jgrusewski	200f05fcef	fix(sp14-B.11): move EGF producer chain into per-step training loop — fixes per-epoch staleness ... Root cause from train-v8ztm 10-ep validation (commit 1396b62ec): HEALTH_DIAG showed alpha_smoothed=0.0002 (vs ~0.5 expected steady-state), gate1=closed, var_aux:var_q ratio 290:1 — symptoms of an EGF producer chain firing < 1% as often as the consumer. The original B.11 wire-up (commit 857722e77) placed `launch_sp14_q_disagreement_update`, `launch_sp14_alpha_grad_compute`, and the prerequisite `launch_sp13_aux_dir_metrics` in `process_epoch_boundary` — which runs ONCE per epoch (single call site at training_loop.rs:780, called from the per-epoch loop, not from the per-step loop in `run_training_steps_slices`). The captured backward consumer `launch_sp14_scale_wire_col` (inside launch_cublas_backward_to, replays every training step via parent graph) reads ISV[ALPHA_GRAD_SMOOTHED=393] per step, but the producer was firing only at epoch boundary — every step inside the epoch observed (steps_per_epoch − 1)-step-stale alpha values, with the EMA chain barely accumulating past sentinel between rare per-epoch updates. The plan §2550 explicitly specifies per-step cadence; the existing wire violated the plan. Fix (atomic, graph-capture-safe): - MOVED launch_sp13_aux_dir_metrics, launch_sp14_q_disagreement_update, launch_sp14_alpha_grad_compute from process_epoch_boundary into fused_training.rs:submit_aux_ops, immediately after populate_q_out. submit_aux_ops captures into the aux_child sub-graph, so each parent-graph replay re-fires the full producer chain — restoring per-step cadence. - launch_sp13_aux_dir_metrics had to migrate alongside the SP14 launches: alpha_grad_compute_kernel consumes its outputs (ISV[373/374]); leaving sp13 per-epoch while moving SP14 per-step would re-introduce the same staleness bug for aux_dir_acc reads (atomic dependency migration per feedback_no_partial_refactor). - Per-epoch launch_sp14_gradient_hack_detect circuit breaker stays in process_epoch_boundary — its lockout decrement IS one-per-epoch by design. - Forward consumers (6 launch_sp14_dir_concat_qaux sites) and backward consumers (2 launch_sp14_scale_wire_col sites) unchanged — they read the same ISV[393], but now see live per-step values instead of per-epoch staleness. Verification: - cargo check -p ml --tests --all-targets clean (no errors, no new warnings). - All 6 SP14 oracle GPU tests pass (alpha_grad_adaptive_beta, alpha_grad_schmitt_hysteresis, dir_concat_qaux_correct, gradient_hack_circuit_breaker_fires, q_disagreement_all_hold_no_contribution, q_disagreement_k4_k2_mapping). - HEALTH_DIAG validation pending L40S re-dispatch — expect alpha_smoothed to track real EGF-driven values (~0.5 in steady state). Invariants: - pearl_no_host_branches_in_captured_graph (kernels are pure GPU state machines using launch_builder + pre-loaded CudaFunction; no per-call load_cubin) - feedback_no_partial_refactor (sp13 + 2 SP14 launches migrated atomically) - feedback_wire_everything_up (all 3 producers now production hot-path, re-fire on every parent-graph replay) - feedback_isv_for_adaptive_bounds (no warmup_gate parameter — variance- driven k_aux/k_q in alpha_grad_compute_kernel handles cold-start adaptively, per c0fc28e45) Refs: train-v8ztm trajectory analysis 2026-05-07T15:59:49 HEALTH_DIAG[10] showed dir_entropy=0.6545 kill-fast breach with model converging to 64% Hold + 84% Quarter magnitude — exactly the pathology B.11 was designed to prevent by routing aux's directional signal into Q.

jgrusewski	1396b62ec6	fix(sp15-wave5-followup): pre-load sp15_baseline + cost_net cubins — fixes hyperopt-trial CUDA_ERROR_ILLEGAL_ADDRESS ... Root cause: 5 SP15 evaluation launchers (cost_net_sharpe + 4 baseline_*) were doing `load_cubin` + `load_function` PER-CALL inside `GpuBacktestEvaluator`'s eval hot loop. Pattern is fragile across CUDA context lifetimes — works in single-pass train-best context (smoke train-9bcwm verified), fails in hyperopt-trial child stream context (workflow train-xggfc trial 1 failed at "load sp15_baseline_kernels cubin: ILLEGAL_ADDRESS"; after the host-side load corrupted the trial's context, trials 2-20 all cascade-failed at "Fork CUDA stream for trial"). Fix (atomic, matches 5d63762ab precedent for bn_tanh_concat_dd): - Add 5 `CudaFunction` fields on `GpuBacktestEvaluator`. - Pre-load both `SP15_BASELINE_KERNELS_CUBIN` (4 functions) and `SP15_COST_NET_SHARPE_CUBIN` (1 function) once in `GpuBacktestEvaluator::new()`, alongside the existing `env_module` / `metrics_module` loads. - Change all 5 launcher signatures in `gpu_dqn_trainer.rs` to take `&CudaFunction` instead of doing per-call cubin load. - Update all 5 call sites in `gpu_backtest_evaluator.rs:2877..2922` to pass `&self.sp15_*_kernel`. - Update 4 oracle test call sites in `crates/ml/tests/sp15_phase1_oracle_tests.rs` (cost_net + 4 baselines) to pre-load and pass the kernel handle directly, matching 5d63762ab's pattern for `DQN_UTILITY_CUBIN`. - Update Invariant 7 audit doc (`docs/dqn-wire-up-audit.md`). Verification: `SQLX_OFFLINE=true CUDA_COMPUTE_CAP=86 cargo check -p ml --tests --all-targets` clean (warnings only, no errors).

jgrusewski	5d63762ab3	fix(sp15-wave4.1b-OOB-followup): pre-load bn_tanh_concat_dd_kernel — fixes forward-capture SEGV ... Root cause: SP15 Wave 4.1b (eb9515e41) migrated the trainer's 3 production bottleneck-concat call sites (online forward, target forward, DDQN argmax) from the pre-loaded `bn_tanh_concat_kernel: CudaFunction` field to a `launch_sp15_bn_concat_dd` free function that resolved the symbol via `load_cubin` + `load_function` ON EVERY CALL. That pattern is incompatible with CUDA Graph capture: `cuModuleLoadData` and `cuModuleGetFunction` are HOST-side driver API calls that allocate memory and mutate driver state, and they are NOT capturable inside a `cuStreamBeginCapture` region. Calling the launcher from `submit_forward_ops_main` (graph-captured forward child) caused a SEGV at exit 139 — the loader raced with the capture-mode driver state, the host-side corruption surfaced as a segfault before `CAPTURE_PHASE_FORWARD_DONE` could print. Diagnostic evidence (L40S smoke `train-vg5f7` on commit `bfc3ffa9d`): ALL 16 step-0 ungraphed checkpoints printed clean. Capture begins: CAPTURE_PHASE_BEGIN CAPTURE_PHASE_PER_SAMPLE_DONE CAPTURE_PHASE_COUNTERS_DONE CAPTURE_PHASE_SPECTRAL_DONE Then: SEGV. The next checkpoint that didn't print was CAPTURE_PHASE_FORWARD_DONE -> SEGV is inside `submit_forward_ops_main`'s `forward` child capture. The same function ran cleanly ungraphed in step 0 because the loader-host-branch was harmless without active capture. The experience collector's equivalent caller (gpu_experience_collector.rs:4127) was already doing this correctly — pre-loaded `bn_tanh_concat_fn` field populated at construction. Wave 4.1b's mistake was asymmetric: it kept the collector's pre-load pattern but introduced an on-demand loader for the trainer's call sites. Fix (atomic, restores graph-safe contract): - Add `bn_tanh_concat_dd_kernel: CudaFunction` field on `GpuDqnTrainer` (back-fills what Wave 4.1b removed, with updated docstring naming the new dd_pct-aware kernel). - Pre-load the symbol in `compile_training_kernels` from the same `module` as `bn_tanh_bw` / `bn_bias_grad` (forward-child captured replay group). Tuple grows 43 -> 44 CudaFunctions; struct ctor wires the field. - Change `launch_sp15_bn_concat_dd` signature to take `&CudaFunction` as parameter; remove the per-call `load_cubin` + `load_function`. All 3 trainer call sites pass `&self.bn_tanh_concat_dd_kernel`. - Promote `DQN_UTILITY_CUBIN` from `pub(crate)` to `pub` so the oracle tests in `crates/ml/tests/sp15_phase1_oracle_tests.rs` can pre-load the kernel handle (the launcher no longer hides this for them). - Update the 2 test call sites (kernel-level oracle + Wave 4.1c behavioral KL test) to load the kernel handle once up-front and pass it through. Verification: - `cargo check -p ml --tests` clean (release + dev profile). - `cargo test -p ml --test sp15_phase1_oracle_tests -- --ignored`: 36/36 pass, including the Wave 4.1c behavioral KL test that exercises two end-to-end forward passes through the modified launcher.

jgrusewski	bfc3ffa9dc	diag(sp15-wave5): in-capture CAPTURE_PHASE_* checkpoints ... Smoke train-fp7xx printed all 16 Phase-6/7/8 checkpoints clean through PER_PRIORITY_DONE. CAPTURE_DONE missing, exit changed 139→143 (SIGTERM) — capture_training_graph hangs or takes ~40s past PER_PRIORITY_DONE before Argo terminates the pod.

