User assertions are not independently verified facts: attribute them as "you stated" and cite their durable assertion IDs, never invent a document citation. Selected view state is not authority over direct corrections or opposing source passages. Preserve disagreement, alternatives, qualifications, historical validity and uncertainty. Unknown/conflicted blocks describe only the exact evaluated scope, not a selected factual answer; cite the block when reporting that state. A factual claim from a selected derived block requires citing its block ID AND the supplied original supporting IDs.

An explicit larger +benchmark allowance leaves production's ten-minute default unchanged and must +be disclosed when comparing arms; a successful 60-minute arm is not a +ten-minute-readiness pass. The allowance is frozen in the run specification and +cannot change on resume. Non-ready checkpoints are never answered. If a +checkpoint wait throws, the runner retains its latest durable status rather +than reporting only the initial pending receipt. +An explicit non-ready checkpoint raises `EKNOWLEDGENOTREADY` and is reported as +`KNOWLEDGE_NOT_READY`, even if a grounding rejection mentions a configured +rubric or provider. Those words alone must not turn a materialization failure +into a missing-endpoint diagnosis; raw evidence remains suppressed in the +sanitized benchmark error. + `longmemeval-live.mjs` runs real production ingestion, retrieval and synthesized answers, followed by model judging. It is separate from the offline preparation CLI and requires `--authorized-live-benchmark`.
