Implements a temporal memory system with Ebbinghaus-style forgetting curves for Claude. Memories decay exponentially unless reinforced through repeated access, with a scoring function that combines use count, time delta, and strength multipliers. Two storage layers: JSONL or SQLite for short-term working memory, and Markdown files with YAML frontmatter for promoted long-term storage. Memories below a forget threshold (default 0.05) get pruned, while those above a promote threshold (0.65) or accessed 5+ times in 14 days move to permanent storage. Tune half-life (default 3 days) and beta parameters to control how aggressively things fade. Good for contexts where you want the assistant to naturally retain frequently-used facts while letting ephemeral details drop away.
