A0 follow-up (1e5a65912) fixed two stale refs from code-quality review.
Implementer surfaced 3 more accumulated across SP4/SP5/Layer-D:
- :537 sp4_wiener_state — claimed 543 floats with growth chain 141→207→213→543
- :974 sp5_pnl_aggregation — claimed SP5_WIENER_TOTAL_FLOATS=573 (post-D2 stale)
- :989 sp5_health_composition — same =573 stale
- :1009 sp5_training_metrics_ema — claimed =582 (post-D3 stale)
All four converted to formula form (71 + SP5_PRODUCER_COUNT) × 3 matching
A0 fix-up pattern. Drops brittle growth chains in favor of a derivable
formula. Audit doc entry added per Invariant 7. cargo check + state_reset
_registry tests 4/4 pass.
