+# Story 1.4: Core Logic — ScryingPoolController & VisibilityManager *(Headless)*
+
+## Status: done
+
+## Story
+
+As a **developer**,
+I want the module's core orchestration logic to be independently tested without any UI,
+So that the GM control UI (Story 1.5) can be built against a stable, verified interface.
+
+## Acceptance Criteria
+
+**AC-1 — ScryingPoolController construction:**
+**Given** `Hooks.once('ready')` fires
+**When** `ScryingPoolController` is constructed as the module singleton
+**Then** it owns `visibilityMatrix: Map<string, PendingOp>` (`pendingOps`) and state tracking
+**And** it is wired to subscribe to socket echo events (via `init()`)
+
+**AC-2 — action() happy path:**
+**Given** `ScryingPoolController.action(source, participantId, targetState, opId, baseRevision)` is called by a GM
+**When** the call is processed
+**Then** a `PendingOp` is created in the controller's `_pendingOps` map
+**And** `StateStore.setVisibility(participantId, targetState)` is called (optimistic)
+**And** `SocketHandler.emit(event, payload)` is called with the intent message
+**And** `SocketHandler.registerPendingOp(pendingOp)` is called
+**And** `Hooks.callAll('scrying-pool:controllerAction', { participantId, targetState, source, opId })` fires for UI subscribers
+
+**AC-3 — latest-revision-wins guard:**
+**Given** `action()` is called with a `baseRevision` lower than the stored `_currentRevision` for that participant
+**When** the call is processed
+**Then** the action is silently dropped (no state change, no emit, no warning)
+
+**AC-4 — per-participant last-intent guard:**
+**Given** `action()` is called for a participant whose current state ALREADY equals `targetState`
+**When** the call is processed
+**Then** the action is silently dropped (idempotent — prevents redundant socket traffic)
+
+**AC-5 — non-GM authorization:**
+**Given** `action()` is called when `adapter.users.isGM()` returns false
+**When** the call is processed
+**Then** `console.warn('[ScryingPool]', ...)` is logged and the call is silently dropped
+**And** no state mutation, no socket emit, no PendingOp registered
+
+**AC-6 — VisibilityManager webrtcMode strategy (track-disable):**
+**Given** `adapter.settings.get('webrtcMode')` returns `'track-disable'`
+**When** `StateStore` emits `scrying-pool:stateChanged` with `state: 'hidden'`
+**Then** `VisibilityManager` calls `adapter.webrtc.disableTrack(participantId)`
+**When** `StateStore` emits `scrying-pool:stateChanged` with `state: 'active'`
+**Then** `VisibilityManager` calls `adapter.webrtc.enableTrack(participantId)`
+
+**AC-7 — VisibilityManager webrtcMode strategy (css-fallback / unsupported):**
+**Given** `adapter.settings.get('webrtcMode')` returns `'css-fallback'` or `'unsupported'`
+**When** `StateStore` emits `scrying-pool:stateChanged`
+**Then** `VisibilityManager` performs NO webrtc call (CSS is applied by `RoleRenderer` in Story 1.5)
+**And** NO error is thrown even if `adapter.webrtc` is null
+
+**AC-8 — SocketHandler.setReady wiring:**
+**Given** the `ready` hook fires
+**When** `VisibilityManager` is constructed
+**Then** `socketHandler.setReady(visibilityManager)` is called immediately after
+**And** the socket message queue is drained
+
+**AC-9 — revert path:**
+**Given** `SocketHandler` calls `visibilityManager.onRevert(pendingOp)` (after retry exhaustion)
+**When** `onRevert` is processed
+**Then** `StateStore.setVisibility(pendingOp.userId, pendingOp.previousState)` is called (revert to previousState)
+**And** `adapter.notifications.warn('[ScryingPool] ...')` fires with a human-readable message
+**And** NO success notification fires for normal (non-revert) state changes
+
+**AC-10 — null webrtc safe:**
+**Given** `adapter.webrtc` is null (css-fallback path — the current spike result for v14)
+**When** any state change fires
+**Then** no error is thrown — the absence of `adapter.webrtc` is handled gracefully in both tracks
+
+**AC-11 — echo reconciliation:**
+**Given** a socket echo is received on `'scrying-pool.visibility.updated'`
+**When** `ScryingPoolController._onEcho(payload)` processes it
+**Then** `socketHandler.confirmPendingOp(opId)` is called (clears timer)
+**And** `StateStore.setVisibility(userId, state)` is called with the authoritative state
+**And** `Hooks.callAll('scrying-pool:controllerAction', { participantId: userId, targetState: state, source: 'echo', opId })` fires
+
+**AC-12 — unit test coverage:**
+**Given** the test suite
+**Then** `ScryingPoolController` tests cover: normal action, latest-revision-wins, last-intent guard, non-GM rejection, echo reconciliation
+**And** `VisibilityManager` tests cover: track-disable strategy, css-fallback no-op, null webrtc guard, onRevert (revert + notification), no success notification
+**And** all tests use `createFoundryAdapterMock()` from `tests/helpers/foundryAdapterMock.js` — no ad-hoc stubs

+## Dev Notes
+
+### Architecture
+
+**Naming clarification (architecture vs epics):** The architecture doc uses `VisibilityManager` generically for the entire core logic layer. Story 1.4 splits this into two separate classes with clear separation of concerns:
+
+- `ScryingPoolController` — **state orchestration**: authorizes actions, manages `_pendingOps`, fires change events, handles socket echo reconciliation. This is the layer UI (Strip, Board) calls.
+- `VisibilityManager` — **strategy applier + SocketHandler handler**: applies the `webrtcMode` strategy (webrtc API or CSS signal), implements `onRevert(pendingOp)` for SocketHandler timeout callbacks.
+
+The architecture's `VisibilityManager.toggle()` dataflow maps to `ScryingPoolController.action()` in this story.
+
+**Init order (EXACT — do not deviate):**
+```
+Hooks.once('ready')
+  → stateStore.init()                              // already done in Story 1.3
+  → FoundryAdapter.probeCapability() + set webrtcMode   // already done in Story 1.3
+  → visibilityManager = new VisibilityManager(stateStore, adapter)
+  → visibilityManager.init()                       // registers Hooks.on('scrying-pool:stateChanged')
+  → socketHandler.setReady(visibilityManager)      // drains queue; visibilityManager is the onRevert handler
+  → scryingPoolController = new ScryingPoolController(stateStore, socketHandler, adapter)
+  → scryingPoolController.init()                   // registers socket.on('scrying-pool.visibility.updated')
+  // Story 1.5+: NotificationBus → RoleRenderer → RosterStrip → DirectorsBoard (lazy)
+```
+
+**Why VisibilityManager before ScryingPoolController:**
+`socketHandler.setReady(visibilityManager)` must be called before `scryingPoolController.init()` registers the echo listener, otherwise early echoes could arrive before the handler is registered. VisibilityManager must be ready to handle `onRevert` before any ops can time out.
+
+**Dependency injection hard rule** (from architecture):
+`ScryingPoolController` and `VisibilityManager` MUST have ZERO direct `game.*` access. All Foundry dependencies come through the injected `adapter`. This is enforced by ESLint import boundaries.
+
+**Import rule for `src/core/`:** `src/core/` may only import from `src/contracts/` and `src/utils/`. No imports from `src/foundry/`, `src/ui/`, `src/notifications/`, or `src/presets/`.
+
+### ScryingPoolController Details
+
+**State owned by ScryingPoolController:**
+```js
+this._pendingOps = new Map();      // participantId → PendingOp
+this._revisions  = new Map();      // participantId → last-confirmed baseRevision
+```
+
+**action() algorithm:**
+```js
+action(source, participantId, targetState, opId, baseRevision) {
+  // 1. Authorization
+  if (!this._adapter.users.isGM()) {
+    console.warn('[ScryingPool] ScryingPoolController.action: non-GM call rejected');
+    return;
+  }
+  // 2. Latest-revision-wins guard
+  const currentRevision = this._revisions.get(participantId) ?? 0;
+  if (baseRevision < currentRevision) return; // stale — silently drop
+  // 3. Last-intent guard
+  const currentState = this._stateStore.getState(participantId);
+  if (currentState === targetState) return;   // already in target state — no-op
+  // 4. Register PendingOp
+  const previousState = currentState ?? 'never-connected';
+  const pendingOp = createPendingOp(opId, participantId, targetState, previousState);
+  this._pendingOps.set(participantId, pendingOp);
+  // 5. Optimistic state update
+  this._stateStore.setVisibility(participantId, targetState);
+  // 6. Socket emit
+  const msg = createSocketIntentMessage(opId, participantId, targetState, baseRevision);
+  this._socketHandler.emit(msg.event, msg.payload);
+  // 7. Register PendingOp in SocketHandler (starts timeout)
+  this._socketHandler.registerPendingOp(pendingOp, msg.event, msg.payload);
+  // 8. Notify UI
+  Hooks.callAll('scrying-pool:controllerAction', { participantId, targetState, source, opId });
+}
+```
+
+**_onEcho(payload) algorithm:**
+```js
+_onEcho(payload) {
+  const { opId, userId, state, revision } = payload;
+  this._socketHandler.confirmPendingOp(opId);          // clears timer
+  this._revisions.set(userId, revision ?? 0);          // update revision
+  this._pendingOps.delete(userId);                     // clear controller tracking
+  this._stateStore.setVisibility(userId, state);       // authoritative update
+  Hooks.callAll('scrying-pool:controllerAction', {
+    participantId: userId, targetState: state, source: 'echo', opId
+  });
+}
+```
+
+**Note on `baseRevision`:** `_revisions` tracks the confirmed revision from echo. `action()` compares `baseRevision` (caller's view) against `_revisions.get(participantId)`. If the echo's `revision` is always incremented by StateStore (it is — `_revision++` on every `setVisibility`), the guard prevents stale late-arriving actions from overwriting fresh echoes.
+
+### VisibilityManager Details
+
+**constructor(stateStore, adapter):** Side-effect free — no Hooks.on calls.
+
+**init():** Registers:
+```js
+Hooks.on('scrying-pool:stateChanged', (data) => this._onStateChanged(data));
+```
+
+**_onStateChanged({ userId, state }) algorithm:**
+```js
+_onStateChanged({ userId, state }) {
+  const mode = this._adapter.settings.get('webrtcMode');
+  if (mode !== 'track-disable' || !this._adapter.webrtc) return;
+  if (state === 'hidden') {
+    this._adapter.webrtc.disableTrack(userId);
+  } else {
+    this._adapter.webrtc.enableTrack(userId);
+  }
+}
+```
+
+**onRevert(pendingOp) algorithm:**
+```js
+onRevert(pendingOp) {
+  this._stateStore.setVisibility(pendingOp.userId, pendingOp.previousState);
+  this._adapter.notifications.warn(
+    `[ScryingPool] Visibility change for ${pendingOp.userId} could not be confirmed — reverting to ${pendingOp.previousState}`
+  );
+}
+```
+
+**Key: no success notification.** `onRevert` calls `notifications.warn`. Normal state changes (action → echo) MUST NOT call `notifications.*`.
+
+### Hooks used in this story
+
+| Hook | Direction | Who calls | Who listens |
+|------|-----------|-----------|-------------|
+| `scrying-pool:stateChanged` | Hooks.callAll | StateStore | VisibilityManager, (Story 1.5: RoleRenderer) |
+| `scrying-pool:controllerAction` | Hooks.callAll | ScryingPoolController | (Story 1.5: ScryingPoolStrip, DirectorsBoard) |
+
+`Hooks.callAll` is a standalone FoundryVTT global (same as in StateStore — no import needed, safe in `src/core/`).
+
+### Existing Files Being Modified
+
+**`module.js`** current ready hook (Story 1.3 state):
+```js
+Hooks.once("ready", () => {
+  stateStore.init();
+  const outcome = FoundryAdapter.probeCapability(game.webrtc);
+  adapter.webrtc = outcome === 'track-disable' ? FoundryAdapter.buildWebRTCSurface(game.webrtc) : null;
+  adapter.settings.set(FoundryAdapter.SETTING_WEBRTC_MODE, outcome).catch(...);
+  // Story 1.4: construct VisibilityManager and call socketHandler.setReady(visibilityManager)
+});
+```
+
+Replace the comment with the actual wiring (see Task 3). The `webrtcMode` setting is already set before VisibilityManager is constructed — VisibilityManager reads it dynamically via `adapter.settings.get('webrtcMode')` on each state change, so the order is fine.
+
+### Contract Files Used
+
+| File | Usage |
+|------|-------|
+| `src/contracts/pending-op.js` | `createPendingOp()` in ScryingPoolController.action() |
+| `src/contracts/socket-message.js` | `createSocketIntentMessage()`, `SOCKET_EVENTS` in ScryingPoolController |
+| `src/contracts/visibility-matrix.js` | `VISIBILITY_STATES` for guard validation (optional) |
+| `src/utils/uuid.js` | `generateOpId()` — but opId is PASSED IN by the caller (Story 1.5's UI), not generated here |
+
+**Note on opId:** In Story 1.4, `action(source, participantId, targetState, opId, baseRevision)` receives opId from the caller. `generateOpId()` will be called in Story 1.5 by the UI layer (RosterStrip) when constructing the call. Tests in Story 1.4 can use hardcoded opId strings like `'op-test-1'`.
+
+### Test Patterns
+
+**Canonical mock — always use this:**
+```js
+import { createFoundryAdapterMock } from '../../helpers/foundryAdapterMock.js';
+const adapter = createFoundryAdapterMock();
+// Override webrtc for track-disable tests:
+const adapterWithWebrtc = createFoundryAdapterMock({
+  webrtc: { disableTrack: vi.fn(), enableTrack: vi.fn() },
+  users: { isGM: () => true, get: () => null, all: () => [], current: () => null },
+});
+```
+
+**Override isGM for authorization tests:**
+```js
+const gmAdapter = createFoundryAdapterMock({ users: { isGM: () => true } });
+const playerAdapter = createFoundryAdapterMock({ users: { isGM: () => false } });
+```
+
+**Stub Hooks global for controllerAction assertions:**
+```js
+import { vi } from 'vitest';
+// In beforeEach:
+vi.stubGlobal('Hooks', { callAll: vi.fn(), on: vi.fn(), once: vi.fn(), off: vi.fn() });
+// In afterEach:
+vi.unstubAllGlobals();
+```
+
+**Fake timers (if testing timeout paths in integration):**
+```js
+vi.useFakeTimers();
+vi.advanceTimersByTime(3001);
+vi.useRealTimers();
+```
+Note: SocketHandler's timeout logic is already tested in Story 1.3's SocketHandler.test.js. Story 1.4 does NOT need to re-test SocketHandler internals — mock it instead.
+
+**SocketHandler mock for ScryingPoolController tests:**
+```js
+function makeSocketHandler() {
+  return {
+    emit: vi.fn(),
+    registerPendingOp: vi.fn(),
+    confirmPendingOp: vi.fn(),
+    setReady: vi.fn(),
+  };
+}
+```
+
+### ESLint / TypeScript Notes (Learnings from Story 1.3)
+
+- Add JSDoc class comment (`/** ... */`) above EVERY exported class — `jsdoc/require-jsdoc` rule
+- Use `// eslint-disable-next-line no-unused-vars` (line comment, not block comment) on the line ABOVE a `catch (_)` binding
+- `Hooks.callAll(event, data)` — TypeScript expects `(...args: unknown[]) => void` for any passed handler
+- The `Hooks` global is `declare const Hooks` in `src/types/foundry-globals.d.ts` — do NOT add a new declaration, it already exists
+- `ui` global is `declare const ui` — also already in `foundry-globals.d.ts` (added in Story 1.3) with `notifications.info/warn/error` methods
+
+### OQ-1 Spike Result (Story 1.2)
+
+`adapter.webrtc` is ALWAYS `null` in production (v14 CSS fallback path). The `track-disable` branch in VisibilityManager is dead code in the current environment. Test it anyway (it's the future-proof path), but the `null` guard MUST be correct — if `adapter.webrtc` is null, `_onStateChanged` must be a pure no-op with no errors.
+
+### Project Structure Notes
+
+**Files to create:**
+```
+src/core/ScryingPoolController.js          ← NEW (Story 1.4)
+src/core/VisibilityManager.js              ← NEW (Story 1.4)
+tests/unit/core/ScryingPoolController.test.js  ← NEW (Story 1.4)
+tests/unit/core/VisibilityManager.test.js      ← NEW (Story 1.4)
+```
+
+**Files to update:**
+```
+module.js                                  ← UPDATE: ready hook wiring
+```
+
+**Files NOT changed in this story:**
+- `src/contracts/` — all contracts already exist and are correct
+- `tests/fixtures/` — existing fixtures are sufficient; do NOT add VisibilityManager-specific fixtures (use inline objects in tests)
+- `src/foundry/FoundryAdapter.js` — no changes needed
+- CSS files — Story 1.4 is headless (no DOM/CSS)
+
+**Import boundary (enforced by ESLint):**
+```
+src/core/ScryingPoolController.js  → only: src/contracts/, src/utils/
+src/core/VisibilityManager.js      → only: src/contracts/, src/utils/
+```

+## Review Findings
+
+### Patch
+
+- [x] [Review][Patch] Hooks not injected through adapter — Both ScryingPoolController and VisibilityManager use global `Hooks` directly instead of `adapter.hooks.callAll()` and `adapter.hooks.on()`. Violates architecture rule "All Foundry dependencies come through injected adapter." [ScryingPoolController.js:88,103 VisibilityManager.js:33]
+- [x] [Review][Patch] Memory leak in _pendingOps Map — SocketHandler timeout deletes pending ops from its own map but ScryingPoolController._pendingOps retains entries forever if echo never arrives. [ScryingPoolController.js:28,67]
+- [x] [Review][Patch] module.js init lacks error handling — If visibilityManager.init(), socketHandler.setReady(), or scryingPoolController.init() throws, the ready hook fails silently leaving module in broken state. [module.js:85-92]
+- [x] [Review][Patch] Missing input validation in action() — No validation for participantId, targetState, opId, baseRevision parameters; invalid inputs cause downstream errors. [ScryingPoolController.js:50-75]
+- [x] [Review][Patch] Missing payload validation in _onEcho() — No checks that payload contains required opId, userId, state fields; missing fields cause silent failures. [ScryingPoolController.js:93-107]
+
+### Defer
+
+- [x] [Review][Defer] Memory leak in _revisions Map — No cleanup of old/disconnected userIds from _revisions Map; grows unbounded over time. [ScryingPoolController.js:31] — deferred, pre-existing pattern
+- [x] [Review][Defer] No listener cleanup — Socket and Hooks listeners registered in init() are never unregistered; potential memory leak on module reload. [ScryingPoolController.js:35-41, VisibilityManager.js:33-38] — deferred, needs architecture decision on destroy pattern
+
+### Dismiss
+
+- [x] [Review][Dismiss] Import rule violation in JSDoc — JSDoc type references to StateStore in constructor params are type-only annotations, not runtime imports; actual imports are from contracts only. — dismissed, false positive
+- [x] [Review][Dismiss] AC-1 "Missing visibilityMatrix Map" — Spec states `visibilityMatrix: Map<string, PendingOp> (pendingOps)`; code correctly implements `_pendingOps` per the parenthetical clarification. — dismissed, spec naming inconsistency
+- [x] [Review][Dismiss] Only 2 of 8 states handled — Spec's canonical algorithm explicitly uses else branch treating all non-'hidden' as 'active'; matches implementation. — dismissed, matches spec intent
+- [x] [Review][Dismiss] Race condition between action() and _onEcho() — Latest-revision-wins and last-intent guards handle concurrent actions by design. — dismissed, handled by guards

+## Dev Agent Record
+
+### Agent Model Used
+
+Claude Sonnet 4.6 (claude-sonnet-4.6)
+
+### Debug Log References
+
+- No blockers encountered. All 4 tasks completed in sequence without halts.
+- ESLint: removed unused disable comment on `scryingPoolController` (ESLint doesn't flag module-level lets as unused). Removed `/** JSDoc block */` from `getEchoHandler()` test helper (replaced with `//` line comment to avoid jsdoc/require-returns warning).
+- lint exits with 7 pre-existing errors in `scripts/package.mjs` (not Story 1.4 scope). No new errors introduced.
+
+### Completion Notes List
+
+- ✅ Task 1: `ScryingPoolController.js` — 22 TDD tests written first (red), then implementation (green). All ACs 1–5 and 11 covered. Constructor side-effect free; `init()` registers echo listener; `action()` has 3 guards (isGM, revision, idempotent); `_onEcho()` reconciles authoritative state.
+- ✅ Task 2: `VisibilityManager.js` — 13 TDD tests written first (red), then implementation (green). All ACs 6, 7, 9, 10 covered. Constructor side-effect free; `init()` registers stateChanged hook; `_onStateChanged()` applies strategy with null webrtc guard; `onRevert()` reverts + warns, no success notification.
+- ✅ Task 3: `module.js` ready hook — exact init order: VisibilityManager.init() → socketHandler.setReady(visibilityManager) → ScryingPoolController.init(). Placeholder comment removed. Both new imports added.
+- ✅ Task 4: Pipeline — lint clean (no new errors), typecheck clean, **181 tests passing** (target ≥175).

+# Story 1.5: GM Control UI — ScryingPoolStrip, ActionPopover & AV Tile Integration
+
+Status: done
+
+## Story
+
+As a **GM**,
+I want to right-click any participant's AV tile to show or hide their camera feed, and see all feed states at a glance in the ScryingPoolStrip,
+So that I can control what the table sees in a single interaction without disrupting the session.
+
+## Acceptance Criteria
+
+**AC-1 — ScryingPoolStrip appears on ready:**
+**Given** the module is active and the user is GM
+**When** FoundryVTT's `ready` hook completes
+**Then** `ScryingPoolStrip` appears as a floating `ApplicationV2` window showing all connected participants
+**And** its position (`left`, `top`), open state, and expanded state persist to the GM's user flag `{ left, top, open, expanded }`
+
+**AC-2 — Collapsed/expanded toggle:**
+**Given** the ScryingPoolStrip is in collapsed state
+**When** the GM clicks the expand toggle
+**Then** the strip transitions via `max-width` CSS transition (never `width` animation): collapsed = 44px avatar-only rail; expanded = 240px rich rows
+
+**AC-3 — ParticipantAvatar rendering:**
+**Given** the strip renders participants
+**When** it displays each `ParticipantAvatar`
+**Then** each avatar is a 44×44px container with a 32px rounded avatar + `StateRing` + 12px corner badge at bottom-right
+**And** `StateRing` uses the correct variant per state: `--solid` (active/self-muted), `--dashed` (hidden/cam-lost), `--pending` (animated pulse), `--revert` (amber flash 200ms on revert)
+**And** all `StateRing` animations are gated under `@media (prefers-reduced-motion: no-preference)`
+
+**AC-4 — Pending op ring:**
+**Given** a PendingOp is in-flight for a participant
+**When** the strip renders
+**Then** that participant's `StateRing` shows the `--pending` animated pulse
+**And** NO `ui.notifications` toast fires on successful state change (success uses ambient ring only — tier-1/2 feedback)
+
+**AC-5 — Right-click context menu:**
+**Given** a GM right-clicks a participant's avatar in the ScryingPoolStrip
+**When** the context menu appears
+**Then** the option reads exactly **"Hide from table"** (never a synonym)
+**And** selecting it calls `ScryingPoolController.action()` and transitions state to `hidden`
+
+**AC-6 — ActionPopover on click:**
+**Given** a GM clicks a participant in the ScryingPoolStrip
+**When** the `ActionPopover` opens
+**Then** it is a native `<dialog>` anchored via `StripOverlayLayer.getBoundingClientRect()` relative to the strip
+**And** the primary CTA reads exactly **"Hide from table"** or **"Show to table"**
+**And** the primary CTA is `disabled` + `aria-disabled="true"` while a `PendingOp` is in-flight
+**And** Esc / click-outside dismiss the popover and return focus to the triggering avatar
+**And** only one `ActionPopover` is open at a time (supersede pattern)
+
+**AC-7 — StripOverlayLayer overlay container:**
+**Given** `StripOverlayLayer` is the parent for all positioned overlays
+**When** any overlay is positioned
+**Then** it is a child of the single `StripOverlayLayer` (`position: absolute; inset: 0; pointer-events: none; overflow: visible`); children restore `pointer-events: auto`
+
+**AC-8 — AV tile state indicators:**
+**Given** a visibility change is dispatched
+**When** the socket broadcast completes
+**Then** all clients' AV tiles update state indicators within 500ms
+**And** no AV tile layout shift or reflow occurs for any of the 8 participant states
+**And** `AVTileAdapter.mount(userId, element)` is idempotent — calling it twice does not duplicate elements
+
+**AC-9 — Hidden state on GM tile view:**
+**Given** a participant is `hidden`
+**When** the GM views their AV tile
+**Then** it renders at reduced opacity with a lock overlay and "Camera hidden by GM" tooltip
+**And** the GM still hears that participant's audio
+
+**AC-10 — Portrait Fallback:**
+**Given** a participant has no camera (`never-connected` or `cam-lost`)
+**When** their tile renders
+**Then** Portrait Fallback (FoundryVTT user avatar → system placeholder) displays at AV tile dimensions with no layout shift
+
+**AC-11 — EmptyStatePanel:**
+**Given** no participants are connected
+**When** the ScryingPoolStrip renders
+**Then** `EmptyStatePanel` shows "No participants yet" with a slow breathing-pulse eye icon (static under `prefers-reduced-motion`)
+**And** the panel is NOT styled as an error state
+
+**AC-12 — GM self-feed setting:**
+**Given** the GM opens module settings
+**When** they locate "Show my own feed to myself" (default ON)
+**Then** toggling it hides/shows the GM's self-view immediately without errors
+
+**AC-13 — Null webrtc guard:**
+**Given** `game.webrtc` is null (AV disabled)
+**When** the module loads
+**Then** `ScryingPoolStrip` is not rendered and no console errors appear
+
+**Accessibility:**
+
+**AC-14 — ParticipantAvatar accessibility:**
+**Given** a screen reader user navigates to a `ParticipantAvatar`
+**When** focus lands
+**Then** `role="button"`, `aria-label="[Name] — [state label]"` is announced
+**And** `aria-pressed` reflects popover-open state
+
+**AC-15 — ActionPopover keyboard navigation:**
+**Given** a keyboard user opens an `ActionPopover`
+**When** it opens
+**Then** focus moves to the primary CTA
+**And** Tab/Shift+Tab cycles through popover controls only
+**And** Esc closes it and returns focus to the triggering avatar
+
+**AC-16 — Reduced motion:**
+**Given** `prefers-reduced-motion: reduce` is active
+**When** any animated state occurs
+**Then** all `StateRing` animations are fully suppressed; static icons provide state information
+
+**AC-17 — Second-signal rule:**
+**Given** any participant state is rendered
+**When** it is visually displayed
+**Then** colour is never the only signal: each state also has a distinct icon, shape, or motion indicator
+**And** all state colour tokens meet WCAG AA contrast against both Foundry dark and light themes
+
+**AC-18 — Canonical action label:**
+**Given** a canonical action label appears on any surface
+**When** it is displayed
+**Then** it reads exactly "Hide from table" or "Show to table" (never synonyms)
+**And** on first hover a tooltip variant sets `firstHideTooltip` flag; subsequent hovers show only the canonical label
+

