v0.9.0

0.9.0 (2026-07-05)

Features

• log: size-triggered log.md rotation into _archive/logs/ (a20caa0)
• vecstore: numpy is the default vector backend; sqlite-vec becomes explicit opt-in (OpenSpec: make-sqlite-vec-opt-in) (#128) (ee5e744)

Bug Fixes

• ci: regenerate stale capabilities doc; generator writes LF (ade69c6)
• freshness: canonicalize event-path registry keys — Windows 8.3 aliases dropped live notes from event-maintained indexes (#129) (5f29525)
• indexes: excluded scan dirs stay excluded on the incremental paths (dca70d5)
• PyPI SETUP-LOCAL link + hooks recognise the renamed exomem tools (#118) (00c00d2)
• scripts: install-service no-UAC grant failed silently while claiming success (b672efa)
• writers: reuse the shared freshness-checked WikilinkResolver instead of rebuilding per write (8459def)

Performance

• claims: key the claim cache on the shared write-generation token (#127) (a04bcf7)
• embeddings: key the matrix caches on a write generation, not the WAL-checkpoint mtime (#125) (07e23cf)
• embeddings: numpy-lite — the matrix cache holds no chunk text (557dcf9)
• freshness: reconcile dispatches the drift delta through the event fan-out (#124) (ecca095)
• lexstore: heal from the freshness registry, not a filesystem walk (#122) (5b887e5)
• lexstore: incremental heal — patch only drifted rows, not a full O(corpus) rebuild (#121) (5415c3d)
• lexstore: route the _walk_matches_rows verify path through the registry too (#123) (d579df0)
• note: overlap the two corpus-aware passes; add suggestions= knob (default ON) (eef4523)
• yaml: parse frontmatter via libyaml CSafeLoader (measured 6.9x) (e3909ab)
