"""Backward-compatible facade for precheck internals.

The reusable implementation has been split into smaller modules:
- precheck_constants  : paths and thresholds
- time_utils          : UTC/local time helpers
- data_utils          : json, hash, float, symbol normalization
- state_manager       : load/save/sanitize state
- market_data         : exchange, ohlcv, metrics
- candidate_scoring   : top candidate selection
- snapshot_builder    : build_snapshot
- adaptive_profile    : trigger profile builder
- trigger_analyzer    : analyze_trigger

Keep this module importable so older entrypoints continue to work.
