Retrieval over the vault. v1.0 ships FTS5 BM25 with Turkish casefold normalization. Optional date and frontmatter type filters. Returns ranked hits with snippets. The cards array (EvidenceCard) is the preferred output and carries content_hash, trust, and confidence_label. Each card carries a backend field identifying which retrieval leg produced it (fts5, dense, kg). The backends_used array lists every backend that returned at least one hit. hits is kept for backward compatibility.

Retrieve documents by session_id or date range. Returns paths, titles, mtimes, and (when include_body) the markdown body of each match.

Atomically append or replace a markdown section in a vault file. Enforces assertWithinVault path containment. Optional frontmatter applies to newly created files only.

Topic summary grouped by directory. v1.0 uses FTS5 and can add Graphiti fields when full-profile KG state is active.

Temporal-ordered references for a subject. v1.0 returns FTS5 hits sorted by mtime ascending and can add bi-temporal Graphiti facts when full-profile KG state is active.

Preflight context bundle for a new session. Combines recent session-typed docs and topic-relevant matches inside a token budget. v1.0 uses the full injection format; Phase F.5 adds the keypoints/ref Adaptive Context Layer. Pass session_id (from CLAUDE_SESSION_ID) to activate per-session injection deduplication and progressive format selection (full → keypoints → ref as context fills).
