#12 — VaR_breach_rate_99_oos_regime_cond metric: - internal/eval/var.go: VaRBreachRate() + kupiecPOF() + LinearProbePredict() (stdlib math only) - internal/eval/var_test.go: 8 golden tests (zero/all breach, perfect calibration, boundary) - cmd/eval/main.go: -metric var flag (no-leakage probe → VaR → Kupiec P) - scripts/var_breach.py: Python equivalent with METRIC_KEY constant (13 TDD tests) - train.py LOCKED VaR EVAL BLOCK: writes VaR_breach_rate_99_oos_regime_cond + kupiec_p to metrics.json - Fixed bug: train.py used bare 'os' before import; now uses module-level '_os' consistently #13 — HMM regime detector + JEPA conditioning seam: - scripts/prepare_regime.py: GaussianHMM (diag, 3-state) on realized_vol; states sorted by mean vol (0=calm, 1=stressed, 2=crisis); deterministic (random_state=42); outputs eurusd_regime.parquet - tests/test_regime.py: 11 TDD tests (dtype, states, determinism, vol sort, daily fallback) - train.py: JEPA_ENABLE_REGIME toggle + REGIME CONDITIONING SEAM (concat baseline, agent-editable) - requirements.txt: hmmlearn>=0.3, scikit-learn>=1.4 78 Python + all Go tests green.
