+## 📋 Story Requirements
+
+### User Story
+
+**As a** player,
+**I want to** choose a custom image to display when my camera feed is unavailable,
+**So that** my on-screen presence is represented the way I prefer even when my camera isn't working.
+
+### Persona Alignment
+
+- **Primary:** Elena (Casual Player) - Wants to maintain a consistent on-screen identity
+- **Primary:** All Players - Need control over their visual representation
+- **Secondary:** GM (Marcus, Jake) - Benefits from players having consistent representation
+
+### Acceptance Criteria (BDD Format)
+
+#### AC-1: Portrait Fallback Section in Privacy Panel
+**Given** the Player Privacy Panel is open
+**When** a player views it for their own user
+**Then** a "Portrait Fallback" section is visible
+**And** it contains a file picker button labeled "Choose Image" or similar
+**And** it contains a preview of the current fallback image
+**And** it contains a "Remove custom image" option if a custom image is set
+
+#### AC-2: File Picker Accepts Supported Formats
+**Given** the player clicks "Choose Image" in the Portrait Fallback section
+**When** they select a PNG, JPG, WEBP, or static GIF file
+**Then** the file is accepted
+**And** the preview updates to display the selected image
+**And** the image is saved as the custom Portrait Fallback
+
+#### AC-3: Unsupported Formats Rejected
+**Given** the player attempts to select a file with an unsupported format (e.g., `.svg`, `.mp4`, `.pdf`)
+**When** the file picker attempts to accept it
+**Then** an error message shows: "Unsupported format. Please use PNG, JPG, WEBP, or static GIF."
+**And** the previous fallback image remains unchanged
+**And** no custom Portrait Fallback is set
+
+#### AC-4: Custom Fallback Displayed When Camera Unavailable
+**Given** a player has set a custom Portrait Fallback image
+**When** their participant state is `never-connected`
+**Then** the custom fallback image is displayed at AV tile dimensions
+**And** it renders at the same size as a live camera feed tile
+**And** there is no layout shift
+
+#### AC-5: Custom Fallback Displayed When Camera Lost
+**Given** a player has set a custom Portrait Fallback image
+**When** their participant state is `cam-lost`
+**Then** the custom fallback image is displayed at AV tile dimensions
+**And** it renders at the same size as a live camera feed tile
+**And** there is no layout shift
+
+#### AC-6: Fallback to FoundryVTT Avatar
+**Given** a player has NOT set a custom Portrait Fallback image
+**When** their participant state requires a fallback (`never-connected` or `cam-lost`)
+**Then** the module uses the FoundryVTT user avatar
+**And** if no FoundryVTT avatar exists, the system placeholder is used
+
+#### AC-7: Fallback Persistence Across Sessions
+**Given** a player has set a custom Portrait Fallback image
+**When** they refresh the page or reconnect to the session
+**Then** the custom fallback image is still displayed when needed
+**And** it persists across all sessions in the same world
+
+#### AC-8: Remove Custom Image
+**Given** a player has a custom Portrait Fallback image set
+**When** they click "Remove custom image" and confirm
+**Then** the custom image is removed
+**And** the fallback reverts to the FoundryVTT user avatar (or system placeholder)
+**And** the preview in the Privacy Panel updates accordingly
+
+#### AC-9: Image Rendering at Correct Dimensions
+**Given** any fallback image is displayed
+**When** it renders in an AV tile
+**Then** it displays at the same dimensions as a live camera feed
+**And** the aspect ratio is maintained
+**And** there is no distortion or stretching
+
+### Functional Requirements Covered
+
+- **FR-8:** Portrait Fallback displayed when Participant has no camera (`never-connected`) or enters `cam-lost` state; default is FoundryVTT user avatar falling back to system placeholder; renders at same dimensions as a live camera-feed tile; Participants can set custom Portrait Fallback via Player Privacy Panel (FR-26).
+- **FR-26:** Custom Portrait Fallback settable via file picker in Player Privacy Panel; accepted formats: PNG, JPG, WEBP, static GIF; falls back to FoundryVTT user avatar, then to system placeholder if no avatar exists.
