Phase 5 is complete. All 53 tasks are done, verified on a fresh database in a single clean run: **121 unit tests**, **55 integration tests**, and **15 E2E journeys** (6 Phase 4 + 9 new Phase 5) all passing, plus a clean `tsc`/`eslint`/`build`.
Summary of this final stretch:
- **Fixed a real bug**: `StaffService`'s break/time-off update/delete functions threw uncaught instead of failing gracefully on a permission mismatch — fixed with proper `PERMISSION_DENIED` handling, covered by new integration tests.
- **Built the remaining Phase 5 UI**: Breaks editor, Time Off editor, Barber Profile, and Notification Preferences — all wired to real services, no placeholders.
- **Extended seed data**: more customers, loyalty accounts/transactions/rewards, and appointments spanning every status today (anchored to real time so the "Current Appointment" priority logic is reliably exercised).
- **Found and fixed a second real bug live in the browser**: the Break/Time-Off edit sheets showed stale default values instead of the item being edited (a classic `useState`-doesn't-reinitialize-on-prop-change bug) — fixed with a `key` prop to force remount.
- **Wrote the full Phase 5 test suite**: unit tests for `selectCurrentAppointment` and all `StaffService` validators, integration tests for `LoyaltyService` and `StaffService` (including the permission-fix regression tests), and 9 new Playwright E2E journeys covering the brief's exact required list.
- **Did the desktop-responsive pass**: a persistent sidebar nav replacing the bottom bar at `lg:`, a genuine calendar+"Right Now" side-by-side split, and 2-column layouts for the clients list and customer details — addressing the brief's explicit "more than simple centering" requirement.
- **Wrote [docs/phase-5-summary.md](docs/phase-5-summary.md)** documenting everything above in full.
Nothing is committed — the whole session (Phases 2–5) sits uncommitted on top of the initial template commit, same as you left it. Let me know if you'd like me to commit, or if you want to move on to Phase 6.
Seed data extended with a second barber (different hours/services), a beard-trim service + category, breaks, time off, a guest customer, and appointments in all three key states — verified against a live throwaway Postgres.
14 new integration tests (38 total with Phase 3's) covering guest/authenticated booking, any-barber assignment, slot-conflict handling, ownership enforcement, guest-data isolation, and book-again repricing.
Playwright E2E suite for the 6 required customer journeys, with its own global-setup.ts that migrates and seeds a database automatically.
Full verification pass, which caught and fixed three real bugs along the way (not just test-workarounds):
A date off-by-one bug in the calendar picker that made real weekdays show as closed for anyone in a UTC+ timezone (including the business's own).
A dialog that could vanish mid-confirmation on cancellation, before the customer could read the late-cancellation notice.
A silent test-cleanup leak in the Phase 3 fixtures that had been leaking stray businesses since Phase 3.
Plus a baseline desktop-responsive fix (centered max-w-2xl columns) across Home/Appointments/Settings/booking flow, since desktop had been effectively unstyled.
Final state: 90 unit tests, 38 integration tests, and all 6 E2E journeys passing together on a fresh database; clean tsc, eslint, and next build. Full writeup with routes, security model, guest-matching rules, known limitations, and what to check before Phase 5 is in docs/phase-4-summary.md.
Base app architecture:
Route groups for customer, staff and owner.
* Reusable design system with around 20 UI components.
* Complete Prisma schema.
* Authentication with email/password and Google.
* Role and permission model.
* Protected routes.
* Clean separation between features, services, components and shared utilities.
