Disabling the filter left all twenty-two assertions green, which means nothing
tested it. The counter-case I had written exercises the skip in the derivation,
not the filter inside the registry selection, so the feature went out with no
coverage at all — the project's own favourite failure, in the change that was
meant to remove noise.
Three assertions now cover it: three repositories of which one runs, the
counter-case showing the same call returns all three without estate knowledge,
and one that pins what the rule must not do — it excludes repositories, not old
tags, so a rollback target of a running service still counts.
Same sabotage as before now turns one of them red.
