Lin Xi Future Broadcast Witness / 林夕未来广播见证机制

Lin Xi Future Broadcast Witness is the character-route mechanism that makes a future broadcast require an accountable witness boundary before it can change black-box, route, ending, or broadcast-reality state.

The mechanism converts an old seed condition into playable management/RPG pressure:

• the signal is not a clean flag;
• Lin Xi is not a lore unlock;
• the black box is not opened by hearing one future line;
• every witness branch changes a future reader.

Content objects

• 林夕未来广播案卷 records the signal, contradiction surface, Lin Xi reachability, reader, excluded reader, handler, proof bridge, and future effect.
• 林夕信号问询 assigns the witness boundary through interview, echo, checksum, quarantine, silence, route ally, or default.
• 林夕信号抹除默认 hardens when a future signal is consumed while Lin Xi’s witness state is missing or falsely clean.

Branch contract

Every branch must mutate at least three surfaces:

1. Lin Xi encounter or witness state;
2. signal or black-box contradiction state;
3. future reader, route, ending, or broadcast-reality state.

Branch	Immediate relief	Cost/scar	Future effect
Private interview	witness preserved; lead narrowed	handler burden; public receipt absent	private-only; public addendum required
Public echo	archive capture falls; contradiction visible	witness exposure; sponsor pressure; inspection heat	public-only; lawful checksum required
Lawful checksum	proof chain improves; false summary blocked	archive debt; edit debt; public distrust	lawful-only; black-box route costlier
Archive quarantine	source integrity preserved; exposure falls	route delay; archive debt; ending pressure	quarantined; recovery-only until reproof
Sponsor silence	slot or report pressure falls	false absence; sponsor capture; reader hostility	sponsor-only; default armed
Recruit route ally	narrow black-box route opens	protection debt; license pressure; ending scar	route ally; accepted with witness cost
Erasure default	immediate assignment pressure falls	signal erased; hostile future reader; drift rises	blocked, recovery-only, or reproof required

Missability and recruitability

Lin Xi must have separate encounter, witness, and recruitment states.

missability:
  encounter_state_can_be_missed: true
  witness_state_can_be_false_absence: true
  recruit_window_can_close: true
  recovery_after_miss_requires_scar: true
recruitability:
  recruit_kind: route_ally
  not_global_follower: true
  route_ally_requires_witness_boundary: true
  route_ally_cannot_clean_black_box: true

Valid miss states:

• missed_before_interview;
• false_absence_filed;
• sponsor_silenced;
• archive_quarantined_unreleased;
• hostile_future_reader;
• recovery_only_contact.

Valid recovery states:

• reopen interview with handler burden;
• public echo with witness exposure;
• lawful checksum with archive/edit debt;
• route ally with protection debt;
• hostile future reader with contradiction-pending route.

Integration rules

• With 白鸦黑箱补丁羁押线, Baiya may provide checksum but cannot turn Lin Xi into clean archive proof.
• With 播出实在漂移审计, a contradicted future signal can raise drift unless a reader-scoped witness state exists.
• With 连续性后用藐视线, official versions cannot cite Lin Xi’s absence unless the absence state was assigned.
• With 播出资产来源后生线, a future signal tied to one copy cannot prove every future copy.
• With 结局伤痕账本线, the black-box ending can inherit Lin Xi’s witness scar instead of accepting a clean unlock.

• Not a fame threshold unlock.
• Not a prophecy cutscene.
• Not a universal black-box key.
• Not valid unless Lin Xi’s witness boundary changes future playable state.
