+## Evidence

+- Source visual truth: `/var/folders/yx/cq4gbk4x6w702x_slllw80mw0000gn/T/TemporaryItems/NSIRD_screencaptureui_SnOJSi/截屏2026-08-20 09.27.50.png`.
+- Source dimensions: 2974 x 228 px toolbar crop captured from the existing desktop page.
+- Implementation route: `http://127.0.0.1:54535/admin/schedule`.
+- Implementation screenshot: `/Users/mac/.codex/visualizations/2026/08/18/01a0129d-4374-7200-b8f1-0c65ae6eebc9/schedule-search-audit/08-toolbar-after-refine.png`.
+- Implementation viewport and dimensions: 1792 x 1064 CSS px at the browser capture density.
+- State: authenticated operations administrator, day view, historical date `2024-07-20`, all coaches selected, latest-data shortcut visible.
+- Density normalization: the source is a high-density focused toolbar crop while the implementation is a full-page browser capture. The same toolbar state was opened together for a focused structural comparison; pixel-identical scaling was not used because the requested result intentionally changes the source proportions.
+
+## Full-View Comparison
+
+- The shortened coach selector leaves a clear flexible gap before the latest-data shortcut and removes the visually dominant full-width dropdown.
+- The toolbar remains a single row at the verified desktop viewport and preserves the existing page hierarchy, summary cards, and schedule lanes.
+- The latest-data shortcut stays right-aligned and all existing interactions remain available.
+
+## Focused Comparison
+
+- The source crop and implementation screenshot were opened together in one comparison input.
+- The day/week/list switcher, previous button, date input, next button, coach selector, and latest-data button now share a 44 px control height.
+- The coach selector is capped at 360 px on wide screens, reduces to a flexible 340 px maximum below 1300 px, and becomes full-width below 700 px.
+
+## Findings
+
+- No actionable P0, P1, or P2 differences remain for the requested changes.
+- Typography: existing application font, weight, labels, and hierarchy are preserved; no wrapping or truncation was introduced.
+- Spacing and layout: the oversized coach-filter track was replaced with a bounded control while retaining 12 px toolbar gaps and bottom alignment.
+- Colors and tokens: existing border, surface, focus, and brand-green tokens are unchanged.
+- Image quality and assets: this toolbar contains no raster imagery or custom decorative assets; existing Lucide interface icons remain sharp.
+- Copy and content: all operational labels and values are unchanged.
+
+## Comparison History
+
+1. Source finding: the coach dropdown consumed nearly all remaining horizontal space and the control heights appeared inconsistent.
+2. Fix: added dedicated `coach-filter` and `latest-data` layout classes, capped the filter width, and normalized interactive controls to 44 px.
+3. Post-fix evidence: the implementation screenshot shows a compact selector, consistent control heights, preserved right alignment, and no desktop overflow.
+
+## Follow-up Polish
+
+- No additional P3 changes are needed for this focused request.
