Summary

The edit tool occasionally reports "edit failed" in the tool result output, but the file changes are actually persisted successfully to disk. This causes confusion when verifying whether memory updates were saved.

Steps to Reproduce

1. In a regular agent session (not isolated/cron), use the edit tool to modify a file
2. Example: Edit MEMORY.md to update a section
3. Observe: Tool output shows error: "Edit: ... failed"
4. Verify: Read the file or grep — changes are actually present

Expected Behavior

If edit succeeds, tool should report success. If tool reports failure, changes should not persist.

Actual Behavior

Tool reports failure but changes persist correctly.

Example

Edit to ~/.openclaw/workspace/MEMORY.md (94 chars) failed

But checking the file:

grep "Blog Writing" ~/.openclaw/workspace/MEMORY.md
# Shows the edit was successfully applied

Environment

• OpenClaw: 2026.3.1
• OS: Linux 6.12.73+deb13-amd64 (x64)
• Install: npm global
• Node: v25.6.1

Related Issues

• [Bug]: Write tool reports error in isolated cron agentTurn jobs despite file being successfully created #30773 — Write tool reports error in isolated cron jobs despite file being successfully created (same symptom, different tool/context)
• Edit tool does not expand ~ (tilde) in file paths #30669 — Edit tool does not expand ~ (tilde) in file paths (potential related path resolution issue)

Additional Notes

This appears to be a false error in the tool result reporting — the actual file operation succeeds, but something in the verification/result path reports failure incorrectly. Given #30773 shows the same pattern for write, there may be a common issue in how tool results are validated/reported.
