Research best practices for datetime storage in SQLite and temporal querying patterns for LLM agents. Two approaches to evaluate: (1) Add a dedicated datetime column (e.g. created_at / captured_at) to the nodes table — requires an ALTER TABLE migration which is sensitive because the Mac app ships with a fixed schema. (2) Store temporal metadata in an existing metadata/JSON column to avoid schema changes. Research should cover: ISO 8601 vs Unix timestamps, timezone handling, how agents should query by time range, how to surface recency in MCP tool responses (e.g. rah_search_nodes returning temporal context), and how the start-here guide should instruct agents on temporal queries. Must coordinate with the packaged Mac app to ensure schema compatibility. Do this task directly after B7 (rename content→notes) since both touch the nodes table.",
