Document::try_get kept only objects that loaded. An object whose entry points at something that doesn't parse falls back to a whole-file search (scan_for); that failed too, nothing was kept, and the next read searched the whole file again. A caller that reads such an object repeatedly, such as the window title of a file whose document information dictionary is damaged and that asks for its title to be shown, paid one whole-file search per read, several per frame. The cache now keeps the load result, a failure as well. It is the same map with the same bounds, clears and per-reader privacy, so every place that drops loaded objects (authentication, reconstruction, private scan readers, eviction) drops remembered failures too. Edits are read from the overlay before the cache, as before, so a set or freed number still answers for itself. A failure is kept in nested loads too, as a success already is; only a poisoned lock is never kept. Failures count towards the cache's object caps and hold no bytes of their own. Sharing the map between clones stays sound because entries, data and the stream limit don't change after open. Test: an_unreadable_object_is_searched_for_once counts whole-file searches through a test-only counter (like SECTION_READS): one for eleven reads and a clone's read. With failures not kept it counts 22. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SqmHYx8FiWM5PcsoiErgp9
