After the controller stopped granting a mesh seat to claimants that do not hold it, an image built
before the runtime followed its membership still subscribed the seat's subject, and the refusal
ended the process: ace's postgres runtime crash-looped. A subject the grants leave out now costs
that subject only, as an announcement's already did (issue 217).
The raw subscription that answers discovery ran its loop unguarded, so a refusal escaped as an
unhandled rejection and ended the process: every per-module container crash-looped on 2026-10-03
over a subscription that only serves the mesh seeing the runtime. It is now caught, logged, and the
runtime serves on. Tested against a bus whose permissions refuse the subject; fails without it.
