Special Thanks
This release consolidates two fixes from @nxxxsooo, a first-time contributor to this project.
PATCH release: multi-store migration dimension safety and embedding-backend verification in memory status.
Fixed
- storage: multi-store vec0 migration now derives the target embedding dimension from the existing table DDL instead of the hardcoded 384 default, and adds a crash-safe durable backup with automatic recovery. Previously, migrating any non-384-dimension database recreated the table at 384 and permanently destroyed the embeddings (#134, PR #137).
- cli: memory status now verifies the embedding backend instead of reporting healthy after only reading storage stats. It surfaces the backend class, configured model, model dimension, and the database declared vec0 dimension; flags a degraded hash-fallback (semantic search non-functional) and model-versus-database dimension mismatches (writes will fail); and exits non-zero when a problem is found. Adds a --deep flag for a real store, search, delete round trip (#136, PR #139).
Note: PR #139 was merged manually (commit 431f20a) rather than through the standard merge button, because #137 landed first and both PRs added an entry to the same CHANGELOG.md Unreleased section, which could not be auto-merged. Both entries were kept; no code was altered from the PR branch head.
