Panic Button

Press. Count down. Cancel, or go quiet. Credentials live on this device and travel in the request body only — never the URL.

VPN tripwire

Off — watches the network path while this page stays open. A changed route trips the leash.

Proximity + token (opt-in hardening)

Off — a BLE phone link or a plugged USB token vouches while this page stays open.

Pair this device

Paste the holder id + secret from whoever armed the leash (shown once, out of band). Stored on this device only.

Holder id Secret

Never:engages without the secret. A stranger with this page and no pairing can do nothing. Cancelling writes a cancel note to the leash audit — a coerced cancel leaves a trace.
