Read memberships from the grants part's state, what the mesh holds from the indexer and placement, and give bundles newest, since and watch on logs, so the tool runner asks the controller for nothing it keeps (issue 1955, ADR 0571 clauses 1, 4, 5, 7)

Pins mesh-sdk bb993dd. The assignments stream stays the membership's
fallback until the lease write; a log another module keeps is read as
<module>.<log>.
