Two same-seed runs now produce bit-equal eval_summary.json, alpha_rl_train_summary.json,
and diag.jsonl (modulo wall-clock elapsed_s). The 5-phase falsification chain landed:
Phase 2 PER tree-rebuild: __threadfence is NOT a grid-wide barrier; multiple blocks
raced across sum-tree levels. Fix: Grid=(1) Block=(1024) + __syncthreads
in rl_per_tree_rebuild.cu.
Phase 2.3 cuBLAS GEMM_DFALT + TF32 default-math allowed split-K non-deterministic
accumulation at 3 sites. New crates/ml-alpha/src/cublas_determinism.rs
applies CUBLAS_PEDANTIC_MATH via FOXHUNT_DETERMINISTIC env toggle
(0=TF32 prod, 1=PEDANTIC dev default, 2=DEFAULT_MATH control).
Phase 2.6 Two bugs surfaced sequentially in the backward kernel chain:
(1) rl_iqn_tau_cos_features had a multi-block r/w race on prng_state[batch]
— all N_TAU=32 blocks read seed; only tau_idx==0 wrote back; no
inter-block barrier. Fix: split into READ-ONLY rl_iqn_tau_cos_features
+ new sibling rl_iqn_advance_prng_state launched on same stream
(kernel-launch ordering = grid-wide barrier).
(2) OutcomeHead::new called near_zero_xavier without scoped_init_seed,
falling back to time+thread-id RNG. Stayed dormant until first done
event activated non-sentinel labels and divergent weights flowed via
grad_h_t_outcome into encoder gradient. Fix: add seed param + install
scoped_init_seed(dqn_seed.wrapping_add(0x0CE0)) guard.
Validation (./scripts/determinism-check.sh --quick, RTX 3050, b=128, 200+50 steps):
- All 200 rows of checksums.* leaves match (rel-tol 1e-5, abs-tol 1e-7)
- eval_summary.json, alpha_rl_train_summary.json byte-equal between runs
- diag.jsonl byte-equal modulo elapsed_s
- Eval pnl identical run-A vs run-B at seed 42
Pre-fix baseline (Phase 2.5 measurement): same-seed eval pnl spread $450k
($187k vs -$261k). Post-fix: $0 spread.
Speed cost: ~1.5ms/step amortised; ~10-15% slower than TF32 production
(PEDANTIC tax — acceptable in dev, toggle to FOXHUNT_DETERMINISTIC=0 for prod).
Mapped-pinned discipline: all 11 NEW memcpy_dtoh sites in diagnostic dump methods
+ per-step checksum readback use a new pub(crate) helper
read_slice_d_into<T: Copy>(stream, src, dst) — MappedRecordBuffer + raw
memcpy_dtod_async + raw_stream_sync + volatile read. Generic over T (f32, f64,
i32, u32, u8). Satisfies feedback_no_htod_htoh_only_mapped_pinned + hook guard.
Bundled Tier 1.5 fast-dev-cycle infrastructure (spec
docs/superpowers/specs/2026-06-02-fast-dev-cycle.md):

- scripts/determinism-check.sh runs mid-smoke twice, diffs checksums
- scripts/tier1_5_verdict.py behavioral kill verdict
- AdamW checkpoint save/load (crates/ml-alpha/src/trainer/optim.rs)
- IntegratedTrainer checkpoint save/load (resume from checkpoint)
- 15 Phase 1 checksum leaves in build_diag_value
- Env-gated dump methods (FOXHUNT_DETERMINISM_DEBUG_PER/MAMBA2/RL/BACKWARD)
for future divergence-chasing — never run in production

- Adjacent specs/plans/notes from the analytical chain that surfaced determinism
as the load-bearing blocker (eval-summary, eval-boundary, regime-observer,
multi-head policy, regime-invariance, Phase 3 IQN-complement post-mortem)
Unlocks: every controller / architecture / reward-shaping A/B from this commit
onward attributes outcome differences to the change, not random-init kernel-race
drift cascading through training x eval LOB-sim trajectories. The eval-collapse
investigation (pearl_reward_signal_anti_aligned_with_pnl, multi-head spec,
regime-invariance spec) is now testable with trustworthy verdicts.