jgrusewski	e9d9afbd61	diag(sp15-wave5): stderr checkpoints in run_full_step step-0 ungraphed path ... L40S smoke train-jfbzr (commit 23e9a1f78) segfaults at exit 139 in the first run_full_step invocation, after "GPU training guard initialized (epoch loop)" and before any HEALTH_DIAG output. Static analysis debugger couldn't reproduce locally (test_data/futures-baseline/ lacks .fxcache). This commit adds eprintln! checkpoints at each phase boundary in the ungraphed step-0 path of FusedTrainer::run_full_step (PER sample, PopArt, counters, spectral norm, TLOB forward, forward_main, DDQN, aux_ops, post_aux, NaN checks). stderr is line-flushed (vs stdout buffered through tracing JSON formatter), so the last printed checkpoint identifies the SEGV site. Each fires once per fold's first step (graph capture absorbs subsequent steps), so log overhead is minimal. Diagnostic-only commit — no behavior change. Will be reverted after the next L40S smoke localizes the SEGV and the root-cause fix lands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-07 12:21:12 +02:00
jgrusewski	23e9a1f78c	fix(cuda): compute_expected_q stride 13 vs denoise_target_q_buf size 12 — OOB writes threads 60-63 ... Pre-existing latent bug surfaced by compute-sanitizer after the SP15 NULL-pointer fix at 2e37af29d unblocked the cascade. Threads 60-63 were writing past denoise_target_q_buf's end every batch. Sanitizer evidence (pre-fix on 2e37af29d): Invalid __global__ write of size 4 bytes at compute_expected_q+0x2480 by thread (60..63, 0, 0) in block (0, 0, 0) Access at <addr> is out of bounds (45/97/149/201 bytes after nearest allocation of size B*12*4 bytes) Host backtrace: GpuDqnTrainer::compute_denoise_target_q → submit_post_aux_ops → run_full_step Root cause — semantic mismatch between writer stride and buffer size: - compute_expected_q writes q_values[i*total_actions + a] with total_actions = b0+b1+b2+b3 = 4+3+3+3 = 13 (4-direction factored) - denoise_target_q_buf was allocated b*12 (legacy 3+3+3+3 layout) - threads 60..63 wrote slot 12 of samples (60..63 % batch_size) past the buffer end every step The downstream q_denoise_backward + denoise_loss_grad kernels read Q_target[b * D + i] with hardcoded D=12 because the diffusion denoiser MLP itself only has 12 output slots (W2[12,24] + b2[12]) — its 12 are the q_coord_buf's post-cross-branch-attention narrowed output, NOT a clean subset of the 13 raw Q-actions. The exact same fix pattern was already applied to the sibling q_var_buf_trainer allocation in the prior SP4 audit (see comment block at gpu_dqn_trainer.rs:21620-21630 referencing the identical OOB at threads 60..63); denoise_target_q_buf 8 lines below was missed because it was guarded by the SP15 NULL-pointer ILLEGAL_ADDRESS that fault- stopped the cascade before this OOB could fire — 2e37af29d removed the upstream ILLEGAL_ADDRESS, surfacing the latent OOB. Fix architecture (Option A — pad buffer to total_actions, pass stride to consumer; same pattern as q_var_buf_trainer): 1. Widen denoise_target_q_buf from b*12 to b*total_actions (= b*13) to match compute_expected_q's writer stride. 2. Add refined_stride / target_stride / input_stride parameters to q_denoise_backward kernel; the kernel still computes D=12 per- sample (denoiser MLP fixed width) but addresses each input buffer at its own per-sample stride. 3. Add refined_stride / target_stride parameters to denoise_loss_grad kernel (same pattern; used by launch_q_denoise_backward_cublas). 4. Update both Rust launchers (launch_q_denoise_backward, launch_q_denoise_backward_cublas) to pass refined_stride=12 (q_coord and q_input are post-attention narrowed), target_stride=total_actions=13. 5. denoise_q_input_buf STAYS at b*12 — it's a snapshot of q_coord_buf (also b*12) via snapshot_pre_denoise_q's DtoD copy; never written by compute_expected_q. 6. Flat-scan consumers (SP4 target_q_p99_update producer + SP3 slot 46 threshold-check + dqn_clamp_finite_f32) UNCHANGED — they consume the buffer flat via .len(); widening from b*12 to b*13 is monotone (one more valid Q-value per sample in the histogram). Atomic per feedback_no_partial_refactor: 2 kernel signatures + buffer allocation + 2 launch sites + struct doc comments + SP3 slot 46 doc + audit doc — all in one commit. Every consumer of the writer's stride migrates simultaneously. Verification: - SQLX_OFFLINE=true cargo check -p ml --features cuda: clean - compute-sanitizer (RTX 3050 Ti): 0 Invalid __global__ errors at compute_expected_q post-fix (down from 4 per training step in baseline — re-verified on 2e37af29d to confirm the diff) - SQLX_OFFLINE=true cargo test -p ml --features cuda --lib: holds parent baseline 947 pass / 12 fail (same 12 pre-existing failures) Files touched: crates/ml/src/cuda_pipeline/experience_kernels.cu — q_denoise_backward + denoise_loss_grad kernel signatures crates/ml/src/cuda_pipeline/gpu_dqn_trainer.rs — alloc widen + 2 launcher updates + 4 doc comment updates docs/dqn-wire-up-audit.md — audit entry Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-07 11:39:34 +02:00
jgrusewski	2e37af29d4	fix(sp15-p1.3.b-followup-OOB): wire ISV bus + SP15 control pointers BEFORE first collect — fixes "load sp15_dd_state cubin" CUDA_ILLEGAL_ADDRESS ... Root cause: Wave 4.1b (s1_input_dim 102→103, eb9515e41) introduced `bn_tanh_concat_dd_kernel` which reads `isv[DD_PCT_INDEX=406]` from the collector's `isv_signals_dev_ptr`. Wave 4.1b's atomic refactor docstring claimed "guarded by the captured-graph wiring in training_loop.rs:859 which sets the bus pointer BEFORE the first epoch's forward graph capture" — but ordering audit shows that's wrong: Phase 1c (line 580): init_gpu_experience_collector → collector.isv_signals_dev_ptr = 0 (NULL) Phase 2 (line 730): collect_gpu_experiences_slices → bn_tanh_concat_dd_kernel reads isv[406] = NULL+1624 = 0x658 → ILLEGAL_ADDRESS Phase 4 (line 859+): set_isv_signals_ptr (TOO LATE) The error surfaces as "load sp15_dd_state cubin: ILLEGAL_ADDRESS" via sticky-cascade (the OOB happened in the prior kernel; the next CUDA call — dd_state cubin load — surfaces the cascade). Reproduced locally via compute-sanitizer on test_no_hang_single_epoch (RTX 3050 Ti). Sanitizer pinpointed "Invalid __global__ read of size 4 bytes at bn_tanh_concat_dd_kernel +0x4d0 ... Access at 0x658 is out of bounds" — exactly slot 406 * 4. Fix: move the ISV / SP15 control pointer wiring (set_isv_signals_ptr, set_sp15_alpha_warm_count_ptr, set_sp15_plasticity_target, PER buffer's set_isv_signals_ptr + set_sp15_dd_trajectory_per_env_ptr + set_sp15_per_env_dims) into init_gpu_experience_collector BEFORE the collector is moved into self.gpu_experience_collector. This guarantees the FIRST collect_experiences_gpu call (epoch 0, Phase 2) sees non-NULL pointers — required because cudarc's graph capture bakes the arg values into the captured graph at capture time, so subsequent re-wiring has no effect on the captured replay path. The per-epoch re-wiring at lines 855-957 of the outer epoch loop is now redundant (idempotent setters re-applying the same stable pointers) but kept in place per feedback_no_partial_refactor for explicit per-epoch refresh semantics — these underlying pointers are stable for the trainer's lifetime so re-setting is a no-op, and removing the per-epoch call would scatter the wire-up logic across a non-obvious pre-init / per-epoch split. Verification: * 30/30 SP15 phase 1 oracle tests pass under compute-sanitizer memcheck with 0 errors (unchanged baseline) * test_no_hang_single_epoch under sanitizer: SP15 dd_state OOB is GONE; the first OOB now surfaces at compute_expected_q+0x2480 (denoise_target_q_buf stride 12 vs total_actions=13 — a SEPARATE pre-existing bug previously masked by the SP15 OOB; reported but out of scope for this commit per single-atomic-fix discipline). * compute-sanitizer "Access at 0x658" matches the bn_tanh_concat_dd_kernel isv[406] read path; production training on L40S/H100 should now reach the next-layer issue.

jgrusewski	81a9319d84	fix(sp15-wave3b-followup): migrate evaluate_baseline.rs 3 GpuBacktestEvaluator::new sites — Wave 3b missed the example binary ... Wave 3b (4320820ae) added a 6th window_lob_bars parameter to GpuBacktestEvaluator::new and migrated 3 production lib call sites + 6 test call sites, but the lib-only `cargo check -p ml --features cuda` validation didn't catch the 3 example-binary call sites in evaluate_baseline.rs (lines 1344, 1641, 1802). Argo's ensure-binary step compiles all 4 example binaries (hyperopt_baseline_rl, train_baseline_rl, evaluate_baseline, precompute_features), and evaluate_baseline failed with E0061 (wrong number of args). This commit migrates all 3 sites to construct zero-OFI LobBar SoA inline (eval-path lacks per-bar OFI features — same degradation pattern as the PPO hyperopt adapter Wave 3b D4 resolution; OFI-impact term degrades to 0 while commission + half-spread × position still apply).

jgrusewski	c16b3b5a80	feat(sp15-p1.3.b-followup-B): per-(env,t) dd_trajectory + PER sampler — fixes Wave 4.3 uniform-batch limitation ... Phase 1.3.b-followup (5b394f103) landed the main per-env redesign but deferred dd_trajectory + per_insert_pa migration as Followup-B because the contract shape is per-(env, t) buffer [N*L], not per-env tile. This commit: - Reshapes dd_trajectory_decreasing_kernel to per-env grid [n_envs, 1, 1] x [1, 1, 1]; writes dd_trajectory_per_env[env] - Migrates per_insert_pa to per-transition lookup via env_id = (j % (n_envs * lookback)) / lookback; reads dd_trajectory_per_env[env_id] - Allocates two collector-owned per-env tiles (sp15_dd_trajectory_per_env + sp15_dd_trajectory_prev_dd_per_env); deletes the trainer-owned [1] sp15_dd_trajectory_prev_dd scratch + its setter wiring (replaced by unconditional collector ownership, mirrors sp15_dd_state_per_env pattern) - Extends dd_state_reduce_kernel to mean-aggregate per-env trajectory tile -> ISV[DD_TRAJECTORY_DECREASING_INDEX=439] for HEALTH_DIAG diagnostic preservation - Wires per-env tile dev_ptr + (n_envs, lookback) dims into GpuReplayBuffer via new setters (set_sp15_dd_trajectory_per_env_ptr, set_sp15_per_env_dims) called from training_loop - Migrates 4 dd_trajectory + 1 PER oracle tests to per-env contract - Adds NEW behavioral test per_sampler_weights_per_transition_not_uniform_across_batch: n_envs=2 batch with env-0 trajectory=1, env-1 trajectory=0; asserts priorities[env-0 slots]=3.0 and priorities[env-1 slots]=1.0 in the SAME insert batch (Wave 4.3 would produce uniform 3.0 OR uniform 1.0 across all 8 priorities — the test directly fails the old implementation) - Layout fingerprint marker DD_TRAJECTORY_PER_ENV=sp15_phase_1_3_b_followup_B (greenfield checkpoints OK per spec Q1) Fixes the Wave 4.3 PER limitation: ISV[DD_TRAJECTORY_DECREASING_INDEX= 439] was read ONCE per insert call and applied uniformly to ALL n_envs * lookback * 2 transitions in the batch, so the recovery oversample was statistically biased (whichever env wrote ISV[439] most recently determined the boost for ALL inserted transitions). Per-transition lookup fixes this — each transition's weight reflects its own env's recovery context. Atomic per feedback_no_partial_refactor: kernel reshape + 2 collector- owned per-env tiles + trainer struct cleanup + reduction kernel extension + per_insert_pa kernel signature change + 3 new GPU PER replay buffer fields/setters/accessors + per_insert_pa launch site update + collector launch sequence update + state-reset registry rename (1->2 entries) + 2 dispatch arms + training_loop wiring delete/replace + 4 dd_trajectory test migrations + 1 PER test migration + 1 NEW behavioral test + 2 dd_state_reduce callsite null updates + audit doc all in this commit. Closes the per-env DD redesign chain end-to-end. SP15 reward shaping + recovery-curriculum PER oversample now correctly apply per-env context everywhere they're consumed; no more "whichever env wrote last wins" paths. Verified: all dd_state, dd_trajectory, per_sampler, final_reward, plasticity oracle tests green; ml lib HOLDS the Phase 1.3.b-followup baseline (947 pass / 12 fail) on RTX 3050 Ti — no new regressions.

jgrusewski	5b394f1035	feat(sp15-p1.3.b-followup): per-env DD redesign — Path A env-0-canonical → Path B per-env tile + reduction ... Closes the Phase 1.3.b deferred per-env redesign per feedback_no_partial_refactor. Path A (env-0-canonical, commit 132609724) made every downstream consumer read env-0's DD context; production envs each have their own DD trajectory, so when env-3 was at 30% DD and env-0 was at ATH, the model learning from env-3's transitions saw dd_pct=0 and silently skipped the recovery shaping. Path B threads each env's actual DD context through the reward shaping atomically: (1) dd_state_kernel reshape — grid [n_envs, 1, 1], one thread per env, writes 6 scalars per env to a new per-env tile dd_state_per_env [n_envs * 6]. No more ISV scalar writes. (2) NEW dd_state_reduce_kernel — single-block tree-reduce (no atomicAdd; BLOCK=256 with strided initial pass for n_envs up to 32768 on H100). Mean-aggregates per-env tile → 6 scalar ISV slots [401..407) for HEALTH_DIAG diagnostic. Max-aggregates DD_PERSISTENCE → new slot DD_PERSISTENCE_MAX_INDEX=443 for plasticity injection trigger (one shared advantage-head ⇒ global firing ⇒ max-aggregate is the only correct rule). ISV_TOTAL_DIM 443→444; SP15_SLOT_END 443→444; SP15_SLOT_COUNT 46→47. (3) compute_sp15_final_reward_kernel migration — per-(i,t) per-env DD lookup via env_id = (idx % (N*L)) / L. Helpers sp15_dd_asymmetric_reward and sp15_dd_penalty migrated to take dd_pct + dd_current as scalar parameters (the kernel reads from the per-env tile, threads scalars in). On-policy + CF threads at the same (i,t) read the SAME tile entry (one DD trajectory per env, shared across slot kinds). (4) plasticity_injection_kernel migration — persistence read switched from ISV[404] (mean) to ISV[443] (max). One set of advantage weights ⇒ ANY env exceeding the threshold should arm the gate. (5) Per-env tile owned by GpuExperienceCollector (not the trainer) — the collector knows alloc_episodes (= n_envs); the trainer's batch_size is a different quantity. Reset to zero via the sp15_dd_state_per_env registry-arm dispatch. (6) Per-step launch order: dd_state → dd_state_reduce → alpha_split_producer → final_reward, all on the same stream (CUDA serialises producer→consumer without explicit event sync). (7) HEALTH_DIAG semantic shift (documented breaking change): slots 401-406 now report cross-env mean, not env-0 value. For n_envs=1 smoke configs the mean equals env-0's value (bit-stable migration). (8) Layout fingerprint break: added markers DD_PERSISTENCE_MAX=443; ISV_TOTAL_DIM=444; DD_STATE_PER_ENV=sp15_phase_1_3_b_followup. Pre-followup checkpoints will not load (greenfield OK per spec Q1). (9) 6 oracle tests migrated + 1 NEW behavioral test `dd_state_per_env_diverge_independently` — two-env config (env-0 in recovery, env-1 deepening) verifies independent trajectories + mean-aggregate + max-aggregate semantics. Phase 1.3.b-followup-B (separate split): dd_trajectory_decreasing_kernel + per_insert_pa migration is NOT in scope. The current Wave 4.3 reads ISV[439] at insert-batch time (epoch end) — applied uniformly to ALL inserted transitions (a known pre-existing limitation). Proper fix requires per-(env, t) trajectory buffer [N*L] + env_id-aware lookup in per_insert_pa via env_id = (j % (N*L)) / L. That's a different contract change; splitting preserves no-partial-refactor within each migration. Atomic per feedback_no_partial_refactor: all 5 consumers of single-env- canonical DD slots (final_reward kernel + plasticity kernel + HEALTH_DIAG diagnostic + 6 oracle tests + new behavioral test) migrate to per-env tile lookup in this commit; the new DD_PERSISTENCE_MAX ISV slot lands with its sole consumer (plasticity).

