+# Phase 7 — Composer Redesign (Hybrid)
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Reduce composer toolbar from 9 cluttered icons to 5 hierarchically-organized buttons. Move "creative activities" (Whiteboard, Watch-Together, Mini-Games) into a `+` popover. Move View-Once from global composer toggle to per-attachment flag in the upload preview.
+
+**Rollback anchor:** tag `pre-phase7-composer` (set in T1).
+
+---
+
+## Task 1: Rollback anchor
+
+- [ ] Run:
+```bash
+cd "D:\Programmieren\ChatApp-Electron\chat-app"
+git tag -a pre-phase7-composer -m "Rollback anchor before Phase 7 composer redesign"
+```
+
+---
+
+## Task 2: `<ComposerActionsMenu>` popover component
+
+**Files:** Create `apps/desktop/src/components/ComposerActionsMenu.tsx`
+
+**Shape:**
+
+```tsx
+interface Props {
+  anchorRef: React.RefObject<HTMLButtonElement | null>;
+  open: boolean;
+  onClose: () => void;
+  onAttachFile: () => void;
+  onCreatePoll: () => void;
+  onCreateWhiteboard: () => void;
+  onStartWatchTogether: () => void;
+  onStartGame: () => void;
+  canStartGame?: boolean;
+}
+```
+
+Layout (floating panel anchored above `anchorRef`):
+
+```
+┌─────────────────────────────┐
+│ 📎  Bild / Datei            │
+│ 📊  Umfrage                 │
+├─────────────────────────────┤
+│   AKTIVITÄTEN               │
+│ ✏  Whiteboard               │
+│ 📺  Watch Together          │
+│ 🎮  Spiel starten           │
+└─────────────────────────────┘
+```
+
+- Use existing icons from `apps/desktop/src/components/icons.tsx` (grep for `PaperclipIcon`/`PlusIcon`, `PollIcon`, `MonitorShareIcon`, `PlayBoxIcon`, `GameIcon`).
+- Click outside or `Esc` → `onClose`.
+- Disabled items: `opacity-50 cursor-not-allowed` + `title` hint (e.g. "Spiele nur in 1:1-Chats").
+- Each row ≥ 44px tall, `role="menu"`/`role="menuitem"`, arrow-up/down keyboard nav.
+
+---
+
+## Task 3: Refactor ConversationPage composer
+
+**Files:** Modify `apps/desktop/src/pages/ConversationPage.tsx`
+
+**Target layout:**
+
+```
+┌────────────────────────────────────────────────────────┐
+│ [+]  [😊]  [GIF]  [🎤]   Nachricht schreiben…    [→] │
+└────────────────────────────────────────────────────────┘
+```
+
+Changes:
+1. **Remove** inline buttons for: file-attach, poll, whiteboard, watch-together, game-picker.
+2. **Add** a `+` button at position 1 with a `useRef` anchor.
+3. **State:** `const [menuOpen, setMenuOpen] = useState(false);` + render `<ComposerActionsMenu>` with the existing handlers wired (`handleCreateWhiteboard`, `handleStartWatchTogether`, `handleStartGame`, `() => setPollDialogOpen(true)`, `() => fileInputRef.current?.click()`).
+4. **Remove** the standalone View-Once toggle button (moves to T4 per-attachment).
+5. **Keep inline:** Emoji picker, GIF picker, voice mic, send arrow.
+6. **Auto-close menu** after any item action.
+7. Pass `canStartGame={conversation?.members?.length === 2}` so the dropdown reflects the DM-only constraint.
+
+---
+
+## Task 4: View-Once per-attachment in `AttachmentPreview`
+
+**Files:**
+- Modify `apps/desktop/src/pages/ConversationPage.tsx` (`AttachmentPreview` component + the `attachments[]` state shape).
+- Modify `apps/desktop/src/hooks/useConversationMessages.ts` (`send()` signature + per-attachment handling).
+- Possibly extend the per-attachment encrypt/upload helper if it still treats `viewOnce` as a per-message flag.
+
+**Behavior:**
+
+Add a third hover-button on each image preview next to `✏` and `✕`: a `👁` icon that toggles `viewOnce` per attachment.
+- Active: icon switches (e.g. crossed-eye) + small `1×` badge in lower-right corner of the thumb.
+- Image-only (`file.type.startsWith('image/')`). Hidden on non-image previews.
+
+**State refactor:**
+
+Change `attachments: File[]` → `attachments: Array<{ file: File; viewOnce: boolean }>`. Every consumer site updated:
+- `setAttachments((prev) => [...prev, ...newOnes.map((f) => ({ file: f, viewOnce: false }))])`
+- `attachments.map((a, idx) => <AttachmentPreview file={a.file} ... onToggleViewOnce={() => setAttachments(prev => prev.map((x, i) => i === idx ? { ...x, viewOnce: !x.viewOnce } : x))} />)`
+- `setAttachments((prev) => prev.filter((_, i) => i !== idx))` — unchanged shape
+
+**Send path:**
+
+The `send()` currently accepts a `viewOnce` option that applies globally. Refactor so the per-attachment flag flows through:
+- Either change `send(payload, attachments, replyTo, { viewOnce })` → `send(payload, attachmentsWithFlags, replyTo)` where each entry carries its own `viewOnce`
+- OR pass a parallel `viewOnceFlags: boolean[]` array aligned with attachments
+
+The encrypt/upload helper already supports per-attachment `view_once` (P2.T14 column `message_attachments.view_once`). The renderer just needs to pass the right flag per row.
+
+**Grep first** to find the existing wiring: `Grep -rn "view_once\|viewOnce" apps/desktop/src/ packages/shared/src/chat/` — adapt to what's actually there.
+
+---
+
+## Task 5: Cleanup + Final gate
+
+- [ ] `pnpm --filter @chat-app/desktop typecheck` — green
+- [ ] `pnpm --filter @chat-app/shared test -- --run` — green (71 tests)
+- [ ] `pnpm --filter @chat-app/desktop test -- --run` — green
+- [ ] `git status` — clean
+- [ ] Tag `phase7-done`
+- [ ] Report smoke-test points:
+  1. Composer shows 5 inline buttons (was 9)
+  2. Click `+` → popover opens; click anywhere outside or `Esc` closes it
+  3. Attach image → preview shows ✏/👁/✕ on hover
+  4. Toggle 👁 on attachment-1 only → recipient sees attachment-1 as view-once, attachment-2 normally
+  5. Everything else unchanged (emoji, GIF, voice, send, edit-message, etc.)
+
+---
+
+## Non-goals
+
+- No emoji-as-icon (uses existing SVG icons).
+- No slash-commands (deferred to potential Phase 7B).
+- No reordering of inline buttons beyond the spec.
+- No per-attachment poll-attach (polls remain message-level).
