  "report": "TIE, FUNCTIONALLY EQUIVALENT.\n\nBoth readers would keep Stonebriar performing, timely answer the cure notice, perfect the rock/tank and payment claims, demand proof concerning owner nonpayment, and record a conservatively calculated lien well before Day 19. Answer A’s unsupported expansions would be rejected through ordinary verification against the supplied lien rule and record, leaving the same materially safe course prescribed by Answer B.\n\n[A] rejected: inclusion of unapproved measured rock-removal costs in the lien — cited governing rule limits liens to unpaid contract balances and approved changes.\n[A] rejected: owner statement establishes estoppel on prime-contract notice and requires a liquidating agreement — record lacks the prime contract, agency facts, and applicable pass-through rules.\n[A] rejected: withholding and default notice presently establish active interference or bad faith — record lacks facts establishing wrongful withholding, deliberate obstruction, or denial of a time extension.\n[A] rejected: lien filing may itself be a subcontract default — record lacks such a subcontract provision.\n[B] rejected: owner direction may bind Corestone through agency or ratification — record lacks agency or ratification facts.\n\nFailed candidates. Lien amount: no-safe-neutralization element failed because ordinary comparison with the supplied lien rule removes Answer A’s unapproved rock amount before filing.\nFailed candidates. Active-interference treatment: likelihood failed because both readers must investigate before asserting the exception, and no different present conduct or recovery is established.\nFailed candidates. Owner-statement/pass-through treatment: record support failed because the necessary prime-contract and agency terms were not supplied.\nFailed candidates. Cure-response timing: concrete consequence failed because both schedules deliver a substantive response within the seven-day period while performance continues.\nFailed candidates. Lien-recording timing: concrete consequence failed because both schedules record with meaningful time before the jurisdictional deadline.\nFailed candidates. Additional payment-bond, waiver, and procedural checks: different conduct failed because these are verification steps rather than demonstrated changes to the client’s position.\n\nHard stop. The sentence cannot be completed with a concrete, record-supported consequence because both answers place Stonebriar on the same materially correct and safe path.",