ml_core::cuda_autograd::init::generate_uniform (backing xavier_uniform,
kaiming_uniform, bias_uniform, near_zero_xavier) defaulted to seeding
from SystemTime::now() + thread_id, producing non-reproducible weights
across processes. Mamba2 stacks initialise via OwnedGpuLinear::xavier,
which routes through this helper — so PerceptionTrainer.evaluate output
diverged 5-30% across fresh-process runs with identical cfg.seed.
Fix: thread-local seedable RNG override. New API:
let _g = ml_core::cuda_autograd::init::scoped_init_seed(seed);
// ... all xavier/kaiming/bias/near_zero calls draw from
// StdRng::seed_from_u64(seed) chain while _g is alive ...
// _g dropped here -> restores default time-based seeding
PerceptionTrainer::new now installs the guard before any Mamba2Block
construction, so the trainer is reproducible from cfg.seed end-to-end.
CfC/VSN/heads already used explicit ChaCha8Rng::seed_from_u64 — only
Mamba2 was affected.
Production behavior unchanged when no guard is set. ml-core: 306 tests
pass, ml-alpha: 34 lib tests pass.
Regression test: crates/ml-alpha/tests/perception_forward_golden.rs
captures bit-exact PerceptionTrainer.evaluate output (loss + 160 probs
on a deterministic seed=42 fixture) into a 644-byte golden file.
Three consecutive runs now produce max_abs_diff=0; pre-fix runs varied
by 0.1-0.3 absolute on individual probs.
.gitignore: added exception for crates/ml-alpha/tests/fixtures/*.bin
so deterministic test fixtures land in repo.

Replaces the falsified per-horizon Q_h pool with a single shared
query Q over an extended key sequence [horizon_tokens; LN_b_out],
producing per-horizon outputs via TFT-style horizon-token mixing.
FORWARD:
scores[i] = Σ_d Q[d] · ext[i, d] (i ∈ [0, N_H + K))
attn = softmax_i(scores)
S[d] = Σ_k attn[N_H + k] · ln_out[k, d] (shared time agg)
ctx[h, d] = attn[h] · horizon_tokens[h, d] + S[d] (per-horizon out)
BACKWARD: full chain rule with softmax-centring; gradients to
horizon_tokens, Q, and ln_out via the saved attn weights.
NVIDIA-grade implementation per feedback_nvidia_grade_perf_for_kernels:
- Warp-shuffle reduce (block_reduce_sum / block_reduce_max helpers)
for all per-d dot products and softmax aggregates.
- Cross-warp reduce uses exactly one __syncthreads.
- Non-divergent shuffles: inactive lanes contribute 0 via ternary.
- Block-per-batch + horizon-loop inside block → grad_ln_out += is
race-free without atomicAdd.
- Smem layout computed at launch: [s_attn(N_H+K); s_warp(N_WARPS);
s_d_S(H) on bwd]. No over-allocation.
LOCAL VERIFICATION (RTX 3050 sm_86):
forward_then_backward_matches_central_difference PASSES 12 numgrad
checks (4 each on horizon_tokens / Q / ln_out) at 5e-2 rel / 5e-3
abs envelope. First-try pass.
NOTE: .gitignore adjusted with narrow allow-rules for crates/ml-alpha/{
cuda,src,tests}/horizon_token_* paths — the broad "*token*" rule
intended for auth tokens was hiding these source files. Explicit
allow keeps the security rule intact while exempting these specific
files.

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 <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 <PATH> 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<SnapshotRow>
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 <FXC> --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.

Adds a parent/child GitLab CI pipeline for ML model training:
- Generator script produces per-model hyperopt/train/evaluate jobs
- Parent pipeline (.gitlab-ci-training.yml) with manual trigger
- NFS-backed ReadWriteMany PVC for shared training outputs
- Hyperopt params wired into training binaries (DQN, PPO, TFT, Mamba2)
- Shared DBN loader eliminates duplicate code across hyperopt adapters
- Supervised hyperopt unified to DBN data (was parquet-only)
Pipeline: hyperopt (4 models) → train (10 models) → evaluate ensemble

Split the build pipeline: one compile-services job builds all 8 service
binaries with PVC-backed sccache, saves as artifacts. Then 9 Kaniko jobs
just package pre-built binaries into slim runtime images (~30s each).
Before: 9 parallel Kaniko jobs each doing full cargo build --release
(~20min each, no sccache, 9x duplicated dep compilation)
After: 1 compile job with sccache (~5min cached) + 9 package jobs (~30s)
- Add compile stage between test and build
- Add Dockerfile.runtime (minimal debian + pre-built binary)
- Add Dockerfile.web-gateway-runtime (Node dashboard + pre-built binary)
- Keep Dockerfile.training via Kaniko (needs CUDA dev image for H100)
- Remove all SCCACHE_BUCKET build-args from service builds
- Use dir:// context for Kaniko (only sends build-out/ dir, not full repo)
