-          You are running inside the lancedb repository on a GitHub Actions runner. Your task is to fix a CI failure.
-
-          Input parameters:
-          - Failing workflow run URL: ${WORKFLOW_RUN_URL}
-          - Branch to fix: ${BRANCH}
-          - Additional guidelines: ${GUIDELINES:-"None provided"}
-
-          Follow these steps exactly:
-
-          1. Extract the run ID from the workflow URL. The URL format is https://github.com/lancedb/lancedb/actions/runs/<run_id>.
-
-          2. Use "gh run view <run_id> --json jobs,conclusion,name" to get information about the failed run.
-
-          3. Identify which jobs failed. For each failed job, use "gh run view <run_id> --job <job_id> --log-failed" to get the failure logs.
-
-          4. Analyze the failure logs to understand what went wrong. Common failures include:
-             - Compilation errors
-             - Test failures
-             - Clippy warnings treated as errors
-             - Formatting issues
-             - Dependency issues
-
-          5. Based on the analysis, fix the issues in the codebase:
-             - For compilation errors: Fix the code that doesn't compile
-             - For test failures: Fix the failing tests or the code they test
-             - For clippy warnings: Apply the suggested fixes
-             - For formatting issues: Run "cargo fmt --all"
-             - For other issues: Apply appropriate fixes
-
-          6. After making fixes, verify them locally:
-             - Run "cargo fmt --all" to ensure formatting is correct
-             - Run "cargo clippy --workspace --tests --all-features -- -D warnings" to check for issues
-             - Run ONLY the specific failing tests to confirm they pass now:
-               - For Rust test failures: Run the specific test with "cargo test -p <crate> <test_name>"
-               - For Python test failures: Build with "cd python && maturin develop" then run "pytest <specific_test_file>::<test_name>"
-               - For Java test failures: Run "cd java && mvn test -Dtest=<TestClass>#<testMethod>"
-               - For TypeScript test failures: Run "cd nodejs && pnpm build && pnpm test -- --testNamePattern='<test_name>'"
-               - Do NOT run the full test suite - only run the tests that were failing
-
-          7. If the additional guidelines are provided, follow them as well.
-
-          8. Inspect "git status --short" and "git diff" to review your changes.
-
-          9. Create a fix branch: "git checkout -b codex/fix-ci-<run_id>".
-
-          10. Stage all changes with "git add -A" and commit with message "fix: resolve CI failures from run <run_id>".
-
-          11. Push the branch: "git push origin codex/fix-ci-<run_id>". If the remote branch exists, delete it first with "gh api -X DELETE repos/lancedb/lancedb/git/refs/heads/codex/fix-ci-<run_id>" then push. Do NOT use "git push --force" or "git push -f".
-
-          12. Create a pull request targeting "${BRANCH}":
-              - Title: "ci: <short summary describing the fix>" (e.g., "ci: fix clippy warnings in lancedb" or "ci: resolve test flakiness in vector search")
-              - First, write the PR body to /tmp/pr-body.md using a heredoc (cat <<'PREOF' > /tmp/pr-body.md). The body should include:
-                - Link to the failing workflow run
-                - Summary of what failed
-                - Description of the fixes applied
-              - Then run "gh pr create --base ${BRANCH} --body-file /tmp/pr-body.md".
-
-          13. Display the new PR URL, "git status --short", and a summary of what was fixed.
-
-          Constraints:
-          - Use bash commands for all operations.
-          - Do not merge the PR.
-          - Do not modify GitHub workflow files unless they are the cause of the failure.
-          - If any command fails, diagnose and attempt to fix the issue instead of aborting immediately.
-          - If you cannot fix the issue automatically, create the PR anyway with a clear explanation of what you tried and what remains to be fixed.
-          - env "GH_TOKEN" is available, use "gh" tools for GitHub-related operations.

-          5. Ensure the repository is clean except for intentional changes. Inspect "git status --short" and "git diff" to confirm the dependency update and any required fixes.

