The indexer whole: two catalogue modules report their imports at their builds' end, mesh-sdk merges a change of buildstep alone, the packages key names the merge with a digest per package, the buildstep importer moves and the other keeps its fingerprint though the version line would have moved it (ADR 0593 §2-§4; D11).
