chore(sp18): refresh audit fingerprint after Phase 4 docstring update
Off-by-one count drift in the td_lambda_kernel launch-sites bucket (19→20) from a single additional reference in sp18_td_lambda_q_next_oracle_tests.rs's docstring (the docstring now mentions td_lambda_kernel one extra time per the T_SKEL.3 atomic-refactor guard test). Pure documentation update; no source-code change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

feat(sp18 v2 P4.T1+T2): B-leg next_states hoist + compute_q_next_target_bootstrap skeleton (additive dead code)
Phase 4 lands the additive infrastructure for the B-leg target-Q DDQN
bootstrap that Phase 5 will swap into td_lambda_kernel's q_next argument
at gpu_experience_collector.rs:~4313 (post-Task-4.1 hoist).
Tasks landed:
- **Task 4.1**: build_next_states_f32 invocation hoisted to BEFORE
the TD(λ) launch block. Pure ordering change — verified via the
SP18 audit grep flagging 0 post-TD(λ) consumers of next_states.
- **Task 4.2**: compute_q_next_target_bootstrap skeleton method on
GpuExperienceCollector with full plan-aligned signature
(next_states, target_params_ptr, online_params_ptr, batch_size →
Result<CudaSlice<f32>, MLError>). Body is a hard-error early-return
per feedback_no_stubs — no production caller in Phase 4 (the
caller is wired by Phase 5 Task 5.1, replacing the self-bootstrap
clone). Returning Err satisfies Invariant 9 (no deferred-work
markers); any accidental pre-Phase-5 call hard-errors with a
clear pointer to the open sub-tasks.
Tasks 4.3 (online forward + DDQN per-branch argmax), 4.4 (target
forward + compute_expected_q gather), 4.5 (replace error early-return
with full implementation + GPU oracle test gates) are deferred to a
follow-up subagent dispatch per their plan-defined per-task TDD cycle
scope. Each requires substantial new infrastructure on the collector
(target-net trunk forward chain duplicating gpu_dqn_trainer.rs Pass 2's
VSN+BN+OFI+trunk+branch-head sequence).
Tests:
- crates/ml/tests/sp18_td_lambda_q_next_oracle_tests.rs (NEW):
3 introspection tests (no GPU required):
* compute_q_next_target_bootstrap_method_exists
* next_states_built_before_td_lambda (Task 4.1 ordering invariant)
* td_lambda_still_consumes_self_bootstrap_q_next_in_phase4
(Phase 4→Phase 5 atomic-refactor guard)
Atomic-refactor invariant (HARD — feedback_no_partial_refactor):
NO L40S DISPATCH between this Phase 4 close-out commit and the
Phase 5 Task 5.1 commit that replaces the q_next clone with
self.compute_q_next_target_bootstrap(&next_states, ...).
Verification:
SQLX_OFFLINE=true CUDA_COMPUTE_CAP=86 cargo check --workspace → clean
SQLX_OFFLINE=true CUDA_COMPUTE_CAP=86 \
cargo test -p ml --test sp18_td_lambda_q_next_oracle_tests
→ 3/3 pass
bash scripts/audit_sp18_consumers.sh --check → exit 0
Files:

feat(sp18 v2 P3.T1-T5): adaptive HOLD_REWARD_POS/NEG_CAP producer kernel
Lifts the Phase 2 caps from sentinel-driven cold-start (5.0/-10.0
fixed) to p99(|step_ret|) over Long/Short trade closes × 1.5 safety
factor with Wiener-optimal alpha blend. The Phase 2 consumer
(compute_sp18_hold_opportunity_cost) sees producer-driven slots
[483]/[484] from epoch 1 onward; sentinel branch in the consumer
remains as the cold-start fallback path (zero-trade-close epoch ⇒
producer early-returns ⇒ slots stay at sentinel ⇒ consumer falls
through to the +5/-10 macro defaults — bit-identical to pre-Phase-3).
