQLite), relative to the project root
+(dev) or inside the app's `resources/` directory (packaged).
+
+## Development
+
+```bash
+cd electron
+npm install
+npm start          # launches the app using system or bundled PHP
+```
+
+Requires PHP 8.1+ with `pdo_sqlite` and `zip` extensions — either on
+the system PATH or as a static binary in `php-bin/<platform>/`.
+
+## Bundling PHP
+
+Static PHP binaries are not checked into git. Fetch them before building:
+
+```bash
+./fetch-php.sh     # downloads ~20MB per platform from static-php-cli
+```
+
+Or place them manually (see `php-bin/README.md` for sources):
+
+    php-bin/linux/php
+    php-bin/darwin/php
+    php-bin/win32/php.exe
+
+The app prefers the bundled binary. If none is found, it falls back to
+system PHP. If neither exists, a dialog tells the user what to install.
+
+## Building distributables
+
+```bash
+npm run dist
+```
+
+Uses `electron-builder`. Output:
+
+| Platform | Format   | Location          |
+|----------|----------|-------------------|
+| macOS    | `.dmg`   | `dist/`           |

+installation.
+
+## Download
+

+(look for `php-8.3-*-cli` assets). Required extensions: pdo_sqlite, zip, session.
+
+    linux/php       — x86_64 Linux ELF binary
+    darwin/php      — macOS universal binary (arm64 + x86_64)
+    win32/php.exe   — Windows PE binary
+
+## Quick fetch (Linux example)
+
+    curl -L -o linux/php \

+├── Disable mechanism

+│   ├── Disabled plugins are skipped in cssLinks, htmlFragments, scriptTags, AND loadBackends
+│   ├── Toggling requires page reload (already-loaded code can't unload)
+│   └── Reload notice in plugins panel; dirtyAfterToggle flag persists until reload
+│
+├── Conventions
+│   ├── Plugins NEVER import from core modules. Use window.hyprcrd globals only.
+│   ├── Plugin JS is ES module (loaded as type="module") so import/export works WITHIN the plugin
+│   ├── Plugin self-registration happens at module top level (no init function needed)
+│   ├── Plugin DOM injection should idempotently check if element already exists
+│   │   (canvas: btn.querySelector('[data-md="asciiart"]') guard)
+│   ├── If a plugin needs DOM that may not exist yet (e.g. injectToolbarButton),
+│   │   wrap in DOMContentLoaded check OR run immediately if document.readyState !== 'loading'
+│   ├── Plugin schema migrations live in backend.php as IIFE that runs once per request
+│   │   (cheap CREATE TABLE IF NOT EXISTS)

+└── Adding a new plugin (checklist)
+    1. mkdir public/plugins/<name>
+    2. Write plugin.json (name, version, description, frontend.{js,css,html}, backend?)
+    3. If JS: import nothing from core. Use window.hyprcrd.* exclusively.
+    4. If HTML: provide overlay/modal markup. Use IDs prefixed with plugin name to avoid clashes.
+    5. If CSS: scope selectors to plugin-specific classes/IDs.
+    6. If backend: require_once your classes, define helpers in named functions (no closures
+       at top level — they pollute the global scope), register routes via onApiRoute().
+    7. If schema: CREATE TABLE IF NOT EXISTS in an IIFE at top of backend.php.
+    8. If credentials: reuse the vault key encryption pattern (see email/backend.php).
+    9. If settings: hyprcrd.settings.registerTab({...}) at the end of init().
+    10. Test by reloading; check window.hyprcrd.plugins includes your meta entry.
+    11. Verify it can be disabled via settings → plugins (assets must vanish from page source).
+    12. If adding a new core hook is unavoidable, document it HERE before merging.

+## API quick reference (copy-paste safe)
+
+### Register a markdown fenced block
+
+```js
+window.hyprcrd.markdown.registerFencedBlock('mylang', (content, { esc }) => {
+    return `<div class="my-block">${esc(content)}</div>`;
+});
+```
+
+### Register an editor toolbar command
+
+```js
+window.hyprcrd.editor.registerCommand('mycmd', () => {
+    const ed = window.hyprcrd.editor.api;
+    if (!ed) return;  // editor not initialized yet (shouldn't happen on user click)
+    ed.insertMd('<<', '>>', 'placeholder');
+});
+
+// Add a button with data-md="mycmd" to #md-toolbar via JS:
+const btn = document.createElement('button');
+btn.dataset.md = 'mycmd';
+btn.className = 'toolbar-btn';
+btn.innerHTML = '<i class="ph ph-star text-sm"></i>';
+document.getElementById('md-toolbar').appendChild(btn);
+```
+
+### Register a settings tab
+
+```js
+window.hyprcrd.settings.registerTab({
+    id: 'mything',
+    label: 'my thing',
+    icon: 'ph-star',
+    onShow: (panelEl) => {
+        panelEl.innerHTML = `<p>Settings UI here</p>`;
+    },
+});
+
+// Open it programmatically:
+window.hyprcrd.settings.openTab('mything');
+```
+
+### Register a backend API route (in backend.php)
+
+```php
+PluginManager::instance()->onApiRoute(function (string $route, string $method) {
+    if ($route === '/api/myplugin/things' && $method === 'GET') {
+        header('Content-Type: application/json');
+        echo json_encode(['ok' => true]);
+        exit;
+    }
+});
+```
+
+### Make a CSRF-protected API call (frontend)
+
+```js
+const result = await window.hyprcrd.api('api/myplugin/things', {
+    method: 'POST',
+    body: { name: 'foo' },
+});
+```
+
+### Encrypt credentials (in backend.php, reusing the vault key)
+
+```php
+function myEncKey(): string {
+    $db = Database::connect();
+    $vk = $db->query("SELECT value FROM settings WHERE key = 'vault_key'")->fetchColumn();
+    if ($vk) return substr(hash('sha256', $vk), 0, 32);
+    $hash = $db->query("SELECT value FROM settings WHERE key = 'password_hash'")->fetchColumn();
+    return substr(hash('sha256', $hash ?: 'hyprcrd-default-key'), 0, 32);
+}
+function myEncrypt(string $plain): string {
+    $key = myEncKey();
+    $iv = random_bytes(16);
+    $cipher = openssl_encrypt($plain, 'aes-256-cbc', $key, OPENSSL_RAW_DATA, $iv);
+    return base64_encode($iv . $cipher);
+}
+function myDecrypt(string $encoded): string {
+    $key = myEncKey();
+    $raw = base64_decode($encoded);
+    if (!$raw || strlen($raw) < 17) return '';
+    return openssl_decrypt(substr($raw, 16), 'aes-256-cbc', $key, OPENSSL_RAW_DATA, substr($raw, 0, 16)) ?: '';
+}

