Environment variables

NameRequiredNotes
OTGATE_BACKENDOptionalBackend to gate: 'fake' for the bundled in-memory reactor simulator, 'asyncua' for a real OPC UA server. Start with 'fake' — it needs no plant and no extra dependency.
OTGATE_POLICYOptionalPath to the policy YAML. Any tag not listed in it is denied by default.
OTGATE_AUDITOptionalPath to the append-only JSONL audit log. Every call, allowed or not, produces exactly one line.
OTGATE_SHADOWOptionalSet to 1 to run in shadow mode: allowed writes are recorded as 'WOULD execute' and never reach the backend. Use this to watch an agent for a while before letting it touch anything.
OTGATE_RATE_HISTORYOptionalPath to a JSONL file that keeps the rate-of-change time base across restarts. Without it a restart loses the time base, and rate limits fall back to a one-interval allowance.
OTGATE_OPCUA_ENDPOINTOptionalOPC UA endpoint, e.g. opc.tcp://localhost:4840. Required when OTGATE_BACKEND=asyncua.
