Live Floor Egress Ledger / 直播现场通行瓶颈账本

Live Floor Egress Ledger records a concrete movement bottleneck on the Seventh Dome live floor. It exists for the moment when a door can be open, a room can be assigned, and power can be allocated, but the actual human flow still cannot move cleanly both ways.

The card turns egress into a playable surface: who moves, which node or corridor carries them, which flow is protected, which flow is deferred, what support is missing, and which future reader consumes the scar.

Card promise

This card must not mean evacuation happens. It must name the bottleneck.

A valid row shows:

Required separations

• access_state is not enough. A route can be open and still jammed.
• room_occupancy is not enough. The room can be assigned while the path to it is blocked.
• emergency_power is not enough. Powered doors and lights do not choose which crowd moves.
• caption_notice is not enough. Accessible routing must still have a physical path and support.
• broadcast schedule is not enough. A live slot cannot silently absorb blocked bodies.

Common live-floor rows

Row	Protected flow	Deferred flow	Likely scar
Fan gate oxygen outflow	fan oxygen queue reaches air	sponsor arrivals or camera return	sponsor pressure, public safety legitimacy
Accessible caption-guided exit	access-caption readers receive signed path	silent service corridor move	schedule pressure, security heat
Proof escort through corridor	archive proof or route asset leaves safely	crew return to board	crew hazard, edit delay
Performer stage withdrawal	artist exits camera line safely	public claimant table enters late	public distrust, recovery-only claim
Witness quiet move	protected witness avoids crowd camera	fan public queue is held	fan resentment, lawful-only witness route
Sponsor tunnel claim	sponsor package moves first	public/accessible exit deferred	access violation, public hostility, sponsor capture

Counters and states

Valid relief deltas include egress_harm_risk_down, public_safety_legitimacy_up, proof_route_preserved, performer_exposure_down, witness_exposure_down, access_route_certified, and oxygen_harm_risk_down.

Valid cost deltas include crowd_pressure_up, access_caption_pressure_up, fan_oxygen_resentment_up, sponsor_stop_loss_pressure_up, security_heat_up, crew_hazard_up, schedule_pressure_up, route_asset_wear_up, proof_contamination_risk_up, and handler_burden_up.

Valid future states include egress_receipt_required, deferred_flow_hostile, accessible_exit_public_only, sponsor_tunnel_capture, corridor_one_way_scar, crowd_crush_review, proof_escort_costlier, stage_threshold_recovery_only, and broadcast_capacity_scarred.

Failures

The card is invalid if it only records a crowd mood, a generic evacuation order, an abstract capacity number, a fixed turn alarm, or an all-clear result. At least one real flow must lose time, support, access, route quality, or future legitimacy.
