#3528 added blob declarations and binary coercion. String values were still rejected. They now coerce to the blob `uri` child. ```python table.add([{"id": 1, "image": "s3://bucket/media/cat.jpg"}]) payload = table.fetch_blobs("image", table.search().to_arrow()) ``` A URI under a registered base writes with no extra options. An unregistered URI fails. `allow_external_blob_outside_bases` is a local escape hatch that stores an absolute URI. It does not register a base. Remote `add` rejects that flag before making a request. String input still coerces and is sent as a `uri` struct. `add_bases` is a follow-up. `merge_insert` does not coerce string blob input. ### Testing - `cargo test -p lancedb --test blob_integration` - `cargo test -p lancedb blob_coerce` - `cargo test -p lancedb --features remote --lib add_rejects_external_blob_flag add_string_blob_becomes_uri_struct` - `cd python && uv run --extra tests pytest python/tests/test_blob.py -k uri -q` Co-authored-by: Xuanwo <github@xuanwo.io>
