v1.6.6

What's changed

MongrelDB engine

• Upgrade embedded stack to mongreldb-core / query / client / kit 0.64.14
• Residual-closure CI/reliability train: disk reclaim, MinHash median gate, history-status ordering, slim full-core

• Keeps the 0.63.1 WAL Put row layout so existing databases remain openable
• No public API changes vs 0.64.13

Tests

• Frozen sample-demo-v0.64.5 fixture retained; open-compat regression still passes on 0.64.14
• Demo kit_schema.json still openable by Kit 0.64.14

Packaging

• App version 1.6.6

v1.6.5

What's changed

ANN / semantic search

• Rewrite install_dense_ann to prepare embeddings before schema mutation and backfill via row_id puts
• Stamp configured_model only after a successful non-empty backfill
• Validate source text column ≠ embedding column; reject zero backfill limits
• Semantic search and install follow the active ANN embedding column (not hard-coded embedding / 384-d)
• MCP semantic_search accepts optional provider_id for application-supplied vectors

SQL / data integrity

• Serialize i64 / u64 outside JavaScript safe integer range as strings so SQL results and ANN hits keep full precision

UI

• Clear agent chat on connect and disconnect
• Reopen recent Direct paths with stored username / password / passphrase
• Table browser reloads projection correctly when the table changes
• Dimension-aware product quantization validation on install

Docs

• New architecture, connections, installation, and operations guides
• Expanded ANN, MCP, agent, SQL, table, deck, and onboarding docs

Packaging

• App version 1.6.5