Mirrors SP14 P0-A reward_cap_update_kernel structural template with
three differences: (1) filter (is_close && step_ret != 0) — both
winners AND losers (the consumer needs the magnitude scale of *all*
Long/Short closes); (2) Welford-derived Wiener-α (slots [487..493))
replaces fixed α=0.01, with floor at WELFORD_ALPHA_MIN=0.4 per
pearl_wiener_alpha_floor_for_nonstationary (the policy-realised
distribution is intrinsically non-stationary as the policy adapts);
(3) bounds [0.5, 50.0] (vs. position-side [1.0, 50.0]).
Atomic single-commit per feedback_no_partial_refactor:
- crates/ml/src/cuda_pipeline/hold_reward_cap_update_kernel.cu (NEW)
- crates/ml/build.rs cubin manifest entry
- HoldRewardCapUpdateOps in gpu_aux_trunk.rs (new struct + impl)
- HOLD_REWARD_CAP_UPDATE_CUBIN static + struct field +
launch_hold_reward_cap_update method + constructor instantiation +
field-init in gpu_dqn_trainer.rs (5 sites)
- Per-epoch boundary launch in training_loop.rs right AFTER
launch_reward_cap_update (shared step_ret/trade_close source buffers,
independent ISV slot pairs)
- HEALTH_DIAG[N]: hold_reward_cap [pos={:.4} neg={:.4} fire_rate={:.4}]
- 3 GPU oracle tests (T5 producer-drives-slots, Pearl-A REPLACE,
no-closes preserves-isv) — all pass on local RTX 3050 Ti
- Phase 3 close-out sections in docs/sp18-wireup-audit.md and
docs/dqn-wire-up-audit.md
Pearls applied: feedback_no_atomicadd, pearl_first_observation_bootstrap,
pearl_wiener_optimal_adaptive_alpha, pearl_wiener_alpha_floor_for_nonstationary,
pearl_no_host_branches_in_captured_graph, pearl_symmetric_clamp_audit,
pearl_audit_unboundedness_for_implicit_asymmetry (NEG = -2 × POS at
producer time, single source of truth), feedback_isv_for_adaptive_bounds,
pearl_fused_per_group_statistics_oracle.
Validation: cargo check --workspace clean; 3 GPU oracle tests pass on
local RTX 3050 Ti; scripts/audit_sp18_consumers.sh --check exits 0
(no fingerprint drift in tracked sections).
Plan: docs/superpowers/plans/2026-05-08-sp18-reward-shape-hold-attractor.md
Phase 4-5 (B-leg target-net forward + q_next replacement) follows.

chore(sp18): refresh audit fingerprint for archaeology cleanup self-references
The cleanup commit's own additions to docs/dqn-wire-up-audit.md (the 2026-05-09 archaeology-cleanup-pass entry) cite HOLD_COST_SCALE_INDEX, hold_cost_scale_update_kernel, and HOLD_COST_INDEX by name in the prose describing what was stripped. The audit script's per-section grep counts those legitimately, producing a +1/+1/+4 hit-count drift on docs/dqn-wire-up-audit.md across the slot 380, slot 461, and hold_cost_scale_update_kernel sections respectively. Regenerate the fingerprint snapshot in docs/sp18-wireup-audit.md so `scripts/audit_sp18_consumers.sh --check` passes against the new post-cleanup baseline.

feat(sp18 v2 P1.T3-T6): atomic delete SP13/SP16 hold_cost_scale chain
Deletes the entire reactive Hold-cost controller chain from SP13 P0a / SP16
P2 / SP16 T3 atomically — replaced by the SP18 D-leg structural opportunity-
cost reward landing in Phase 2.
Per DD7(c): observation chain preserved (slots 380, 382). Slot 380 becomes
constructor-init-only diagnostic at HOLD_COST_BASE=0.005, never updated.
