Summary

Correct eight IFC-Bench v2 reference answers whose previous values were unsupported by the referenced IFC models.

This PR intentionally changes only the ground_truth field for Q6, Q25, Q31, Q130, Q556, Q760, Q764, and Q800. It is independent of the Molio source/oracle corrections in #4 and the four reference-definition corrections in #6.

Evidence

• Q6: reports the sum of stored GSA Space Areas.GSA BIM Area values and states that no building-level GFA is stored.
• Q25: removes an unsupported paint-area total and makes the both-face estimate conditional on an explicit assumption.
• Q31: limits the concrete-wall volume to four explicitly identified foundation concrete walls.
• Q130: removes an unsupported UFA/GFA estimate from a structural model with no spaces or stored area totals.
• Q556: uses the IFC's exact project, building, site, occupancy, and coordinate fields.
• Q760: reflects all 880 walls storing Pset_WallCommon.LoadBearing = false.
• Q764: reflects the single defined building storey instead of inferred floor heights.
• Q800: identifies the eight level-7 unit placeholders and their non-authoritative 1.0 sq m area values.

Validation

• CSV parses to 1,026 rows.
• Row IDs, questions, projects, models, categories, and splits are unchanged.
• The changed ID set is exactly 6, 25, 31, 130, 556, 760, 764, 800.
• The only changed column is ground_truth.