+
+### Success Criteria
+
+- [ ] All 9 acceptance criteria pass manual testing
+- [ ] All unit tests pass (target: +15-20 new tests for PortraitFallbackManager)
+- [ ] `npm run lint` exits 0 (ESLint import boundaries enforced)
+- [ ] `npm run typecheck` exits 0 (strict JSDoc compliance)
+- [ ] Code review passes with no critical findings
+- [ ] Integration test: Player sets custom image → verify display in `never-connected` state → verify display in `cam-lost` state → verify persistence → verify remove functionality

+
+## 📝 Tasks / Subtasks
+
+### Task 1: Extend Privacy Settings Contract
+
+**Files:** `src/contracts/privacy-settings.js`
+
+**Subtasks:**
+- [x] 1.1: Add `customPortraitFallback` key to `PRIVACY_SETTINGS_DEFAULT`
+  - Type: `string | null` (null = no custom image)
+  - Default: `null`
+- [x] 1.2: Update `PRIVACY_SETTING_KEYS` to include `customPortraitFallback`
+- [x] 1.3: Update `isValidPrivacySettings()` validator to handle string or null
+- [x] 1.4: Update `createPrivacySettings()` factory to handle the new key
+- [x] 1.5: Add `VALID_PORTRAIT_FORMATS` constant: `['image/png', 'image/jpeg', 'image/webp', 'image/gif']`
+- [x] 1.6: Add `validatePortraitDataURL(dataURL)` function to validate format from DataURL
+- [x] 1.7: Export `MAX_PORTRAIT_SIZE` constant (5MB recommended)
+
+**Acceptance Criteria:** AC-2, AC-3, AC-6
+
+**Completion Notes:**
+- All 73 tests pass for privacy-settings contract
+- Backward compatibility maintained - old settings without customPortraitFallback still validate
+- DataURL validation supports PNG, JPEG, WEBP, GIF formats
+- Size limit set to 5MB (note: FoundryVTT user flags typically have ~50KB limit)
+
+**Dev Notes:**
+- Store portrait as DataURL string in user flags (persistent, portable)
+- DataURL format: `data:image/png;base64,...` or similar
+- Validation must check both MIME type and actual file content
+- Keep backward compatibility with existing settings
+
+---
+
+### Task 2: Extend PlayerPrivacyManager for Portrait Operations
+
+**Files:** `src/core/PlayerPrivacyManager.js`, `tests/unit/core/PlayerPrivacyManager.test.js`
+
+**Subtasks:**
+- [x] 2.1: Add `setPortraitFallback(userId, dataURL)` method
+  - Validates dataURL format using `validatePortraitDataURL()`
+  - Calls `adapter.users.setFlag(userId, 'video-view-manager', 'customPortraitFallback', dataURL)`
+  - Emits change event to subscribers
+- [x] 2.2: Add `getPortraitFallback(userId)` method
+  - Returns DataURL string or null if not set
+  - Falls back to null (FoundryVTT avatar will be used by caller)
+- [x] 2.3: Add `removePortraitFallback(userId)` method
+  - Removes the custom Portrait Fallback flag
+  - Calls `adapter.users.unsetFlag(userId, 'video-view-manager', 'customPortraitFallback')`
+  - Emits change event to subscribers
+- [x] 2.4: Update `getSettings()` to include `customPortraitFallback` in returned object
+- [x] 2.5: Update `setSetting()` to reject `customPortraitFallback` (use dedicated method)
+- [x] 2.6: Add `getPortraitFallbackDataURL(userId)` convenience method
+  - Returns the DataURL directly (for rendering)
+  - Returns null if no custom fallback
+- [x] 2.7: Update existing tests to account for new key in settings shape
+- [x] 2.8: Add new tests for portrait methods (16 new tests added)
+
+**Acceptance Criteria:** AC-2, AC-3, AC-4, AC-5, AC-6, AC-7, AC-8, AC-9
+
+**Completion Notes:**
+- All 50 PlayerPrivacyManager tests pass (34 existing + 16 new)
+- Portrait methods follow the same pattern as existing boolean setting methods
+- Change events emitted for portrait changes use the same subscriber mechanism
+- File size validation note: MAX_PORTRAIT_SIZE is 5MB but FoundryVTT user flags typically have ~50KB limit
+
+**Dev Notes:**
+- User flags have a size limit in FoundryVTT (typically 10KB-100KB depending on server config)
+- For larger images, consider storing in world settings with a unique key per user
+- For v1.0, use DataURL with user flag storage (simplest approach)
+- If DataURL exceeds flag size limit, document the limitation and recommend image optimization
+- **Architecture Decision:** Store portrait as DataURL in user flag for v1.0
+  - Rationale: Simplest approach, no additional infrastructure needed
+  - Limitation: FoundryVTT user flag size limit (~50KB typical)
+  - Recommendation: Players should use optimized images (< 50KB)
+
+---
+
+### Task 3: Create PortraitFallbackHandler Core Logic
+
+**Files:** `src/core/PortraitFallbackHandler.js`, `tests/unit/core/PortraitFallbackHandler.test.js`, `tests/helpers/playerPrivacyManagerMock.js`
+
+**Subtasks:**
+- [x] 3.1: Create `PortraitFallbackHandler` class with constructor `(adapter, playerPrivacyManager)`
+  - Constructor receives FoundryAdapter for FoundryVTT avatar access
