+# Middle Rounding And Snap Angle UI Verification
+
+PR: PR_26133_084-fix-actual-middle-rounding-and-snap-angle-rotate-ui
+
+## Status
+
+- PASS: middle/interior point rounding visibly changes rendered geometry.
+- PASS: Snap Angle Rotate uses constrained dropdown controls when enabled.
+
+## Middle/Interior Rounding
+
+- Verified polygon point rows still have one rounding checkbox per row.
+- Verified checking point 2 changes the rendered polygon from a straight `polygon` to a rendered `path` with a quadratic `Q` curve.
+- Verified checking point 3 adds a second independent `Q` curve.
+- Verified unchecking point 2 leaves point 3 rounded and point 2 square.
+- Verified polyline middle points use the same rendered `path` + `Q` curve behavior.
+- Verified start/end rounding remains covered by independent arc endpoint checks.
+- Verified `[+]` still copies and inserts a point after the current row.
+- Verified trash still deletes only that row and keeps schema minimum-point guards.
+
+## Snap Angle Rotate UI
+
+- Verified Snap Angle disabled:
+  - numeric Rotate textbox enabled
+  - Rotate dropdown disabled
+  - Snap Angle Step selector disabled
+- Verified Snap Angle enabled:
+  - numeric Rotate textbox disabled
+  - Rotate dropdown enabled
+  - Snap Angle Step selector enabled
+- Verified default Step `15` dropdown values:
+  - `0, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315, 330, 345`
+- Verified Step `45` dropdown values:
+  - `0, 45, 90, 135, 180, 225, 270, 315`
+- Verified selecting `45` from the dropdown rotates the selected shape by `45` degrees.
+- Verified disabling Snap Angle restores raw numeric rotation input; entering `-30` applies the raw delta.
+
+## Validation
+
+- PASS: npm run test:workspace-v2
+- Result: 54 passed
+- Console/runtime errors: none observed in the exercised Object Vector Studio V2 flows.

 - Shape Geometry point rows still render exactly one Round checkbox per point row.
 - Row-local plus buttons still insert a copied point directly after the current row.
 - Row-local trash buttons still delete only their row and reject invalid minimum-count deletion.
-- Polygon interior point rounding now verifies two rounded middle/corner points, then unrounds one and confirms the other stays rounded.
-- Polyline middle point rounding still verifies independent middle-joint round/unround behavior.
-- Arc start/end rounding still verifies independent endpoint controls.
-- Snap Angle Rotate is explicitly verified with Snap Angle enabled: Rotate input 22 applies 15 degrees using the current 15 degree snap increment.
-- Snap Angle disabled still applies the raw entered rotation delta.
+- Polygon and polyline middle/interior rounding now verifies actual rendered SVG geometry changes to a path with quadratic `Q` corner curves.
+- Checking two middle/interior points, then unchecking one, keeps the other rendered as the only rounded joint.
+- Start/end rounding still passes through the existing arc endpoint coverage.
+- Snap Angle enabled disables the free numeric Rotate textbox and enables the Rotate dropdown plus Step selector.
+- Snap Angle disabled re-enables the numeric Rotate textbox and disables the constrained dropdown controls.
+- Default 15 degree dropdown values and 45 degree Step-generated dropdown values were verified.
