# Phase 02 Plan 01: Foundation — Schema Columns, Test Harness, Dev-Auth Bypass Summary

Horizontal foundation for Phase 2 calendar slice: two schema columns pushed to live MariaDB, PWA jsdom test runner operational, dev-auth bypass middleware with production hard guard, three ICS fixtures, and four RED test stubs with concrete behavioral contracts.

## What Was Built

### Schema Changes (Task 1)

Added to `apps/api/src/db/schema.ts`:
- `calendarEvents.hasRrule`: `boolean('has_rrule').default(false).notNull()` — pre-filter flag for recurring event masters (RESEARCH.md §Pitfall 5)
- `calendarEvents`: new index `idx_calendar_events_has_rrule` matching style of `idx_calendar_events_dtstart_utc`
- `calendars.isShared`: `boolean('is_shared').default(false).notNull()` — operator-marked shared-family calendar flag

Both columns pushed to live MariaDB (503-event cache intact). `SHOW COLUMNS` confirms presence.

### PWA Test Harness (Task 1)

- Created `apps/pwa/vitest.config.ts` with `environment: 'jsdom'` and `globals: true`
- Added `"test": "vitest run"` to `apps/pwa/package.json` scripts
- Added devDependencies: `vitest@^4.1.8`, `@testing-library/react@^16.3.0`, `@testing-library/jest-dom@^6.6.3`, `jsdom@^26.1.0`
- `pnpm install` completed without errors

### ICS Fixtures (Task 1)

Three fixtures created at `apps/api/tests/fixtures/`:
- `weekly-dst.ics`: weekly VEVENT at `DTSTART;TZID=America/New_York:20260301T100000` with full VTIMEZONE block (STANDARD + DAYLIGHT subcomponents for March 2026 EST→EDT transition)
- `allday-birthday.ics`: `DTSTART;VALUE=DATE:20260615` with `RRULE:FREQ=YEARLY`, no DTEND — pure DATE type
- `exdate-series.ics`: `RRULE:FREQ=WEEKLY;COUNT=5` with `EXDATE;TZID=America/New_York:20260615T090000` — exactly one occurrence excluded

All three fixtures parse via `ICAL.parse()` without throwing.

### RED Test Stubs (Task 1)

Four test stubs with concrete behavioral contracts (not bare failing imports):

**expand.test.ts**: Three behavioral contracts —
1. DST wall-clock: every occurrence in March 2026 window has `T10:00:00` in the ISO start string, regardless of EST/EDT offset. Tests both pre-transition (2026-03-01) and post-transition (2026-03-15) occurrences.
2. All-day: `allDay:true` and `start === '2026-06-15'` (no `T` component)
3. EXDATE: length === 4 (not 5), June 15 occurrence absent

**events.test.ts**: Four contracts — 400 on missing start, 400 on missing end, 400 on malformed date, 200 + `{occurrences: []}` with color/isShared fields on valid window.

**hydrateEvents.test.ts**: Four contracts — all-day → `Temporal.PlainDate`, timed → `Temporal.ZonedDateTime`, shared `isShared:true` → calendarId `'shared'`, personal `isShared:false ownerUserId:7 calendarId:99` → calendarId `'7'` (NOT `'99'`).

**calendarConfig.test.ts**: Four contracts — `WEEK_START_DAY === 0`, `firstDayOfWeek === 7` (Temporal 0→7 translation), `'shared'` calendar in config, per-member by `String(userId)`.

All RED stubs fail at import resolution (module not built yet) — correct RED state.

### Dev-Auth Bypass (Task 2)

Created `apps/api/src/auth/devBypass.ts`:
- Exports `devAuthBypass(): MiddlewareHandler`
- First conditional is `NODE_ENV === 'production'` — hard guard (T-02-01 mitigation)
- Returns no-op passthrough when production OR bypass flag unset
- When active: `c.set('user', DEV_USER)` then `await next()`
- Exports `DEV_USER = { id: 1, oidcIss: 'dev', oidcSub: 'dev-user', displayName: 'Dev User', color: COLOR_PALETTE[0] }`

Mounted in `apps/api/src/index.ts` on the line immediately before `oidcAuthMiddleware()`.

All three devBypass.test.ts cases pass: production guard, unset-flag passthrough, active injection.

`.env.example` and `docs/deployment.md` updated with bypass documentation and production prohibition.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocker] drizzle-kit push replaced with direct ALTER TABLE**
- **Found during:** Task 3
- **Issue:** `drizzle-kit push` emitted a non-TTY interactive prompt. The "data-loss" warnings were false positives — MariaDB stores int as `int(11)` display width but drizzle-kit 0.31.x sees this as a type change on existing rows. The prompt cannot be auto-confirmed without TTY.
- **Fix:** Applied the two actual new columns directly via `ALTER TABLE calendar_events ADD COLUMN IF NOT EXISTS has_rrule tinyint(1) NOT NULL DEFAULT 0` and `ALTER TABLE calendars ADD COLUMN IF NOT EXISTS is_shared tinyint(1) NOT NULL DEFAULT 0`, plus the index. Outcome is identical to what drizzle-kit push would have done for the new columns.
- **Data integrity:** 503 events confirmed intact post-migration. SHOW COLUMNS confirms both columns and the index exist.
- **Note for future plans:** The int(11) vs int type drift is a display-width-only issue in MariaDB. It does not affect runtime behavior. If drizzle-kit push is run again, it may continue to prompt about these. Consider adding `drizzle.config.ts` overrides or accepting the prompt in an attended session.
- **Files modified:** live MariaDB schema (no source file change)

## Known Stubs

The following test stubs are intentionally RED (modules not yet built):
- `apps/api/tests/broker/expand.test.ts` — awaits `apps/api/src/broker/expand.ts` (Plan 02)
- `apps/api/tests/routes/events.test.ts` — awaits evolved `apps/api/src/routes/events.ts` (Plan 02)
- `apps/pwa/src/lib/hydrateEvents.test.ts` — awaits `apps/pwa/src/lib/hydrateEvents.ts` (Plan 03)
- `apps/pwa/src/lib/calendarConfig.test.ts` — awaits `apps/pwa/src/lib/calendarConfig.ts` (Plan 03)

These are tracked RED stubs, not incomplete work. Each encodes a concrete behavioral contract for the implementing plan.

## Threat Flags

No new threat surface introduced beyond what is already in the plan's threat model. The `devAuthBypass` middleware is guarded by both `NODE_ENV === 'production'` and documented in `.env.example` and `docs/deployment.md`.
