The latest editor changes for ${type} "${path}" could not be

Error message

The latest editor changes for ${type} "${path}" could not be saved and are not readable; retry once the editor saves.

What it means

Thrown while building the diff_workspace_item output when the editor's unsaved changes for the item cannot be flushed to the draft store and are therefore not readable. The 'draft' side of the diff would silently be stale, so the tool fails loudly instead of showing the model a diff against outdated code.

Solutions

  1. Wait for the editor's save to complete, then re-run the diff tool
  2. Check for draft-store or network errors that blocked the flush
  3. Fall back to the saved draft only after confirming the editor has nothing unsaved
Defensive patterns

Strategy: retry
