📝 Walkthrough
Merge Risk: 🔵 Low · up to The popup renderer has no demonstrated production failure, but its test can pass without verifying a drawable label box. The change is mergeable with this bounded test improvement. Pre-merge checks |

1131-1131: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winPass resolved label settings to the hover test.
Sigma 2.4.0 resolves omitted label settings at runtime, but the test constructor stub does not. The test therefore passes incomplete settings to
drawDarkHover, which can produceNaNlabel-box coordinates without failing.Use representative resolved settings and record finite path coordinates.

Review comment at @tests/unit/report-view.test.js at line 1131: Update the hover-renderer test to pass representative resolved label settings, including labelSize, labelFont, and labelWeight, rather than the incomplete settings object. Record coordinates passed to the canvas path methods and assert they are all finite, ensuring the test catches invalid label-box geometry.
