ADR 0136: a step gates its module, not the machine

ADR 0135 made a step something the mesh derives for any module that prepares its state, which turned ADR 0052's reach into a fault: a module whose database is briefly unreachable would stop every module declared after it on that machine — the fault issue 011 already removed for every other shape, and the reason the catalogue migrates itself at start rather than in a step. A step now stops the rest of its own module and nothing else; an action still gates the machine, because genesis is a row of them and they belong to no module. What was not attempted is reported as skipped rather than left to be inferred from silence.
