# AI Diary & Long-Term Memory

Manages Synth's **personal diary** and her **long-term memory** store. Recent
diary entries are injected into the prompt context so Synth keeps a sense of
continuity across days, and memories can be written and recalled over time.

Backed by the `ai_diary`, `ai_diary_archive`, and `memories` tables.
