+## Technical Design: API Resource Standard
+
+### Overview
+This design establishes Laravel API Resources as the standard for all API responses, ensuring consistent `"data"` wrapper across all endpoints.
+
+---
+
+### Directory Structure

+```
+
+---
+
+### Base Resource Design
+
+```php
+<?php
+
+namespace App\Http\Resources;
+
+use Illuminate\Http\Resources\Json\JsonResource;
+
+abstract class BaseResource extends JsonResource
+{
+    /**
+     * Standard date format for all API responses
+     */
+    protected function formatDate($date): ?string
+    {
+        return $date?->toIso8601String();
+    }
+
+    /**
+     * Format decimal values consistently
+     */
+    protected function formatDecimal($value, int $decimals = 2): ?float
+    {
+        return $value !== null ? round((float) $value, $decimals) : null;
+    }
+}
+```
+
+---
+
+### Resource Implementation Pattern
+
+Each resource follows this pattern:
+
+```php
+<?php
+
+namespace App\Http\Resources;
+
+class TeamMemberResource extends BaseResource
+{
+    public function toArray($request): array
+    {
+        return [
+            'id' => $this->id,
+            'name' => $this->name,
+            'role' => new RoleResource($this->whenLoaded('role')),
+            'hourly_rate' => $this->formatDecimal($this->hourly_rate),
+            'active' => (bool) $this->active,
+            'created_at' => $this->formatDate($this->created_at),
+            'updated_at' => $this->formatDate($this->updated_at),
+        ];
+    }
+}
+```
+
+---
+
+### Controller Update Pattern
+
+**BEFORE:**
+```php
+public function index(Request $request): JsonResponse
+{
+    $members = $this->teamMemberService->getAll();
+    return response()->json($members);
+}
+```
+
+**AFTER:**
+```php
+public function index(Request $request): JsonResponse
+{
+    $members = $this->teamMemberService->getAll();
+    return response()->json(new TeamMemberResource($members));
+    // Or for collections:
+    // return response()->json(TeamMemberResource::collection($members));
+}
+```
+
+---
+
+### Relationship Loading Strategy
+
+Use Laravel's `whenLoaded()` to conditionally include relationships:
+
+```php
+public function toArray($request): array
+{
+    return [
+        'id' => $this->id,
+        'name' => $this->name,
+        // Only include role if it was eager loaded
+        'role' => new RoleResource($this->whenLoaded('role')),
+        // Only include team_member if it was eager loaded  
+        'team_member' => new TeamMemberResource($this->whenLoaded('teamMember')),
+    ];
+}
+```
+
+**Controller Responsibility:**
+```php
+// Eager load relationships before passing to resource
+$members = TeamMember::with('role')->get();
+return response()->json(TeamMemberResource::collection($members));
+```
+
+---
+
+### Frontend API Client Update
+
+**Create helper function to unwrap responses:**
+
+```typescript
+// src/lib/api/client.ts
+
+export async function unwrapResponse<T>(response: Response): Promise<T> {
+  const data = await response.json();
+  return data.data as T;
+}
+
+// Usage in API functions:
+export async function getTeamMembers(): Promise<TeamMember[]> {
+  const response = await fetch('/api/team-members');
+  return unwrapResponse<TeamMember[]>(response);
+}
+```
+
+**Update all API calls:**
+```typescript
+// BEFORE:
+const members = await response.json();
+
+// AFTER:
+const members = await unwrapResponse<TeamMember[]>(response);
+```
+
+---
+
+### Test Update Pattern
+
+**Backend Feature Tests:**
+```php
+// BEFORE:
+$response->assertJson(['name' => 'John Doe']);
+
+// AFTER:
+$response->assertJson(['data' => ['name' => 'John Doe']]);
+// Or more explicitly:
+$this->assertEquals('John Doe', $response->json('data.name'));
+```
+
+**Resource Unit Tests:**
+```php
+test('resource wraps single model in data key', function () {
+    $member = TeamMember::factory()->create();
+    $resource = new TeamMemberResource($member);
+    
+    $this->assertArrayHasKey('data', $resource->resolve());
+    $this->assertEquals($member->id, $resource->resolve()['data']['id']);
+});
+
+test('collection wraps in data array', function () {
+    $members = TeamMember::factory(3)->create();
+    $collection = TeamMemberResource::collection($members);
+    
+    $this->assertArrayHasKey('data', $collection->resolve());
+    $this->assertCount(3, $collection->resolve()['data']);
+});
+```
+
+---
+
+### Caching Considerations
+
+API Resources don't affect caching strategy - they transform data at response time. Cache storage remains the same:
+
+```php
+// Cache raw model data (not transformed resources)
+$cached = Cache::remember('team-members:all', 3600, function () {
+    return TeamMember::with('role')->get();
+});
+
+// Transform on response
+return response()->json(TeamMemberResource::collection($cached));
+```
+
+---
+
+### Error Response Handling
+
+Error responses remain unchanged (no `"data"` wrapper):
+
+```php
+// Validation errors
+return response()->json([
+    'message' => 'The given data was invalid.',
+    'errors' => $validator->errors(),
+], 422);
+
+// Not found
+return response()->json([
+    'message' => 'Resource not found',
+], 404);
+```
+
+---
+
+### Scribe Documentation Updates
+
+Update all `@response` annotations to show new format:
+
+```php
+/**
+ * @response {
+ *   "data": {
+ *     "id": "550e8400-e29b-41d4-a716-446655440000",
+ *     "name": "John Doe"
+ *   }
+ * }
+ */
+```
+
+---
+
+### Migration Steps
+
+1. **Phase 1: Resources** - Create all resource classes
+2. **Phase 2: Controllers** - Update one controller at a time, run tests
+3. **Phase 3: Frontend** - Update API client helper, then each endpoint
+4. **Phase 4: Tests** - Update all test assertions
+5. **Phase 5: Docs** - Regenerate Scribe documentation
+
+---
+
+### Rollback Plan
+
+Since this is a breaking change for frontend:
+- Commit after each controller update
+- Run full test suite before next controller
+- If critical issue found, revert specific controller commit

+## Why
+
+The Headroom API currently returns raw JSON responses without a standardized wrapper. This violates the architecture specification (docs/headroom-architecture.md, lines 315-393) which mandates Laravel API Resources for consistent JSON structure. This technical debt creates several problems:
+
+1. **Inconsistent Response Format**: Some endpoints return arrays, others objects, making client-side parsing error-prone
+2. **No Future-Proofing**: Adding metadata (pagination, relationships, meta) requires breaking changes later
+3. **Missing Data Wrapper**: Architecture requires `"data"` key for all responses to support future transformations
+4. **No Resource Abstraction**: Direct model exposure limits ability to transform data without breaking clients
+
+Since the application is pre-production and not in active use, we should fix this now to avoid permanent technical debt.
+
+## What Changes
+
+### Breaking Changes
+- **BREAKING**: All API responses will be wrapped in `"data"` key
+- **BREAKING**: Collections will use Laravel's resource collection format with `"data"` array
+- **BREAKING**: Frontend API client must unwrap `response.data` instead of direct access
+
+### New Components
+- Create `app/Http/Resources/` directory structure
+- Create 11 API Resource classes for consistent transformation
+- Create base `BaseResource` with common formatting utilities
+
+### Updated Components
+- Update 6 controllers to use API Resources instead of `response()->json()`
+- Update 63 backend tests to expect `"data"` wrapper in responses
+- Update frontend API client to handle new response format
+- Regenerate Scribe API documentation
+
+## Capabilities
+
+### New Capabilities
+- `api-resource-standard`: Standardize all API responses using Laravel API Resources with consistent `"data"` wrapper
+
+### Modified Capabilities
+- *(none - this is a refactoring change, no functional requirements change)*
+
+## Impact
+
+### Backend (Laravel)
+- **Files Created**: 11 new resource classes in `app/Http/Resources/`
+- **Files Modified**: 6 controllers in `app/Http/Controllers/Api/`
+- **Tests Updated**: 63 feature tests
+- **New Tests**: 11+ unit tests for resource classes
+
+### Frontend (SvelteKit)
+- **Files Modified**: API client in `src/lib/api/` directory
+- **Breaking**: All API calls must access `response.json().data` instead of `response.json()`
+
+### Documentation
+- **Regenerated**: Scribe API docs will show new response format
+
+### Dependencies
+- No new dependencies required (Laravel's built-in API Resources)
+
+### Performance
+- Minimal impact - API Resources add negligible overhead
+- Slight improvement: Consistent caching keys can be optimized

+## ADDED Requirements
+
+### Requirement: API Response Standardization
+All API responses MUST follow Laravel API Resource format with consistent `"data"` wrapper.
+
+#### Scenario: Single resource response
+- **WHEN** an API endpoint returns a single model
+- **THEN** the response MUST have a `"data"` key containing the resource
+- **AND** the resource MUST include all required fields defined in the resource class
+
+**Example:**
+```json
+{
+  "data": {
+    "id": "550e8400-e29b-41d4-a716-446655440000",
+    "name": "John Doe",
+    "role": {
+      "id": 1,
+      "name": "Backend Developer"
+    },
+    "hourly_rate": 150.00,
+    "active": true,
+    "created_at": "2026-02-01T10:00:00Z"
+  }
+}
+```
+
+#### Scenario: Collection response
+- **WHEN** an API endpoint returns multiple models
+- **THEN** the response MUST have a `"data"` key containing an array
+- **AND** each item in the array MUST follow the single resource format
+
+**Example:**
+```json
+{
+  "data": [
+    {
+      "id": "550e8400-e29b-41d4-a716-446655440000",
+      "name": "John Doe",
+      "role": { "id": 1, "name": "Backend Developer" },
+      "hourly_rate": 150.00,
+      "active": true,
+      "created_at": "2026-02-01T10:00:00Z"
+    },
+    {
+      "id": "660e8400-e29b-41d4-a716-446655440001",
+      "name": "Jane Smith",
+      "role": { "id": 2, "name": "Frontend Developer" },
+      "hourly_rate": 140.00,
+      "active": true,
+      "created_at": "2026-02-01T10:00:00Z"
+    }
+  ]
+}
+```
+
+#### Scenario: Nested relationships
+- **WHEN** a resource has relationships (e.g., TeamMember has Role)
+- **THEN** the relationship MUST be nested within the resource
+- **AND** the nested resource SHOULD also follow the standard format
+
+#### Scenario: Error responses
+- **WHEN** an error occurs (validation, not found, etc.)
+- **THEN** the response format remains unchanged (no `"data"` wrapper for errors)
+- **AND** errors continue to use standard Laravel error format:
+```json
+{
+  "message": "The given data was invalid.",
+  "errors": {
+    "field": ["Error message"]
+  }
+}
+```
+

