mesh-vault: a watch of the assignments begun again keeps nothing an earlier attempt took, and a module the mirror lacks is read directly before a credential is refused (issue 1126, review round 1)
A watch that failed partway kept what it had taken; begun again, the runtime does not hand a key deleted meanwhile, so
a removed assignment read as standing and credentialRefusal could hand a consumer credential to a node no longer
running its module. Each attempt now begins from nothing held, and a late delivery to an older attempt changes nothing.
A 'not on the node' refusal is confirmed by a direct read first, since a watched mirror can be behind.