+  - Constructor receives PlayerPrivacyManager for custom portrait access
+  - No direct `game.*` access (DI enforced)
+- [x] 3.2: Implement `getFallbackImageURL(userId)` method
+  - Returns custom Portrait Fallback DataURL if set (from PlayerPrivacyManager)
+  - Returns FoundryVTT user avatar URL if no custom fallback
+  - Returns system placeholder URL if no avatar exists
+  - Returns null if user doesn't exist
+- [x] 3.3: Implement `getFallbackImageElement(userId)` method
+  - Creates an `<img>` element for the fallback image
+  - Sets appropriate src, alt text, and dimensions
+  - Returns the DOM element ready for mounting
+- [x] 3.4: Implement `validatePortraitFile(file)` static method
+  - Accepts File object from file picker
+  - Validates file type against `VALID_PORTRAIT_FORMATS`
+  - Validates file size against `MAX_PORTRAIT_SIZE`
+  - Returns { valid: boolean, error?: string }
+- [x] 3.5: Implement `fileToDataURL(file)` static method
+  - Converts File to DataURL using FileReader API
+  - Returns Promise<string> with the DataURL
+  - Handles errors gracefully
+- [x] 3.6: Add event emission for fallback changes
+  - Implemented `onPortraitChange(callback)` subscription pattern
+  - Implemented `_notifyPortraitChange()` for event emission
+  - Includes userId, newValue, and previousValue in event data
+- [x] 3.7: Write comprehensive tests (26 new tests)
+  - 26 tests covering all methods and edge cases
+  - All tests passing
+
+**Acceptance Criteria:** AC-2, AC-3, AC-4, AC-5, AC-6, AC-9
+
+**Dev Notes:**
+- FoundryVTT avatar access: `game.users.get(userId)?.avatar` or `game.user.avatar` for current user
+- System placeholder: Use FoundryVTT default avatar path or module-provided placeholder
+- Image dimensions: Should match AV tile dimensions (from architecture/UX specs)
+- FileReader API is async but works in FoundryVTT context
+- Handle file picker cancellation gracefully
+
+---
+
+### Task 4: Extend PlayerPrivacyPanel UI for Portrait Selection
+
+**Files:** `src/ui/player/PlayerPrivacyPanel.js`, `templates/player-privacy-panel.hbs`, `styles/components/_player-privacy-panel.less`
+
+**Subtasks:**
+- [x] 4.1: Add portrait fallback section to `player-privacy-panel.hbs`
+- [x] 4.2: Update `_prepareContext()` in PlayerPrivacyPanel
+- [x] 4.3: Add file picker handler in `_onRender()`
+- [x] 4.4: Implement `_onFileSelected(event)` method
+- [x] 4.5: Implement `_onRemovePortrait()` method
+- [x] 4.6: Update `_onClose()` to clean up file input event listeners
+- [x] 4.7: Add CSS styles for portrait section in `_player-privacy-panel.less`
+
+**Acceptance Criteria:** AC-1, AC-2, AC-3, AC-4, AC-5, AC-6, AC-7, AC-8, AC-9
+
+**Dev Notes:**
+- Preview should show current custom portrait OR current FoundryVTT avatar
+- File input accept attribute: `.png,.jpg,.jpeg,.webp,.gif`
+- Image preview dimensions: 100x100px or similar (match AV tile avatar size)
+- Use SP token system for colors and spacing
+- Preview container should have border to indicate it's interactive
+- Loading state for file processing (spinner or disabled state)
+
+---
+
+### Task 5: Update RoleRenderer for Custom Portrait Integration
+
+**Files:** `src/ui/RoleRenderer.js`, `src/ui/shared/AVTileAdapter.js`
+
+**Subtasks:**
+- [x] 5.1: Update constructor to accept `portraitFallbackHandler` parameter
+- [x] 5.2: Update `_applyAVTileState()` method for camera-absent states
+- [x] 5.3: Update module.js initialization to pass portraitFallbackHandler
+- [x] 5.4: Update tests for RoleRenderer to account for portrait handler
+
+**Acceptance Criteria:** AC-4, AC-5, AC-6, AC-9
+
+**Dev Notes:**
+- The fallback element should still have class `sp-portrait-fallback` for CSS targeting
+- The fallback element should still have `data-sp-role="portrait-fallback"` for data attributes
+- Image element should be wrapped or have appropriate attributes for accessibility
+- Maintain backward compatibility: if portraitFallbackHandler not provided, use existing behavior
+
+---
+
+### Task 6: Add Localization Strings
+
+**Files:** `lang/en.json`
+
+**Subtasks:**
+- [x] 6.1: Add Portrait Fallback section strings
+
+**Acceptance Criteria:** AC-1, AC-2, AC-3, AC-8
+
+**Dev Notes:**
+- All strings under `SCRYING_POOL.PrivacyPanel` namespace for consistency
+- Use plain language per NFR-6
+- Keep technical terms out of player-facing text
+- {maxSize} placeholder for dynamic size limit display
+
+---
+
+## 🎯 Developer Context
+
+### Epic Context
+
+**Epic 4: Player Privacy Panel** delivers the consent and privacy layer for all future automation features. Story 4.1 implemented the foundational Player Privacy Panel with opt-in controls for Reaction Cam and HP-Reactive Cam Styling. **Story 4.2 completes the privacy panel by adding Custom Portrait Fallback selection**, fulfilling FR-8 and FR-26.
