  "purpose": "Compute the ACA employer-mandate affordability percentage under each of the three IRC 4980H(a)(1)(B) safe harbors (W-2 wages, rate-of-pay, federal poverty line) against a supplied lowest-cost self-only monthly premium, using the version-pinned 2026 affordability threshold (9.96%, IRS Rev. Proc. 2025-25). Returns per-harbor affordability verdicts and which harbor(s) the offer satisfies. Root node of the aca-226j-response-composer chain. Not tax or legal advice -- calculation evidence only. Zero network, zero PII.",
