Get raw attendees for a set of event IDs. Used by the calendar to load attendees for standard events whose decrypted date matches the selected calendar date.

Look up attendees by plaintext tokens, returning full booking data. Two queries: attendees by token index, then all event_attendees for those attendees. Returns results in the same order as input tokens (deduped). Bookings sorted by start_at then event_id for deterministic ordering.

Get attendees for an event without decrypting PII Used for tests and operations that don't need decrypted data

Get distinct attendee dates for daily events. Used for the calendar date picker (lightweight, no attendee data).

Get event and its activity log in a single database round-trip. Uses batch API to reduce latency for remote databases.

Get event and a single attendee in a single database round-trip. Used for attendee management pages where we need both the event context and the specific attendee data.

Get event and all attendees in a single database round-trip. Uses batch API to execute both queries together, reducing latency for remote databases like Turso from 2 RTTs to 1. Computes attendee_count from the attendees array.

Get event with attendee count (from cache)

Get event with attendee count by slug (from cache)

Get a single group by slug_index (from cache)

Per-event view of group remaining capacity. Daily events are dropped when date is null — their cap is per-date, so a cumulative count would misreport spots that other dates still have.

Per-group remaining capacity. Groups with max_attendees <= 0 (no cap) are omitted from the map. With date = null, daily-event attendees count cumulatively — correct for booking-time enforcement after upstream date validation, misleading for display.

Returns undefined when no group cap applies: ungrouped, uncapped group, or daily event without a date.

Get the newest attendees across all events without decrypting PII. Used for the admin dashboard to show recent registrations.

Remove a single event link for an attendee. If the attendee has no remaining event links, deletes the attendee entirely. Returns whether the attendee was fully deleted.

Update an attendee's PII (name, email, phone, etc.) — shared across all event links. Caller must be authenticated admin (public key always exists after setup).

Update an attendee's checked_in status for a specific event. Caller must be authenticated admin (public key always exists after setup)

Update a single event link's quantity and date with atomic capacity check. Excludes this attendee's current row from the capacity calculation.

Validate that an event type is compatible with a group's existing events. Returns an error message if mismatched, null if OK. Pass excludeEventId to skip a specific event (for edit-self case).

Verify a user's password (decrypt stored hash, then verify) Returns the decrypted password hash if valid (needed for KEK derivation)

Wrap a table so that insert, update, and deleteById automatically call an invalidation callback (e.g. cache invalidation). Eliminates the repeated spread-and-override pattern in groups/holidays/events.
