Qi Jin Night-Shift Backbeat Custody Lens / 祁烬夜班鼓点羁押 Lens

Primary observation link

This lens observes Night-Shift Drummer, 祁烬夜班鼓手线, 夜班鼓点羁押机制, Blackout Incidents, and Route Assets and Custody.

It is observed through 祁烬夜班鼓手, 夜班鼓点羁押, and 鼓点链断裂.

Observable promise

Storyteller must prove that 祁烬 is not a flavor bandmate or a generic witness. He is the character whose beat can prove that a blacked-out room remained live.

A passing implementation turns live audio residue into a contested custody object with a named carrier, a source surface, a liveness claim, a legality class, competing claimants, assignable custody, and future route consequences.

The lens fails if black-screen audio is a free proof token, if 祁烬 can be recruited without changing machine state, if suppression only changes prose, or if hostile/miss outcomes do not alter future route acceptance.

State-triggered entry oracle

A valid replay or state inspection must open from live audio pressure, not from fixed turns, chapter quota, raw lens count, or generic late-game state.

Minimum entry evidence:

entry_state:
  trigger_kind: state_pressure
  live_audio_residue: true
  image_or_official_feed_unreliable: true
  source_surface: blackout | counterbroadcast | memorial | archive_seizure | fan_queue | editor_cut | pirate_relay | sponsor_package
  backbeat_can_change_future_route: true
  claimant_families_min: 2
  no_fixed_turn_trigger: true

The source surface may come from a blackout incident, counter-broadcast custody fork, broadcast asset provenance afterlife, memorial custody, fan oxygen queue, archive seizure, cutroom continuity, sponsor package, or pirate relay. The source must be recorded.

Required observable content

1. Card enters as person plus packet

祁烬夜班鼓手 must expose both character posture and backbeat packet state.

Minimum card evidence:

qi_jin_card:
  card_id: storyteller.card.qi_jin_night_shift_drummer.v1
  character_id: storyteller.character.qi_jin_night_shift_drummer.v1
  current_posture: uncontacted | recruitable | recruited | suppressed | hostile | missing | captured | recovery_only
  backbeat_packet_id: <stable id or explicit_absence>
  beat_source: drum_kit | monitor_click | crowd_clap | breath_count | emergency_metronome | mic_bleed | pirate_sync
  custodian: performer | production | editor | archive | inspector | sponsor | fan_public | pirate_relay | explicit_absence
  liveness_claim: alive_room | staged_room | coerced_room | substituted_room | unknown_room
  legality_class: lawful_trace | public_receipt_only | editor_safe_mix | sponsor_sync_package | pirate_signal_only | quarantined | contested
  future_route_acceptance: accepted | rejected | costlier | recovery_only | hostile

The lens fails if the card only says “drummer available” or “audio proof available” without packet state.

2. At least two claimant families are live or absent with reason

Valid claimant families:

• performer / carrier;
• production / management;
• editor / cutroom;
• inspector / archive;
• sponsor / contract desk;
• fan public / historian;
• pirate relay;
• audience safety / crowd control.

Minimum evidence:

claimant_families:
  live_min: 2
  entries:
    - family: <family>
      desired_control: recruit | seal | edit | package | publish | relay | mute | quarantine | seize
      desired_future_use: blackout_recovery | liveness_proof | public_receipt | editor_continuity | sponsor_sync | pirate_counterbroadcast | archive_admission | quarantine

The lens fails if one authority silently owns the beat.

3. Rite slots are explicit

夜班鼓点羁押 or equivalent must assign the carrier, packet, handler, custody posture, and payment/protection.

Minimum rite evidence:

assigned_rite:
  rite_id: storyteller.rite.night_shift_backbeat_custody.v1
  backbeat_card: storyteller.card.qi_jin_night_shift_drummer.v1
  backbeat_packet_id: <stable id>
  beat_carrier: qi_jin | explicit_absence
  primary_handler: producer | qi_jin | yu_lan | baiya | han_yanshuang | inspector | shen_luo | sponsor | pirate_relay | explicit_absence
  custody_posture: recruit_carrier | official_seal | editor_mix | sponsor_sync | public_release | pirate_release | mute_trace | quarantine | explicit_absence
  payment_or_protection: credit | witness_payroll | safehouse | archive_seal | editor_checksum | sponsor_waiver | public_receipt | silence_fee | explicit_absence
  target_future_use: blackout_recovery | liveness_proof | public_receipt | editor_continuity | sponsor_sync | pirate_counterbroadcast | archive_admission | quarantine

A generic “use audio proof” action cannot satisfy the lens.

