Static-analysis diagnostic catalog

Generated from the canonical rule registry at internal/staticanalysis/rules/registry.json. Run pnpm docs:generate-reference after changing rule metadata. Do not edit this page by hand.

Use xlflow rules to inspect the same metadata from an installed xlflow binary. VBA000 is a synthetic analysis-failure diagnostic and is intentionally outside the registry; UserForm FRM... and UFY... diagnostics are outside this catalog.

Blocks source preflight describes the registry default. A project may list a blocking diagnostic in [preflight].allowed_diagnostics to let workbook automation proceed without disabling the diagnostic or changing its severity; applied waivers are reported as command warnings.
