Added three Garmin API endpoints for token management:
- POST /api/garmin/tokens: Accepts oauth1, oauth2, expires_at;
encrypts tokens using AES-256-GCM; stores in user record;
returns daysUntilExpiry
- DELETE /api/garmin/tokens: Clears encrypted tokens from user
record and sets garminConnected to false
- GET /api/garmin/status: Returns connection status, days until
expiry, expired flag, and warning level (critical ≤7 days,
warning 8-14 days)
All endpoints use withAuth() middleware for authentication.
Added 26 tests covering encryption, validation, auth, and
warning level thresholds.
Also added pb_data/ to .gitignore for PocketBase data.

Add specific fetchers for HRV, Body Battery, and Intensity Minutes
to enable real biometric data collection from Garmin Connect API.
Functions added:
- fetchHrvStatus(): Returns "Balanced", "Unbalanced", or "Unknown"
- fetchBodyBattery(): Returns current BB and yesterday's low value
- fetchIntensityMinutes(): Returns 7-day rolling sum of activity
All functions gracefully handle API failures with safe defaults.
Test count expanded from 14 to 33 covering all scenarios.

- Component rendering (DecisionCard, DataPanel, NutritionPanel)
- Override toggle functionality (POST/DELETE API calls)
- Error handling and loading states
- Cycle information display
Also fixed TypeScript error in login page tests (resolveAuth
initialization).

- Form validation (prevents empty submissions)
- Redirect to dashboard on successful login
Test infrastructure improvements:
- Add @testing-library/jest-dom for DOM matchers

Add override management API for the training decision system:
- POST /api/overrides adds an override (flare, stress, sleep, pms)
- DELETE /api/overrides removes an override
- Both endpoints use withAuth middleware
- Validation for override types, idempotent operations
- 14 tests covering auth, validation, and persistence
Also fix type error in today/route.ts where DailyLog body battery
fields could be null but biometrics object expected numbers.

Add the core daily snapshot API that powers the dashboard. Returns:
- Training decision (status, reason, icon) using decision engine
- Cycle data (cycleDay, phase, phaseConfig, daysUntilNextPhase)
- Biometrics (hrvStatus, bodyBattery, weekIntensity, phaseLimit)
- Nutrition guidance (seeds, carbRange, ketoGuidance)
When no DailyLog exists (Garmin not synced), returns sensible defaults:
hrvStatus="Unknown", bodyBattery=100, weekIntensity=0. This allows
the app to function without Garmin integration.
22 tests covering auth, validation, all decision paths, override
handling, phase-specific logic, and nutrition guidance.

Add authentication infrastructure for protected routes:
- withAuth() wrapper for API route handlers (src/lib/auth-middleware.ts)
- Next.js middleware for page protection (src/middleware.ts)
withAuth() loads auth from cookies, validates session, and passes
user context to handlers. Returns 401 for unauthenticated requests.
Page middleware redirects unauthenticated users to /login, while
allowing public routes (/login), API routes (handled separately),
and static assets through.
Tests: 18 new tests (6 for withAuth, 12 for page middleware)
Total test count: 60 tests passing

Add authentication utilities to pocketbase.ts for server-side auth:
- createPocketBaseClient() - factory for fresh instances per request
- isAuthenticated(pb) - checks authStore validity
- getCurrentUser(pb) - returns typed User from authStore
- loadAuthFromCookies(pb, cookies) - loads auth from Next.js cookies
Includes 9 unit tests covering all auth state scenarios and cookie loading.
This unblocks P0.2 (auth middleware) and all downstream API/page work.
