The builder's `build.ended` stream declares last-per-subject; the grants part composes it one message per subject and its readers read
whole; the assigner reads it whole at its start then follows it (consumes `build.ended.**`), so what was built and a failed build's error
survive its restart. world.built, buildNeeds, manifestOf and the put verbs read the ends; the manifest reads no builder bucket;
assigner_put's fingerprint-prefix form goes.

A seat definition's events of the seat list, and mesh-sdk's four finding events (views.FindingSubjects), so a `*` emitter before one reaches each declaring module's own stream; any other `*` entry stays the shared stream's.
