Keep a recorded module at the build its machine runs on every send but a person's push, and say what a send recreates (hq issue 294, ADR 0242)

A plan's gated send for mail carried postgres's and mongodb's new builds
(policy record) to the control node and the anchor on 2026-10-07: a send
composes the machine's whole declaration from the builds the mesh holds,
and the gate only ever looked at modules that roll out. Every send but a
person's push now composes a recorded module from the manifest of the build
the machine was last sent and records that it still carries it; the bus
step moves the bus alone. And each move a gated send carries says how many
of the module's containers it recreates, and whether with a new image or
only their declaration.
