Code and derived data for: A steadily flowing glacier and no detectable precursor before the 11 October 2026 Budhi Gandaki rock–ice avalanche and flood, Nepal

Analysis code, figure scripts and derived data for an EarthArXiv preprint on the 11 October 2026 Ungilung / Budhi Gandaki rock–ice avalanche and flood (Gorkha, Nepal). Includes verify_paper5.py, which recomputes the key reported values (Landsat 9 grid test, ITS_LIVE glacier speeds, ERA5 weather, NISAR L-band phase on the source). Code written with AI assistance (Claude, Anthropic), as declared in the preprint. Version 1.1.0 (30 October 2026) adds the scripts, derived data and checks for preprint version 2 (Sects. 3.8 and 3.9: the first clear Sentinel-2 images after the event, a 2025 same-season control, and NISAR coherence across the event; ERA5 for 10–12 October).