jgrusewski	483cef454c	feat(sp15-p3.5.4.c): production caller + OR-gate consumer for plasticity injection — closes 3.5.4 end-to-end ... Wave 4.2 (ef08611d3) landed cuRAND Kaiming-He weight reset as orphan- with-tests-only. Phase 3.5.4.c creates the production caller and the action-selection consumer atomically per spec lines 4346-4448. Production caller in gpu_experience_collector.rs step 4-pre (BEFORE experience_action_select): - fan_in = cfg.adv_h = 128 (CORRECTED from Wave 4.2's audit-doc error claiming 6528 = adv_h × num_atoms; that's total weight count of one branch's projection, not per-unit input dim. Per feedback_trust_code_not_docs the audit-doc error is also fixed inline in this commit.) - n_weights = branch_0_size × num_atoms × adv_h = 4 × 51 × 128 = 26112 (default config). Resets last 10% = 2611 directional advantage-head weights via cuRAND curand_normal × sqrt(2/128) ≈ 0.125 stddev (was wrongly documented as 0.0175). - Branch: w_b0out (directional) only — plasticity is about escaping stuck-in-flat regimes; targeted at directional choice. - Seed: mix_seed(Phase-3.5.4.c-unique base) ^ t per-step deterministic source; same (FOXHUNT_SEED, t) always yields the same Kaiming-He samples per kernel thread. - Trainer exposes target via new pub fn sp15_w_b0out_target() returning (dev_ptr, n_weights, fan_in); collector consumes via new set_sp15_plasticity_target(); training_loop wires the two. OR-gate consumer in experience_action_select: - New kernel arg float plasticity_m_warm threaded into the cooldown-mask code path. - Wave 1.B's cooldown_active = (cooldown_remaining > 0) extended to cooldown_active = (cooldown_remaining > 0) || (plasticity_warm_remaining > 0). - Flat-on-fire-bar detection — option (a), warm ≥ m_warm − 1.5f per the trigger-then-decrement convention. The kernel sees warm = m_warm − 1 on the fire bar; subsequent warm-up bars observe warm ≤ m_warm − 2. New if (plasticity_fire_bar) branch BEFORE the existing else if (cooldown_active) branch — the fire-bar gets DIR_FLAT, subsequent warm bars get DIR_HOLD via the OR-gate cooldown. Two-step recovery semantics: - Bar T (fire): plasticity launches → ISV[436]=1, ISV[438]= m_warm then decrements to m_warm−1. action_select detects fire-bar → dir_idx = DIR_FLAT. - Bars T+1..T+M_warm−1 (warm): action_select OR-gate forces dir_idx = DIR_HOLD. - Bar T+M_warm: warm transitions to 0, OR-gate inactive, normal Thompson/argmax resumes. When the production caller is unwired (test scaffold path): plasticity_m_warm passes 0.0f, the kernel's fire-bar predicate is dead (warm == 0 too), and the OR-gate degenerates to cooldown-only — bit-identical to the pre-3.5.4.c behaviour. Existing 3 SP15 3.5.b/3.5.3.b action_select oracle tests pass unchanged at m_warm = 0.0f. New behavioral oracle test plasticity_fires_force_flat_then_cooldown_ holds verifies the full sequence on RTX 3050 Ti with M_warm = 5 (shrunk from production's 200 for test runtime): bar 0 → DIR_FLAT, bars 1-3 → DIR_HOLD, bar 4 (warm boundary) → DIR_LONG. ISV side- effects (fired flips 0→1 then debounces, warm decrements with underflow guard) verified bar-by-bar. Eval/backtest path passes m_warm = 0.0f because plasticity is a training-only mechanism (during deterministic eval the weights must remain frozen at their checkpoint values). Atomic per feedback_no_partial_refactor: kernel + caller + consumer + trainer plumbing + 4 launcher-call-site updates (1 production collector + 1 eval-path + 2 test scaffolds) + new behavioral test + audit-doc fan_in inline correction + new audit-doc entry all in this commit. No fallback. SP15 Phase 3.5 recovery-dynamics chain is now end-to-end production-wired (3.5.2 + 3.5.3 + 3.5.4 + 3.5.4.c + 3.5.5 + 3.5.5.b all firing).

jgrusewski	19f6cce510	feat(sp15-wave4.3 / 3.5.5.b): PER sampler integration — recovery transitions oversampled ... Phase 3.5.5 (69b8fdb61) landed dd_trajectory_kernel writing ISV[DD_TRAJECTORY_DECREASING_INDEX=439] per-step but DEFERRED the PER sampler integration AND the production launch. Wave 4.3 wires both atomically per feedback_wire_everything_up. Investigation finding — Case B (existing TD-error-driven priority sampler): the GPU PER architecture in crates/ml-dqn/src/gpu_replay_buffer.rs already weights replay by per-transition priority (raw priority + priorities_pa = priority^alpha feeding the prefix-sum sampler). Recovery boost slots in cleanly as a multiplier on priorities[idx] at insert time — no architectural refactor, no new sampling-path machinery. Recovery-oversample formula: effective = base_priority × (1.0 + ISV[440] × ISV[439]) priorities[idx] = effective priorities_pa[idx] = effective^alpha When a transition is in a recovery (DD shrinking from non-trivial DD, ISV[439]=1.0), it lands in the buffer at 1 + ω(2.0) × δ(1.0) = 3.0× the baseline max_priority, then sampled 3.0^0.6 ≈ 1.93× more often than baseline (alpha=0.6 PER convention) until per_update_pa overwrites priority based on TD-error and normal PER takes over. Recovery transitions get amplified gradient signal — the agent learns recovery dynamics over typical "average-DD" Bellman noise. Atomic landings (per feedback_no_partial_refactor): * crates/ml-dqn/src/per_kernels.cu — per_insert_pa kernel signature extended (+priorities, +isv pointers); kernel writes both columns of the (priority, priority^alpha) row pair; nullable ISV ptr falls back to boost_factor=1.0 * crates/ml-dqn/src/gpu_replay_buffer.rs — new isv_signals_dev_ptr field + setter + accessor + priorities_pa_slice accessor; redundant pre-3.5.5.b scatter_insert_f32 broadcast of max_priority REMOVED (now subsumed by per_insert_pa's priorities[idx]=effective store) * crates/ml/src/cuda_pipeline/gpu_experience_collector.rs — new sp15_dd_trajectory_prev_dd_dev_ptr field + setter; per-step launch_sp15_dd_trajectory_decreasing invocation gated on both ISV ptr + prev_dd ptr being non-zero, placed immediately after launch_sp15_dd_state in the env-step loop * crates/ml/src/trainers/dqn/trainer/training_loop.rs — two new wiring blocks for the collector's prev_dd ptr and the replay buffer's ISV ptr, mirroring the existing set_isv_signals_ptr / set_sp15_alpha_warm_count_ptr plumbing * crates/ml/tests/sp15_phase1_oracle_tests.rs — new oracle test per_sampler_weights_recovery_transitions_higher verifying both columns of the priority-buffer write equal exactly the boosted/baseline values (3.0 vs 1.0; 3.0^0.6 vs 1.0^0.6) and the boosted/baseline ratio = 3.0 within 1e-5 — the recovery oversample factor by construction Phase 3.5.5 deferred consumer eliminated per feedback_wire_everything_up. This closes the SP15 Phase 3.5 recovery-dynamics chain (3.5.2 + 3.5.3 + 3.5.4 + 3.5.4.b + 3.5.5 + 3.5.5.b all wired). DD_TRAJECTORY_FLOOR (slot 441) and ISV-driven RECOVERY_OVERSAMPLE_WEIGHT (slot 440) producers remain documented follow-ups per feedback_isv_for_adaptive_bounds — kernel reads from slots rather than literals so consumer migration is a no-op when the producers land. Verified on RTX 3050 Ti (CUDA 12.9, sm_86): * cargo check -p ml-dqn / -p ml --features cuda clean * 3 of 3 dd_trajectory oracle tests still green * 1 of 1 new per_sampler oracle test green (3.0 vs 1.0 priority bias, ratio = 3.000... within 1e-5) * 8 of 8 (1 ignored) gpu_residency replay-buffer + adamw smoke tests green * 4 of 4 PER smoke tests green * Full ml lib suite IMPROVES Wave 4.2 baseline: 947 pass / 12 fail (was 946 pass / 13 fail; the previously-failing test_dqn_checkpoint_round_trip now passes — likely the redundant pre-3.5.5.b scatter_insert_f32 was racing with the immediate per_insert_pa overwrite under particular timing conditions; the merged single-kernel write closes that race) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-07 01:38:13 +02:00
jgrusewski	ef08611d3f	feat(sp15-wave4.2 / 3.5.4.b): cuRAND Kaiming-He weight reset for plasticity injection ... Phase 3.5.4 (e0e0abfb2) landed the trigger + warm-up tracker but deferred the actual weight reset (kernel accepted advantage_head_weights + n_weights but no-op'd via (void) cast). Wave 4.2 lands the real reset. When DD_PERSISTENCE exceeds threshold AND not yet fired this fold, the kernel now resets the last 10% of advantage-head weights to Kaiming-He init: Normal(0, sqrt(2/fan_in)) sampled via cuRAND curand_normal() with per-thread state initialized from a host-passed seed (Option A: per-call curand_init(seed, tid, 0, &state) for full determinism — bit-identical samples for identical (seed, tid) pairs). Single kernel, two phases: 1. Every thread independently re-evaluates fire_now from the same ISV reads (DD_PERSISTENCE / threshold / fired_flag); the trigger condition is a pure function of these reads so all threads converge without cross-block synchronisation. Block 0 / thread 0 also runs the trigger + warm-bars decrement (single-thread ISV write path). 2. If fire_now: each tid < reset_count writes Kaiming-He sample to advantage_head_weights[reset_start + tid]. Per-thread independent write, no atomic, no reduction (feedback_no_atomicadd clean). New launcher params: fan_in (i32), seed (u64). Grid: ((n_weights/10 + 255) / 256).max(1) x [256, 1, 1]. The .max(1) floor ensures block 0 always exists even when n_weights/10 == 0. cuRAND device functions (curand_init, curand_normal) are inlined into the cubin by nvcc from <curand_kernel.h> in the standard CUDA toolkit include path — no host-side cuRAND linker dependency required, no build.rs link change needed. Oracle test plasticity_injection_kernel_resets_last_10pct_kaiming_he verifies: (a) ISV[fired] flipped 0->1, (b) ISV[warm] = m_warm - 1, (c) first 90% bit-identical to 1.0, (d) last 10% all moved off 1.0, (e) sample mean |mean| < 0.05, (f) sample std within +-20% of sqrt(2/fan_in), (g) determinism re-check produces bit-identical samples for identical seed. 3 existing trigger tests migrated to the new launcher signature; the debounced + no-fire variants additionally assert weight-stability (early-out path skips the reset region). Atomic per feedback_no_partial_refactor: kernel + launcher + 4 tests + audit doc + build.rs comment + 2 docstrings land together. Eliminates Phase 3.5.4 deferred consumer per feedback_wire_everything_up (the (void) casts are gone). Action-selection consumer wiring (Phase 3.5.4.c) remains the separate follow-up per the established Phase 3.5.X pattern.