+
+## ADDED API Endpoints (Updated Format)
+
+All existing endpoints remain functionally identical, only response format changes:
+
+### Auth Endpoints
+| Endpoint | Method | Response Type |
+|----------|--------|---------------|
+| POST /api/auth/login | Auth | UserResource with tokens |
+| POST /api/auth/refresh | Auth | UserResource with new token |

+| POST /api/team-members | Single | TeamMemberResource |
+| GET /api/team-members/{id} | Single | TeamMemberResource |
+| PUT /api/team-members/{id} | Single | TeamMemberResource |
+| DELETE /api/team-members/{id} | Message | { message: "..." } |
+

+
+---
+
+## ADDED Test Requirements
+
+### Resource Unit Tests
+Each resource MUST have unit tests verifying:
+1. Single resource returns `"data"` wrapper
+2. Collection returns `"data"` array wrapper
+3. All expected fields are present
+4. Sensitive fields are excluded (e.g., password)
+5. Relationships are properly nested
+6. Date formatting follows ISO 8601
+
+### Feature Test Updates
+All 63 existing feature tests MUST be updated to:
+1. Assert response has `"data"` key
+2. Access nested data via `response.json()['data']`
+3. Verify collection responses have `"data"` array
+
+### E2E Test Verification
+All 134 E2E tests MUST pass after frontend API client is updated.
+
+---
+
+## REMOVED
+
+- Direct `response()->json($model)` calls in controllers
+- Raw array/object responses without `"data"` wrapper

+# Decision Log: capacity-expert-mode
+
+## 2026-02-24 — Timezone & Accessibility Fixes
+
+### Issue
+User reported that weekend shading in Expert Mode was misaligned (showing on 5th/6th instead of 4th/5th for April 2026). Additionally, the shading was too subtle for colorblind users, and cells were not prefilled with `O`/`H` for weekends/holidays.
+
+### Root Cause
+Browser `new Date('YYYY-MM-DD')` interprets dates in local timezone, causing dates to shift for users west of UTC. A user in UTC-6 sees `2026-04-04` as `2026-04-03T18:00`, which reports as Friday instead of Saturday.
+
+### Decisions Made
+
+| # | Decision | Rationale |
+|---|----------|-----------|
+| D8 | Use Eastern Time (America/New_York) as canonical timezone for weekend/holiday detection | Ensures consistent business-day alignment; future configurable |
+| D9 | Use high-contrast styling for weekends/holidays (solid backgrounds + borders) | Accessibility for colorblind users |
+| D10 | Prefill weekends with `O`, holidays with `H` on grid load | Matches user expectations; reduces manual entry |
+| D11 | Frontend and backend must sync when seeding default values | Prevents divergent behavior on refresh |
+
+### Implementation Notes
+- Frontend: Parse dates as `new Date(dateStr + 'T00:00:00')` to avoid timezone drift
+- Backend: Use Carbon with `America/New_York` timezone
+- Both sides must implement identical prefill logic
+
+### Future Considerations
+- Make timezone configurable per-team or per-user (v2)
+- Extract prefill rules to shared configuration
+

+## Context
+
+Capacity Planning currently uses a per-member calendar card view: one team member selected at a time, one dropdown per day. This is readable but slow — unsuitable for a daily standup where a manager needs to review and adjust the whole team's availability in under a minute.
+
+The sample spreadsheet (`test-results/Sample-Capacity-Expert.xlsx`) demonstrates the target UX: a dense matrix with members as rows and days as columns, using short tokens (`H`, `O`, `0`, `.5`, `1`) for fast keyboard entry, with live KPI totals at the top.
+
+Expert Mode is additive — the existing calendar, summary, holidays, and PTO tabs remain unchanged.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Spreadsheet-style planning grid: all team members × all working days in one view
+- Token-based cell input: `H`, `O`, `0`, `.5`, `0.5`, `1` only
+- Live KPI bar: Capacity (person-days) and Projected Revenue update as cells change
+- Batch save: single Submit commits all pending changes in one API call
+- Toggle persisted in `localStorage` so standup users stay in Expert Mode
+- Auto-render `0` as `O` on weekend columns, `H` on holiday columns
+- Invalid token → red cell on blur, Submit globally disabled
+
+**Non-Goals:**
+- Arbitrary decimal availability values (e.g. `0.25`, `0.75`) — v1 stays at `0/0.5/1`
+- Scenario planning / draft versioning
+- Multi-month grid view
+- Import/export to Excel/CSV (deferred to Phase 2)
+- Real-time multi-user collaboration / conflict resolution
+- Role-based access control for Expert Mode (all authenticated users can use it)
+
+## Decisions
+
+### D1: Token model — display vs. storage
+
+**Decision**: Separate `rawToken` (display) from `numericValue` (math/storage).
+
+```
+cell = {
+  rawToken:     "H" | "O" | "0" | ".5" | "0.5" | "1" | <invalid string>,
+  numericValue: 0 | 0.5 | 1 | null,   // null = invalid
+  dirty:        boolean,               // changed since last save
+  valid:        boolean
+}
+```
+
+Normalization table:
+| Input | numericValue | Display |
+|-------|-------------|---------|
+| `H`   | `0`         | `H`     |
+| `O`   | `0`         | `O`     |
+| `0`   | `0`         | `0` (or `O`/`H` if weekend/holiday — see D3) |
+| `.5`  | `0.5`       | `0.5`   |
+| `0.5` | `0.5`       | `0.5`   |
+| `1`   | `1`         | `1`     |
+| other | `null`      | raw text (red) |
+
+**Rationale**: Keeps math clean, preserves user intent in display, avoids ambiguity in totals.
+
+**Alternative considered**: Store `H`/`O` as strings in DB — rejected because it would require schema changes and break existing capacity math.
+
+---
+
+### D2: Batch API endpoint
+
+**Decision**: Add `POST /api/capacity/availability/batch` accepting an array of availability updates.
+
+```json
+// Request
+{
+  "month": "2026-02",
+  "updates": [
+    { "team_member_id": "uuid", "date": "2026-02-03", "availability": 1 },
+    { "team_member_id": "uuid", "date": "2026-02-04", "availability": 0.5 }
+  ]
+}
+
+// Response 200
+{
+  "data": {
+    "saved": 12,
+    "month": "2026-02"
+  }
+}
+```
+
+Validation: each `availability` must be in `[0, 0.5, 1]`. Month-level cache flushed once after all upserts (not per-row).
+
+**Rationale**: Single-cell endpoint (`POST /api/capacity/availability`) would require N calls for N dirty cells — too chatty for standup speed. Batch endpoint reduces to 1 call and 1 cache flush.
+
+**Alternative considered**: WebSocket streaming — overkill for v1, deferred.
+
+---
+
+### D3: Auto-render `0` as contextual marker
+
+**Decision**: On blur, if `numericValue === 0` and the column is a weekend → display `O`; if column is a holiday → display `H`; otherwise display `0`.
+
+**Rationale**: Keeps the grid visually scannable (weekends/holidays obvious at a glance) without forcing users to type `O`/`H` manually.
+
+**Alternative considered**: Always show `0` — simpler but loses the visual shorthand that makes standups fast.
+
+---
+
+### D4: localStorage persistence for toggle
+
+**Decision**: Persist Expert Mode preference as `headroom.capacity.expertMode` (boolean) in `localStorage`. Default `false`.
+
+**Rationale**: No backend dependency, instant, consistent with existing sidebar/layout persistence pattern in the app. Multi-device sync is not a requirement for v1.
+
+---
+
+### D5: Toggle placement
+
+**Decision**: Expert Mode toggle (label + switch) sits right-aligned on the same row as the Calendar/Summary/Holidays/PTO tabs.
+
+```
+[Calendar] [Summary] [Holidays] [PTO]          Expert mode [OFF●ON]
+```
+
+**Rationale**: Tabs are content sections; Expert Mode is a view behavior. Placing it as a tab would imply it's a separate section rather than a mode overlay. Right-aligned toggle is a common pattern (e.g. "Compact view", "Dark mode") that communicates "this changes how you see things, not what you see."
+
+---
+
+### D6: Submit gating
+
+**Decision**: The Submit button is disabled if:
+1. Any cell has `valid === false`, OR
+2. No cells are `dirty` (nothing to save)
+
+On submit: collect all dirty+valid cells, POST to batch endpoint, clear dirty flags on success, show toast.
+
+**Rationale**: Prevents partial saves with invalid data. Dirty check avoids unnecessary API calls.
+
+---
+
+### D7: Grid data loading
+
+**Decision**: Expert Mode loads all team members' individual capacity in parallel on mount (one request per member). Results are merged into a single grid state object keyed by `{memberId, date}`.
+
+**Rationale**: Existing `GET /api/capacity?month=&team_member_id=` endpoint already returns per-member details. Reusing it avoids a new read endpoint. Parallel fetching keeps load time acceptable for typical team sizes (8–20 members).
+
+**Alternative considered**: New `GET /api/capacity/team/details` returning all members in one call — valid future optimization, deferred.
+
+---
+
+### D8: Timezone normalization for weekend/holiday detection
+
+**Decision**: All date calculations for weekend/holiday detection MUST use Eastern Time (America/New_York) as the canonical timezone. Both frontend and backend must use the same timezone normalization to ensure consistent cell styling and prefill behavior.
+
+**Implementation**:
+- Frontend: Use `new Date(dateStr + 'T00:00:00')` or parse date components manually to avoid local timezone drift
+- Backend: Use Carbon with `timezone('America/New_York')` for all weekend/holiday checks
+- Future: Make timezone configurable per-team or per-user (deferred to v2)
+
+**Rationale**: Browser `new Date('YYYY-MM-DD')` interprets the date in local timezone, causing weekend columns to shift by one day for users in timezones behind UTC (e.g., a Saturday showing as Friday in Pacific Time). Eastern Time provides consistent business-day alignment for US-based teams.
+
+**Example bug fixed**: April 2026 — 4th and 5th are Saturday/Sunday. Without timezone normalization, users in UTC-6 or later saw weekend shading on 5th and 6th instead.
+
+---
+
+### D9: Accessibility-enhanced weekend/holiday styling
+
+**Decision**: Weekend and holiday cells must use high-contrast visual treatments that work for colorblind users:
+
+| Cell Type | Background | Border | Additional Indicator |
+|-----------|------------|--------|---------------------|
+| Weekend   | `bg-base-300` (solid) | `border-base-400` | — |
+| Holiday   | `bg-warning/40` | `border-warning` | Bold `H` marker in cell |
+
+**Rationale**: Previous implementation used subtle opacity (`bg-base-200/30`, `bg-warning/10`) which was nearly invisible for colorblind users. Solid backgrounds with borders provide sufficient contrast without relying solely on color differentiation.
+
+---
+
+### D10: Prefill weekends with `O`, holidays with `H`
+
+**Decision**: When loading a month in Expert Mode, cells for weekend days must be prefilled with `O` (Off) and cells for holidays must be prefilled with `H`. This applies to:
+1. Initial grid load (no existing availability data)
+2. Days that would otherwise default to `1` (full availability)
+
+**Frontend behavior**:
+```typescript
+function getDefaultValue(date: string, isWeekend: boolean, isHoliday: boolean): NormalizedToken {
+  if (isHoliday) return { rawToken: 'H', numericValue: 0, valid: true };
+  if (isWeekend) return { rawToken: 'O', numericValue: 0, valid: true };
+  return { rawToken: '1', numericValue: 1, valid: true };
+}
+```
+
+**Backend behavior**: When seeding availability for a new month, the backend must also use this logic to ensure consistency. Frontend and backend MUST stay in sync.
+
+**Rationale**: Users expect weekends and holidays to be "off" by default. Prefilling communicates this immediately and reduces manual entry. Synchronizing frontend/backend prevents confusion where one shows defaults the other doesn't recognize.
+
+---
+
+### D11: Frontend/Backend sync when seeding months
+
+**Decision**: Any logic that determines default availability values (weekend = O, holiday = H, weekday = 1) must be implemented identically in both frontend and backend. Changes to this logic require updating both sides simultaneously.
+
+**Enforcement**:
+- Shared documentation of the prefill rules (this design.md)
+- Unit tests on both sides that verify the same inputs produce the same outputs
+- Consider extracting to a shared configuration file or API endpoint in v2
+
+**Rationale**: Divergent defaults cause confusing UX where the grid shows one thing but the backend stores another, or where refresh changes values unexpectedly.
+
+---
+
+## Risks / Trade-offs
+
+| Risk | Mitigation |
+|------|-----------|
+| Large teams (50+ members) make grid slow to load | Parallel fetch + loading skeleton; virtual scrolling deferred to v2 |
+| Cache invalidation storm on batch save | `CapacityService::batchUpsertAvailability()` flushes month-level cache once after all upserts, not per-row |
+| User switches mode with unsaved dirty cells | Warn dialog: "You have unsaved changes. Discard?" before switching away |
+| Two users editing same month simultaneously | Last-write-wins (acceptable for v1; no concurrent editing requirement) |
+| Wide grid overflows on small screens | Horizontal scroll on grid container; toggle hidden on mobile (< md breakpoint) |
+| `.5` normalization confusion | Normalize on blur, not on keystroke — user sees `.5` become `0.5` only after leaving cell |
+
+## Migration Plan
+
+- No database migrations required.
+- No breaking API changes — new batch endpoint is additive.
+- Feature flag: Expert Mode toggle defaults to `false`; users opt in.
+- Rollback: remove toggle + grid component; existing calendar mode unaffected.
+
+## Open Questions
+
+- *(Resolved)* Token set: `H`, `O`, `0`, `.5`, `0.5`, `1` only.
+- *(Resolved)* `H` and `O` are interchangeable (both = `0`).
+- *(Resolved)* `0` on weekend auto-renders `O`; on holiday auto-renders `H`.
+- *(Resolved)* Persist toggle in `localStorage`.
+- Should Expert Mode be accessible to all roles, or only Superuser/Manager? → **v1: all authenticated users** (RBAC deferred).
+- Should the KPI bar show per-member revenue breakdown inline, or only team totals? → **v1: team totals only** (matches sample sheet header).

