- File-based memory under .boocode/memory/ (project/user/reference topics) - Hierarchical 4-scope scan: global → home → project → session - Keyword/tag relevance matching for query-based recall - Injected as <boocode-memory> block in system prompt at assembly - v1 recall-only (extract/dream deferred to v2)