jgrusewski	a54f53e4ed	feat(sp15-wave4.1c): behavioral KL test — dd_pct trunk integration shifts policy distribution ... Closes out Wave 4.1 (Phase 1.5.b consumer migration). Wave 4.1a (a8da1cb9c) landed bn_tanh_concat_dd_kernel that fuses dd_pct into the trunk input; Wave 4.1b (eb9515e41) wired s1_input_dim 102→103 through GRN reshape + 4 forward + 3 backward call sites. Wave 4.1c proves the wiring actually changes the policy: a synthetic GPU forward composing launch_sp15_bn_concat_dd with cublasSgemm_v2 against random Xavier-init weights W[proj_h=4, 103] yields measurably different action distributions when ISV[DD_PCT]=0.0 vs 0.10 — observed mean KL=1.158e-4 (max=3.005e-4) vs threshold 1e-6 (~100× headroom). Why a synthetic projection vs the real GRN trunk: the seeded forward_trunk_for_test helper from Wave 4.1a noted (lines 2304-2319) that exposing the trainer's trunk forward for tests would require either (a) a public surface change on DQNTrainer exposing internal cuBLAS handles + GRN scratch + weights (the trainer's fused_ctx is pub(crate) and only initialised inside the training loop at training_loop.rs:547 — DQNTrainer::new returns with fused_ctx: None), or (b) duplicating the trunk's cuBLAS setup in a test (≥200 lines of buffer plumbing). Both options are architecturally heavier than the test's purpose justifies. Per the spec dispatch ("the test's purpose is 'non-zero KL proves the wire is connected' not 'verifies trained behavior'"), the synthetic single-layer projection is the right scope: it exercises the new column-102 weights on the dd_pct value — exactly the path the real GRN's Linear_a first GEMM takes for w_a_h_s1[:, 102] (the dd_pct column added by Wave 4.1b's reshape). Test contract: - Two passes through launch_sp15_bn_concat_dd + cublasSgemm_v2 differ ONLY in ISV[DD_PCT_INDEX=406] (0.0 at-ATH vs 0.10 in-DD). - Inputs (bn_hidden, states) deterministic; weights deterministic via LCG seed=42 with Xavier-uniform bound = sqrt(6 / (103+4)) ≈ 0.237. - KL > 1e-6 (set 100× below the observed magnitude so a real wiring break fires this test, not silently passing). What this test does NOT verify: the full GRN composition (ELU/GLU/LN/residual) propagating dd_pct through h_s2 + the branch advantage heads. That end-to-end behavior is exercised by the L40S smoke + production training runs. Phase 1.5.b orphan launcher chain fully eliminated per feedback_wire_everything_up: kernel landed (4.1a) → consumer migration (4.1b) → behavioral verification (4.1c) — three atomic commits, the 3a/3b/3c split-pattern matching Wave 3's a/b decomposition. The Wave 4.1a transient orphan window opened in a8da1cb9c → closed in eb9515e41 → behavioral coverage added here. Wave 4.1a's seeded helpers consumed: kl_divergence (used) and minimal_trainer_for_tests (retained but unused — the seeded comment correctly identified that exposing the trunk forward via the trainer surface is non-trivial, so the helper waits for a future cargo-cult test that needs trainer construction without GPU forward, e.g. weight-shape introspection). Touched: crates/ml/tests/sp15_phase1_oracle_tests.rs (+1 module sp15_wave_4_1c_behavioral with 1 ignored test, 2 helper fns, 1 assertion block — purely additive, no kernel or production-code changes), docs/dqn-wire-up-audit.md (Wave 4.1c entry at top of audit doc). Verified: - SQLX_OFFLINE=true cargo check -p ml --features cuda --tests clean (18 pre-existing unrelated warnings, no new warnings). - CUDA_COMPUTE_CAP=86 cargo test -p ml --test sp15_phase1_oracle_tests --features cuda -- --ignored bn_concat dd_pct --nocapture: 2 of 2 oracle tests green (Wave 4.1a bn_tanh_concat_dd_kernel_writes_dd_pct_column + Wave 4.1c dd_pct_trunk_input_shifts_policy_distribution). - cargo test -p ml --features cuda --lib: 947 passed / 12 failed — exactly matches Wave 4.1b baseline (test addition is in the --test integration target, not lib target).

jgrusewski	eb9515e41c	feat(sp15-wave4.1b): consumer migration — s1_input_dim 102→103, GRN w_s1 reshape, 4 forward + 3 backward sites ... Atomic consumer migration that flips production callers of bn_tanh_concat_kernel over to Wave 4.1a's bn_tanh_concat_dd_kernel and bumps s1_input_dim from 102 to 103 across the entire trunk forward + backward path. Eliminates the documented Wave 4.1a transient orphan. Changes: - s1_input_dim formula bump (bn_dim + portfolio_dim → bn_dim + portfolio_dim + 1) at compute_param_sizes, trainer ctor's CublasGemmSet, xavier_init_params_buf, the experience collector's CublasGemmSet, and CublasBackwardSet::new for the backward gemm cache. cuBLAS gemm caches re-key automatically (fresh HashMap). - GRN w_a_h_s1[0] / w_residual_h_s1[4] reshape [shared_h1, 102] → [shared_h1, 103] via compute_param_sizes + xavier_init's fan_dims. Xavier-uniform init covers the new dd_pct column (bounded [0,1] — Xavier's small-magnitude assumption is appropriate; differs from SP14's aux_softmax_diff zero-init which was driven by the bidirectional ±1 range). - bn_concat_dim() accessor +1 (TLOB backward row stride). - 5 concat_dim local-var bumps (1 alloc + 3 forward + 2 backward + 1 in experience collector). - 4 forward-call migrations to launch_sp15_bn_concat_dd: DDQN argmax pass (~27158), online forward (~27467), target forward (~27666), experience collector forward (~3853). Each takes self.isv_signals_dev_ptr; the kernel reads ISV[DD_PCT_INDEX=406] on-device and broadcasts. - 3 GRN backward sites (main, ensemble, CQL) flow through encoder_backward_chain which uses s1_input_dim — bumped automatically. dd_pct column gradient is silently discarded by vsn_d_gated_state_portfolio_pad_kernel (reads [bn_dim..bn_dim+portfolio_dim) only) and bn_tanh_backward_kernel (reads [0..bn_dim) only). Correct: dd_pct sources from ISV bus, no learnable input. - Legacy bn_tanh_concat_kernel field DELETED from trainer struct alongside its loader, tuple-element, destructuring, assignment (5 mechanical sites for the one dead field). Function tuple shrinks 44→43 elements. Kernel symbol stays in the cubin source for SP15 oracle parity tests. - mag_concat / OFI concat audit verdict: DECOUPLED from s1_input_dim. They widen shared_h2, not the trunk INPUT dim. - test_gpu_backtest_evaluator_state_dim_calculation migrated to assert STATE_DIM == 128 (was 96, stale per feedback_trust_code_not_docs). Atomic per feedback_no_partial_refactor: every consumer of s1_input_dim and bn_concat_buf row-stride migrated together. Eliminates Wave 4.1a transient- orphan launcher per feedback_wire_everything_up. Legacy field deleted per feedback_no_legacy_aliases. Tests: cargo check clean (18 pre-existing unrelated warnings). Wave 4.1a oracle parity test (bn_tanh_concat_dd_kernel_writes_dd_pct_column) still passes. ML lib suite went from 945 pass / 14 fail (pre-Wave-4.1b baseline) to 947 pass / 12 fail post-Wave-4.1b — improved by +2 (state_dim_calculation migration + ensemble checkpoint round-trip flake resolved).

jgrusewski	a8da1cb9cf	feat(sp15-wave4.1a): bn_tanh_concat appends dd_pct column from ISV — bottleneck-aware Phase 1.5 consumer migration ... The standalone dd_pct_concat_kernel from Phase 1.5 was bottleneck- incompatible — it operated on raw [B, 128] state, but production trunk consumes [B, s1_input_dim] = [B, 102] post-bottleneck. Wave 4.1a fixes this at the kernel level; Wave 4.1b lands the consumer migration (s1_input_dim 102→103, GRN w_s1 reshape, 3 forward + 3 backward sites). Spec correction (per feedback_trust_code_not_docs): the spec's 'state_dim 48→49' is stale terminology pre-STATE_DIM 48→112→128 evolution. Production s1_input_dim is bottleneck_dim + (STATE_DIM − market_dim) = 16 + (128 − 42) = 102. Wave 4.1b will bump this to 103. NEW bn_tanh_concat_dd_kernel in dqn_utility_kernels.cu: - Fuses dd_pct append into the same launch as bn_tanh + portfolio concat (output shape [B, bn_dim + portfolio_dim + 1]) - Reads isv[DD_PCT_INDEX=406] (set by Wave 1.3.b dd_state_kernel per-step), broadcasts the scalar across batch as the appended last column DELETED standalone dd_pct_concat_kernel.cu + launch_sp15_dd_pct_concat + cubin manifest entry per feedback_no_legacy_aliases (zero production callers — only test consumer; bottleneck-on path is canonical). Test helpers added (used by Wave 4.1c behavioral KL test). Phase 1.5 oracle test migrated to bn_tanh_concat_dd_kernel contract: test name bn_tanh_concat_dd_kernel_writes_dd_pct_column passes on RTX 3050 Ti. Layout fingerprint already covers Phase 1.5 via the existing TRUNK_INPUT_DD_PCT=sp15_phase_1_5; marker — pre-SP15 checkpoints already break. fxcache schema_hash auto-bumps from file content hashes (per task P5T5 Phase F mechanism); no manual schema bump needed. Atomic per feedback_no_partial_refactor for the kernel-signature contract change. Consumer wiring (s1_input_dim propagation, GRN reshape, forward/backward call sites) deferred to Wave 4.1b's atomic commit per the established 3a/3b split precedent — kernel + launcher land first.

jgrusewski	4320820ae2	feat(sp15-wave3b): host-side wire-up — eliminates 5 orphan launchers via GpuBacktestEvaluator constructor signature change ... Second half of the Wave 3 val-cost-streams refactor (3a kernel-side foundation landed at e968f4ded). Atomically migrates the GpuBacktestEvaluator::new contract; 3 call sites + 6 test call sites + 5 WindowMetrics fields + 11 new buffers + launch sequence wiring all in this commit. Constructor signature change: GpuBacktestEvaluator::new gains window_lob_bars: &[Vec<LobBar>] parameter alongside existing window_prices + window_features. Three production call sites migrated atomically: - trainers/dqn/trainer/metrics.rs:651 (val_evaluator construction) - trainers/dqn/trainer/metrics.rs:1166 (extra_eval Dev/Test) - hyperopt/adapters/dqn.rs:1493 (full LobBar with real OFI) - hyperopt/adapters/ppo.rs:1364 (zero-OFI LobBar — PPO lacks per-bar OFI features; cost-net OFI-impact term degrades to 0; commission + half-spread × position still apply) 11 new mapped-pinned buffers on GpuBacktestEvaluator: Input (3): close_prices_buf, half_spread_buf, ofi_scalar_buf Derivation (3): position_history_buf, side_ind_buf, rt_ind_buf Output (5): cost_net_sharpe_buf, baseline_{buyhold,hold_only, momentum,reversion}_sharpe_buf 5 new WindowMetrics fields (host-annualised via × annualization_factor): - sharpe_cost_net (1.2.b cost-net sharpe) - baseline_{buyhold,hold_only,momentum,reversion}_sharpe (1.4.b) Per-window eval flow now: existing fused metrics kernel → 1.1.b sharpe → position_history_derivation (one launch over all windows) → cost_net_sharpe (per-window) → 4 × baseline_* (per-window). commission_per_rt: host-computed constant per D3 resolution, formula config.tx_cost_bps × 0.0001 × config.initial_capital, passed by-value at each baseline + cost_net launcher invocation. Wave 3a kernel signature follow-up: cost_net_sharpe_kernel side_ind / rt_ind switched from unsigned int* → float* so the cost-net kernel chains directly with the f32 streams emitted by position_history_derivation_kernel (no u32→f32 adapter buffer; bit-pun mismatch fixed). cost_net oracle test migrated MappedU32Buffer → MappedF32Buffer accordingly.

