Scheduling that rechecks correctness at commit

Slot conflicts are validated at booking mutation time with transaction-safe guarantees and idempotency keys.

Event types, availability, teams, webhooks, calendar sync, and writeback controls are exposed in product UI.

One-on-one booking, team booking, cancel/reschedule links, and embed scripts all route to implemented APIs.

Create one-on-one or team event types, define location mode, and control active state from organizer UI.

Share public booking pages with timezone handling, buffer-aware slot generation, and duplicate-request protection.

Track analytics, run webhook deliveries, sync calendars, and clear writeback failures from authenticated surfaces.

All links below are wired to currently implemented product functionality.

OAuth connect, sync, busy-window conflict blocking, and writeback retries.

Provider parity with connection lifecycle, sync scheduling, and failure visibility.

Booking lifecycle emails with delivery telemetry and action-link support.

Low-cost API runtime with Hyperdrive bridge to Neon.

Start with demos, then move into organizer workflows and analytics without changing infra.