+
+**Business Value:** Players need control over their visual representation when their camera is unavailable. This ensures a consistent on-screen presence and improves the player experience. Without custom portrait support, players with camera issues would see a generic placeholder, reducing immersion and personal expression.
+
+**Dependencies:**
+- Epic 1 (Core Camera Visibility Control) - COMPLETE
+- Epic 2 (Player Notifications & Director's Board) - COMPLETE
+- Epic 3 (Scene-Aware Camera Automation) - COMPLETE
+- Story 4.1 (Player Privacy Panel & Automation Opt-ins) - COMPLETE
+- FoundryAdapter user flag methods (from Story 4.1)
+- PlayerPrivacyManager (from Story 4.1)
+- RoleRenderer and AVTileAdapter (from Epic 1)
+- No external dependencies required
+
+**Blockers:** None identified
+
+**Cross-Story Context from Story 4.1:**
+1. **User flag storage pattern established** - Privacy settings stored as `game.user.setFlag('video-view-manager', key, value)`
+2. **PlayerPrivacyManager pattern** - Core manager class with DI, event emission, validation
+3. **PlayerPrivacyPanel UI pattern** - ApplicationV2 + Handlebars + LESS, read-only mode for GM
+4. **Import boundaries** - Core only from contracts/utils; UI from core/foundry/contracts
+5. **Testing approach** - Vitest with happy-dom, mock FoundryAdapter, TDD
+
+---
+
+### Previous Story Intelligence (Story 4.1)
+
+**Learnings from Story 4.1 (Player Privacy Panel & Automation Opt-ins):**
+1. **Contract validation is critical** - `isValidPrivacySettings()` caught type issues early in development
+2. **User flags work well for client-local data** - No socket broadcasting needed; each client reads its own data
+3. **Read-only mode implementation** - Simple comparison of `targetUserId !== currentUserId` effectively disables editing
+4. **FoundryAdapter extension pattern** - Adding user flag methods to adapter provided clean DI layer for testing
+5. **ApplicationV2 pattern** - Using conditional `_AppBase` allows testing in non-Foundry environments
+6. **Localization string organization** - Grouping by component/feature made maintenance easier
+7. **Event emission for UI updates** - Subscription pattern worked well for reactivity
+
+**Code Patterns to Reuse from Story 4.1:**
+- Constructor dependency injection for testability (PlayerPrivacyManager)
+- JSDoc on all exported symbols (enforced by ESLint)
+- Private methods prefixed with `_`
+- Error handling with descriptive messages
+- Type validation at boundaries via contract validators
+- Event emission for UI updates (subscription pattern)
+- Conditional base class for test environment compatibility
+
+**Files Created in Story 4.1:**
+- `src/contracts/privacy-settings.js` - Contract with validator
+- `src/core/PlayerPrivacyManager.js` - Core logic with validation
+- `src/ui/player/PlayerPrivacyPanel.js` - ApplicationV2 dialog
+- `src/ui/gm/GMPlayerPrivacySelector.js` - GM selector dialog
+- `src/ui/player/PlayerPrivacyPanelMenu.js` - Settings menu wrapper
+- `templates/player-privacy-panel.hbs` - Handlebars template
+- `styles/components/_player-privacy-panel.less` - LESS styles
+- `src/foundry/FoundryAdapter.js` - Extended with user flag methods
+- `module.js` - Registered settings menu
+- `lang/en.json` - Added all localization strings
+
+**Problems Encountered & Solutions in Story 4.1:**
+- **XSS vulnerability in HTML** - Unescaped user input; Fixed by proper escaping in templates
+- **Static dependency null checks** - Missing init() calls; Fixed by adding null checks and proper initialization
+- **Settings namespace mismatch** - Used 'video-view-manager' instead of 'scrying-pool'; Fixed to use consistent namespace
+- **Event listener leaks** - Duplicate listeners on re-render; Fixed by proper cleanup in _onClose()
+- **Global state anti-pattern** - Static _adapter in components; Fixed by passing dependencies through constructors
+- **Race condition in menu registration** - Menu registered before DI init; Fixed by proper initialization order
+- **Inconsistent FoundryAdapter behavior** - getFlagModule/setFlagModule had bugs; Fixed with correct user access pattern
+
+**Key Insights for Story 4.2:**
+- Follow the same DI pattern established in Story 4.1
+- Use user flags for storage (no socket needed)
+- Extend existing contracts rather than creating new ones where possible
+- Add new functionality to existing managers when appropriate
+- Ensure all FoundryAdapter dependencies are properly mocked in tests
+
+---
+
+### Architecture Compliance
+
+**Technical Stack (Same as Story 4.1):**
+- Vanilla JavaScript ES2022+ with native ESM
+- LESS 4.6.4 → CSS via chokidar watch
+- Handlebars `.hbs` templates (ApplicationV2 PARTS)
+- No external UI libraries
+- No socketlib
+- Font Awesome 6 and Foundry CSS custom properties only
+
+**Code Structure Rules:**
+- All source files in `src/` directory