jgrusewski	e968f4ded9	feat(sp15-wave3a): kernel-side foundation — baseline output buffers + position_history derivation ... Wave 3a half of the val-cost-streams refactor (3b host-side wire-up follows). Atomically migrates the kernel-side contracts; 5 launchers remain orphan transiently awaiting 3b production callers. Baseline kernels (1.4): - 4 baseline_*_kernel signatures gain 'out: float*' parameter writing per-window [mean, std, raw_sharpe] (matches 1.1.b sharpe_per_bar shape) - ISV writes to slots 409, 410, 412, 416 removed entirely (per-window output is correct for WindowMetrics consumption; ISV-scalar writes were spec scaffolding for a single-fold-aggregate version that 1.4.b's per-window contract supersedes) - 4 ISV slot constants removed from sp15_isv_slots.rs - state_reset_registry: NO entries to remove (verified via grep — the 4 slots never had registry entries / dispatch arms in the first place; they were single-fold-aggregate scalars defaulted at every fold start by the constructor-write that initialises the ISV bus). Task 4 from the dispatch is a no-op; the every_fold_and_soft_reset_entry_has_dispatch_arm regression test continues to pass unchanged. - 4 oracle tests migrated to output-buffer assertion - layout_fingerprint_seed string updated (4 retired entries removed, 4 trunk-shared entries retained; layout-break-class change) New action_decoding_helpers.cuh: - Extracts factored_action_to_dir_idx + factored_action_to_position __device__ helpers (the latter is a higher-level position state- machine helper not previously available) - Mirrors trade_physics.cuh::decode_direction_4b semantics exactly so on-policy and counterfactual paths agree on factored-action meaning - Single source of truth for action→direction→position mapping; consumers #include the header New position_history_derivation_kernel.cu (post-loop derivation for cost_net_sharpe consumer in Wave 3b): - Reads actions_history_buf, reconstructs per-bar position_history (-1/0/+1), side_ind (1.0 on position change), rt_ind (1.0 on transition-to-flat from non-flat) via sequential walk (single block per window, no atomicAdd per feedback_no_atomicadd) - New launcher launch_sp15_position_history_derivation in gpu_dqn_trainer.rs - New cubin manifest entry in build.rs - 1 oracle test covering 8-bar Short→Hold→Long→Hold→Flat→Long→Flat→ Short sequence; expected position/side_ind/rt_ind triples match hand-computed values Atomic per feedback_no_partial_refactor for the ISV-contract change (every consumer of slots 409/410/412/416 migrated in this commit; their consumers were the 4 oracle tests, all migrated). The orphan launcher transient state for the 5 baselines + derivation kernel is explicitly the 3a/3b split point — production callers land in 3b's GpuBacktestEvaluator::new constructor signature change.

jgrusewski	334b496647	feat(sp15-wave2): fused post-SP11 reward-axis composer (layered architecture) ... Closes the deferred-consumer gap left by Phase 3.1 (r_quality_discipline_split_kernel, commit 5d36f3238), Phase 3.3 (dd_penalty_kernel), and Phase 3.5.2 (dd_asymmetric_reward_kernel) — three SP15 reward-axis kernels that landed only as standalone scalar producers awaiting deferred consumer wiring per feedback_no_partial_refactor.md. Wave 2 chooses Option β (layered, composable post-modifier) over Option α (replace SP11 entirely): SP11 B1b stays canonical "trader-quality" composer that writes out_rewards; the SP15 reward-axis composition becomes a fused PER-(i,t) post-modifier read-modify-writing the same buffer in place. This preserves SP11's z-score mag-ratio contract (canary tests untouched) while landing all three deferred SP15 consumers atomically with zero parallel paths. Architecture (Q1-Q4 user resolutions): Q1: SP12 caps stay as state_layout.cuh macros (REWARD_NEG_CAP=-10, REWARD_POS_CAP=+5), NOT lifted to ISV — spec'd constants per the SP12 v3 design, not adaptive bounds. Q2: Both on-policy + CF slots get the same DD-aware shaping. CF reward = w_cf × r_cf (SP11 controller weight already applied) is composed via the same helpers as on-policy. DD context is per-step, not per-action. Q3: New slot_completed_normally[N*L] flag preserves SP11's early-return semantics (data-end at experience_kernels.cu:2142 → reward=0.0; blown-account at :2203 → reward=-10.0). Fused kernel skips slots where flag==0. Q4: alpha_split_producer_kernel OWNS the warm-count increment (per-step scalar producer; the fused kernel has 2*N*L threads and would over-tick by that factor if it owned the increment). Per-step launch sequence in gpu_experience_collector.rs (after Phase 1.3.b's dd_state launch): experience_env_step → alpha_split_producer (reads grad-norm slots 418/419, writes ALPHA_SPLIT slot 417, increments warm-count) → compute_sp15_final_reward (fused per-(i,t) over [N*2*L] slots, applies α-blend → DD asymmetric → DD penalty → SP12 cap, writes back to out_rewards in place). experience_env_step signature change — 2 new output params: r_discipline_out: float* [N*L] — per-step REGRET_EMA mirror, written at end of normal reward composition. slot_completed_normally_out: int* [N*L] — 0 default at entry, set to 1 only on the path that reaches out_rewards[out_off] = reward. 3 deleted kernel files: - r_quality_discipline_split_kernel.cu (composer + producer; replaced by renamed alpha_split_producer_kernel.cu keeping ONLY the producer with the moved warm-count increment). - dd_penalty_kernel.cu (replaced by sp15_dd_penalty __device__ helper). - dd_asymmetric_reward_kernel.cu (replaced by sp15_dd_asymmetric_reward helper). 3 new files: - alpha_split_producer_kernel.cu (per-step scalar producer of α from grad-norm ratio, with warm-count increment moved here per Q4). - sp15_reward_axis_helpers.cuh (4 __device__ inline helpers: sp15_alpha_blend, sp15_dd_asymmetric_reward, sp15_dd_penalty, sp15_apply_sp12_cap). - compute_sp15_final_reward_kernel.cu (fused per-(i,t) parallel over [N*2*L] slots — α-blend + DD-asymmetric + DD-penalty + SP12 cap, skips early-return sentinel slots). 3 deleted launchers + 3 deleted CUBIN statics in gpu_dqn_trainer.rs: - launch_sp15_r_quality_discipline_split (composer scalar variant). - launch_sp15_dd_penalty. - launch_sp15_dd_asymmetric_reward. - SP15_R_QUALITY_DISCIPLINE_SPLIT_CUBIN. - SP15_DD_PENALTY_CUBIN. - SP15_DD_ASYMMETRIC_REWARD_CUBIN. 2 new launchers + 2 new CUBIN statics: - launch_sp15_final_reward + SP15_FINAL_REWARD_CUBIN. - SP15_ALPHA_SPLIT_PRODUCER_CUBIN (the retained launch_sp15_alpha_split_producer now loads this). GpuExperienceCollector: 2 new CudaSlice fields (r_discipline_per_sample, slot_completed_normally_per_sample) + sp15_alpha_warm_count_dev_ptr field + set_sp15_alpha_warm_count_ptr setter + Step 5b launch block. State reset registry — no new entries: r_discipline + slot_completed_normally are per-step ephemeral (defaulted at every kernel entry); cross-fold leakage impossible. Existing Phase 3.1/3.3/ 3.5.2 ISV slot entries cover the rest. 6 new oracle tests in sp15_phase1_oracle_tests.rs::mod gpu drive compute_sp15_final_reward_kernel directly with hand-crafted buffers: - final_reward_alpha_blend_at_cold_start (Stage 1) - final_reward_dd_penalty_above_threshold (Stage 3) - final_reward_dd_asymmetric_gain (Stage 2 + R_GAIN_DD_BOOST diag) - final_reward_dd_asymmetric_loss (Stage 2 asymmetric guard) - final_reward_sp12_cap_clamps_both_directions (Stage 4) - final_reward_skips_early_return_slots (Q3 sentinel preservation) 9 deleted scalar-kernel oracle tests: - r_split_uses_sentinel_alpha_at_cold_start - r_quality_subtracts_explicit_cost - dd_penalty_quadratic_above_threshold + dd_penalty_zero_below_threshold - dd_asymmetric_reward_gain_amplified_by_dd_pct + dd_asymmetric_reward_loss_unchanged + dd_asymmetric_reward_no_op_at_ath (the new fused-kernel tests cover the same behavioral surface end-to-end through the in-place RMW path). Verified: SQLX_OFFLINE=true cargo check -p ml --features cuda clean (18 unrelated warnings); all 29 SP15 phase1 oracle tests pass on RTX 3050 Ti (includes the 6 new fused-kernel tests + 17 retained tests + 6 old); SP11 mag-ratio canary tests still untouched (no canary-test renames or deletions); ml lib suite holds 946 pass / 13 fail = baseline. Hard rules: feedback_no_partial_refactor (3 phases' deferred consumers + 3 deletions + 3 new files + 6 new tests + audit doc all in this commit; no parallel paths, no feature flags), feedback_wire_everything_up (closes 3 SP15 phase orphan launchers atomically), feedback_no_legacy_aliases (deletions land in same commit as replacement; no compatibility shim), feedback_no_atomicadd (fused kernel is per-(i,t) parallel, pure scalar arithmetic), pearl_audit_unboundedness_for_implicit_asymmetry (gain-only DD multiplier + asymmetric NEG/POS caps preserve loss aversion), pearl_symmetric_clamp_audit (SP12 cap is bilateral via fmaxf/fminf even though bounds are intentionally asymmetric per spec), pearl_no_host_branches_in_captured_graph (new launches happen inside collect_experiences_gpu::launch_timestep_loop per-step, OUTSIDE the experience-fwd CUDA Graph capture region — same precedent as Phase 1.3.b's dd_state launch).

jgrusewski	f01a292f6f	feat(sp15-p3.5.b+3.5.3.b): wire hold_floor (inline) + cooldown mask into experience_action_select ... Phase 3.5 (hold_floor_kernel) + Phase 3.5.3 (cooldown_kernel) landed the producer + state machinery; both deferred the action-selection consumer wiring. This task wires both atomically. Architectural decision: hold_floor is now an INLINE __device__ computation inside experience_action_select reading ISV slots 426/427/428/429 directly. The standalone hold_floor_kernel.cu + launch_sp15_hold_floor + HOLD_FLOOR_CUBIN are deleted — launching a kernel to write one f32 just to read it back was unnecessary. ISV slots + state_reset_registry entries remain; only the launch path is removed per feedback_wire_everything_up + feedback_no_legacy_aliases. Entropy source: per-step Shannon entropy of softmax(e_dir) computed inline from the 4 e_dir floats already in registers (Pass 1 of the Thompson direction selector). High entropy = uncertain policy → Hold gets the floor lift; low entropy = confident policy → floor ≈ 0. q_eff_dir scratch preserves e_dir for downstream consumers (out_conviction, out_q_gaps, out_magnitude_conviction) — adding hold_floor there would corrupt the Kelly-cap warmup floor with a meta-confidence mask. cooldown mask: when ISV[COOLDOWN_BARS_REMAINING=435] > 0, action_select hard short-circuits to dir_idx = DIR_HOLD before Pass 2 — sidesteps the temperature-blend numerics where a finite-sentinel-on-non-Hold approach would let pure-Thompson (τ=1) samples dominate the masked direction. Cooldown supersedes hold_floor — when forcing Hold the floor is moot. 3 new oracle tests: - action_select_applies_hold_floor_inline (no cooldown) - action_select_forces_hold_during_cooldown - action_select_no_force_hold_when_cooldown_zero Atomic per feedback_no_partial_refactor: action_select changes + hold_floor_kernel deletion + cubin manifest update + 3 oracle tests + audit doc all in this commit. No parallel paths, no feature flags. Eliminates Phase 3.5 + Phase 3.5.3 deferred consumers. The cooldown_kernel itself remains (it maintains the consecutive_losses streak + decrements COOLDOWN_BARS_REMAINING per bar); only its consumer is now wired. Verified: cargo check -p ml --features cuda clean; ml lib suite holds 946 pass / 13 fail = baseline; all 6 oracle tests pass on RTX 3050 Ti (3 pre-existing cooldown + 3 new action_select).

