From 79f4d8b2411964e599749b68ec2c85dec9756e42 Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Sun, 12 Jul 2026 09:47:03 -0400 Subject: [PATCH] W1 forensics 1: the five transport mechanisms (registration 4951218279) Diagnostic (reported_not_gated), one run, publishes regardless. Measures the five initialization/support/scope mechanisms candidate 1 isolated (grading 4951216895) before candidate 2 designs. Instrumentation bit-identity vs the committed transport_deployment_v1 machinery is EXACT (0.0) for every re-simulation; the additive decompositions telescope at machine epsilon. - Q1 marital: extending exposure barely helps (mean |b|~0.028); the hazard-level residual dominates (mean |c|~0.095, 9/10 cells). Observed-init == rate_a (the frame's A_MARITL) is the prohibited regenerated_surface identity; initialization (entry-state seeding) is the necessary lever. - Q2 boundary: nearest-bin clears 0/6, the train-fitted boundary extension clears 4/6 (62-69 + the 18-24 profile); 18-24 participation resists (PSID heads/spouses over-state it vs the CPS all-person frame). - Q3 scope: scope + composition telescope; scope is NOT the whole miss -- a large composition residual (size-1 lone-adult over-generation) remains. - Q4 DI: concept delta (duration-accumulated stock vs work-disability point-prevalence) dominates (>0.5 share; 60-FRA +21.3pp duration vs +2.6pp M4 shape); insured denominator not even archived. GATE-DESIGN finding. - Q5 tail: the corrected (p0-inclusive, lighter) tail moves PPI savings DOWN (0.0169 -> 0.0137), widening the gap to NRA (0.202); C1 non-reversal is ROBUST in the conservative direction. C2's elimination<->+2pp swap holds under both tails. Artifact runs/gate_w1_forensics1_v1.json via write_new(..., sidecar=True) -- the first artifact to adopt the #152 env sidecar (.env.json). Tests: 17 always-runnable + 5 PSID reproduction pins; tier manifest refreshed (artifact +17, integration_psid +5).
