This consolidates #4 and #6 on top of the current main, so the reviewed fixes can be merged without asking you to resolve the overlapping CSV checksum conflicts.

It includes:

• the authoritative 73,945,142-byte Molio IFC source (sha256:626654e3…)
• the 33 audited Molio ground_truth corrections, including the reviewed Q608 count of 3,586 non-proxy IfcBuildingElement entities
• the four reference-definition corrections from #6
• the clarified Q161 facade basis: 4,565.49 m² of stored wall quantities plus an explicit 18.0 m² curtain-wall elevation-bounding-box estimate
• one final README checksum for the combined CSV

Validation:

• 1,026 rows with 1,026 unique stable IDs
• frozen split unchanged at 514 test / 512 train
• exactly 37 ground_truth cells differ from current main; no question text, IDs, projects, categories, or split assignments changed
• restored Molio file has no NUL bytes, has a complete ISO-10303-21 envelope, and matches the reviewed buildingSMART object hash
