   "notes": "`counts`, `relations` and `storeys` are the normative SPEC.md §6.1 blocks and are what the gate reads; `semantic_surface` and `excluded` are the declared result, and tools/verdict.py fails with MANIFEST_ERROR if they disagree with what those blocks imply — so an accidental status flip is loud rather than a silent surface change. Tracking issues 33/34/35/204/211/212/218/222 are rvt-rs issues (github.com/DrunkOnJava/rvt-rs). Departing from the upstream rvt-rs manifest exactly as corpus/README.md documents, the `decoder_*` fields are dropped and a category that carries no cross-witness type key is dropped with them. The bridge file is a 20 KB element-export fixture, not a full project schedule, so four of the six agreeing surface fields are zero counts — but Revit writes the complete fifteen-storey spatial hierarchy into it even so, which is why `entity_counts.IFCBUILDINGSTOREY` and `storeys.IFCBUILDINGSTOREY` are `known` here and carry the same fifteen (name, elevation) pairs the full export does. `relations.IFCRELFILLSELEMENT` goes the other way: this fixture carries no IfcRelFillsElement at all, so the relation is excluded first-class and is scored only on the sibling full-project artifact. See PROVENANCE.md."
