//! V06 daily-to-weekly/monthly sums, weighted 18% ratio, distinct sessions and partial-period flags.

//! Do not average daily percentages or sum daily distinct counts.

/// Weekly/monthly sums agree; weighted cross-day ratio is 18%, unlike the 50% daily-percentage average.

// Day one: input 100/cache read 90; day two: input 900/cache read 90.

// Daily ratios are 90% and 10%.

// Recalculate from summed values: 180/1000 = 18%.

/// Zero denominator yields no valid ratio, displayed as — rather than 0%.

// Fields are known but the denominator is zero.

/// One session over two days counts once weekly; another session brings the total to two.

// Weekly DISTINCT is two, unlike the daily-count sum 1+2=3.

/// Current week is in progress; the earliest retention-truncated week has partial history.

// ISO week 2026-W32.

// ISO week 2026-W39.

// Thursday.

// Retention cutoff: periods before August 20 have truncated history.

// Today remains inside this week.

// A completed period is not in progress.
