Blocker 6: enrolment-expired carries the enrolment-issued event's message id (IssuedID), since a bundle's publish
answers no stream sequence and ADR 0587 §2 asks only that the event be named; it gains a codec refusing no event named.
Blocker 7: NodeHealth gains Fallback (node, the login fallen back from, why, at), from which the watchman raises
node-account-fallback (ADR 0583 §6); a fall back naming another node is refused. A token missing its signer now says
the vault's signing key, not the retired word. Tested as rows of TestNodeRecord and the control records test; no new
test function (1438 unit tests).

The engine composes its node's wants itself, so the derivation the controller keeps
privately moves beside the layout: DeclaredPackagesOf gives the mirror's bytes from the
compositions, DiffDeclaredPackages what the node seat's verb packages compares until the
lease write, and EnginePackagesRead names the state as readers declare it (mesh-host.packages,
as mesh-host.data). Each engine may read the controller mirror's key of its own node alone.

The node key <node>.node is a write's commit: it names each placed module with its value's digest, the
module keys carry the value they replace until it lands, so a reader never composes half a write. Every
reader goes through PlacementKeys/PlacementsOf, which read the legacy placement.<node> too while the
change is delivered.
NodeHealth.Root: each such account's verdict (healthy, unhealthy with its way to root, unknown while the setuid search
runs), the module and resource declaring it. NodeHealth.Contract: the engine's statement contract, so a reader tells an
engine older than the judging. Test: a row in TestTheControlRecordsReadTheirWritersValues, read back byte-equal.
NetworkPart.Targets: the hub's machine for "hub", the machine whose tunnel address is each resolver's; empty where the
part is the machine's own. Filled by the node-engine from its tunnel's peers. Test: a row in
TestTheControlRecordsReadTheirWritersValues, read back byte-equal.
