GIE-Soliton: Numerical Survival - Atomic Integrity Addendum & Microarchitecture-Grade Numerical Robustness

The GIE-Soliton Numerical Survival architecture upgrades its pressure estimation and manifoldtrigger logic by introducing an Atomic Integrity filter that measures transactional density behindprice displacement. The primary objective is to suppress non-physical gradient spikes induced byhigh-frequency microstructure effects while preserving responsiveness to volume-supported breakregimes.The implementation pairs integrity gating with a “Numerical Survival” kernel designed for predictable low-latency execution on commodity x86-64 CPUs. A 2-way unrolled AVX2/FMA projection core balances throughput with register safety, strict alignment contracts eliminate undefinedbehavior, and a fail-fast poison detector rejects NaN/Inf samples. Inter-thread state exchange isimplemented via a double-buffered manifold matrix channel and a minimal SeqLock for compactscalars, both tuned for low contention. Numerical robustness is enforced with a trust-region gateusing higher-precision accumulation by default, with an optional compensated summation modefor boundary-sensitive deployments.Empirically, the August 5 extreme-market trace exhibits a clean separation: rapid breakpointsmaintain integrity above threshold and are admitted to Physical Lock, whereas bottom-churnphases display deceptive gradient volatility but integrity collapses toward zero, causing the systemto remain in Phoenix Standby and reduce state thrash.
