- Remove stale TODO(P0c) comment from main.go (resolved by P0c tier routing) - Wire config.Provider.Temperature → engine.Config.Temperature → provider.Request - Add WithMaxFileSize option to fs.write; wire cfg.Tools.MaxFileSize in main.go - Wire router.ReportOutcome after each runLoop return (success = err == nil) - Fix nil-callback guard on EventRouting dispatch (pre-existing bug exposed by new test)
