Function: blocksCapacity()

  | "held"
  | "pending"

Defined in: server/bookings/capacity.ts:51

The §6.6 is_blocking truth table: a schedule/seat row blocks capacity iff its booking is in an occupancy-holding state. Maintained in the SAME transaction as every status transition.

• held additionally requires a live hold — that part is the QUERY-side hold-expiry predicate above, not this flag (an expired-but-unswept hold keeps is_blocking = true until the sweeper flips it).
• draft / waitlisted never block (a blocking draft would leak a slot forever — nothing TTL-sweeps it).
• terminals completed / no_show still block: the slot WAS consumed.
