busybox doesn't support Argo's emissary executor protocol, causing the
wait sidecar to hang indefinitely and hold the GPU allocation. Switch to
foxhunt-runtime which has proper /bin/sh and lets the sidecar detect
container exit. Also adds nvidia-smi check during warmup.

The test-gate script runs under /bin/sh (dash), which doesn't support
${PIPESTATUS[0]}. This caused 'Bad substitution' (exit 2) on EVERY CI
run regardless of test results.
Fix: redirect cargo test to file, capture $?, then cat for log output.
This is POSIX-compatible and correctly captures the test exit code.

1. fxt MCP server tests: set XDG_CONFIG_HOME to writable temp dir

3. ml-labeling fractional_diff: remove sub-1μs latency assertions

The stability penalty (15% of PSO objective) was dead weight:
- Gradient norm threshold of 20,000 NEVER fires because gradient
clipping is at 10.0 and avg raw grad norms are typically 5-50.
- Q-value std threshold of 100 rarely fires with DSR and v_range=[10,50].
Fix: log-scale ramp for gradient (threshold=50, cap=3.0) gives smooth
PSO gradient across the 50→5000 range where clip engagement indicates
instability. Linear ramp for Q-std (threshold=15, cap=3.0).
Also: delete unused smooth_transition() + calculate_exponential_sharpe_incentive()
(-160 lines dead code), fix stale docstring on HFT activity fn args.

MARKET_DIM was set to feature_dim (50 with OFI) but semantically means
raw market feature count (42). The forward kernel doesn't use MARKET_DIM
directly, but the common header requires it. Subtract ofi_dim to get
the correct value: 50 - 8 = 42.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The OFI backtest path used a Candle narrow+cat closure for state
permutation: [market, OFI, portfolio, pad] → [market, portfolio, OFI, pad].
This was the LAST remaining Candle dispatch in the GPU backtest hot path,
causing per-step tensor allocations and Python-like dispatch overhead.
Fix: added ofi_dim parameter to gather_states kernel. When ofi_dim > 0,
the kernel writes [market, portfolio, OFI, pad] directly — zero extra
copies, zero Candle overhead. Both OFI and non-OFI paths now use
evaluate_dqn_graphed() (pure-CUDA forward + CUDA Graph acceleration).
The DQN hyperopt adapter sets ofi_dim=8 when OFI features are detected.
Other callers (PPO, signal adapter) inherit ofi_dim=0 from Default.
Net result: entire GPU backtest evaluation is now Candle-free.

unique_actions was hardcoded to 5 in the GPU backtest path, making the
diversity penalty (0.8 max weight) always return 0.0 — another dead
objective component. CPU backtest path correctly computed it via HashSet.
Added 5-bit bitmask OR-reduction: each thread sets bit(action_id) during
the existing per-step loop, then a single OR-reduction across the block
produces the union. __popc() gives unique count in one PTX instruction.
Memory efficiency: reuses s_sorted shared memory (sequential staging —
OR-reduction completes before bitonic sort overwrites it). No extra
shared memory arrays needed. Output expanded from 13→14 floats/window.
Combined with the previous commit, this restores gradient signal for
100% of the multi-objective function: composite (60%), HFT activity
(25%), stability (15%), and diversity penalty (soft signal).

The metrics CUDA kernel already iterated over actions_history for trade
counting but never counted buy/sell/hold distribution. evaluate_gpu()
hardcoded all three to 0.0, making calculate_hft_activity_score_wave10()
return a constant -5.0 for every trial — PSO searched blind for 25% of
the objective space.
Kernel: 3 new shared-memory reduction arrays (s_buys/s_sells/s_holds),
action counting in existing per-step loop (0,1→sell, 2→hold, 3,4→buy),
output expanded from 10→13 floats/window. Zero extra kernel launches,
zero extra GPU→CPU transfers (piggybacks on existing memcpy_dtoh).
Shared memory: 25 KB (was 22 KB) — well within H100 228 KB/SM limit.