+# collab-buckets plugin
+
+Collaborative buckets shared between relay tenants. Each bucket has an owner
+and a set of members; membership changes and metadata updates propagate
+through the existing relay. Collab buckets are **first-class rows in the
+normal bucket bar** — the plugin just owns the sync plus an unread
+indicator (red dot + 3-cycle pulse) on any tab that has a fresh update.
+
+**Phase 1 through 5 shipped.** Metadata + membership sync, bucket-bar
+integration, full card sync (create / edit / delete, LWW conflict
+resolution with local Conflicts-bucket stashing, encrypted round-trip
+via the relay's decrypt-reencrypt hop), advisory per-card edit locks
+with a 🔒 badge on cards another user is currently editing,
+bucket-ownership transfer through a members & owner modal, and the
+Phase 5 hardening pass: **"Make collaborative…"** upgrade path for
+existing local buckets, **undo** for local bucket delete/leave,
+**resilient create** via a local outbox that queues intents when the
+relay is unreachable and retries on the next poll, and
+**rate-limiting** on all collab endpoints. Remaining nice-to-haves
+(position propagation, presence, read receipts, inline member picker,
+owner approval flow) are in `TODO.md`.
+
+---
+
+## What it does
+
+- **Create a collab bucket** from the normal `+ Bucket` button in the
+  bucket bar. The plugin intercepts the button click (via
+  `window._collabBucketsCreateDialog`) and shows a modal with an optional
+  "collaborative" checkbox. Unchecked → a regular local bucket, same as
+  before. Checked → reveals a member picker listing all other relay
+  tenants, and the submit path goes through `/api/collab-buckets` instead
+  of the core `/api/buckets`.
+- **See other members' buckets** appear automatically in the bucket bar.
+  Every 30 seconds the plugin polls the relay for a full resync; any new
+  or updated bucket the current user is a member of is mirrored into the
+  main `buckets` table, so the core bar renders it alongside everything
+  else.
+- **Collab tabs are visually distinguished**: the folder icon is swapped
+  for `ph-users-three`, there's a subtle left-edge accent stripe, and the
+  right-click menu's rename / color / delete actions route through the
+  plugin endpoints so changes reach the relay and other members.
+- **Unread state**: brand-new buckets and ones whose `updated_at` exceeds
+  the local `last_seen_at` show a red dot top-right of the tab and pulse 3
+  times on the next render. Clicking the tab triggers `mark-seen` which
+  clears the dot/pulse immediately and persists to the plugin backend.
+
+## Architecture
+
+Two places store bucket state locally:
+
+1. **Main `buckets` table** (core) — gains a `collab_uid` column so collab
+   buckets are indistinguishable from local buckets in the bucket bar,
+   bucket selects, card-to-bucket joins, etc. `collab_uid` is unique and
+   NULL for regular local buckets.
+2. **Plugin `collab_buckets` table** — holds collab-only metadata
+   (`members_json`, `owner_username`, `updated_at`, `last_seen_at`) that
+   the main table doesn't need. On every poll the plugin keeps both
+   tables in sync.

+```
+
+- **Relay is source of truth** for bucket metadata + membership. The two
+  local tables are mirrors that together add `last_seen_at` (unread state,
+  user-specific, never synced).
+- **Full resync every 30 s.** Locally cached buckets that are no longer
+  returned by the relay for this user = we were kicked (or the bucket was
+  deleted); both tables drop them and any cards referencing them fall back
+  to unsorted via `ON DELETE SET NULL`.
+- **LWW per bucket**: every patch bumps `updated_at` on the relay. The
+  local poll only re-saves rows whose `updated_at` actually changed,
+  otherwise it's a no-op and `last_seen_at` is untouched so unread state
+  survives unrelated polls.

+
+| File | Purpose |
+|---|---|
+| `plugin.json` | Plugin manifest (auto-enabled unless listed in `data/plugins.json`) |
+| `backend.php` | Plugin backend: `collab_buckets` plugin table, relay proxy, full-resync poll, mark-seen, + `collabUpsertMainBucket` / `collabDeleteMainBucket` helpers that keep the core `buckets` table in sync |
+| `collab-buckets.js` | Frontend: polling loop, exposes `window._collabBucketsCreateDialog` for the core `+ Bucket` button, MutationObserver on `#bucket-bar` to decorate collab tabs with unread dot + pulse, delegated click handler for mark-seen, helpers for rename / color / delete that core's context menu calls for `collab_uid` buckets |