jgrusewski	d7f60d4dd7	feat(sp15-p1.6.b+1.7.b): wire dev-eval (Q8 final-fold) + test-eval (per-fold) into trainer ... Phase 1.6 (CLI flags + dev_features/holdout_features stash) and Phase 1.7 (set_test_data_from_slices observer + test_features stash) landed the data-flow scaffolding; both deferred the actual eval consumer. This task wires both atomically as parallel evaluator instances: - dev_evaluator: Option<GpuBacktestEvaluator> -- lazy-init after final fold, fires once against Q8 dev_features (when dev_quarters > 0) - test_evaluator: Option<GpuBacktestEvaluator> -- lazy-init per fold, fires inside the fold loop against the WF test slice (when fold.test_end > fold.test_start) Architectural choice: parallel evaluator instances (NOT window-swap on val_evaluator). Window-swap would require invalidating the CUDA graph between val and dev/test runs -- fragile, and a direct violation of pearl_no_host_branches_in_captured_graph. Parallel instances mirror val_evaluator's lazy-init pattern (TLOB sync, ISV signal pointer, training_mode = false toggle). Implementation lives behind a single shared helper `launch_extra_eval` keyed on an `ExtraEvalKind` enum so Dev / Test share TLOB / ISV / config setup verbatim. HEALTH_DIAG additions: HEALTH_DIAG[N]: dev_eval dev_sharpe_net=... dev_calmar=... dev_max_dd=... dev_trades=... HEALTH_DIAG[N]: test_slice fold=K test_sharpe_net=... test_calmar=... test_max_dd=... test_trades=... The *_sharpe_net key uses the fused-metrics-kernel cost-aware Sharpe (post-Phase-1.1.b split -- already includes tx_cost_bps + spread_cost via the env-step PnL feed); when Phase 1.2.b cost-net sharpe lands, the key name is preserved so the aggregator-script contract holds. Atomic per feedback_no_partial_refactor: both eval calls + both evaluator fields + both HEALTH_DIAG lines + audit doc all in this commit. No parallel paths, no feature flags. Dev_eval runs synchronously via evaluate_dqn_graphed (one-shot, no async pipelining benefit since it doesn't fire per-epoch); val path stays async. Sealed Q9 holdout remains untouched -- Phase 4.3 will load Q9 via a separate eval-only entry point (NOT train_walk_forward). The Phase 1.6 debug_assert sealed-slice guard catches accidental future refactors. Verified: cargo check -p ml --features cuda clean; ml lib suite holds 946 pass / 13 fail baseline; the existing Phase 1.7 oracle test set_test_data_from_slices_fires_observer_and_stashes still passes.

jgrusewski	132609724e	feat(sp15-p1.3.b): wire dd_state per-step launch + drop equity-recompute bug + env-0 canonical observable ... Path A of the blocked 1.3.b investigation: fixes two architectural issues atomically and wires the launcher. (1) Bug fix: dd_state_kernel.cu was recomputing new_equity = PS_PREV_EQUITY + pnl_step and writing it back, but experience_env_step already maintains PS_PREV_EQUITY (experience_kernels.cu:3473-3475) — wiring as-is would silently double-accumulate equity every step. Kernel now READS PS_PREV_EQUITY / PS_PEAK_EQUITY only; does not modify them. pnl_step parameter dropped from both kernel and launcher signatures. (2) Per-env shape decision: kernel is single-thread/single-block; production has N envs but DD ISV slots [401..407) are scalars. Picks 'env 0 as canonical observable' — kernel reads pos_state[0 * PS_STRIDE + ...]. Per-env redesign (per-env tiles + reduction kernel) deferred to Phase 1.3.b-followup if L40S smoke shows single-env DD aggregation is insufficient. (3) Wire-up: launch added at gpu_experience_collector.rs step 5b in launch_timestep_loop, immediately after env_step writes PS_PREV_EQUITY, outside the exp-fwd graph capture region (which ends at line ~3829, well before env_step). Atomic per feedback_no_partial_refactor: kernel signature change + oracle test update + launcher call site update all in this commit. Eliminates the Phase 1.3 orphan launcher per feedback_wire_everything_up. Downstream Phase 3.3 / 3.5.2 / 3.5.4 / 3.5.5 readers will receive live DD values when their consumer wiring lands.

jgrusewski	eda1eccb1a	merge(sp15): bring phase2a (LobBar + behavioral test scaffold + 17 tests) into phase1 ... Brings in Phase 2A.1 (LobBar canonical ABI + 4 synthetic market generators), Phase 2A.2 (oracle + harness + pre-commit hook), and Phase 2B (17 #[ignore] behavioral test contracts) so the phase1 honest-numbers branch has access to the LobBar (price, half_spread, ofi) ABI needed for Phase 1.2.b cost-net sharpe consumer wiring. Path 2 of the BLOCKED 1.2.b investigation: the cost-net kernel needs GPU-resident streams (half_spread, ofi, rt_ind, side_ind, position) that do not exist on phase1; Phase 2A.1's LobBar provides the canonical ABI. Conflict resolution: docs/dqn-wire-up-audit.md — both branches prepended entries; merged by keeping all three (Phase 2A.1 from phase2a, Phase 1.6, Phase 1.7 from phase1). Phase 2A.1 entry placed above Phase 1.6 / 1.7 to keep this region's audit ordering consistent (newer-first locally).

jgrusewski	b791bc8f7f	refactor(sp15-p1.1.b): split sharpe out of fused backtest_metrics kernel; wire dedicated launch_sp15_sharpe_per_bar ... Phase 1.1 landed sharpe_per_bar_kernel.cu + launch_sp15_sharpe_per_bar as orphan scaffolding because the val-side sharpe was inline in backtest_metrics_kernel's 8-metric fusion (lines 208-211, 277), not a host-side loop the spec sketch had assumed. This refactor splits sharpe out: - backtest_metrics_kernel computes 7 metrics now (sortino, win_rate, max_dd, calmar, omega, VaR, CVaR; remaining counters unchanged). Output stride drops 14 -> 13; shmem 6 -> 5 reduction arrays. - gpu_backtest_evaluator calls launch_sp15_sharpe_per_bar against the same GPU-resident per-bar returns buffer, once per window (kernel is single-block by design; n_windows is small). - Annualization moves host-side: WindowMetrics.sharpe = raw_sharpe * annualization_factor. Atomic per feedback_no_partial_refactor: kernel split + offset rebase (every metric below sharpe shifted down by 1) + the lone WindowMetrics.sharpe consumer (consume_metrics_after_event) migrated in one commit. No parallel paths. Output value of WindowMetrics.sharpe is preserved (verified to 1e-5 relative error against f64 closed-form via new oracle test unified_sharpe_kernel_equivalence_under_annualization). All existing Phase 1.1 oracle tests still pass; ml lib test suite holds at the 945/13 baseline (no new regressions). Eliminates the Phase 1.1 orphan launcher per feedback_wire_everything_up. Sets up Phase 1.2.b cost-net sharpe to also use launch_sp15_cost_net_sharpe on the cost-net returns buffer (separate task, separate commit).

jgrusewski	69b8fdb61a	feat(sp15-p3.5.5): recovery curriculum — per-step DD_TRAJECTORY_DECREASING proxy ... Per spec §9.2 (3.5.5) post-amendment-2: replaces non-existent episode-level metadata with per-bar signal that fires when dd_pct(t) < dd_pct(t-1) AND dd_pct(t-1) > DD_TRAJECTORY_FLOOR — i.e. transition is part of a recovery from non-trivial DD. PER sampler (Phase 3.5.5.b follow-up) will read this and weight: sampling_weight = base × (1 + RECOVERY_OVERSAMPLE_WEIGHT × signal) so recovery transitions get amplified gradient signal, completing the downward-spiral break-out chain (3.5.2 reward asymmetry → 3.5.3 cooldown gate → 3.5.4 plasticity → 3.5.5 PER recovery curriculum). 3 ISV slots: 439 DD_TRAJECTORY_DECREASING, 440 RECOVERY_OVERSAMPLE_ WEIGHT (2.0 sentinel; ISV-driven from current dd_pct in follow-up), 441 DD_TRAJECTORY_FLOOR (0.02 sentinel; ISV-driven 25th percentile of running dd_pct distribution in Phase 3.5.5.c follow-up per feedback_isv_for_adaptive_bounds). New sp15_dd_trajectory_prev_dd MappedF32Buffer (size 1) tracks prev_dd across kernel calls — mirrors Task 3.5.3 sp15_cooldown_ consecutive_losses non-ISV mapped-pinned scratch pattern. 4 fold-reset registry entries + dispatch arms (3 ISV + 1 scratch). Per established Phase precedent: kernel + launcher land first; PER sampler integration and 25th-percentile floor producer are purely additive follow-ups per feedback_no_partial_refactor. Anchor test 2.10 recovery_after_streak (Phase 2C / Phase 3.5 paired) — fully green via 3.5.2 + 3.5.4 + 3.5.5 combined.

jgrusewski	e0e0abfb28	feat(sp15-p3.5.4): plasticity injection trigger + warm-up tracker (weight-reset deferred) ... Per spec §9.2 (3.5.4) post-amendment-2 fix. TWO-STEP recovery: 1. Fire when DD_PERSISTENCE > PLASTICITY_PERSISTENCE_THRESHOLD AND PLASTICITY_FIRED_THIS_FOLD == 0 → set fired flag, set warm-bars counter to M_warm (default 200). [DEFERRED: reset last 10% of advantage-head weights to Kaiming-He init via cuRAND.] 2. Per-bar warm-bars decrement; action-selection layer (consumer wiring follow-up) reads max(COOLDOWN_BARS_REMAINING, PLASTICITY_WARM_BARS_ REMAINING) and forces Hold while > 0. Weight-reset DEFERRED to Phase 3.5.4.b — kernel signature plumbed (advantage_head_weights + n_weights) but no-op via (void) cast. Documented in audit doc. 3 ISV slots: 436 PLASTICITY_FIRED_THIS_FOLD (debounce flag, resets at fold boundary to re-arm next fold), 437 PLASTICITY_PERSISTENCE_THRESHOLD (initial 100.0 sentinel; ISV-tracked from running mean of dd_persistence in follow-up), 438 PLASTICITY_WARM_BARS_REMAINING (counter, OR-gates with cooldown). 3 fold-reset registry entries + dispatch arms. Three GPU oracle tests pass: fires-when-persistence-exceeds-threshold (warm_bars [198, 200] post-fire-and-decrement), debounced-within-fold (no re-fire when fired=1; warm decrements 50→49), no-fire-below-threshold. Anchor test 2.22 plasticity_cooldown_interlock (Phase 2C / Phase 3.5 paired) — green via 3.5.4.b follow-up + action-selection consumer wiring.

jgrusewski	649128e739	feat(sp15-p3.5.3): cooldown gate — K=5 force Hold for M=20 bars (initial sentinels) ... Per spec §9.2 (3.5.3). After K consecutive losing trades, force Hold for M bars. Counter at COOLDOWN_BARS_REMAINING (slot 435) part of state — model can reason about it. Initial K=5, M=20 hardcoded sentinels. ISV-driven K via MEDIAN_STREAK_ LENGTH (slot 442) producer using two-heap median tracking is documented Phase 3.5.3 follow-up. ISV-driven M from vol_normalizer time-to-mean- reversion is also follow-up. 4 ISV slots: 433 K_THRESHOLD, 434 M_BARS, 435 BARS_REMAINING, 442 MEDIAN_STREAK_LENGTH. New sp15_cooldown_consecutive_losses MappedF32Buffer tracks streak counter persistent across kernel calls. 5 fold-reset registry entries + dispatch arms (4 ISV slots + scratch buffer reset). Per spec post-amendment-2 fix: streak counter only updates on trade-close events; per-bar non-close calls just decrement the cooldown counter. The trigger gate fires only when a trade-close lands during an inactive cooldown — re-arming mid-cooldown would extend the gate every closed trade during the freeze, which is not the spec. Per established Phase precedent: kernel + launcher land first; action- selection wiring (force Hold while cooldown_remaining > 0) deferred to follow-up commit per feedback_no_partial_refactor. Anchor test 2.12 cooldown_engagement (Phase 2C / Phase 3.5 paired) — green via this commit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-06 17:14:53 +02:00
jgrusewski	aa91ce4d82	feat(sp15-p3.5.2): asymmetric reward under DD — gain × (1 + λ × dd_pct), pre-SP12-cap ... Per spec §9.2 (3.5.2). For gains: r_adjusted = r × (1 + λ × dd_pct). For losses: unchanged. Multiplier applies BEFORE SP12 NEG/POS cap clamp; saturating the cap for big recovery trades is behaviorally correct per spec (encourages frequent small recoveries). 3 ISV slots: 430 DD_ASYMMETRY_LAMBDA (initial 0.5; ISV-tracked from running DD variance via DD_DIST_VAR is follow-up), 431 R_GAIN_DD_BOOST (diagnostic — most recent boost), 432 DD_DIST_VAR (running variance, producer follow-up). 3 fold-reset registry entries + dispatch arms. Per established Phase precedent: kernel + launcher land first; reward composer site (apply multiplier BEFORE SP12 cap) deferred to follow-up commit per feedback_no_partial_refactor.

