Long-form document tracing the actual discovery process: the wrong turns,
the aha moments, and the reasoning behind each step. Covers:
- Why EA is involved in a Steam game at all (link2ea:// architecture)
- JunoConfigureRegistry failure and why DISABLEROLLBACK was a dead end
- msiextract bypass as the actual solution
- Why direct system.reg edits don't survive reboots (wineserver ownership)
- The launch wrapper approach for registry persistence
- RPC_S_SERVER_UNAVAILABLE and EALocalHostSvc
- Wolf-specific bwrap capabilities mismatch
- localconfig.vdf atomic rename problem and chmod 555 fix
Written for sharing — no identifying information, explains the "why"
for each fix so readers can adapt if EA changes their MSI structure.