+- Import boundaries enforced by ESLint `import/no-restricted-paths`
+- Contract files in `src/contracts/` define canonical data shapes
+- Core logic in `src/core/` (testable, zero `game.*` access)
+- Foundry adapter layer in `src/foundry/`
+- UI components in `src/ui/` (player/ subdirectory for player-facing)
+
+**Import Restrictions (Enforced by ESLint):**
+- `src/contracts/` - May import nothing (pure data)
+- `src/utils/` - May only import from `src/contracts/`
+- `src/core/` - May only import from `src/contracts/`, `src/utils/`
+- `src/foundry/` - May import from anywhere (adapter layer)
+- `src/ui/` - May import from `src/core/`, `src/foundry/`, `src/contracts/`
+
+**This Story's Import Plan:**
+- `privacy-settings.js` (`src/contracts/`) → extend existing contract (no new imports)
+- `PlayerPrivacyManager` (`src/core/`) → extend with portrait methods; imports from `src/contracts/`
+- `PortraitFallbackHandler` (`src/core/`) → NEW; imports from `src/contracts/`, `src/utils/`
+- `PlayerPrivacyPanel` (`src/ui/player/`) → extend existing; will import `PortraitFallbackHandler` from `src/core/`
+- `RoleRenderer` (`src/ui/`) → modify to import `PortraitFallbackHandler` from `src/core/`
+- `FoundryAdapter` (`src/foundry/`) → may need portrait access methods
+
+**Architecture Decisions to Follow:**
+- **Dependency Injection:** All Foundry API dependencies constructor-injected via FoundryAdapter
+- **Side-Effect-Free Constructors:** No hook registration in constructors; use `init()` for setup
+- **Role-Differentiated Rendering:** Player and GM UIs are separate component trees
+- **State Authority:** PlayerPrivacyManager owns privacy settings; PortraitFallbackHandler owns portrait logic
+- **Persistence:** User flags for portrait settings (world-level, user-scoped)
+- **Event Pattern:** Use subscription/emission pattern for UI updates
+
+---
+
+### Critical Implementation Requirements
+
+**1. Portrait Storage Strategy:**
+```javascript
+// For v1.0: Store as DataURL in user flag
+// Pros: Simple, no additional infrastructure
+// Cons: Limited by FoundryVTT user flag size (~50KB typical)
+// Recommendation: Document size limitation, suggest image optimization
+
+game.user.setFlag('video-view-manager', 'customPortraitFallback', dataURL);
+game.user.getFlag('video-view-manager', 'customPortraitFallback');
+```
+
+**2. File Validation Pattern:**
+```javascript
+const VALID_PORTRAIT_FORMATS = ['image/png', 'image/jpeg', 'image/webp', 'image/gif'];
+const MAX_PORTRAIT_SIZE = 5 * 1024 * 1024; // 5MB
+
+function validatePortraitFile(file) {
+  // Check MIME type
+  if (!VALID_PORTRAIT_FORMATS.includes(file.type)) {
+    return { valid: false, error: 'Unsupported format' };
+  }
+  
+  // Check file size
+  if (file.size > MAX_PORTRAIT_SIZE) {
+    return { valid: false, error: 'Image too large' };
+  }
+  
+  return { valid: true };
+}
+```
+
+**3. Portrait Fallback Resolution:**
+```javascript
+// Priority order:
+// 1. Custom Portrait Fallback (from user flag)
+// 2. FoundryVTT user avatar
+// 3. System placeholder
+function getFallbackImageURL(userId) {
+  const custom = playerPrivacyManager.getPortraitFallbackDataURL(userId);
+  if (custom) return custom;
+  
+  const user = adapter.users.get(userId);
+  if (user?.avatar) return user.avatar;
+  
+  return DEFAULT_PLACEHOLDER_URL;
+}
+```
+
+**4. RoleRenderer Integration:**
+```javascript
+// In _applyAVTileState when CAMERA_ABSENT
+if (CAMERA_ABSENT) {
+  const portraitElement = portraitFallbackHandler.getFallbackImageElement(userId);
+  this._avTileAdapter.mount(userId, portraitElement);
+}
+```
+
+**5. File Picker Pattern:**
+```javascript
+// In _onRender()
+const fileInput = document.createElement('input');
+fileInput.type = 'file';
+fileInput.accept = '.png,.jpg,.jpeg,.webp,.gif';
+fileInput.style.display = 'none';
+fileInput.addEventListener('change', (e) => this._onFileSelected(e));
+this._fileInput = fileInput;
+document.body.appendChild(fileInput);
+
+// In _onClose()
+if (this._fileInput) {
+  this._fileInput.remove();
+  this._fileInput = null;
+}
+
+// In button click handler
+this._fileInput.click();
+```
+
+---
+
+### Library & Framework Requirements
+
+**Existing Libraries Used:**
+- FoundryVTT v14 native APIs: `game.user.setFlag`, `game.user.getFlag`, `game.users.get()`
+- Native ES modules
+- Handlebars templates
+- LESS for CSS
+- FileReader API for converting files to DataURLs
+
+**No New Dependencies Required**
+- All functionality uses existing browser and FoundryVTT APIs
+- File operations use native FileReader API
+- No external libraries needed for file handling
+
+---
+
+### File Structure Requirements
+
+**New Files to Create:**
+```
+src/
+├── core/
+│   └── PortraitFallbackHandler.js         # NEW - Core portrait fallback logic
+ tests/
+└── unit/
+    └── core/
+        └── PortraitFallbackHandler.test.js # NEW - Unit tests for handler
+```

+- Create portraitFallbackHandler instance
+- Pass to RoleRenderer
+- Pass to PlayerPrivacyPanel (or make accessible)
+
+---
+

+- Test both happy path and error cases
+- Aim for 80%+ coverage on new code
+
+---
+
+### Git Intelligence Summary
+
+**Recent Commit Pattern (from Story 4.1):**
+- Feature implemented in focused commits
+- Tests written alongside implementation (TDD approach)
+- Contracts validated before implementation
+- ESLint and typecheck passing before merge
+- 35+ unit tests for PlayerPrivacyManager
+
+**Files Modified in Story 4.1:**
+- Added: `src/contracts/privacy-settings.js`, `src/core/PlayerPrivacyManager.js`
+- Added: `src/ui/player/PlayerPrivacyPanel.js`, `src/ui/gm/GMPlayerPrivacySelector.js`
+- Added: `src/ui/player/PlayerPrivacyPanelMenu.js`
+- Added: Templates and styles for privacy panel
+- Modified: `src/foundry/FoundryAdapter.js`, `module.js`
+- Modified: `lang/en.json`, various UI files
+- Tests added: 35+ unit tests
+
+**Key Insight for Story 4.2:**
+- Follow the same pattern: contracts first, then core logic, then UI, then integration
+- Extend existing files where possible (privacy-settings.js, PlayerPrivacyManager)
+- Create new files only when necessary (PortraitFallbackHandler)
+- Ensure all tests pass and lint/typecheck are clean

+
+### Latest Technical Specifics
+
+**Portrait Storage Decision for v1.0:**
+- **Approach:** DataURL in user flag
+- **Rationale:**
+  - Simple implementation with no new infrastructure
+  - User flags are world-persistent and user-scoped
+  - No socket broadcasting needed (client-local read)
+  - Compatible with existing PlayerPrivacyManager pattern
+- **Limitation:** FoundryVTT user flag size limit (~50KB typical)
+- **Mitigation:** Document limitation; recommend optimized images; provide clear error messages
+- **Future:** Could migrate to world settings with unique keys if larger images needed
+
+**Supported Image Formats:**
+- PNG (`image/png`) - Lossless, supports transparency
+- JPEG/JPG (`image/jpeg`) - Smaller file size, no transparency
+- WEBP (`image/webp`) - Modern format, good compression, supports transparency
+- GIF (`image/gif`) - Static only (animated GIFs not supported per FR-26)
+
+**File Size Limit:**
+- `MAX_PORTRAIT_SIZE`: 5MB (5 * 1024 * 1024 bytes)
+- This is higher than FoundryVTT's typical user flag limit to allow for validation before storage
+- Actual storage may fail if image exceeds FoundryVTT's limit
+- Provide clear error message if storage fails
+
+**Image Dimensions:**
+- AV tile dimensions: From UX-DR4, ParticipantAvatar is 44x44px container with 32px rounded avatar
+- Portrait fallback should match AV tile dimensions
+- Recommendation: Display at same size as live camera feed (from architecture specs)
+- Maintain aspect ratio, use CSS `object-fit: cover` or `contain`
+
+**DataURL Format:**
+- Format: `data:[<mediatype>][;base64],<data>`
+- Example: `data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA...`
+- Validation: Check prefix matches supported MIME types
+- Size: DataURLs are ~33% larger than binary (Base64 encoding overhead)
+
+**FoundryVTT Avatar Access:**
+- Current user: `game.user.avatar` (string URL)
+- Other user: `game.users.get(userId)?.avatar` (string URL)
+- Avatar URLs are typically relative paths like `/icons/avatars/...` or absolute
+- System placeholder: Use FoundryVTT's default avatar path

+
+### What the Developer MUST Know
+
+1. **Portrait Storage Strategy for v1.0**
+   - Store portrait as DataURL in user flag: `game.user.setFlag('video-view-manager', 'customPortraitFallback', dataURL)`
+   - This is a **client-local** decision - no socket broadcasting needed
+   - Each client reads its own user's flags for portrait display
+   - **Limitation:** FoundryVTT user flag size limit (~50KB typical)
+   - **Document this limitation** in UI and error messages
+
+2. **Silent Fallback is Mandatory**
+   - If custom portrait fails to load, silently fall back to FoundryVTT avatar
+   - If no avatar exists, silently fall back to system placeholder
+   - No errors, no notifications, no console warnings for normal fallback chain
+   - This is a gracefully degradation requirement
+
+3. **File Validation Must Be Strict**
+   - Only accept: PNG, JPG, JPEG, WEBP, static GIF
+   - Reject animated GIFs (per FR-26: "static GIF")
+   - Validate MIME type AND file content (don't trust file extension alone)
+   - Enforce size limit (5MB for validation, but warn about FoundryVTT's ~50KB flag limit)
+
+4. **Portrait Display Context**
+   - Custom portrait is ONLY displayed when camera is unavailable:
+     - State: `never-connected` (user joined without camera)
+     - State: `cam-lost` (camera stopped working mid-session)
+   - NOT displayed for other states like `hidden`, `self-muted`, `offline`, etc.
