description	Pin or unpin a memini memory while preserving its existing tags. Use when the user wants a memory in every briefing.

pin (memini)

Locate the memory with memory_get or memory_recall and copy its id and namespace verbatim. Read its current tags: memory_update replaces rather than merges the tag list.

To pin, call memory_update with the existing tags plus pinned, preserving order and avoiding duplicates. To unpin, pass the existing tags minus pinned. If several candidates match, ask the user which one. Report the updated memory.

Pins are exempt from retro-tiering demotion, but not confidence decay or the briefing token/item budget. Warn when the pinned set is becoming large.
