List a combine group's staff-drawn adjacency edges
/api/link-adjacenciesEvery book_table_link_adjacencies edge for one book_table_link_groups id (2026-09-11): which of the group's own tables actually sit next to each other, drawn on the floor-plan canvas' connect tool. Combining that group's members now requires a connected chain of these edges (see reservation-slots.ts's own comment); an empty list means every member is bookable only on its own or with a single-table fit.
Authorization
sessionCookie The dashboard's Supabase Auth session cookie, set at sign-in. Large sessions are split across
numbered chunks (…auth-token.0, .1), so treat this as a cookie family rather than one name.
Every request re-validates it against the Auth server (getUser()), never by decoding the cookie
locally: a JWT nothing has checked is not a credential. Tenancy is then read from the verified
app_metadata.company_id claim and enforced by row-level security; it is never read from request
input, on any route, ever.
role (admin / staff) is deliberately not in RLS. It gates specific actions in route code,
the operations marked admin below, so hiding a button in the UI is cosmetic only, and a route's
own check is the enforcement.

Never 409s, for the same reason deleting a level does not: `book_tables.link_group_id` is ON DELETE SET NULL (migration 0035), so this un-links its tables and deletes nothing else. Past bookings are unaffected; a reservation holds TABLES (`book_reservation_tables`), never the group they were combined through.
Draw an adjacency edge between two tables POST
Both tables must already belong to the SAME book_table_link_groups row (an ordinary combine group, never a furniture-set piece, which has its own separate combo mechanism); validated server-side, not just by the parser. No Venue Pro gate: an edge only refines an already-created group's own combining behaviour, it cannot create a new combinable group. Idempotent on a duplicate (`alreadyExists: true`), since the canvas' click-to-connect toggle already checks its own edge list before calling this: a repeat only fires on a genuine race between two staff drawing the same line at once.
