First-party booking system on top of Stalwart calendars (no third-party scheduling dependency). Hosts expose public booking pages; visitors pick a slot computed from the host's live Stalwart free/busy, and confirming writes the event to the host's calendar and sends a dezky-branded confirmation with an .ics. platform-api (services/platform-api/src/scheduling): - Schemas: Host, StalwartCredential (AES-256-GCM at rest), AvailabilitySchedule, EventType, Booking, SlotLock (unique (hostId,startUtc) + TTL). - StalwartCalendarModule: JMAP gateway (free/busy via Principal/getAvailability, event create/delete, scheduleAgent=client) + on-behalf app-password provisioning. CredentialCipher for at-rest encryption. - DST-correct slot engine (Luxon) with unit tests; two-layer double-booking guard (atomic SlotLock + live free/busy re-check). - Booking confirm/cancel/reschedule, branded email + .ics via JMAP submission, self-service manage tokens. /api/v1 public + tenant-gated admin routes, per-IP rate limiting. apps/booking: standalone public, whitelabel booking app (booking.dezky.eu) — path-based tenant resolution, per-tenant brand colour, booking + manage flows. apps/portal: admin scheduling page (hosts, event types, availability, bookings with edit/delete + admin cancel/reschedule) and proxy routes. infra: booking dev service in docker-compose; scheduling env vars.