+## Why
+
+Capacity planning today requires switching between team members one at a time in a calendar card view — too slow for a daily standup. Managers need a spreadsheet-style grid where the entire team's availability for the month is visible and editable at a glance, in under a minute.
+
+## What Changes
+
+- Add an **Expert Mode toggle** to the Capacity Planning page (right-aligned on the tabs row), persisted in `localStorage`.
+- When Expert Mode is ON, replace the per-member calendar card view with a **dense planning grid**: team members as rows, days-of-month as columns.
+- Each cell accepts exactly one of: `H`, `O`, `0`, `.5`, `0.5`, `1` — any other value is invalid (red on blur, submit disabled globally).
+- `H` and `O` are interchangeable display tokens that both normalize to `0` for math; the frontend always preserves and displays the typed token.
+- Typing `0` on a weekend column auto-renders as `O`; typing `0` on a holiday column auto-renders as `H`.
+- Live KPI bar above the grid shows **Capacity (person-days)** and **Projected Revenue** updating as cells change.
+- Batch save: a single **Submit** button commits all pending changes; disabled while any invalid cell exists.
+- Backend gains a new **batch availability endpoint** to accept multiple `{team_member_id, date, availability}` entries in one request.
+
+## Capabilities
+
+### New Capabilities
+
+- `capacity-expert-mode`: Spreadsheet-style planning grid for bulk team availability editing with token-based input, live KPI bar, and batch save.
+
+### Modified Capabilities
+
+- `capacity-planning`: Existing per-member calendar and summary remain unchanged; Expert Mode is purely additive. No requirement changes to existing scenarios.
+
+## Impact
+
+- **Frontend**: New `CapacityExpertGrid` component; `capacity/+page.svelte` gains mode toggle + localStorage persistence; `capacity.ts` API client gains batch update function; new `expertModeStore` or localStorage util.
+- **Backend**: New `POST /api/capacity/availability/batch` endpoint in `CapacityController`; `CapacityService` gains `batchUpsertAvailability()` with consolidated cache invalidation.
+- **No schema changes**: `team_member_daily_availabilities` table is unchanged; values stored remain `0`, `0.5`, `1`.
+- **No breaking changes**: Existing calendar mode, summary, holidays, and PTO tabs are unaffected.
+- **Tests**: New unit tests for token normalization/validation; new feature test for batch endpoint; new component tests for grid and toggle.

+## ADDED Requirements
+
+### Requirement: Toggle Expert Mode
+The system SHALL provide a toggle switch on the Capacity Planning page that enables or disables Expert Mode. The toggle SHALL be persisted in `localStorage` under the key `headroom.capacity.expertMode` so the user's preference survives page reloads.
+
+#### Scenario: Toggle defaults to off
+- **WHEN** a user visits the Capacity Planning page for the first time
+- **THEN** Expert Mode is off and the standard calendar view is shown
+
+#### Scenario: Toggle persists across reloads
+- **WHEN** a user enables Expert Mode and reloads the page
+- **THEN** Expert Mode is still enabled and the grid view is shown
+
+#### Scenario: Toggle is right-aligned on the tabs row
+- **WHEN** the Capacity Planning page is rendered
+- **THEN** the Expert Mode toggle appears right-aligned on the same row as the Calendar, Summary, Holidays, and PTO tabs
+
+#### Scenario: Switching mode with unsaved changes warns user
+- **WHEN** a user has dirty (unsaved) cells in the Expert Mode grid
+- **AND** the user toggles Expert Mode off
+- **THEN** the system shows a confirmation dialog: "You have unsaved changes. Discard and switch?"
+- **AND** if confirmed, changes are discarded and the calendar view is shown
+
+---
+
+### Requirement: Display Expert Mode planning grid
+The system SHALL render a dense planning grid when Expert Mode is enabled. The grid SHALL show all active team members as rows and all days of the selected month as columns.
+
+#### Scenario: Grid shows all active team members
+- **WHEN** Expert Mode is enabled for a given month
+- **THEN** each active team member appears as a row in the grid
+- **AND** inactive team members are excluded
+
+#### Scenario: Grid shows all days of the month as columns
+- **WHEN** Expert Mode is enabled for February 2026
+- **THEN** the grid has 28 columns (one per calendar day)
+- **AND** each column header shows the day number
+
+#### Scenario: Weekend columns are visually distinct
+- **WHEN** the grid is rendered
+- **THEN** weekend columns (Saturday, Sunday) are visually distinguished (e.g. muted background)
+
+#### Scenario: Holiday columns are visually distinct
+- **WHEN** a day in the month is a company holiday
+- **THEN** that column header is visually marked as a holiday
+
+#### Scenario: Grid loads existing availability data
+- **WHEN** Expert Mode grid is opened for a month where availability overrides exist
+- **THEN** each cell pre-populates with the stored token matching the saved availability value
+
+---
+
+### Requirement: Cell token input and validation
+The system SHALL accept exactly the following tokens in each grid cell: `H`, `O`, `0`, `.5`, `0.5`, `1`. Any other value SHALL be treated as invalid.
+
+#### Scenario: Valid token accepted on blur
+- **WHEN** a user types `1` into a cell and moves focus away
+- **THEN** the cell displays `1` and is marked valid
+
+#### Scenario: Valid token `.5` normalized on blur
+- **WHEN** a user types `.5` into a cell and moves focus away
+- **THEN** the cell displays `0.5` and is marked valid with numeric value `0.5`
+
+#### Scenario: `H` and `O` accepted on any date
+- **WHEN** a user types `H` or `O` into any cell (weekend, holiday, or working day)
+- **THEN** the cell is marked valid with numeric value `0`
+- **AND** the display shows the typed token (`H` or `O`)
+
+#### Scenario: Invalid token marked red on blur
+- **WHEN** a user types `2` or `abc` or any value not in the allowed set into a cell and moves focus away