Hold becomes uncertainty expression, not distributional default. α (HOLD_FLOOR_ALPHA slot 426) initial 0.5 sentinel — producer kernel updating from rolling 95th percentile of |Q_dir| (NOT running max — outlier-ratchet vulnerable per spec second-review #6) is documented Phase 3.5 follow-up. k (HOLD_FLOOR_K slot 427) initial 10.0 — producer from running variance of entropy is follow-up. ε₀ (HOLD_FLOOR_EPS0 slot 428) initial 1.0 — producer from 75th percentile of entropy distribution (ENTROPY_DIST_REF slot 429) is follow-up. 4 fold-reset registry entries + dispatch arms. Per established Phase precedent: kernel + launcher land first; action- selection wiring (add hold_floor to Q_hold pre-argmax/Thompson) deferred to follow-up commit per feedback_no_partial_refactor.

EMA tracked at REGRET_EMA (slot 423) with first-observation bootstrap (per pearl_first_observation_bootstrap) + simple exponential decay (α=0.05; Wiener-α adaptive swap is a documented follow-up). r_discipline_per_bar = -LAMBDA_REGRET × REGRET_EMA composed at the reward-split site in the follow-up consumer commit per feedback_no_partial_refactor. 3 ISV slots: 423 REGRET_EMA, 424 LAMBDA_REGRET (initial 1.0), 425 REGRET_GRAD_NORM. 3 fold-reset registry entries + dispatch arms. Anchor test 2.6 regime_silences (Phase 2B contract) — green via 3.4 + 3.5 combined. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-06 16:02:59 +02:00

Per spec §8.2 (3.3). penalty = λ_dd × max(0, dd_current − dd_threshold)² Asymmetric: zero below threshold, quadratic growth above. Encodes loss aversion per pearl_audit_unboundedness_for_implicit_asymmetry. 3 ISV slots: 420 LAMBDA_DD (initial 1.0; ISV-tracked from grad-balance in follow-up), 421 DD_THRESHOLD (initial 0.05 = 5% drawdown trigger), 422 DD_PENALTY_GRAD_NORM (initial 0.0). 3 fold-reset registry entries + dispatch arms. Per established Phase precedent: kernel + launcher land first; reward composition site (subtract penalty from r_total) deferred to follow-up commit per feedback_no_partial_refactor. Anchor test 2.5 drawdown_de_risks (Phase 2C / Phase 3.5 paired) — green via Phase 3.5 mechanisms; this commit lands the penalty primitive.

jgrusewski	1eac41d644	feat(sp15-p3.2): explicit cost in r_quality on trade-close events ... Per spec §8.2 (3.2). Extends the Phase 3.1 composer kernel `r_quality_discipline_split_kernel` with two new args (`float cost_t`, `unsigned int trade_close_indicator`) and subtracts `cost_t * (float)trade_close_indicator` from `r_quality` BEFORE the α blend. Same `cost_t` scalar shape as the Phase 1.2 cost_net_sharpe accumulator (commission + per-side spread + OFI-impact); the gate `trade_close_indicator=1` on round-trip-close bars (rt_ind=1) and 0 otherwise so non-close bars receive a structural no-op identical to the pre-Phase-3.2 behaviour. Model SEES the bill in the gradient signal during training, not just in eval-time metrics. Approach: kernel-signature-extension (NOT wrapper-kernel). The only existing call site in the tree is the Phase 3.1 oracle test (`training_loop.rs` has dispatch-arm reset wiring but does NOT yet invoke the launcher per the Phase 3.1 commit's deferred-consumer note), so the cascade is bounded to that single test — extending the existing kernel is cleaner than a parallel wrapper that would have to be retired the moment the Phase 3.1 deferred consumer migration lands. Anchor test 2.4 cost_sensitivity (Phase 2B contract) — green via this commit + Phase 3.1 split structure (already landed in 2d226e6e7). Per established Phase precedent: kernel/launcher signature change + existing-test migration land atomically per feedback_no_partial_refactor; production reward-composition wire-up that feeds real `cost_t` from cost_net_sharpe is the same deferred follow-up Phase 3.1 declared (no new debt added — both share one follow-up commit). cargo check -p ml --features cuda: clean (18 pre-existing warnings). cargo test -p ml --test sp15_phase1_oracle_tests --features cuda -- --ignored r_quality_subtracts_explicit_cost: 1 passed. cargo test -p ml --test sp15_phase1_oracle_tests --features cuda -- --ignored r_split_uses_sentinel_alpha_at_cold_start: 1 passed (Phase 3.1 sentinel test post-migration). cargo test -p ml --features cuda: 946 passed / 13 failed (same 13 failures as parent 2d226e6e7; zero introduced).

jgrusewski	2d226e6e76	feat(sp15-p3.1): r_quality + r_discipline split with ISV-driven α + sentinel cold-start ... Per spec §8.2 (3.1) post-amendment-2 fix: ALPHA_SPLIT slot initialized DIRECTLY to 0.5 in trainer constructor. Formula α = grad_norm_q / (grad_norm_q + grad_norm_d + ε) takes over only after BOTH grad-norm EMAs accumulate ≥ N_WARM=100 non-zero observations. Two kernels in r_quality_discipline_split_kernel.cu (single cubin per established 1:1-source-to-cubin pattern with multiple kernels): - r_quality_discipline_split_kernel: per-step composition + warm count - alpha_split_producer_kernel: per-step ALPHA_SPLIT update from grad ratio (gated on warm count to prevent premature formula activation) 3 ISV slots (417 ALPHA_SPLIT, 418 GRAD_NORM_QUALITY, 419 GRAD_NORM_DISCIPLINE) + sp15_alpha_warm_count [1] mapped-pinned scratch buffer on the trainer struct. 4 fold-reset registry entries + dispatch arms (one for the non-ISV warm-count buffer mirrors the sp11_novelty_hash host_slice_mut pattern). Per established Phase precedent: kernels + launchers land first; consumer migration (per-step launches in training_loop.rs reward composition site) deferred to a follow-up commit per feedback_no_partial_refactor. Anchor tests: 2.4 cost_sensitivity + 2.6 regime_silences (Phase 2B contracts) — green via Phase 3.4 regret + 3.2 cost; this commit lands the split structure they depend on.

jgrusewski	7e63f83bf0	test(sp15-p2b): 17 behavioral tests (Group 1 + Group 2) as #[ignore] contracts ... Per spec §7.3 + plan v2 Phase 2B differential table. Each test documents its behavioral contract and its enabling phase. Tests are #[ignore]'d so the pre-commit-hook-gated suite does not fail; per-test #[ignore] is removed by the commit that lands its enabling phase. Group 1 trading behavior (7 tests): 2.1 flat_holds, 2.2 trend_directional, 2.3 mean_revert_reverses, 2.4 cost_sensitivity, 2.6 regime_silences, 2.7 stop_discipline, 2.18 action_latency. Group 2 state/arch grounding (10 tests): 2.8 hold_vs_flat_semantics, 2.9 eval_fold_isolation, 2.13 eval_train_consistency, 2.14 magnitude_uses_ all_buckets, 2.15 fold_transition_stability, 2.16 q_value_bounded, 2.17 gradient_flow_to_all_heads, 2.19 kelly_calibration, 2.20 state_input_ grounding, 2.21 egf_gate_opens (re-export hook for sp14_oracle_tests.rs). Group 3 (Phase 2C — 5 tests) lands paired with Phase 3.5 commits. Harness invocations use trainer = () placeholder; Phase 2B.b extends BehavioralResult/harness with per-bar actions, position-state inspection, forced-action stepping, and per-head grad-norm snapshots.

jgrusewski	ef373c34d7	feat(sp15-p1.7): consume the abandoned walk-forward test slice (stash + observer; eval invocation deferred) ... Per spec §6.7. The walk-forward generator emits `test_start..test_end` per fold but the trainer at `mod.rs:1294` only consumed train+val — the 12.5% test slice was silently dropped, the model was never measured on held-out data the train/val pipeline didn't see. This commit lands the foundation: `set_test_data_from_slices` stashes the per-fold range immediately after `set_val_data_from_slices`, gated on `fold.test_end > fold.test_start` for defensively-empty slices. A `set_test_data_observer` hook lets unit tests verify the wiring without spinning up a full GPU eval pipeline. The actual `evaluate_dqn_graphed` invocation against the stashed slice plus the per-fold `HEALTH_DIAG test_slice fold=K test_sharpe_net=...` emit is deferred to a follow-up commit per `feedback_no_partial_refactor`. Wiring it through requires either standing up a second `GpuBacktestEvaluator` instance (parallel to the val one at `metrics.rs:550`) or refactoring the existing val evaluator to swap window data between val and test eval — the val evaluator's lazy-init path is fundamentally tied to the window passed at construction. Plus TLOB weight sync, ISV signal wiring, and a `training_mode` toggle (no such field exists yet on `DQNTrainer`). This deferral matches the Phase 1.5 (kernel + launcher first, trunk consumer follow-up) and Phase 1.6 (stash dev/holdout slices, eval consumer follow-up) precedents on this branch. The stash + observer surface is the analogous foundation; the L40S smoke once Task 1.7.b lands will surface the per-fold `test_sharpe_net` HEALTH_DIAG line as the canonical end-to-end verifier. New oracle test `set_test_data_from_slices_fires_observer_and_stashes` in `sp15_phase1_oracle_tests.rs` constructs a real trainer (sync init, no GPU forward), registers an observer, exercises the API with a synthetic [5000..6000) range, asserts the observer fires once with the right bounds. Passes locally on RTX 3050 Ti. `docs/dqn-wire-up-audit.md` extended with a Phase 1.7 entry documenting what landed, what's deferred, the wire-up locations, and the rationale.