+| `README.md` | This file |
+| `TODO.md` | Deferred features + Phase 3 roadmap |
+
+### Core-side touchpoints (not in this directory)
+
+| File | What changes |
+|---|---|
+| `src/Database.php` | Migration adds `buckets.collab_uid TEXT` + a unique partial index |
+| `public/index.php` | `api/buckets` GET returns `collab_uid` (via `SELECT *`). `PATCH` only allows `position` on collab buckets (name/color must go through the plugin so other members see them). `DELETE` refuses collab buckets with a 400 pointing to `/api/collab-buckets/{uid}` |
+| `public/js/app.js` | Exposes `window.state = state` so the plugin's observer can read `state.buckets` to resolve `collab_uid` per tab |
+| `public/js/modules/buckets.js` | `+ Bucket` click checks `window._collabBucketsCreateDialog` before falling back to the simple dialog. Rename / color / delete actions check `bucket.collab_uid` and route through `window._collabBucketsPatch` / `_collabBucketsDelete` when set |
+
+Relay-side files (not in this directory, part of the main relay deployment):
+
+| File | Purpose |
+|---|---|
+| `relay/inc/bootstrap.php` | Adds `collab_buckets` + `collab_bucket_members` tables (auto-migrated on first boot) |
+| `relay/inc/routes/collab-buckets.php` | `POST/GET/PATCH/DELETE /api/collab-buckets[/{uid}]` |
+| `relay/index.php` | `require`s the new route file after `chat.php` |
+
+## API (local)
+
+All routes live under `/api/collab-buckets` and are registered via
+`PluginManager::instance()->onApiRoute()`.
+
+| Method | Path | Purpose |
+|---|---|---|
+| `GET` | `/api/collab-buckets` | List local mirror. Each row has `has_unread` computed from `last_seen_at` vs `updated_at`. |
+| `POST` | `/api/collab-buckets` | `{name, color, members[]}` — generates UID, pushes to relay, mirrors local. The creator's own `last_seen_at = now` so the tile isn't unread for them. |
+| `PATCH` | `/api/collab-buckets/{uid}` | `{name?, color?, members?}` — owner-only, proxied to relay. Local row updates on next poll. |
+| `DELETE` | `/api/collab-buckets/{uid}` | Owner → delete; member → leave. Relay decides based on the authenticated caller. |
+| `POST` | `/api/collab-buckets/poll` | Full resync. Drops stale local rows, upserts changed remote rows, preserves `last_seen_at`. |
+| `POST` | `/api/collab-buckets/mark-seen` | `{uid}` — sets `last_seen_at = now` so the dot / pulse clear. |
+| `GET` | `/api/collab-buckets/relay-tenants` | Proxy to relay `/api/tenants` for the member-picker. |
+
+## API (relay)
+
+Exact endpoints the local plugin forwards to. Authentication: the standard
+`X-Relay-User` / `X-Relay-Key` client-API headers that the existing chat and
+messages routes also use.
+
+### Buckets
+
+| Method | Path | Behaviour |
+|---|---|---|
+| `POST` | `/api/collab-buckets` | `{uid, name, color, members: [usernames]}`. Unknown usernames are silently dropped; the owner is always added to the member list regardless of whether they included themselves. |
+| `GET` | `/api/collab-buckets` | Returns all buckets where the caller is a member (owner or otherwise). Each row carries its full member list as `members: [usernames]`. |
+| `PATCH` | `/api/collab-buckets/{uid}` | Owner-only. Member-list replacement is total — pass the full desired list. |
+| `DELETE` | `/api/collab-buckets/{uid}` | Owner → `DELETE` of bucket + memberships (with `action: deleted`). Member → just that one membership row (with `action: left`); the bucket's `updated_at` is bumped so the owner sees the change on next poll. |
+
+### Cards (Phase 3)
+
+| Method | Path | Behaviour |
+|---|---|---|
+| `POST` | `/api/collab-cards` | `{bucket_uid, card_uid, payload}` — upsert. `payload` is a `HYPRCRD-RELAY-V1` envelope encrypted with the sender's client secret. The relay decrypts it with the sender's secret (via `masterDecrypt` of their stored `secret_encrypted`), re-encrypts with the inter-tenant key, stores. Server generates `updated_at` so all clients agree on the authoritative LWW timestamp. Membership-guarded. |
+| `GET` | `/api/collab-cards?since=<ts>` | Pull cards updated since `<ts>` (ISO string from a previous response's `max_updated_at`) across all buckets the caller is a member of. Each row is re-encrypted under the caller's client secret on the way out. Tombstoned rows return with `deleted: true` and no payload. Hard-capped to 1000 cards per response. |
+| `DELETE` | `/api/collab-cards/{bucket_uid}/{card_uid}` | Mark tombstone (not hard-delete) so late pollers still observe the deletion within the 7-day TTL. Membership-guarded. |
+

+);
+
+-- Phase 3: per-card sync state. Attached to the core `cards` table via
+-- card_id FK. `last_push_at` mirrors the updated_at we last sent to the

+-- `last_remote_at` mirrors the updated_at we last applied from the relay.
+CREATE TABLE collab_card_state (
+    card_id INTEGER PRIMARY KEY,
+    relay_uid TEXT NOT NULL,
+    bucket_uid TEXT NOT NULL,
+    last_push_at TEXT,
+    last_remote_at TEXT,
+    FOREIGN KEY (card_id) REFERENCES cards(id) ON DELETE CASCADE
+);
+
+-- Phase 3: deletion outbox. Populated by a BEFORE DELETE trigger on the
+-- cards table; drained in the push phase of the next poll.
+CREATE TABLE collab_tombstones (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    relay_uid TEXT NOT NULL,
+    bucket_uid TEXT NOT NULL,
+    queued_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+`members_json` is a JSON array of usernames — flat and cheap to render.
+Because the relay is the source of truth, we don't need to normalise
+members into a separate local table.
+
+The plugin also creates a BEFORE-DELETE trigger on `cards` that inserts a
+tombstone row whenever a card in a collab bucket is deleted — unless the
+suppress temp table `collab_suppress_outbox` has a row, which the plugin
+sets during the poll's apply phase so remotely-triggered deletes don't
+re-enqueue.
+
+## Schema (relay)
+
+```sql
+CREATE TABLE collab_buckets (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    uid TEXT UNIQUE NOT NULL,
+    owner_id INTEGER NOT NULL,
+    owner_username TEXT NOT NULL,
+    name TEXT NOT NULL,
+    color TEXT NOT NULL DEFAULT '#38bdf8',
+    created_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    updated_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,

