Proper Framing - AGENTS.md is fixed and always contextual irrespective of its relevance; memory is the exact opposite of it. PMB does not dump the store in, rather extracts only a small top-k relevant chunk per task (a few hundred tokens generally), hence, more storage in the form of facts does not necessarily translate to more context. "Useless facts" are precisely what it is grading against, i.e., items which do not serve any purpose will simply be considered dead and decayed.