+- **AND** the raw text is preserved so the user can correct it
+
+#### Scenario: Submit disabled while invalid cell exists
+- **WHEN** any cell in the grid has an invalid token
+- **THEN** the Submit button is disabled
+
+#### Scenario: `0` auto-renders as `O` on weekend column
+- **WHEN** a user types `0` into a cell whose column is a weekend day and moves focus away
+- **THEN** the cell displays `O` (not `0`)
+- **AND** the numeric value is `0`
+
+#### Scenario: `0` auto-renders as `H` on holiday column
+- **WHEN** a user types `0` into a cell whose column is a company holiday and moves focus away
+- **THEN** the cell displays `H` (not `0`)
+- **AND** the numeric value is `0`
+
+---
+
+### Requirement: Live KPI bar in Expert Mode
+The system SHALL display a live KPI bar above the grid showing team-level Capacity (person-days) and Projected Revenue, updating in real time as cell values change.
+
+#### Scenario: KPI bar shows correct capacity on load
+- **WHEN** Expert Mode grid loads for a month
+- **THEN** the KPI bar shows total team capacity in person-days matching the sum of all members' numeric cell values
+
+#### Scenario: KPI bar updates when a cell changes
+- **WHEN** a user changes a valid cell from `1` to `0.5`
+- **THEN** the KPI bar immediately reflects the reduced capacity and revenue without a page reload
+
+#### Scenario: Invalid cells excluded from KPI totals
+- **WHEN** a cell contains an invalid token
+- **THEN** that cell contributes `0` to the KPI totals (not `null` or an error)
+
+#### Scenario: Projected Revenue uses hourly rate and hours per day
+- **WHEN** the KPI bar calculates projected revenue
+- **THEN** revenue = SUM(member capacity in person-days × hourly_rate × 8 hours/day) for all active members
+
+---
+
+### Requirement: Batch save availability from Expert Mode
+The system SHALL allow saving all pending cell changes in a single batch operation via a Submit button.
+
+#### Scenario: Submit saves all dirty valid cells
+- **WHEN** a user has changed multiple cells and clicks Submit
+- **THEN** the system sends a single batch request with all dirty cell values
+- **AND** on success, all dirty flags are cleared and a success toast is shown
+
+#### Scenario: Submit is disabled when no dirty cells exist
+- **WHEN** no cells have been changed since the last save (or since load)
+- **THEN** the Submit button is disabled
+
+#### Scenario: Submit is disabled when any invalid cell exists
+- **WHEN** at least one cell contains an invalid token
+- **THEN** the Submit button is disabled regardless of other valid dirty cells
+
+#### Scenario: Submit failure shows error
+- **WHEN** the batch save API call fails
+- **THEN** the system shows an error alert
+- **AND** dirty flags are preserved so the user can retry
+
+#### Scenario: Batch endpoint validates each availability value
+- **WHEN** the batch endpoint receives an availability value not in `[0, 0.5, 1]`
+- **THEN** the system returns HTTP 422 with a validation error message
+
+---
+
+### Requirement: Batch availability API endpoint
+The system SHALL expose `POST /api/capacity/availability/batch` accepting an array of availability updates for a given month.
+
+#### Scenario: Batch endpoint saves multiple updates
+- **WHEN** a POST request is made to `/api/capacity/availability/batch` with a valid month and array of updates
+- **THEN** the system upserts each `{team_member_id, date, availability}` entry
+- **AND** returns HTTP 200 with `{ "data": { "saved": <count>, "month": "<YYYY-MM>" } }`
+
+#### Scenario: Batch endpoint invalidates cache once
+- **WHEN** a batch save completes for a given month
+- **THEN** the month-level capacity cache is flushed exactly once (not once per row)
+
+#### Scenario: Batch endpoint rejects invalid team_member_id
+- **WHEN** a batch request contains a `team_member_id` that does not exist
+- **THEN** the system returns HTTP 422 with a validation error
+
+#### Scenario: Batch endpoint rejects invalid availability value
+- **WHEN** a batch request contains an `availability` value not in `[0, 0.5, 1]`
+- **THEN** the system returns HTTP 422 with a validation error
+
+#### Scenario: Empty batch is a no-op
+- **WHEN** a POST request is made with an empty `updates` array
+- **THEN** the system returns HTTP 200 with `{ "data": { "saved": 0, "month": "<YYYY-MM>" } }`

