Prompt Desk Lamp Pull-Chain Mechanics
The lens uses a state-pressure entry: prompt-desk lamp chain visible, page-margin shadow visible, clean prompt conflict visible, blackout cue window visible, protected understudy or explicit absence visible, recovery method visible, custodian visible, and future reader named. It forbids fixed-turn, raw-count, dashboard-health, or generic lens triggers.
Each branch must emit a distinct lamp state, future route duty, and at least three counter deltas while denying lighting safety clearance, performer consent, archive ownership, memorial authority, and universal broadcast permission.
