W45 §3.5 Step 1g: integrate derivation-drift falsifier into gate_phoenix.sh

SonicField · SonicField · commit eb3cdf3f549f · 2026-04-23T17:23:58.000-07:00
Adds Step 1g per spec §2.7.3 python#3, invoking scripts/w45_section_3_5_derivation_drift.sh --strict after Step 1e (W44 DO-NOT-USE caller gate). Step 1f reserved for future W45 §1-§2 bridge-sig falsifier integration. Pattern mirrors Step 1e (W44): capture output, exit code, GATE_PASS flag, FAILURES annotation. ~15L diff. Authorization: supervisor 00:22:51Z post-push priority (1) per spec §2.7.3 python#3 integration step; ~10L estimate (actual 15L for output capture + failure annotation parity with Step 1e).
