Egress Bottleneck Default / 通行瓶颈默认

Egress Bottleneck Default fires or arms when a live-floor movement bottleneck is hidden, under-specified, or falsely filed as safe for everyone.

The default is not a panic cutscene. It is the system choosing which flow moves first when the player does not name the physical bottleneck.

Trigger

default_trigger:
  event: storyteller.event.egress_bottleneck_default.v1
  source_card: storyteller.card.live_floor_egress_ledger.v1
  trigger_kind: state_pressure
  breach_kind: ledger_absent | throughput_hidden | protected_flow_hidden | deferred_flow_hidden | support_missing | receipt_missing | future_reader_hidden | universal_safe_exit_claimed | sponsor_tunnel_unfiled | one_way_scar_unrecorded | equivalent
  no_fixed_turn_trigger: true

The event must not trigger from fixed turn count, day/week cadence, chapter quota, raw crowd count, dashboard state, or lens health.

Default narrators

When the player does not choose, one of these narrators must choose for them:

Narrator	Protected by default	Typical harm
security_grid	sealed doors, checkpoint order, sponsor bridge route	access/crowd/claimant flows blocked
safety_marshal	largest visible crowd outflow	proof, performer, or route asset waits
sponsor_tunnel	sponsor package, glamour arrival, private exit	public and access-caption hostility
fan_oxygen_queue	oxygen outflow and public air	camera return, lawful proof, or sponsor route delayed
access_caption_reader	caption-guided accessible exit	silent service move becomes unlawful or hostile
archive_runner	proof bundle or checksum bag	crew and crowd support degrade
blackout_system	dead-air evacuation and powered-door survival	broadcast slot becomes recovery-only
crowd_current	whichever direction is already moving	one-way scar, injury review, or missing witness

Required payload

  counter_deltas_min: 3

Branch consequences

The default must produce one immediate relief or capture, one visible harm or cost, and one future reader mutation. Examples:

• the fan oxygen queue gets out, but a sponsor tunnel claim becomes hostile and the public table demands a receipt;
• the sponsor tunnel moves first, but access-caption readers file a class path scar and fan oxygen resentment rises;
• proof reaches archive, but crew cannot return to the board and a live-floor crew review opens;
• blackout evacuation protects bodies, but the broadcast slot becomes recovery-only and capacity liability reads the dead-air scar.

Failure cases

The event is invalid if it only changes mood, reputation, money, or a generic crowd pressure counter. It must name a default narrator, a protected flow, a harmed/deferred flow, missing inputs, a future reader, and at least three durable deltas.
