Review round 1. The sizing amendment's worst case is one socket client with
all four subscriptions (15 snapshots, about 1.8 MB, 472,061 bytes measured
because fan-out shares artifacts), not seven stuck subscribers. The lifecycle
amendment gains deploy-time validation, the flyedge cpuset and the absolute
bus dir; a known-limits list records what review round 1 left as notes: feed
counters off the container, store quota per router, rollback while in bus
mode, and the old fixtures.
