Smoke and localdev profiles previously used data_source = "ohlcv", divergent
from production (mbp10). Mismatch silently produced cache-key collisions in
the SHA256 hash path: smoke fxcache could not be loaded by production-shape
training without an explicit override. Local-dev fxcache regen also required
remembering to pass --data-source ohlcv to match.
Globalize mbp10 as the default everywhere it isn't deliberately overridden:
- config/training/dqn-smoketest.toml: data_source = "mbp10"
- config/training/dqn-localdev.toml: data_source = "mbp10"
- training_profile.rs: doc Default → "mbp10"
- trainers/dqn/config.rs: Default impl → "mbp10"
- hyperopt/adapters/dqn.rs: default → "mbp10"
- examples/precompute_features.rs: doc updated
- fxcache.rs / feature_cache.rs: discover_and_load + cache-key tests
use "mbp10" arguments
- docs/dqn-wire-up-audit.md: new entry per Invariant 7
Documentation strings retained "ohlcv" only where they document the two
available choices (config.rs:946, training_profile.rs:83).
Local fxcache regenerated to v6 mbp10:
test_data/feature-cache/13c0b086a975cc7e2384377a2cd0e97738c9410292fcfecb5807c29bf885cb48.fxcache
(175874 bars, 55 MB, OFI_DIM=32). Stale v5 ohlcv fxcache untracked
from git index (already gitignored post-79578bbaf).

fix kernel-read gap
Adds 12 features to the DQN input pipeline:
- 10 MicrostructureState::snapshot()[0..10] slots that were previously computed
every bar and then discarded before reaching fxcache: ofi_trajectory,
realized_variance, hawkes_intensity, book_pressure (weighted 10-level),
spread_dynamics, aggression_ratio, queue_depletion_asymmetry,
order_count_flux, intra_bar_momentum, regime_score.
- 2 TLOB-novel slots derived directly from Mbp10Snapshot:
order_count_imbalance = (Σbid_ct − Σask_ct) / Σ(bid_ct + ask_ct),
microprice_residual = (weighted_mid − mid) / mid.
Also fixes a production gap: ofi_acceleration (slot 18) and
toxicity_gradient (slot 19) were persisted to fxcache via OFI_DIM=20
but the OFI embed kernel (experience_kernels.cu:6146-6173) only read
[0..18), silently discarding them every bar. Kernel extended to
consume full SL_OFI_DIM=32.
Dimension bumps (all 8-aligned):
OFI_DIM 20 → 32
FXCACHE_VERSION 4 → 5 (invalidates existing caches; regen via
precompute_features)
STATE_DIM 96 → 104
PADDING_DIM 4 → 0 (OFI expansion consumed padding, still 8-aligned)
STATE_DIM_PADDED 128 (unchanged)
OFI_EMBED_IN 18 → 32 (MLP input width; W/grad/Adam/m/v buffers
resized in lockstep via named constants)
fxcache regen results (175874 bars ES.FUT 2024-Q1):
deltas_nonzero: 175781 / 175874 (99.9 percent)
book_aggression: 102137 / 175874 (58.1 percent)
microstructure[20-30): 175874 / 175874 (100 percent)
tlob_novel[30-32): 133615 / 175874 (76.0 percent)
Compile status: SQLX_OFFLINE=true CARGO_INCREMENTAL=0 cargo check
--workspace --tests passes cleanly (0 errors, pre-existing warnings
only).
Test results:
fxcache roundtrip (unit + integration): PASS (4+6 tests)
magnitude_distribution smoke: ran through epoch 1 successfully
(OFI_DIAG fires, state_dim=104 confirmed, feature_dim=74 in
validation kernel); epoch 2 OOM on local RTX 3050 Ti (4 GB) —
expected hardware limit from state_dim growth. Full 20-epoch run
requires L40S/H100 CI verification.
multi_fold_convergence smoke: not verified locally (same VRAM
ceiling applies). L40S/H100 CI verification required.
The new slots follow the existing OFICalculator/MicrostructureState
pattern and consume signals already computed by ml-features — no new
crate, no ONNX, no stubs. All 12 sources were audited against their
implementation before persistence; every slot traces back to real
Mbp10Snapshot or MicrostructureState math.

- OFI_DIAG now reads positions [42..62) using OFI_START constant instead of
hardcoded [66..74). Verified: raw_mean=0.0891, delta_mean=-0.0370,
book_agg=0.4500, log_dur=-0.2303 (was all zeros before).
- Removed 3 stale state_dim field initializers from evaluate_baseline.rs.

Both destabilized H100 training:
- Reward normalization (÷pos_frac): collapsed gradients at epoch 2-3
- Magnitude gradient restore (beta*MSE): Q-value explosion at epoch 25
(tested beta=0.10, 0.05, 0.02 — ALL cause Q explosion >50)
The magnitude MSE gradient is structurally unstable post-warmup.
ANY non-zero beta feeds a Q-overestimation loop that CQL can't counter.
The magnitude branch head learns during MSE warmup (epochs 1-5), then
the trunk continues improving via IQN (60% budget). This is the ONLY
stable configuration proven on H100 (RUN 4: stable through 9 epochs,
grad_norm=0.44, Q=2.03).
Reverts 76478559b (reward norm) and 22b7bc083 (gradient restore).
Keeps 1540c0287 (CUDA Graph fixes — the critical root cause).

GpuBatch now stores raw u64 device pointers to pre-allocated replay
buffer memory. Eliminates per-step:
- 14 cuMemAlloc calls (7 in sample_proportional + 7 in into_gpu_batch)
- 14 DtoD copies (clone into owned CudaSlice)
- CPU staging Vec and flush() dead code path
Also removed: GpuBatchSlices, into_gpu_batch, dtod_clone_* helpers,
StagedGpuBuffer.staging field, CPU add/add_batch for GpuPrioritized.
update_priorities_cuda now takes u64 raw pointer.
HER relabel_batch_with_strategy takes u64 episode_ids_ptr.
Cold-path Q-value estimation uses compute_q_stats_internal.

Root cause 1 — CUDA_ERROR_ILLEGAL_ADDRESS:
shmem_max_in_dim only included trunk dims (state_dim, shared_h1,
shared_h2) but not head dims (value_h, adv_h). BF16 weight tile
for branch output overflowed shared memory on RTX 3050 (48KB).
Root cause 2 — CUDA_ERROR_INVALID_VALUE on EMA kernel:
cudarc 0.17's automatic event tracking records read/write events on
CudaSlice buffers. During CUDA Graph capture (events disabled) then
replay (events re-enabled), stale write events from CudaSlice Drops
poison the context error_state. Next bind_to_thread() propagates it.
Fix: disable_event_tracking() at GpuDqnTrainer construction —
single-owner forked stream, all sync points are explicit.
Also:
- Remove all #[ignore] from smoke tests, use real ES.FUT .dbn data
- Validate DBN schema at file level (skip non-OHLCV)
- Organize test_data/ into per-symbol subdirectories
- Fix pre-existing gpu_kernel_parity_test + evaluate_baseline errors

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)
