Julian Pawlowski 8f05f8cac7 perf(interval_pool): hoist fetch_groups and precompute period criteria ... - Move UTC import from inline (inside _has_real_gaps_in_range) to module-level in manager.py - Hoist get_fetch_groups() out of while loop in _get_cached_intervals: eliminates ~384 function calls per invocation - Pre-compute criteria_by_day dict in build_periods before the for-loop: eliminates ~381 redundant NamedTuple constructions per call; only ref_price/avg_price vary by day (max 3 entries), flex/min_distance/ reverse_sort are constant throughout Impact: Reduces unnecessary object creation during the hot paths called every 15 minutes and during all relaxation phases.		2026-04-06 14:35:33 +00:00
