+## [0.11.7] — 2026-04-28 · Default tab → Sources, fix sort-reset on reload
+
+Two small UX defaults that were quietly wrong.
+
+### Changed
+- **Default tab on first load is now Sources** (was Measures). Sources is the highest-leverage entry point for someone documenting an unfamiliar PBIP — it answers "where does this data come from?" before "what calculations does it do?". Measures is one click away.
+- **`switchTab("sources")` on report reload** — was previously `switchTab("measures")`, so swapping reports always dropped you on Measures regardless of the initial-load default.
+
+### Fixed
+- **Reload no longer flips Measures + Columns to ascending sort.** The cross-report state-reset at `__loadBrowserData` was setting `desc: false` while preserving the sort key — so the initial-load default (`usageCount` descending: busiest measures first) flipped to ascending on every report swap. Now explicitly re-applies `{ key: "usageCount", desc: true }` for both measures and columns on reload, matching the initial render.
+
+### Notes
+- Sort default for Measures and Columns has always been "Used (desc)" on first load — this release just makes reload behave the same way.
+- No new tests; the bug was in initial-state setup, not in any pure function.
