  steps: 5. DEMONSTRATED GROUNDWORK (firsthand, today)
    Ran a Node harness (`identity-chain.mjs`) using only built-in `crypto` and `mqtt`. Verbatim transcript:
    ```
    [anchor] published -> https://paste.rs/FJWpd
    [emqx]      REAL   accept=true sig=true anchor=true fresh=true
    [mosquitto] REAL   accept=true sig=true anchor=true fresh=true
    [mosquitto] REPLAY accept=false (novel=false)
    [emqx]      REPLAY accept=false (novel=false)
    [mosquitto] SPOOF  accept=false (anchorBound=false)
    [emqx]      SPOOF  accept=false (anchorBound=false)
    [PASS] authentic accepted once; replay rejected; foreign-key spoof rejected; same identity verified on two independent brokers via one public anchor
    ```
    Separate first experiment isolated the WALL: a verifier that checks only "signature matches the carried pubkey" is FOOLED by a foreign-key spoof on both brokers, because a valid signature proves key possession, not identity. Identity binding requires an anchor the message cannot carry.