+);

+    added_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    PRIMARY KEY (bucket_uid, tenant_id),
+    FOREIGN KEY (tenant_id) REFERENCES tenants(id) ON DELETE CASCADE
+);
+
+-- Phase 3: the actual synced card content. `payload` is the re-encrypted
+-- envelope stored at rest under the inter-tenant key. `deleted = 1`
+-- marks a tombstone; bootstrap.php prunes them after 7 days.
+CREATE TABLE collab_cards (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    bucket_uid TEXT NOT NULL,
+    card_uid TEXT NOT NULL,
+    author_username TEXT NOT NULL,
+    payload TEXT NOT NULL,
+    updated_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    deleted INTEGER NOT NULL DEFAULT 0,
+    UNIQUE (bucket_uid, card_uid)
+);
+```
+
+Owner deletion cascades via `ON DELETE CASCADE` on the `owner_id` FK.
+Member rows are pruned explicitly on leave (or cascade when a tenant is
+deleted outright). `collab_cards` rows belonging to a deleted bucket are
+orphaned but unreachable — the GET query joins `collab_bucket_members`
+and returns nothing for them, so they're effectively gone. Future hardening
+could add a cascade trigger.
+
+## Card sync flow (Phase 3)
+
+Every poll does three things in strict order inside one request:
+
+1. **Drain tombstones.** The `collab_tombstones` outbox table is populated
+   by a BEFORE DELETE trigger on `cards` — whenever a user deletes a card
+   that sits in a collab bucket, the trigger inserts a row `{relay_uid,
+   bucket_uid}` into the outbox. The poll pushes each row to
+   `DELETE /api/collab-cards/{bucket}/{card}` and drops the outbox entry
+   on success. Failed pushes stay queued and retry next poll.
+
+2. **Push dirty cards.** One query finds every card in a collab bucket
+   whose `updated_at` is greater than `collab_card_state.last_push_at`
+   (or never-pushed). Each is encrypted with the local `relay_key` and
+   POSTed to `/api/collab-cards`. On success, `last_push_at` is stamped
+   with the server's returned `updated_at` so the next poll skips it.
+   Cards without a `relay_uid` get one assigned (16 hex chars) and the
+   core `cards.relay_uid` column is updated so the card has a stable
+   cross-tenant identity.
+
+3. **Pull deltas.** `GET /api/collab-cards?since=<stored>` fetches every
+   card updated or tombstoned since the stored marker (core `settings`
+   row `collab_cards_last_remote_at`). For each incoming card:
+   - If `deleted: true` → look up the local card by `relay_uid` and
+     `DELETE` it. The BEFORE DELETE trigger is suppressed via the
+     `collab_suppress_outbox` temp-table flag so it doesn't re-enqueue
+     the tombstone back into the outbox.
+   - Otherwise, decrypt the payload, find the local card by `relay_uid`,
+     and apply LWW (`remote.updated_at > local.updated_at` → overwrite).
+     New cards are INSERTed with `bucket_id` resolved via
+     `buckets.collab_uid`. In both cases `collab_card_state.last_push_at`
+     and `last_remote_at` are set to the remote's `updated_at` so the
+     next push phase doesn't re-send what was just received.
+
+Conflict resolution is strict LWW on `updated_at`. If two users save the
+same card within the same second, the second writer wins; the first
+writer's changes are silently overwritten on their next pull. Phase 4
+adds optional edit-locks to surface the conflict before it happens.
+
+## Unread / pulse state
+
+`has_unread` is computed by the plugin backend on every read of
+`/api/collab-buckets`:
+
+```
+has_unread = (last_seen_at IS NULL) OR (updated_at > last_seen_at)
+```
+
+- **Brand-new bucket** → poll inserts the plugin row with `last_seen_at =
+  NULL` → unread.
+- **Metadata / member change** → relay bumps `updated_at` → poll upserts →
+  `updated_at > last_seen_at` → unread.
+- **Click tab** → `mark-seen` sets `last_seen_at = now` → unread clears on
+  the next render.
+
+The plugin frontend watches `#bucket-bar` via `MutationObserver`. After
+every core re-render, it walks the tabs, looks up each bucket in
+`state.buckets`, and applies `.bucket-tab-collab` plus (if unread) the
+`.pulsing` class and an injected `.collab-tab-dot` element. The pulse
+animation is CSS-driven (`collab-bucket-pulse 1.2s ease-in-out 3`), and
+the JS strips `.pulsing` after 3.7 s so subsequent re-renders don't
+retrigger it mid-cycle.
+
+## Theming
+
+All chrome hooks into the standard design tokens:
+
+- `--ui-radius-button` — tile and button rounding
+- `--ui-radius-modal` — create/edit modal
+- `--ui-radius-input` — form inputs
+- `--ui-shadow-modal` — modal drop shadow
+- `--ui-blur-overlay` — modal backdrop blur
+- `--collab-tile-color` (per-tile) — bucket color, mixed into border, text,
+  hover background, and pulse ring
+
+So a collab tile automatically inherits the currently selected theme and the
+user's design-token choices without any plugin-side theming code.
+
+## Why this shape
+
+- **First-class bucket rows, not a separate UI.** Collab buckets show up
+  exactly where users already look for buckets. No extra header tiles, no
+  second "collab+" button — the existing `+ Bucket` workflow just gains a
+  "collaborative" checkbox. The mental model stays "this is a bucket", the
+  plugin only layers sync on top.
+- **Polling, not push.** No long-lived connection, no WebSocket, no daemon.
+  30-second cadence is perfectly fine for the "someone added a card to our
+  shared bucket" latency envelope and reuses the existing relay HTTP path.
+- **Relay as source of truth.** The local mirror is almost stateless — only
+  `last_seen_at` is user-specific and never leaves the device. Wipes and
+  re-syncs are trivial.
+- **Owner-only writes.** Simpler than ACLs. Owners who want to hand off
+  control can delete-and-recreate, or we add a transfer endpoint in Phase 4.
+- **Soft coupling to core.** Core exposes two tiny hooks
+  (`window._collabBucketsCreateDialog`, `window.state`) plus a single
+  column on the buckets table. Everything else — dialog, decoration,
+  polling, mark-seen — lives in the plugin directory and goes away when
+  the plugin is disabled.
+
+## Disabling
+

