Engine Selection

Available Engine

• fluxrules.engine.phreak.PhreakEngine (the single production engine)

General Guidance

• PHREAK is the de-facto engine for FluxRules; there is no engine to choose.
• Pick an evaluation mode: stateless (default) or streaming (streaming_mode=True).
• Benchmark against your own facts and rule patterns before production rollout.

Note: The simple linear evaluator that backs RuleService is fluxrules.services.reference_evaluator.ReferenceEvaluator. It is a reference implementation of the service EnginePort, not a selectable single-fact engine, and is not available through get_engine().

Engine-Level Evaluation

from fluxrules.engine.phreak import PhreakEngine
from fluxrules.domain.unified_rule import Rule

engine = PhreakEngine()
engine.load_rules([
    Rule(
        id=1,
        name="high_value",
        condition_dsl={"type": "condition", "field": "amount", "op": ">", "value": 1000},
        action="review",
    )
])

result = engine.evaluate({"amount": 1200})
print(result.fired_rules)