+  - [x] 1.1: Write failing tests in `tests/unit/ui/shared/AVTileAdapter.test.js` first (TDD red)
+  - [x] 1.2: Implement `constructor(adapter)` — side-effect free; stores adapter reference; no DOM access in constructor
+  - [x] 1.3: Implement `mount(userId, element)` — idempotent: query tile by `[data-user-id="${userId}"]`; append element with `data-sp-mount` attribute; no-op + `console.warn('[ScryingPool]', ...)` if tile not found (fail-open); no duplicate if element already present
+  - [x] 1.4: Implement `unmount(userId)` — remove all `[data-sp-mount]` children from tile; no-op if tile not found
+  - [x] 1.5: Implement `setStateClass(userId, stateName)` — remove all `sp-state-*` classes from tile; add `sp-state-${stateName}` (no-op if tile not found, with console.warn)
+  - [x] 1.6: Implement `onTileRerender(userId, callback)` — attach scoped `MutationObserver` (`childList: true, subtree: false`) to the tile element; call `callback(tileElement)` when DOM changes detected; store observer by userId for cleanup; no-op if tile not found
+  - [x] 1.7: Implement `disconnect()` — disconnect all stored MutationObservers; clear internal observer map; safe to call multiple times
+  - [x] 1.8: Confirm tests green, run full suite (no regressions)
+
+- [x] Task 2: Create `src/ui/RoleRenderer.js` (AC: 8, 9, 10, 12, 13)
+  - [x] 2.1: Write failing tests in `tests/unit/ui/RoleRenderer.test.js` first (TDD red)
+  - [x] 2.2: Implement `constructor(stateStore, scryingPoolController, avTileAdapter, adapter)` — side-effect free; store all injected deps; no Hooks registration in constructor
+  - [x] 2.3: Implement `init()` — register `Hooks.on('scrying-pool:stateChanged', ...)` to call `_applyAVTileState(userId, state)`; register `Hooks.on('scrying-pool:controllerAction', ...)` to call `_onControllerAction(data)` for pending ring updates; register `Hooks.on('updateUser', ...)` for mid-session role-change rebuilds
+  - [x] 2.4: Implement `_applyAVTileState(userId, state)` — resolve state precedence (see architecture precedence table), call `avTileAdapter.setStateClass(userId, resolvedState)`, mount/unmount lock overlay for `hidden`, mount/unmount portrait fallback for `never-connected`/`cam-lost`
+  - [x] 2.5: Implement `_onControllerAction({ participantId, targetState, source })` — for `pending` ops in-flight: add `sp-state-pending` class via `avTileAdapter.setStateClass(participantId, 'pending')`; on echo/confirmation, restore actual state
+  - [x] 2.6: Implement null webrtc guard: check `adapter.users.isGM()` and `game.webrtc` (via adapter); if AV disabled, do NOT construct ScryingPoolStrip; log `console.log('[ScryingPool] AV disabled — ScryingPoolStrip not rendered')`
+  - [x] 2.7: Implement `openStrip()` / `closeStrip()` — construct `ScryingPoolStrip` singleton lazily; open/close it (GM only)
+  - [x] 2.8: Confirm tests green, run full suite (no regressions)
+
+- [x] Task 3: Create `src/ui/gm/ScryingPoolStrip.js` + update `templates/roster-strip.hbs` (AC: 1, 2, 3, 4, 5, 6, 7, 11, 13, 14, 15, 16, 17, 18)
+  - [x] 3.1: Write failing tests in `tests/unit/ui/gm/ScryingPoolStrip.test.js` (TDD red — test logic, not ApplicationV2 rendering)
+  - [x] 3.2: Implement `ScryingPoolStrip extends Application` (using `Application` class for simpler FoundryVTT v14 compatibility; reference Architecture §Initialisation Order; see Dev Notes for ApplicationV2 vs Application guidance)
+  - [x] 3.3: Implement `static get defaultOptions()` — set `id: 'scrying-pool-strip'`, `template: 'modules/video-view-manager/templates/roster-strip.hbs'`, `popOut: true`, `resizable: false`, `title: 'Scrying Pool'`
+  - [x] 3.4: Implement `getData()` — build participant list from `stateStore`; return `{ participants, isExpanded, isEmpty }` — see Dev Notes for participant data shape
+  - [x] 3.5: Implement `activateListeners(html)` — bind click on `.sp-participant-avatar` → `_openPopover(participantId, el)`, right-click → `_openContextMenu(participantId, el)`, expand toggle → `_toggleExpanded()`
+  - [x] 3.6: Implement position persistence — on `close`: save `{ left, top, open: false, expanded }` to `game.user.setFlag('video-view-manager', 'stripState', {...})`; on `render`: restore from flag or use default position
+  - [x] 3.7: Implement `_toggleExpanded()` — toggle `.is-expanded` class on strip element; save `expanded` to user flag
+  - [x] 3.8: Implement `_openPopover(participantId, anchorEl)` — supersede existing popover (call `close('superseded')` on `this._activePopover`), create new `ActionPopover`, anchor via `getBoundingClientRect()` relative to strip, store ref in `this._activePopover`
+  - [x] 3.9: Implement `_openContextMenu(participantId, anchorEl)` — build Foundry-style context menu with single entry: `{ name: 'Hide from table', icon: 'fas fa-eye-slash', callback: () => this._dispatchAction(participantId) }`; use canonical label constant (see Dev Notes)
+  - [x] 3.10: Implement `_dispatchAction(participantId)` — determine target state (current=active → hidden; else → active); call `scryingPoolController.action('strip', participantId, targetState, generateOpId(), this._getRevision(participantId))`
+  - [x] 3.11: Update `templates/roster-strip.hbs` with actual ScryingPoolStrip template markup — see Dev Notes §Template Structure
+  - [x] 3.12: Implement `firstStripOpen` tip — on first open (flag unset): show right-click affordance tip in strip header; set `game.user.setFlag('video-view-manager', 'firstStripOpen', true)`; never show again
+  - [x] 3.13: Confirm tests green, run full suite (no regressions)
+
+- [x] Task 4: Implement `ActionPopover` class inside `src/ui/gm/ScryingPoolStrip.js` (AC: 6, 15)
+  - [x] 4.1: Implement `ActionPopover` class (not exported; internal to the gm/ layer; or extract to `src/ui/gm/ActionPopover.js` if file grows unwieldy — dev agent's call)
+  - [x] 4.2: Implement `constructor(participantId, currentState, anchorRect, stripElement, onAction)` — build `<dialog>` element with `h3` name + state label, primary CTA button (`data-action="primary-cta"`), aria attributes
+  - [x] 4.3: Implement `open(anchorEl)` — call `dialog.showModal()`; position via `anchorRect.getBoundingClientRect()` relative to strip; focus primary CTA; attach click-outside listener (click on backdrop area dismisses)
+  - [x] 4.4: Implement `close(reason)` — call `dialog.close(reason)`; remove click-outside listener; return focus to triggering avatar
+  - [x] 4.5: Implement disabled state during PendingOp — primary CTA gets `disabled` + `aria-disabled="true"` attribute when `ScryingPoolController` has a pending op for this participant; listen to `scrying-pool:controllerAction` hook to update
+  - [x] 4.6: Wire Esc via native `<dialog>` cancel event → call `close()`; return focus to trigger
+
+- [x] Task 5: Add CSS — LESS styles for all new components (AC: 2, 3, 4, 16, 17)
+  - [x] 5.1: Add `StateRing` CSS variants to `styles/components/_roster-strip.less` (or extract to `styles/components/_state-ring.less` and `@import` it): `.sp-state-ring--solid`, `--dashed`, `--pending`, `--revert` — see Dev Notes §StateRing CSS spec
+  - [x] 5.2: Add `ParticipantAvatar` layout CSS: 44×44px container, 32px rounded avatar, 12px corner badge bottom-right; hover action rail (fixed-width, reveal via `opacity/visibility/pointer-events`, never `display:none`)
+  - [x] 5.3: Add ScryingPoolStrip layout CSS: floating window, collapsed/expanded states using `max-width` transition (never `width`), `.is-expanded` modifier
+  - [x] 5.4: Add AV tile overlay styles in `styles/components/_roster-strip.less` (scoped to `.scrying-pool` for strip, on `:root` for AV tile tokens): `sp-state-hidden` → reduced opacity + lock-overlay icon; portrait fallback sizing (AV tile dimensions, no layout shift)
+  - [x] 5.5: Add `EmptyStatePanel` CSS: breathing-pulse eye icon (gated under `prefers-reduced-motion: no-preference`), centred layout, NOT styled as error
+  - [x] 5.6: Run `npm run build` — exits 0
+
+- [x] Task 6: Update `module.js` — wire RoleRenderer and ScryingPoolStrip into ready hook (AC: 1, 12, 13)
+  - [x] 6.1: Add imports: `import { RoleRenderer } from './src/ui/RoleRenderer.js';` + `import { AVTileAdapter } from './src/ui/shared/AVTileAdapter.js';`
+  - [x] 6.2: Add module-level `let roleRenderer; let avTileAdapter;`
+  - [x] 6.3: In `Hooks.once('ready')`: after `scryingPoolController.init()`, construct `avTileAdapter = new AVTileAdapter(adapter)` then `roleRenderer = new RoleRenderer(stateStore, scryingPoolController, avTileAdapter, adapter)` then `roleRenderer.init()`
+  - [x] 6.4: If `adapter.users.isGM()`, call `roleRenderer.openStrip()` to render ScryingPoolStrip
+  - [x] 6.5: Update init order comment in module.js: remove `// Story 1.5: NotificationBus → RoleRenderer → RosterStrip` placeholder; document actual current order; add `// Story 2.1: NotificationBus` placeholder for next story
+  - [x] 6.6: Run full pipeline — lint + typecheck + test (all must pass)
+
+- [x] Task 7: Pipeline validation (AC: all)
+  - [x] 7.1: `npm run lint` — exits 0 (no new errors beyond the 7 pre-existing in scripts/package.mjs)
+  - [x] 7.2: `npm run typecheck` — exits 0
+  - [x] 7.3: `npm run test` — all tests pass (≥181 baseline + ~40 new = ≥221 expected)
+  - [x] 7.4: `npm run build` — exits 0 (LESS compiles cleanly)

+
+### Review Findings
+
+#### Decision Needed
+*(None)
+
+#### Patch Required
+- [x] [Review][Patch] Race condition: non-atomic pending op check [ScryingPoolController.js:119] — `hasPendingOp()` check is non-atomic; concurrent calls can bypass guard, creating multiple pending ops for same participant — **Fixed: Added atomic check before registering pending op**
+- [x] [Review][Patch] Echo doesn't verify pending op exists [ScryingPoolController.js:164] — Confirms any opId without checking `_pendingOps.has()` or opId match; can confirm stale/nonexistent ops — **Fixed: Verify pending op exists and opId matches before confirming**
+- [x] [Review][Patch] Pending op key mismatch [ScryingPoolController.js:123,167] — `action()` stores by `participantId`, `_onEcho` deletes by `userId`; if mismatch, pending op leaks and never cleaned up — **Fixed: Consistent use of userId/participantId; verify opId matches**
+- [x] [Review][Patch] Future revisions silently allowed [ScryingPoolController.js:119] — Latest-revision-wins guard only rejects `baseRevision < currentRevision`; allows `baseRevision > currentRevision` which may overwrite newer state — **Fixed: Changed to strict equality check (`!==`)**
+- [x] [Review][Patch] No targetState validation [ScryingPoolController.js:117] — Accepts any string for `targetState`; optimistic update and socket emit happen before StateStore rejection — **Fixed: Validate against VISIBILITY_STATES**
+- [x] [Review][Patch] Memory leak: unbounded maps [ScryingPoolController.js:28-30] — `_pendingOps` and `_revisions` maps have no cleanup on participant disconnect; grow unbounded over time — **Fixed: Added cleanupParticipant() and cleanupAll() methods; cleanupPendingOp now also cleans revisions**
+- [x] [Review][Patch] Uncaught stateStore exceptions [ScryingPoolController.js:117-121] — `getState()` and `setVisibility()` calls not wrapped in try-catch; pending op registered but state may be inconsistent if they throw — **Fixed: Wrapped in try-catch blocks**
+- [x] [Review][Patch] Concurrent actions overwrite pending op [ScryingPoolController.js:123] — If `action()` called twice for same participantId before first echo, second overwrites first's PendingOp; first echo fails to find its op — **Fixed: Check for existing pending op before overwriting**
+- [x] [Review][Patch] Binary state assumption [VisibilityManager.js:59-63] — Only checks `state === 'hidden'` to disable track; other states ('offline', 'cam-lost', 'ghost') incorrectly treated as enableTrack — **Fixed: Handle all hidden-like states**
+- [x] [Review][Patch] No webrtc method validation [VisibilityManager.js:61-63] — Checks `mode !== 'track-disable' || !webrtc` but assumes webrtc has `disableTrack`/`enableTrack` if non-null — **Fixed: Validate methods exist before calling**
+- [x] [Review][Patch] Mode type validation missing [VisibilityManager.js:53] — `mode !== 'track-disable'` compares against potentially non-string value from settings.get() — **Fixed: Validate mode is string before comparison**
+
+#### Deferred
+- [x] [Review][Defer] Echo accepts non-finite revisions [ScryingPoolController.js:164] — No validation that `revision` is finite; accepts `NaN`, `Infinity` — deferred, pre-existing
+- [x] [Review][Defer] No validation revision is number [ScryingPoolController.js:164] — `revision ?? 0` doesn't validate `revision` is a number type — deferred, pre-existing
+
+## Dev Notes
+
+### Architecture Context
+
+This story builds the first UI layer of the module. All previous stories (1.1–1.4) were headless infrastructure. Story 1.5 introduces:
+1. `AVTileAdapter` — isolates all Foundry AV tile DOM interactions
+2. `RoleRenderer` — reactive dispatcher subscribing to state change hooks; applies CSS to AV tiles; constructs GM UI
+3. `ScryingPoolStrip` — ApplicationV2-style floating window (the GM's primary control surface)
+4. `ActionPopover` — native `<dialog>` for per-participant hide/show actions
+
+**Naming clarification (architecture doc vs story):**
+The architecture doc calls the L1 GM strip `RosterStrip.js` (in `src/ui/gm/`). This story uses `ScryingPoolStrip` (which appears in all UX spec and epics references). Use `ScryingPoolStrip` as both the class name and filename: `src/ui/gm/ScryingPoolStrip.js`. The architecture file-level name is just an approximation — story spec takes precedence.
+
+**RoleRenderer vs VisibilityManager:**
+`VisibilityManager` (Story 1.4) applies WebRTC track logic (hidden → disableTrack). `RoleRenderer` (Story 1.5) applies CSS/DOM visual state to AV tiles — different concern. Do NOT conflate them.
+
+**ScryingPoolController is the source of truth for actions:**
+`ScryingPoolStrip` is a dumb view. It NEVER calls `stateStore.setState()` directly. All mutations go through `ScryingPoolController.action(source, participantId, targetState, opId, baseRevision)`. The strip reads state from `stateStore.getState(userId)`.
+
+### Init Order (EXACT — do not deviate)
+
+```
+Hooks.once('ready')
+  → stateStore.init()                              // Story 1.3
+  → FoundryAdapter.probeCapability() + webrtcMode  // Story 1.3
+  → visibilityManager = new VisibilityManager(...)  // Story 1.4
+  → visibilityManager.init()                        // Story 1.4
+  → socketHandler.setReady(...)                     // Story 1.4
+  → scryingPoolController = new ScryingPoolController(...)  // Story 1.4
+  → scryingPoolController.init()                    // Story 1.4
+  → avTileAdapter = new AVTileAdapter(adapter)      // Story 1.5 (NEW)
+  → roleRenderer = new RoleRenderer(stateStore, scryingPoolController, avTileAdapter, adapter)  // Story 1.5 (NEW)
+  → roleRenderer.init()                             // Story 1.5 (NEW)
+  → if isGM: roleRenderer.openStrip()              // Story 1.5 (NEW)
+  // Story 2.1: NotificationBus
+  // Story 2.2: DirectorsBoard (lazy, GM only)
+```
+
+**Why AVTileAdapter before RoleRenderer:** `RoleRenderer` receives `avTileAdapter` via constructor injection. It needs the adapter ready before `init()` wires hooks that call through to it.
+
+### Import Boundaries (HARD — enforced by ESLint)
+
+```
+src/ui/              → may import: src/core/, src/contracts/, src/utils/
+src/ui/gm/           → may import: src/core/, src/contracts/, src/utils/, src/ui/shared/
+src/ui/shared/       → may import: src/contracts/, src/utils/
+```
+
+❌ `src/ui/` importing `src/foundry/` is a hard violation (FoundryAdapter comes in via constructor injection).
+❌ `src/core/` importing `src/ui/` is a hard violation.
+
+### Dependency Injection — Zero Direct game.* Access
+
+`RoleRenderer`, `AVTileAdapter`, and `ScryingPoolStrip` MUST have zero direct `game.*` access for testability. All Foundry API dependencies come through the injected `adapter`.
+
+**Exception for AVTileAdapter:** DOM access via `document.querySelector()` is permissible — it cannot be avoided for AV tile DOM manipulation. Wrap in try/catch; never throw on missing tile. `happy-dom` (Vitest environment) provides `document` in tests.
+
+**Exception for ScryingPoolStrip:** `Application` / `ApplicationV2` extend from Foundry's global. In tests, mock at the class level (see §Test Patterns below). Business logic that can be extracted into pure functions should be.
+
+### Canonical Label Constants
+
+Create a constants object at the top of `ScryingPoolStrip.js`:
+```js
+const LABELS = Object.freeze({
+  HIDE_FROM_TABLE: 'Hide from table',
+  SHOW_TO_TABLE:   'Show to table',
+  FIRST_TOOLTIP:   'Hide this participant from other players.',
+});
+```
+All surfaces MUST reference these constants — never inline string literals for action labels.
+
+### Participant Data Shape (for getData())
+
+```js
+// Shape returned by ScryingPoolStrip.getData()
+{
+  participants: [
+    {
+      userId: 'user-abc',
+      name: 'Alice',         // from adapter.users.get(userId).name
+      avatarSrc: '...',      // from adapter.users.get(userId).avatar
+      state: 'active',       // from stateStore.getState(userId)
+      stateLabel: 'Active',  // human-readable label (not player vocabulary partition — GM sees state names)
+      hasPendingOp: false,   // check scryingPoolController._pendingOps.has(userId)
+      isCurrentUser: false,  // adapter.users.current()?.id === userId
+    }
+  ],
+  isExpanded: true,          // from user flag or default true on firstStripOpen
+  isEmpty: false,
+}
+```
+
+**Portrait Fallback resolution:**
+1. `user.avatar` if set and not default placeholder
+2. `game.settings.get('core', 'defaultToken')` (system default)
+3. `'icons/svg/mystery-man.svg'` (Foundry built-in fallback)
+
+Access via adapter: `adapter.users.get(userId)?.avatar`.
+
+### StateRing CSS Spec (from UX spec §6.4)
+
+```less
+// In styles/components/_roster-strip.less (or a new _state-ring.less)
+.sp-state-ring--solid {
+  box-shadow: 0 0 0 2px var(--sp-state-color);
+}
+.sp-state-ring--dashed {
+  outline: 2px dashed var(--sp-state-color);
+  outline-offset: 2px;
+}
+.sp-state-ring--pending {
+  box-shadow: 0 0 0 2px var(--sp-state-color);
+  // animation added only under no-preference:
+}
+.sp-state-ring--revert {
+  box-shadow: 0 0 0 2px var(--sp-urgency-director);
+}
+
+@media (prefers-reduced-motion: no-preference) {
+  .sp-state-ring--pending {
+    animation: sp-pulse 2s ease-in-out infinite;
+  }
+  @keyframes sp-pulse {
+    0%, 100% { opacity: 1; }
+    50%       { opacity: 0.4; }
+  }
+}
+```
+
+**Ring variant per state:**
+| State | Ring class |
+|---|---|
+| `active` | `--solid` |
+| `hidden` | `--dashed` |
+| `self-muted` | `--solid` |
+| `offline` | (no ring) |
+| `cam-lost` | `--dashed` |
+| `reconnecting` | `--solid` + pulse |
+| `never-connected` | (no ring) |
+| `ghost` | `--solid` dotted variant |
+| `pending` | `--pending` (animated pulse) |
+| revert flash | `--revert` (200ms amber, then restore) |
+
+### AV Tile DOM Integration (AVTileAdapter)
+
+**Tile selector:** Foundry AV tiles have `data-user-id` attribute. Stable selector:
+```js
+document.querySelector(`.camera-view[data-user-id="${userId}"]`)
+// or: .user-camera[data-user-id="${userId}"]  — check actual Foundry v14 DOM
+// Test with real Foundry to confirm stable selector — use console.log to inspect ui.webrtc.element in dev
+```
+
+**mount() idempotency pattern:**
+```js
+mount(userId, element) {
+  const tile = this._findTile(userId);
+  if (!tile) {
+    console.warn('[ScryingPool] AVTileAdapter.mount: tile not found for', userId);
+    return;
+  }
+  // Idempotency: check for existing element with same data-sp-role
+  const role = element.dataset.spRole;
+  const existing = tile.querySelector(`[data-sp-role="${role}"]`);
+  if (existing) {
+    existing.replaceWith(element);  // update in place
+    return;
+  }
+  tile.appendChild(element);
+}
+```
+
+**State class isolation:** use `setStateClass()` to ensure only one `sp-state-*` class is ever present:
+```js
+setStateClass(userId, stateName) {
+  const tile = this._findTile(userId);
+  if (!tile) {
+    console.warn('[ScryingPool] AVTileAdapter.setStateClass: tile not found for', userId);
+    return;
+  }
+  // Remove all sp-state-* classes, add new one
+  const existing = [...tile.classList].filter(c => c.startsWith('sp-state-'));
+  existing.forEach(c => tile.classList.remove(c));
+  if (stateName) tile.classList.add(`sp-state-${stateName}`);
+}
+```
+
+### Template Structure (roster-strip.hbs)
+
+Replace the placeholder with actual ApplicationV2 template structure. The template is rendered inside the Foundry Application shell:
+
+```hbs
+{{!-- ScryingPoolStrip — floating GM control strip --}}
+<div class="scrying-pool scrying-pool-strip{{#if isExpanded}} is-expanded{{/if}}"
+     role="complementary"
+     aria-label="Scrying Pool">
+
+  {{!-- Expand/collapse toggle --}}
+  <button class="sp-strip__toggle" data-action="toggle-expanded"
+          aria-label="{{#if isExpanded}}Collapse Scrying Pool{{else}}Expand Scrying Pool{{/if}}"
+          aria-expanded="{{isExpanded}}">
+    <i class="fas fa-chevron-{{#if isExpanded}}left{{else}}right{{/if}}"></i>
+  </button>
+
+  {{!-- Participant list --}}
+  <ul class="sp-strip__participants" role="list">
+    {{#if isEmpty}}
+      {{!-- EmptyStatePanel --}}
+      <li class="sp-strip__empty-state" role="listitem">
+        <i class="fas fa-eye sp-empty__icon" aria-hidden="true"></i>
+        <span class="sp-empty__text">No participants yet</span>
+      </li>
+    {{else}}
+      {{#each participants}}
+        <li class="sp-strip__participant-item" role="listitem">
+          {{!-- ParticipantAvatar (44×44px container) --}}
+          <button class="sp-participant-avatar sp-state-{{state}}{{#if hasPendingOp}} sp-state-pending{{/if}}"
+                  data-user-id="{{userId}}"
+                  data-action="open-popover"
+                  role="button"
+                  aria-label="{{name}} — {{stateLabel}}"
+                  aria-pressed="false">
+
+            {{!-- Avatar image (32px rounded) --}}
+            <img class="sp-avatar__img" src="{{avatarSrc}}" alt="" aria-hidden="true" />
+
+            {{!-- StateRing (applied via CSS on parent button) --}}
+            {{!-- Corner badge (12px bottom-right) --}}
+            <span class="sp-avatar__corner-badge" aria-hidden="true">
+              {{!-- Icon rendered via CSS ::before content --}}
+            </span>
+
+            {{!-- Expanded view: name row --}}
+            {{#if ../isExpanded}}
+              <span class="sp-avatar__name">{{name}}</span>
+            {{/if}}
+          </button>
+        </li>
+      {{/each}}
+    {{/if}}
+  </ul>
+
+  {{!-- StripOverlayLayer — owns ActionPopover + ConfirmationBar --}}
+  <div class="sp-strip__overlay-layer"
+       aria-hidden="true"
+       style="position: absolute; inset: 0; pointer-events: none; overflow: visible;"></div>
+</div>
+```
+
+### ScryingPoolStrip — Application vs ApplicationV2
+
+FoundryVTT v14 introduces `ApplicationV2` with PARTS, but the simpler `Application` base class still works and is more straightforward for this pattern. Use `Application` for Story 1.5 to avoid ApplicationV2 PARTS complexity:
+
+```js
+export class ScryingPoolStrip extends Application {
+  static get defaultOptions() {
+    return foundry.utils.mergeObject(super.defaultOptions, {
+      id: 'scrying-pool-strip',
+      template: 'modules/video-view-manager/templates/roster-strip.hbs',
+      popOut: true,
+      resizable: false,
+      title: 'Scrying Pool',
+      classes: ['scrying-pool-strip'],
+    });
+  }
+}
+```
+
+If `ApplicationV2` is strongly preferred (e.g., for future PARTS-based rendering), the pattern changes to:
+```js
+export class ScryingPoolStrip extends foundry.applications.api.ApplicationV2 {
+  static PARTS = { strip: { template: '...' } };
+}
+```
+
+**Dev agent's call:** Use `Application` for simplicity unless you have a specific reason to use `ApplicationV2`. Document the choice in the class JSDoc.
+
+### Position Persistence Pattern
+
+User flag key: `video-view-manager.stripState` (note: world settings use `scrying-pool.` prefix but user flags use module ID `video-view-manager`).
+
+```js
+// Save on close
+game.user.setFlag('video-view-manager', 'stripState', {
+  left: this.position.left,
+  top: this.position.top,
+  open: false,
+  expanded: this._isExpanded,
+});
+
+// Load on open
+const saved = game.user.getFlag('video-view-manager', 'stripState');
+if (saved?.left !== undefined) {
+  options.left = saved.left;
+  options.top = saved.top;
+}
+this._isExpanded = saved?.expanded ?? true; // default expanded on first open
+```
+
+### OpId and Revision for Action Dispatch
+
+`ScryingPoolStrip._dispatchAction(participantId)` needs to call `scryingPoolController.action(source, participantId, targetState, opId, baseRevision)`.
+
+- **opId:** generate via `import { generateOpId } from '../../utils/uuid.js'` then `const opId = generateOpId()`
+- **baseRevision:** `scryingPoolController._revisions.get(participantId) ?? 0` — BUT this accesses a private field. Better pattern: expose a public `getRevision(participantId)` method on `ScryingPoolController`. This is a Story 1.5 addition to the Story 1.4 class.
+  - ADD `getRevision(participantId)` to `src/core/ScryingPoolController.js`: `return this._revisions.get(participantId) ?? 0;`
+  - This is a minor non-breaking addition to the Story 1.4 file.
+- **targetState:** `stateStore.getState(participantId) === 'hidden' ? 'active' : 'hidden'` — toggle logic. If current state is NOT hidden → hide; if hidden → show.
+
+### First-Encounter Tooltip (firstHideTooltip flag)
+
+On first hover over the primary CTA button in `ActionPopover` (`firstHideTooltip` flag not set):
+- Set `data-tooltip` to `"Hide this participant from other players."`
+- On mouseenter: check `localStorage.getItem('scrying-pool.firstHideTooltip')` — if unset, show extended tooltip and set flag via `localStorage.setItem('scrying-pool.firstHideTooltip', '1')`
+- Subsequent hovers: canonical label only
+
+Note: `firstHideTooltip` is stored in `localStorage` (client-side, session-local) per the architecture decision for v1.0. See architecture §Data Architecture.
+
+### EmptyStatePanel Animation
+
+```less
+// In _roster-strip.less
+.sp-empty__icon {
+  display: block;
+  // Static by default; animation only under no-preference
+}
+
+@media (prefers-reduced-motion: no-preference) {
+  .sp-empty__icon {
+    animation: sp-breathe 3s ease-in-out infinite;
+  }
+  @keyframes sp-breathe {
+    0%, 100% { opacity: 0.6; transform: scale(1);    }
+    50%       { opacity: 1.0; transform: scale(1.05); }
+  }
+}
+```
+
+### Existing Files Being Modified
+
+**`module.js`** — current ready hook ends with:
+```js
+  try {
+    visibilityManager.init();
+    scryingPoolController.init();
+  } catch (err) {
+    console.error('[ScryingPool] Module initialization failed:', err);
+    throw err;
+  }
+```
+
+After `scryingPoolController.init()`, add the Story 1.5 wiring block inside the same try/catch.
+
+**`src/core/ScryingPoolController.js`** — add public `getRevision(participantId)` method:
+```js
+/** Returns the last confirmed revision for a participant (0 if unknown). */
+getRevision(participantId) {
+  return this._revisions.get(participantId) ?? 0;
+}
+```
+
+### Hooks Used in This Story
+
+| Hook | Direction | Who calls | Who listens |
+|------|-----------|-----------|-------------|
+| `scrying-pool:stateChanged` | Hooks.callAll | StateStore | RoleRenderer (applies CSS to AV tiles) |
+| `scrying-pool:controllerAction` | Hooks.callAll | ScryingPoolController | ScryingPoolStrip (re-render), ActionPopover (disable during pending) |
+| `updateUser` | Hooks.on | Foundry core | RoleRenderer (mid-session role change rebuild) |
+
+### OQ-1 Reminder
+
+`adapter.webrtc` is ALWAYS `null` in production (CSS fallback path confirmed by Story 1.2 spike). The webrtcMode will be `'css-fallback'`. `VisibilityManager._onStateChanged()` is already a no-op when `adapter.webrtc` is null. `RoleRenderer` applies CSS/DOM state — no webrtc dependency.
+
+### Test Patterns
+
+**Testing AVTileAdapter (happy-dom):**
+```js
+import { AVTileAdapter } from '../../../src/ui/shared/AVTileAdapter.js';
+import { createFoundryAdapterMock } from '../../helpers/foundryAdapterMock.js';
+
+// happy-dom provides document — set up tile DOM
+beforeEach(() => {
+  document.body.innerHTML = `
+    <div class="camera-view" data-user-id="user-1"></div>
+  `;
+});
+
+test('mount() is idempotent', () => {
+  const adapter = createFoundryAdapterMock();
+  const avAdapter = new AVTileAdapter(adapter);
+  const el = document.createElement('div');
+  el.dataset.spRole = 'lock-overlay';
+  avAdapter.mount('user-1', el);
+  avAdapter.mount('user-1', el); // second call — must not duplicate
+  const tile = document.querySelector('[data-user-id="user-1"]');
+  expect(tile.querySelectorAll('[data-sp-role="lock-overlay"]').length).toBe(1);
+});
+```
+
+**Testing RoleRenderer:**
+```js
+import { vi } from 'vitest';
+import { RoleRenderer } from '../../../src/ui/RoleRenderer.js';
+import { createFoundryAdapterMock } from '../../helpers/foundryAdapterMock.js';
+
+beforeEach(() => {
+  vi.stubGlobal('Hooks', { on: vi.fn(), once: vi.fn(), off: vi.fn(), callAll: vi.fn() });
+});
+afterEach(() => { vi.unstubAllGlobals(); });
+
+function makeAVTileAdapter() {
+  return { mount: vi.fn(), unmount: vi.fn(), setStateClass: vi.fn(), disconnect: vi.fn(), onTileRerender: vi.fn() };
+}
+```
+
+**Testing ScryingPoolStrip (logic isolation):**
+Extract business logic into pure functions where possible (e.g., `resolveTargetState(currentState)`, `buildParticipantData(users, stateStore)`) and test those directly. For the Application class itself:
+```js
+// Stub Application globally
+vi.stubGlobal('Application', class { static get defaultOptions() { return {}; } });
+```
+
+**General rules (same as Story 1.4):**
+- `createFoundryAdapterMock()` — canonical mock, no ad-hoc stubs
+- Named exports only
+- JSDoc `/** ... */` above every exported class
+- `async/await` not `.then()`
+- Guard clauses with early return
+- `console.warn('[ScryingPool]', ...)` prefix on all console calls
+
+### ESLint / TypeScript Notes (Learnings from Stories 1.3 + 1.4)
+
+- Add JSDoc class comment (`/** ... */`) above EVERY exported class — `jsdoc/require-jsdoc` rule
+- Use `// eslint-disable-next-line no-unused-vars` (line comment) on the line ABOVE a `catch (_)` binding
+- `Application`/`Hooks`/`game`/`ui` globals are declared in `src/types/foundry-globals.d.ts` — do NOT add new declarations for already-declared globals
+- `foundry.utils.mergeObject` is the v14 way to extend `defaultOptions`
+- If adding `game.user.getFlag(...)` calls, check that `game.user` is declared in `foundry-globals.d.ts`; if not, add the `setFlag`/`getFlag` surface to it (use `declare const game: { user: { setFlag: ..., getFlag: ..., ... } }`)
+- `localStorage` is a browser global — no declaration needed
+- Pre-existing lint errors in `scripts/package.mjs` (7 errors) are not this story's scope — do NOT fix them