+# collab-buckets plugin — roadmap
+
+> Phase 1, 2 and 3 are shipped: metadata + membership sync, bucket-bar
+> integration, and full card sync with encrypted round-trip and LWW
+> conflict resolution. Phase 4 is polish — edit locks, ownership
+> transfer, member presence, etc. Phase 5 is hardening.
+
+## Phase 3 — card sync (DONE ✓)
+
+- [x] **`collab_card_state` table (local)** — maps a local `cards.id` to
+      a collab `bucket_uid` + `relay_uid` plus `last_push_at` and
+      `last_remote_at` for LWW tracking. Poll phase 1 finds dirty cards
+      via `c.updated_at > cs.last_push_at`.
+- [x] **Save propagation without editor coupling** — the poll's push
+      phase is query-based (no trigger, no hook). Whenever the user
+      saves a card and the core bumps `cards.updated_at`, the next
+      poll within 30s finds it dirty and pushes.
+- [x] **Relay `collab_cards` table + routes** — `POST /api/collab-cards`
+      decrypts-reencrypts via inter-tenant key; `GET ?since=<ts>`
+      re-encrypts per recipient; `DELETE /{bucket}/{card}` marks a
+      tombstone with a 7-day TTL (cleaned up by bootstrap.php).
+- [x] **Poll extension** — `collabSyncCards()` runs three phases
+      (tombstones → push → pull) with a temp-table suppress flag so the
+      delete trigger doesn't re-enqueue during apply.
+- [x] **Card visibility** — collab buckets already take part in the core
+      bucket-bar's click-to-filter flow, so cards synced into them
+      automatically show up on the board.
+- [x] **Card deletion propagation** — BEFORE DELETE trigger writes to
+      `collab_tombstones`. Drained in the next poll as a DELETE.
+      Suppressed during the apply phase so remote deletes don't loop
+      back as local tombstones.
+- [x] **Conflict losers as "(conflict from X)" duplicates** — when the
+      apply phase is about to LWW-clobber a local card that had edits
+      since our last push (`local.updated_at > collab_card_state.last_push_at`),
+      we now INSERT a copy of the local version into a local-only
+      "Conflicts" bucket with a `(conflict from <author>) ...` title
+      prefix before the overwrite. The poll response carries a
+      `conflicts` count; the frontend pops a toast pointing the user at
+      the Conflicts bucket when it's non-zero.
+- [x] **Moving a card between collab buckets (or out to a local one)**
+      — the push phase now has a pre-pass that finds cards where
+      `collab_card_state.bucket_uid` no longer matches the card's
+      current bucket collab_uid. For each such card it sends a
+      tombstone to the old bucket. If the card is still in a (different)
+      collab bucket, state is rewritten with the new `bucket_uid` and
+      `last_push_at = NULL` so the main push loop re-uploads under the
+      new bucket. If the card left collab entirely, the state row is
+      removed.
+
+## Phase 4 — polish
+
+- [x] **Per-card edit lock** — when the editor opens on a collab card the
+      plugin heartbeats `POST /api/collab-locks {bucket_uid, card_uid}`
+      every 30 s with a 60 s TTL on the relay. The lock list is folded
+      into the regular `/api/collab-buckets/poll` response so no extra
+      round-trips are needed. Foreign locks show a 🔒 badge on the
+      affected board card + a subtle inset outline. Releases on editor
+      close and best-effort on `beforeunload` via `fetch(..., keepalive)`.
+      Advisory only — users can still force-edit; LWW + conflict stashing
+      remain the final arbiter. Core `editor.js` dispatches
+      `hyprcrd:editor-open` / `hyprcrd:editor-close` `CustomEvent`s so
+      the plugin hooks in without monkey-patching.
+- [x] **Ownership transfer** — `PATCH /api/collab-buckets/{uid}`
+      accepts `{owner: <username>}`. The relay validates that the new
+      owner is currently a member, swaps `owner_id` + `owner_username`,
+      and forces both the caller and the new owner to stay in the member
+      list on the same request. Surfaced in the UI via a new "Members &
+      owner…" entry in the bucket context menu that opens a plugin
+      dialog with a member picker + owner dropdown (only shown when the
+      caller is the current owner; other members see a read-only view).
+- [ ] **Position propagation (optional)** — reorder is purely local right
+      now. If multiple members expect the same order, we'd need to sync
+      `position` via the relay, but it's probably fine to leave this as a
+      per-user preference.
+- [ ] **Member presence indicator** — show a small dot next to usernames in
