Windows + OneDrive: .claude.json corruption cascade from concurrent writes
증상
On Windows 11 with the home directory on OneDrive, ~/.claude.json experienced a cascading corruption event that resulted in complete config loss and a login loop.
원인
Environment variable, configuration file, or initialization parameter missing, malformed, or incorrectly scoped.
해결법
Manual recovery by finding the largest valid .corrupted file in ~/.claude/backups/ and copying it back as ~/.claude.json. The backup files are valid JSON despite the .corrupted naming — Claude Code was correctly saving snapshots before each recovery attempt, it just couldn’t stop the cascade.