Replace closure-based evaluate() with evaluate_dqn_graphed() for non-OFI
walk-forward backtest path. Extracts DuelingWeightSet from VarMap (branching
or standard dueling) and runs hand-written warp-cooperative CUDA forward
kernel with CUDA Graph capture — zero Candle dispatch overhead per step.
Key changes:
- GpuBacktestEvaluator::stream() getter for weight extraction on eval stream
- DQNAgentType::is_using_branching() / network_dims() for CUDA kernel config
- Hyperopt evaluate_gpu() non-OFI path: extract_dueling_weights_branching()
→ evaluate_dqn_graphed() (CUDA Graph accelerated)
- OFI path: retains Candle closure for state permutation (gather kernel
layout mismatch — future CUDA permutation kernel)
- 66+ GPU hot-path violations hardened to hard errors across DQN/PPO/supervised
- Stripped all gpu-ok suppression comments
- Proper #[cfg(feature = "cuda")] gating for CUDA-only code paths

Convert Device::Cpu fallback patterns to hard errors across all
hyperopt adapters and the Mamba2 trainer. On H100, CUDA must be
available — silent CPU fallback runs at 1/10th throughput.
Models hardened: TFT, Mamba2, TGGN, TLOB, Liquid, KAN, xLSTM,
Diffusion, ContinuousPPO (hyperopt adapters) + Mamba2 (trainer).
Pattern: Device::new_cuda(0).unwrap_or_else(|e| { warn!(...); Cpu })

Eliminate all CPU fallback paths in the PPO trainer, PPO hyperopt
adapter, and DQN hyperopt adapter. On H100, every GPU operation must
succeed or abort — silent CPU fallback runs at 1/10th throughput and
produces stale/inconsistent results.
PPO trainer (5 sites):
- GPU unavailable → hard error (was warn + CPU fallback)
- Collector init, episode reset, collection, weight sync → hard errors
- Test updated: GPU batch limit test expects error without CUDA
PPO hyperopt adapter (8 sites):
- ensure_gpu_data() now returns Result<(), MLError>
- Features/targets upload, collector init, weight sync → hard errors
- gpu_collect_trajectories() now returns Result<TrajectoryBatch>
- Experience collection caller uses ? instead of Option fallback
- GPU backtest failure → hard error
DQN hyperopt adapter (3 sites):
- CUDA synchronize between trials → hard error
- GPU backtest None on CUDA → hard error (upstream of extract_objective)
- extract_objective: panic! on CUDA build if backtest_metrics is None
- CPU backtest path guarded by #[cfg(not(feature = "cuda"))]
continuous_ppo.rs (1 site):
- clip_grads passed &Device::Cpu instead of actor's actual device
- Forces CPU roundtrip for gradient norm computation on every mini-batch
- Fixed: passes `device` (from self.actor.device()) — stays GPU-resident
gpu_experience_collector.rs (1 site):
- cuCtxSetLimit(STACK_SIZE) failure: warn → hard error
- 16KB stack is required — kernel segfaults without it

CPU fallbacks in the GPU training hot path silently degraded to
slow-path execution without any signal to the operator. Convert all
warn!/debug! fallback patterns to return Err(anyhow::anyhow!(...)) so
training fails loudly instead of running on CPU at 1/10th throughput.
Sites hardened: OFI upload, data pre-upload, targets/features CUDA
upload, portfolio sim init/run, episode reset, train step (2 sites),
online/target weight sync, branching head sync (2 sites), RMSNorm
sync (2 sites), action selector init (2 sites), training guard init.
Update test_train_with_empty_data_completes_gracefully to expect
is_err() since empty data now correctly fails at GPU pre-upload.