+      the members panel when they were seen by the relay within the last
+      minute (reuse chat's heartbeat or add a collab-specific ping).
+- [ ] **"Recently active members"** — show avatars (first letter) of
+      members who touched a card in the last hour, on the collab bucket tab.
+- [ ] **Read receipts** — "3 / 5 seen" for the latest update on each
+      collab bucket. Requires the relay to store per-member `last_seen_at`
+      — bigger schema change.
+
+## Phase 5 — hardening & UX
+
+- [x] **Migration of existing local buckets** — the bucket context menu
+      on a non-collab bucket shows a "Make collaborative…" entry when
+      the plugin is loaded. It opens a plugin dialog where the owner
+      picks members, then `POST /api/collab-buckets/upgrade
+      {bucket_id, members}` generates a new `uid`, pushes it to the
+      relay, and writes `collab_uid` onto the same local `buckets` row
+      — no card shuffling, no id rewrite. The first poll after the
+      upgrade sees every card in the bucket as dirty (no
+      `collab_card_state`) and pushes them.
+- [x] **Undo for destructive actions** — local bucket delete/leave now
+      hooks into the existing `pushUndo` system: the undo entry
+      recreates the bucket via `POST /api/buckets`, restores the
+      original color+position with PATCH, and re-attaches every card
+      that pointed at the old row. Collab bucket delete/leave is
+      intentionally *not* wired — restoring would need to recreate on
+      the relay under a new uid and re-attach cards there too, which
+      is messy and less valuable since collab deletes are usually
+      deliberate.
+- [x] **Resilient create via outbox** — a new
+      `collab_bucket_outbox(id, bucket_id, members_json, queued_at)`
+      table. The create/upgrade flow always creates the local `buckets`
+      row first and then tries `collabAttemptUpgrade()`. On relay
+      failure the intent is queued in the outbox and the next poll
+      retries. The response includes `queued: true` so the frontend can
+      show a "saved locally, will sync later" info toast; a follow-up
+      poll that successfully drains the outbox fires a second toast.
+      Stale outbox entries for deleted buckets are dropped automatically.
+- [x] **Rate limiting on collab endpoints** — every collab route now
+      funnels through the existing relay `isRateLimited()` helper with
+      generous caps (120/min for GET, 240/min for POST). Over-limit
+      requests get a clean `429 rate limited` response.
+- [ ] **Inline member picker in the bucket context menu** — currently
+      needs the manage-modal for any change. A quick `+user` / `-user`
+      flyout would help for tiny edits.
+- [ ] **Owner-side member approval flow** — owners can still add any
+      relay user unilaterally. A pending-invite state with accept/reject
+      on the invitee side would be nicer for consent but requires a new
+      relay table + plumbing.
+
+## Known limitations (current)
+
+- **LWW conflicts still clobber on the remote side.** When two users save
+  the same card within a few seconds, the later writer wins. The earlier
+  writer gets their local version stashed into a `Conflicts` bucket and
+  a toast notification — nothing is lost — but their version is no
+  longer the canonical one anyone else sees. Phase 4 edit-locks prevent
+  the race in the first place.
+- **Up to ~30 s sync latency.** Changes propagate on the next poll, not
+  instantly. Acceptable for MVP; a "push now" hook after save would cut
+  latency to ~1 s.
+- **Full resync on every poll.** Cheap for small member counts but grows
+  O(N_buckets × N_members) on the relay side. A `since=updated_at` filter
+  would help — adding it is safe because the poll also has to handle full
+  removals (kicked from bucket), and we can fold the deletion list into the
+  response.
+- **Bucket metadata is plaintext on the relay.** Name + color + member list
+  are visible to a relay admin with DB access. Card content (Phase 3) will
+  be encrypted end-to-end via the existing decrypt-reencrypt hop; bucket
+  metadata could follow the same pattern but adds complexity for minimal
+  gain and makes member picking harder.
+- **No offline support.** Creating a bucket while the relay is unreachable
+  fails hard. Phase 5 outbox pattern would fix this.
+- **Race on UID generation.** The client generates `bin2hex(random_bytes(8))`
+  = 64 bits of entropy. Collisions between independent clients are
+  astronomically unlikely, but the relay rejects them with 409 if they ever
+  happen. No retry on the client side yet.

