Hybrid search (BM25 + vector with RRF). Supports source filter, 1-hop graph expansion, quality gating.

Multi-hop retrieval with graph traversal + LLM gap-filling sub-queries. Best for bridging topics and multi-session synthesis.

Browse thoughts with salience-ordered filters (type, theme, topic, person, activity, days, min_quality).

Aggregate counts with type/theme breakdown, top topics, people, and activity.

Store a thought with auto-embedding, auto-linking, entity extraction, and semantic dedup merge.

Permanently delete a thought (cascades connections).

Rewrite a thought's content (re-embeds, re-extracts metadata).

LLM synthesis of recent themes, open loops, and suggested next steps.

Import runbook for external platforms (Notion, Obsidian, Readwise, etc.).

Graph traversal from a thought via typed links (extends, contradicts, is-evidence-for, etc.).

Graph analysis: hubs, density, sources, co_occurrence, themes, synthesis_candidates.

Duplicate candidate pairs with similarity zone histogram.

Recompute salience scores (recency × access × links × merges × source).

Browse extracted entities (person, project, tool, organization) by frequency.

Resurface forgotten high-quality thoughts across rediscovery/orphan/underrepresented/echo slots.

Pipeline monitoring: health, runs, merges.

Review flagged stale thoughts (list/approve/reject).
