Why I Permanently NO-GO'd Patchright After a Spike (And the Anti-Detection Decision Tree)

TL;DR : My web-agent runs sannysoft.com anti-bot tests. vanilla playwright passes 19/32, with playwright-stealth it's 21/32, but patchright (claimed stronger) — still 19/32, identical to vanilla. The reason: patchright's patches all sit in the launch phase, but I take over already-launched Chrome via connect_over_cdp — entirely bypassed. 8 chapters + 3 mermaid figures (xychart bar comparison + 2 decision flowcharts).
