What the model reads

No new sampling systems: we use what production already measures. If signals are missing — minimal sensor upgrades.

Technology and security

Physicochemical core + industrial AI

The material balance closes the flows of feedstock, fuel and products; the heat balance closes the process energy. The Gibbs reactor computes the equilibrium gas-phase composition via Gibbs energy minimization; thermohydraulics describes the path from unit to stack.

On top of the physics, correcting blocks of industrial AI are trained on mode archives and instrumental measurements. This is not an LLM: the model does not learn in production; retraining follows a protocol with subsequent validation by the mobile complex.

This architecture yields explainable results: every computed value decomposes into contributions of physical blocks and corrections.

Isolated runtime

The computing core runs in an isolated environment: model and input-data checksums are verified before every calculation cycle, self-tests confirm integrity, and any interference is logged.

Data that fails checks is flagged as unreliable — the system fundamentally does not fabricate values. This is a key requirement for using results in supervision.

The platform is the Russian Astra Linux OS; the software is in the register of domestic software and suits critical infrastructure.