+// rows in the standard bucket bar. The plugin just owns the sync + the
+// visual unread-state decoration:
+//
+//  - Polls /api/collab-buckets/poll every POLL_INTERVAL_MS. The backend
+//    mirrors each remote bucket into the main `buckets` table so the core
+//    bucket bar renders it automatically.
+//  - Exposes `window._collabBucketsCreateDialog` — an async function that
+//    the core + Bucket button calls so we can pop a richer "new bucket"
+//    modal with an optional "collaborative" checkbox + member picker.
+//  - Watches #bucket-bar via MutationObserver. After every render, finds
+//    tabs whose data-bucket id corresponds to a collab bucket and attaches
+//    a pulse animation + red unread dot if the bucket has unread state.
+//  - Delegated click handler on #bucket-bar calls mark-seen for collab tabs.
+//
+// The plugin never touches the header anymore. No more standalone tiles.

+# email plugin — deferred features
+
+> **Note:** Account management lives in the main settings overlay under
+> "mail" (added via `hyprcrd.settings.registerTab`). The email overlay
+> shows a welcome screen with a "configure accounts" button when no
+> accounts are set up — that button switches to the settings tab.
+
+
+
+This is the MVP scope. The following are intentionally not implemented yet
+and can be added later as plugin-only changes (no core touch needed):
+
+## Protocol
+
+- [ ] **SMTP / sending** — currently read-only. Add SmtpClient.php + a
+      compose view in the overlay. Reuse account credentials (most providers
+      use the same login for IMAP + SMTP, just different host/port).
+- [ ] **STARTTLS on port 143** — only direct SSL on 993 works today. Need to
+      send `STLS` command after the greeting and wrap the socket via
+      `stream_socket_enable_crypto`.
+- [ ] **IDLE / push** — currently each `loadMessages()` is a fresh poll. IDLE
+      would let the server notify on new mail. Tricky with PHP request model;
+      probably needs a small daemon or long-poll endpoint.
+- [ ] **OAuth2 (XOAUTH2)** — Gmail/O365 require OAuth instead of app
+      passwords for full functionality. Big chunk of work: token exchange,
+      refresh, storage.
+
+## Folders & search
+
+- [ ] **Multiple folders** — schema has `folder` column but UI exposes only
+      one. Add folder list pane (like Thunderbird's left sidebar) using
+      `LIST "" *`.
+- [ ] **Server-side search** — `UID SEARCH FROM "..."`, `SUBJECT "..."`,
+      `SINCE date`, etc. Currently the UI shows the latest 30 only.
+- [ ] **Threading** — group messages by `In-Reply-To` / `References` headers.
+- [ ] **Mark as read / unread** — `UID STORE +FLAGS (\Seen)`.
+- [ ] **Move to folder** — `UID COPY <folder>` + delete from current.
+- [x] **Delete on server** — implemented: multi-select checkboxes in list pane,
+      "delete" button in selection bar, calls `UID STORE +FLAGS (\Deleted)`
+      + `EXPUNGE` (see `ImapClient::deleteUids()`).
+
+## Body & attachments
+
+- [x] **HTML email rendering** — implemented: opt-in "view as html" button per
+      message renders the HTML in a sandboxed iframe (srcdoc + DOMPurify).
+      External images are blocked by default; "load images (N)" button reveals
+      them on demand. CSS background-image url() declarations are also stripped
+      from inline styles. cid: refs aren't loaded (would need a separate route).
+- [ ] **Inline images** — `cid:` references inside HTML need to fetch
+      `multipart/related` parts and serve them via a data: URL.
+- [ ] **Attachments list + download** — parse `Content-Disposition: attachment`
+      parts, expose them in the message header bar, route through a backend
+      endpoint that streams the decoded part to the browser.
+
+## UI / UX
+
+- [ ] **Pagination** — currently hard limit of 30 newest messages.
+- [ ] **Per-account folder + signature settings** — extend the form.
+- [ ] **Notification on new mail** — needs IDLE or polling daemon.
+- [ ] **Drag-extract** — drag a message onto the board to create a card at
+      that position.
+- [ ] **Reply / forward** — needs SMTP first.
+- [ ] **Address book / autocomplete** — pull historic sender addresses.
+
+## Spam detection (current state)
+
+- [x] **Multi-signal heuristic scorer** (`SpamDetector.php`):
+      header signals (X-Spam-*, SPF/DKIM/DMARC), subject heuristics
+      (CAPS, punctuation, EN+DE keyword phrases, Cyrillic homoglyphs),
+      sender heuristics (suspicious TLDs, digit-heavy domains, Reply-To
+      mismatch, display-name impersonation), bulk-mail signal.
+      Three levels: clean / suspicious / spam.
+- [x] **Visual marking** in message list: red row + badge for spam,
+      yellow row + badge for suspicious. Hover tooltip shows reasons.
+- [ ] **Body-content scoring** — `SpamDetector::score()` already accepts
+      a body parameter; wire it up in the message-open route to refine
+      the score with link density / short URL detection. Currently the
+      list view scores headers only.
+- [x] **User feedback loop** — implemented: `email_spam_rules` table holds
+      block/allow rules per sender email or domain. UI has "select spam"
+      bulk-select button + "spam" / "not spam" buttons in the selection bar.
+      Free email providers (gmail, gmx, etc.) get email-only rules to avoid
+      blocking entire providers; other domains get domain-level rules.
+      Block adds +15, allow subtracts -15 in `SpamDetector`.
+- [ ] **Bayesian classifier** — collect tokens from user-marked spam vs
+      ham; train a per-account model. SQLite-backed, no external deps.
+- [ ] **Spam rules management UI** — currently rules are write-only via
+      mark buttons. A list view in settings would let users see and remove
+      stale rules.
+
+## Hardening
+
+- [ ] **Rate limiting** on the test endpoint to prevent credential brute force.
+- [ ] **Better error messages** — currently raw IMAP server errors leak
+      through. Should map common ones (auth failed, connection refused,
+      cert error) to friendly text.
+- [ ] **Cert pinning option** for users on self-hosted mail servers.
+- [ ] **Connection reuse** — every API call opens + closes IMAP. A short
+      session cache (per account, 30s) would be much faster.
+
+## Why these were deferred
+
+The scope of "build an email plugin" is essentially "build a mail client",
+which is a multi-month project on its own. The MVP proves the plugin system
+can host a non-trivial feature with a backend, schema, encrypted
+credentials, custom API routes, and a complex UI — all without touching
+the hyprcrd core. Each item above can be added as an isolated patch to this
+plugin directory, and the plugin can still be disabled in settings to fully
+remove the feature.

