PRO DECISION CONTEXT LOCKED
Public stats remain descriptive. Live probability, price, Action Window, and Decision state are available only after the Pro access check.
No valid movement comparison is available, so Posterior is not inferring one from a small or missing sample.
Completed performance and hot form remain supporting evidence; neither creates a Posterior Decision on its own.
