Request the capability.
Define the physical state, decision and evidence that would make the answer useful.
Engine · Evidence-controlled architecture
The LINUR Engine connects geometry, fields, phase, propagation and energy flow to a decision. Each application keeps the physical operators and evidence boundary its domain requires.

Map the admitted system and preserve the frozen conditions.
Expose which assumptions, constraints and dependencies govern the result.
Act only where the evidence and validation stage permit it.
Selective depth
A request does not load one enormous model. The Engine descends through a governed capability pyramid until it reaches the individual physical state required for the decision.
Conservation, geometry, coupled fields and the certified numerical core.
Matter, energy, devices or cosmic systems select the relevant physical branch.
The branch narrows to an atom, molecule, material, field system or device family.
Prediction, reconstruction, optimization or control defines the required capability.
Only the admitted state, conditions and uncertainty needed for the decision are loaded.
How LINUR learns from reality
The Engine identifies the most informative next experiment. Laboratories provide physical evidence. Every result first enters an immutable evidence registry; some measurements are declared calibration data, while others remain unopened held-out tests.
Connected, not interchangeable
The layers may couple, but one cannot silently stand in for another. Every connection carries units, uncertainty, provenance, authority and the exact operator version that produced it.
Isotope composition, nuclear energy levels, admitted decay channels and intrinsic transition operators.
Electronic configuration, charge state and polarization.
Chemical identity, connectivity, orientation, equilibrium scale and local stability.
Connected geometry, energy, conformational branches and environmental response.
Crystal organization, defects, collective geometry and phase.
Transport, thermal and electromagnetic response assembled from admitted lower layers.
Boundaries, loads, operating conditions and the physical decision being tested.
Immutable measurements, uncertainty and provenance used for calibration or held-out comparison.
How a capability request moves
Define the physical state, decision and evidence that would make the answer useful.
Reuse every certified layer that already applies and identify the exact missing interface.
Build the missing operator against independent controls before the held-out answer is opened.
Seal the new layer additively, preserve its limits and return it to the requesting application.
The pyramid routes each request through versioned capabilities while the underlying implementation remains confidential.
If a required layer is absent, the Engine returns a precise gap or next experiment instead of fabricating an answer.
