+# 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/`           |
+| Windows  | NSIS     | `dist/`           |
+| Linux    | AppImage | `dist/`           |
+
+## File structure
+
+```
+electron/
+  main.js          Electron main process — spawns PHP, creates window
+  preload.js       Exposes window.hyprcrdElectron (platform, isElectron)
+  router.php       PHP built-in server router (replaces .htaccess)
+  fetch-php.sh     Downloads static PHP binaries for all platforms
+  php-bin/         Platform-specific PHP binaries (gitignored)

+# 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.

+| `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 |

+
+### 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. |
+
+## Schema (local)

+    updated_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    last_seen_at TEXT                    -- NULL = never opened → unread
+);
+
+-- 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
+-- relay; the push phase picks up cards where c.updated_at > last_push_at.
+-- `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,
+    FOREIGN KEY (owner_id) REFERENCES tenants(id) ON DELETE CASCADE
+);
+CREATE TABLE collab_bucket_members (
+    bucket_uid TEXT NOT NULL,
+    tenant_id INTEGER NOT NULL,
+    username TEXT NOT NULL,
+    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
+
+Like every other plugin, add `"collab-buckets"` to the `disabled` array in
+`data/plugins.json`. The local table is left in place (not dropped) so
+re-enabling doesn't lose unread state.

+# 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.

+ * Collab Buckets Plugin: backend.
+ *
+ * Local mirror of the relay's collab_buckets state. Provides a thin proxy

+ * does a full resync (so deletions / removed memberships propagate).
+ *
+ * Routes:
+ *   GET    /api/collab-buckets              list local buckets
+ *   POST   /api/collab-buckets              {name, color, members[]} -> create on relay + mirror local
+ *   PATCH  /api/collab-buckets/{uid}        {name?, color?, members?} -> push to relay
+ *   DELETE /api/collab-buckets/{uid}        owner: delete; member: leave
+ *   POST   /api/collab-buckets/poll         full re-sync from relay
+ *   POST   /api/collab-buckets/mark-seen    {uid} -> reset dot/pulse state
+ *   GET    /api/collab-buckets/relay-tenants proxy to relay /api/tenants for the member-picker
+ *
+ * Phase 1+2: bucket metadata + membership only. Card sync lands in Phase 3.

+// Phase 1+2 shape (post-refactor): collab buckets are first-class bucket
+// 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.
