reward_subsystem_controller_kernel: 5 canaries → 10 outputs, true Z-score
(delta_ema/sqrt(var_ema)), sigmoid blending, weight renormalization to Σ=1,
saboteur post-clamp, curiosity permanent floor (0.2 × bound). Pearls A+D
chained on outputs per spec §3.4.1.
novelty_simhash_kernel: 42×16 random projection → 16-bit SimHash code,
1M-slot bucket count table for novelty signal `1/sqrt(1+count)`. Race-
tolerated update per feedback_no_atomicadd (under-counts bias novelty
UPWARD — safe direction).
novelty_simhash_proj_init_kernel: Philox-seeded GPU init for the
projection matrix (CPU is read-only per feedback_no_cpu_forwards).
HEALTH_DIAG `sp11_reward` line emits 10 outputs + improvement_z each
epoch. Reset registry: novelty hash table reset arm wired (closes the
A0 deferral); projection matrix is frozen at trainer init for run
lifetime, not reset.
All 20 SP11 slots populate every step. No consumer reads them yet —
training behavior unchanged from A1. 3 new GPU oracle tests pass on
RTX 3050 Ti (controller midpoint, weight renorm, saboteur clamp).
