Oracle assertions

Valid custody branch:

1. Source is storyteller, turn is 31, and restartAdvanced === false.
2. Current hand contains the continuity/archive anchor set.
3. archiveCustody.claimContinuity is legal with archive table, casefile, safe version, double archive, and audience signature anchors.
4. Dry-run emits a continuity claim event, custodies the black-box fragment, raises archive-custody, and leaves 郁蓝 as witness / custody contact / recruit candidate without auto-recruiting her.

Miss branch:

1. archiveCustody.pirateLoop without an authority anchor emits a miss / pirate-loop event.
2. Miss branch increments system-pressure by 1..3, does not destroy 第七穹顶连续性案卷, and does not advance restart.
3. Within 30 turns the case remains visible or reaches a named storyteller terminal state.
