After any subagent or opencode run that edits files, read_file or grep each edit back before proceeding. The 15-second verification saves the 30-minute re-do. For multi-edit batches, grep for each edit individually — silent no-ops are invisible to a single spot-check, even when the subagent reports all edits landed.
