Writing Rules

Add a rule module, register it in src/rules/_index.ts, add unit coverage, add docs, and ensure the rule emits normalized findings.

Variant-Aware Rules

KiCad 10 variants are available through project files and projects[].variants configuration. Use parseVariants from src/kicad/variants.ts when a rule must compare variant DNP overrides with BOM or schematic state.

CLI and Action callers can select an active KiCad variant with --variant or the variant action input. BoardReadyOps uses that value for variant-aware rules. KiCad DRC and ERC do not expose a --variant option in kicad-cli, so the KiCad report adapter passes the value as --define-var BOARDREADYOPS_VARIANT=<name> instead of using an unsupported flag.

Jobset-Aware Rules

Use parseJobset from src/kicad/jobset.ts to read .kicad_jobset files. A jobset-aware manufacturing rule should skip cleanly when no jobset file is present and report missing enabled outputs with resource.kind = "manifest".
