  Topic: ERR_REPLAY_DETECTED (Error Code: 0x0004)

  Description:
    This error occurs when a receiving KSP endpoint detects a packet sequence
    number that has either already been processed or falls completely behind the
    current sliding replay protection window (1024 packets).

  Why it happens:
    1. A malicious attacker is replaying intercepted wire frames.
    2. Extreme network packet reordering across multiple ISP hops.
    3. Sequence counter desynchronization between client and server.

  How to resolve:
    - If testing over lossy networks, increase window via `ksp config --window 2048`.
    - If persistent, execute `ksp session reset` to renegotiate fresh keys.
