2026-07-16Fix overlapping-event double-subtraction in ComputeBudgetPeriod; clarify ↵Peter Stone
task-filter doc comment; add multi-day test Overlapping calendar events within the same availability block were each subtracted independently, double-counting their intersection and making availability under-counted (a 120-min block with two 60-min-overlap events that overlap each other 18:30-19:00 came out to 0 min instead of the correct 30 min). Replace the per-event overlapMinutes subtraction with busyMinutesInBlock, which clips each event to the block, merges the clipped intervals, and subtracts the union's total length. Also clarify ComputeBudgetPeriod's doc comment: task filtering only enforces an upper bound (due < end); start is intentionally not used to filter tasks, since callers are expected to pre-fetch and pass in already-overdue tasks. Add a multi-day-window test verifying availability sums correctly across days, a block only contributes on its matching weekday, and the day-iteration loop excludes the day at `end`.

2026-07-16Add pure availability-minus-events and scheduled-load computationPeter Stone
ComputeBudgetPeriod is a standalone, dependency-free function over in-memory availability blocks, calendar events, and tasks: sums weekly availability minus overlapping calendar events for [start, end), and sums estimated minutes for tracked, incomplete tasks due in that window.