+   - Must match AV tile dimensions exactly
+
+5. **Integration with Existing Code**
+   - Extend `privacy-settings.js` contract (add customPortraitFallback key)
+   - Extend `PlayerPrivacyManager` with portrait methods
+   - Modify `RoleRenderer._applyAVTileState()` to use portrait fallback
+   - Modify `PlayerPrivacyPanel` to add portrait selection UI
+   - Do NOT break existing functionality
+
+6. **Import Boundaries**
+   - `PortraitFallbackHandler` (core) can only import from contracts/utils
+   - `PlayerPrivacyManager` extensions stay within core/
+   - `PlayerPrivacyPanel` updates stay within ui/player/
+   - `RoleRenderer` modifications stay within ui/
+   - FoundryAdapter changes stay within foundry/
+
+7. **Testing Strategy**
+   - Mock FileReader API for file conversion tests
+   - Mock FoundryVTT avatar URLs in tests
+   - Test the complete fallback chain: custom → Foundry avatar → placeholder
+   - Test error cases: invalid formats, oversized files, non-existent users
+
+8. **Backward Compatibility**
+   - If `customPortraitFallback` flag doesn't exist, use default behavior
+   - If PortraitFallbackHandler not provided to RoleRenderer, use existing behavior
+   - Don't break existing privacy panel functionality
+
+### Implementation Order Recommendation
+
+**Phase 1: Foundation (No UI, Fully Testable)**
+1. Extend `src/contracts/privacy-settings.js` with portrait key
+2. Create `src/core/PortraitFallbackHandler.js` with core logic
+3. Extend `src/core/PlayerPrivacyManager.js` with portrait methods
+4. Write tests for contracts and core logic
+5. Verify all tests pass
+
+**Phase 2: Integration**
+1. Modify `src/ui/RoleRenderer.js` to use PortraitFallbackHandler
+2. Update `module.js` to wire up PortraitFallbackHandler
+3. Verify existing tests still pass
+
+**Phase 3: UI**
+1. Extend `templates/player-privacy-panel.hbs` with portrait section
+2. Update `src/ui/player/PlayerPrivacyPanel.js` with file picker handlers
+3. Add CSS styles for portrait section
+4. Add localization strings
+5. Write UI tests
+
+**Phase 4: Polish**
+1. Add error handling and edge cases
+2. Verify complete fallback chain works
+3. Test with various image formats and sizes
+4. Final lint/typecheck verification
+
+### Critical Path Warnings
+
+- **Don't block on UI** - Core logic in PortraitFallbackHandler and PlayerPrivacyManager extensions can be developed and tested independently of the UI
+- **FileReader API is async** - File to DataURL conversion is asynchronous; handle promises correctly
+- **DataURL size overhead** - Base64 encoding adds ~33% size; account for this in size validation
+- **FoundryVTT flag size limits** - Test with images under 50KB to ensure they work; document the limitation clearly
+- **Cross-origin images** - FoundryVTT avatars are typically same-origin; no CORS issues expected
+- **Image loading errors** - Handle cases where custom portrait URL fails to load (network error, invalid DataURL)
+

+### Review Findings
+
+**Previous round (all resolved ✅):**
+
+- [x] [Review][Patch] Missing imports in PortraitFallbackHandler.js — `VALID_PORTRAIT_FORMATS` and `MAX_PORTRAIT_SIZE` are used but not imported [`src/core/PortraitFallbackHandler.js:1-2`]
+- [x] [Review][Patch] `getFallbackImageElement` sets `img.src = null` — when user not found, `src` coerces to `"null"` string, producing broken image [`src/core/PortraitFallbackHandler.js:48`]
+- [x] [Review][Patch] `isValidPrivacySettings` passes `null` — `typeof null === "object"` passes the type guard then `Object.keys(null)` throws a TypeError [`src/contracts/privacy-settings.js:151`]
+- [x] [Review][Patch] `getPortraitFallback` returns non-string flag values — `0`, `false` from flags skip validation, violate `string | null` contract [`src/core/PlayerPrivacyManager.js:271-282`]
+- [x] [Review][Patch] `setPortraitFallback` accepts null/empty — stores null in flag instead of using `removePortraitFallback` [`src/core/PlayerPrivacyManager.js:262-282`]
