The lead's ruling of 13:0x replaces 12:5x's said-subject: mesh-broker's events follow every seat, on
mesh.seat.mesh-broker.event.<event> in the shared events stream, 7 days; the bus module keeps a longer history on a
stream of its own module. So every seat family is that stream filtered to the seat's subjects: a definition says 7
days and no cap of its own, and the reader refuses anything else.

ADR 0625 §1-§3 (accepted 12:45): the seat set stays the root Go module's package; each seat defined whole is a Go
module of its own, since the fingerprint counts a Go module's go.mod and go.sum, so a change of one seat moves only
its importers. A seat's module imports nothing: the registry part's types are written into each registry seat whole,
so no seat module requires a sibling's version.

go/seats the seat list every reader compiles and every seat's name; a package per whole seat with its names, subjects,
types and a test of its fixtures; ts/ the same as a TypeScript package. Written by seatgen, never by hand.
