measure: truthful scorecard (platform-aware cohort + real control baseline)#43
Merged
Conversation
…seline Two harness bugs made the real-binary scorecard undercount: 1. userAgent/platform cohort matchers hardcoded the MAC cohort, so a Linux (or Windows) build was flagged for reporting its own OS. Accept the per-OS RFP cohort (Mac/Windows/Linux) — a Linux RFP build reporting Linux is the Linux cohort, not a leak. 2. The --bin build bakes RFP into its autoconfig defaults, so an empty-pref 'control' ran hardened (control==hardened) and every 'mask' vector scored as not-normalized. Force a TRUE unhardened control (RFP/FPP/letterboxing off, fonts cleared) so mask vectors are judged against a real baseline. Re-measuring the existing binary with this harness will reflect the binary truthfully. Separately flagged: hardwareConcurrency/maxTouchPoints/dpr were NOT RFP-normalized in the hardened run despite RFP on (textMetrics/deviceMemory/ canvas/fonts all RFP-active) — a real open question to investigate.