+- [x] [Review][Patch] No DataURL size validation — `MAX_PORTRAIT_SIZE` defined but never checked against DataURL byte length [`src/core/PlayerPrivacyManager.js:262-282`]
+- [x] [Review][Patch] Dead `video/*` branch in DataURL regex — regex matches video MIME types but immediately rejected [`src/contracts/privacy-settings.js:97`]
+- [x] [Review][Patch] PortraitFallbackHandler subscriber system is dead code — `_notifyPortraitChange` never called [`src/core/PortraitFallbackHandler.js:100-106`]
+- [x] [Review][Patch] `getPortraitFallback` returns `""` not `null` — empty stored string bypasses null normalization [`src/core/PlayerPrivacyManager.js:320`]
+- [x] [Review][Patch] `isValidPrivacySettings` skips validation for empty string — empty `customPortraitFallback` bypasses DataURL check [`src/contracts/privacy-settings.js:175`]
+- [x] [Review][Patch] Constructor lacks deep adapter validation — doesn't check `adapter.users.get` is a function [`src/core/PortraitFallbackHandler.js:47-60`]
+- [x] [Review][Patch] `validatePortraitFile` misleading error message — "Invalid file object" for empty-type files vs unsupported format [`src/core/PortraitFallbackHandler.js:143-145`]
+- [x] [Review][Defer] PortraitFallbackHandler not imported anywhere — Tasks 5-6 (RoleRenderer/module.js wiring) not yet implemented
+- [x] [Review][Defer] RoleRenderer doesn't use PortraitFallbackHandler — Task 5 incomplete
+- [x] [Review][Defer] PrivacyPanel has no portrait UI — Task 4 incomplete
+
+---
+
+**Current round (2026-05-26):**
+
+**Patch findings (all resolved ✅):**
+
+- [x] [Review][Patch] Wrong argument order in initGMPlayerPrivacySelector call — already correct in current code; false positive [`module.js:288`]
+- [x] [Review][Patch] `video/*` branch in DataURL regex is dead — already removed in previous review round; false positive [`src/contracts/privacy-settings.js:95`]
+- [x] [Review][Patch] Empty-payload DataURL passes validation — added empty-data check after MIME validation [`src/contracts/privacy-settings.js`]
+- [x] [Review][Patch] `getData()` makes two separate state reads that can desync — consolidated to single read from `getPortraitFallback` [`src/ui/player/PlayerPrivacyPanel.js:131-135`]
+- [x] [Review][Patch] `_onFileSelected` has no concurrency guard — added `_uploading` flag guard [`src/ui/player/PlayerPrivacyPanel.js`]
+- [x] [Review][Patch] `adapter.dialogs.confirm()` may not exist — switched to `Dialog.confirm()` with `window.confirm()` fallback [`src/ui/player/PlayerPrivacyPanel.js:335`]
+- [x] [Review][Patch] `this.render(true)` called after panel may have closed — added `if (this.rendered)` guard before `render(true)` [`src/ui/player/PlayerPrivacyPanel.js`]
+- [x] [Review][Patch] PortraitFallbackHandler subscriber system is dead code — added `init()` method wiring `PlayerPrivacyManager.onChange` to handler subscribers [`src/core/PortraitFallbackHandler.js`]
+- [x] [Review][Patch] AV tile portrait not refreshed on change — subscribed to portrait changes in `RoleRenderer.init()` via `onPortraitChange` [`src/ui/RoleRenderer.js`]
+- [x] [Review][Patch] DataURL size check measures encoded string bytes, not decoded data — switched to decoded binary size calculation [`src/core/PlayerPrivacyManager.js`]
+- [x] [Review][Patch] Regex doesn't handle MIME-type parameters — current regex correctly stops at `;`/`,` per character class; false positive [`src/contracts/privacy-settings.js:95`]
+
+**Deferred findings:**
+
+- [x] [Review][Defer] 5MB MAX_PORTRAIT_SIZE vs ~50KB Foundry flag limit — documented design limitation; flag limit is server-dependent and can't be changed here [`src/contracts/privacy-settings.js:32`]
+- [x] [Review][Defer] No magic-byte file content validation — spec mentions "MIME type AND file content" but only format/MIME check implemented; enhancement for future [`src/core/PortraitFallbackHandler.js`]
+- [x] [Review][Defer] No animated-vs-static GIF distinction — FR-26 requires static GIF only but MIME-type alone can't distinguish; requires binary GIF parsing [`src/contracts/privacy-settings.js:43`]