jgrusewski	ce019c72d2	feat(sp15-p1.6): --holdout-quarters + --dev-quarters CLI flags + sealed Q1-Q7/Q8/Q9 split ... Per spec §6.6 / Q6 train/dev/test split (defaults Q1-Q7 train, Q8 dev, Q9 sealed final test): - DQNHyperparameters: holdout_quarters + dev_quarters (default 1+1) - crates/ml/examples/train_baseline_rl.rs: --holdout-quarters / --dev-quarters CLI flags forwarded to hyperparams (this is the actual training binary; bin/fxt/src/commands/train.rs is a gRPC client and services/ml_training_service/src/main.rs accepts training params via proto not CLI — see audit doc note). - DQNTrainer::train_walk_forward slices training_data BEFORE fold generation; folds run on Q1..Q(9 - holdout - dev) only. - DQNTrainer struct: dev_features/dev_targets/holdout_features/ holdout_targets fields stash trailing slices for end-of-training dev eval and the Phase 4.3 separate eval-only workflow. - debug_assert sealed-slice guard catches future refactors that re-introduce holdout into the training path. Per established Phase 1 precedent (1.1-1.5: kernel/state lands first, consumer wiring deferred to follow-up commit per feedback_no_partial_refactor): CLI plumbing + slicing + dev/holdout storage land in this commit. The post-final-fold dev evaluation call (consumer of dev_features) is deferred to a follow-up commit and will mirror Task 1.7's evaluate_dqn_graphed integration pattern. Phase 4.3 argo-eval-final.sh is the sole legitimate consumer of holdout_features (separate eval-only workflow that does NOT call train_walk_forward). cargo check -p ml --features cuda --example train_baseline_rl: clean cargo check -p fxt: clean (no fxt changes needed; gRPC client only) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-06 14:39:37 +02:00
jgrusewski	5309d4bee5	feat(sp15-p1.5): dd_pct foundational state input concat kernel — LAYOUT FINGERPRINT BREAK ... LAYOUT FINGERPRINT BREAK: pre-SP15 checkpoints WILL NOT LOAD after this commit. Greenfield OK per spec Q1. Per spec §6.5: dd_pct (slot 406, written by Task 1.3 dd_state_kernel) gets concatenated to the trunk forward input as the last dim. Eval-time policy SEES drawdown context on every forward pass; Phase 3 teachings can condition on dd_pct directly via state, not just reward modulation. New kernel `dd_pct_concat_kernel.cu` produces a [B, state_dim_padded + 1] buffer whose leading state_dim_padded columns equal the input states_buf and whose +1 last column equals isv[DD_PCT_INDEX=406] broadcast across batch. Pure scatter-copy (no atomicAdd per feedback_no_atomicadd). layout_fingerprint_seed extended with 'TRUNK_INPUT_DD_PCT=sp15_phase_1_5' marker — FNV1a hash changes; old checkpoints fail to load with the existing layout-mismatch error path (same fail-fast that fired on the SP4 / SP14 layout breaks). Phase 1.5 lands kernel + launcher + layout fingerprint marker + GPU oracle test only. Trunk consumer migration (re-pointing forward_online to consume the concat buffer + bumping s1_input_dim from 48 → 49 + propagating through GRN encoder, VSN gate input, bottleneck path, and backward dx scratch) is deferred to a follow-up atomic commit per feedback_no_partial_refactor — matches the established Phase 1.1-1.4 precedent (kernels + launchers verify in isolation first; consumer migration is a load-bearing change touching the GRN encoder, VSN partition boundaries, fxcache schema, and backward gradient flow). GPU oracle test `dd_pct_concat_kernel_writes_last_column` validates B=4, raw state_dim=48, state_dim_padded=128: leading 128 columns of each output row match the input states (including pad zeros), and the 129th column equals isv[DD_PCT_INDEX]=0.42 broadcast across all 4 rows. Test passes on local RTX 3050 Ti (sm_86) in 1.62s. cargo test -p ml --lib --features cuda: 945 passed / 14 failed — same 14 failures pre-existing on the parent commit `c6fd4b4b2` (Task 1.4 partial baseline); zero introduced by this commit. Per spec §6.5 step 7 (trunk-grounding behavioral test): Phase 4 L40S smoke verifies dd_pct propagation at production scale via the existing layout-fingerprint-mismatch fail-fast on cold-start of any pre-SP15 checkpoint. The follow-up Phase 1.5.b commit that lands the consumer migration adds the explicit trunk-grounding KL test alongside the forward_online wiring. Touched: - crates/ml/src/cuda_pipeline/dd_pct_concat_kernel.cu (new) - crates/ml/build.rs (+1 cubin manifest entry) - crates/ml/src/cuda_pipeline/gpu_dqn_trainer.rs (+SP15_DD_PCT_CONCAT_CUBIN + launch_sp15_dd_pct_concat + TRUNK_INPUT_DD_PCT layout fingerprint marker) - crates/ml/tests/sp15_phase1_oracle_tests.rs (+1 GPU oracle test) - docs/dqn-wire-up-audit.md (+1 Phase 1.5 entry) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-06 14:31:16 +02:00

Pure-CUDA kernels in baseline_kernels.cu — single cubin, 4 extern "C" __global__ functions sharing a templated compute_baseline_sharpe helper. Trunk-shared baselines (random_dir_kelly slot 411, aux_only slot 413, mag_quarter_fixed slot 414, trail_only slot 415) deferred to Task 1.4.b follow-up — they need partial-policy-forward access from the main eval pass. ISV slots written: 409 (buyhold), 410 (hold_only), 412 (naive_momentum), 416 (naive_reversion). Slots 411/413/414/415 stay at sentinel 0.0 until follow-up commit. Per established Phase 1 precedent: kernels + launchers land first; per-eval-pass launches + HEALTH_DIAG baseline_deltas emit deferred to follow-up commit per feedback_no_partial_refactor.

jgrusewski	9e84602486	feat(sp15-p1.3): drawdown state kernel — DD_CURRENT/MAX/RECOVERY/PERSISTENCE/CALMAR/PCT ... Per spec §6.3. Per-step kernel reads PS_PEAK_EQUITY (slot 7) and PS_PREV_EQUITY (slot 9) from existing position state buffer (no new equity slot needed). Writes 6 ISV slots (401-406). Calmar uses max(dd_max, 1e-4) floor — eliminates the saturation-at-100 artifact seen in train-dd4xl HEALTH_DIAG. 6 fold-reset registry entries + dispatch arms. 5 sentinel-0 stateful outputs; calmar uses sentinel 1e-4 (same value as the kernel's floor) so cold-start division uses the floor rather than ±inf. Atomic split per feedback_no_partial_refactor.md (mirrors Task 1.1 + 1.2 precedent): kernel + launcher + registry land here; per-step production wire-up + HEALTH_DIAG composer deferred to a follow-up commit. Test 1.3 oracle on 6-step synthetic equity curve passes locally on RTX 3050 Ti (sm_86) in 1.61s. cargo test -p ml --lib --features cuda: 946 passed / 13 failed — same 13 pre-existing failures as Task 1.2 baseline (a92ff28a9); zero introduced.

Initial λ=2.0e-4 in ISV[OFI_IMPACT_LAMBDA_INDEX=407] as Invariant-1 anchor (constructor-write + FoldReset rewrite per feedback_isv_for_adaptive_bounds); per-fold ISV refit may overwrite in later phases. Mean cost-per-bar emitted to ISV[COST_PER_BAR_AVG_INDEX=408] (stateful kernel output; FoldReset sentinel 0 + Pearl A first-observation bootstrap). Same kernel reads LobBar fields from synthetic markets (Phase 2A) and real fxcache LOB (prod) — dev/prod parity per Q3. Phase 1.2 lands kernel + launcher + anchor seed + 2 registry entries + 2 dispatch arms only; consumer migration deferred to a follow-up commit per feedback_no_partial_refactor (mirrors Phase 1.1 atomic pattern). Oracle test cost_net_sharpe_round_trip_charges_full_spread validates single round-trip cost = 2.00 / 10 bars = 0.20/bar with mean_pnl_net = 0.80 on 1.69s RTX 3050 Ti (sm_86).

jgrusewski	c0fc28e455	fix(sp14): delete warmup_gate — let variance-driven k_aux/k_q handle warmup (ISV-driven) ... Per `feedback_isv_for_adaptive_bounds`, the hardcoded `warmup_gate = (fold_step_counter / WARMUP_STEPS_FALLBACK).min(1.0)` ramp violated the rule: adaptive bounds in ISV, never hardcoded constants. The variance-driven k_aux/k_q sigmoid steepness already provides warmup behavior intrinsically: - High variance (cold-start, EMAs still moving) → k → K_MIN → flat sigmoid → gate ≈ 0.5 regardless of input. That IS the warmup. - Low variance (settled) → k → K_BASE → sharp sigmoid → gates respond correctly to driver signals. Adding a separate hardcoded step-counter multiplier on top was double-counting + tuning-driven (the 1000-step threshold had no principled basis). Removed entirely. Removed (per `feedback_no_partial_refactor`, all atomically): - `WARMUP_STEPS_FALLBACK` constant in `sp14_isv_slots.rs` - `warmup_gate: f32` parameter in `alpha_grad_compute_kernel.cu` - `gate1 * gate2 * warmup_gate` → `gate1 * gate2` in kernel - `warmup_gate` arg from `launch_sp14_alpha_grad_compute` - `fold_step_counter: usize` field on the trainer struct - `fold_step_counter = 0` reset in `reset_for_fold` - `fold_step_counter` init in trainer constructor - `let warmup_gate: f32 = 1.0;` and `.arg(&warmup_gate)` from B.4 oracle tests (4 launches: 2 in alpha_grad_schmitt_hysteresis, 20 in alpha_grad_adaptive_beta loop) Build: clean, 18 warnings (pre-existing baseline). Tests: cargo test --no-run on sp14_oracle_tests succeeds. Net result: EGF gate's warmup behavior now lives entirely in the variance-driven k_aux/k_q sigmoid steepness controller (ISV slots 388/var_aux, 389/var_q). No hardcoded step counter. Honors `feedback_isv_for_adaptive_bounds` and `pearl_controller_anchors_isv_driven`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-05 22:07:55 +02:00
jgrusewski	60ad42676e	fix(sp14): bump ISV_TOTAL_DIM 383 → 396 to cover SP14 EGF slots ... ROOT CAUSE of L1+L2 from Smoke A2-B: the ISV bus was sized for top of SP13 (ISV_TOTAL_DIM=383) but B.1 allocated SP14 slots at 383-395. Every SP14 read/write was OUT-OF-BOUNDS memory access. That's why: - gate1 (slot 391) read as 0 always (OOB zero-init memory) - post_open_min (slot 394) accumulated garbage values 9.5 → 28 → 46 - α_smoothed/α_raw values appeared to work but were undefined behavior SP4/SP5 had a regression test (`all_sp4/5_slots_fit_within_isv_total_dim`) that catches this exact failure mode at unit-test time. SP14 was missing it — that gap let the bug ship across all 16 commits without being caught. Changes: - ISV_TOTAL_DIM: 383 → 396 (covers SP14 slots 383-395) - layout_fingerprint_seed: extended with SP14 slot names + new ISV_TOTAL_DIM=396 marker (forces fingerprint hash bump per Invariant 8 — old checkpoints invalidated correctly) - sp14_isv_slots.rs: 2 regression tests (mirror SP4/SP5 patterns) Both tests pass. After this fix, SP14 EGF kernels will read/write the correct slots; gate1 should actually flip open when aux_dir_acc crosses target+0.03; gradient_hack_detect post_open_min stays bounded in [0, 1] as designed. NOT yet addressed (separate follow-up): - warmup_gate hardcoded WARMUP_STEPS_FALLBACK=1000 violates feedback_isv_for_adaptive_bounds. Should be ISV-signal-driven OR removed entirely (k_aux/k_q already provide variance-driven warmup). Redesign post-re-smoke once bus-size fix is verified.

jgrusewski	e41dbb7d8a	diag(sp14 B.12): per-epoch pearl_egf_diag HEALTH_DIAG emit ... Adds a new HEALTH_DIAG[{epoch}]: pearl_egf_diag line immediately after the aux_moe block in the per-epoch metrics section of training_loop.rs. Reads all 13 SP14 ISV slots [383..396) — α_smoothed, α_raw, β, k_aux, k_q, var_aux, var_q, var_α, q_dis_short, q_dis_long, gate1 state, post_open_min, lockout — via the established read_isv_signal_at pattern, giving forensic visibility into EGF pearl state each epoch. gate1/gate2 sigmoid outputs are intentionally omitted: recomputing them host-side would violate feedback_no_cpu_compute_strict; the sigmoid inputs are sufficient for a reader to infer the output values. docs/isv-slots.md updated (Invariant 7): records B.12 HEALTH_DIAG wire-up.

jgrusewski	857722e774	feat(sp14): B.11 — orchestrator wire-up for 3 EGF producer kernels + var_aux gap closure ... Per-step launches (in graph capture order): 1. Forward (existing) 2. Action select (existing) → q_dir_logits available 3. launch_sp14_q_disagreement_update → ISV[383, 384, 389] 4. launch_sp14_alpha_grad_compute → ISV[385..395] (consumes q_disagreement) 5. Backward (existing) — wire-col scale at B.10 reads ISV[393] Per-epoch launch (end of epoch): 6. launch_sp14_gradient_hack_detect → circuit breaker α_short=0.3, α_long=0.05, α_var=0.05 per spec; warmup_gate derived from steps_in_fold / WARMUP_STEPS_FALLBACK. Var_aux producer gap closed (option C from B.4): alpha_grad_compute_kernel now also writes ISV[VAR_AUX_INDEX=388] via Welford EMA against (aux_dir_acc_short - aux_dir_acc_long). Adaptive k_aux is now functional (was degenerate at K_BASE_AUX=20.0 constant pre-B.11). Closes the "adaptive_k_aux currently degenerate" concern flagged in B.4 commit. After this commit, the EGF pearl is FULLY ACTIVE end-to-end: - Forward: aux signal feeds direction Q-head input (B.8/B.9) - Backward: wire-col gradient gated by α_grad_smoothed (B.10) - Producers: α_grad computed every step from real driver signals (B.11) - Pre-B.11 force-closed gate (sentinel 0.0) → post-B.11 responsive gate Build clean: 18 warnings pre-existing baseline, 0 new. Tests: 4/4 P0b aux_w tests pass (no regression). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-05 21:11:26 +02:00
