-- Candidate combination, dominance, and reconciliation (`combine_candidate_intent_records`)
-- Policy admission **mechanism** when `CorePolicyAdmissionContext` is provided
-- Execution Control plan/apply **mechanism** when policy + apply contexts are provided
-- `CoreStepResult` / `CoreStepDecision` production
-
-### Externally supplied extension points
-
-- **Strategy evaluator** — `CoreStepStrategyEvaluator` or `CoreWakeupStrategyEvaluator`
-- **Policy evaluator** — any object implementing `PolicyIntentEvaluator` (passed via `CorePolicyAdmissionContext`)
-- **Execution Control** — `ExecutionControl` instance (passed via `CoreExecutionControlApplyContext`)
-- **Configuration** — optional `CoreConfiguration` for positioned market reduction
-- **Event bus** — `StrategyState` requires an `EventBus`; use `NullEventBus` for standalone Core/tests
-
-### Convenience implementations (optional; not wired by default)
-
-- **Risk Engine** (`RiskEngine`) — provided `PolicyIntentEvaluator` with built-in policy gates
-- **`ExecutionControl`** — provided queue/rate/inflight implementation
-- **`NullEventBus`** — discards observability events for tests and examples
-
-The minimal quickstart uses an inline allow-all policy to stay small. That does
-**not** mean the Risk Engine is unused or dead. Use `RiskEngine` when you want the
-built-in Risk Engine policy behavior. See `examples/core_step_quickstart.py` (minimal) and
-`examples/core_step_with_risk_engine.py` (Risk Engine variant).
