Scope study of a third-order event predictor for loss of ignition at strong coupling: protocol, pilot data and audit trail

Protocol, pilot addendum, code, pilot and confirmatory results, and audit trail for a scope study of the third-order event approximation for the upper ignition boundary in bistable networks. The protocol and pilot addendum were deposited publicly (version 1.0) before the confirmatory run (seed 2026110220, 3 replicates, 480 cases); the pilot used seed 2026110210 (160 cases). Version 1.1 adds the confirmatory results, their audit, the analysis, independent-integrator checks and notes. Frozen-file hashes are in MANIFEST_frozen.sha256 and all file hashes in PACKAGE_MANIFEST.sha256. verify_deposit.py checks the record and reproduces the reported numbers.
