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

- Delete 22 dead/placeholder/broken example files (-3,489 lines code)
- Delete 4 tracked CSV files (-1.1M lines, were accidentally committed)
- Move baseline training data default from data/cache/ to test_data/
- Update 5 unified binary defaults, gitignore, k8s upload comment, docs
- Consolidate all training data under test_data/futures-baseline/

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)

filter-repo stripped the blobs but left tree entries. Remove from
index so .gitignore rules take effect. Adds checkpoints/ to gitignore.
