From raw movement to a timestamped signal artifact.

The engine watches Tier A sportsbook movement first, then uses Tier B books, exchanges, and prediction markets for confirmation, context, or conflict. A generic consensus move is not treated the same as respected-source movement.

Raw odds changes become movement events only after source freshness, mapping confidence, price direction, line movement, timing, and duplicate suppression are checked.

Signal tiering considers source quality, velocity, confirmation, sport and market rules, key-number sensitivity, prediction-market overlays, and conflict flags.

Every alert preserves the trigger line or price, the current line or price, drift since trigger, and stale context when the market has already moved away from the alert.

Telegram and Discord are planned as delivery channels, but real delivery stays behind explicit kill switches until staging destinations and account rules are configured.

Qualifying signals are checked against closing prices so strong, weak, stale, corrected, and negative outcomes remain part of the record.