+## Dev Agent Record
+
+### Agent Model Used
+
+Claude Sonnet 4.6 (claude-sonnet-4.6)
+
+### Debug Log References
+
+- ESLint no-undef: `Application` in ScryingPoolStrip.js — fixed with `/* global Application */` comment. `typeof Application` is exempt from no-undef but direct reference in ternary is not.
+- ESLint no-unused-vars: `spy` in RoleRenderer.test.js bulk-payload test — removed.
+- TypeScript TS2488: `[...tile.classList]` spread on DOMTokenList — replaced with `Array.from(tile.classList)`.
+- `showFirstOpenTip` undefined in `activateListeners` — was referencing a variable from `getData()` scope; fixed to re-evaluate from `game.user.getFlag()` directly.
+
+### Completion Notes List
+
+- AVTileAdapter (24 tests): Full TDD red→green. `mount()` idempotent via data-sp-role key, `unmount()` removes [data-sp-mount] children, `setStateClass()` swaps sp-state-* classes, `onTileRerender()` uses MutationObserver per userId, `disconnect()` cleans all observers.
+- RoleRenderer (20 tests): TDD red→green with `vi.mock(ScryingPoolStrip)` + `vi.stubGlobal(Hooks)`. Registers 3 hooks in `init()`, handles stateChanged/controllerAction/updateUser. `openStrip()` lazily constructs ScryingPoolStrip singleton.
+- ScryingPoolStrip (23 tests): TDD red→green. Tests cover LABELS immutability, `resolveTargetState()`, `buildParticipantList()`, `getData()`, `defaultOptions`. ActionPopover implemented as internal (non-exported) class with `<dialog>` + Esc cancel + backdrop click dismiss + firstHideTooltip localStorage.
+- ScryingPoolController: Added `getRevision()` and `hasPendingOp()` public methods (non-breaking).
+- module.js: Wired AVTileAdapter + RoleRenderer with `game.webrtc !== null` guard for AC-13.
+- templates/roster-strip.hbs: Full HBS template with participants list, EmptyStatePanel, expand toggle, overlay layer, firstStripOpen tip.
+- styles/components/_roster-strip.less: Full CSS — StateRing variants, ParticipantAvatar layout, strip collapsed/expanded via max-width transition, AV tile overlays, EmptyStatePanel breathing animation, context menu, ActionPopover — all animations gated under `prefers-reduced-motion: no-preference`.
+- Pipeline: 248 tests (181 baseline + 67 new), 0 lint errors (pre-existing 7 in scripts/package.mjs untouched), 0 typecheck errors, build passes.

+# Story 1.6: Player Camera Status Badge
+
+Status: done
+
+## Story
+
+As a **player**,
+I want to always see whether my own camera feed is visible to the table, and understand what it means on first encounter,
+So that I'm never confused or surveilled without knowing it.
+
+## Acceptance Criteria
+
+1. **Given** a player is connected with AV enabled  
+   **When** the module is active  
+   **Then** a persistent `VisibilityBadge` appears on their own AV tile  
+   **And** the badge is visible only to the owning player (not to other players or the GM)  
+   **And** `role="status"`, `aria-live="polite"`, `aria-label="Camera visibility: [state label]"` are set  
+   **And** badge tokens are declared on `:root` (badge mounted outside `.scrying-pool` root, using `AVTileAdapter` from Story 1.5)
+
+2. **Given** a player's state is anything other than `active`  
+   **When** the badge renders  
+   **Then** it shows the correct vocabulary-partition label:
+   - `hidden` → "Hidden from table"
+   - `self-muted` → "Camera paused"
+   - `offline` → "Not connected"
+   - `cam-lost` → "Camera unavailable"
+   - `reconnecting` → "Rejoining view"
+   - `never-connected` → "Not yet connected"
+   - `ghost` → "Leaving"
+   - `active` → no label shown (null)
+
+3. **Given** the GM changes a player's visibility state  
+   **When** the socket broadcast completes  
+   **Then** the player's `VisibilityBadge` updates within 500ms
+
+4. **Given** `firstBadgeEncounter` user flag is not set and a state change occurs  
+   **When** the badge updates  
+   **Then** `FirstEncounterPanel` appears with a plain-language explanation  
+   **And** a 10s auto-collapse timer starts  
+   **And** `mouseenter` or `:focus-within` on the panel pauses the timer (resumes on leave/blur)  
+   **And** "Got it" sets `firstBadgeEncounter` and immediately closes the panel  
+   **And** the panel is `aria-modal="false"`, `role="dialog"`, and is NOT a focus trap
+
+5. **Given** the 10s timer expires without interaction  
+   **When** auto-collapse fires  
+   **Then** the panel collapses via `max-height` fold animation (300ms ease-out) into a persistent chip  
+   **And** the chip is focusable and keyboard-activatable, re-opening `VisibilityDetailsPanel` on activation  
+   **And** if focus is inside the panel when collapse fires, focus is moved to the chip  
+   **And** subsequent state changes do NOT re-show the panel (flag is permanently set)  
+   **And** `clearTimeout` is called on "Got it" click and on `_onClose()` teardown to prevent ghost timers
+
+6. **Given** a player clicks their `VisibilityBadge` or the collapsed chip  
+   **When** `VisibilityDetailsPanel` opens  
+   **Then** it shows: who changed the state ("Hidden by: [GM name]" / "Connection issue" / "Scene preset: [name]"), what the state means in plain language, and a reassurance note  
+   **And** when state is `hidden`, the audience list is suppressed and replaced with reassurance copy: "Other players cannot see your feed"  
+   **And** a stale-data indicator appears when `ScryingPoolController` is unavailable  
+   **And** the panel is a focus-trapped `<dialog>` with `aria-modal="true"`  
+   **And** Esc, click-outside, or "Close" button dismisses it and returns focus to the triggering element
+
+7. **Given** `AVTileAdapter.mount(userId, badgeElement)` is called and the AV tile DOM node is not found  
+   **When** the call executes  
+   **Then** the adapter no-ops and logs `console.warn` without throwing (fail-open)
+
+8. **Given** Foundry re-renders the AV tile (detected via `MutationObserver`)  
+   **When** the re-render is detected  
+   **Then** the badge is updated in-place if possible; remove-and-reinsert only if structure requires full rebuild  
+   **And** `AVTileAdapter.disconnect()` is called on module teardown
+
+## Tasks / Subtasks
+
+- [x] Task 1: Create `src/ui/player/VisibilityBadge.js` (AC: 1, 2, 3, 4, 5, 6, 7, 8)
+  - [x] 1.1: Write failing tests in `tests/unit/ui/player/VisibilityBadge.test.js` first (TDD red)
+  - [x] 1.2: Implement `VisibilityBadge` class — constructor receives `(stateStore, controller, avTileAdapter, adapter)`; side-effect-free; store all deps
+  - [x] 1.3: Implement `init()` — resolve `currentUserId` from `adapter.users.current()?.id`; subscribe to `scrying-pool:stateChanged` hook; mount initial badge at current state; register `avTileAdapter.onTileRerender()` callback for re-mount resilience; no-op if no `currentUserId`
+  - [x] 1.4: Implement `_createBadgeElement(state)` — creates `<div class="sp-visibility-badge" data-sp-role="visibility-badge">` with correct ARIA attributes; applies label from `PLAYER_STATE_LABELS[state]`
+  - [x] 1.5: Implement `_onStateChanged(data)` — guard: only process `data.userId === this._currentUserId`; update badge element label + aria-label; call `avTileAdapter.mount(userId, badgeEl)` (idempotent); trigger `FirstEncounterPanel` if `_getFirstBadgeEncountered()` returns falsy
+  - [x] 1.6: Implement `_getFirstBadgeEncountered()` — `return adapter.users.current()?.getFlag('video-view-manager', 'firstBadgeEncounter') ?? false`
+  - [x] 1.7: Implement `_setFirstBadgeEncountered()` — `await adapter.users.current()?.setFlag('video-view-manager', 'firstBadgeEncounter', true)`
+  - [x] 1.8: Implement badge click handler → instantiate and open `VisibilityDetailsPanel` with current state + actor info
+  - [x] 1.9: Implement `teardown()` — call `avTileAdapter.disconnect()` and clean up hook listeners
+  - [x] 1.10: Green all VisibilityBadge tests
+
+- [x] Task 2: Implement `FirstEncounterPanel` class (inside `VisibilityBadge.js`) (AC: 4, 5)
+  - [x] 2.1: Write failing tests for `FirstEncounterPanel` (TDD red) — timer-based tests use `vi.useFakeTimers()`
+  - [x] 2.2: Implement `show(anchorEl)` — create and append panel element; `role="dialog"`, `aria-modal="false"`; start 10s `#collapseTimer`
+  - [x] 2.3: Implement timer pause: `mouseenter` / `mouseleave` on panel element; `focusin` / `focusout` events (not `:focus-within` directly — use event listeners)
+  - [x] 2.4: Implement "Got it" button handler — `clearTimeout(this.#collapseTimer)`, `this.#collapseTimer = null`, call `setFirstBadgeEncountered()`, then `_dismiss()` (removes panel from DOM)
+  - [x] 2.5: Implement `_collapse()` — set `max-height` animation via CSS class; after `transitionend` (or timeout fallback), replace panel with chip element; if active focus is inside panel, move focus to chip
+  - [x] 2.6: Implement chip element — `role="button"`, `tabindex="0"`; `click` and `keydown Enter/Space` → open `VisibilityDetailsPanel`
+  - [x] 2.7: Implement `_onClose()` — `clearTimeout(this.#collapseTimer)`, `this.#collapseTimer = null` (must be called in teardown to prevent ghost timers)
+  - [x] 2.8: Green all FirstEncounterPanel tests
+
+- [x] Task 3: Implement `VisibilityDetailsPanel` class (inside `VisibilityBadge.js`) (AC: 6)
+  - [x] 3.1: Write failing tests for `VisibilityDetailsPanel` (TDD red)
+  - [x] 3.2: Implement using native `<dialog>` element + `showModal()` — built-in focus trap + backdrop in modern browsers; `aria-modal="true"` attribute
+  - [x] 3.3: Implement `show(state, actor, triggerEl)` — create `<dialog>`, populate content, `document.body.appendChild(dialog)`, `dialog.showModal()`, store `triggerEl` for focus return
+  - [x] 3.4: Implement close handlers:
+    - Esc: native `<dialog>` handles; listen to `close` event → `_onClose()`
+    - Backdrop click: `dialog.addEventListener('click', e => { if (e.target === dialog) dialog.close(); })`
+    - "Close" button: `dialog.close()`
+  - [x] 3.5: Implement `_onClose()` — `dialog.remove()`, `this._triggerEl?.focus()` (return focus)
+  - [x] 3.6: Populate content per state — actor line, state explanation, audience (suppress + reassurance when `state === 'hidden'`), reassurance ("Your audio is active for all participants.")
+  - [x] 3.7: Handle stale data — show "Data may be outdated" note if controller is not available; for v1 this can check `controller != null`
+  - [x] 3.8: Green all VisibilityDetailsPanel tests
+
+- [x] Task 4: Implement `styles/components/_player-badge.less` (AC: 1, 2, 4, 5, 6)
+  - [x] 4.1: Replace stub content with full badge + panel CSS; remove incorrect scoping comment (see §CSS Exception note below)
+  - [x] 4.2: `.sp-visibility-badge` — `position: absolute; top: 0; left: 50%; transform: translateX(-50%);` for top-center tile injection; anatomy: mini StateRing (16px) + state icon + label text
+  - [x] 4.3: State label typography: `font-size: 0.6875rem` (11px), `letter-spacing: 0.02em`
+  - [x] 4.4: `FirstEncounterPanel` styles — `max-height` transition `300ms ease-out` for collapse; panel positioning relative to badge/tile
+  - [x] 4.5: Chip styles — small, focusable, matches badge visual language
+  - [x] 4.6: `VisibilityDetailsPanel` (`<dialog>`) styles — content layout; "Close" button; backdrop
+  - [x] 4.7: Gate ALL animations under `@media (prefers-reduced-motion: no-preference)`; add `.sp-visibility-badge { transition: none; animation: none; }` at top level before the media query
+
+- [x] Task 5: Update `module.js` (AC: 1)
+  - [x] 5.1: Add `import { VisibilityBadge } from './src/ui/player/VisibilityBadge.js';` at top of file
+  - [x] 5.2: Add `let visibilityBadge;` with other module-level variables
+  - [x] 5.3: In `Hooks.once('ready')` after `roleRenderer.init()` + `openStrip()` block:
+    ```js
+    if (!adapter.users.isGM()) {
+      visibilityBadge = new VisibilityBadge(stateStore, scryingPoolController, avTileAdapter, adapter);
+      visibilityBadge.init();
+    }
+    ```
+  - [x] 5.4: Update the init comment block at top of `module.js` to mention Story 1.6
+
+- [x] Task 6: Update `lang/en.json` with i18n keys
+  - [x] 6.1: Add badge state labels (hidden, self-muted, offline, cam-lost, reconnecting, never-connected, ghost)
+  - [x] 6.2: Add `FirstEncounterPanel` copy (title: "Your camera visibility changed.", body: "Audio continues normally.", "Got it" button label)
+  - [x] 6.3: Add `VisibilityDetailsPanel` copy ("Close", audience suppression text, stale data indicator text, reassurance text)
+
+- [x] Task 7: Update `src/types/foundry-globals.d.ts`
+  - [x] 7.1: Verify if `game.user.setFlag / getFlag` is declared; if not, add to existing `game` declaration (do NOT duplicate the `game` declaration — extend the `user` sub-object)
+
+- [x] Task 8: Verify full pipeline
+  - [x] 8.1: `npm run test` — all tests pass (expect ~20–30 new tests)
+  - [x] 8.2: `npm run lint` — 0 new lint errors
+  - [x] 8.3: `npm run typecheck` — 0 new typecheck errors
+  - [x] 8.4: `npm run build` — clean build
+
+## Dev Notes
+
+### Architecture Context
+
+Story 1.6 is the final story of Epic 1. It builds the player-facing visibility badge, completing the core visibility loop: GM hides/shows feeds (Story 1.5), and each player always sees their own camera state.
+
+**Component naming clarification (architecture doc vs story/UX spec):**
+The architecture doc places this in `src/ui/shared/PlayerStatusBadge.js`. The UX spec and story consistently use `VisibilityBadge`. Per the Story 1.5 precedent ("story spec takes precedence over architecture file-level names"), use:
+- Class: `VisibilityBadge` (+ `FirstEncounterPanel`, `VisibilityDetailsPanel`)
+- File: `src/ui/player/VisibilityBadge.js` (player-subtree — badge is never shown to GM)
+
+**Player-only enforcement:** The badge is instantiated in `module.js` only when `!adapter.users.isGM()`. Inside `init()`, it is mounted only on `adapter.users.current()?.id` — the player's OWN tile.
+
+### Init Order (EXACT — do not deviate)
+
+```
+Hooks.once('ready')
+  → stateStore.init()                                          // Story 1.3
+  → FoundryAdapter.probeCapability() + webrtcMode             // Story 1.3
+  → visibilityManager = new VisibilityManager(...)             // Story 1.4
+  → visibilityManager.init()                                   // Story 1.4
+  → socketHandler.setReady(...)                                // Story 1.4
+  → scryingPoolController = new ScryingPoolController(...)     // Story 1.4
+  → scryingPoolController.init()                               // Story 1.4
+  → avTileAdapter = new AVTileAdapter(adapter)                 // Story 1.5
+  → roleRenderer = new RoleRenderer(stateStore, scryingPoolController, avTileAdapter, adapter)  // Story 1.5
+  → roleRenderer.init()                                        // Story 1.5
+  → if isGM: roleRenderer.openStrip()                         // Story 1.5
+  → if !isGM: visibilityBadge = new VisibilityBadge(stateStore, scryingPoolController, avTileAdapter, adapter)  // Story 1.6 (NEW)
+              visibilityBadge.init()                           // Story 1.6 (NEW)
+  // Story 2.1: NotificationBus
+  // Story 2.2: DirectorsBoard (lazy, GM only)
+```
+
+`avTileAdapter` is **shared** between `RoleRenderer` (GM strip CSS) and `VisibilityBadge` (player badge injection) — one instance, injected into both.
+
+### Player State Vocabulary (CANONICAL — use exactly these strings)
+
+Source: epics.md Story 1.6 AC. This takes precedence over the UX spec §3.1 table.
+
+```js
+const PLAYER_STATE_LABELS = Object.freeze({
+  hidden:            'Hidden from table',
+  'self-muted':      'Camera paused',
+  offline:           'Not connected',
+  'cam-lost':        'Camera unavailable',
+  reconnecting:      'Rejoining view',
+  'never-connected': 'Not yet connected',
+  ghost:             'Leaving',
+  active:            null,   // no label displayed for active state
+});
+```
+
+❌ Do NOT use UX spec §3.1 alternatives: "Not visible to others", "Disconnected", "Rejoining" — wrong.
+
+### `firstBadgeEncounter` Storage — Architecture Decision
+
+**Use `game.user.setFlag` (Foundry user flag), NOT localStorage.**
+
+Access via `adapter.users.current()` (the Foundry User document returned by `FoundryAdapter.users.current()`):
+```js
+// Read flag:
+const encountered = adapter.users.current()?.getFlag('video-view-manager', 'firstBadgeEncounter') ?? false;
+
+// Write flag:
+await adapter.users.current()?.setFlag('video-view-manager', 'firstBadgeEncounter', true);
+```
+
+⚠️ UX spec §6.9 mentions `localStorage` — **ignore this.** Architecture decision (line 250) + story AC both mandate the user flag. The `localStorage` option was explicitly marked as a "v2 migration path."
+
+**Type declarations:** `foundry-globals.d.ts` does not currently declare `setFlag/getFlag` on `game.user`. Add them to the existing `game` declaration when encountered.
+
+### `AVTileAdapter` Integration (REUSE as-is from Story 1.5)
+
+`AVTileAdapter` is fully implemented (24 tests). Do NOT modify it.
+
+Badge element shape for idempotent mounting:
+```js
+const badgeEl = document.createElement('div');
+badgeEl.className = 'sp-visibility-badge';
+badgeEl.dataset.spRole = 'visibility-badge';   // ← key for AVTileAdapter idempotency
+badgeEl.setAttribute('role', 'status');
+badgeEl.setAttribute('aria-live', 'polite');
+badgeEl.setAttribute('aria-label', `Camera visibility: ${stateLabel ?? 'Active'}`);
+```
+
+Re-render resilience (Foundry AV tile DOM changes post-render):
+```js
+avTileAdapter.onTileRerender(currentUserId, () => {
+  this._mountBadge(this._currentState);  // re-mount after tile re-render
+});
+```
+
+### Internal Component Structure (one file, two inner classes)
+
+Mirror the ActionPopover pattern from Story 1.5 (ActionPopover is an internal class inside ScryingPoolStrip.js):
+
+```
+src/ui/player/VisibilityBadge.js
+  export class VisibilityBadge          ← wired into module.js; manages badge DOM + subscriptions
+  class FirstEncounterPanel             ← internal; created/owned by VisibilityBadge
+  class VisibilityDetailsPanel          ← internal; created/owned by VisibilityBadge
+```
+
+**`VisibilityBadge` responsibilities:**
+- Create + update badge DOM element; mount via `avTileAdapter`
+- Subscribe to `scrying-pool:stateChanged` (current user only)
+- Instantiate `FirstEncounterPanel` on first encounter
+- Instantiate `VisibilityDetailsPanel` on badge/chip click
+
+**`FirstEncounterPanel` responsibilities:**
+- Non-modal explanatory panel; 10s collapse timer
+- Pause timer on `mouseenter`/`focusin`; resume on `mouseleave`/`focusout`
+- "Got it" → set flag + dismiss; `clearTimeout` always
+- `max-height` fold animation → chip after collapse
+- `_onClose()` MUST `clearTimeout` (ghost timer prevention)
+
+**`VisibilityDetailsPanel` responsibilities:**
+- Native `<dialog>` + `showModal()` — built-in focus trap
+- 3-question content: actor, state meaning, audience
+- Dismiss: Esc (native) / backdrop click / "Close" button
+- Return focus to trigger element on close
+
+### CSS — `.sp-visibility-badge` Is the Documented `:root` Exception
+
+⚠️ **`styles/components/_player-badge.less` has an incorrect stub comment: "All selectors MUST be scoped under .scrying-pool."** This is wrong for badge styles — it's the documented exception.
+
+From Story 1.1 AC (line 258 epics.md): *"the VisibilityBadge :root exception is documented: badge tokens are declared on :root because the badge is mounted outside the .scrying-pool root"*
+
+**Correct approach:**
+```less
+// VisibilityBadge — this file is the DOCUMENTED EXCEPTION to .scrying-pool scoping.
+// The badge is injected into the AV tile DOM via AVTileAdapter — outside any .scrying-pool root.
+// Selectors here are top-level (not nested under .scrying-pool).
+// Badge-specific tokens are declared on :root so they are reachable from tile-adjacent DOM.
+// Source: Architecture §Token System + Story 1.1 AC (VisibilityBadge :root exception).
+
+.sp-visibility-badge { transition: none; animation: none; }
+
+@media (prefers-reduced-motion: no-preference) {
+  .sp-visibility-badge {
+    // badge-specific motion if any
+  }
+}
+
+:root {
+  --sp-badge-bg:   hsl(220, 15%, 10%);
+  --sp-badge-text: hsl(0, 0%, 85%);
+}
+
+.sp-visibility-badge {
+  position: absolute;
+  top: 0;
+  left: 50%;
+  transform: translateX(-50%);
+  // ...
+}
+```
+
+Note: All existing `--sp-state-*` tokens are ALREADY on `:root` via `_roster-strip.less` and `_base.less` — no need to re-declare them.
+
+### `FirstEncounterPanel` — Timer Ghost Prevention
+
+```js
+class FirstEncounterPanel {
+  #collapseTimer = null;
+
+  show(anchorEl) {
+    // ... create panel DOM, attach ...
+    this.#collapseTimer = setTimeout(() => this._collapse(), 10_000);
+    panel.addEventListener('mouseenter', () => this._pauseTimer());
+    panel.addEventListener('mouseleave', () => this._resumeTimer());
+    panel.addEventListener('focusin',    () => this._pauseTimer());
+    panel.addEventListener('focusout',   () => this._resumeTimer());
+  }
+
+  _pauseTimer()  { clearTimeout(this.#collapseTimer); this.#collapseTimer = null; }
+  _resumeTimer() { this.#collapseTimer = setTimeout(() => this._collapse(), 10_000); }
+
+  _onGotIt() {
+    clearTimeout(this.#collapseTimer);   // ← REQUIRED: ghost prevention
+    this.#collapseTimer = null;
+    this._setFirstBadgeEncountered();
+    this._dismiss();
+  }
+
+  _onClose() {
+    clearTimeout(this.#collapseTimer);   // ← REQUIRED: ghost prevention on teardown
+    this.#collapseTimer = null;
+  }
+}
+```
+
+⚠️ Missing either `clearTimeout` creates ghost timers — they fire after the panel is gone and can cause null-pointer errors or re-render glitches.
+
+### `VisibilityDetailsPanel` — Native `<dialog>` Focus Trap
+
+`<dialog>` with `showModal()` provides native focus trapping in happy-dom and modern browsers:
+```js
+const dialog = document.createElement('dialog');
+dialog.setAttribute('aria-modal', 'true');
+// ... populate content ...
+document.body.appendChild(dialog);
+dialog.showModal();   // native focus trap + Esc handling + backdrop
+```
+
+- **Esc key:** `<dialog>` handles natively → dispatches `cancel` + `close` events; listen to `close` for cleanup
+- **Backdrop click:** `dialog.addEventListener('click', e => { if (e.target === dialog) dialog.close(); })`
+- **"Close" button:** calls `dialog.close()`
+- **Focus return:** `dialog.addEventListener('close', () => { dialog.remove(); this._triggerEl?.focus(); })`
+
+Do NOT build a manual focus trap.
+
+### Hooks Used by This Story
+
+```
+Hooks.on('scrying-pool:stateChanged', data => { /* update badge for currentUserId only */ })
+```
+
+No new Foundry hooks introduced. `scrying-pool:stateChanged` was established in Story 1.3 and is emitted by `StateStore` on every mutation (via `Hooks.callAll`).
+
+### Import Boundaries (HARD — ESLint enforced)
+
+```
+src/ui/player/VisibilityBadge.js → may import: src/core/, src/contracts/, src/utils/
+```
+❌ Do NOT import `src/foundry/FoundryAdapter` — FoundryAdapter comes through constructor injection.
+❌ `src/core/` must NOT import `src/ui/` — no circular dependencies.
+
+### Test Patterns
+
+**Setup (happy-dom provides document):**
+```js
+import { describe, it, expect, beforeEach, afterEach, vi } from 'vitest';
+import { VisibilityBadge } from '../../../../src/ui/player/VisibilityBadge.js';
+import { createFoundryAdapterMock } from '../../../helpers/foundryAdapterMock.js';
+
+beforeEach(() => {
+  document.body.innerHTML = `<div class="camera-view" data-user-id="user-player"></div>`;
+  vi.stubGlobal('Hooks', { on: vi.fn(), once: vi.fn(), off: vi.fn(), callAll: vi.fn() });
+});
+afterEach(() => { vi.unstubAllGlobals(); });
+```
+
+**Adapter mock with user flag support:**
+```js
+function makeAdapter({ userId = 'user-player', isGM = false, firstBadgeEncountered = false } = {}) {
+  const mockUser = {
+    id: userId,
+    getFlag: vi.fn().mockReturnValue(firstBadgeEncountered),
+    setFlag: vi.fn().mockResolvedValue(undefined),
+  };
+  return createFoundryAdapterMock({
+    users: {
+      current: () => mockUser,
+      isGM: () => isGM,
+      get: () => mockUser,
+      all: () => [mockUser],
+    },
+  });
+}
+```
+
+**AVTileAdapter mock:**
+```js
+function makeAVTileAdapter() {
+  return {
+    mount:           vi.fn(),
+    unmount:         vi.fn(),
+    setStateClass:   vi.fn(),
+    onTileRerender:  vi.fn(),
+    disconnect:      vi.fn(),
+  };
+}
+```
+
+**Fake timers for FirstEncounterPanel:**
+```js
+it('collapses after 10s idle', () => {
+  vi.useFakeTimers();
+  // ... show panel ...
+  vi.advanceTimersByTime(10_001);
+  // ... assert chip exists, panel gone ...
+  vi.useRealTimers();
+});
+```
+
+**Testing VisibilityDetailsPanel:**
+- `happy-dom` supports `<dialog>.showModal()` — test it is called
+- Test backdrop click (`event.target === dialog`) triggers close
+- Test "Close" button calls `dialog.close()`
+- Test `triggerEl.focus()` called after close
+
+### ESLint / TypeScript Notes (Learnings from Stories 1.3–1.5)
+
+- JSDoc `/** ... */` class comment required on EVERY exported class (`jsdoc/require-jsdoc`)
+- Use `// eslint-disable-next-line no-unused-vars` on line ABOVE a `catch (_)` binding
+- `Hooks`/`game`/`ui` globals declared in `src/types/foundry-globals.d.ts` — add `setFlag`/`getFlag` to `game.user` if missing; NEVER add a second `declare const game` — extend the existing one's `user` sub-property
+- Named exports only: `export class VisibilityBadge` — never `export default`
+- Pre-existing lint errors in `scripts/package.mjs` (7 errors) — NOT in scope, do not touch
+- `async/await` not `.then()`; guard clauses with early return; `null` not `undefined` from public APIs
+
+### Project Structure Notes
+
+**Files to create:**
+```
+src/ui/player/VisibilityBadge.js                     ← NEW; VisibilityBadge + FirstEncounterPanel + VisibilityDetailsPanel
+tests/unit/ui/player/VisibilityBadge.test.js         ← NEW
+```
+
+**Files to update:**
+```
+module.js                                            ← add import + init badge for !isGM clients
+styles/components/_player-badge.less                ← replace stub with full badge/panel CSS
+lang/en.json                                        ← add badge i18n keys
+src/types/foundry-globals.d.ts                      ← add setFlag/getFlag to game.user if absent
+```
+
+**Files NOT changed:**
+- `src/ui/shared/AVTileAdapter.js` — reused as-is (fully implemented Story 1.5)
+- `src/ui/RoleRenderer.js` — no changes
+- `src/core/` files — no changes
+- `src/contracts/` — no changes
+- `tests/helpers/foundryAdapterMock.js` — no structural changes needed; the `current()` override in individual test `makeAdapter()` helpers is sufficient
+
+**Import boundary check for new files:**
+```
+src/ui/player/VisibilityBadge.js → imports: src/core/ ✅, src/contracts/ ✅, src/utils/ ✅
+```

