 ## Evidence
 
 - The first `412 × 915` runtime capture confirms that the red-header height, divider width, both button frames and registration-entry height are close to the reference.
 - The same capture shows the seal too high, title clouds too wide, both button content groups too far right, and an agreement row that is too wide and high.
-- The second calibration adds sub-element anchors for those differences; the whole-image layer, registration side lines and four-corner button brackets remain forbidden.
+- The second calibration replaces the incorrect shared cloud artwork with three dedicated transparent assets: button corner flourish, divider center knot and title-side cloud. It also aligns the agreement checkbox and copy on one non-wrapping center line.
 
 ## Remaining runtime evidence
 
-- [P1] Capture the unchecked A-01 page at `412 × 915` in HBuilderX or Android, without browser chrome, after the second calibration and compare it against the source at the same scale.

 - [P1] Capture `320 × 568` after scrolling to confirm the agreement row and safe area are not clipped.
 - Confirm that selecting the agreement enables only the existing A-02 login route; the other entries remain local prepared-state prompts.
