This bug will not be reproduced on demand. It will arrive as somebody's report,
hours later, from a browser whose console is long gone — so a `console.warn` is
seen by nobody, and "what did you see?" gets an answer built from memory and a
screenshot.
So the trap now persists. Up to five occurrences in
`localStorage['officer:editor-buffer-trap']`, each carrying the stack at the moment
of the edit, the first 200 characters that arrived, how many, which file, and when.
The question becomes "paste this key", and the answer is complete.
Recording a bug must never become one: private mode, a full quota and a disabled
storage API all throw at that write, and none of them is worth breaking an edit
over. The console line survives either way.
`docs/editor-buffer-corruption.md` is the procedure — what it looks like, the four
candidates already eliminated and why, the one command to ask a reporter for, how
to read each field, what an EMPTY key would mean (either the editor was focused,
making it a paste, or the insertion came in chunks under the threshold), and the
instruction to delete every piece of this once the cause is known. Linked from
TODO.md and from CLAUDE.md's reading list, so somebody handed a report finds it
without grepping for it.
Stated there rather than left implicit: a fix invented without knowing the cause
would hide the symptom on the one screen where it is visible while the mechanism
carried on doing whatever else it does. The corruption is never saved and reopening
the tab clears it, so waiting is cheap and a wrong fix is not.
tsgo clean, frontend builds, 873 pass / 7 fail unchanged.
