Move volatile current time and middle-pane data out of the system prompt and into a hidden userMessageContext stored on each user message. Reconstruct the LLM-facing message from this persisted context so older conversation turns remain stable across later requests while UI-facing content stays unchanged. Keep finite branch instructions such as voice, search, code mode, agent notes, and workdir behavior in the system prompt so each conversation can still benefit from reusable prompt-cache prefixes.
