[{"type":"thinking","thinking":"The Edit tool STILL refuses despite the fresh read. This is bizarre — the text is literally there. The issue might be the tool's read-tracking requires the FULL file to have been read (it says \"File was only partially read\"). Earlier in the session the Edit tool worked with offset reads... — maybe there's a size limit where partial reads stop counting, and the file grew past it (~1400 lines?). The reliable path: use a small python script FILE (not heredoc, which mangled the unicode) to do the replacement. Let me write a python file with the Write tool (which handles unicode fine) and run it.","signature":""},{"type":"text","text":"The Edit tool refuses on the large file's partial reads.
