Tunneling Probability Gate
QM8 (T ∝ e^{−2∫√(2m(V−E))/ℏ² dx}): the gate opens only when computed transmission probability clears your threshold.

Operators it composes
Each transition fires a registry operator through the master equation (compute → prove → verify). This template composes:
QM8
Browse the operators at /operators/; the building blocks a transition calls are the framework's protocols. KO42 is the always-on substrate operator; physics operators carry proof_required: true, so each fire runs the full compute → prove → verify path and lands a verifiable proof digest on your entangled state.
Deploy it
Inspect the full definition, then deploy it onto your state machine. Every fire is Zeqond-stamped onto your entangled state.
# 1. Inspect — the full definition (states, transitions, operators) as served
curl -sS https://zeqsdk.com/api/contracts/templates/tunneling-probability-gate
# 2. Deploy onto your machine (auth: session; body carries your machine slug)
curl -sS -X POST https://zeqsdk.com/api/contracts/templates/tunneling-probability-gate/deploy \
-H "Content-Type: application/json" \
-b "<your session cookie>" \
-d '{"slug":"<your-machine>"}'
# → 201 { "ok": true, "contract": { "id": "…", "currentState": "closed", … },
# "template_id": "tunneling-probability-gate" }
The deploy path runs the same two-stage validation as the canonical create route (ContractDefinitionSchema.parse + validateContractDefinition against the live registry), writes the creation row onto your entangled state, and schedules the first fire. From there, drive transitions with POST /api/chain/<your-machine>/contracts/<id>/transition or let any triggers fire them autonomously.