+- Timer collapse tests required advancing fake timers in two steps: 10_001ms for the collapse timeout, then 301ms for the 300ms CSS transition replacement timer. Reason: `vi.advanceTimersByTime(N)` only fires timers scheduled before the advance boundary — nested timers scheduled during callback execution need a second advance call.

+# Story 2.1: NotificationBus & Notification Verbosity
+
+Status: done
+
+## Story
+
+As a **player**,
+I want to receive a plain-language notification whenever the GM changes my camera's visibility, and control how many notifications I see,
+so that I'm never left wondering what happened to my feed without being overwhelmed by alerts.
+
+## Acceptance Criteria
+
+1. **Given** the GM changes a participant's visibility state
+   **When** the socket broadcast is received by all clients
+   **Then** a toast notification fires via `ui.notifications` reading "GM hid [Name]'s camera" or "GM showed [Name]'s camera"
+
+2. **Given** the affected participant's own client
+   **When** any visibility change is received
+   **Then** they receive a distinct personal notification regardless of their verbosity setting
+   **And** this personal message cannot be suppressed by the GM
+
+3. **Given** the GM changes the same participant's state multiple times within 3 seconds
+   **When** the `NotificationBus` coalescing timer fires
+   **Then** a single coalesced notification fires reporting the final state and change count
+   **And** if the net state equals the original state, no notification fires at all
+
+4. **Given** a user's verbosity setting is `GM Only`
+   **When** another participant's camera is changed
+   **Then** only the GM and the affected participant receive a notification (other players see nothing)
+
+5. **Given** a user's verbosity setting is `Silent`
+   **When** any participant's camera is changed
+   **Then** that user receives no notification unless they are the affected participant
+
+6. **Given** a user changes their verbosity setting in module settings
+   **When** the change is saved
+   **Then** it persists to their client-level user setting and takes effect immediately
+
+7. **Given** `Hooks.once('ready')` fires
+   **When** `NotificationBus` is constructed and `init()` is called
+   **Then** it subscribes to `scrying-pool:stateChanged` hook and holds `Map<participantId, {timer, prevState, lastState, changeCount}>`
+
+## Tasks / Subtasks
+
+- [x] Task 1: Create `src/notifications/NotificationBus.js` (AC: 1, 2, 3, 4, 5, 6, 7)
+  - [x] 1.1: Write failing tests in `tests/unit/notifications/NotificationBus.test.js` first (TDD red) — use `vi.useFakeTimers()` for coalescing timer tests
+  - [x] 1.2: Implement `NotificationBus` class — constructor receives `(adapter)`; side-effect-free; store `adapter`; init `#coalesceMap = new Map()`; init `_hookId = null`
+  - [x] 1.3: Implement `init()` — register hook: `this._hookId = Hooks.on('scrying-pool:stateChanged', this._onStateChanged.bind(this))`
+  - [x] 1.4: Implement `_onStateChanged(data)` — guard: `data.userId` must be present; check if personal (`data.userId === adapter.users.current()?.id`); if personal → `_notifyPersonal(data)`; else → check verbosity then `_enqueue(data)`
+  - [x] 1.5: Implement `_notifyPersonal(data)` — fire immediate notification regardless of verbosity: `"GM has hidden your camera. Your portrait is shown to other Participants."` (hidden) or `"Your camera is now visible to the table."` (other states)
+  - [x] 1.6: Implement `_enqueue(userId, newState, prevState)` — if existing entry: `clearTimeout(existing.timer)`, update `lastState`, increment `changeCount`; if new: set `{timer:null, prevState, lastState:newState, changeCount:1}`; set new debounce timer (`setTimeout(() => this._flush(userId), 3000)`)
+  - [x] 1.7: Implement `_flush(userId)` — get + delete entry from `#coalesceMap`; net-zero guard: if `entry.lastState === entry.prevState` → return (no notification); resolve display name via `adapter.users.get(userId)?.name ?? userId`; fire `adapter.notifications.info(msg)` with correct message template
+  - [x] 1.8: Implement `teardown()` — `Hooks.off('scrying-pool:stateChanged', this._hookId)`, clear all pending timers from `#coalesceMap`, clear the map
+  - [x] 1.9: Green all NotificationBus tests
+
+- [x] Task 2: Register `notificationVerbosity` client setting in `module.js` (AC: 4, 5, 6)
+  - [x] 2.1: In `Hooks.once('init')`, add: `adapter.settings.register('notificationVerbosity', { scope: 'client', config: true, type: String, choices: { all: 'All', 'gm-only': 'GM Only', silent: 'Silent' }, default: 'all' })`
+  - [x] 2.2: Add import `NotificationBus` from `'./src/notifications/NotificationBus.js'`
+  - [x] 2.3: Declare `let notificationBus;` at module scope
+  - [x] 2.4: In `Hooks.once('ready')`, after `visibilityBadge.init()`, add: `notificationBus = new NotificationBus(adapter); notificationBus.init();` (runs for BOTH GM and player clients)
+
+- [x] Task 3: Add i18n keys for notification messages in `lang/en.json` (AC: 1, 2)
+  - [x] 3.1: Add `video-view-manager.notifications.gmHid` = `"GM hid {name}'s camera"`
+  - [x] 3.2: Add `video-view-manager.notifications.gmShowed` = `"GM showed {name}'s camera"`
+  - [x] 3.3: Add `video-view-manager.notifications.personalHidden` = `"GM has hidden your camera. Your portrait is shown to other Participants."`
+  - [x] 3.4: Add `video-view-manager.notifications.personalShowed` = `"Your camera is now visible to the table."`
+  - [x] 3.5: Add setting label keys: `video-view-manager.settings.notificationVerbosity.label`, `.hint`, `.choices.all`, `.choices.gm-only`, `.choices.silent`
+
+- [x] Task 4: Deferred debt cleanup — fold in from `deferred-work.md` (epic 1 carry-over)
+  - [x] 4.1: Fix `_revisions` Map leak in `ScryingPoolController.js` — wire `cleanupParticipant(userId)` on `userConnected` disconnect event in `init()`; store hook ID for teardown; tests added
+  - [x] 4.2: Add listener cleanup to `ScryingPoolController` — store echo handler ref as `_echoHandler` in `init()`, expose full `teardown()` with `socket.off` + `hooks.off` + `cleanupAll()`; tests added
+  - [x] 4.3: Add listener cleanup to `VisibilityManager` — store hook ID as `_stateChangedHookId` in `init()`; add `teardown()` calling `adapter.hooks.off`; tests added
+  - [x] 4.4: Echo revision type validation — ALREADY PRESENT in `ScryingPoolController._onEcho()` (`Number.isFinite(revision)` guard at validation step); no action needed
+
+- [x] Task 5: Implement `styles/components/_notification.less` minimal styles (AC: 1)
+  - [x] 5.1: Replaced stub comment with scoped `.scrying-pool` placeholder block; native `ui.notifications` styling suffices for toasts
+
+- [x] Task 6: Pipeline verification
+  - [x] 6.1: `npm run lint` exits 0 for all modified files — pre-existing `scripts/package.mjs` errors unrelated to this story
+  - [x] 6.2: `npm run test` exits 0 — 335 tests passing (296 baseline + 28 NotificationBus + 7 teardown ScryingPoolController + 4 teardown VisibilityManager)
+
+## Dev Notes
+
+### File Location — New Directory Required
+
+```
+src/notifications/NotificationBus.js   ← NEW (create directory)
+tests/unit/notifications/NotificationBus.test.js  ← NEW (create directory)
+```
+
+### Import Boundary — HARD RULE
+
+`src/notifications/` may only import from:
+- `src/core/`
+- `src/contracts/`
+- `src/utils/`
+
+❌ No imports from `src/foundry/`, `src/ui/`, or `src/presets/`.  
+ESLint enforces this via `import/no-restricted-paths` — lint will catch violations.
+
+### Constructor Pattern (Side-Effect-Free)
+
+```js
+// src/notifications/NotificationBus.js
+/**
+ * NotificationBus — coalesced toast layer above ui.notifications.
+ * Subscribes to scrying-pool:stateChanged and coalesces rapid GM visibility
+ * changes into a single toast per participant per 3-second window.
+ *
+ * Import boundary: src/notifications/ → src/core/, src/contracts/, src/utils/ ONLY.
+ * @module notifications/NotificationBus
+ */
+export class NotificationBus {
+  /** @type {Map<string, {timer: ReturnType<typeof setTimeout>|null, prevState: string, lastState: string, changeCount: number}>} */
+  #coalesceMap = new Map();
+  #hookId = null;
+
+  /**
+   * @param {{ notifications: {info(m:string):void, warn(m:string):void},
+   *            users: {get(id:string):unknown, current():unknown, isGM():boolean},
+   *            settings: {get(key:string):unknown} }} adapter
+   */
+  constructor(adapter) {
+    this._adapter = adapter;
+  }
+
+  /** Register hook listener. Call from module.js Hooks.once('ready'). */
+  init() {
+    this.#hookId = Hooks.on('scrying-pool:stateChanged', (data) => this._onStateChanged(data));
+  }
+
+  teardown() {
+    if (this.#hookId != null) {
+      Hooks.off('scrying-pool:stateChanged', this.#hookId);
+      this.#hookId = null;
+    }
+    for (const entry of this.#coalesceMap.values()) clearTimeout(entry.timer);
+    this.#coalesceMap.clear();
+  }
+}
+```
+
+### Verbosity Setting — `client` Scope (NOT world)
+
+Registered in `module.js` `Hooks.once('init')` via the adapter (like all other settings):
+
+```js
+// module.js Hooks.once('init') — add after showGMSelfFeed registration:
+adapter.settings.register('notificationVerbosity', {
+  scope: 'client',   // ← client scope: each user's own preference
+  config: true,      // visible in module settings UI
+  type: String,
+  choices: {
+    all:      'All',      // default: all clients see all notifications
+    'gm-only': 'GM Only', // only GM + affected participant notified
+    silent:   'Silent',   // only affected participant notified
+  },
+  default: 'all',
+});
+```
+
+⚠️ `scope: 'client'` stores per-user on their local client. Takes effect immediately on `settings.get()` — no reload needed.
+
+### Verbosity Filter Logic
+
+```js
+_onStateChanged(data) {
+  const { userId, newState, previousState } = data;
+  const currentUserId = this._adapter.users.current()?.id;
+
+  // AC-2: Personal notification is never suppressed
+  if (userId === currentUserId) {
+    this._notifyPersonal(newState);
+    return;
+  }
+
+  // AC-4/5: Verbosity gate for non-personal notifications
+  const verbosity = this._adapter.settings.get('notificationVerbosity') ?? 'all';
+  if (verbosity === 'silent') return;
+  if (verbosity === 'gm-only' && !this._adapter.users.isGM()) return;
+
+  this._enqueue(userId, newState, previousState);
+}
+```
+
+### Coalescing Timer — 3-Second Window
+
+**Canonical timer value: 3000ms** (driven by epics ACs — "within 3 seconds").
+
+⚠️ Architecture data flow diagram says "300ms coalesce window" — this is inconsistent with the AC. **Epic ACs are canonical; use 3000ms.**
+
+```js
+_enqueue(userId, newState, prevState) {
+  const existing = this.#coalesceMap.get(userId);
+  if (existing) {
+    clearTimeout(existing.timer);            // reset window on each new change
+    existing.lastState = newState;
+    existing.changeCount += 1;
+  } else {
+    this.#coalesceMap.set(userId, { timer: null, prevState, lastState: newState, changeCount: 1 });
+  }
+  const entry = this.#coalesceMap.get(userId);
+  entry.timer = setTimeout(() => this._flush(userId), 3_000);
+}
+
+_flush(userId) {
+  const entry = this.#coalesceMap.get(userId);
+  if (!entry) return;
+  this.#coalesceMap.delete(userId);
+
+  // AC-3: Net-zero suppression — no notification if final state equals original
+  if (entry.lastState === entry.prevState) return;
+
+  const name = this._adapter.users.get(userId)?.name ?? userId;
+  const isHidden = entry.lastState === 'hidden';
+  const msg = isHidden
+    ? `GM hid ${name}'s camera`
+    : `GM showed ${name}'s camera`;
+
+  this._adapter.notifications.info(msg);
+}
+```
+
+### Personal Notification Messages (AC-2)
+
+```js
+_notifyPersonal(newState) {
+  const msg = newState === 'hidden'
+    ? "GM has hidden your camera. Your portrait is shown to other Participants."
+    : "Your camera is now visible to the table.";
+  this._adapter.notifications.info(msg);
+}
+```
+
+Note: personal notification fires immediately (no coalescing). The `currentUserId` guard in `_onStateChanged` ensures coalescing loop is NOT entered for personal events.
+
+### module.js Init Order Extension
+
+```js
+// Hooks.once('ready') — existing wiring ends at visibilityBadge.init()
+// Add:
+notificationBus = new NotificationBus(adapter);
+notificationBus.init();
+// Story 2.2: DirectorsBoard (lazy, GM only)
+```
+
+NotificationBus runs for **all clients** (GM and players) because:
+- GM sees general notifications about all participants
+- Players see personal notifications about themselves
+
+The verbosity setting filters which general notifications each client sees.
+
+### Vitest Fake Timer Pattern (CRITICAL — from Story 1.6)
+
+The coalescing timer is 3000ms. Use `vi.useFakeTimers()` for all timer-related tests.
+
+⚠️ **Two-step advance rule:** If a timer callback schedules another timer (or if `clearTimeout` + new `setTimeout` happens inside the callback), you need two separate `vi.advanceTimersByTime()` calls:
+
+```js
+import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';
+
+describe('NotificationBus coalescing', () => {
+  beforeEach(() => vi.useFakeTimers());
+  afterEach(() => vi.useRealTimers());
+
+  it('fires single notification after 3s coalescing window', () => {
+    // ... setup bus + mocks ...
+    bus._onStateChanged({ userId: 'u1', newState: 'hidden', previousState: 'active' });
+    bus._onStateChanged({ userId: 'u1', newState: 'active', previousState: 'hidden' }); // resets timer
+    vi.advanceTimersByTime(3_001);
+    // net-zero: 'active' === 'active' → no notification
+    expect(notifMock.info).not.toHaveBeenCalled();
+  });
+
+  it('flushes with correct message after window expires', () => {
+    bus._onStateChanged({ userId: 'u1', newState: 'hidden', previousState: 'active' });
+    vi.advanceTimersByTime(3_001);
+    expect(notifMock.info).toHaveBeenCalledWith("GM hid Player's camera");
+  });
+});
+```
+
+For nested timer tests (clearTimeout + new setTimeout in rapid succession):
+```js
+vi.advanceTimersByTime(1_500); // mid-window: timer reset by second event
+// fire second event
+vi.advanceTimersByTime(3_001); // fires the second timer
+```
+
+### FoundryAdapter.notifications Surface (Already Implemented)
+
+```js
+// From src/foundry/FoundryAdapter.js (Story 1.3) — reuse as-is:
+adapter.notifications.info(msg)
+adapter.notifications.warn(msg)
+adapter.notifications.error(msg)
+```
+
+Do NOT call `ui.notifications.info()` directly. Always go through `adapter.notifications.*`.
+
+### FoundryAdapter.settings — `client` Setting Scope
+
+`adapter.settings.register()` already delegates to `game.settings.register()` with the provided config. Passing `scope: 'client'` is sufficient — the adapter doesn't transform this value.
+
+`adapter.settings.get('notificationVerbosity')` returns the current user's client preference.
+
+### Deferred Debt Cleanup (Task 4)
+
+These are carry-over from `deferred-work.md` — fold in during this story:
+
+**4.1 — `_revisions` Map leak (ScryingPoolController.js:31):**
+```js
+// Add cleanupUser(userId) public method:
+cleanupUser(userId) {
+  this._revisions.delete(userId);
+  this._pendingOps.delete(userId);
+}
+```
+Wire this into a `Hooks.on('deleteUser', ...)` handler in `init()` or expose for external call.
+
+**4.2/4.3 — Listener cleanup:**
+```js
+// ScryingPoolController.init():
+this._echoHookId = Hooks.on('scrying-pool:echoReceived', ...)  // store id
+// ScryingPoolController.teardown():
+Hooks.off('scrying-pool:echoReceived', this._echoHookId);
+```
+Same pattern for VisibilityManager.
+
+**4.4 — Echo revision validation:**
+```js
+// Before using revision in _onEcho():
+if (!Number.isFinite(revision)) {
+  console.warn('[ScryingPool] _onEcho: invalid revision', revision);
+  return;
+}
+```
+
+### `scrying-pool:stateChanged` Payload Shape
+
+Emitted by `StateStore` (verified from Story 1.3 implementation):
+```js
+Hooks.callAll('scrying-pool:stateChanged', {
+  userId,        // string — affected participant ID
+  newState,      // string — one of VISIBILITY_STATES
+  previousState, // string — state before the change
+  revision,      // number — monotonic revision counter
+  source,        // string — 'gm' | 'preset' | 'hydration'
+});
+```
+
+NotificationBus needs: `userId`, `newState`, `previousState`.
+
+### Project Structure Notes
+
+**New files:**
+```
+src/notifications/NotificationBus.js           ← NEW
+tests/unit/notifications/NotificationBus.test.js  ← NEW
+```
+
+**Modified files:**
+```
+module.js                                      ← import + notificationVerbosity setting + wiring
+lang/en.json                                   ← notification i18n keys
+styles/components/_notification.less           ← replace stub if custom toast styles needed
+src/core/ScryingPoolController.js              ← deferred debt: cleanup methods
+src/core/VisibilityManager.js                  ← deferred debt: listener cleanup
+```
+
+**Do NOT modify:**
+- `src/foundry/FoundryAdapter.js` — notifications surface is complete from Story 1.3
+- `src/core/StateStore.js` — event emission is complete
+- `src/ui/shared/AVTileAdapter.js` — no changes needed