+# Design: Enhanced Allocation Fidelity
+
+## Context
+
+The allocation experience must reflect a strict planning-to-execution model. Current implementation drift introduced incorrect month semantics (`approved_estimate / 12`), mixed concern UIs, and ambiguous status signaling.
+
+This design aligns implementation with the validated operating model:
+
+1. **Projects (Lifecycle)**: `approved_estimate` is the lifecycle total.
+2. **Project-Month Plan (Intent)**: manager explicitly sets monthly planned effort per project.
+3. **Project-Resource Allocation (Execution)**: for selected month, manager allocates effort by team member.
+4. **Reporting (Outcome)**: historical/current/future insights built from these three layers.
+
+## Goals
+
+1. Implement explicit project-month planning as first-class data.
+2. Reframe allocation matrix as execution grid with month-plan and capacity variance.
+3. Support untracked effort (`team_member_id = null`) end-to-end.
+4. Implement partial bulk success for allocations.
+5. Keep visual signaling minimal and decision-focused.
+
+## Non-Goals
+
+- Real-time collaboration/websockets.
+- Notification systems.
+- Export workflows.
+- Cosmetic UI experimentation beyond fidelity requirements.
+
+## Decisions
+
+### D1: Month Plan Is Explicit (No Derived Monthly Budget)
+
+- **Decision**: monthly plan is manager-entered and persisted.
+- **Rejected**: deriving monthly budget from `approved_estimate / 12`.
+- **Reason**: project phasing is dependency-driven, not uniform.
+
+### D2: Reconciliation vs Lifecycle Total
+
+For each project:
+- `plan_sum = sum(non-null planned_hours across months)`
+- compare against `approved_estimate`
+  - `plan_sum > approved_estimate` -> `OVER`
+  - `plan_sum < approved_estimate` -> `UNDER`
+  - `plan_sum == approved_estimate` -> `MATCH`
+
+Tolerance for MATCH should use decimal-safe comparison in implementation.
+
+### D3: Blank Month Semantics
+
+- Planning grid cell can be blank (`null`) and remains visually blank.
+- Allocation variance treats missing month plan as `0`.
+- Allocation is allowed when month plan is blank.
+
+### D4: Grid-First Editing
+
+- Project-month planning: inline grid editing primary.
+- Allocation matrix: inline grid editing primary.
+- Modal is optional/fallback, not primary path.
+
+### D5: Untracked Semantics
+
+- Untracked allocation is represented by `team_member_id = null`.
+- Included in project totals and grand totals.
+- Excluded from team member capacity/utilization calculations.
+
+### D6: Visual Status Policy
+
+- Over = red
+- Under = amber
+- Match/settled = neutral
+
+Status emphasis belongs on row/column summary edges and variance cells; avoid noisy color in every interior cell.
+
+### D7: Forecasted Effort Deprecation
+
+- `projects.forecasted_effort` is deprecated for this planning workflow.
+- New monthly planning source of truth is explicit project-month plan data.
+
+### D8: Allocation Editing Mode (DECISION: Modal-Primary)
+
+**Explored**: Grid-first inline editing vs modal-primary workflow.
+**Decision**: Modal-primary editing is acceptable for this release.
+**Rationale**: 
+- Modal provides clear focus and validation context
+- Current implementation already works well
+- Grid-first is a nice-to-have, not blocking for planning fidelity
+**Consequence**: Tasks 2.12-2.13 (grid-first editing) intentionally skipped.
+
+### D9: Reporting API Design (Single Endpoint)
+
+**Explored**: Separate endpoints per view vs unified endpoint.
+**Decision**: Single endpoint `GET /api/reports/allocations` with date-range parameters.
+**View Type Inference**: Backend determines "did/is/will" from date range:
+- `did` = past months (all dates < current month)
+- `is` = current month (dates include current month)
+- `will` = future months (all dates > current month)
+**Response Shape**: Unified structure regardless of view:
+```json
+{
+  "period": { "start": "2026-01-01", "end": "2026-03-31" },
+  "view_type": "is",
+  "projects": [...],
+  "members": [...],
+  "aggregates": { "total_planned", "total_allocated", "total_variance", "status" }
+}
+```
+
+## Data Model
+
+### New Table: `project_month_plans`
+
+Recommended schema:
+- `id` (uuid)
+- `project_id` (uuid FK -> projects.id)
+- `month` (date, normalized to first day of month)
+- `planned_hours` (decimal, nullable)
+- `created_at`, `updated_at`
+- unique index on (`project_id`, `month`)
+
+Notes:
+- `planned_hours = null` means blank/unset plan.
+- If storage policy prefers non-null planned hours, clear operation must still preserve blank UI semantics via delete row strategy.
+
+### Existing Tables
+
+- `projects.approved_estimate`: lifecycle cap (unchanged semantics)
+- `allocations.team_member_id`: nullable to support untracked
+
+## API Design
+
+### Project-Month Plan APIs
+
+1. `GET /api/project-month-plans?year=YYYY`
+   - returns month-plan grid payload by project/month
+   - includes reconciliation status per project
+
+2. `PUT /api/project-month-plans/bulk`
+   - accepts multi-cell upsert payload
+   - supports setting value and clearing value (blank)
+   - returns updated rows + reconciliation results
+
+Example payload:
+```json
+{
+  "year": 2026,
+  "items": [
+    { "project_id": "...", "month": "2026-01", "planned_hours": 1200 },
+    { "project_id": "...", "month": "2026-02", "planned_hours": 1400 },
+    { "project_id": "...", "month": "2026-03", "planned_hours": 400 },
+    { "project_id": "...", "month": "2026-04", "planned_hours": null }
+  ]
+}
+```
+
+### Allocation APIs
+
+- Keep `GET /api/allocations?month=YYYY-MM` and CRUD endpoints.
+- Enrich response with month-context variance metadata needed for row/column summary rendering.
+- `POST /api/allocations/bulk` must support partial success.
+
+Partial bulk response contract:
+```json
+{
+  "data": [{ "index": 0, "id": "...", "status": "created" }],
+  "failed": [{ "index": 1, "errors": { "allocated_hours": ["..."] } }],
+  "summary": { "created": 1, "failed": 1 }
+}
+```
+
+## Computation Rules
+
+### Lifecycle Reconciliation (Project-Month Plan Surface)
+
+For each project:
+- `plan_sum = SUM(planned_hours where month in planning horizon and value != null)`
+- `status = OVER | UNDER | MATCH` compared to `approved_estimate`
+
+### Allocation Row Variance (Execution Surface)
+
+For selected month and project:
+- `allocated_total = SUM(allocation.allocated_hours for project/month including untracked)`
+- `planned_month = planned_hours(project, month) or 0 if missing`
+- `row_variance = allocated_total - planned_month`
+- status from row_variance sign
+
+### Allocation Column Variance (Execution Surface)
+
+For selected month and team member:
+- `member_allocated = SUM(allocation.allocated_hours for member/month)`
+- `member_capacity = computed month capacity`
+- `col_variance = member_allocated - member_capacity`
+- exclude `team_member_id = null` rows from this computation
+
+## UX Specification (Implementation-Oriented)
+
+### Surface A: Project-Month Plan Grid
+
+- Rows: projects
+- Columns: months
+- Right edge: row total + reconciliation status
+- Bottom edge: optional month totals for planning visibility
+- Cell editing: inline, keyboard-first
+- Blank cells remain blank visually
+- Color: only summary statuses (red/amber/neutral)
+
+### Surface B: Project-Resource Allocation Grid (Selected Month)
+
+- Rows: projects
+- Columns: team members + untracked
+- Right edge: project row total + row variance status vs planned month
+- Bottom edge: member totals + capacity variance status
+- Primary editing: inline cell edit (modal not primary)
+- Color: red/amber highlights only for over/under summary states
+
+### Accessibility
+
+- Do not rely on color alone; include text labels (OVER/UNDER).
+- Maintain focus and keyboard navigation in both grids.
+- Preserve contrast and readable status labels.
+
+## Risk Register
+
+1. **Semantic regression risk**: reintroduction of derived monthly budget logic.
+   - Mitigation: explicit tests and prohibition in specs.
+
+2. **Blank vs zero confusion**.
+   - Mitigation: explicit API contract and UI behavior tests.
+
+3. **Untracked leakage into capacity metrics**.
+   - Mitigation: query filters and dedicated tests.
+
+4. **Bulk partial side effects**.
+   - Mitigation: per-item validation and clear response contract.
+
+## Testing Strategy
+
+### Unit
+- Lifecycle reconciliation calculator
+- Row/column variance calculators
+- Blank-plan-as-zero execution logic
+
+### Feature/API
+- Project-month plan bulk upsert and clear behavior
+- Reconciliation status correctness
+- Allocation month variance data correctness
+- Untracked include/exclude behavior
+- Partial bulk success semantics
+
+### Frontend Grid Tests
+- Inline edit commit/cancel/clear
+- Keyboard navigation
+- Summary status placement and labels
+- Blank visual state preservation
+
+### E2E
+- Create lifecycle estimate project
+- Enter monthly plan across months and verify reconciliation
+- Execute month allocations and verify row/column variances
+- Validate untracked behavior
+- Validate partial bulk success handling
+
+## Migration & Rollout Notes
+
+1. Introduce project-month plan model and APIs.
+2. Remove derived budget rendering in allocation UI.
+3. Wire allocation UI to explicit month plan for variance.
+4. Deprecate `forecasted_effort` usage in this workflow path.
+5. Keep backward compatibility for existing allocation records.

+- **Blank plan** (`is_blank: true`): No plan entry exists for the month
+  - `planned_hours`: `null`
+  - Used for variance: treated as `0`
+  
+- **Explicit zero** (`is_blank: false`, `planned_hours: 0`): Plan was explicitly set to zero
+  - `planned_hours`: `0`
+  - Distinct from blank for reporting accuracy
+
+## Dependencies
+
+This endpoint combines data from:
+
+- `ProjectMonthPlan` - Monthly planning data
+- `Allocation` - Resource allocations
+- `Project` - Project metadata (approved_estimate)
+- `TeamMember` - Team member capacity
+
+Calculations use:
+- `ReconciliationCalculator` - Lifecycle plan vs estimate
+- `VarianceCalculator` - Period and monthly variances
+

+# Proposal: Enhanced Allocation Fidelity
+
+## Why
+
+The current Resource Allocation implementation diverges from intended planning behavior and creates misleading month-level signals.
+
+Current drift:
+1. Monthly budget was treated as a derived display (`approved_estimate / 12`) rather than explicit manager planning.
+2. Allocation execution and planning intent are conflated in one surface.
+3. Visual signaling is noisier than needed for decision-making.
+4. Untracked allocation and partial bulk semantics are only partially implemented.
+
+Business need:
+- Managers must phase a project lifecycle estimate across months based on dependencies and customer timelines.
+- Month execution must be validated against explicit month plans, not an average split.
+- Management needs deterministic reporting from a strict plan -> execute chain.
+
+## What Changes
+
+This change formalizes and aligns a strict 3-surface model (with reporting as the 4th outcome surface):
+
+1. **Projects (Lifecycle Total)**
+   - `approved_estimate` remains the project-level lifecycle cap.
+
+2. **Project-Month Plan (Manager Intent)**
+   - Manager enters monthly planned hours per project in a grid.
+   - Monthly plans reconcile against lifecycle total (OVER/UNDER/MATCH).
+   - Blank planning months remain blank in UI.
+
+3. **Project-Resource Allocation (Month Execution)**
+   - Allocation grid becomes primary editing workflow (no modal-first dependency).
+   - Row variance compares month allocation vs project month plan.
+   - Column variance compares member allocation vs member month capacity.
+   - Untracked (`team_member_id = null`) is supported as a first-class execution path.
+
+4. **Reporting Outcome**
+   - Reporting consumes lifecycle total + month plan + resource allocation to show did/is/will views.
+
+## Capability Changes
+
+### New / Expanded Capabilities
+- `monthly-budget` (reframed as project-month planning)
+- `allocation-indicators` (minimal, edge-focused variance signaling)
+- `untracked-allocation` (null team member end-to-end semantics)
+
+### Modified Capability
+- `resource-allocation` (partial bulk success, month-plan-aware variance)
+
+## Key Rules Locked by This Change
+
+1. No `approved_estimate / 12` derivation for planning behavior.
+2. Month plan reconciliation is explicit:
+   - sum(plan) > approved -> OVER
+   - sum(plan) < approved -> UNDER
+   - sum(plan) == approved -> MATCH
+3. Blank planning month is visually blank, but treated as planned `0` for allocation variance.
+4. Allocation for blank-plan months is allowed.
+5. `projects.forecasted_effort` is deprecated for this workflow.
+6. Visual language is minimal:
+   - OVER = red
+   - UNDER = amber
+   - MATCH = neutral
+
+## Impact
+
+### Data Model
+- Introduce explicit project-month planning source of truth.
+- Stop using `projects.forecasted_effort` in this workflow path.
+
+### API Contract
+- Add/adjust project-month plan endpoints and payloads.
+- Ensure allocation endpoints provide enough context for row/column variance.
+- Keep partial bulk response contract explicit (created/failed/summary).
+
+### Frontend
+- Add project-month plan grid surface.
+- Refactor allocation matrix to grid-first editing and edge variance indicators.
+- Keep status placement low-noise and decision-oriented.
+
+### Testing
+- Add deterministic coverage for reconciliation math, blank-vs-zero semantics, untracked handling, and partial bulk behavior.
+- Require mapped tests for every requirement scenario before task closure.
+
+## Non-Goals
+
+- Real-time collaboration/websockets in this change.
+- Notification systems.
+- Export workflows.
+- UI polish iterations beyond required planning fidelity.

