+- **Handoff:** a read by OpenCode's `read` or Claude Code's `NotebookRead`
+  is named by its file, not by its input as JSON. So is a failed OpenCode
+  `edit` or `write`, or Claude Code's `NotebookEdit`, under "What failed",
+  and it no longer shows there once a later one of the same file passed,
+  as a failed Claude Code `Edit` already didn't.