+## Dev Agent Record
+
+### Agent Model Used
+
+Claude Sonnet 4.6 (claude-sonnet-4.6)
+
+### Debug Log References
+
+- Net-zero suppression test gotcha: `active→hidden→active` is suppressed (net-zero); fixed by using `active→hidden→self-muted` as second state so prevState ≠ lastState at flush time.
+- `_coalesceMap` uses convention-private underscore (not `#` hard private) so tests can inspect `.size`.
+- ESLint `no-undef` eslint-disable directives in `NotificationBus.js` were removed — `Hooks` is already a declared global in the ESLint config.
+- Deferred debt 4.4 (`Number.isFinite` validation) was already implemented in `_onEcho()`; no code change needed.
+
+### Completion Notes List
+
+- NotificationBus: 28 tests, all passing. Coalescing, verbosity, personal notifications, net-zero suppression, teardown all implemented and tested.
+- Deferred debt 4.1–4.3 resolved: ScryingPoolController now stores `_echoHandler` + `_disconnectHookId`, exposes `teardown()`, wires `userConnected` cleanup. VisibilityManager now stores `_stateChangedHookId`, exposes `teardown()`.
+- `styles/components/_notification.less` updated with `.scrying-pool` scope placeholder — native `ui.notifications` toasts need no custom CSS.
+- Total: 335 tests passing (296 baseline + 28 NotificationBus + 11 teardown/disconnect).
+
+### File List
+
+- `src/notifications/NotificationBus.js` — NEW
+- `tests/unit/notifications/NotificationBus.test.js` — NEW
+- `module.js` — NotificationBus import, setting registration, init wiring
+- `lang/en.json` — notification messages + notificationVerbosity setting keys
+- `styles/components/_notification.less` — minimal `.scrying-pool` scope placeholder
+- `src/core/ScryingPoolController.js` — `_echoHandler` + `_disconnectHookId`, `teardown()`, `userConnected` cleanup in `init()`
+- `src/core/VisibilityManager.js` — `_stateChangedHookId` stored in `init()`, `teardown()` added
+- `tests/unit/core/ScryingPoolController.test.js` — teardown + disconnect cleanup tests
+- `tests/unit/core/VisibilityManager.test.js` — teardown tests

+
+### Review Findings
+
+#### Decision Needed
+
+- [x] [Review][Decision] Hardcoded notification strings bypass i18n system — **RESOLVED: Add i18n support now** — NotificationBus.js uses raw strings instead of `game.i18n.localize()`. Will extend FoundryAdapter with i18n surface and update NotificationBus to use localization.
+
+#### Patches Required
+
+- [x] [Review][Patch] Add i18n support to FoundryAdapter and NotificationBus [FoundryAdapter.js, NotificationBus.js, lang/en.json] — Extend FoundryAdapter with i18n surface, update NotificationBus to use `game.i18n.localize()` for all notification messages. Use existing lang/en.json keys.
+- [x] [Review][Patch] Property name mismatch: `state` vs `newState` breaks all notifications [NotificationBus.js:68, StateStore.js:105] — Fixed destructuring to use `state` property emitted by StateStore.
+- [x] [Review][Patch] Unused `changeCount` property (dead code) [NotificationBus.js] — Now used in message output to show change count.
+- [x] [Review][Patch] Coalesced notification omits change count from message [NotificationBus.js:137-139] — Change count now appended to notification message (e.g., "(3 changes)").
+- [x] [Review][Patch] No cleanup of coalesceMap entries for disconnected users [NotificationBus.js] — Added userConnected hook listener to clean up entries on disconnect.
+- [x] [Review][Patch] Race condition: timer fires after teardown [NotificationBus.js:132-134] — Added null check for entry in _flush to prevent TypeError.
+- [x] [Review][Patch] No validation of `notificationVerbosity` setting value [NotificationBus.js:85] — Added validation with fallback to 'all' for invalid values.
+- [x] [Review][Patch] `_flush` missing null check for entry [NotificationBus.js:132-134] — Added guard to return early if entry is undefined.
+- [x] [Review][Patch] No input validation for `newState`/`previousState` [NotificationBus.js:107-123] — Added type checks in _enqueue to reject invalid parameters.
+- [x] [Review][Patch] Stale closure in coalescing timers [NotificationBus.js:124-128] — Added additional null check for entry.timer to mitigate stale closure issues.
+- [x] [Review][Patch] No protection against rapid init/teardown cycles [NotificationBus.js:42-57] — Added guard in init() to prevent multiple initializations without teardown.
+
+#### Deferred (Pre-existing / Out of Scope)
+
+- [x] [Review][Defer] VisibilityManager only handles binary states [VisibilityManager.js:84-90] — T-09 handles hidden/offline/cam-lost/ghost as "disable", else as "enable". States like self-muted, reconnecting fall through incorrectly. Pre-existing issue, not introduced in this story.
+- [x] [Review][Defer] No handling of `setMatrix` hook events [NotificationBus.js] — setMatrix emits without userId; bulk state changes won't trigger notifications. Pre-existing architectural limitation.

+# Story 2.2: Director's Board — Core Layout & Participant Toggle
+
+Status: done
+
+## Story
+
+As a **GM**,
+I want a dedicated floating board showing all participants in a seating-chart layout with per-participant visibility toggle,
+so that I can manage all camera states at a glance without right-clicking individual AV tiles.
+
+## Acceptance Criteria
+
+1. **Given** the module is active and the user is GM
+   **When** the GM presses `Ctrl+Shift+V` or clicks the dedicated sidebar button
+   **Then** the Director's Board opens as a resizable, draggable `ApplicationV2` window
+
+2. **Given** the Director's Board is open
+   **When** it renders
+   **Then** every connected participant has a `ParticipantCard` (80×100px: 48px avatar + `StateRing` + name 12px 2-line truncate + hover toggle-icon overlay)
+   **And** cards are laid out in a CSS grid: `auto-fill, minmax(80px, 1fr)`
+
+3. **Given** a participant's state changes
+   **When** the socket broadcast completes
+   **Then** the Director's Board updates that participant's card within 500ms
+   **And** the board is a dumb view — subscribes to `scrying-pool:stateChanged` Hook with no local state cache
+
+4. **Given** the GM clicks a participant card
+   **When** the click is processed
+   **Then** the participant's visibility toggles between `active` and `hidden`
+   **And** the behaviour and persistence match FR-1 (same as AV tile right-click — goes through `controller.action()`)
+
+5. **Given** the GM uses keyboard navigation
+   **When** arrow keys are pressed in the board
+   **Then** focus moves between participant cards
+   **And** `Space` or `Enter` toggles the focused participant's visibility
+
+6. **Given** `Ctrl+Shift+V` is pressed while the board is already open
+   **When** the event fires
+   **Then** the board closes (singleton toggle behaviour)
+
+7. **Given** the user is not GM
+   **When** they attempt to open the Director's Board
+   **Then** the sidebar button is not shown and the keyboard shortcut has no effect
+
+8. **Given** a screen reader user navigates to a `ParticipantCard`
+   **When** focus lands
+   **Then** `role="listitem"`, `aria-label="[Name] — [state label]"` is announced
+   **And** the hover toggle icon is independently keyboard-focusable with `role="button"` and a descriptive `aria-label` ("Hide [Name] from table" or "Show [Name] to table")
+
+## Tasks / Subtasks
+
+- [x] Task 1: Create `src/ui/shared/ParticipantCard.js` (AC: 2, 3, 4, 5, 8)
+  - [x] 1.1: Write failing tests in `tests/unit/ui/shared/ParticipantCard.test.js` (TDD red) — test `buildCardContext()` and `resolveToggleTarget()`
+  - [x] 1.2: Export `function buildCardContext(userId, stateStore, controller, adapter)` — returns `{ userId, name, avatarSrc, state, stateLabel, hasPendingOp, isHidden, toggleAriaLabel, cardAriaLabel }` (no side effects)
+  - [x] 1.3: Export `function resolveToggleTarget(currentState)` — returns `'hidden'` when `currentState !== 'hidden'`, else `'active'`
+  - [x] 1.4: Export `function buildBoardContext(stateStore, controller, adapter)` — calls `adapter.users.all()`, maps each user id through `buildCardContext()`, returns `{ participants, isEmpty }`
+  - [x] 1.5: Green all ParticipantCard tests
+
+- [x] Task 2: Create `src/ui/gm/DirectorsBoard.js` (AC: 1, 2, 3, 4, 5, 6, 7, 8)
+  - [x] 2.1: Write failing tests in `tests/unit/ui/gm/DirectorsBoard.test.js` (TDD red)
+  - [x] 2.2: Implement conditional base-class pattern for test compatibility (see Dev Notes → ApplicationV2 Conditional Pattern)
+  - [x] 2.3: Implement `static DEFAULT_OPTIONS` and `static PARTS` (one part: `board`)
+  - [x] 2.4: Implement `async _prepareContext(options)` — calls `buildBoardContext(stateStore, controller, adapter)`; reads position from GM User flag; returns context
+  - [x] 2.5: Implement event delegation: single `click` listener on app root dispatching via `data-action="toggle-participant"` and `data-user-id`; call `_dispatchToggle(userId)`
+  - [x] 2.6: Implement keyboard navigation: `keydown` listener on board root; `ArrowLeft/Right/Up/Down` moves focus between `[data-user-id]` cards; `Space/Enter` dispatches toggle on focused card
+  - [x] 2.7: Implement `_dispatchToggle(userId)` — reads current state from `stateStore.getState(userId)`, resolves `resolveToggleTarget(state)`, calls `controller.action({ userId, targetState })`
+  - [x] 2.8: Implement `_onStateChanged(data)` — hook handler; calls `this.render({ force: true })` if board is rendered
+  - [x] 2.9: Implement `init()` — registers `Hooks.on('scrying-pool:stateChanged', ...)`, stores `_hookId`
+  - [x] 2.10: Implement `teardown()` — `Hooks.off('scrying-pool:stateChanged', this._hookId)`, `this._hookId = null`
+  - [x] 2.11: Implement position persistence: on `_onClose()` and `_onPosition()`, save `{left, top, width, height, open}` to `game.user.setFlag('video-view-manager', 'directorsBoardState', ...)`
+  - [x] 2.12: Implement `toggle()` public method — if `this.rendered` → `this.close()`; else → `this.render({ force: true })`
+  - [x] 2.13: Green all DirectorsBoard tests
+
+- [x] Task 3: Complete `templates/directors-board.hbs` (AC: 2, 5, 8)
+  - [x] 3.1: Replace stub with full board layout: `<section class="scrying-pool directors-board" role="list" aria-label="Director's Board">` wrapping cards grid
+  - [x] 3.2: Render each participant via `{{> participant-card}}` partial (or inline using card context)
+  - [x] 3.3: Add empty state: `{{#unless participants.length}}<p class="directors-board__empty">...</p>{{/unless}}`
+  - [x] 3.4: Add footer stub for future Preset actions (disabled): `<footer class="directors-board__footer"><button disabled>Save Preset…</button><button disabled>Load Preset…</button></footer>`
+
+- [x] Task 4: Complete `templates/participant-card.hbs` (AC: 2, 8)
+  - [x] 4.1: Replace stub with: `<div class="scrying-pool participant-card sp-state-{{state}}{{#if hasPendingOp}} sp-state-pending{{/if}}" role="listitem" aria-label="{{cardAriaLabel}}" data-user-id="{{userId}}" tabindex="0">`
+  - [x] 4.2: Add avatar: `<div class="participant-card__avatar"><img src="{{avatarSrc}}" alt="{{name}}"></div>`
+  - [x] 4.3: Add name: `<p class="participant-card__name">{{name}}</p>`
+  - [x] 4.4: Add toggle button overlay: `<button class="participant-card__toggle" data-action="toggle-participant" data-user-id="{{userId}}" role="button" aria-label="{{toggleAriaLabel}}" tabindex="-1"><i class="fas {{#if isHidden}}fa-eye{{else}}fa-eye-slash{{/if}}" aria-hidden="true"></i></button>`
+
+- [x] Task 5: Style `styles/components/_participant-card.less` and `_directors-board.less` (AC: 2)
+  - [x] 5.1: `_participant-card.less` — card 80×100px, avatar 48px, 12px name with 2-line truncate, hover reveals toggle overlay; `sp-state-*` classes apply border ring color+shape per token system; `sp-state-pending` uses spinner icon
+  - [x] 5.2: `_directors-board.less` — CSS grid `display: grid; grid-template-columns: repeat(auto-fill, minmax(80px, 1fr)); gap: 8px;`; board scoped to `.scrying-pool.directors-board`; footer layout; empty-state styles
+
+- [x] Task 6: Wire keyboard shortcut + sidebar button in `module.js` (AC: 1, 6, 7)
+  - [x] 6.1: Import `DirectorsBoard` in `module.js`
+  - [x] 6.2: In `Hooks.once('init')`: register keybinding `scrying-pool.openDirectorsBoard` (`Ctrl+Shift+V`, `restricted: true`, singleton-guarded via `if (adapter.users.isGM())`)
+  - [x] 6.3: In `Hooks.once('init')`: register `Hooks.on('getSceneControlButtons', controls => { ... })` to inject GM-only sidebar icon (see Dev Notes)
+  - [x] 6.4: In `Hooks.once('ready')`, after `notificationBus.init()`: `if (adapter.users.isGM()) { directorsBoard = new DirectorsBoard(stateStore, scryingPoolController, adapter); directorsBoard.init(); }`
+  - [x] 6.5: Keyboard shortcut callback calls `directorsBoard?.toggle()` — no-op if `directorsBoard` is null
+
+- [x] Task 7: Add i18n keys in `lang/en.json` (AC: 1, 2, 8)
+  - [x] 7.1: Add `video-view-manager.directorsBoard.title` = `"Director's Board"`
+  - [x] 7.2: Add `video-view-manager.directorsBoard.empty` = `"No participants connected."`
+  - [x] 7.3: Add `video-view-manager.directorsBoard.openButton` = `"Open Director's Board"`
+  - [x] 7.4: Add `video-view-manager.directorsBoard.footer.savePreset` = `"Save Preset…"`
+  - [x] 7.5: Add `video-view-manager.directorsBoard.footer.loadPreset` = `"Load Preset…"`
+
+- [x] Task 8: Pipeline verification
+  - [x] 8.1: `npm run lint` exits 0 for all modified files
+  - [x] 8.2: `npm run test` exits 0 — expected: 335 baseline + new DirectorsBoard + ParticipantCard tests

+## Dev Notes
+
+### New File Locations
+
+```
+src/ui/gm/DirectorsBoard.js             ← NEW (same directory as ScryingPoolStrip.js)
+src/ui/shared/ParticipantCard.js        ← NEW (same directory as AVTileAdapter.js)
+tests/unit/ui/gm/DirectorsBoard.test.js ← NEW
+tests/unit/ui/shared/ParticipantCard.test.js ← NEW
+```
+
+### Import Boundary (Hard Rule — ESLint-enforced)
+
+```
+src/ui/ → may import: src/core/, src/contracts/, src/utils/ ONLY
+```
+
+❌ Do NOT import from `src/foundry/`, `src/notifications/`, or `src/presets/` inside `src/ui/`.
+ESLint `import/no-restricted-paths` will catch violations at lint time.
+
+### ApplicationV2 Conditional Pattern for Test Compatibility
+
+The project does NOT have ApplicationV2 available in the test environment. Use the same conditional-base-class pattern as `ScryingPoolStrip.js`:
+
+```js
+// @ts-nocheck
+/* global foundry */
+import { buildBoardContext, resolveToggleTarget } from '../shared/ParticipantCard.js';
+
+// Conditional base class — test environment lacks foundry globals
+const _AppBase =
+  typeof foundry !== 'undefined' &&
+  foundry.applications?.api?.HandlebarsApplicationMixin &&
+  foundry.applications?.api?.ApplicationV2
+    ? foundry.applications.api.HandlebarsApplicationMixin(
+        foundry.applications.api.ApplicationV2
+      )
+    : class _FallbackApp {
+        static DEFAULT_OPTIONS = {};
+        static PARTS = {};
+        get rendered() { return false; }
+        async render(_opts) {}
+        async close(_opts) {}
+        async _prepareContext(_opts) { return {}; }
+      };
+
+export class DirectorsBoard extends _AppBase {
+  static DEFAULT_OPTIONS = {
+    id: 'scrying-pool-directors-board',
+    classes: ['scrying-pool', 'directors-board'],
+    window: { title: "Director's Board", resizable: true },
+    position: { width: 400, height: 300 },
+  };
+
+  static PARTS = {
+    board: {
+      template: 'modules/video-view-manager/templates/directors-board.hbs',
+    },
+  };
+
+  constructor(stateStore, controller, adapter, options = {}) {
+    super(options);
+    this._stateStore = stateStore;
+    this._controller = controller;
+    this._adapter = adapter;
+    this._hookId = null;
+  }
+  // ...
+}
+```
+
+### ApplicationV2 API Differences from Application
+
+| `Application` (old — ScryingPoolStrip) | `ApplicationV2` (new — DirectorsBoard) |
+|---|---|
+| `static get defaultOptions()` | `static DEFAULT_OPTIONS = {}` |
+| `defaultOptions.template` | `static PARTS = { key: { template: '...' } }` |
+| `getData()` | `async _prepareContext(options)` |
+| `activateListeners(html)` | Event delegation on app root (do NOT add per-child listeners) |
+| `this.render(true)` | `this.render({ force: true })` |
+| `super.defaultOptions` merge | No super merge needed — set directly in DEFAULT_OPTIONS |
+
+⚠️ **Critical:** ApplicationV2 rerenders replace inner DOM. Never attach event listeners to child nodes inside `PARTS` templates. Use event delegation on the application root element (`.element` or the outermost container) in `_onRender()`.
+
+### Event Delegation Pattern
+
+```js
+// Override in DirectorsBoard:
+_onRender(context, options) {
+  super._onRender?.(context, options);
+  const root = this.element;  // ApplicationV2: this.element is the outermost DOM node
+
+  // Single delegated listener — survives re-renders because root persists
+  root.addEventListener('click', (e) => {
+    const btn = e.target.closest('[data-action="toggle-participant"]');
+    if (!btn) return;
+    e.stopPropagation();
+    this._dispatchToggle(btn.dataset.userId);
+  });
+
+  // Keyboard navigation on the cards list
+  const list = root.querySelector('[role="list"]');
+  list?.addEventListener('keydown', (e) => this._onKeydown(e));
+}
+```
+
+### Keyboard Navigation Implementation
+
+```js
+_onKeydown(e) {
+  const cards = [...this.element.querySelectorAll('[data-user-id]')];
+  const current = document.activeElement;
+  const idx = cards.indexOf(current);
+
+  if (e.key === 'ArrowRight' || e.key === 'ArrowDown') {
+    e.preventDefault();
+    cards[(idx + 1) % cards.length]?.focus();
+  } else if (e.key === 'ArrowLeft' || e.key === 'ArrowUp') {
+    e.preventDefault();
+    cards[(idx - 1 + cards.length) % cards.length]?.focus();
+  } else if (e.key === 'Enter' || e.key === ' ') {
+    e.preventDefault();
+    if (current?.dataset?.userId) this._dispatchToggle(current.dataset.userId);
+  }
+}
+```
+
+### Toggle Dispatch — Must Match FR-1 Behaviour
+
+Use `controller.action()` exactly as `ScryingPoolStrip._dispatchAction()` does:
+
+```js
+_dispatchToggle(userId) {
+  if (!userId) return;
+  const currentState = this._stateStore.getState(userId) ?? 'active';
+  const targetState = resolveToggleTarget(currentState);
+  // Pending op guard (same pattern as ScryingPoolStrip)
+  if (this._controller.hasPendingOp?.(userId)) return;
+  this._controller.action({ userId, targetState });
+}
+```
+
+⚠️ Do NOT call `stateStore.setState()` or `adapter.socket.emit()` directly. Always go through `controller.action()`.
+
+### Dumb View Rule (AC-3)
+
+DirectorsBoard reads state on every render. No local state cache:
+
+```js
+async _prepareContext(options) {
+  return buildBoardContext(this._stateStore, this._controller, this._adapter);
+}
+```
+
+`buildBoardContext()` calls `this._stateStore.getState(userId)` fresh each time.
+
+### State Update ≤500ms (AC-3)
+
+`_onStateChanged(data)` must call `this.render({ force: true })`. The socket broadcast → `StateStore` update → `Hooks.callAll('scrying-pool:stateChanged')` pipeline is already sub-100ms. Re-rendering on every hook event is correct and sufficient.
+
+### Singleton Guard + Position Persistence
+
+```js
+// In module.js Hooks.once('ready'):
+directorsBoard = new DirectorsBoard(stateStore, scryingPoolController, adapter);
+directorsBoard.init();
+
+// Keyboard shortcut callback (Hooks.once('init')):
+game.keybindings.register('scrying-pool', 'openDirectorsBoard', {
+  name: 'Open/Close Director\'s Board',
+  hint: 'Toggles the Director\'s Board window',
+  editable: [{ key: 'KeyV', modifiers: ['Control', 'Shift'] }],
+  restricted: true,  // GM only
+  onDown: () => directorsBoard?.toggle(),
+});
+```
+
+Position saved to GM User flag `'video-view-manager', 'directorsBoardState'` as `{left, top, width, height, open}` — same flag namespace pattern as `stripState`.
+
+### Sidebar Button — `getSceneControlButtons` Hook
+
+```js
+// Hooks.once('init') in module.js:
+Hooks.on('getSceneControlButtons', (controls) => {
+  if (!game.user?.isGM) return;
+  const avControls = controls.find(c => c.name === 'token'); // or 'lighting'
+  // Add to the tools of an existing group, or append a standalone button
+  // The exact hook signature changed in v12+; use the 'notes' or 'basic' group as fallback
+  // See Dev Notes → Sidebar Button Approach
+});
+```
+
+⚠️ **Sidebar button implementation note:** Foundry v14's `getSceneControlButtons` hook provides an array of control groups. The safest approach is to add a tool button to the existing AV/token controls group rather than creating a new top-level group. The exact API depends on the Foundry v14 hook signature. Research during implementation with `Hooks.once('ready', () => console.log(ui.controls?.controls))` to inspect available control groups. If the hook API is uncertain, fall back to a simple `<button>` rendered inside the `ScryingPoolStrip` footer with CTA "Open Director's Board ↗" (the UX spec mentions this as the strip footer CTA, which avoids the sidebar API entirely).
+
+### Canonical Action Labels (Reuse from ScryingPoolStrip)
+
+```js
+// Import from ScryingPoolStrip to avoid duplication:
+import { LABELS, resolveTargetState } from './ScryingPoolStrip.js';
+// Or: re-export the same constants from ParticipantCard.js as the canonical source for card-specific labels
+```
+
+⚠️ UX-DR21: "Hide from table" and "Show to table" verbatim. Same string constants as ScryingPoolStrip, never synonyms. The `toggleAriaLabel` in `buildCardContext` should return:
+- `"Hide {name} from table"` when visible
+- `"Show {name} to table"` when hidden
+
+### `buildCardContext()` Reference Implementation
+
+```js
+export function buildCardContext(userId, stateStore, controller, adapter) {
+  const user = adapter.users.get(userId) ?? { name: userId, avatar: null };
+  const state = stateStore.getState(userId) ?? 'active';
+  const isHidden = state === 'hidden';
+  const name = user.name ?? userId;
+  return {
+    userId,
+    name,
+    avatarSrc: user.avatar ?? 'icons/svg/mystery-man.svg',
+    state,
+    stateLabel: _stateLabel(state),
+    hasPendingOp: controller.hasPendingOp?.(userId) ?? false,
+    isHidden,
+    cardAriaLabel: `${name} — ${_stateLabel(state)}`,
+    toggleAriaLabel: isHidden ? `Show ${name} to table` : `Hide ${name} from table`,
+  };
+}
+
+export function buildBoardContext(stateStore, controller, adapter) {
+  const userIds = adapter.users.all?.() ?? [];
+  const participants = userIds.map(u => buildCardContext(u.id ?? u, stateStore, controller, adapter));
+  return { participants, isEmpty: participants.length === 0 };
+}
+```
+
+The `_stateLabel()` function already exists in `ScryingPoolStrip.js` — copy the same implementation (same 8 states + same labels). Do NOT import it from ScryingPoolStrip (import boundary: both are in `src/ui/` which is fine, but keeping utility functions co-located in `ParticipantCard.js` is cleaner).
+
+### CSS Token Rules (No Exceptions)
+
+```less
+// styles/components/_participant-card.less
+// All selectors MUST be under .scrying-pool
+// Use --sp-* tokens only — no --color-*, --font-*, --border-* Foundry tokens directly
+
+.scrying-pool .participant-card {
+  width: 80px;
+  height: 100px;
+  position: relative;
+  border: 2px solid var(--sp-border);
+  border-radius: 4px;
+  cursor: pointer;
+
+  // State ring — border color and shape driven by sp-state-* tokens
+  &.sp-state-hidden { border-color: var(--sp-state-hidden-border); border-style: dashed; }
+  &.sp-state-active { border-color: var(--sp-state-active-border); border-style: solid; }
+  // ... all 9 states
+
+  &__avatar {
+    width: 48px;
+    height: 48px;
+    margin: 8px auto 4px;
+    display: block;
+    border-radius: 50%;
+    object-fit: cover;
+  }
+
+  &__name {
+    font-size: 12px;
+    text-align: center;
+    overflow: hidden;
+    display: -webkit-box;
+    -webkit-line-clamp: 2;
+    -webkit-box-orient: vertical;
+    padding: 0 4px;
+    color: var(--sp-text-primary);
+  }
+
+  &__toggle {
+    position: absolute;
+    inset: 0;
+    opacity: 0;
+    display: flex;
+    align-items: center;
+    justify-content: center;
+    background: var(--sp-surface);
+    transition: opacity var(--sp-fade-hide);
+
+    &:focus { opacity: 1; }  // always visible for keyboard users
+  }
+
+  &:hover &__toggle,
+  &:focus-within &__toggle { opacity: 1; }
+
+  &:focus { @include sp-focus-ring(); }
+}
+```
+
+### Focus Ring — Module-Wide Pattern
+
+From `styles/tokens/_focus.less` — do NOT reimplement. Import via `@import` in `_participant-card.less` if needed, or rely on the module-wide focus ring already applied globally under `.scrying-pool`.
+
+### Second-Signal Rule (Accessibility Mandatory)
+
+Every state must signal: **color + icon + shape** (NFR-5, UX-DR13). The `sp-state-*` class provides all three when `_states.less` tokens are applied. Cards get state via `class="... sp-state-{{state}}"`.
+
+### i18n Compliance
+
+All user-visible strings must use `adapter.i18n.localize()` in JS. In Handlebars templates, use `{{localize "video-view-manager.directorsBoard.title"}}`. Do NOT hardcode English strings in templates.
+
+Exception: aria-labels built in `buildCardContext()` may interpolate user names directly (names are data, not UI copy).
+
+### Module.js Init Order Extension
+
+After Story 2.2, `module.js` `Hooks.once('ready')` sequence becomes:
+
+```js
+// ... (existing, unchanged) ...
+notificationBus = new NotificationBus(adapter);
+notificationBus.init();
+// Story 2.2: DirectorsBoard (lazy, GM only)
+if (adapter.users.isGM()) {
+  directorsBoard = new DirectorsBoard(stateStore, scryingPoolController, adapter);
+  directorsBoard.init();
+}
+```
+
+Also add `let directorsBoard;` at module scope (line ~39, after `let notificationBus;`).
+
+Keybinding registration goes in `Hooks.once('init')`, before adapter construction:
+
+```js
+// At the end of Hooks.once('init'), after adapter construction and settings registration:
+if (game.user?.isGM) {
+  game.keybindings.register('scrying-pool', 'openDirectorsBoard', {
+    name: "Open/Close Director's Board",
+    hint: "Toggles the Director's Board window",
+    editable: [{ key: 'KeyV', modifiers: ['Control', 'Shift'] }],
+    restricted: true,
+    onDown: () => directorsBoard?.toggle(),
+  });
+}
+```
+

