Methodology and sources
Every calculator documents its own methodology, source basis, and assumptions. This page explains the traceability rules that apply platform-wide.
How Xarpis labels every check
- Implemented
- The check computes a result. Its formula is traceable to a verified basis — a named standard clause supplied for validation, or a public-domain mechanics identity — and it is covered by validation cases.
- Awaiting source
- The check is defined but does not compute. Its source basis has not been verified yet, so no result is shown — a labelled placeholder is shown instead of a guess.
- Out of scope
- The check or configuration is deliberately outside the calculator's validated scope. The tool says so explicitly; no result is inferred.
No copyrighted standard text is reproduced on Xarpis. Source registries store metadata only — code, edition, and clause references — and code-specific coefficients are never hardcoded without a verified source.
