revenge-plugins/shared/lib/rawFind.ts

// Revenge's own metro finders (findByProps/findByName/findByTypeName/findByStoreName, and even
// the bare `find`) cache their result per search - including a NEGATIVE result. Once a search
// comes up empty, it's marked "not found" and every later call with the same search never
// rescans window.modules again, even after the real module registers (confirmed by reading
// Revenge's own source: metro/internals/modules.ts's getModules() returns early on a cached
// NOT_FOUND flag). That makes retry loops pointless for any search whose first attempt happens
// to run before the target is registered - every retry after that first miss hits the same
// poisoned cache instead of actually looking again.
//
// This walks window.modules directly to bypass that cache - but critically, it never forces a
// module to initialize (never calls window.__r on something that hasn't run yet). An earlier
// version of this file did force-require everything on every scan, which is genuinely dangerous:
// Metro only ever runs a module's factory once and caches whatever it produced forever, so
// force-evaluating a module before whatever it depends on on is actually ready can permanently
// wedge it into a broken state for the rest of the session - no amount of retrying fixes that,
// since the factory never runs again. This only inspects modules Metro's own isInitialized flag
// says have ALREADY been required by something else, which is entirely passive and safe to poll
// repeatedly - it just waits for Discord's own code to naturally reach the module we want.
