…ed rows in FetchGroupedPlansAsync, the first root row is recursively expanded to the deepest level so the user immediately sees the full hierarchy. 2. Load child plans (LoadHighlightedPlan_Click / LoadSelected_Click / CollectLeafPlans): • "Load Plan" on a grouped row (QueryHash, PlanHash, or Module level) now recursively collects all descendant leaf plans where both PlanId > 0 and QueryId > 0 • Rows with PlanId == 0 or QueryId == 0 are never loaded • "Load Selected" does the same expansion for each selected row 3. Golden headers (ApplyGroupByHeaderColors): • When GroupBy=QueryHash: "Query Hash" and "Plan Hash" column headers get gold (#FFD700) foreground • When GroupBy=Module: "Module" and "Query Hash" column headers get gold • When GroupBy=None: all header colors are reset to default 4. Column reorder (ReorderColumnsForGroupBy): • QueryId and PlanId columns are now pushed after the GroupBy key columns • QueryHash mode: Expand → Checkbox → QueryHash → PlanHash → QueryId → PlanId → rest • Module mode: Expand → Checkbox → Module → QueryHash → QueryId → PlanId → rest • None mode: original column order is fully restored

…ediate row, the code now picks the QueryText from the top representative leaf row (the one with IsTopRepresentative == true, falling back to the first available leaf) and assigns it to the parent's QueryStorePlan.QueryText. This is done at two levels: 1. Intermediate rows (PlanHash in QueryHash mode, QueryHash in Module mode): Gets the query text from the top representative leaf within that specific group. 2. Root rows (QueryHash level, Module level): Gets the query text from the top representative leaf across all leaves in that root group. No additional database queries are made — the text comes entirely from grouped.LeafRows which was already fetched.
…alongside GridLoadingOverlay.IsVisible = true at the start of every fetch, so any lingering empty message is dismissed before the next request. 2. FetchGroupedPlansAsync — When IntermediateRows.Count == 0 and the mode is Module: sets the message text to "No module found in the selected period", shows the overlay, and returns — without writing to StatusText. For QueryHash mode (or any other non-Module grouped mode) that still hits the empty case, the original status bar message is preserved.

… grouped fetches The Step 3 ranked CTEs in both FetchGroupedByQueryHashAsync and FetchGroupedByModuleAsync joined sys.query_store_query_text without using any of its columns — the actual text fetch happens in the Final select. Also fixes tab/space inconsistency in the doc comment blocks for both methods. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…leanup Remove unnecessary query_store_query_text joins in grouped fetches
- Add page_views table and POST /api/event endpoint for lightweight page view tracking (visitor hash from IP+UA+date, no PII stored) - Expand GET /api/stats to return traffic data (views, visitors, referrers) alongside sharing stats - Add analytics JS snippet to web app index.html - Add Plan Analyzer tab to stats dashboard (dashboard.html) - Auto-cleanup page views older than 90 days Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