+  });
+});
+```
+
+⚠️ **Test environment note:** `Hooks` is a FoundryVTT global. Tests that call `init()` or `teardown()` need to set/delete `global.Hooks` as a stub. Use `beforeEach`/`afterEach` to set up and clean up. The `createFoundryAdapterMock()` mock provides an `adapter.hooks` surface, but `DirectorsBoard` uses `Hooks.*` globals directly (same pattern as `NotificationBus`).

+### Deferred Debt Status
+
+All high-priority deferred items from Epic 1 retro were folded into Story 2.1 (Tasks 4.1–4.4):
+- `_revisions` Map leak ✅ fixed in 2.1
+- ScryingPoolController listener cleanup ✅ fixed in 2.1
+- VisibilityManager listener cleanup ✅ fixed in 2.1
+- Echo revision NaN/Infinity validation ✅ fixed in 2.1
+
+Remaining deferred items in `deferred-work.md` (post-2.1 code review) are pre-existing architectural limitations NOT targeted for Story 2.2:
+- VisibilityManager binary state handling (T-09 edge case)
+- No `setMatrix` hook handling in NotificationBus
+- ScryingPoolController cleanup limited to `userConnected` hook

+## Dev Agent Record
+
+### Agent Model Used
+
+Claude Sonnet 4.6 (claude-sonnet-4.6)
+
+### Debug Log References
+
+No blockers encountered. Sidebar button implementation uses the `getSceneControlButtons` hook, appending to the token group's tools array. Since the exact Foundry v14 hook API was uncertain, the implementation uses optional chaining (`controls.find?.()`) and `tokenGroup?.tools`) to be safe — gracefully no-ops if the hook API differs. The keyboard shortcut and `ready` hook wiring are the primary open path.
+
+### Completion Notes List
+
+- ✅ **Task 1** (ParticipantCard.js): 26 tests. Pure utility exports `buildCardContext()`, `buildBoardContext()`, `resolveToggleTarget()`. No side effects. All 8 state labels canonical.
+- ✅ **Task 2** (DirectorsBoard.js): 22 tests. ApplicationV2 conditional base-class pattern (same as ScryingPoolStrip for Application). Constructor side-effect-free. `init()`/`teardown()` manage hook lifecycle. `_dispatchToggle()` goes through `controller.action()` (FR-1 compliant, pending-op guarded). Event delegation on app root in `_onRender()`. Keyboard nav (arrow keys + Space/Enter). Position persistence via GM user flag.
+- ✅ **Task 3** (directors-board.hbs): Full layout with `[role="list"]` section, Handlebars `{{> partial}}` for cards, empty state, disabled footer preset buttons.
+- ✅ **Task 4** (participant-card.hbs): `[role="listitem"]`, `aria-label="{{cardAriaLabel}}"`, `data-user-id`, `tabindex="0"`, avatar, name (2-line truncate), toggle overlay button with independent `tabindex="-1"`.
+- ✅ **Task 5** (Less styles): `_participant-card.less` — 80×100px, 48px avatar, all 9 sp-state-* variants with correct ring shapes per second-signal rule, hover/focus overlay, reduced motion guard. `_directors-board.less` — `auto-fill minmax(80px, 1fr)` grid, empty state, footer.
+- ✅ **Task 6** (module.js wiring): Import, `let directorsBoard`, keybinding `Ctrl+Shift+V` (`restricted: true`), `getSceneControlButtons` hook (safe optional chaining), ready hook construction + `directorsBoard.init()`.
+- ✅ **Task 7** (i18n): 5 keys added under `video-view-manager.directorsBoard.*`.
+- ✅ **Task 8** (pipeline): `npm run lint` exits 0 (no new errors). `npm run test` exits 0 — **383 tests passing** (335 baseline + 26 ParticipantCard + 22 DirectorsBoard).

+### Review Findings
+
+#### Decision Needed
+- [x] [Review][Dismiss] Missing StateRing Component — **DISMISSED**: Border styling via `sp-state-*` CSS classes on the card provides the StateRing functionality (color + shape signals per second-signal rule). The spec's mention of "StateRing" is satisfied by the border styling implementation.
+
+#### Patch
+- [x] [Review][Patch] Implement Sidebar Button Fallback in ScryingPoolStrip — Added CTA button in `roster-strip.hbs` with event listener in `ScryingPoolStrip.js` activateListeners. Provides fallback when `getSceneControlButtons` API is unavailable. [module.js:86-96, roster-strip.hbs, ScryingPoolStrip.js]
+- [x] [Review][Patch] Avatar Image Missing Alt Text — Changed `alt="" aria-hidden="true"` to `alt="Avatar of {{name}}"` in participant-card.hbs. Screen readers now announce avatar identity. [participant-card.hbs:6]
+- [x] [Review][Patch] No Error Handling in buildBoardContext — Wrapped in try/catch returning `{ participants: [], isEmpty: true }` on error. Graceful degradation prevents board render crash. [ParticipantCard.js:52-60]
+- [x] [Review][Patch] Redundant aria-disabled on Native Buttons — Removed `aria-disabled="true"` from disabled buttons in directors-board.hbs. Native `disabled` attribute is sufficient for AT. [directors-board.hbs:19-22]
+
+#### Deferred
+- [x] [Review][Defer] No Error Handling in _savePosition [DirectorsBoard.js:160-167] — `game.user?.setFlag(...)` called without try/catch. Pre-existing pattern in codebase (same as ScryingPoolStrip). Not introduced by Story 2.2.
+- [x] [Review][Defer] CSS Includes sp-state-pending Class [_participant-card.less:18] — Defines `sp-state-pending` class but Story 2.2 only specifies 8 states. Relates to StateStore/VisibilityManager from Epic 1, not introduced by this story.

+# Story 2.3: Director's Board — Bulk Actions, Spotlight & Keyboard Shortcuts
+
+Status: done
+
+## Story
+
+As a **GM**,
+I want to show or hide all participants at once, spotlight a single feed, and undo these bulk actions instantly,
+so that I can execute camera arrangements in a single action without toggling participants one by one.
+
+## Acceptance Criteria
+
+1. **Given** the Director's Board is open
+   **When** the GM clicks "Show All"
+   **Then** all participants' states are set to `active` (excluding `ghost`-state participants)
+   **And** the action is broadcast to all clients
+
+2. **Given** the Director's Board is open
+   **When** the GM clicks "Hide All"
+   **Then** all participants' states are set to `hidden` (excluding `ghost`-state participants)
+   **And** the action is broadcast to all clients
+
+3. **Given** the GM has just executed "Show All" or "Hide All"
+   **When** the GM clicks "Undo"
+   **Then** the Visibility Matrix is immediately restored to the state before the bulk action
+   **And** no second undo is available (single-step undo only)
+
+4. **Given** a participant card is focused
+   **When** the GM presses `Ctrl+Shift+P`
+   **Then** that participant's feed is shown and all others are hidden in a single action
+   **And** the pre-spotlight Visibility Matrix is stored as a snapshot
+
+5. **Given** Spotlight is active
+   **When** the GM clicks "Restore"
+   **Then** the Visibility Matrix reverts to the pre-spotlight snapshot
+   **And** "Restore" is distinct from the bulk action Undo affordance
+
+6. **Given** `Ctrl+Shift+S` or `Ctrl+Shift+H` is pressed
+   **When** the event fires
+   **Then** "Show All" or "Hide All" executes as if the button were clicked
+
+7. **Given** the GM presses `?` in the Director's Board
+   **When** the event fires
+   **Then** a shortcut reference panel opens listing all keyboard shortcuts with their current bindings
+
+8. **Given** the GM navigates to keyboard shortcut settings
+   **When** they open module settings
+   **Then** `Ctrl+Shift+V`, `Ctrl+Shift+S`, `Ctrl+Shift+H`, `Ctrl+Shift+P` are all configurable
+   **And** the `?` panel reflects the currently configured bindings
+
+## Tasks / Subtasks
+
+- [x] Task 1: Fix `_dispatchToggle` calling convention in `DirectorsBoard.js` (AC: foundational bug fix from Story 2.2)
+  - [x] 1.1: Add `import { generateOpId } from '../../utils/uuid.js';` at top of `DirectorsBoard.js`
+  - [x] 1.2: Rewrite `_dispatchToggle(userId)` to use positional args: `controller.action('board', userId, targetState, opId, baseRevision)` — matching ScryingPoolStrip's `_dispatchAction` pattern
+  - [x] 1.3: Update existing `_dispatchToggle` tests in `tests/unit/ui/gm/DirectorsBoard.test.js` — replace `expect(controller.action).toHaveBeenCalledWith({ userId, targetState })` with `expect(controller.action).toHaveBeenCalledWith('board', userId, targetState, expect.any(String), expect.any(Number))`; add `getRevision: vi.fn(() => 0)` to the controller mock
+
+- [x] Task 2: Implement `showAll()` and `hideAll()` methods on `DirectorsBoard` (AC: 1, 2, 3)
+  - [x] 2.1: Write TDD red tests in `DirectorsBoard.test.js` — new `describe('showAll()')` and `describe('hideAll()')` blocks
+  - [x] 2.2: Implement `showAll()`: capture pre-action snapshot → `this._undoSnapshot = new Map(nonGhostUsers.map(u => [u.id, this._stateStore.getState(u.id)]))` → call `controller.action('board', userId, 'active', opId, baseRevision)` for each non-ghost participant → clear `this._spotlightSnapshot` (spotlight superseded)
+  - [x] 2.3: Implement `hideAll()`: same pattern but target state `'hidden'` → similarly clears `_spotlightSnapshot`
+  - [x] 2.4: `ghost` exclusion rule: check `this._stateStore.getState(userId) === 'ghost'` before acting; skip those users
+  - [x] 2.5: Skip participants that already have a pending op: check `this._controller.hasPendingOp?.(userId)`
+  - [x] 2.6: After showAll/hideAll, trigger re-render to reflect Undo button visibility: `if (this.rendered) this.render({ force: true })`
+  - [x] 2.7: Green all showAll/hideAll tests
+
+- [x] Task 3: Implement `undo()` method and single-step undo state (AC: 3)
+  - [x] 3.1: Add `this._undoSnapshot = null;` and `this._spotlightSnapshot = null;` to constructor
+  - [x] 3.2: Write TDD red tests: undo restores all non-ghost participants to snapshot values; undo clears `_undoSnapshot`; undo is no-op when `_undoSnapshot` is null; second undo unavailable after first
+  - [x] 3.3: Implement `undo()`: guard `if (!this._undoSnapshot) return`; for each `[userId, targetState]` entry in `_undoSnapshot`: skip ghost-state users and pending-op users; call `controller.action('board', userId, targetState, opId, baseRevision)`; then `this._undoSnapshot = null`; trigger re-render
+  - [x] 3.4: Green all undo tests
+
+- [x] Task 4: Implement `spotlight(userId)` and `restoreSpotlight()` methods (AC: 4, 5)
+  - [x] 4.1: Write TDD red tests: spotlight captures pre-spotlight snapshot; spotlight sets focused user active + all others hidden (excluding ghost); restore reverts all participants; restore clears `_spotlightSnapshot`; calling spotlight clears `_undoSnapshot`
+  - [x] 4.2: Implement `spotlight(userId)`: guard if `!userId`; capture `this._spotlightSnapshot = new Map(nonGhostUsers.map(u => [u.id, this._stateStore.getState(u.id)]))` → clear `this._undoSnapshot` (spotlight supersedes bulk undo); iterate non-ghost users: `active` for the spotlighted user, `hidden` for all others; trigger re-render
+  - [x] 4.3: Implement `restoreSpotlight()`: guard `if (!this._spotlightSnapshot) return`; for each `[userId, targetState]` in snapshot: skip ghost + pending-op; call `controller.action('board', userId, targetState, opId, baseRevision)`; `this._spotlightSnapshot = null`; trigger re-render
+  - [x] 4.4: Add `spotlightFocused()` public method: reads `document.activeElement?.dataset?.userId` from within the board's element; calls `spotlight(userId)` if valid — used by keyboard shortcut callback
+  - [x] 4.5: Green all spotlight tests
+
+- [x] Task 5: Update `_prepareContext()` to expose bulk-action state flags (AC: 3, 5)
+  - [x] 5.1: Extend `_prepareContext()` return value with: `{ ..., hasUndo: this._undoSnapshot !== null, hasRestore: this._spotlightSnapshot !== null }`
+  - [x] 5.2: Update `_prepareContext` tests to verify the two new fields
+
+- [x] Task 6: Update `templates/directors-board.hbs` (AC: 1, 2, 3, 5, 7)
+  - [x] 6.1: Add a `<div class="directors-board__bulk-bar">` section between the grid and footer with:
+    - "Show All" button: `<button type="button" data-action="show-all" ...>`
+    - "Hide All" button: `<button type="button" data-action="hide-all" ...>`
+    - Conditional Undo: `{{#if hasUndo}}<button type="button" data-action="undo" ...>{{/if}}`
+    - Conditional Restore: `{{#if hasRestore}}<button type="button" data-action="restore-spotlight" ...>{{/if}}`
+  - [x] 6.2: All button labels via `{{localize "video-view-manager.directorsBoard.bulk.*"}}` keys (never inline English)
+  - [x] 6.3: Undo and Restore buttons use distinct styling (Undo = secondary; Restore = spotlight-accent)
+  - [x] 6.4: Add `<button type="button" class="directors-board__help-btn" data-action="open-shortcut-panel" aria-label="...">?</button>` to the title bar area or bulk-bar
+
+- [x] Task 7: Wire bulk-action event delegation in `_onRender()` (AC: 1, 2, 3, 5, 7)
+  - [x] 7.1: Extend the existing delegated `click` listener in `_onRender()` to handle new `data-action` values:
+    - `show-all` → `this.showAll()`
+    - `hide-all` → `this.hideAll()`
+    - `undo` → `this.undo()`
+    - `restore-spotlight` → `this.restoreSpotlight()`
+    - `open-shortcut-panel` → `this._openShortcutPanel()`
+  - [x] 7.2: Add `?` keydown handler in `_onKeydown()`: `if (e.key === '?') { e.preventDefault(); this._openShortcutPanel(); }`
+  - [x] 7.3: Extend `Ctrl+Shift+P` keyboard shortcut handler in `_onKeydown()`: `if (e.ctrlKey && e.shiftKey && e.code === 'KeyP') { e.preventDefault(); this.spotlightFocused(); }`
+
+- [x] Task 8: Implement `_openShortcutPanel()` (AC: 7, 8)
+  - [x] 8.1: Implement `_openShortcutPanel()` method: reads current bindings from `game.keybindings.bindings` for each registered action key (`openDirectorsBoard`, `showAll`, `hideAll`, `spotlightParticipant`); builds an HTML string listing each shortcut name + current binding; opens as a native Foundry `Dialog.prompt()` or `new Dialog({ ... }).render(true)` — no custom template needed
+  - [x] 8.2: i18n all shortcut names — use `adapter.i18n.localize()` for label strings (or fallback to display name string if localize not available)
+  - [x] 8.3: Panel shows: "Open/Close Board: Ctrl+Shift+V", "Show All: Ctrl+Shift+S", "Hide All: Ctrl+Shift+H", "Spotlight: Ctrl+Shift+P" (reflecting current configured bindings)
+
+- [x] Task 9: Register new keybindings in `module.js` (AC: 6, 8)
+  - [x] 9.1: Register `scrying-pool.showAll` keybinding in `Hooks.once('init')`: `key: 'KeyS', modifiers: ['Control', 'Shift']`, `restricted: true`, `onDown: () => directorsBoard?.showAll()`
+  - [x] 9.2: Register `scrying-pool.hideAll` keybinding: `key: 'KeyH', modifiers: ['Control', 'Shift']`, `restricted: true`, `onDown: () => directorsBoard?.hideAll()`
+  - [x] 9.3: Register `scrying-pool.spotlightParticipant` keybinding: `key: 'KeyP', modifiers: ['Control', 'Shift']`, `restricted: true`, `onDown: () => directorsBoard?.spotlightFocused()`
+  - [x] 9.4: Update the module.js header comment to include Story 2.3 keybinding wiring
+
+- [x] Task 10: Add i18n keys in `lang/en.json` (AC: 1, 2, 3, 5, 7)
+  - [x] 10.1: Add `video-view-manager.directorsBoard.bulk.showAll` = `"Show All"`
+  - [x] 10.2: Add `video-view-manager.directorsBoard.bulk.hideAll` = `"Hide All"`
+  - [x] 10.3: Add `video-view-manager.directorsBoard.bulk.undo` = `"Undo"`
+  - [x] 10.4: Add `video-view-manager.directorsBoard.bulk.restore` = `"Restore"`
+  - [x] 10.5: Add `video-view-manager.directorsBoard.bulk.spotlight` = `"Spotlight"`
+  - [x] 10.6: Add `video-view-manager.directorsBoard.shortcuts.title` = `"Keyboard Shortcuts"`
+  - [x] 10.7: Add `video-view-manager.directorsBoard.shortcuts.openBoard` = `"Open/Close Board"`
+  - [x] 10.8: Add `video-view-manager.directorsBoard.shortcuts.showAll` = `"Show All Participants"`
+  - [x] 10.9: Add `video-view-manager.directorsBoard.shortcuts.hideAll` = `"Hide All Participants"`
+  - [x] 10.10: Add `video-view-manager.directorsBoard.shortcuts.spotlight` = `"Spotlight Focused Participant"`
+  - [x] 10.11: Add `video-view-manager.directorsBoard.shortcuts.openPanel` = `"Open Shortcut Reference"`
+  - [x] 10.12: Add keybinding label and hint strings under `video-view-manager.keybindings.showAll` / `hideAll` / `spotlightParticipant`
+
+- [x] Task 11: Add bulk-action bar CSS in `styles/components/_directors-board.less` (AC: 1, 2, 3, 5)
+  - [x] 11.1: Add `.directors-board__bulk-bar` styles: `display: flex; gap: 8px; padding: 8px; border-top: 1px solid var(--sp-border);`
+  - [x] 11.2: Style "Show All" / "Hide All" as primary action buttons using existing `--sp-*` tokens
+  - [x] 11.3: Style "Undo" as secondary; "Restore" with a spotlight-accent color (distinct from Undo — per AC 5)
+  - [x] 11.4: Add `.directors-board__help-btn` styles: small circular button, top-right positioning within title/header area
+
+- [x] Task 12: Pipeline verification
+  - [x] 12.1: `npm run lint` exits 0 for all modified files
+  - [x] 12.2: `npm run test` exits 0 — expected: 383 baseline + new bulk/spotlight/undo/shortcut tests (~25–35 new tests)
+
+## Dev Notes
+
+### Critical Bug Fix from Story 2.2 (MUST address in this story)
+
+`DirectorsBoard._dispatchToggle()` currently calls:
+```js
+this._controller.action({ userId, targetState }); // ← WRONG: passing object
+```
+
+But `ScryingPoolController.action()` signature is **positional**:
+```js
+action(source, participantId, targetState, opId, baseRevision)
+```
+
+**Fix** — match `ScryingPoolStrip._dispatchAction()` pattern exactly:
+```js
+import { generateOpId } from '../../utils/uuid.js'; // add at top
+
+_dispatchToggle(userId) {
+  if (!userId) return;
+  if (this._controller.hasPendingOp?.(userId)) return;
+  const currentState = this._stateStore.getState(userId) ?? 'active';
+  const targetState = resolveToggleTarget(currentState);
+  const opId = generateOpId();
+  const baseRevision = this._controller.getRevision?.(userId) ?? 0;
+  this._controller.action('board', userId, targetState, opId, baseRevision);
+}
+```
+
+**Update existing `_dispatchToggle` tests** to expect positional args:
+```js
+// Before (Story 2.2):
+expect(controller.action).toHaveBeenCalledWith({ userId: 'u1', targetState: 'hidden' });
+
+// After (Story 2.3 fix):
+expect(controller.action).toHaveBeenCalledWith('board', 'u1', 'hidden', expect.any(String), expect.any(Number));
+```
+
+Also add `getRevision: vi.fn(() => 0)` to the `controller` mock in `beforeEach`.
+
+### Bulk Action Implementation Pattern
+
+All bulk methods follow the same structure. Reference `ScryingPoolStrip._dispatchAction()` for single-op pattern. Bulk ops fire the same call per-participant:
+
+```js
+showAll() {
+  const users = this._adapter.users.all();
+  // Capture pre-action snapshot (non-ghost only)
+  this._undoSnapshot = new Map(
+    users
+      .filter(u => this._stateStore.getState(u.id) !== 'ghost')
+      .map(u => [u.id, this._stateStore.getState(u.id)])
+  );
+  this._spotlightSnapshot = null; // bulk supersedes spotlight restore
+
+  for (const u of users) {
+    const currentState = this._stateStore.getState(u.id);
+    if (currentState === 'ghost') continue;                  // FR-12: exclude ghost
+    if (this._controller.hasPendingOp?.(u.id)) continue;    // skip in-flight

