+# 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
+
+---
+
+## Earlier Decisions
+
+See `design.md` sections D1-D7 for original design decisions.

+## 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" | ,
+ 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 }
+ ]

+ }
+}
+```
+
+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
+- **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": , "month": "" } }`
+
+#### 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": "" } }`
