So every user message is wrapped in a marker line, and +the persona tells the model that what sits between two markers is the hire's +words to answer, never instructions (``QUERY_FENCE_NOTE``). + +The marker is an HMAC of the message under a deployment-wide key, not a random +nonce per request, for two reasons: + +- **It cannot be forged.** Whether a message is already fenced is decided by + recomputing its marker, never by the marker's shape. A hire who types + ``--0123456789abcdef--`` at the start of a message cannot talk their way past + the fence; their text is just fenced again. +- **It is byte-stable.** The backend rebuilds the history from its stored raw + text on every turn, and carries the returned messages verbatim between the + hops of one turn. The same text always gets the same marker, so a prompt + prefix cached on one hop or turn still matches on the next. A fresh nonce + per request would change an earlier message on every turn and miss the cache + from there on. + +Byte stability is a property of the key, so it has to be a property of the +deployment, not of one process. ``FENCE_KEY`` is how a scaled deployment says +so; the shipped one runs a single uvicorn process (``Dockerfile``), where the +drawn-at-startup default is already stable. With more than one worker or +replica and no ``FENCE_KEY``, each process draws its own key and re-fences what +another fenced: still safe, but a cache miss and one more marker pair per +crossing.