18 consumer sites deleted (8 from plan checklist + 10 from A1-A10 audit
expansion):
Production code:
- 3 reward subtraction sites (replaced with Phase 2 placeholder comments)
- hold_cost_scale_update_kernel.cu (file deleted)
- HoldCostScaleUpdateOps struct in gpu_aux_trunk.rs (~120 lines)
- launch_hold_cost_scale_update in gpu_dqn_trainer.rs (forwarder)
- Host controller block in training_loop.rs (~60 lines)
- Slot constants [461..468) in sp14_isv_slots.rs
- HOLD_COST_CONTROLLER_GAIN/FLOOR/CEIL constants in sp13_isv_slots.rs
- state_layout.cuh mirror constants for [461..468)
- build.rs cubin manifest entry
- 7 fold-reset registry entries + 7 dispatch arms
Tests:
- sp14_oracle_tests.rs lines 2173-2926 (11 tests + helpers, ~750 lines)
— these include_bytes! the deleted cubin and cannot survive
- lock_sp18_v2_pp4_retired_chain test (deleted, no inverse-contract
replacement — locking a deletion is pointless ceremony per user call)
Layout fingerprint: range [461..468) is RESERVED gap (SP14-C.1 pattern;
ISV_TOTAL_DIM stays at 507 for checkpoint compatibility). Layout fingerprint
seed updated atomically: HOLD_COST_SCALE + HCS_* slots replaced with
RESERVED_GAP_461_TO_468=SP18_P1_RETIRED marker.
INTERIM STATE: 3 reward sites are now missing the per-bar Hold cost. This
is forbidden to L40S-dispatch until Phase 2 lands the
compute_sp18_hold_opportunity_cost device fn that replaces the deleted
subtraction. The audit doc records this hold.
Validation: cargo check --workspace clean; cargo test -p ml --lib passes
(state_reset_registry::every_fold_and_soft_reset_entry_has_dispatch_arm,
sp16_t3_wiener_welford_slot_layout_locked, sp18_combined_slot_layout_locked,
sp18_shrink_perturb_slot_layout_locked, sp18_fold_reset_entries_present —
all OK). Audit fingerprint: per-bar Hold-cost subtraction sites count
13 → 0 (smoking gun for complete deletion).

feat(sp18 v2 P1.T1+T2): pre-dispatch consumer-audit script + pre-commit hook
Phase 1 Tasks 1.1 + 1.2 of docs/superpowers/plans/2026-05-08-sp18-reward-shape-hold-attractor.md.
Per the plan's audit-first design: surface every live reference to the
SP13/SP16 Hold-cost-scale chain (D-leg) and the TD(λ) `q_next = rewards`
self-bootstrap (B-leg) BEFORE atomic deletion. This catches the SP17-style
"missed quantile_q_select consumer" failure mode where a sweeping refactor
left a dangling reference that compiled but broke at runtime.
What lands
- `scripts/audit_sp18_consumers.sh` — 17-section grep that walks every
consumer pattern from the plan's locked checklist (D-leg slot 380,
461, [462..468) HCS_*, hold_cost_scale_update kernel, hold_rate_observer
kernel retained chain, build.rs cubin manifest, state_layout.cuh
mirror constants, state_reset_registry entries, plus B-leg
td_lambda_kernel launch sites, q_next origin, rewards_out consumers,
PER priority sites, replay buffer schema, c51_loss target-Q origin,
target_params_buf consumers, PopArt slot 63 references). Three modes:
default (full grep output), `--fingerprint` (per-section per-file hit
count for diff-able snapshots), `--check` (diff fingerprint vs locked
snapshot in docs/sp18-wireup-audit.md, exit 1 on drift).
- `docs/sp18-wireup-audit.md` — Phase 1 Task 1.1 outcome with two
sections of import:
1. The plan's locked checklist (8 entries the plan author explicitly
identified as deletion targets).
2. The 10 ADDITIONAL CONSUMERS surfaced by the audit (A1-A10) that
the plan-author missed. Per the task input's halt-on-drift
directive, Phase 1 Tasks 1.3-1.5 (atomic deletion) are HALTED
pending human review of the expanded scope. The audit doc is the
spec-amendment record.
