Multi-page WCAG, Part 1: the machine behind 5,816 to 7

5,816 findings across 35 pages. Four CSS commits. Seven false positives left. This is the machine behind it - the discovery layer, and why its default chain runs three strategies, not four.

Performance audit, Part 2: A deterministic floor you can trust

The hard part of a performance tool is not the AI - it is numbers you can trust without a human pasting them in. How I proved the measured floor holds before letting any AI speak.

Performance audit, Part 1: My own tool gave my portfolio a C

My own performance tool gave my portfolio a C while every Core Web Vital stayed green - LCP 991 ms, CLS zero, five areas graded A. Why one score lies and two axes tell the truth.

Context-First QA, Part 1: The Thesis