+* Format: `cargo fmt --all`
 
-For Python validation, prefer the uv-managed environment declared by `python/uv.lock`.
-Do not treat system `python`, global `pytest`, or missing editable-install errors as
-final blockers; bootstrap or enter the uv environment instead. If `lancedb._lancedb`
-is missing or stale, or if Rust/PyO3 binding code changed, rebuild the Python
-extension with the bootstrap command above before running tests.
-
-Before committing changes, run formatting for every language you touched. At minimum:
-
-* Rust changes: run `cargo fmt --all`.
-* Python changes: run `ruff format .` and `ruff check .` from the repository root,
-  and run targeted tests through `cd python && uv run ...`.
-* TypeScript changes: run the relevant `npm`/`pnpm` lint, format, build, and docs commands in `nodejs`.
-
-Before creating a PR, make sure the PR title follows Conventional Commits, such as
-`fix: support nested field paths in native index creation` or
-`feat(python): add dataset multiprocessing support`. The semantic-release check uses the
-PR title and body as the merge commit message, so a non-conventional PR title will fail CI.
+Before committing changes, run formatting.

-# VoyageAI Embeddings : Multimodal
-
-VoyageAI embeddings can also be used to embed both text and image data, only some of the models support image data and you can check the list
-under [https://docs.voyageai.com/docs/multimodal-embeddings](https://docs.voyageai.com/docs/multimodal-embeddings)
-
-Supported multimodal models:
-
-- `voyage-multimodal-3` - 1024 dimensions (text + images)
-- `voyage-multimodal-3.5` - Flexible dimensions (256, 512, 1024 default, 2048). Supports text, images, and video.
-
-### Video Support (voyage-multimodal-3.5)
-
-The `voyage-multimodal-3.5` model supports video input through:
-- Video URLs (`.mp4`, `.webm`, `.mov`, `.avi`, `.mkv`, `.m4v`, `.gif`)
-- Video file paths
-
-Constraints: Max 20MB video size.
-
-Supported parameters (to be passed in `create` method) are:
-
-| Parameter | Type | Default Value           | Description                               |
-|---|---|-------------------------|-------------------------------------------|
-| `name` | `str` | `"voyage-multimodal-3"` | The model ID of the VoyageAI model to use |
-| `output_dimension` | `int` | `None` | Output dimension for voyage-multimodal-3.5. Valid: 256, 512, 1024, 2048 |
-
-Usage Example:
-
-```python
-import base64
-import os
-from io import BytesIO
-
-import requests
-import lancedb
-from lancedb.pydantic import LanceModel, Vector
-from lancedb.embeddings import get_registry

-    buffered = BytesIO(image_bytes)
-    img_str = base64.b64encode(buffered.getvalue())
-    return img_str.decode("utf-8")

-    vector: Vector(func.ndims()) = func.VectorField()  # vector column
-    vec_from_bytes: Vector(func.ndims()) = func.VectorField()  # Another vector column
-
-
-if "images" in db.table_names():

-```
-Now we can search using text from both the default vector column and the custom vector column
-```python
-
-# text search
-actual = table.search("man's best friend", "vec_from_bytes").limit(1).to_pydantic(Images)[0]
-print(actual.label) # prints "dog"
-
-frombytes = (
-    table.search("man's best friend", vector_column_name="vec_from_bytes")
-    .limit(1)
-    .to_pydantic(Images)[0]
-)
-print(frombytes.label)
-
-```
-
-Because we're using a multi-modal embedding function, we can also search using images
-
-```python
-# image search
-query_image_uri = "http://farm1.staticflickr.com/200/467715466_ed4a31801f_z.jpg"
-image_bytes = requests.get(query_image_uri).content

-# VoyageAI Embeddings
-
-Voyage AI provides cutting-edge embedding and rerankers.
-
-
-Using voyageai API requires voyageai package, which can be installed using `pip install voyageai`. Voyage AI embeddings are used to generate embeddings for text data. The embeddings can be used for various tasks like semantic search, clustering, and classification.
-You also need to set the `VOYAGE_API_KEY` environment variable to use the VoyageAI API.
-
-Supported models are:
-
-**Voyage-4 Series (Latest)**
-
-- voyage-4 (1024 dims, general-purpose and multilingual retrieval, 320K batch tokens)
-- voyage-4-lite (1024 dims, optimized for latency and cost, 1M batch tokens)
-- voyage-4-large (1024 dims, best retrieval quality, 120K batch tokens)
-
-**Voyage-3 Series**
-
-- voyage-3
-- voyage-3-lite
-
-**Domain-Specific Models**
-
-- voyage-finance-2
-- voyage-multilingual-2
-- voyage-law-2
-- voyage-code-2
-
-
-Supported parameters (to be passed in `create` method) are:
-
-| Parameter | Type | Default Value | Description |
-|---|---|--------|---------|
-| `name` | `str` | `None` | The model ID of the model to use. Supported base models for Text Embeddings: voyage-4, voyage-4-lite, voyage-4-large, voyage-3, voyage-3-lite, voyage-finance-2, voyage-multilingual-2, voyage-law-2, voyage-code-2 |
-| `input_type` | `str` | `None` | Type of the input text. Default to None. Other options: query, document. |
-| `truncation` | `bool` | `True` | Whether to truncate the input texts to fit within the context length. |
-
-
-Usage Example:
-    
-```python
-    import lancedb
-    from lancedb.pydantic import LanceModel, Vector
-    from lancedb.embeddings import EmbeddingFunctionRegistry
-
-    voyageai = EmbeddingFunctionRegistry