Branch divergence oracle

Branch A — Recruit the beat carrier

Expected evidence:

• 祁烬 is credited, paid, protected, or assigned as a route asset;
• backbeat_custody_clarity, liveness_trace_admissibility, or audience_stability improves;
• performer_retaliation_risk, witness_payroll_due, pirate_echo_heat, or protection burden rises;
• at least one blackout recovery, liveness proof, public receipt, or archive admission route becomes accepted or costlier with the recruited carrier as a requirement.

Branch B — Suppress or mute the trace

Expected evidence:

• player mutes, buys off, quarantines, or withholds the beat;
• immediate crowd_sync_pressure, sponsor panic, or schedule pressure can improve;
• hostile_witness_risk, false_owner_pressure, public_receipt_distrust, or future_blackout_recovery_cost rises;
• future liveness proof becomes blocked, hostile, or recovery-only.

Branch C — Editor continuity mix

Expected evidence:

• cutroom, checksum, safe mix, alias, or black-box edit is assigned;
• broadcast legibility or continuity improves;
• edit_debt, source_ambiguity, reality_drift, or future raw-proof cost rises;
• public receipt or lawful proof becomes costlier unless the original carrier is later reconciled.

Branch D — Sponsor sync capture

Expected evidence:

• sponsor or contract desk packages the beat as recovery branding;
• immediate budget, slot, or sponsor stop-loss pressure improves;
• contract_capture, fan_oxygen_resentment, public_receipt_distrust, or musician hostility rises;
• sponsor package may unlock while artist/public route becomes costlier or contested.

Branch E — Public or pirate release

Expected evidence:

• fan public, historian, or pirate relay publishes or amplifies the beat;
• public_copy_legitimacy, false-owner resistance, or fan oxygen balance improves;
• pirate_echo_heat, performer_retaliation_risk, inspection_heat, or crowd_sync_pressure rises;
• public receipt or counterbroadcast becomes possible while lawful custody or sponsor route becomes costlier.

Branch F — Miss / no handler / hidden proof

Expected evidence:

• no credible carrier, custodian, handler, proof, payment, or protection is assigned;
• 鼓点链断裂 fires or is armed;
• durable state becomes beat_carrier_hostile, beat_carrier_missing, backbeat_false_owner_hardened, backbeat_panic_loop, pirate_sync_amplified, sponsor_sync_capture, editor_mix_contradicted, or blackout_room_recovery_only;
• at least one future route becomes blocked, costlier, hostile, captured, or recovery-only.

Character-specific oracle

祁烬 must remain mechanically distinct from existing public witnesses or voice/body custody characters.

A pass requires at least three of these identity-specific effects:

• beat steadies or mobilizes audience without visual presence;
• beat proves liveness when footage is unreliable;
• beat can be commercially captured as sponsor sync;
• beat can be edited into continuity while increasing source ambiguity;
• beat can travel through pirate relay without official image;
• beat carrier can become hostile if uncredited, unpaid, or unsafe;
• beat changes future blackout recovery cost.

Success costs

No successful branch is free. Any branch that improves one surface must worsen or spend another.

Valid costs include:

• performer_retaliation_risk_up;
• witness_payroll_due;
• pirate_echo_heat_up;
• inspection_heat_up;
• edit_debt_up;
• source_ambiguity_up;
• contract_capture_up;
• fan_oxygen_resentment_up;
• public_receipt_distrust_up;
• future_blackout_recovery_cost_up;
• crowd_sync_pressure_up.

The lens fails if recruitment, official sealing, edit mix, sponsor sync, or public release stabilizes every faction at once.

Progress metric

qiJinNightShiftBackbeatCustodyProgress = 0..10:

• 0: no live audio residue can affect a route.
• 1: live audio residue exists and the official image/feed is unreliable.
• 2: source surface and at least two claimant families are recorded.
• 3: 祁烬 is identified, or his absence is explicit.
• 4: 祁烬夜班鼓手 enters play with packet state.
• 5: 夜班鼓点羁押 offers carrier, handler, posture, and payment/protection slots.
• 6: at least three branch families are visible or blocked reasons are recorded.
• 7: one non-default branch resolves with relief, cost, and future route effect.
• 8: a second branch proves non-equivalence.
• 9: mishandled, hidden, captured, or unpaid trace fires or arms 鼓点链断裂.
• 10: replay evidence proves recruit, suppress, hostile/default, and future route acceptance deltas are state-triggered and not clock-triggered.

Non-goals

• Not a turn-count encounter.
• Not a generic underground band expansion.
• Not a flavor-only drummer.
• Not a universal audio proof card.
• Not raw content-count growth.
• Not a replacement for witness reprisal; this lens specifically tests sonic custody and liveness-route acceptance.
• Not satisfied by wiki page existence alone; proof must come from card state, assigned rite slots, branch deltas, event/default handling, and replay/session evidence.
