/**
 * Regression coverage for GitHub issue #19192, part 1 of 4.
 *
 * Exercises the fmcs_company validator in isolation across the settings
 * and actor context matrix. Per Snipe's FMCS adversarial-tests memory,
 * cover strict and floater and non-FMCS with superuser and non-superuser
 * actors, plus the CLI (no-auth) posture and the pseudo-company carve-out
 * for uncompanied actors in strict mode.
 *
 * The rule is exercised on its own (not against each model's full $rules)
 * so unrelated pseudo-rules like License::limit_change don't crash the
 * runner. A companion sanity file, FmcsCompanyRuleWiringTest, asserts
 * every affected model's $rules array carries the rule.
