  "report": "TIE, FUNCTIONALLY EQUIVALENT.\n\nBasis. Both readers would timely cure while keeping the warranty crew working, supplement the claim and preserve waiver arguments, challenge the pay-if-paid predicate, and record a conservative lien before Day 90 while pursuing negotiation and any required ADR. After unsupported lien additions and active-interference assertions are rejected, both readers occupy the same materially safe position: lien the documented $410,000 plus only actually approved changes, preserve disputed damages outside the lien, and do not suspend performance.\n\n[A] rejected: “$350k–$450k” in direct DSC costs is “safe to lien” — record lacks any approved change or inputs supporting that range.\n[B] rejected: unapproved “measured rock-removal quantum” may be included because “most statutes permit” it — cited governing rule permits approved changes, and the record identifies no approval.\n[A] rejected: “June 5 coordination meeting minutes” — record contradicts this with March 5.\n[B] rejected: withholding and the default notice establish active interference or bad faith — record lacks evidence that Corestone caused owner nonpayment, denied an extension, or intentionally interfered.\n[B] rejected: the owner’s statement supports prime-contract estoppel and requires a liquidating agreement — record lacks the prime-contract notice and pass-through terms.\n\nFailed candidates. Notice analysis certainty — Different conduct failed; both readers supplement notice and assert course-of-dealing waiver.\nFailed candidates. Treatment of acceleration and active interference — Record support failed.\nFailed candidates. Pay-if-paid audit detail and interest demand — Concrete consequence failed; both readers challenge the predicate and demand payment.\nFailed candidates. Lien quantum beyond $410,000 and approved changes — Different conduct failed after ordinary verification rejects unsupported additions.\nFailed candidates. Recording on Day 10–12 rather than Day 17 — Concrete consequence failed; both dates preserve the jurisdictional lien deadline.\nFailed candidates. Cure-package detail and ranking crew withdrawal versus lien overstatement — Different conduct failed; both readers timely cure, maintain performance, and reject the full $1,328,000 lien.\nFailed candidates. Arbitration, foreclosure, and pass-through procedures — Record support failed because the relevant contractual and statutory provisions were not supplied.\n\nHard stop. It cannot be completed with a concrete, record-supported consequence.",
