Summary

On native Windows, agent file tools cannot read existing files when a Git Bash, Cygwin, or WSL-style drive path is supplied because the shared path resolver maps the path under the current drive root instead of the requested drive.

Steps to reproduce

1. Run OpenClaw from source on native Windows.
2. Choose an existing file, for example F:\repo\package.json.
3. Call the agent read tool with /f/repo/package.json, /cygdrive/f/repo/package.json, or /mnt/f/repo/package.json.
4. Observe that each call fails before reading the existing file.

Expected behavior

Each supported POSIX drive spelling resolves to F:\repo\package.json and the read tool returns the file contents.

Actual behavior

The resolver treats each input as a current-drive-root path. The three examples attempt F:\f\repo\package.json, F:\cygdrive\f\repo\package.json, and F:\mnt\f\repo\package.json, then fail with ENOENT.

Logs

{"input":"/f/repo/package.json","ok":false,"error":"ENOENT ... access 'F:\\f\\repo\\package.json'"}
{"input":"/cygdrive/f/repo/package.json","ok":false,"error":"ENOENT ... access 'F:\\cygdrive\\f\\repo\\package.json'"}

Screenshots, recordings, and evidence

A deterministic source-level reproduction through createReadToolDefinition fails for all three inputs on the unmodified checkout. The same command succeeds for all three after normalizing recognized POSIX drive forms at the shared file-tool path boundary.

Impact and severity

Affected: native Windows users whose agent receives a path copied or emitted from Git Bash, Cygwin, or WSL.
Severity: blocks read/edit/write workflows for the affected path.
Frequency: 3/3 supported path forms reproduced consistently.
Consequence: the agent reports that an existing file does not exist and cannot continue file work until the user rewrites the path manually.

Additional information

UNC paths and ordinary POSIX paths such as //server/share, /home/..., and /tmp/... are not part of this bug and should remain unchanged.
