Two things were treated as one. The mesh's own artifact store holds the store seat and is internal by
design — reached by name over the overlay, no accounts, ADR 0082. Serving a registry publicly is a
service the mesh can host: a module with its own name, accounts and storage, like anything else it
runs for somebody. The conversion this report was written beside gave the seat holder a second public
door over the same filesystem, which is neither.
Keeps the original issue whole — no garbage collection, and the settings a routine needs are not
enabled — drops the two-door complication, and sharpens one thing: deletion on the only door is
deletion on a door with no accounts, which the predecessor kept behind its authenticated one.
