+## Context
+
+Currently, the frontend displays raw UUIDs for user references:
+- Task list shows `assigneeId` (e.g., "a1b2c3d4-e5f6...") or "Unassigned"
+- Task detail shows `assigneeId` and `createdById` 
+- Shift detail shows `memberId` for each signup
+
+The backend already stores `DisplayName` in the `Member` entity but the API DTOs don't expose it. The `ShiftService` already demonstrates the pattern of joining with Members (lines 82-87), which we can replicate for Tasks.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Add member name fields to backend DTOs
+- Update TaskService to query and include member names
+- Update ShiftService to include member name in ShiftSignupDto
+- Update frontend TypeScript interfaces
+- Replace UUID displays with names in task/shift UIs
+
+**Non-Goals:**
+- No database schema changes
+- No changes to authentication or authorization
+- No changes to how tasks/shifts are created or updated
+- No caching layer for member names
+
+## Decisions
+
+### 1. Add names to existing DTOs vs create new DTOs
+**Decision:** Add optional fields to existing DTOs
+
+**Rationale:**
+- Keeps API surface simple
+- Backward compatible - existing clients ignore new fields
+- No breaking changes to existing integrations
+
+**Alternative considered:** Create new DTO versions (e.g., `TaskDetailDtoV2`)
+- Rejected: Unnecessary complexity for a simple additive change
+
+### 2. Fetch member names via JOIN vs separate query
+**Decision:** Use JOIN in TaskService methods
+
+**Rationale:**
+- More efficient - single query per endpoint
+- Pattern already exists in ShiftService
+- Avoids N+1 query problem
+
+**Alternative considered:** Query members separately and build lookup dictionary
+- Rejected: Adds complexity and extra database round-trips
+
+### 3. Handle missing members (orphaned IDs)
+**Decision:** Return null for name when member not found
+
+**Rationale:**
+- Data integrity issue should surface visibly
+- Frontend can display fallback like "Unknown" or keep showing ID
+- Logging can track data inconsistencies
+
+### 4. Frontend handling of null names
+**Decision:** Frontend shows fallback text when name is null
+
+**Implementation:**
+```typescript
+// Task list
+task.assigneeName || 'Unassigned'
+
+// Task detail
+task.assigneeName || 'Unassigned'
+task.createdByName || 'Unknown'
+
+// Shift signups
+signup.memberName || 'Unknown Member'
+```
+
+## Risks / Trade-offs
+
+| Risk | Mitigation |
+|------|-----------|
+| JOIN adds query complexity | Keep JOINs simple, only on indexed columns (Member.Id) |
+| Larger API response payloads | Minimal impact - names are small strings |
+| Member names become stale | Acceptable - names rarely change; eventual consistency |
+| Database performance degradation | Monitor query execution plans; add caching if needed |
+| Partial data on member deletion | Show "Unknown" fallback; log orphaned references |
+
+## Migration Plan
+
+1. **Backend DTO changes** - Add new optional fields
+2. **Backend service changes** - Update queries to include names
+3. **Frontend type updates** - Add name fields to interfaces
+4. **Frontend UI updates** - Replace ID displays with names
+
+**Rollback:**
+- DTO changes are backward compatible
+- Frontend can revert to showing IDs by changing display logic
+- No database changes required
+
+## Open Questions
+
+- Should we include `externalUserId` in the signup display? (Currently available in ShiftSignupDto)
+- Do we need to include member email for any display purposes?
+- Should we add name fields to shift list items (showing creator name)?

+## Why
+
+Currently, the frontend displays raw UUIDs for user references (assignee, creator, members) which creates a poor user experience. Users should see meaningful names like "Alice Smith" instead of "a1b2c3d4-e5f6-7890-abcd-ef1234567890". The backend already stores display names in the Member entity, but the API DTOs don't expose them.
+
+## What Changes
+
+- **Backend DTOs**: Add name fields to task and shift DTOs
+  - `TaskListItemDto`: Add `string? AssigneeName`
+  - `TaskDetailDto`: Add `string? AssigneeName` and `string CreatedByName`
+  - `ShiftSignupDto`: Add `string MemberName`
+- **Backend Services**: Update TaskService and ShiftService to query and populate member names
+  - Join with Members table to fetch display names
+  - Include names in DTO construction
+- **Frontend Types**: Update TypeScript interfaces to include new name fields
+  - `TaskListItemDto`, `TaskDetailDto`, `ShiftSignupDto` interfaces
+- **Frontend UI**: Replace UUID displays with names
+  - Task list: show assignee name instead of ID
+  - Task detail: show assignee and creator names
+  - Shift detail: show member names in signup list
+
+## Capabilities
+
+### New Capabilities
+- `member-name-enrichment`: API DTOs include human-readable member names alongside IDs
+
+### Modified Capabilities
+- None (this is purely an enhancement to existing capabilities)
+
+## Impact
+
+- **Backend**: TaskService.cs, ShiftService.cs, and DTOs in WorkClub.Application
+- **Frontend**: Tasks pages, Shifts pages, and React hooks (useTasks.ts, useShifts.ts)
+- **Database**: Additional JOIN queries on Members table (no schema changes)
+- **API Response**: New optional fields in existing endpoints (backward compatible)

+## ADDED Requirements
+
+### Requirement: Task list items include assignee name
+The API SHALL return the assignee's display name in TaskListItemDto.
+
+#### Scenario: Task with assignee
+- **WHEN** a task is assigned to a member
+- **THEN** the TaskListItemDto SHALL include the assignee's DisplayName as `assigneeName`
+
+#### Scenario: Task without assignee
+- **WHEN** a task has no assignee
+- **THEN** the TaskListItemDto SHALL have `assigneeName` set to null
+
+### Requirement: Task details include creator and assignee names
+The API SHALL return the display names of both the creator and assignee in TaskDetailDto.
+
+#### Scenario: Viewing task details
+- **WHEN** a user requests task details
+- **THEN** the TaskDetailDto SHALL include `createdByName` (the creator's DisplayName)
+- **AND** the TaskDetailDto SHALL include `assigneeName` (the assignee's DisplayName, or null if unassigned)
+
+### Requirement: Shift signup includes member name
+The API SHALL return the member's display name in ShiftSignupDto.
+
+#### Scenario: Viewing shift signups
+- **WHEN** a user views shift details with signups
+- **THEN** each ShiftSignupDto SHALL include `memberName` (the member's DisplayName)
+
+### Requirement: Frontend displays names instead of UUIDs
+The frontend SHALL render member names instead of UUIDs wherever user references appear.
+
+#### Scenario: Task list view
+- **WHEN** viewing the task list
+- **THEN** the Assignee column SHALL display the assignee's name (or "Unassigned")
+
+#### Scenario: Task detail view
+- **WHEN** viewing a task detail page
+- **THEN** the Assignee field SHALL display the assignee's name (or "Unassigned")
+- **AND** the Created By field SHALL display the creator's name
+
+#### Scenario: Shift detail view
+- **WHEN** viewing a shift detail page with signups
+- **THEN** the member list SHALL display each member's name instead of their ID
