jschoubben d543ff7126 Judge each read for its reader with mesh-sdk's ReadsAnnouncedBy, so the parts named for the lease are granted it, and say a refusal once (issue 774)
2536 reads of mesh-controller.lease were refused on 2026-10-30 (mesh-vault, mesh-grants, the assigner,
artifact-store-tools, the watchman, mesh-config). The controller composed the bus's users with its own
copy of a reader-less judgement (internal/broker ReadsAnnounced), which knows no named readers: the lease
is announced readable by nobody and read by the parts named for it (ADR 0547 clause 9, ADR 0561 §3). The
copy is deleted; BusRecords judges each read for its module with buscompose.ReadsAnnouncedBy. Each
refusal was also printed on every composition, about 420 times a read; it is now said once per process.

mesh-config's read of the lease stays refused: it reads the lease for its take-over (hand-back ends at
the lease write, ADR 0561 §3) and is not among the named readers. That is mesh-sdk's NamedReaders,
routed to the lead.

Quick fix: mark the lease readable in the controller's announcement (tried and reverted: it would open
the lease to every module and contradict ADR 0561 §3). Thorough fix: one judgement, the SDK's, for every
composer. Chose thorough.

Research 072 piece: 03-domains, mesh-grants (bus membership and grants leave the controller): the
controller composes reads with the same SDK function the grants part uses.
