 # Changelog
 
+## [1.37.29] — 2026-08-26
+
+The chart range selector said points and meant days. Someone who weighs in twice a week picked "7 pts", saw two, and reasonably concluded the chart was broken.
+
+### Fixed
+
+- The range tabs now say what they do: 7d / 30d / 90d / All, in every locale. The selector has always fetched a calendar-day window; only the labels claimed a point count. Anyone measuring less than daily saw fewer points than the tab promised and had no way to know the tab was the lying part.
+- The "All" view no longer serves monthly means under a weekly-average caption. The server picked the aggregation tier from the requested window — and "All" always requests ten years — so every record came back in monthly buckets no matter how short its history, while the chart captioned the series from the real span. A four-month record showed four points labelled "Weekly avg". The tier now follows the span the data actually covers, and a test pins the server tier against the caption ladder for every span up to ten years so the two cannot drift apart again.
+- The same tab no longer means two different things depending on how the chart mounted. On the dashboard's preloaded data the old code showed "the last N readings" reaching arbitrarily far back; on a directly opened chart it showed a day window. Both paths now filter to the same calendar-day window, which also keeps comparison-overlay shadow data from leaking into the visible range on sparse records.
+- The mood chart windows by days like every other chart. It used to slice the last N logged days out of the whole history, so its "7" could span weeks while the weight chart's "7" meant a week.
+- The aggregation chip in the chart header reads the same grain decision the chart and its data table use, instead of re-deriving it separately.

 ## [1.37.28] — 2026-08-24
 
 Eleven parts of a shared record were selectable and invisible. Ticking one and sending the link showed the recipient nothing, while the same link's PDF download carried it.
