Memory

Persist and retrieve agent memory across sessions — recall via the three-stage protocol (structure route → semantic search → navigation fallback), read via memory_load, see the wiki structure via memory_browse, write well-placed pages via memory_write (including section-level append/rewrite), maintain via memory_curate. Use whenever the user asks to remember/forget something, when you need to look up past decisions or context, or when episodic state matters beyond the current turn. Primary surface is the NATIVE memory_* tools (a `prismer memory` CLI appendix exists for code agents running in a shell).
