+## P. Accessibility (P3-4) — needs a browser + a screen reader
+
+The compliance fixes are gate-verified in code; these confirm the runtime a11y behavior only a human + AT can check. Tools: browser DevTools "axe" extension / Lighthouse a11y, plus **VoiceOver** (macOS ⌘F5) or **NVDA** (Windows).
+
+### P1. Keyboard-only golden path (no mouse)
+
+Tab from page load: **skip-to-content** link appears first (Enter jumps to the timeline). Tab reaches the room list (rooms are focusable, active room announced), open a room (Enter), type a character → focus lands in the composer, send with Enter (or Shift+Enter per your `enterForNewline` setting). No keyboard trap; visible focus ring throughout.
+
+### P2. `?` shortcuts dialog
+
+Press **?** (Shift+/) with focus NOT in a text field → the keyboard-shortcuts dialog opens, is focus-trapped, Escape closes it and focus returns to where you were. Pressing `?` while typing in the composer/search inserts a literal `?` (does NOT open the dialog).
+
+### P3. Screen-reader: reading messages
+
+With VoiceOver/NVDA on, arrow through the timeline: each message is announced as an article with **sender name + time** — critically, this includes **collapsed messages** (consecutive messages from the same person), which previously announced only the body with no sender. Reactions, "edited", replies, and delivery status are announced with labels.
+
+### P4. Screen-reader: live announcements
+
+- **New message** arrives while you're reading → announced (polite).
+- **Someone starts typing** → "X is typing" announced once (not spammed per keystroke).
+- **Editing a message** → the edit box announces "Editing message from X".
+
+### P5. Focus return from dialogs
+
+Open then close (Escape or ×): the **room topic viewer**, a **reaction viewer** (click a reaction count), and **Search** → focus returns to the button/element you opened them from (not lost to `<body>`). Inline popouts (emoji picker, autocomplete, hover menus) intentionally keep focus in context — that's expected, not a bug.
+
+### P6. axe / Lighthouse scan
+
+Run the axe DevTools extension (or Lighthouse → Accessibility) on a room view, Settings, and the login screen. Expect **no critical/serious** "missing accessible name" or "ARIA" violations on the golden path. Report any that appear (note: far-scrolled timeline history being virtualized out is a known, accepted limitation — not a finding).

 ## Priority if you're short on time

 1. **O1 + O2** (threads + per-thread notifications) — the largest new surface; the main-timeline change is user-visible.
