refactor(sp14-c): atomic α machinery deletion + aux trunk ISV slot allocation
Phase C.1 of SP14 Layer C separate-aux-trunk refactor. Single atomic
commit per feedback_no_partial_refactor and feedback_no_legacy_aliases —
no DEPRECATED stage.
Deleted (per C.0 audit a7a162d1f):
- alpha_grad_compute_kernel.cu
- sp14_scale_wire_col_kernel.cu
- gradient_hack_detect_kernel.cu (EGF circuit breaker — α-coupled)
- 10 ISV slot constants (K_AUX_ADAPTIVE, K_Q_ADAPTIVE,
BETA_RATE_LIMITER_ADAPTIVE, AUX_DIR_ACC_VARIANCE_EMA,
ALPHA_GRAD_RAW_VARIANCE_EMA, GATE1_OPEN_STATE, ALPHA_GRAD_RAW,
ALPHA_GRAD_SMOOTHED, AUX_DIR_ACC_POST_OPEN_MIN,
GRADIENT_HACK_LOCKOUT_REMAINING) plus 16 supporting sentinels and
structural-anchor constants
- 31 reference sites across 7 files (collector, trainer, training_loop,
fused_training, batched_backward, build.rs cubin manifest,
state_reset_registry)
- 3 oracle tests (alpha_grad_adaptive_beta, alpha_grad_schmitt_hysteresis,
gradient_hack_circuit_breaker_fires)
Added:
- 6 aux trunk control plane ISV slots [444..450):
AUX_TRUNK_LR (444), AUX_TRUNK_BETA1 (445), AUX_TRUNK_BETA2 (446),
AUX_TRUNK_EPS (447), AUX_TRUNK_GRAD_CLIP (448), H_S2_AUX_RMS_EMA (449)
- 6 reset registry entries (5 Invariant-1 anchors + Pearl-A first-
observation EMA)
- 6 reset_named_state dispatch arms (mirrors SP5 Layer A pattern)
- ISV_TOTAL_DIM bumped 444 → 450
Preserved:
- dir_concat_qaux_kernel.cu (Coupling A: forward feature wire)
- q_disagreement_update_kernel.cu (diagnostic-only)
- q_disagreement_* ISV slots (383, 384, 389) — HEALTH_DIAG consumer
Build clean (cargo check -p ml --tests --all-targets, RTX 3050 Ti);
4 surviving oracle tests pass (dir_concat_qaux_correct + 3 q_disagreement_*).
ISV layout: deleted α slots left as RESERVED gap (NOT compacted) for
checkpoint fingerprint compatibility.
