Generated by npm run join. Joins the static map in signals.json against what captures actually carried, one column per browser, so a row is what the collector reports on real hardware next to what its source says it can report.

A cell is the reported value: sN where the status was non-zero, {a,b} for an object's keys, [n] for an array's length, #abcd1234 for a digest, the value itself otherwise. ≠ marks a signal whose value differs between browsers, which is the set an anti-detect build has to keep coherent; everything else is constant across all of them.

notes is where static and observed disagree: a status code no branch produces, object keys the source never names, a digest from a collector with no hash call on its path. Each is a gap in the static read.