+```
+
+- `showAll()` / `hideAll()` → set `_undoSnapshot`, clear `_spotlightSnapshot`
+- `spotlight()` → set `_spotlightSnapshot`, clear `_undoSnapshot`
+- `undo()` → read `_undoSnapshot`, set to null (single-step — second undo unavailable)
+- `restoreSpotlight()` → read `_spotlightSnapshot`, set to null
+
+### Ghost Exclusion Rule (FR-12)
+
+```js
+// ALWAYS exclude ghost state from bulk ops — spec is explicit (FR-12, FR-13)
+if (this._stateStore.getState(userId) === 'ghost') continue;
+```
+
+Ghost participants are leaving the session; mutating their state causes visual glitches. Check the **current live state** from `stateStore`, NOT the snapshot state.
+
+### Spotlight Method
+
+```js
+spotlight(userId) {
+  if (!userId) return;
+  const users = this._adapter.users.all();
+  const nonGhost = users.filter(u => this._stateStore.getState(u.id) !== 'ghost');
+
+  // Capture pre-spotlight snapshot
+  this._spotlightSnapshot = new Map(nonGhost.map(u => [u.id, this._stateStore.getState(u.id)]));
+  this._undoSnapshot = null; // spotlight supersedes bulk undo
+
+  for (const u of nonGhost) {
+    if (this._controller.hasPendingOp?.(u.id)) continue;
+    const targetState = u.id === userId ? 'active' : 'hidden';
+    const opId = generateOpId();
+    const baseRevision = this._controller.getRevision?.(u.id) ?? 0;
+    this._controller.action('board', u.id, targetState, opId, baseRevision);
+  }
+  if (this.rendered) this.render({ force: true });
+}
+
+spotlightFocused() {
+  // Reads currently focused card's userId — only valid when board DOM exists
+  const focusedUserId = this.element?.querySelector('[data-user-id]:focus')?.dataset?.userId;
+  if (!focusedUserId) return;
+  this.spotlight(focusedUserId);
+}
+```
+
+### Keyboard Shortcut Delegation in `_onKeydown()`
+
+Extend existing `_onKeydown(e)` method to handle Story 2.3 shortcuts:
+
+```js
+_onKeydown(e) {
+  // ... existing ArrowKey / Space / Enter navigation (unchanged) ...
+
+  // Story 2.3: Spotlight focused participant
+  if (e.ctrlKey && e.shiftKey && e.code === 'KeyP') {
+    e.preventDefault();
+    this.spotlightFocused();
+    return;
+  }
+
+  // Story 2.3: Shortcut reference panel
+  if (e.key === '?') {
+    e.preventDefault();
+    this._openShortcutPanel();
+    return;
+  }
+}
+```
+
+**Note:** `Ctrl+Shift+S` and `Ctrl+Shift+H` are registered as global Foundry keybindings in `module.js`, NOT as keydown handlers inside the board. This matches the spec ("executes as if the button were clicked" — globally, not just when board is focused).
+
+### `_prepareContext()` Extension
+
+```js
+async _prepareContext() {
+  const base = buildBoardContext(this._stateStore, this._controller, this._adapter);
+  return {
+    ...base,
+    hasUndo: this._undoSnapshot !== null,
+    hasRestore: this._spotlightSnapshot !== null,
+  };
+}
+```
+
+### Shortcut Reference Panel (`_openShortcutPanel()`)
+
+Reads live bindings from Foundry's keybindings registry, builds a simple HTML panel. Reference pattern:
+
+```js
+_openShortcutPanel() {
+  const getBinding = (action) => {
+    const binding = game.keybindings?.bindings?.get(`scrying-pool.${action}`)?.[0];
+    if (!binding) return '—';
+    const mods = (binding.modifiers ?? []).join('+');
+    return mods ? `${mods}+${binding.key}` : binding.key;
+  };
+
+  const rows = [
+    ['openDirectorsBoard', 'directorsBoard.shortcuts.openBoard'],
+    ['showAll',            'directorsBoard.shortcuts.showAll'],
+    ['hideAll',            'directorsBoard.shortcuts.hideAll'],
+    ['spotlightParticipant', 'directorsBoard.shortcuts.spotlight'],
+  ].map(([action, labelKey]) =>
+    `<tr><td>${adapter.i18n.localize(`video-view-manager.${labelKey}`)}</td>
+         <td><kbd>${getBinding(action)}</kbd></td></tr>`
+  ).join('');
+
+  new Dialog({
+    title: adapter.i18n.localize('video-view-manager.directorsBoard.shortcuts.title'),
+    content: `<table class="sp-shortcut-table"><tbody>${rows}</tbody></table>`,
+    buttons: { close: { label: 'Close', callback: () => {} } },
+    default: 'close',
+  }).render(true);
+}
+```
+
+Use `typeof Dialog !== 'undefined'` guard (or `game?.ui`) for test compatibility — `_openShortcutPanel` does NOT need unit tests (it's a passthrough to Foundry Dialog API).
+
+### Module.js Keybinding Registration (Story 2.3 additions)
+
+Add in `Hooks.once('init')`, after the existing `openDirectorsBoard` registration:
+
+```js
+// Story 2.3: Show All / Hide All / Spotlight keybindings (GM only, configurable)
+game.keybindings.register('scrying-pool', 'showAll', {
+  name: game.i18n?.localize('video-view-manager.keybindings.showAll.name') ?? 'Show All Participants',
+  hint: game.i18n?.localize('video-view-manager.keybindings.showAll.hint') ?? 'Sets all participants visible',
+  editable: [{ key: 'KeyS', modifiers: ['Control', 'Shift'] }],
+  restricted: true,
+  onDown: () => directorsBoard?.showAll(),
+});
+game.keybindings.register('scrying-pool', 'hideAll', {
+  name: game.i18n?.localize('video-view-manager.keybindings.hideAll.name') ?? 'Hide All Participants',
+  hint: game.i18n?.localize('video-view-manager.keybindings.hideAll.hint') ?? 'Hides all participants',
+  editable: [{ key: 'KeyH', modifiers: ['Control', 'Shift'] }],
+  restricted: true,
+  onDown: () => directorsBoard?.hideAll(),
+});
+game.keybindings.register('scrying-pool', 'spotlightParticipant', {
+  name: game.i18n?.localize('video-view-manager.keybindings.spotlightParticipant.name') ?? 'Spotlight Focused Participant',
+  hint: game.i18n?.localize('video-view-manager.keybindings.spotlightParticipant.hint') ?? 'Shows focused participant and hides all others',
+  editable: [{ key: 'KeyP', modifiers: ['Control', 'Shift'] }],
+  restricted: true,
+  onDown: () => directorsBoard?.spotlightFocused(),
+});
+```
+
+**Note:** `game.i18n?.localize()` with fallback is used here because keybindings register in `Hooks.once('init')` which fires before `ready`; i18n may not be fully loaded. The fallback English string is safe.
+
+### Test Patterns for Bulk Actions

+```js
+// In DirectorsBoard.test.js — add to controller mock:

+### File Structure for This Story
+
+**Modified files:**
+```
+src/ui/gm/DirectorsBoard.js              ← MODIFIED (bulk/spotlight/undo/shortcuts)
+templates/directors-board.hbs           ← MODIFIED (bulk action bar, undo/restore buttons)
+styles/components/_directors-board.less ← MODIFIED (bulk bar styles)
+module.js                                ← MODIFIED (3 new keybinding registrations)
+lang/en.json                             ← MODIFIED (bulk + shortcuts i18n keys)
+tests/unit/ui/gm/DirectorsBoard.test.js ← MODIFIED (fix existing tests + add bulk/spotlight tests)
+```
+
+**No new files required** — all changes are additions/modifications to existing files.
+
+### Import Boundary Reminder (Hard Rule — ESLint-enforced)
+
+```
+src/ui/ → may import: src/core/, src/contracts/, src/utils/ ONLY
+```
+
+`generateOpId` is in `src/utils/uuid.js` — this import is allowed. Do NOT import from `src/foundry/` inside `src/ui/`.
+
+### ApplicationV2 Re-render Pattern
+
+After any state-mutating method (showAll, hideAll, undo, spotlight, restoreSpotlight), always trigger re-render to update the hasUndo/hasRestore flags in the template:
+
+```js
+if (this.rendered) this.render({ force: true });
+```
+
+This is the existing pattern from `_onStateChanged()` — no change needed to the re-render mechanism.
+
+### Undo does NOT use `stateStore.setMatrix()`
+
+Individual `controller.action()` calls per participant ensure socket broadcast. `setMatrix()` is reserved for Scene Preset apply (Story 3.1) and DOES NOT emit per-participant socket messages (per architecture deferred item: "No handling of setMatrix hook events in NotificationBus").
+
+Using `controller.action()` per participant for undo/restore guarantees:
+- Socket broadcast to all clients ✅
+- Optimistic state update ✅
+- Pending-op tracking (revert on timeout) ✅
+- `NotificationBus` triggers per-participant notifications ✅
+
+### Story 2.2 Completion State (Baseline)
+
+All 383 tests passing. Files created in Story 2.2:
+- `src/ui/shared/ParticipantCard.js` — `buildCardContext()`, `buildBoardContext()`, `resolveToggleTarget()`
+- `src/ui/gm/DirectorsBoard.js` — ApplicationV2 window with toggle, keyboard nav, position persistence
+- `templates/directors-board.hbs` — grid layout, participant cards, disabled footer preset buttons
+- `templates/participant-card.hbs` — `role="listitem"`, `data-user-id`, toggle overlay
+- `styles/components/_directors-board.less` — CSS grid, empty state, footer
+- `styles/components/_participant-card.less` — 80×100px card, sp-state-* variants
+- `module.js` — import, `let directorsBoard`, `Ctrl+Shift+V` keybinding, sidebar hook, ready wiring
+
+### Project Structure Notes
+
+- `src/ui/gm/DirectorsBoard.js` — already exists, extend in place
+- All new methods (`showAll`, `hideAll`, `undo`, `spotlight`, `restoreSpotlight`, `spotlightFocused`, `_openShortcutPanel`) are additions to the `DirectorsBoard` class
+- CSS classes follow BEM with `directors-board__*` namespace already established in `_directors-board.less`
+- i18n keys follow the established `video-view-manager.directorsBoard.*` namespace

+## Dev Agent Record
+
+### Agent Model Used
+
+Claude Sonnet 4.6
+
+### Debug Log References
+
+- Bug discovered in Task 1: `_dispatchToggle()` was calling `controller.action({ userId, targetState })` (object) instead of positional args. Fixed to match `ScryingPoolStrip._dispatchAction()` pattern.
+- `spotlight()` captures snapshot from ALL users (including ghost) so restoreSpotlight has complete state picture, but only dispatches to non-ghost users.
+
+### Completion Notes List
+
+- ✅ Task 1: Fixed `_dispatchToggle` positional args bug; updated all related tests
+- ✅ Task 2: Implemented `showAll()`/`hideAll()` via shared `_executeBulk()` helper with ghost exclusion and pending-op skip
+- ✅ Task 3: Implemented `undo()` with single-step semantics; `_undoSnapshot` nulled immediately on use
+- ✅ Task 4: Implemented `spotlight()`, `restoreSpotlight()`, `spotlightFocused()`; mutual exclusion of snapshots enforced
+- ✅ Task 5: Extended `_prepareContext()` with `hasUndo`/`hasRestore` flags; 4 new tests
+- ✅ Task 6: Updated `directors-board.hbs` with bulk-bar; all labels via i18n keys; conditional Undo/Restore
+- ✅ Task 7: Rewrote `_onRender()` click handler to switch on `data-action`; added focusin listener for `_focusedUserId`; extended `_onKeydown()` with `?` and `Ctrl+Shift+P`
+- ✅ Task 8: `_openShortcutPanel()` reads live keybinding bindings with defaults fallback; renders via `new Dialog()`
+- ✅ Task 9: Registered `showAll`, `hideAll`, `spotlightParticipant` keybindings in `module.js`
+- ✅ Task 10: Added all i18n keys under `directorsBoard.bulk.*`, `directorsBoard.shortcuts.*`, `keybindings.*`
+- ✅ Task 11: Added `.directors-board__bulk-bar`, `.directors-board__bulk-btn` (with `--undo`/`--restore` modifiers), `.directors-board__help-btn` CSS
+- ✅ Task 12: lint (no new errors introduced); 412 tests pass (+29 from 383 baseline)
+
+### File List
+
+- `src/ui/gm/DirectorsBoard.js` — major extension: `showAll`, `hideAll`, `_executeBulk`, `undo`, `spotlight`, `restoreSpotlight`, `spotlightFocused`, `_openShortcutPanel`; extended `_onRender`, `_onKeydown`, `_prepareContext`; constructor fields; `/* global Dialog */`
+- `tests/unit/ui/gm/DirectorsBoard.test.js` — +29 tests: showAll/hideAll (9), undo (6), spotlight/restore/spotlightFocused (10), _prepareContext hasUndo/hasRestore (4)
+- `templates/directors-board.hbs` — added bulk-bar with Show All, Hide All, conditional Undo/Restore, help button
+- `module.js` — registered 3 new keybindings: showAll, hideAll, spotlightParticipant
+- `lang/en.json` — added bulk.*, shortcuts.*, keybindings.* i18n keys
+- `styles/components/_directors-board.less` — added bulk-bar, bulk-btn (undo/restore variants), help-btn styles
+
+### Review Findings
+
+#### Decision-Needed (Resolved)
+- [x] [Review][Decision] Keybinding namespace inconsistency — Migrated all keybindings to `scrying-pool` namespace to align with existing module patterns
+- [x] [Review][Decision] Keybindings reference undefined directorsBoard — Implemented lazy initialization pattern: callbacks check directorsBoard existence before calling
+- [x] [Review][Decision] Import boundary violation — Moved `buildBoardContext` and `resolveToggleTarget` from `ParticipantCard.js` to new `src/utils/boardUtils.js`
+
+#### Patch
+- [x] [Review][Patch] Event listeners broken after close/reopen [DirectorsBoard.js] — Removed isFirstRender guard; added listener cleanup and re-registration on every render
+- [x] [Review][Patch] No position loading from saved state [DirectorsBoard.js] — Added _loadPosition() in constructor to read saved position from user flags
+- [x] [Review][Patch] spotlight() lacks userId validation [DirectorsBoard.js] — Added null/undefined guard and validation of userId against non-ghost users
+- [x] [Review][Patch] DOM listener memory leak [DirectorsBoard.js] — Added listener cleanup in _onClose and proper cleanup on re-render
+- [x] [Review][Patch] No scene control button cleanup [module.js] — Added directorsBoardButtonAdded flag and duplicate check in getSceneControlButtons hook
+- [x] [Review][Patch] Race condition in _executeBulk [DirectorsBoard.js] — Capture all user states in single pass before filtering and snapshot
+- [x] [Review][Patch] Race condition in spotlight [DirectorsBoard.js] — Get all user states atomically before filtering and snapshot
+- [x] [Review][Patch] Ghost state transition in restoreSpotlight not handled [DirectorsBoard.js] — Check current state (not just snapshot) when restoring to avoid ghost transitions
+- [x] [Review][Patch] _openShortcutPanel swallows Dialog.render errors [DirectorsBoard.js] — Added try/catch with error logging; checks both namespaces for keybindings
+- [x] [Review][Patch] _savePosition swallows setFlag errors [DirectorsBoard.js] — Added try/catch with error logging
+- [x] [Review][Patch] _onKeydown wraps focus incorrectly when idx=-1 [DirectorsBoard.js] — Added guard to return early if idx < 0
+- [x] [Review][Patch] buildCardContext defaults null state to active [ParticipantCard.js:48] — Kept existing behavior; documented as pre-existing
+- [x] [Review][Patch] Migrate all keybindings to scrying-pool namespace [module.js] — Updated namespace from video-view-manager to scrying-pool for showAll, hideAll, spotlightParticipant
+- [x] [Review][Patch] Move buildBoardContext/resolveToggleTarget to src/utils/ [DirectorsBoard.js, ParticipantCard.js] — Created boardUtils.js with shared utilities; updated imports
+
+#### Defer
+- [x] [Review][Defer] buildCardContext null state defaults to active [ParticipantCard.js:48] — deferred, pre-existing issue in ParticipantCard.js
+
+#### Dismiss
+- [x] [Review][Dismiss] Unusual void parameter suppression [DirectorsBoard.js:272] — dismissed as stylistic
+- [x] [Review][Dismiss] Outdated module comment [module.js:14-18] — dismissed as documentation
+- [x] [Review][Dismiss] Inconsistent module identifiers — dismissed as cosmetic

+
+### Code Review Fixes Applied
+
+**Fix 1: module.js wiring (HIGH)**
+- Added imports for ConfirmationBar and StripOverlayLayer
+- Constructed ScenePresetManager with visibilityManager in ready hook
+- Created StripOverlayLayer and ConfirmationBar instances
+- Registered updateScene hook to trigger scenePresetManager.onSceneActivate()
+- Registered autoApplyEnabled world setting
+
+**Fix 2: Settings key namespace (HIGH)**
+- Changed `scrying-pool.autoApplyEnabled` to `video-view-manager.autoApplyEnabled` in ScenePresetManager.onSceneActivate()
+- Settings are now properly namespaced under the module's registered namespace
+
+**Fix 3: Socket loop prevention (HIGH)**
+- Added `emitSocket` option parameter to load() method (default: true)
+- load() now only emits PRESET_APPLIED when emitSocket is true
+- module.js socket handler passes `{ emitSocket: false }` to prevent loop
+- PresetLoadDialog continues to emit (manual GM action)
+
+**Fix 4: Auto-apply config preservation (MEDIUM)**
+- Modified _saveScenePresets() to read existing autoApply config from scene flag
+- Preserves autoApply setting when saving presets
+- Prevents loss of per-scene auto-apply configuration
+
+**Fix 5: Scene timer cleanup (MEDIUM)**
+- Added _clearAllTimers() method to clear ALL pending timers
+- onSceneActivate() now calls _clearAllTimers() before applying new preset
+- Prevents old scene's timer from firing after switching scenes
+
+**Task 1 Implementation Notes:**
+- Extended ScenePresetManager constructor to accept optional `visibilityManager` parameter
+- Added constants: MAX_PREDELAY_MS (5000), MIN_PREDELAY_MS (0)
+- Implemented `onSceneActivate(scene)` with full auto-apply logic chain
+- Implemented `applyPreset(presetName, options)` supporting autoApplied flag
+- Implemented `configureAutoApply(scene, config)` with validation
+- Implemented `_getAutoApplyConfig(flagData)` with default fallback
+- Implemented `_applyWithDelay(scene, presetName, delayMs)` with timer storage
+- Implemented `_clearSceneTimer(scene)` for cleanup
+- Implemented `_getSceneFlagData(scene)` for safe flag access
+- All 61 tests passing including 15 new Story 3.2 tests

-# Acceptance Auditor Review Layer
-
-## ROLE
-You are **Acceptance Auditor** — a compliance checker. You review code changes against the specification and acceptance criteria. You must verify that the implementation matches the spec intent.
-
-## INPUTS
-1. **Diff** (below)
-2. **Spec file**: `_bmad-output/implementation-artifacts/1-1-module-scaffold-cicd-pipeline-and-design-token-system.md`
-3. **Context docs**: Any documents referenced in the spec's frontmatter `context` field (none in this case)
-
-## MISSION
-Check for:
-- **Violations of acceptance criteria** (AC #1, #2, #3... from the spec)
-- **Deviations from spec intent** (implementation does something different than described)
-- **Missing implementation** (spec says X should exist/behave a certain way, but it's not in the diff)
-- **Contradictions** (code violates constraints stated in the spec)
-
-For each finding, identify:
-- Which AC or spec section it violates
-- Exact evidence from the diff
-- The expected vs actual behavior
-
-## OUTPUT FORMAT
-Output ONLY a Markdown list of findings. No preamble, no summary. Each finding:
-```markdown
-- **[AC#X / SPEC]** Short title — file:line — what violates which AC + evidence
-```
-
-## SPEC CONTENT
-# Story 1.1: Module Scaffold, CI/CD Pipeline & Design Token System
-
-Status: review
-
-## Story
-
-As a **developer**,
-I want a fully configured module scaffold with the complete `--sp-*` design token system, contract files, tooling, and CI,
-so that every subsequent story builds on enforced boundaries, verified tooling, and a stable design language.
-
-## Acceptance Criteria
-
-1. **Given** the repository is checked out fresh **When** `npm install && npm run lint && npm run typecheck && npm run test` are executed **Then** all commands exit 0 **And** `npm run build` produces `module.zip` containing `module.json`, `scripts/`, `styles/`, `templates/`, `lang/`
-
-2. **Given** the module is installed in FoundryVTT v14 **When** FoundryVTT loads **Then** the module activates with no console errors and `game.modules.get('video-view-manager').active === true`
-
-3. **Given** a developer writes an exported function without a JSDoc comment **When** `npm run lint` runs **Then** `eslint` reports a `jsdoc/require-jsdoc` violation
-
-4. **Given** a source file imports from a restricted layer **When** `npm run lint` runs **Then** `import/no-restricted-paths` reports a boundary violation
-
-5. **Given** a Gitea push is made **When** the CI workflow runs **Then** lint, typecheck, and test all run; a failing test fails the workflow
-
-6. **Given** a developer writes module CSS using a Foundry `--color-*`/`--font-*`/`--border-*` token directly inside `.scrying-pool` CSS **When** the linting convention is enforced **Then** a violation is reported — all Foundry tokens must be aliased through `--sp-*`
-
-7. **Given** a developer renders any participant state **When** they look up the token system in `styles/scrying-pool.less` **Then** all token layers are defined:
-   - Layer 1: SP semantic aliases (`--sp-surface`, `--sp-border`, `--sp-text-primary`, `--sp-text-secondary`, `--sp-accent`, `--sp-focus`) mapping to Foundry tokens with hardcoded fallbacks
-   - Layer 2: SP Participant State tokens for all 8 states (`active`, `hidden`, `self-muted`, `offline`, `cam-lost`, `reconnecting`, `never-connected`, `ghost`)
-   - Layer 3: SP Urgency + Motion tokens (`--sp-urgency-director`, `--sp-urgency-awareness`, `--sp-fade-hide`, `--sp-pulse-reconnecting`, `--sp-shimmer-degraded`, `--sp-toast-delay`)
-   - **And** the `VisibilityBadge` `:root` exception is documented: badge tokens declared on `:root` because badge mounts outside `.scrying-pool` root
-   - **And** all animated token usages gated under `@media (prefers-reduced-motion: no-preference)`
-
-8. **Given** the 4 contract files exist **When** a story imports `src/contracts/visibility-matrix.js` **Then** it exports a canonical shape constant, a factory function (`createVisibilityMatrix()`), and a guard/validator function (`isValidVisibilityMatrix(data)`) **And** the same factory + validator pattern applies to `socket-message.js`, `pending-op.js`, `scene-preset.js`

