|
|
*
|
|
* Empirical Challenger Verification Suite for ControlBar (Issue #146 / Milestone 1 Batch 2).
|
|
*
|
|
* Requirements Tested:
|
|
* 1. Offscreen Canvas Rendering & Pixel Audit:
|
|
* - Decode authentic `public/ui/ctrlpnl-800.png` background panel.
|
|
* - Simulate Canvas 2D rendering of ControlBarHud across all xpRatio states (0%..100%, adversarial values).
|
|
* - Inspect pixel data inside the groove area `[256, 560, 120, 4]`:
|
|
* - Background pixels: `#070605` (7, 6, 5)
|
|
* - Filled progress pixels: `#d8d0a8` (216, 208, 168)
|
|
* - 9 tick notches at x = 256 + 12*i (i=1..9): `#1e1812` (30, 24, 18) across all 4 rows (y=560..563)
|
|
* - Surrounding Border Bleed Audit:
|
|
* - Top border row (y = 559, x in [256..375]): 100% match with base panel (ZERO bleed into gold trim)
|
|
* - Bottom border row (y = 564, x in [256..375]): 100% match with base panel (ZERO bleed into gold trim)
|
|
* - Left border (x = 255, y in [560..563]): 100% match with base panel (ZERO bleed)
|
|
* - Right border (x = 376, y in [560..563]): 100% match with base panel (ZERO bleed)
|
|
* - Corner pixels: (255, 559), (376, 559), (255, 564), (376, 564): 100% match with base panel
|
|
* 2. Hover Hit-Testing across DPRs and Aspect Ratios:
|
|
* - DPRs: 1.0, 1.25, 1.5, 2.0
|
|
* - Resolutions: 800x600 (4:3), 1920x1080 (16:9), 1280x720 (16:9), 2560x1440 (16:9), 1280x800 (16:10), 2560x1080 (21:9)
|
|
* - Logical boundary testing on all 4 corners and center of `EXP_BAR_HOVER_BOUNDS` (x in [256, 376], y in [558, 566])
|
|
* - Client integer pixel projection (physical browser mouse coordinates):
|
|
* - 100% of client pixels in [ceil(clientLeft), floor(clientRight)] trigger 'exp'
|
|
* - All client pixels outside trigger non-exp
|
|
* - Round-trip coordinate invariance: clientToLogical(logicalToClient(x, y)) === (x, y)
|
|
* - IEEE 754 precision boundary analysis at sub-pixel scale (3e-14)
|
|
* - 10,000-iteration random differential fuzzing harness under each display mode.