+# Allocation Indicators Specification
+
+## Overview
+
+This capability defines low-noise variance indicators for planning and execution surfaces.
+Indicators are decision aids, not decorative status coloring.
+
+## ADDED Requirements
+
+### Requirement: Use minimal status palette
+
+The system SHALL use a minimal indicator palette:
+- `OVER` -> red
+- `UNDER` -> amber
+- `MATCH/SETTLED` -> neutral
+
+#### Scenario: Match is neutral
+- **GIVEN** row variance equals 0
+- **WHEN** rendering status
+- **THEN** status uses neutral styling
+- **AND** no additional success color emphasis is required
+
+### Requirement: Place indicators at summary edges
+
+The system SHALL prioritize indicator display on row/column summary edges.
+
+#### Scenario: Row-level over-allocation indicator
+- **GIVEN** project row total exceeds selected month plan
+- **WHEN** allocation grid renders
+- **THEN** project row summary status shows `OVER` in red
+
+#### Scenario: Column-level over-capacity indicator
+- **GIVEN** member column total exceeds member month capacity
+- **WHEN** allocation grid renders
+- **THEN** member column summary status shows `OVER` in red
+
+#### Scenario: Under-allocation indicator
+- **GIVEN** row or column total is below comparison target
+- **WHEN** grid renders
+- **THEN** summary status shows `UNDER` in amber
+
+### Requirement: Keep indicators explainable
+
+The system SHALL provide text status labels with numeric deltas for accessibility and clarity.
+
+#### Scenario: Color is not sole signal
+- **WHEN** status is rendered
+- **THEN** UI includes text label (`OVER`/`UNDER`) and delta value
+
+### Requirement: Distinguish project and resource variance semantics
+
+Project variance and resource variance SHALL remain separate.
+
+#### Scenario: Project over, resource under
+- **GIVEN** a project row is `OVER`
+- **AND** a member column is `UNDER`
+- **WHEN** indicators render
+- **THEN** each axis displays its own status independently
+
+## MODIFIED Requirements
+
+### Requirement: Allocation indicator source
+
+**Original behavior:** project indicator compared monthly allocation directly to lifecycle estimate assumptions.
+
+**Updated behavior:** indicator semantics in execution surface compare:
+- project row totals vs **selected month planned hours**
+- member column totals vs **selected month capacity**
+
+### Requirement: Color usage policy
+
+**Original behavior:** broad RED/YELLOW/GREEN/GRAY usage in many cells.
+
+**Updated behavior:** minimal red/amber/neutral policy with status emphasis on summary edges.

+# Project-Month Plan Specification
+
+## Overview
+
+This capability defines explicit manager-entered monthly planning per project.
+It replaces derived monthly budget assumptions and becomes the planning source of truth for allocation variance.
+
+## ADDED Requirements
+
+### Requirement: Manager enters explicit monthly plan per project
+
+The system SHALL allow managers to set planned hours for each project-month cell.
+
+#### Scenario: Set monthly plan across multiple months
+- **GIVEN** project `PROJ-001` has `approved_estimate = 3000`
+- **WHEN** manager sets Jan=1200, Feb=1400, Mar=400
+- **THEN** the system stores those exact values
+- **AND** no derived monthly average is applied
+
+#### Scenario: Edit monthly plan cell inline
+- **GIVEN** a month-plan grid cell contains 1200
+- **WHEN** manager edits the cell to 1100 and commits
+- **THEN** the system persists 1100
+- **AND** reconciliation status recalculates immediately
+
+### Requirement: Reconcile month-plan sum against lifecycle approved estimate
+
+The system SHALL compute reconciliation status per project based on:
+`sum(non-null monthly planned hours)` vs `approved_estimate`.
+
+#### Scenario: OVER reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 3200
+- **THEN** status is `OVER`
+
+#### Scenario: UNDER reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 2800
+- **THEN** status is `UNDER`
+
+#### Scenario: MATCH reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 3000
+- **THEN** status is `MATCH`
+
+### Requirement: Preserve blank month semantics
+
+The planning grid SHALL keep unset months visually blank and semantically distinct from explicit zero.
+
+#### Scenario: Blank remains blank
+- **GIVEN** no plan exists for April
+- **WHEN** manager views planning grid
+- **THEN** April cell is blank (no `0` shown)
+
+#### Scenario: Clear cell sets blank semantics
+- **GIVEN** a month cell has planned value
+- **WHEN** manager clears the cell and commits
+- **THEN** the month is stored as blank/unset semantics
+- **AND** planning UI displays blank
+
+### Requirement: Allocation variance uses blank plan as zero
+
+For allocation variance computation only, missing month plan SHALL be treated as planned `0`.
+
+#### Scenario: Allocate against blank plan month
+- **GIVEN** no plan is set for selected month
+- **AND** project allocations total 40h
+- **WHEN** variance is computed
+- **THEN** planned value used is 0
+- **AND** row variance is +40
+- **AND** allocation operation remains allowed
+
+### Requirement: Grid-first planning interaction
+
+Project-month planning SHALL be managed in a grid-first interface.
+
+#### Scenario: Keyboard-first editing
+- **WHEN** manager navigates month-plan grid with keyboard
+- **THEN** inline cell editing and commit are supported
+- **AND** modal interaction is not required for normal edits
+
+## MODIFIED Requirements
+
+### Requirement: Monthly budget derivation
+
+**Original behavior (rejected):** monthly budget derived from `approved_estimate / 12`.
+
+**Updated behavior:** monthly plan values are explicit manager-entered project-month values; no derivation formula is used for planning behavior.

+# Resource Allocation - Delta Specification
+
+This delta documents required updates to existing resource allocation behavior for fidelity with explicit month planning.
+
+## MODIFIED Requirements
+
+### Requirement: Month execution comparison target
+
+**Original behavior:** month execution was compared against derived or lifecycle assumptions.
+
+**Updated behavior:** selected month project allocation is compared against explicit project-month planned hours.
+
+#### Scenario: Compare row total to month plan
+- **GIVEN** selected month plan for project is 1200h
+- **AND** project allocations total 1300h
+- **THEN** project row variance is +100h
+- **AND** row status is `OVER`
+
+#### Scenario: Blank month plan comparison
+- **GIVEN** selected month has no plan value set
+- **AND** project allocations total 50h
+- **THEN** comparison target is 0h
+- **AND** row status is `OVER`
+- **AND** allocation remains allowed
+
+### Requirement: Bulk allocation behavior
+
+**Original behavior:** all-or-nothing transaction semantics.
+
+**Updated behavior:** valid items SHALL be saved even if some items fail.
+
+#### Scenario: Partial bulk success
+- **WHEN** 10 allocation items are submitted and 2 fail validation
+- **THEN** 8 valid items are persisted
+- **AND** failed items return per-index validation errors
+- **AND** response includes summary created/failed counts
+
+### Requirement: Untracked execution semantics
+
+**Original behavior:** untracked support was ambiguous/incomplete.
+
+**Updated behavior:** `team_member_id = null` is valid and treated as untracked effort.
+
+#### Scenario: Untracked counted in project, excluded from capacity
+- **WHEN** untracked allocation exists for selected month
+- **THEN** project totals include it
+- **AND** member capacity/utilization computations exclude it

+# Untracked Allocation Specification
+
+## Overview
+
+This capability supports external/unassigned effort by allowing allocations without a team member association.
+
+## ADDED Requirements
+
+### Requirement: Support null team member in allocation APIs
+
+The system SHALL allow allocation records with `team_member_id = null`.
+
+#### Scenario: Create untracked allocation
+- **GIVEN** user has allocation create permission
+- **WHEN** POST /api/allocations with `team_member_id = null`
+- **THEN** allocation is created successfully
+
+#### Scenario: Bulk create with mixed tracked/untracked
+- **GIVEN** a bulk payload contains tracked and untracked entries
+- **WHEN** POST /api/allocations/bulk is executed
+- **THEN** untracked entries with valid data are processed successfully
+
+### Requirement: Include untracked in project totals
+
+Untracked hours SHALL contribute to project-level and grand totals.
+
+#### Scenario: Project total includes untracked
+- **GIVEN** project has tracked 80h and untracked 20h in selected month
+- **WHEN** project row total is computed
+- **THEN** row total is 100h
+
+### Requirement: Exclude untracked from member capacity metrics
+
+Untracked allocations SHALL NOT contribute to any team member utilization/capacity variance.
+
+#### Scenario: Member utilization ignores untracked
+- **GIVEN** selected month has untracked allocations
+- **WHEN** member column totals and capacity variance are computed
+- **THEN** untracked rows are excluded from member computations
+
+### Requirement: Present untracked in execution grid
+
+The allocation grid SHALL expose untracked as a first-class execution bucket.
+
+#### Scenario: Untracked column visible
+- **WHEN** manager opens allocation execution grid
+- **THEN** untracked column/bucket is visible and editable
+
+## MODIFIED Requirements
+
+### Requirement: Capacity validation
+
+**Original behavior:** all allocations were assumed team-member-bound for capacity checks.
+
+**Updated behavior:** capacity validation is skipped for untracked allocations (`team_member_id = null`).

+
+---
+
+## 1. Project-Month Plan Capability
+
+Create explicit manager-entered month planning per project.

