docs(#36): rig live gate PASS (two runs, reset echo held 751 ms on run 2); seed retargeted to String nodes; register row 120 — OPC UA scalar writes go out as String variants

# * Payload (Double) <- ns=3;s=Motor.Speed writable, NOT simulated

# * Complete (String) <- ns=3;s=JoeAppEngine.BTCS writable, NOT simulated
# * Handshake (Call) — the reset-aware overload; returns the HandshakeResult fields
# * Device (ValueChange on Trigger) — plays the PLC: on Trigger==true sets Complete=true
# * Device (ValueChange on Trigger) — plays the PLC: on Trigger=="True" sets Complete="True"
# and clears Trigger (so the next run's trigger is a fresh edge)
#
# WHY STRING NODES, NOT THE Boolean/Double ones (Motor.Running, Pump.Running, Motor.Speed):
# a data-sourced SCALAR write leaves the InstanceActor as its codec-encoded STRING ("True",
# "42.5") and RealOpcUaClient wraps it in a plain Variant, so opc-plc answers BadTypeMismatch
# (0x80740000) for every non-String node — observed live 2026-09-10 (deferred-work register
# row 120). Only List values are decoded before the write. The two String nodes above are
# the rig's only writable String scalars, so the flags are the strings "True"/"False";
# the reset-echo ordering this gate proves is identical either way.
# - Instance handshake-demo-1, bound + deployed

# Not idempotent (names must be unique). To re-seed:
