…d proofs PR #22263 replaced BB_ASSERT(val.on_curve()) with throw_or_abort in field_conversion.hpp. Unlike BB_ASSERT, throw_or_abort is not gated by BB_DISABLE_ASSERTS(), so corrupted IPA proof data now throws std::runtime_error during deserialization in batch_check(). This crashed ChonkBatchVerifierTests.RandomMixedBatches which relies on graceful failure handling for tampered proofs. Wrap batch_reduce_verify in try-catch so exceptions trigger bisection (isolating the bad proof) instead of crashing.