+# gitea plugin — roadmap
+
+> **Status:** scaffold. Phase 1 = accounts CRUD + connection test only.
+> The `gitea-issue-client/` Python tool in the project root is the
+> reference for the full feature surface that needs to be ported.
+
+## Phase 1 — done ✅
+
+- [x] `GiteaClient.php` cURL wrapper with `testConnection()`,
+      `searchIssues()`, `listRepoIssues()`, `getIssue()`, `listIssueComments()`
+- [x] `gitea_accounts` table with encrypted token (vault key, same as email)
+- [x] Routes: `GET/POST/PATCH/DELETE /api/gitea/accounts` + `POST .../test`
+- [x] Settings tab via `hyprcrd.settings.registerTab`
+- [x] Header button "gitea"
+- [x] Welcome view + accounts management form
+- [x] Connection test against `/api/v1/user`
+
+## Phase 2 — issue reader ✅
+
+- [x] **Issue list view** in the overlay:
+      - Search box (`q` parameter, debounced 350ms)
+      - State filter (open/closed/all)
+      - Pagination (prev/next, hasMore heuristic since Gitea doesn't always return total)
+      - Each row: title, repo path, state badge, labels, author, age
+- [x] **Issue detail view** (right pane):
+      - Subject + state badge + labels + #number + repo
+      - Body (markdown rendered via `hyprcrd.markdown.render` — exposed by core)
+      - Comments list (each with author + relative timestamp + rendered markdown)
+      - "Open on Gitea" link button
+- [x] **Extract → card**:
+      - Card title = `[repo#number] title`
+      - Card body = metadata header + body + comments + `#gitea #issue` tags
+      - Color: green (#22c55e)
+- [ ] **Issue → card backlink** in a `gitea_issue_links` table — needed
+      for Phase 5 bidirectional sync
+
+## Phase 3 — write operations
+
+- [x] **Add comment** — composer textarea always visible at the bottom of the
+      detail pane. Ctrl/Cmd+Enter posts. New comment is appended to local state
+      and re-rendered immediately.
+- [x] **Close / reopen** — single button in the action bar that toggles state.
+      Updates the badge, button label, and the row in the list.
+- [x] **Edit title** — pencil icon next to the title swaps to an inline input.
+      Enter saves, Escape cancels. PATCH `/issues/{index}`.
+- [x] **Edit body** — pencil icon next to the body swaps to a textarea.
+      Ctrl/Cmd+Enter saves, Escape cancels.
+- [x] **Set labels** — tag icon opens an inline editor that fetches the repo's
+      label list (`GET /api/gitea/repo/.../labels`) and shows checkboxes with
+      original colors. Save uses `PUT /issues/{index}/labels`.
+- [ ] **Set assignees** — needs a collaborator typeahead (next round, see
+      TODO Phase 3.5)
+- [ ] **Set milestone** — needs milestone fetch + dropdown (next round)
+- [ ] **Set due date** — date picker (next round)
+
+## Phase 3.5 — remaining metadata
+
+- [x] `GET /api/gitea/repo/{accId}/{owner}/{repo}/milestones` (added with create form)
+- [x] `GET /api/gitea/repo/{accId}/{owner}/{repo}/collaborators` (added with create form)
+- [x] Milestone dropdown — currently in **create** form only
+- [x] Assignee multi-select — currently in **create** form only
+- [x] Same metadata editors in the **detail** view: combined inline editor
+      that lets you change assignees, milestone, and due date all at once.
+      Single PATCH call handles all three. Re-fetches the issue after save
+      to keep state in sync.
+- [x] Due date input + clear button (create skipped due_date but edit has it)
+- [ ] Due date in the **create** form too (currently only on edit)
+- [ ] **Project assignment** — gitea's API does NOT include `project` in
+      `CreateIssueOption` or `EditIssueOption`. Issues are added to projects
+      via separate board endpoints which differ across gitea versions. Punt
+      until there's a clear API surface to target.
+
+## Phase 4 — create issues
+
+- [x] **"new issue" button** in the list toolbar
+- [x] **Repo picker** loaded from `/user/repos` (cached per account, filtered
+      to non-archived repos with push permission)
+- [x] **Title + body + labels** form
+- [x] **Submit** creates via POST `/repo/{accId}/{owner}/{repo}/issues`,
+      refreshes list, auto-opens the new issue in the detail view
+- [ ] **Create from card**: a card → push as new gitea issue, store the
+      backref so future edits can sync both ways (Phase 5)
+- [ ] **Pre-fill template** from a repo's `.gitea/ISSUE_TEMPLATE.md`
+      if available (next round)
+
+## Phase 5 — bidirectional sync (the killer feature)
+
+- [ ] When a card has a gitea backref, an "issue" badge appears
+- [ ] Edit the card body in hyprcrd → "push to gitea" button
+- [ ] "pull from gitea" button refreshes the card from the live issue
+- [ ] Conflict detection via `updated_at` timestamps
+- [ ] This replaces the Python tool's `gir push` workflow
+
+## Phase 6 — multi-instance + ergonomics
+
+- [ ] Account selector remembers last-used account in localStorage
+- [ ] Per-account default filters (e.g. always show `assigned=true`)
+- [ ] Org/repo browsing tree on the left
+- [ ] Label browser per repo
+- [ ] Milestone view
+- [ ] Search across multiple accounts
+
+## Hardening
+
+- [ ] Rate limiting on test endpoint
+- [ ] Better error messages (currently raw HTTP body leaks through)
+- [ ] Cert pinning option for self-hosted gitea instances
+- [ ] Connection caching (currently every request opens a new cURL handle)
+- [ ] Map common errors (401 → "token expired", 403 → "no access", etc.)
+
+## Mapping from the Python tool

+|----------------------------------------|-------------------------------------------|
+| `gi search`                             | overlay issue list with `q` filter        |
+| `gi list --owner --repo`                | overlay with owner/repo filter            |
+| `gi get`                                | overlay detail pane                       |
+| `gi create`                             | Phase 4 "new issue" button                |
+| `gi edit`                               | Phase 3 detail-pane edit buttons          |
+| `gi comment`                            | Phase 3 comment box in detail pane        |
+| `gi comments`                           | Phase 2 comments rendering                |
+| `gir fetch` → markdown files            | Phase 2 extract-as-card (no files needed) |
+| `gir push` → sync local edits           | Phase 5 bidirectional sync                |
+| `gir new --push`                        | Phase 4 create-from-card                  |
+| `gir clean`                             | not needed (cards are managed via the UI) |
+| `_valid-metadata.md` per repo           | label/milestone dropdowns at edit time    |
+| `templates/gir-new-issue.md`            | configurable issue template per account   |
+
+Once Phase 2–4 are done, the entire `gitea-issue-client/` Python tool
+can be removed from the project root.