-
-❌ `src/core/` importing `src/foundry/`, `src/ui/`, `src/notifications/`, or `src/presets/` is a hard violation.
-❌ `src/foundry/` importing `src/core/` or `src/ui/` is a hard violation.
-
-These must be configured as `import/no-restricted-paths` zones — not aspirational documentation.
-
-### Contract file pattern (apply to all 4)
-
-```js
-/** @typedef {{ opId: string, userId: string, targetState: string,
- *              previousState: string, issuedAt: number, timeoutId: number|null }} PendingOp */
-
-/**
- * @param {Partial<PendingOp>} input
- * @returns {PendingOp}
- */
-export function createPendingOp(input) { ... }
-
-/**
- * @param {unknown} dto
- * @returns {PendingOp}
- * @throws {TypeError} with field name on violation
- */
-export function isValidPendingOp(dto) { ... }
-```
-
-Validator rules:
-- Reject unknown keys
-- Timestamps: finite, non-negative integer
-- Id fields: non-empty string
-- Arrays default `[]`
-- Nullable fields explicit `null` (never `undefined`)
-
-### LESS state map — exact shape for `styles/tokens/_states.less`
-
-```less
-@sp-states: {
-  active:          { color: @sp-color-active,    icon: '\f06e'; shape: solid;  };
-  hidden:          { color: @sp-color-hidden,    icon: '\f070'; shape: dashed; };
-  self-muted:      { color: @sp-color-muted,     icon: '\f131'; shape: solid;  };
-  offline:         { color: @sp-color-offline,   icon: '\f00d'; shape: none;   };
-  cam-lost:        { color: @sp-color-warning,   icon: '\f03d'; shape: dashed; };
-  reconnecting:    { color: @sp-color-info,      icon: '\f021'; shape: pulse;  };
-  never-connected: { color: @sp-color-neutral,   icon: '\f068'; shape: none;   };
-  ghost:           { color: @sp-color-ghost,     icon: '\f2be'; shape: dotted; };
-  pending:         { color: @sp-color-neutral,   icon: '\f110'; shape: pulse;  };
-};
-```
-
-State colour values (from UX spec):
-
-| State | Hex | WCAG AA |
-|---|---|---|
-| `active` | `#4a9e6b` | ✅ |
-| `hidden` | `#6b7280` | ⚠️ Icon/shape only |
-| `self-muted` | `#8b92a5` | ✅ |
-| `offline` | `#4b5563` | ⚠️ Icon/shape only |
-| `cam-lost` | `#9ca3af` | ✅ |
-| `reconnecting` | `#c8982a` | ✅ |
-| `never-connected` | `#374151` | ⚠️ Icon/shape only |
-| `ghost` | `#1f2937` | ⚠️ Icon/shape only |
-
-> ⚠️ States marked "Icon/shape only" MUST NOT appear as text or small-pill foreground — colour is supplementary; icon + shape carry the primary signal (WCAG requirement).
-
-### Layer 1 SP semantic alias tokens (exact values from UX spec)
-
-```css
-:root {
-  --sp-surface:          var(--sp-theme-surface,      var(--color-bg-option,       #141618));
-  --sp-text-primary:     var(--sp-theme-text-primary, var(--color-text-primary,    #dde2e8));
-  --sp-text-secondary:   var(--sp-theme-text-muted,   var(--color-text-secondary,  #7a8390));
-  --sp-accent:           var(--sp-theme-accent,       var(--color-warm-2,          #4a9e6b));
-  --sp-focus:            var(--sp-theme-focus,        var(--color-focus-outline,   #63c287));
-  --sp-urgency-director: var(--sp-theme-urgency,      #c8982a); /* NO Foundry error/warn token */
-}
-```
-
-> ⚠️ `--sp-urgency-director` MUST NOT inherit Foundry's error/warn colours. A director cue is a deliberate stage direction, not a failure.
-
-### State token naming — three sub-tokens per state
-
-Each state provides three CSS custom properties:
-```
---sp-state-{name}-text
---sp-state-{name}-border
---sp-state-{name}-bg
-```
-
-### VisibilityBadge `:root` exception
-
-Badge (`PlayerStatusBadge`) is mounted outside the `.scrying-pool` root DOM node, directly onto Foundry's AV tile DOM. Badge state tokens MUST be declared on `:root` so they are available outside the module's root. Add a prominent comment explaining this architectural exception.
-
-### Naming conventions (enforce across all files)
-
-- JS files (classes/modules): PascalCase — `StateStore.js`, `FoundryAdapter.js`
-- Utility/helper files: camelCase — `uuid.js`
-- Contract files: kebab-case — `socket-message.js`, `pending-op.js`
-- Test files: `{SourceFile}.test.js` — `StateStore.test.js`
-- Named exports only — `export class StateStore {}`, never `export default`
-- World settings prefix: `scrying-pool.` — never `video-view-manager.X`, `sp.X`, `vvm.X`
-- Socket events prefix: `scrying-pool.` 
-- CSS prefix: `.sp-` or scoped under `.scrying-pool`
-- Console prefix: `[ScryingPool]` on ALL console calls
-- Public API returns `null` not `undefined` for "not found"
-
-### Constructor rule
-
-```js
-// ✅ constructor(adapter) { this._adapter = adapter; }
-//    init() { this._adapter.hooks.once('ready', () => this._onReady()); }
-// ❌ constructor(adapter) { adapter.hooks.once('ready', ...); }
-```
-Lifecycle registration belongs in `module.js` (owns `Hooks.once('init')` and `Hooks.once('ready')`). Individual module constructors must be side-effect free.
-
-### Test pattern — canonical mock
-
-```js
-import { createFoundryAdapterMock } from '../helpers/foundryAdapterMock.js'
-const adapter = createFoundryAdapterMock({ settings: { get: () => 'custom' } })
-```
-**No ad-hoc stubs.** All tests use `createFoundryAdapterMock` — the canonical mock factory is established in this story and reused by all subsequent tests.
-
-### Fixture pattern
-
-```js
-// All fixtures are Object.freeze'd
-export const SOCKET_PAYLOADS = Object.freeze({ ... })
-// Include negative/invalid fixtures for every validateX() rejection branch
-```
-
-### socket-payloads.js fixture shape (stub at this stage)
-
-Must include at minimum:
-- Valid intent payload (`scrying-pool.visibility.set`)
-- Valid echo payload (`scrying-pool.visibility.updated`)
-- Malformed: missing `opId`
-- Malformed: wrong enum value for state
-- Malformed: extra unknown keys
-
-### State precedence (for VisibilityManager stories — document here for context)
-
-```
-pending > cam-lost > reconnecting > offline > never-connected > self-muted > hidden > ghost > active
-```
-
-CSS never handles multi-state conflicts — VisibilityManager/RoleRenderer resolve before rendering.
-
-### module.json v14 manifest required fields
-
-```json
-{
-  "id": "video-view-manager",
-  "title": "Video View Manager (Scrying Pool)",
-  "version": "0.1.0",
-  "compatibility": { "minimum": "14", "verified": "14" },
-  "esmodules": ["module.js"],
-  "styles": ["dist/styles/scrying-pool.css"],
-  "languages": [{ "lang": "en", "name": "English", "path": "lang/en.json" }]
-}
-```
-
-> ⚠️ `version` field in `module.json` is managed by `scripts/package.mjs` at release time. Do NOT edit it manually during development.
-
-### Project Structure Notes
-
-This is story 1.1 — the project root is currently empty. Create the full directory structure from scratch:
-
-```
-video-view-manager/
-├── module.json
-├── module.js                     ← stub (Hooks.once init/ready only)
-├── package.json
-├── tsconfig.json
-├── vitest.config.js
-├── .eslintrc.js
-├── .gitignore
-├── .gitea/workflows/ci.yml
-├── scripts/package.mjs
-├── src/
-│   ├── contracts/                ← 4 contract files (full implementation)
-│   └── utils/uuid.js             ← stub (opId generation for PendingOp, later stories)
-├── styles/

-└── tests/
-    ├── helpers/foundryAdapterMock.js
-    ├── fixtures/                 ← 6 fixture files (all Object.freeze'd)
-    └── unit/contracts/           ← 4 contract test files
-```
-
-**No `src/core/`, `src/foundry/`, `src/ui/` files yet** — those are Story 1.2+. Import boundary ESLint rules must still be configured now so they catch violations as soon as those files are created.

-## Dev Agent Record
-
-### Agent Model Used
-
-Claude Sonnet 4.6 (claude-sonnet-4.6) via GitHub Copilot CLI
-
-### Debug Log References
-
-- ESLint 9.x uses flat config (`eslint.config.js`), not `.eslintrc.js` as story spec states. Used flat config with `@eslint/js`, browser globals, and FoundryVTT globals declared explicitly.
-- LESS `*/` in block comments causes ParseError — switched all LESS `/** */` comments to `//` line comments.
-- `tsconfig.json`: `moduleResolution: "node16"` requires `module: "Node16"` — changed to `moduleResolution: "bundler"` (TS 5+ only, compatible with ESNext module).
-- Contract validators: destructuring `unknown` requires intermediate `Record<string, unknown>` cast for TypeScript strict mode.
-- `scripts/package.mjs`: `catch(err)` needs `err instanceof Error ? err.message : String(err)` under strict TS.
-- Test fixture/helper files with untyped stub functions use `// @ts-nocheck` pragma — deliberate, test infrastructure only.
-- `globals` package available transitively via ESLint — used for `globals.browser` in flat config.
-
-### Completion Notes List
-
-- ✅ Task 1: `package.json` initialized, `npm install` exits 0; Node 24.14.1 / npm 11.4.0
-- ✅ Task 2: `tsconfig.json` (moduleResolution: bundler), `eslint.config.js` (flat config), `vitest.config.js`, `.gitignore`
-- ✅ Task 3: `module.json` v14 manifest with all required fields
-- ✅ Task 4: `scripts/package.mjs` release script; produces `module.zip` (14 KB) at v0.1.0
-- ✅ Task 5: `module.js` entry stub with `Hooks.once('init')` and `Hooks.once('ready')`
-- ✅ Task 6: All 4 contract files fully implemented with factory + validator; all validators reject unknown keys, throw `TypeError` with field name
-- ✅ Task 7: Full LESS token system; `npm run build` → `dist/styles/scrying-pool.css` ✅; VisibilityBadge `:root` exception documented
-- ✅ Task 8: 49 unit tests across 4 contract test files; all pass; `tests/helpers/foundryAdapterMock.js` canonical mock established
-- ✅ Task 9: `.gitea/workflows/ci.yml` — lint + typecheck + test + build on every push
-- ✅ Task 10: `lang/en.json` — valid `{}` skeleton
-- ✅ Task 11: 5 Handlebars template stubs created
-- ✅ Task 12: Full pipeline — `lint` ✅ `typecheck` ✅ `test` ✅ `build` ✅ `release` ✅
-
-**Deviations from story spec:**
-- `eslint.config.js` (flat config) used instead of `.eslintrc.js` (ESLint 9 dropped `.eslintrc.*` support)
-- `moduleResolution: "bundler"` instead of `"node16"` (node16 requires module: Node16)
-- `foundry-vtt-types` not installed — `Hooks` declared via minimal `src/types/foundry-globals.d.ts` instead

-# Blind Hunter Review Layer
-
-## ROLE
-You are **Blind Hunter** — an adversarial code reviewer. You have NO access to the project, spec, or any context. You only see the diff below.
-
-## MISSION
-Find problems. Be ruthless. Assume nothing is intentional. Look for:
-- **Security vulnerabilities** (injection, XSS, path traversal, hardcoded secrets)
-- **Bugs** (logical errors, race conditions, null dereferences)
-- **Performance issues** (N+1 queries, unnecessary computations, memory leaks)
-- **Anti-patterns** (god objects, circular dependencies, mutable globals)
-- **Code smells** (duplicate code, long methods, magic numbers)
-- **Best practice violations** (error handling, input validation, coding standards)
-- **Anything suspicious** (unusual patterns, odd dependencies, weird configurations)
-
-## OUTPUT FORMAT
-Output ONLY a Markdown list of findings. No preamble, no summary. Each finding:
-```markdown
-- **[SEVERITY]** Short title — file:line — evidence/quote from diff
-```
-Severity: CRITICAL, HIGH, MEDIUM, LOW, INFO

-# Edge Case Hunter Review Layer
-
-## ROLE
-You are **Edge Case Hunter** — a meticulous reviewer focused on boundary conditions and unusual scenarios. You have read access to the project files but ONLY for understanding context. Your primary input is the diff below.
-
-## MISSION
-Walk every branching path and boundary condition. Look for:
-- **Unchecked assumptions** (what if this is null/undefined/empty/zero?)  
-- **Off-by-one errors** (loop boundaries, array indices, string slicing)
-- **Type coercion issues** (== vs ===, truthy/falsy confusion)
-- **Concurrency problems** (race conditions, async/await mishandling)
-- **Edge input values** (empty strings, very long strings, special characters, unicode)
-- **State transitions** (what happens after error? after retry? after timeout?)
-- **Error handling gaps** (unhandled exceptions, missing error cases)
-- **API contract violations** (return types, parameter validation, side effects)
-
-## OUTPUT FORMAT  
-Output ONLY a Markdown list of findings. No preamble, no summary. Each finding:
-```markdown
-- **[SEVERITY]** Short title — file:line — edge case description + evidence
-```
-Severity: CRITICAL, HIGH, MEDIUM, LOW, INFO

+# Retrospective — Epic 1: Core Camera Visibility Control
+
+**Date:** 2026-05-22  
+**Facilitator:** Amelia (Developer)  
+**Project Lead:** Morr  
+**Status:** Complete
+
+---
+
+## Epic Summary
+
+| Metric | Value |
+|--------|-------|
+| Stories Completed | 6 / 6 (100%) |
+| Test Count at Close | 296 tests, all passing |
+| Technical Debt Items | 8 open (deferred-work.md) |
+| Major Blockers | 1 (OQ-1 WebRTC spike — resolved as css-fallback) |
+| Architecture Deviations Corrected | 3 |
+| Previous Retrospective | None (first epic) |
+
+**Stories:**
+- 1.1 — Module Scaffold, CI/CD & Design Token System ✅
+- 1.2 — WebRTC Spike — Track Disabling API Validation ✅
+- 1.3 — Data Layer — FoundryAdapter, StateStore & Socket Infrastructure ✅
+- 1.4 — Core Logic — ScryingPoolController & VisibilityManager ✅
+- 1.5 — GM Control UI — ScryingPoolStrip, ActionPopover & AV Tile Integration ✅
+- 1.6 — Player Camera Status Badge ✅
+
+---
+
+## Successes & Strengths
+
+1. **TDD discipline held across all 6 stories.** Started at 49 tests (Story 1.1), ended at 296 — every story delivered a passing pipeline with zero regressions.
+
+2. **Import boundary enforcement worked.** ESLint `import/no-restricted-paths` wired in Story 1.1 held for the full epic. Zero cross-layer violations slipped through.
+
+3. **Accessibility built into ACs, not added later.** `prefers-reduced-motion` gates, native `<dialog>` for focus trapping, `aria-live="polite"` on the VisibilityBadge — all specified upfront and delivered.
+
+4. **UI pattern reuse was excellent.** `ActionPopover` (Story 1.5) was directly reused as the pattern for `FirstEncounterPanel` and `VisibilityDetailsPanel` (Story 1.6) — zero wheel reinvention.
+
+5. **Architecture guardrails saved multiple errors.** Three corrections were caught and applied mid-story rather than shipping as bugs.
+
+6. **Morr's assessment:** Everything runs fine. Clean green on all tests.
+
+---
+
+## Challenges & Growth Areas
+
+### 1. Epic/Architecture Spec Drift (3 occurrences)
+
+Mismatches between the epics file and architecture document caught mid-story:
+- Story 1.1: `.eslintrc.js` spec vs ESLint 9 flat config (`eslint.config.js`)
+- Story 1.2: Epic path `src/adapters/foundry-adapter.js` vs architecture-canonical `src/foundry/FoundryAdapter.js`
+- Story 1.2: Setting namespace `video-view-manager.*` in spec vs correct `scrying-pool.*`
+
+**Root cause:** Architecture doc written before epics were finalized; paths/namespaces drifted.  
+**Resolution:** Dev agent caught all three. No shipped bugs, but correction cycles add overhead.
+
+### 2. Spike Story AC Format
+
+Story 1.2's ACs assumed `track-disable` would be the spike outcome. The spike proved it wasn't — `css-fallback` is the FoundryVTT v14 reality. The dev agent correctly updated test expectations, but the story file had wrong expectations going in.
+
+**Root cause:** Spike ACs written as implementation expectations, not hypothesis format.
+
+### 3. Vitest Fake Timer Nested Pattern Not Documented
+
+Story 1.6 discovered that `vi.advanceTimersByTime(N)` requires two separate advance calls when a timer callback schedules a nested timer. The first advance fires the outer timer; the second fires the inner one. This cost debugging time.
+
+**Pattern discovered:** 
+```js
+vi.advanceTimersByTime(10_001); // fires 10s collapse timeout
+vi.advanceTimersByTime(301);    // fires 300ms CSS transition replacement timer
+```
+
+### 4. Story 1.1 Review Depth
+
+The Story 1.1 code review generated 3 separate review prompt files and 7 deferred CI/CD items. While appropriate for a scaffold story, the depth felt heavy relative to the scope.
+
+---
+
+## Key Insights & Lessons
+
+1. **Spike stories need hypothesis-format ACs.** Write: "Given X, when spike runs, then outcome will be documented as one of [A/B/C]" — not pre-determined implementation expectations.
+
+2. **Vitest nested timer testing requires two-step advance.** Always use two `vi.advanceTimersByTime()` calls when the callback under test schedules a subsequent timer. Document this pattern visibly in dev notes for any story with timer-based logic.
+
+3. **Architecture doc is canonical over epics.** When epics and architecture disagree, architecture wins. Path inconsistencies should be resolved in epics review before stories are created.
+
+4. **Foundation story reviews deserve more scrutiny.** Story 1.1 review depth was appropriate; the overhead is proportional to its cross-cutting nature. Non-foundation stories can use lighter review.
+
+5. **Reuse patterns establish themselves within 1-2 stories.** ActionPopover → FirstEncounterPanel/VisibilityDetailsPanel shows that patterns spread naturally when the first implementation is clean.
+
+---
+
+## Deferred Technical Debt (from deferred-work.md)
+
+These items are tracked, not forgotten, and should be addressed in Epic 2:
+
+**HIGH PRIORITY (should fold into Story 2.1 or 2.2):**
+- [ ] Memory leak: `_revisions` Map in `ScryingPoolController.js:31` — no cleanup on user disconnect
+- [ ] Listener cleanup: `init()` socket + Hooks listeners never unregistered in `ScryingPoolController.js` and `VisibilityManager.js`
+- [ ] Echo revision validation: No guard against NaN/Infinity in `ScryingPoolController.js:164`
+
+**MEDIUM PRIORITY:**
+- [ ] Echo accepts non-finite revisions (same file, revision ?? 0 doesn't validate type)
+- [ ] CVE-2023-43645 in flat-cache-4.0.1 (needs verification — may be transitive dev dep only)
+
+**LOW PRIORITY (CI/CD, pre-existing):**
+- [ ] Missing failure notifications, missing build artifact upload, no Node matrix testing
+- [ ] Missing concurrency control, missing i18n schema validation, ubuntu-latest not pinned
+
+---
+
+## Epic 2 Preview & Readiness
+
+**Epic 2: Player Notifications & Director's Board**  
+Stories: 2.1 NotificationBus, 2.2 Director's Board Core, 2.3 Director's Board Bulk Actions
+
+**Dependencies on Epic 1 work:**
+- `ScryingPoolController.action()` + event system ✅ solid
+- `SocketHandler` echo/broadcast ✅ solid
+- `AVTileAdapter` pattern available for Director's Board card tiles ✅
+- `StateStore` visibility matrix ✅
+
+**Readiness: CLEAR TO PROCEED ✅**  
+No blockers. Recommended: fold memory leak + listener cleanup into Story 2.1 dev tasks.
+
+**Preparation notes for Story 2.1:**
+- NotificationBus introduces a 3s coalescing timer — explicitly include the vitest fake timer two-advance pattern in dev notes
+- Include deferred debt items (_revisions cleanup, listener unregistration) as Story 2.1 technical tasks
+- NotificationBus subscribes to ScryingPoolController events — the listener cleanup debt becomes higher priority once another subscriber is added
+
+---
+
+## Action Items
+
+### Technical (carry into Epic 2)
+
+| Item | Owner | Priority | Target Story |
+|------|-------|----------|--------------|
+| Fix `_revisions` Map leak (`ScryingPoolController.js:31`) | Dev | High | 2.1 or 2.2 |
+| Add listener cleanup to ScryingPoolController + VisibilityManager | Dev | High | 2.1 or 2.2 |
+| Add echo revision type validation (reject NaN/Infinity) | Dev | Medium | 2.1 or 2.2 |
+| Verify CVE-2023-43645 flat-cache scope | Dev | Low | Backlog |
+
+### Process Improvements
+
+| Item | Action |
+|------|--------|
+| Spec drift | Review epic paths/namespaces against architecture doc before story creation |
+| Spike ACs | Write spike ACs as hypothesis format, not expected outcomes |
+| Fake timer pattern | Add vitest nested timer two-advance pattern to story dev notes whenever coalescing timers are involved |
+
+---
+
+## Next Steps
+
+1. ✅ Retrospective saved
+2. ✅ `epic-1-retrospective` marked `done` in sprint-status.yaml
+3. → Create Story 2.1 (NotificationBus & Notification Verbosity) using `bmad-create-story`
+4. → Fold deferred debt items into Story 2.1 dev tasks
+

+
+*Amelia (Developer): "Great session, Morr. Epic 1 delivered a solid, tested foundation. Epic 2 is clear to go."*
+
+*Winston (System Architect): "The architecture held. Import boundaries, constructor rules, token system — all intact."*
+
+*Sally (UX Designer): "Accessibility-first delivered. Epic 2 has its own UX challenges with the Director's Board — looking forward to it."*

+
+## Challenges & Growth Areas
+
+### ⚠️ Key Challenges
+
+1. **Cross-Story Interface Mismatches**
+   - **Issue:** Story 2.2 implemented `_dispatchToggle()` with object parameter `{userId, targetState}` but ScryingPoolController.action() expects positional args `(source, participantId, targetState, opId, baseRevision)`
+   - **Resolution:** Fixed in Story 2.3 Task 1, but cost development time
+   - **Root Cause:** Insufficient integration testing between stories
+   - **Pattern:** 1 story had cross-story interface issues
+
+2. **Event Listener Lifecycle Management**
+   - **Issue:** Memory leak fixes were deferred from Epic 1 and had to be addressed in Epic 2
+   - **Manifestations:**
+     - `_revisions` Map leak in ScryingPoolController
+     - Missing `teardown()` methods in multiple classes
+     - DOM listener cleanup on close/reopen cycles
+   - **Resolution:** Story 2.1 Tasks 4.1-4.3, Story 2.3 various fixes
+   - **Pattern:** 3 out of 3 stories had to add cleanup/teardown logic
+
+3. **Race Conditions in Bulk Operations**
+   - **Issue:** Story 2.3 bulk actions (showAll, hideAll, spotlight) had race conditions in state capture
+   - **Manifestations:** Inconsistent snapshots when user states changed mid-operation
+   - **Resolution:** Atomic state capture before iteration
+   - **Pattern:** All bulk operations now capture complete state snapshot first
+
+4. **Sidebar Button API Uncertainty**
+   - **Issue:** FoundryVTT v14 `getSceneControlButtons` hook API was uncertain
+   - **Resolution:** Implemented with safe optional chaining, added fallback CTA button in ScryingPoolStrip
+   - **Pattern:** Defensive coding for uncertain APIs
+
+---
+
+## Patterns Identified
+
+### ✅ Positive Patterns (Repeat These)
+
+1. **Deferred Debt Folding**
+   - Story 2.1 proactively addressed Epic 1 deferred items
+   - Pattern: Address deferred work early in the next epic
+   - **Recommendation:** Continue this pattern for Epic 3
+
+2. **Utility Function Extraction**
+   - Story 2.3 created `src/utils/boardUtils.js` for shared context building
+   - Pattern: Extract shared logic into utility modules
+   - **Recommendation:** Apply this pattern more aggressively
+
+3. **State Machine Patterns**
+   - Undo/Restore state machine with `_undoSnapshot` and `_spotlightSnapshot`
+   - Pattern: Clear state transitions with mutual exclusion
+   - **Recommendation:** Document this pattern for reuse
+
+4. **Bulk Operation Patterns**
+   - Atomic state capture before iteration
+   - Ghost state exclusion checks
+   - Pending operation guards
+   - Pattern: Robust bulk operation handling
+   - **Recommendation:** Create reusable bulk operation helper
+
+### ⚠️ Negative Patterns (Avoid These)
+
+1. **Insufficient Cross-Story Testing**
+   - Interface mismatches between stories
+   - Pattern: Test story interfaces against their dependencies
+   - **Recommendation:** Add integration test step to story creation checklist
+
+2. **Late Lifecycle Management**
+   - `teardown()` methods added as fixes rather than designed in
+   - Pattern: Event cleanup as afterthought
+   - **Recommendation:** Include teardown in initial class design template

+# Edge Case Hunter Review Prompt - Story 1-5 Group 1 (Core Logic)
+
+**Story:** 1-5-gm-control-ui-scryingpoolstrip-actionpopover-and-av-tile-integration  
+**Group:** Core Logic (Group 1 of 4)  
+**Files:** ScryingPoolController.js, VisibilityManager.js, and their tests  
+**Diff lines:** 804  
+**Project path:** /home/morr/work/foundryvtt/video-view-manager
+
+---
+
+## YOUR ROLE: Edge Case Hunter
+
+You are an **Edge Case Hunter** code reviewer. You receive the diff below AND read access to the project repository at `/home/morr/work/foundryvtt/video-view-manager`. Your job is to find edge cases, boundary conditions, and unusual scenarios that the code doesn't handle properly.
+
+### Rules:
+- You have read access to the project directory
+- You have access to the diff below
+- You have NO access to the spec file (blind to requirements)
+- You MUST find at least 5 edge case issues
+- Focus on: null/undefined handling, empty collections, concurrent access, extreme values, error paths, timing issues, state transitions
+
+### Method:
+1. Read the diff carefully
+2. Explore the project codebase to understand the broader context
+3. Walk every branching path in the code
+4. Check boundary conditions for all inputs and loops
+5. Identify unhandled edge cases
+
+### Output Format:
+Output findings as a Markdown list. Each finding:
+```markdown
+- **EC-XX: [One-line title]** — [Code location] — [Edge case scenario] — [Impact]
+```
+
+Classify by type:
+- **EC-NULL**: Missing null/undefined checks
+- **EC-BOUNDARY**: Off-by-one, empty collections, extreme values
+- **EC-CONCURRENCY**: Race conditions, async issues
+- **EC-STATE**: Invalid state transitions, inconsistent state
+- **EC-ERROR**: Unhandled exceptions, error swallowing
+- **EC-TIMING**: Timeout issues, ordering problems

+# Code Review - Story 1.5 Group 1 (Core Logic)
+
+**Generated:** 2026-05-22  
+**Story:** 1-5-gm-control-ui-scryingpoolstrip-actionpopover-and-av-tile-integration  
+**Review Group:** 1 of 4 (Core Logic)  
+**Status:** Awaiting parallel reviewer execution
+
+---
+
+## REVIEW WORKFLOW
+
+This directory contains prompt files for parallel code review layers. Each layer must be executed in a **separate session** (ideally with a different LLM model) to ensure independent analysis.
+
+### Review Layers
+
+1. **🔴 Blind Hunter** (`01-blind-hunter-prompt.md`)
+   - **Skill:** `bmad-review-adversarial-general`
+   - **Input:** Diff only (no spec, no context, no project access)
+   - **Focus:** Security issues, bugs, anti-patterns, performance problems
+   - **Output:** Adversarial findings (minimum 5)
+
+2. **🟡 Edge Case Hunter** (`02-edge-case-hunter-prompt.md`)
+   - **Skill:** `bmad-review-edge-case-hunter`
+   - **Input:** Diff + project read access
+   - **Focus:** Edge cases, boundary conditions, null handling, race conditions
+   - **Output:** Edge case findings (minimum 5)
+
+3. **🟢 Acceptance Auditor** (`03-acceptance-auditor-prompt.md`)
+   - **Input:** Diff + spec file + context docs + project read access
+   - **Focus:** AC compliance, spec violations, missing implementation
+   - **Output:** Acceptance audit findings
+
+---

+## FILES IN THIS GROUP
+
+### New Files (4)
+- `src/core/ScryingPoolController.js` (181 lines)
+- `src/core/VisibilityManager.js` (104 lines)
+- `tests/unit/core/ScryingPoolController.test.js` (277 lines)
+- `tests/unit/core/VisibilityManager.test.js` (218 lines)
+
+### Diff Size
+- Total: **804 lines** (under 3000 line threshold ✓)
+
+---
+
+## INSTRUCTIONS FOR REVIEWERS
+
+### For Each Layer:
+1. Open the prompt file for that layer
+2. Read the entire file carefully
+3. Execute the review as described in the role section
+4. Return findings in the specified format
+5. Save findings to a separate file (e.g., `findings-blind-hunter.md`)
+
+### After All Layers Complete:
+1. Collect all findings files
+2. Return to this workflow at Step 3 (Triage)
+3. Paste all findings for consolidated triage
+
+---
+
+## REMINDER
+
+- All layers run **in parallel** — do not wait for one to finish before starting another
+- Each layer must use a **different session** to maintain independence
+- All findings are consolidated in Step 3 (Triage) before final presentation
+
+---
+
+## NEXT STEPS
+
+After generating findings from all three layers:
+1. Proceed to `step-03-triage.md` in the bmad-code-review workflow
+2. Triage and deduplicate findings
+3. Present consolidated results
