# Coastal Timesheet v2 — Expert Panel Audit & Fix Task

## App Location
- Frontend source: `/opt/code-collab/projects/active/ba94ec47/v2/frontend/`
- Backend source: `/opt/code-collab/projects/active/ba94ec47/v2/backend/`
- Docker: `/opt/code-collab/projects/active/ba94ec47/v2/docker/`
- Live at: `http://100.94.106.120:8080` (Tailscale)
- Admin login: `admin@coastal.com` / `CoastalAdmin2026!`

## Critical Bugs to Fix

### Bug 1: Timezone causes wrong day names (CRITICAL)
**File:** `frontend/src/components/DayCard.jsx` and `frontend/src/pages/Timesheet.jsx`
**Problem:** `new Date("2026-02-10")` parses as UTC midnight. In US timezones, `getDay()` returns previous day (Sunday instead of Monday).
**Fix:** Use `new Date(date + 'T00:00:00')` (local) or split the date string and construct manually. Apply everywhere dates are parsed from `YYYY-MM-DD` strings.
**Also fix in:** `WeekNavigator.jsx`, `History.jsx`, anywhere `new Date(dateString)` is used with YYYY-MM-DD format.

### Bug 2: Pre-filled entries can't be edited or deleted
**Problem:** User reports entries exist that can't be modified. Likely the `disabled={isLocked}` check is triggering incorrectly, or the auto-save/PUT endpoint has an issue.
**Check:** `Timesheet.jsx` — `isLocked` logic, `handleEntryChange`, `handleDeleteEntry`. Also check if the seed created phantom entries.

### Bug 3: Week label mismatch  
**Problem:** Shows "Feb 9 - Feb 15" but starts with Sunday Feb 8. The header says one range but cards show different dates.
**Fix:** Ensure `WeekNavigator` header range and `getWeekDates()` output are consistent — both Mon-Sun.

## Feature Requirements

### Multiple homeowners per day (already partially works)
- The "Add Entry" button exists in DayCard but verify it works end-to-end
- Each day should support unlimited entries (different homeowners, different hours)
- Total hours per day should sum all entries

### Admin Reporting (needs frontend)
Backend already has these endpoints — need admin UI:
- `GET /api/admin/timesheets` — list all employee timesheets with filters
- `GET /api/admin/timesheets/:id` — detail view of specific timesheet
- `GET /api/admin/reports` — reporting with date range, employee, homeowner filters
- `GET /api/admin/reports/pdf` — PDF export

### Admin Panel Enhancements Needed
1. **Employee Timesheet Browser** — Admin can select any employee and see their timesheet for any week
2. **Filters** — by employee, date range, homeowner, status (draft/submitted/approved/rejected)
3. **Bulk actions** — approve/reject multiple timesheets at once
4. **Export** — CSV/PDF export of filtered data
5. **Dashboard summary** — total hours this week/month, pending reviews count, recent submissions

## Quality Standards
- Mobile-first, responsive design
- Dark mode support throughout
- Loading states for all async operations
- Error handling with user-friendly messages
- No console errors
- All dates display correctly in US timezones
- Professional, polished UI suitable for 40+ employees
