    "2026-03 — CHQ-P-2026-012: Six independent vendor relationships establish that attestation describes a historical claim rather than current operational state. The assumption is directly under pressure at CONFIRMED evidence state.",
    "2026-07-24 — July 2026 enterprise application attestation reversals: One assessed platform was exploited with ransomware attribution, reversing the prior assessment; one platform was exploited before any vendor flag was raised. Counter-instance: one prompt, accurate advisory recorded in the same window. The dominant pattern (attestation reversed by confirmed exploitation) holds; the counter-instance is evidence the assumption is not universally false while the pattern of reversals without prior attestation signal documents the class-level failure mode."
