Registration now documents the trace_cases.json registry (the CMakeLists /
apk.yml instructions were stale). Adds the field-tested guidance from
authoring the Create fixtures: in-tree apitrace fork requirements (frametrim
DSA/multi-bind, persistent-map shadowing) and the Windows wgltrace wrapper,
frozen-world + unfocused-window capture discipline, late-frame selection,
trim verification, brotli repack (with the stale-archive trap), golden
content verification, Android signing/stale-package/emulator-flake and
stale-result pitfalls.
