How To Read This Risk Matrix
These tallies reflect the 117 checkpoints evaluated across the 9 analytical layers. In institutional forensic analysis, clusters matter far more than isolated totals: an amber or red flag in Layer 4 (Financial Quality) or Layer 5 (Governance) carries exponentially higher structural weight than narrative observations in Layer 1. Always evaluate flags against company peers and industry context.