GPU experience kernel was zero-padding OFI features (state[45..53]),
creating a train/eval mismatch where GPU-collected experiences had no
OFI context but CPU validation used real OFI data.
- Add OFI_DIM compile-time constant to common_device_functions.cuh

- Add ofi_features parameter to both kernel signatures (full + warp)
- Replace zero-padding loop with direct OFI load from GPU memory
- Add upload_ofi_features() method to GpuExperienceCollector
- Wire OFI upload in DQN trainer at collector init time
- Cap MaxDD at 100% in evaluation metrics (margin call boundary)

- Walk-forward CPU backtest was calling feature_vector_to_state() without

- Add convert_to_state_vec_with_ofi() public method on DQNTrainer
- Add ofi_val_offset field to track training data length for OFI indexing
- compute_validation_loss() now passes OFI index to validation states
- Hyperopt CPU eval path now uses convert_to_state_vec_with_ofi()
- Enable DSR (Differential Sharpe Ratio) by default in both config and
GPU experience collector — aligns with hyperopt which always uses DSR
- Fix ensemble adapter test to explicitly disable branching

`self.hyperparams.use_branching` at both GpuExperienceCollector::new

NVRTC does not include <stdint.h> so uint64_t is undefined. The TMA
mbarrier shared variable was causing 5 compilation errors on the H100
(identifier "uint64_t" is undefined, asm operand must have scalar
type). Using the native CUDA type unsigned long long (also 64-bit)
resolves the issue without needing any NVRTC headers.

These dimensions MUST be injected via NVRTC dim_overrides (which always
happens in gpu_experience_collector.rs). Having fallback #ifndef defaults
(48/42/3) masked bugs when source concatenation order was wrong and is
misleading since STATE_DIM varies (48 without OFI, 56 with OFI). Now
a missing dim_override triggers a compile-time #error instead of
silently using a stale default.

The exact f64 equality check was failing intermittently due to

Previously hardcoded state_dim=48 in both VRAM gates (bounds
computation and per-trial check). With OFI features enabled (the
production path), aligned state_dim is 56, causing VRAM estimates to
be ~17% too low. Trials that should be pruned could pass and OOM.
- Per-trial VRAM check: uses self.mbp10_data_dir to select 56 or 48
- Bounds computation (static fn): uses worst-case 56 (safe for all)

The hyperopt binary was crashing with "trials (5) must be greater than
n_initial (5)" when --trials 0 was passed. Root cause: the bump logic
set trials = n_initial instead of max(5, n_initial + 1).
Fix: both hyperopt_baseline_rl and hyperopt_baseline_supervised now clamp
trials to max(5, n_initial + 1). Also add `when` condition to the
compile-and-train DAG so hyperopt step is skipped when trials=0, and
train-best gracefully handles missing hyperopt results.

When trials=0 (or any value <= n_initial), both RL and supervised
hyperopt binaries now auto-bump to n_initial+1 instead of bailing.
Previously the RL binary bumped to 5 which equalled n_initial=5,
triggering "trials must be greater than n_initial" error. The
supervised binary lacked the bump entirely and just crashed.

Both walk-forward and full-training data loading paths now use rayon
par_iter to parse MBP-10 .dbn files concurrently. Previously 9 files
were parsed sequentially (~4 min on H100); parallel loading gives
~7-9x speedup proportional to file count. Trade file loading also
parallelized. Removed dead collect_dbn_files helper (superseded by
collect_dbn_files_recursive at module scope).

Three root causes of CUDA_ERROR_INVALID_PTX on H100 addressed:
1. TMA busy-wait label: cooperative_load_tile_tma used a named PTX label
(TMA_WAIT:) in a __forceinline__ function inlined at ~28 call sites,
producing duplicate labels in the same PTX function. Replaced with a
C while loop + selp.b32 to extract the try_wait predicate — no PTX
labels emitted.
2. mbarrier wait scope: only thread 0 waited for TMA completion while
lanes 1-31 skipped the entire function body. Now all 32 lanes
participate in mbarrier.try_wait.parity.acquire, with __syncwarp()
fences before and after to handle Hopper independent thread scheduling.
3. Dead per-thread functions: q_forward_dueling, q_forward_branching,
q_forward_distributional, q_forward_dueling_noisy, and their _shmem
variants were compiled into sm_90 PTX despite never being called by
the warp kernel. q_forward_distributional alone allocates 600 floats
(2.4KB) per thread. Guarded all three groups with
#if __CUDA_ARCH__ < 900 to eliminate ~7KB dead stack from PTX.
Also: removed NUM_ATOMS_MAX=51 cap (no longer needed since distributional
per-thread function is excluded), moved dim_overrides before common_src
to avoid NVRTC macro redefinition warnings.
