-- The seats are data the control plane owns, not a slice compiled into it (novox/hq ADR 0122).
--
-- Until this, the closed set 0110 defines lived only as a Go slice, referenced by name everywhere,
-- so renaming a seat or adding one meant a controller rebuild and a mesh-wide, freeze-prone deploy.
-- The set is now a table: one row per seat, seeded from the binary's defaults the first time the
-- control plane comes up, and thereafter the live copy the control plane reads and an operator can
-- change. A rename becomes an update here rather than a release.
--
-- The name is the key for now, because claims and held records still reference a seat by name; the
-- move to a stable id that a rename does not touch is the next step (ADR 0122). `delivers` is empty
-- for a seat that answers for no provision, matching the compiled default.
