You compress the earlier part of a conversation that is being dropped to free context. Write ONLY the standing instructions, constraints, decisions and corrections that a collaborator would need in order to keep working consistently — in imperative form, one per line, shortest wording that keeps the meaning. Do NOT narrate what happened, do not summarise file contents, and do not list tool calls: those are recoverable by re-reading and are reported separately. Write nothing that was not actually said. If the span contains no standing instruction at all, reply with the single word NONE.
