With separate optimizer, no gradient competition — safe to increase.
Smoke test shows within-group differentiation starting (S100≠S25≠L50).

The exposure aux backward GEMM amplifies gradients through the
hidden activation matrix (d_logits × h_b0), producing grad_norm=5000+.
With max_grad_norm=10, this throttles ALL gradients by 500x (lr/500).
Fix: reduce aux_weight 0.5→0.01 (50x) + clip_grad_buf_inplace after
aux GEMM to cap combined gradient at max_grad_norm.

- Exposure aux kernel -> f32 scratch -> bf16 cast -> backward_fc_layer GEMM
- Weight + bias gradients accumulated into grad_buf (pure GPU, zero CPU sync)
- CEA warmup: linear decay 1.0->base over 25% of epochs
- OFI epoch gate: disabled for first 5 epochs
- Exposure aux decay: base -> 10% over warmup_epochs
- Removed dead v6 fields: loss_aversion, beta_penalty, regret_blend, trade_clustering_penalty
from ExperienceCollectorConfig (kernel no longer reads them)

All training parameters now explicit in the TOML — no implicit defaults.
- batch_size=8192: maximizes H100 tensor core utilization
- max_bars=0: unlimited (train on full dataset)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- mbp10_data_dir: /mnt/training-data → /data/futures-baseline-mbp10
- Add missing trades_data_dir: /data/futures-baseline-trades
- Paths now match Argo workflow PVC mount at /data (CLI overrides still work)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add mbp10_data_dir and trades_data_dir to smoketest TOML profile
- Fix data_loading path resolution: resolve relative paths against
workspace root via CARGO_MANIFEST_DIR (CWD is crates/ml during tests)
- Add buffer_size floor of 1024 in hyperopt adapter (GPU PER minimum)
- Regenerated fxcache with full OFI features (MBP-10 + trades)
All tests now consistently hit fxcache with OFI=true.

- Reduce max_bars from 60000 to 5000 (smoketests ran 16min, now ~1min)
- Fix test_counterfactual_experiences_in_buffer: compute threshold from
actual config instead of hardcoded 4000, enlarge buffer to avoid wrap
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Smoketest sets max_bars=60000 (~1 quarter). Applied in load_training_data()
on both fxcache and DBN paths. 0 = unlimited (production).

The GPU PER segment tree works with any power-of-2 capacity. The
arbitrary 1024 floor prevented small buffer sizes needed for fast
smoketests. Now the minimum is batch_size (can't sample more than
buffer holds).

Smoketest profile: 1.0 → 0.1 (mild conservatism, no NaN).
Healthy training test: disable CQL entirely (cql_alpha=0.0) since this
test validates training completion, not CQL behavior.

Remove data_source=mbp10 and mbp10_data_dir from dqn-smoketest.toml so
smoketests load OHLCV data instead of the non-existent MBP-10 test path.
Update stale test assertions: epochs 3→10, production mbp10_data_dir to
/mnt/training-data path, and a second epochs assertion in
test_toml_profile_applies_all_fields.

- smoketest: epochs=3→10, c51_warmup_epochs=5 — C51 now activates at
epoch 6 (was never reached with 3 epochs)
- production: mbp10_data_dir → /mnt/training-data/futures-baseline-mbp10
(PVC mount path, was pointing to local test_data)
- production smoketest uses TOML epochs (no hardcoded override)

1. capture_training_graphs had cuStreamSynchronize before begin_capture
which hung when stream had stale state from experience collection.
2. Training profile apply_to must apply batch_size so smoketest TOML
(batch_size=64) overrides the conservative default (1024).
3. Removed batch_size from dqn-production.toml — GPU profile is authority.
4. Removed all debug eprints.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
dqn-production.toml batch_size=8192 was overriding GPU profile batch_size=64
on RTX 3050 via apply_to(), causing OOM/hang. GPU profile is the sole
authority for batch_size — training profile controls learning params only.

Three bugs causing the baseline RL training to hang on first epoch while
smoketest completes in 1.2s:
1. VRAM oversubscription (hang root cause): detect_gpu_hardware auto-scaling
computed n_episodes without accounting for 2x counterfactual doubling or
dtod_clone allocations, causing 4x actual memory vs budget. Replaced with
configurable gpu_n_episodes field (smoketest=32, localdev=128, prod=4096).
2. Counterfactual experiences silently dropped: build_next_states_f32 received
n_episodes instead of n_episodes*2, and PER insert used base count instead
of doubled count — ~50% of augmented training data was generated then lost.
3. CudaEvent leak in hot loop: record_event(None) created+destroyed 8000 events
per epoch in forward_online_raw/f32. Pre-allocated 4 events in CublasForward
struct, eliminating driver overhead and handle leaks during CUDA Graph capture.

