Scope & limitations

  • Declared ideal or supplied-record model only; no physical inspection, live control, certification or professional approval. Nonzero model inputs have magnitude from 1e-12 through 1e9; zero remains permitted only where the specific semantic model permits it. reportedValue and absoluteTolerance may use smaller finite magnitudes. Explicit matrix pivot/spectral conditioning floor is 1e-12 of the stated scale; symmetric eigensystem stopping is 1e-14 of scale. Matrix and enumeration bounds are input work profiles. Floating arithmetic uses finite double precision and twelve-significant-digit presentation; integral quantities must remain exactly representable. No external device or account is accessed. Aggregate enumeration estimates must not exceed 10000000 elementary work units per request. Use authorized, non-sensitive data.
