Systems Architecture / State Estimation Engineering

What to call it when talking to engineers: provenance-tracked state estimation, immutable data architecture, formal channel separation.

Real evidence

• ImmutableNCFCATensor with TaintedValue — a genuine, working provenance-tracking write-path, closing a real vulnerability class (value laundering) that was found, diagnosed, and fixed with a full regression suite.
• Deterministic execution kernel — byte-identical output across repeated runs, same seed. A real, checkable reproducibility guarantee.
• 14-class estimator suite (Kalman, particle filter, HMM, ensemble, Bayesian linear, isolation forest, and more) unified under one common interface.

Honest calibration

The architecture and the provenance mechanism are genuinely solid, verified engineering — a real vulnerability was found and closed the way a real security review would, then checked against every other claim in the system, finding one more real instance and confirming three others weren't actually exposed. What's not yet true: the ncfca package's full production form is still missing pieces.
