  core_statement: >
    ReceiverOS is the final defence audit layer. It identifies the human,
    institutional, digital or living-world node where shock actually lands,
    then checks whether the receiver survived, understood, remained calm,
    avoided falsehood, received repair and became stronger for the next shock.

    - "Who or what received the shock?"

      meaning: "Shock is absorbed, translated or buffered."
    stressed:
      meaning: "Receiver is under pressure but remains functional with support."
    damaged:
      meaning: "Receiver has suffered real loss and needs direct repair."
    broken:
      meaning: "Receiver cannot continue normal function without major rescue or replacement."

  receiver_audit:
    fields:
      alive: "Did the receiver survive physically or structurally?"
      clear: "Did the receiver understand?"
      calm: "Was fear kept below collapse level?"
      connected: "Was the receiver connected to help and information?"
      truthful: "Was false reality blocked or corrected?"
      functional: "Could the receiver continue basic operation?"
      repairable: "Can damage be repaired before it compounds?"
      strengthened: "Did the receiver become better prepared for next time?"

  failure_condition:
    formula: "ShockLoad > ReceiverStrength + BufferSupport + RepairRate"
    meaning: "The receiver breaks when shock exceeds capacity, support and repair."
  success_condition:
    formula: "ReceiverStrength + BufferSupport + RepairRate >= ShockLoad"
    meaning: "The receiver survives when capability, support and repair absorb the shock."
  final_output_rule:
    statement: >
      Every DefenceOS report should end by asking:
      who or what received the shock, what condition is the receiver in,
      what repair has begun, and what memory must update before the next shock.
  final_line: >
    Defence is complete only when the final receiver survives the shock,
    understands reality, remains connected to repair and becomes stronger for the next impact.
