It prepares deterministic work before launch and intercepts only runtime seams whose source, class-loader, and bytecode contracts are known.","accomplishments":["Recorded a 15.88s fresh-warm launch on the reviewed 83-mod profile; a fresh same-cohort release benchmark remains the public-delta gate.","Kept 42/42 transformed-class cache hits and 15,469 prepared texture and pixel-conversion hits active on that run.","Built fail-open runtime adapters, launch instrumentation, persistent prepared artifacts, desktop packaging, and rollback-aware update work around a game and mod ecosystem we do not control."],"reversal":"A valid prepared-pixel cache barely moved launch time until measurement found it sitting behind a roughly 27-second prefetch wait.
