T6B.2 evidence

Disposable overlay and Core-clone matrices for the T6B.2 engineering tranche.

Canonical rebound files (post combined-topology MRO fix):

• T6B2-runtime-matrix-20260817T102934Z.json
• T6B2-W10-regression-20260817T102934Z.json
• T6B2-W03-regression-20260817T102934Z.json
• T6B2-E1.2-20260817T103735Z-security-matrix.json
• T6B2-W01-core-20260817T102934Z.json
• T6B2-W02-core-20260817T103540Z.json
• T6B2-W05-core-20260817T103857Z.json

Earlier overlay matrices (*T100457Z*) are superseded. T6B2-W01-polluted-overlay-discarded-* is not certification.

Independent T6B.1 auditor files live under ../audit/ and ../T6B-evidence/ and must not be staged here.
