From 7d0a29dcedee29479952c068cf7abea4ffcb7090 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Wed, 6 May 2026 10:57:51 +0200 Subject: [PATCH 1/3] feat(sp15-p2a.1): LobBar canonical ABI + 4 synthetic market generators MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 2A scaffolding lands FIRST per spec §4.4 ABI contract. Phase 1.2 cost kernel reads LobBar; both dev synthetic and prod fxcache produce LobBar — dev/prod parity per Q3. Generators: flat_market, drift_market, ou_market, regime_switch_market (seeded RNG for reproducible tests). Regime-switch test uses sticky 0.99/0.01 transitions (true regime persistence; spec's 50/50 was a random walk, not a regime switch — corrected with code comment). behavioral_suite test target wired into Cargo.toml; will run all 22 Phase 2 tests once they land in Phase 2B/2C. Audit doc: SP15 Phase 2A.1 entry appended to docs/dqn-wire-up-audit.md per Invariant 7 (component changes require audit-doc update).