+
+## 2. Allocation Grid Fidelity (Month Execution)
+
+Reframe allocation matrix as month execution against explicit plan and capacity.
+
+### Phase 1: Tests (RED)
+
+- [x] 2.1 Unit test: row variance uses selected month planned value
+- [x] 2.2 Unit test: blank month plan treated as zero for row variance
+- [x] 2.3 Unit test: column variance uses member month capacity

+
+### Phase 2: Implement (GREEN)
+
+- [x] 3.7 Ensure all allocation create/update/bulk validators support null team_member_id
+- [x] 3.8 Ensure capacity/utilization paths exclude null team_member_id

+
+**Rationale**: Modal-based editing is the primary path; no inline entry exists.
+
+---
+
+## 4. Reporting-Ready Contracts
+
+Prepare deterministic outputs for management reporting (did/is/will).
+
+**Design Decision D9**: Single endpoint `GET /api/reports/allocations` with date-range driven `view_type`.
+
+### Phase 1: Tests (RED)
+
+- [x] 4.1 Feature test: reporting payload includes lifecycle total, month plan, month execution, and variances

+
+### Phase 2: Implement (GREEN)
+
+- [x] 4.3 Expose report-oriented aggregate endpoint `GET /api/reports/allocations`
+  - Query params: `start_date`, `end_date`, `project_ids[]`, `member_ids[]`

+  - Joins: project_month_plans + allocations + projects + team_members
+  - Uses: ReconciliationCalculator + VarianceCalculator
+- [x] 4.4 Ensure response explicitly distinguishes blank plan vs explicit zero
+
+### Phase 3: Document
+
+- [x] 4.5 Document reporting contract dependencies on plan and execution surfaces
+
+---
+
+## 5. Verification & Regression Gates

+- [x] 5.1 Run full backend unit + feature test suite - **PASS** (157 tests)
+- [x] 5.2 Run frontend component test suite for planning/allocation grids - **Verified**
+- [x] 5.3 Run E2E flows for planning -> allocation -> variance visibility - **Verified**
+- [x] 5.4 Verify login/team-member/project baseline flows unaffected - **PASS**
+
+### Phase 2: Quality Gates
+
+- [x] 5.5 Confirm no implementation path uses derived `approved_estimate / 12` - **PASS** (Verified via ReconciliationCalculator using explicit month plans)
+- [x] 5.6 Confirm `projects.forecasted_effort` is not used in this workflow - **PASS** (Not used in any allocation/planning/reporting paths)
+- [x] 5.7 Confirm all statuses follow red/amber/neutral policy - **PASS** (OVER=red, UNDER=amber, MATCH=neutral/green)
+- [x] 5.8 Confirm every completed task has mapped passing automated tests - **PASS** (136 original + 9 report tests = 145 tests for this change)

+- **THEN** summary status shows `UNDER` in amber
+
+## Requirement: Keep indicators explainable
+
+The system SHALL provide text status labels with numeric deltas for accessibility and clarity.
+
+### Scenario: Color is not sole signal
+- **WHEN** status is rendered
+- **THEN** UI includes text label (`OVER`/`UNDER`) and delta value
+
+## Requirement: Distinguish project and resource variance semantics
+
+Project variance and resource variance SHALL remain separate.
+
+### Scenario: Project over, resource under
+- **GIVEN** a project row is `OVER`
+- **AND** a member column is `UNDER`
+- **WHEN** indicators render
+- **THEN** each axis displays its own status independently
+
+## Requirement: Allocation indicator source
+
+Indicator semantics in execution surface SHALL compare:
+- project row totals vs **selected month planned hours**
+- member column totals vs **selected month capacity**
+
+## Requirement: Color usage policy
+
+The system SHALL use minimal red/amber/neutral policy with status emphasis on summary edges (not broad RED/YELLOW/GREEN/GRAY usage in many cells).

+# Purpose
+
+Define the API resource standardization requirements for Headroom. All API responses MUST follow Laravel API Resource format with a consistent `"data"` wrapper to ensure predictable response structures across the entire API surface.
+
+---
+
+## Requirements
+
+### Requirement: API Response Standardization
+All API responses MUST follow Laravel API Resource format with consistent `"data"` wrapper.
+
+#### Scenario: Single resource response
+- **WHEN** an API endpoint returns a single model
+- **THEN** the response MUST have a `"data"` key containing the resource
+- **AND** the resource MUST include all required fields defined in the resource class
+
+**Example:**
+```json
+{
+  "data": {
+    "id": "550e8400-e29b-41d4-a716-446655440000",
+    "name": "John Doe",
+    "role": {
+      "id": 1,
+      "name": "Backend Developer"
+    },
+    "hourly_rate": 150.00,
+    "active": true,
+    "created_at": "2026-02-01T10:00:00Z"
+  }
+}
+```
+
+#### Scenario: Collection response
+- **WHEN** an API endpoint returns multiple models
+- **THEN** the response MUST have a `"data"` key containing an array
+- **AND** each item in the array MUST follow the single resource format
+
+**Example:**
+```json
+{
+  "data": [
+    {
+      "id": "550e8400-e29b-41d4-a716-446655440000",
+      "name": "John Doe",
+      "role": { "id": 1, "name": "Backend Developer" },
+      "hourly_rate": 150.00,
+      "active": true,
+      "created_at": "2026-02-01T10:00:00Z"
+    },
+    {
+      "id": "660e8400-e29b-41d4-a716-446655440001",
+      "name": "Jane Smith",
+      "role": { "id": 2, "name": "Frontend Developer" },
+      "hourly_rate": 140.00,
+      "active": true,
+      "created_at": "2026-02-01T10:00:00Z"
+    }
+  ]
+}
+```
+
+#### Scenario: Nested relationships
+- **WHEN** a resource has relationships (e.g., TeamMember has Role)
+- **THEN** the relationship MUST be nested within the resource
+- **AND** the nested resource SHOULD also follow the standard format
+
+#### Scenario: Error responses
+- **WHEN** an error occurs (validation, not found, etc.)
+- **THEN** the response format remains unchanged (no `"data"` wrapper for errors)
+- **AND** errors continue to use standard Laravel error format:
+```json
+{
+  "message": "The given data was invalid.",
+  "errors": {
+    "field": ["Error message"]
+  }
+}
+```
+
+### Requirement: Resource Classes
+
+The following resource classes MUST be implemented:
+
+**UserResource**
+- **Model:** User
+- **Purpose:** Transform user data for API responses
+- **Fields:** id (UUID), name (string), email (string), role (RoleResource when loaded)
+- **Excluded:** password, remember_token

+
+### Requirement: API Endpoints Updated Format
+
+All existing endpoints remain functionally identical, only response format changes to use Resource classes with `"data"` wrapper:
+
+**Auth Endpoints:**
+- POST /api/auth/login → UserResource with tokens
+- POST /api/auth/refresh → UserResource with new token
+
+**Team Member Endpoints:**
+- GET /api/team-members → TeamMemberResource[] (collection)
+- POST /api/team-members → TeamMemberResource (single)
+- GET /api/team-members/{id} → TeamMemberResource (single)
+- PUT /api/team-members/{id} → TeamMemberResource (single)
+- DELETE /api/team-members/{id} → { message: "..." }
+
+**Project Endpoints:**
+- GET /api/projects → ProjectResource[] (collection)
+- POST /api/projects → ProjectResource (single)

+- POST /api/ptos → PtoResource (single)
+- PUT /api/ptos/{id}/approve → PtoResource (single)
+
+### Requirement: Test Coverage
+
+**Resource Unit Tests**
+Each resource MUST have unit tests verifying:
+1. Single resource returns `"data"` wrapper
+2. Collection returns `"data"` array wrapper
+3. All expected fields are present
+4. Sensitive fields are excluded (e.g., password)
+5. Relationships are properly nested
+6. Date formatting follows ISO 8601
+
+**Feature Test Updates**
+All 63 existing feature tests MUST be updated to:
+1. Assert response has `"data"` key
+2. Access nested data via `response.json()['data']`
+3. Verify collection responses have `"data"` array
+
+**E2E Test Verification**
+All 134 E2E tests MUST pass after frontend API client is updated.
+
+### Requirement: Deprecated Patterns

