The eleven artifacts

Artifact What it answers Licence
physics-lint One command for all the checkers. SARIF for CI. Apache-2.0
sparam-lint Is an S-parameter model physically possible? Five laws + a negative control. Apache-2.0
maxwell-lint Does a coupling extractor predict impossible physics? Screening ceiling k ≤ 1. Apache-2.0
abstain-bench Does a model know when to shut up? Abstention recall, never pooled with accuracy. Apache-2.0
touchstone-tools Read, write and convert N-port files. Refuses to emit what it would not read. Apache-2.0
interval-core Validated interval arithmetic. Ships the enclosure self-check. Apache-2.0
physics-lint-action The same checks, in your CI. Apache-2.0
physics-lint-mcp A physics oracle an AI agent can call. Apache-2.0
sparam-conformance 11 labelled networks with verified ground truth. Grades the graders. CC-BY-4.0
screening-ceiling A certified impossibility result + 27 counterexamples. Zero-dependency verifier. CC-BY-4.0
physics-lint (Space) Try three of the checks in a browser, no install. Apache-2.0

Each repository carries its own CLI reference, API table, troubleshooting section and worked example. This site covers what is true across them.

Contributing

Every repository has a CONTRIBUTING.md stating one non-negotiable rule, and they differ by design:

  • sparam-lint — every new law needs a violator that the law must reject.
  • touchstone-tools — the writer may never emit what the reader would refuse, and a singular answer is refused rather than regularized.
  • interval-core — an enclosure may widen, never narrow.
  • sparam-conformance — new cases need construction-derived labels, not another tool's opinion.

The most useful contribution to the portfolio is a new pathological case for the corpus: a network that breaks a checker in a way the corpus does not yet cover.
