No existing value changed meaning; code branching on \"avoid\" is unaffected, and code branching on \"clear\" now gets strictly fewer, better-founded clears. 2026-09-21 (P96): a clear verdict now also requires the MEASURED sale of your position to return at least 90% of the size you asked about. Below that the answer is \"unknown\" with the reason exit-below-90pct — no trap was proven, but the exit we measured is not there at this size. Again strictly fewer clears; avoid is untouched.",