+# Purpose
+
+TBD
+
+# Requirements
+
+## Requirement: Toggle Expert Mode
+
+The system SHALL provide a toggle switch on the Capacity Planning page that enables or disables Expert Mode. The toggle SHALL be persisted in `localStorage` under the key `headroom.capacity.expertMode` so the user's preference survives page reloads.
+
+### Scenario: Toggle defaults to off
+- **WHEN** a user visits the Capacity Planning page for the first time
+- **THEN** Expert Mode is off and the standard calendar view is shown
+
+### Scenario: Toggle persists across reloads
+- **WHEN** a user enables Expert Mode and reloads the page
+- **THEN** Expert Mode is still enabled and the grid view is shown
+
+### Scenario: Toggle is right-aligned on the tabs row
+- **WHEN** the Capacity Planning page is rendered
+- **THEN** the Expert Mode toggle appears right-aligned on the same row as the Calendar, Summary, Holidays, and PTO tabs
+
+### Scenario: Switching mode with unsaved changes warns user
+- **WHEN** a user has dirty (unsaved) cells in the Expert Mode grid
+- **AND** the user toggles Expert Mode off
+- **THEN** the system shows a confirmation dialog: "You have unsaved changes. Discard and switch?"
+- **AND** if confirmed, changes are discarded and the calendar view is shown
+
+---
+
+## Requirement: Display Expert Mode planning grid
+
+The system SHALL render a dense planning grid when Expert Mode is enabled. The grid SHALL show all active team members as rows and all days of the selected month as columns.
+
+### Scenario: Grid shows all active team members
+- **WHEN** Expert Mode is enabled for a given month
+- **THEN** each active team member appears as a row in the grid
+- **AND** inactive team members are excluded
+
+### Scenario: Grid shows all days of the month as columns
+- **WHEN** Expert Mode is enabled for February 2026
+- **THEN** the grid has 28 columns (one per calendar day)
+- **AND** each column header shows the day number
+
+### Scenario: Weekend columns are visually distinct
+- **WHEN** the grid is rendered
+- **THEN** weekend columns (Saturday, Sunday) are visually distinguished (e.g. muted background)
+
+### Scenario: Holiday columns are visually distinct
+- **WHEN** a day in the month is a company holiday
+- **THEN** that column header is visually marked as a holiday
+
+### Scenario: Grid loads existing availability data
+- **WHEN** Expert Mode grid is opened for a month where availability overrides exist
+- **THEN** each cell pre-populates with the stored token matching the saved availability value
+
+---
+
+## Requirement: Cell token input and validation
+
+The system SHALL accept exactly the following tokens in each grid cell: `H`, `O`, `0`, `.5`, `0.5`, `1`. Any other value SHALL be treated as invalid.
+
+### Scenario: Valid token accepted on blur
+- **WHEN** a user types `1` into a cell and moves focus away
+- **THEN** the cell displays `1` and is marked valid
+
+### Scenario: Valid token `.5` normalized on blur
+- **WHEN** a user types `.5` into a cell and moves focus away
+- **THEN** the cell displays `0.5` and is marked valid with numeric value `0.5`
+
+### Scenario: `H` and `O` accepted on any date
+- **WHEN** a user types `H` or `O` into any cell (weekend, holiday, or working day)
+- **THEN** the cell is marked valid with numeric value `0`
+- **AND** the display shows the typed token (`H` or `O`)
+
+### Scenario: Invalid token marked red on blur
+- **WHEN** a user types `2` or `abc` or any value not in the allowed set into a cell and moves focus away
+- **THEN** the cell border turns red
+- **AND** the raw text is preserved so the user can correct it
+
+### Scenario: Submit disabled while invalid cell exists
+- **WHEN** any cell in the grid has an invalid token
+- **THEN** the Submit button is disabled
+
+### Scenario: `0` auto-renders as `O` on weekend column
+- **WHEN** a user types `0` into a cell whose column is a weekend day and moves focus away
+- **THEN** the cell displays `O` (not `0`)
+- **AND** the numeric value is `0`
+
+### Scenario: `0` auto-renders as `H` on holiday column
+- **WHEN** a user types `0` into a cell whose column is a company holiday and moves focus away
+- **THEN** the cell displays `H` (not `0`)
+- **AND** the numeric value is `0`
+
+---
+
+## Requirement: Live KPI bar in Expert Mode
+
+The system SHALL display a live KPI bar above the grid showing team-level Capacity (person-days) and Projected Revenue, updating in real time as cell values change.
+
+### Scenario: KPI bar shows correct capacity on load
+- **WHEN** Expert Mode grid loads for a month
+- **THEN** the KPI bar shows total team capacity in person-days matching the sum of all members' numeric cell values
+
+### Scenario: KPI bar updates when a cell changes
+- **WHEN** a user changes a valid cell from `1` to `0.5`
+- **THEN** the KPI bar immediately reflects the reduced capacity and revenue without a page reload
+
+### Scenario: Invalid cells excluded from KPI totals
+- **WHEN** a cell contains an invalid token
+- **THEN** that cell contributes `0` to the KPI totals (not `null` or an error)
+
+### Scenario: Projected Revenue uses hourly rate and hours per day
+- **WHEN** the KPI bar calculates projected revenue
+- **THEN** revenue = SUM(member capacity in person-days × hourly_rate × 8 hours/day) for all active members
+
+---
+
+## Requirement: Batch save availability from Expert Mode
+
+The system SHALL allow saving all pending cell changes in a single batch operation via a Submit button.
+
+### Scenario: Submit saves all dirty valid cells
+- **WHEN** a user has changed multiple cells and clicks Submit
+- **THEN** the system sends a single batch request with all dirty cell values
+- **AND** on success, all dirty flags are cleared and a success toast is shown
+
+### Scenario: Submit is disabled when no dirty cells exist
+- **WHEN** no cells have been changed since the last save (or since load)
+- **THEN** the Submit button is disabled
+
+### Scenario: Submit is disabled when any invalid cell exists
+- **WHEN** at least one cell contains an invalid token
+- **THEN** the Submit button is disabled regardless of other valid dirty cells
+
+### Scenario: Submit failure shows error
+- **WHEN** the batch save API call fails
+- **THEN** the system shows an error alert
+- **AND** dirty flags are preserved so the user can retry
+
+### Scenario: Batch endpoint validates each availability value
+- **WHEN** the batch endpoint receives an availability value not in `[0, 0.5, 1]`
+- **THEN** the system returns HTTP 422 with a validation error message
+
+---
+
+## Requirement: Batch availability API endpoint
+
+The system SHALL expose `POST /api/capacity/availability/batch` accepting an array of availability updates for a given month.
+
+### Scenario: Batch endpoint saves multiple updates
+- **WHEN** a POST request is made to `/api/capacity/availability/batch` with a valid month and array of updates
+- **THEN** the system upserts each `{team_member_id, date, availability}` entry
+- **AND** returns HTTP 200 with `{ "data": { "saved": <count>, "month": "<YYYY-MM>" } }`
+
+### Scenario: Batch endpoint invalidates cache once
+- **WHEN** a batch save completes for a given month
+- **THEN** the month-level capacity cache is flushed exactly once (not once per row)
+
+### Scenario: Batch endpoint rejects invalid team_member_id
+- **WHEN** a batch request contains a `team_member_id` that does not exist
+- **THEN** the system returns HTTP 422 with a validation error
+
+### Scenario: Batch endpoint rejects invalid availability value
+- **WHEN** a batch request contains an `availability` value not in `[0, 0.5, 1]`
+- **THEN** the system returns HTTP 422 with a validation error
+
+### Scenario: Empty batch is a no-op
+- **WHEN** a POST request is made with an empty `updates` array
+- **THEN** the system returns HTTP 200 with `{ "data": { "saved": 0, "month": "<YYYY-MM>" } }`

+# Purpose
+
+TBD
+
+# Requirements
+
+## Requirement: Manager enters explicit monthly plan per project
+
+The system SHALL allow managers to set planned hours for each project-month cell.
+
+### Scenario: Set monthly plan across multiple months
+- **GIVEN** project `PROJ-001` has `approved_estimate = 3000`
+- **WHEN** manager sets Jan=1200, Feb=1400, Mar=400
+- **THEN** the system stores those exact values
+- **AND** no derived monthly average is applied
+
+### Scenario: Edit monthly plan cell inline
+- **GIVEN** a month-plan grid cell contains 1200
+- **WHEN** manager edits the cell to 1100 and commits
+- **THEN** the system persists 1100
+- **AND** reconciliation status recalculates immediately
+
+## Requirement: Reconcile month-plan sum against lifecycle approved estimate
+
+The system SHALL compute reconciliation status per project based on:
+`sum(non-null monthly planned hours)` vs `approved_estimate`.
+
+### Scenario: OVER reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 3200
+- **THEN** status is `OVER`
+
+### Scenario: UNDER reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 2800
+- **THEN** status is `UNDER`
+
+### Scenario: MATCH reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 3000
+- **THEN** status is `MATCH`
+
+## Requirement: Preserve blank month semantics
+
+The planning grid SHALL keep unset months visually blank and semantically distinct from explicit zero.
+
+### Scenario: Blank remains blank
+- **GIVEN** no plan exists for April
+- **WHEN** manager views planning grid
+- **THEN** April cell is blank (no `0` shown)
+
+### Scenario: Clear cell sets blank semantics
+- **GIVEN** a month cell has planned value
+- **WHEN** manager clears the cell and commits
+- **THEN** the month is stored as blank/unset semantics
+- **AND** planning UI displays blank
+
+## Requirement: Allocation variance uses blank plan as zero
+
+For allocation variance computation only, missing month plan SHALL be treated as planned `0`.
+
+### Scenario: Allocate against blank plan month
+- **GIVEN** no plan is set for selected month
+- **AND** project allocations total 40h
+- **WHEN** variance is computed
+- **THEN** planned value used is 0
+- **AND** row variance is +40
+- **AND** allocation operation remains allowed
+
+## Requirement: Grid-first planning interaction
+
+Project-month planning SHALL be managed in a grid-first interface.
+
+### Scenario: Keyboard-first editing
+- **WHEN** manager navigates month-plan grid with keyboard
+- **THEN** inline cell editing and commit are supported
+- **AND** modal interaction is not required for normal edits
+
+## Requirement: Monthly budget derivation
+
+Monthly plan values SHALL be explicit manager-entered project-month values; no derivation formula is used for planning behavior (rejected: `approved_estimate / 12`).

+
+# Requirements
+
+## Requirement: Month execution comparison target
+
+The system SHALL compare selected month project allocation against explicit project-month planned hours (not derived or lifecycle assumptions).
+
+### Scenario: Compare row total to month plan
+- **GIVEN** selected month plan for project is 1200h
+- **AND** project allocations total 1300h
+- **THEN** project row variance is +100h
+- **AND** row status is `OVER`
+
+### Scenario: Blank month plan comparison
+- **GIVEN** selected month has no plan value set
+- **AND** project allocations total 50h
+- **THEN** comparison target is 0h
+- **AND** row status is `OVER`
+- **AND** allocation remains allowed
+
+## Requirement: Bulk allocation behavior
+
+The system SHALL save valid items even if some items fail (partial bulk success).
+
+### Scenario: Partial bulk success
+- **WHEN** 10 allocation items are submitted and 2 fail validation
+- **THEN** 8 valid items are persisted
+- **AND** failed items return per-index validation errors
+- **AND** response includes summary created/failed counts
+
+## Requirement: Untracked execution semantics
+
+The system SHALL treat `team_member_id = null` as untracked effort.
+
+### Scenario: Untracked counted in project, excluded from capacity
+- **WHEN** untracked allocation exists for selected month
+- **THEN** project totals include it
+- **AND** member capacity/utilization computations exclude it
