  "_comment": "The REVIEW artifact for a MISS: the SAME declared view as context-view-resident.json, but source_digest_now is ABSENT — the span was elided from the resident set (paged out). This is NOT a loss and NOT a fabrication: the bytes still live in the append-only log, so the check returns a demand-page FAULT token (SOURCE_PAGED_OUT). The caller pages the span back in through the gate and re-checks (cf. ctxplan.DemandPage / Fault, 'a forecast MISS costs one demand-page, never a lost fact'). The optimization lens: a planned working set may safely drop this span precisely because a miss is recoverable.",
