Keystone role
Pricing engine only. MGA binds the policy.
Keystone does not bind. This quote is produced by Keystone's Insurance Rail pricing engine from verified per-asset attributes. A licensed MGA partner reviews the quote, applies its underwriting judgment and any additional considerations, and binds the policy on carrier paper. Keystone is the math; the licensed MGA is the counterparty on the policy.

Defensibility appendix

Every bps of discount above traces to a specific verified attribute on a specific asset record. Reinsurance counterparty, state department-of-insurance auditor, or captive-audit reviewer can reproduce the quote from the record. The pricing formula is published; the attribute values are cryptographically signed at ingest and immutable.
