0.13.0 — 2026-08-19

Release Notes

Added

• acknowledgments: temporal validity model (valid_until / last_verified, query-time expiry exclusion) credited to the Data Olympus lifecycle schema by @ajdelaguila (see README, discussion in #37)
• agent memory (#37): memory_store / memory_recall MCP tools + REST POST /memory/store, GET /memory/recall — durable cross-session memory in the memory vault with optional valid_until expiry, hybrid recall. Skill docs updated with memory + doc-graph endpoint reference
• doc-graph: temporal validity — get_doc_backlinks / get_related_docs (and the REST endpoints) now surface valid_until / last_verified on each link and exclude links whose either endpoint has expired, at query time (llm-kernel graph temporal-validity fields, #37). Querying an expired doc itself returns empty in both directions
• doc-graph: verify_doc MCP tool + POST /docs/verify — stamp last_verified=now on a doc node (llm-kernel mark_verified)
• doc-graph: count_expired_docs MCP tool + GET /docs/expired — count docs excluded from recall by expiry (llm-kernel count_expired_nodes)

Fixed

• doc-graph: expiry comparison now parses valid_until / now as RFC 3339 datetimes — a lexicographic string compare mis-ordered mixed UTC offsets (e.g. 23:00+09:00 vs 15:00Z), keeping expired docs in recall
• doc-graph: out-edge refresh (delete + re-insert on re-index) is now a single transaction via SqliteGraph::with_tx (llm-kernel 0.26.2) — a mid-refresh failure no longer leaves the doc with missing edges
• memory: memory_store rejects content over 1 MiB and validates valid_until as RFC 3339
• doc-graph: resolved -D warnings clippy failures on the lib target (dead-code on DocGraph/DocLink, collapsible ifs in extract_edges) that broke the CI Check job

Changed

• llm-kernel dependency moved from git rev dbf9c5f back to crates.io 0.26 (temporal validity published). Lifecycle calls (mark_verified, count_expired_nodes) now go through SqliteGraph wrapper methods instead of a direct rusqlite connection — doc-graph no longer enables the rusqlite feature
• doc-graph: link resolution no longer re-reads the queried node once per edge (one node read per link instead of two)
• doc-graph: incremental graph updates — incremental index runs now reprocess only changed files instead of re-reading every document (full rebuild only when the file set changes, tracked via .alcove/docgraph.stamp; also triggers on a missing docgraph.db). Graph build status is now surfaced in the index result JSON as doc_graph instead of being logged to stderr only
• Upgraded llm-kernel 0.15 → 0.25 (forward-compatible — no source changes; alcove's API surface was unaffected by the 0.16–0.25 breaking changes)

Re-index required for BGE-en-v1.5 and mxbai users. llm-kernel 0.25 extended the BGE-style instruction prefix ("Represent this sentence for searching relevant passages: ") from the Arctic models to BGESmallENV15, BGEBaseENV15, BGELargeENV15, and MxbaiEmbedLargeV1, which previously had no query prefix. alcove applies prefixes at both index and query time, so indexes built with an earlier llm-kernel using one of those four models now embed queries into a different region of the embedding space than their stored documents, degrading vector search relevance. Run alcove rebuild (or alcove vault rebuild <name> for a vault) to re-embed. The default model (MultilingualE5Small) and all other models are unaffected.
