precompute passes data-dir/SYMBOL to match how train_baseline_rl
calls load_all_bars(data_dir, symbol). compile-and-train gets
FOXHUNT_FEATURE_CACHE_DIR env var and --epochs fix.

Reuses compile-training, gpu-warmup, fetch-binary templates from
compile-and-train. Own train step runs train_baseline_rl directly
with --epochs, FOXHUNT_FEATURE_CACHE_DIR, and fxcache validation.
No hyperopt — pure baseline with default params.

- DAG: compile (ci-compile-cpu) + gpu-warmup → train (H100)
- Compiles from source targeting compute cap 90
- fxcache REQUIRED — fails if no .fxcache found
- Error chains printed with {:#} for full cause visibility
- Uses cargo-target-pvc for compile cache + sccache

Dedicated workflow for baseline RL training without hyperopt.
Runs train_baseline_rl binary on GPU node with fxcache.
Fetches pre-compiled binary from MinIO, falls back to PVC.

Each record now starts with an i64 timestamp (nanoseconds since epoch)
before the feature/target/OFI data. v1 records grow from 432 to 440
bytes, v2 from 112 to 120 bytes. The timestamp is always i64 even in
bf16 mode. train_baseline_rl reconstructs bars with real timestamps
instead of placeholders so the walk-forward windower can split by month.

Auto-discovers fxcache via env var or sibling directory. Falls back
to DBN loading if no cache found. Reconstructs aligned bars from
cached targets for walk-forward windowing.

All pods with app.kubernetes.io/part-of=foxhunt get base infra
access. Fixes MinIO log archival timeout for precompute-features
and databento-download workflows. Component-specific policies
still add extra rules (GitLab SSH, external HTTPS, etc.).

Previous 32Gi OOM'd with 148GB of MBP-10 data (61M snapshots ≈ 15GB

Cache key hashes filename + size + mtime instead of full paths.
Resolves mbp10/trades relative paths by walking up from data_dir.
Ensures precompute binary and cargo test produce the same key
regardless of working directory.

Precompute binary now uses calculate_dbn_cache_key_full from the
library instead of its own compute_cache_key. Canonicalize all
paths in the key function so relative/absolute produce the same
key. Walk up parent dirs for sibling feature-cache discovery.

Exact key match only — no fallback to loading unvalidated caches.
On miss, stale .fxcache files are deleted to prevent disk bloat
and confusion from outdated cached data.

Removed 2.6GB of uncompressed .dbn files (derivable from .zst).
Renamed directory to mbp10-fixtures to distinguish unit test
fixtures from training data. Updated all test references to use
.dbn.zst paths directly.

load_training_data() checks for .fxcache in:
1. Explicit feature_cache_dir (set via with_feature_cache())
2. $FOXHUNT_FEATURE_CACHE_DIR env var
3. Sibling feature-cache/ directory next to data dir

Extract standalone functions from DQNTrainer:
- extract_features_from_bars(): 42-dim feature extraction
- extract_ohlcv_bars_from_dbn(): DBN to OHLCVBar conversion
- collect_dbn_files_recursive(): file discovery
DQNTrainer delegates to these, ensuring consistency.
Precompute binary no longer initializes CUDA — runs on any
CPU node (ci-compile-cpu at EUR 0.85/hr vs GPU at EUR 12.60/hr).

DQNTrainer constructor requires CUDA for regime-conditional heads.
Use DQNTrainer::new() (GPU) instead of new_with_device(Cpu).
Set buffer_size=100_000 to satisfy PER minimum threshold.

Adds feature-cache-dir parameter (default: /data/feature-cache) so
the training binary can load pre-computed .fxcache files.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
CLI binary that reads OHLCV + MBP-10 + trades DBN data via DQNTrainer,
runs the full feature extraction pipeline, and writes a .fxcache file
for zero-overhead GPU loading during training. Uses CPU device to avoid
CUDA dependency for data-only workloads.
Also promotes load_training_data() and ofi_features to pub visibility
so the example binary can access them.

3 retries with exponential backoff (2s, 4s, 8s) for transient
connection failures (IncompleteBody/UnexpectedEof). Partial files

Remove runAsUser:1000 so apt-get install ca-certificates works.
Fix double-nested ES.FUT path (output-dir is the schema root, not ES.FUT subdir).

Root cause: ubuntu:24.04 has no CA certificates, rustls-native-certs
fails TLS handshake. Fix: apt-get install ca-certificates before
running download binary. Also add port 80 to network policy for apt.

Integration test now loads imbalance_bar_threshold and ewma_alpha from
config/training/dqn-smoketest.toml. Single source of truth for all
config values. Production threshold lowered to 0.5 for maximum bar yield.

First load: full MBP-10 decompression (~450s for 19G).
Subsequent loads: bincode deserialize (<1s).
Cache key: hash(dir + symbol + threshold + alpha).
Auto-invalidates when any source .dbn file is newer than cache.
Cache failures are non-fatal — falls through to recomputation.

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.

Replace if-let-Ok pattern with #[ignore] test that asserts on results.
Uses CARGO_MANIFEST_DIR to resolve workspace root. Validates bar
ordering, positive volume, valid OHLC. Produces 654 imbalance bars
from Q1+Q2 2024 ES MBP-10 data (448s load time).

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".
8 files, +483/-48 lines. 3 new tests for trade extraction and pipeline.

Remove 8 enable_* from FeatureConfig (ml-features) and 24 from
DQNHyperparameters (ml). All features are always active — no boolean
toggles, no dead conditional branches, no false impression of optionality.
FeatureConfig reduced to single `phase: FeaturePhase` field.
DQNHyperparameters loses 24 fields, downstream conditionals collapsed.
TOML configs cleaned of all enable_* lines.
16 files changed, -461/+181 lines.

templateRef doesn't inherit workflow-level volumes from the referenced

Migrate from training-pipeline (requires pre-built binary-tag) to
compile-and-train (compiles from source). All 3 train templates now

Consistent params: commit-sha + git-branch instead of binary-tag.
