+**The Cortex** sees across all channels, workers, and branches simultaneously. It maintains the agent's working memory — a layered context assembly system that gives every conversation structured awareness of what's happening across the agent. Events are recorded as they happen; intra-day synthesis compresses them into narrative; daily summaries roll up at midnight; knowledge synthesis regenerates when the memory graph changes. The cortex supervises processes and maintains the memory graph.

 ### Memory
 
-Spacebot's memory is a typed, graph-connected knowledge system in SQLite and LanceDB. Every memory has a type, an importance score, and graph edges to related memories. The agent distinguishes facts from decisions, preferences from goals. That structure lets the cortex synthesize a useful briefing rather than dumping raw search results into context.

 - **Eight memory types** — Fact, Preference, Decision, Identity, Event, Observation, Goal, Todo
 - **Graph edges** — RelatedTo, Updates, Contradicts, CausedBy, PartOf
 - **Hybrid recall** — vector similarity + full-text search merged via Reciprocal Rank Fusion
 - **Memory import** — drop files into `ingest/` and Spacebot extracts structured memories automatically. Supports text, markdown, and PDF.
