"""Tracking modules for cross-frame state management.

This package contains components that track state across multiple frames
to identify play boundaries and other temporal events.

Architecture (v2 - Restructured):
- PlayTracker: Parent coordinator that manages sub-trackers
- NormalPlayTracker: Handles standard plays (clock reset to 40, countdown)
- SpecialPlayTracker: Handles 40→25 transitions (timeouts, punts, FGs, XPs)
- FlagTracker: Independently tracks FLAG (penalty) events

Public API:
- TrackPlayState: Main state machine for play tracking (facade, backward compatible)
- PlayTracker: New parent tracker class (can be used directly)
- FlagTracker: Independent FLAG event tracker
- PlayMerger: Merges overlapping plays
- ClockResetIdentifier: Post-hoc analysis of 40→25 clock resets
- Models: PlayEvent, PlayState, TrackerMode, determine_timeout_team, etc.

Internal modules:
- normal_play_tracker: Normal play handling logic
- special_play_tracker: Special play (40→25) handling logic
