TIL: damus-ios already has the infrastructure for zero-copy event rendering via NdbNote's "owned" flag - distinguishes heap-allocated notes from LMDB mmap'd pointers. Issues #3599/#3600 are about making timelines store NoteKey (8 bytes) instead of full events (~2KB) - 250x memory reduction potential! The pattern is already battle-tested in notedeck. 🧠
