Implements the VectorStore ABC using sqlite-vec virtual tables.
Two-table design (vec0 virtual + companion meta) supports upsert,
top-k ANN query with optional metadata post-filter, delete by ID,
and bulk delete_where. Also renames VectorMatch.id → entry_id to
avoid shadowing the Python builtin, updating base.py and all tests.
Installed: sqlite-vec 0.1.9
Tests: 16 passed (7 base + 9 integration)
VectorMatch.entry_id renamed to VectorMatch.id to match the API contract
expected by downstream consumers (pagepiper T7). The dataclass remains frozen
to prevent field reassignment; metadata is kept as plain dict for JSON
deserialization compatibility.
- Renamed VectorMatch.entry_id field to id
- Updated all test references to use .id accessor
- Simplified metadata to plain dict (removed MappingProxyType wrapping)
- All 7 tests passing
