226J Response Evidence Pack Builder

Assembles a replayable evidence pack responding to an IRS Letter 226J proposed Employer Shared Responsibility Payment assessment: recomputes the exposure position against the IRS-asserted figure, computes the response-window deadline from the supplied letter date (DRAFT-PINNED at 30 days pending a confirmed citation), and records a named-HR/benefits-officer attestation closure. Recompute and respond before the window closes: not a guarantee of abatement.

Scope
Terminal node of the aca-226j-response-composer chain (art-298→299→300). This is the employer's replayable dispute evidence, not a determination of liability or a guarantee of abatement.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `build_226j_response_evidence_pack`. Task: Assemble a replayable evidence pack responding to an IRS Letter 226J proposed ESRP assessment: recomputed exposure vs the IRS-asserted figure, a computed response-window deadline, and a named-human attestation closure.
Call it with arguments: {"policy_parameters":{"letter_date":"2026-08-03","irs_asserted_esrp_annual":567800,"affordability_result":{"tax_year":"2026","satisfies_any_harbor":false,"harbors_satisfied":[]},"esrp_result":{"tax_year":"2026","controlling_penalty":"a","controlling_exposure_annual":567800},"disputed_employee_ids":["EMP-0001","EMP-0002"],"attestation":{"name":"Jordan Rivera","title":"VP, Total Rewards","timestamp":"2026-08-10T15:00:00Z"}}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
