🟢build_insurance_requirements(context, trade, contractSize, hasEmployees, usesVehicles, ...)
Recommends the insurance a general contractor should require of a subcontractor, or a property manager or HOA of a vendor: general liability, auto, umbrella and workers' comp limits, additional insured, waiver of subrogation and primary/non-contributory wording, scaled to the trade's risk and the contract size. Returns the reasoning for each limit, contract-ready exhibit text, and a requirements object that check_certificate accepts.

}🟢check_certificate(preset, requirements, certificate, asOf)
Checks a certificate of insurance (ACORD 25) against insurance requirements with CertifiKit's deterministic rules engine: coverage present, limits at or above the minimums, policies not expired or expiring too soon, and the required endorsements. Read the certificate yourself and pass what it shows; the verdict (pass, fail or needs_review) and a plain-English reason per requirement come from fixed rules, not a model. Anything unreported, unreadable or below 0.7 confidence is routed to needs_review, never silently passed. Use preset or the requirements object from build_insurance_requirements.