Was 0 (auto) which bypassed profile and hit broken AutoBatchSizer.
All configs now have explicit tested batch_size values.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Epoch duration self-balances: bigger GPU → bigger auto-scaled batch →
fewer steps per epoch. The manual cap created 7 different values
(0, 8, 64, 100, 200, 300, 2000) across configs/tests/examples, making
behavior inconsistent between environments.
Removed from: DQNHyperparameters, training profiles (smoketest,
localdev, production), CLI args, Argo templates, hyperopt adapter,
all test overrides, supervised example.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
gpu_n_episodes was manually overridden in GPU profiles, training configs,
test files, and hyperopt — all set to 0 or small fixed values that
bypassed the auto-scaling logic, causing a div-by-zero crash in
train_baseline_rl.
Now: single auto-scaling path via optimal_n_episodes() from VRAM/SM
count. No manual override field. Cap at 16384 (consistent with
AutoBatchSizer's 8192 cap pattern). Floor at 32 for small GPUs.
Removed gpu_n_episodes from:
- DQNHyperparameters, PpoHyperparameters structs
- All 4 GPU profiles (rtx3050, h100, a100, default)
- Training profiles (smoketest, localdev)
- ExperienceProfile struct + serde
- Hyperopt adapter
- All test overrides

The batch_size >128 hang was caused by cudarc's synchronous
memcpy_htod for the adam_step counter. At batch_size=128 the
sync completes fast enough, but at 509+ the pipeline drain
from the sync interacts with CUDA Graph replay timing and
deadlocks the stream.
Replaced all 3 memcpy_htod(&[self.adam_step]) calls with raw
cuMemcpyHtoDAsync_v2 — zero pipeline drain, zero CPU sync.
Production TOML set to batch_size=0 (AutoBatchSizer drives it).
AutoBatchSizer caps at 8192 for RL training.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
batch_size=1024 has never been tested on H100. It was always
overridden by the CLI default (128) in all previous runs.
Our changes exposed this latent bug by conditional batch_size
override logic.
Root cause of the hang is unknown (likely CUDA Graph capture
with batch_size=1024 buffers). Setting to known-working 128
while we investigate. The batch_size=1024 hang investigation
is tracked in the mega-graph refactor plan.

Set batch_size=0 in config/gpu/h100.toml as sentinel for auto-compute.
The constructor now treats batch_size==0 as "let AutoBatchSizer drive":
it uses the VRAM-computed ceiling capped at 8192, instead of the static
1024 that was wasting >90% of H100's 80GB VRAM bandwidth.
Previously AutoBatchSizer computed the optimal batch (e.g. 2085808) but
the profile's batch_size=1024 always won. Now with batch_size=0 the
sizer's result flows through, enabling full SM occupancy on H100.

Relative TOML paths now resolved via CARGO_MANIFEST_DIR → workspace root,
matching test_data_dir() behavior. MBP-10 smoke test passes: 654 imbalance
bars from Q1+Q2 2024, threshold=25.0.
Smoketest config switched to data_source="mbp10" for MBP-10 validation.

Wire MBP-10 order book data through ImbalanceBarSampler into the DQN
training pipeline. No fallback — explicit data_source config: "mbp10"
(imbalance bars from 10-level order book) or "ohlcv" (1-minute candles).
Fails loudly if chosen source's data doesn't exist.
Pipeline: MBP-10 .dbn.zst → trade extraction (action=='T', native side
classification) → adaptive ImbalanceBarSampler (EWMA threshold) →
OHLCVBar → existing feature extraction.
Production: data_source="mbp10", smoketest/localdev: data_source="ohlcv".

Remove 8 enable_* from FeatureConfig (ml-features) and 24 from
DQNHyperparameters (ml). All features are always active — no boolean

FeatureConfig reduced to single `phase: FeaturePhase` field.
DQNHyperparameters loses 24 fields, downstream conditionals collapsed.
TOML configs cleaned of all enable_* lines.

Fix mbp10_data_dir/trades_data_dir TOML→DQNHyperparameters wiring gap.
Fields were deserialized but silently dropped — now applied in
training_profile.rs apply_to(). Production TOML activates OFI (8 features
from MBP-10 order book), smoketest leaves it off for fast iteration.
3 new OFI integration tests: state vector positioning, graceful
degradation (zero-fill without MBP-10), feature name ordering.

Phase 1: Remove 5 DQNConfig boolean flags (use_soft_updates, use_iqn,
enable_q_value_clipping, use_cvar_action_selection, use_count_bonus).
All features now unconditionally active — no dead toggle branches.
Phase 2: Add spectral decoupling (L2 on Q-value logits, Pezeshki 2021)
and manifold mixup (Beta-sampled distribution interpolation with atomic
barrier sync) directly in C51 CUDA loss kernel. Zero CPU involvement.
Phase 3: Tag Experience transitions with market regime (ADX/CUSUM GPU
classifier kernel). Add regime-biased PER sampling via rejection with
IS weight correction. Decay factor controls cross-regime bleeding.
Phase 4: 6 family intensity scalars for hyperopt (adversarial,
regularization, augmentation, loss shaping, ensemble, causal). Scales
34 generalization params through 6 PSO dimensions instead of 34.
Search space: 24D → 30D (families additive, individual params kept).
