From 0d373da490256dab96abbe7540e5050fd9a2bfc0 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Sun, 26 Apr 2026 12:33:28 +0200 Subject: [PATCH] plan5(task4): tiered-exit validation script suite (tier1/2/3 checks) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Creates scripts/validation/ with per-tier exit checks consuming the aggregate JSON from scripts/aggregate-multi-seed-metrics.py (P5T1B): check_tier1.py — convergence (std/mean ≤ 0.15 on val_sharpe / avg_q_value / train_loss; avg_q_value max ≤ 500 fold-1 explosion guard; placeholders for Q-saturation + hot-path-DtoH per spec). check_tier2.py — behavioural (val_trades_per_bar ≥ 0.005, val_active_frac > 0.2, dir argmax entropy > 0.8·log4 with val_dir_entropy primary + val_dir_dist_* fallback). check_tier3.py — profitability (val_sharpe_annualised > 1.0 with val_sharpe per-bar fallback, val_win_rate ≥ 0.52 gated on >500 trades, val_profit_factor mean ≥ 1.1 AND cross-seed std < 0.3). check_all_tiers.py — subprocess wrapper, exits 0 only if all pass. Stdlib-only (statistics / argparse / json / subprocess) — no new deps. Defensive missing-metric handling: each check FAILs with an explanatory message when its required aggregate key is absent rather than silently passing, so missing HEALTH_DIAG metrics are surfaced loudly. Test harness scripts/validation/tests/test_tier_checks.sh exercises good + bad fixtures across all four scripts and against the wrapper. Audit row added to docs/dqn-wire-up-audit.md documenting the suite + the deferred metrics list (val_trades_per_bar, val_active_frac, val_dir_entropy/_dist_*, val_sharpe_annualised, val_win_rate, val_profit_factor, val_trade_count) that HEALTH_DIAG must emit before tiers 2/3 can ever PASS on real data — tracked for Plan 5 Task 5 pre-flight wire-up.
