From cd5aa3402b381877981293c7b2cd6197c2089018 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Fri, 15 May 2026 16:53:16 +0200 Subject: [PATCH] =?UTF-8?q?feat(alpha):=20wire=20Phase=201d.3=20stacker=20?= =?UTF-8?q?into=20smoke=20=E2=80=94=20H=3D600=20VERDICT=20PASS?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase E.1 Task 12b complete. The H=600 DQN smoke now consumes real alpha_logit from the Phase 1d.3 stacker (Mamba2 + 7-input MLP stacker trained for AUC=0.673 on test), and PASSES all four kill criteria: Q_SPREAD_EMA = 10.92 ≥ 0.05 PASS ACTION_ENTROPY_EMA = 1.97 ≥ 1.099 PASS RETURN_VS_RANDOM_EMA = +1.043 ≥ 0.0 PASS ← jumped +3.62σ EARLY_Q_MOVEMENT_EMA = 0.099 ≥ 0.01 PASS Overall: PASS (H=6000 scale-up VIABLE) Before/after comparison (same env, same DQN, only alpha_logit changed): alpha_logit=0 alpha_logit=Phase1d.3 rollout_R_mean (final) -18,272 -18 RETURN_VS_RANDOM_EMA -2.58σ +1.04σ Overall verdict FAIL PASS The 1000× reduction in episode loss + the +3.62σ rvr swing definitively proves the "first-best-action lock-in" hypothesis from the previous FAIL analysis was a SYMPTOM, not the cause. The cause was alpha_logit=0 placeholder starving the policy of directional signal. With real Phase 1d.3 alpha, the linear Q-network learns to use it cleanly — no NoisyNet, no MLP, no architectural change needed. Integration pieces in this commit: 1. Cargo workspace registration: ml-alpha added as a workspace dep, ml's manifest now depends on ml-alpha for FxCacheReader access. (ml-alpha already depends only on ml-core, so no circular risk.) 2. alpha_dqn_h600_smoke.rs: two new CLI args --fxcache-path load snapshots from precomputed fxcache (mid from raw_close, bid/ask synthesized at fixed half-tick, 81-dim features extracted for spread_bps / l1_imbalance / ofi / mid_drift) --alpha-cache load Phase 1d.3 stacker logit cache produced by `alpha_train_stacker --alpha-cache-out`. Each cache entry aligns to the corresponding fxcache bar, populates SnapshotRow.alpha_logit (and derives alpha_confidence = |sigmoid(z)-0.5|). 3. Snapshot source selection: in main(), --fxcache-path takes priority when both paths are set; --alpha-cache requires --fxcache-path (alignment guarantee). Original --mbp10-dir path unchanged for non-cached runs. 4. Two new helper fns: load_alpha_cache (binary [u32 n] + [f32; n] reader), load_snapshots_from_fxcache (FxCacheReader → Vec with synthesized bid/ask and alpha_logit/alpha_confidence from cache). alpha_logits_cache.bin (7.6 MB, 1.97M f32 entries) is .gitignore'd — regenerable from `cargo run -p ml-alpha --release --example alpha_train_stacker -- --fxcache-path --alpha-cache-out config/ml/alpha_logits_cache.bin` (~2 min on RTX 3050 Ti). Reproduction of this PASS verdict: cargo run -p ml --release --example alpha_dqn_h600_smoke -- \ --fxcache-path /home/jgrusewski/Work/foxhunt/test_data/feature-cache/9297....fxcache \ --alpha-cache config/ml/alpha_logits_cache.bin \ --horizon 600 --n-episodes 1000 Total run time ~10s after fxcache load. Verdict + per-checkpoint KC trajectory in config/ml/alpha_dqn_h600_smoke.json. NEXT: Task 13 — scale to H=6000 (the production horizon). Per the plan, PASS at H=600 unlocks H=6000. --- .gitignore | 1 + Cargo.lock | 1 + Cargo.toml | 1 + config/ml/alpha_dqn_h600_smoke.json | 172 ++++++++++---------- crates/ml/Cargo.toml | 1 + crates/ml/examples/alpha_dqn_h600_smoke.rs | 176 ++++++++++++++++++++- 6 files changed, 263 insertions(+), 89 deletions(-) diff --git a/.gitignore b/.gitignore index 22c61a293..d59b018fe 100644 --- a/.gitignore +++ b/.gitignore @@ -194,3 +194,4 @@ crates/ml/ml/ # Foxhunt audit hook dedup state (cleared at SessionStart) .claude/.foxhunt-audit-state +/config/ml/alpha_logits_cache.bin diff --git a/Cargo.lock b/Cargo.lock index fab5f6855..eb6ee110c 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5972,6 +5972,7 @@ dependencies = [ "lru", "memmap2", "mimalloc", + "ml-alpha", "ml-asset-selection", "ml-backtesting", "ml-checkpoint", diff --git a/Cargo.toml b/Cargo.toml index 053a003cc..674c99f7b 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -440,6 +440,7 @@ ml-ppo = { path = "crates/ml-ppo" } ml-supervised = { path = "crates/ml-supervised" } ml-hyperopt = { path = "crates/ml-hyperopt" } ml-features = { path = "crates/ml-features" } +ml-alpha = { path = "crates/ml-alpha" } ml-labeling = { path = "crates/ml-labeling" } ml-regime = { path = "crates/ml-regime" } ml-regime-detection = { path = "crates/ml-regime-detection" } diff --git a/config/ml/alpha_dqn_h600_smoke.json b/config/ml/alpha_dqn_h600_smoke.json index b59ef061d..5e8f8cfff 100644 --- a/config/ml/alpha_dqn_h600_smoke.json +++ b/config/ml/alpha_dqn_h600_smoke.json @@ -1,8 +1,8 @@ { -