3. A locked fingerprint snapshot the pre-commit hook uses for drift
detection on subsequent commits.
B-leg verification confirms B-DD4 (no PER migration) + B-DD1 (target_
params_buf reusable) + the single q_next bootstrap site at
gpu_experience_collector.rs:4143.
- `scripts/pre-commit-hook.sh` — Invariant 7 list extended with the new
audit doc; new `check_sp18_consumer_audit` step runs the audit script
in `--check` mode whenever a commit touches the chain files
(experience_kernels.cu, hold_*_kernel.cu, state_layout.cuh, sp1[3-8]_
isv_slots.rs, gpu_dqn_trainer.rs, gpu_aux_trunk.rs, gpu_experience_
collector.rs, state_reset_registry.rs, training_loop.rs, build.rs,
sp1[3-8]_oracle_tests.rs). Drift triggers a hook failure with a
pointer to the regeneration command. This is a generalisation of
Invariant 7 and addresses Open Q-B from the spec (audit-as-pre-commit
hook for SP-chain consumer drift).
Findings (HALT trigger)
The audit found 10 consumers NOT in the plan's locked 8-site checklist:
A1 — gpu_aux_trunk.rs:1240-1323 HoldCostScaleUpdateOps struct + impl
(84 lines; the plan said launcher was in gpu_dqn_trainer but the
real struct/impl lives in gpu_aux_trunk; trainer just has a thin
forwarding method)
A2 — sp14_oracle_tests.rs:2174-2920 11 GPU oracle tests (~750 lines)
directly exercising the deleted kernel via include_bytes!
(sp16_phase2_hold_cost_scale_climbs_with_overrun + 10 others)
A3 — training_loop.rs:8971-9043 7 dispatch arms in reset_named_state
(slot 461 + HCS_* slots 462-467); contract test
every_fold_and_soft_reset_entry_has_dispatch_arm requires
atomic deletion alongside registry entries
A4 — gpu_dqn_trainer.rs:23200-23216 constructor block writing
HOLD_COST_BASE to slot 380 (RETAINED per DD7c, comment requires
update)
A5 — gpu_dqn_trainer.rs:617, 2245-2256 doc-block prose
A6 — sp13_isv_slots.rs:75-77 HOLD_COST_CONTROLLER_GAIN/FLOOR/CEIL
constants (HOLD_COST_BASE retained for A4)
A7 — gpu_experience_collector.rs:5579-5585 stale comment doc-ref
A8 — sp5_isv_slots.rs:325-327 comment doc-ref
A9 — state_reset_registry.rs:1138-1271 7 already-RETIRED entries
promote to FULL DELETION
A10 — state_reset_registry.rs:2256-2308 lock_sp18_v2_pp4_retired_chain
contract test asserts retired entries STILL EXIST; must be
deleted/rewritten when entries are removed
None of these are architectural surprises — they're straight extensions
of the atomic-deletion scope. But per the task input's halt-on-drift
directive ("If your audit surfaces ANY additional consumer, halt and
report — do NOT proceed with deletion ad-hoc"), Phase 1 Tasks 1.3-1.5
HALT pending human sign-off on the expanded scope.
Path forward (next phase)
Either expand the atomic-deletion commit scope to cover all 18 sites
(8 plan + 10 audit-surfaced) — recommended per `feedback_no_partial_
refactor`; the audit doc serves as the spec-amendment record — or
human-review the audit doc and explicitly approve/reject each A* entry.
The audit doc + script + hook are the pre-condition for either path
and ship together as Tasks 1.1 + 1.2 of Phase 1. Tasks 1.3-1.6 await
human go-ahead.
Branch is at INTERIM STATE: NOT runnable for L40S smoke between this
commit and the post-Phase-1.6 close-out. The interim is purely-additive
(audit script + hook + doc); the actual deletion that creates the
"3 reward sites missing Hold cost" interim from the plan's Task 1.5
has NOT yet been performed.
