Force Threshold Alarm
NM19 (F = ma) on every reading: idle → watching → alert when computed force crosses your limit. The classic structural-load watchdog.

Operators it composes
Each transition fires a registry operator through the master equation (compute → prove → verify). This template composes:
NM19KO42
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/force-threshold-alarm
# 2. Deploy onto your machine (auth: session; body carries your machine slug)
curl -sS -X POST https://zeqsdk.com/api/contracts/templates/force-threshold-alarm/deploy \
-H "Content-Type: application/json" \
-b "<your session cookie>" \
-d '{"slug":"<your-machine>"}'
# → 201 { "ok": true, "contract": { "id": "…", "currentState": "idle", … },
# "template_id": "force-threshold-alarm" }
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.
