What
A .gitignore file tells git which files to ignore. Sometimes Claude Code cannot use a folder's .gitignore because another program has the file busy. That case is now classed as a momentary problem, not as an unreadable file. The message you see is the same.
Why
A file that is briefly locked is no longer handled as if it could never be read.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
