• sharding signals disagree: index file present=True, filename pattern matched=False -- picked whichever signal is available, but this repo's layout is unusual
• found model.safetensors.index.json but shard filenames didn't match the expected NNNNN-of-NNNNN pattern -- fell back to sorting all .safetensors files, verify manually