-# Java SDK
-
-The LanceDB Java SDK provides a convenient way to interact with LanceDB Cloud and Enterprise deployments using the Lance REST Namespace API.
-
-!!! note
-    The Java SDK currently only works for LanceDB remote database that connects to LanceDB Cloud and Enterprise.
-    Local database support is a work in progress. Check [LANCEDB-2848](https://github.com/lancedb/lancedb/issues/2848) for the latest progress.
-
-## Installation
-
-Add the following dependency to your `pom.xml`:
-
-```xml
-<dependency>
-    <groupId>com.lancedb</groupId>
-    <artifactId>lancedb-core</artifactId>
-    <version>0.29.1-beta.0</version>
-</dependency>
-```
-
-## Quick Start
-
-### Connecting to LanceDB Cloud
-
-```java
-import com.lancedb.LanceDbNamespaceClientBuilder;
-import org.lance.namespace.LanceNamespace;
-
-// If your DB url is db://example-db, then your database here is example-db
-LanceNamespace namespaceClient = LanceDbNamespaceClientBuilder.newBuilder()
-    .apiKey("your_lancedb_cloud_api_key")
-    .database("your_database_name")
-    .build();
-```
-
-### Connecting to LanceDB Enterprise
-
-For LanceDB Enterprise deployments with a custom endpoint:
-
-```java
-LanceNamespace namespaceClient = LanceDbNamespaceClientBuilder.newBuilder()
-    .apiKey("your_lancedb_enterprise_api_key")
-    .database("your_database_name")
-    .endpoint("<your_enterprise_endpoint>")
-    .build();
-```
-
-### Configuration Options
-
-| Method | Description | Required |
-|--------|-------------|----------|
-| `apiKey(String)` | LanceDB API key | Yes |
-| `database(String)` | Database name | Yes |
-| `endpoint(String)` | Custom endpoint URL for Enterprise deployments | No |
-| `region(String)` | AWS region (default: "us-east-1") | No |
-| `config(String, String)` | Additional configuration parameters | No |
-
-## Metadata Operations
-
-### Creating a Namespace Path
-
-Namespace paths organize tables hierarchically. Create the desired namespace path before creating tables within it:
-
-```java
-import org.lance.namespace.model.CreateNamespaceRequest;
-import org.lance.namespace.model.CreateNamespaceResponse;
-
-// Create a child namespace path
-CreateNamespaceRequest request = new CreateNamespaceRequest();
-request.setId(Arrays.asList("my_namespace"));
-
-CreateNamespaceResponse response = namespaceClient.createNamespace(request);
-```
-
-You can also create nested namespace paths:
-
-```java
-// Create a nested namespace path: parent/child
-CreateNamespaceRequest request = new CreateNamespaceRequest();
-request.setId(Arrays.asList("parent_namespace", "child_namespace"));
-
-CreateNamespaceResponse response = namespaceClient.createNamespace(request);
-```
-
-### Describing a Namespace Path

-
-## Writing Data
-
-### Creating a Table
-
-Tables are created within a namespace path by providing data in Apache Arrow IPC format:
-
-```java
-import org.lance.namespace.LanceNamespace;
-import org.lance.namespace.model.CreateTableRequest;
-import org.lance.namespace.model.CreateTableResponse;
-import org.apache.arrow.memory.BufferAllocator;
-import org.apache.arrow.memory.RootAllocator;

-import org.apache.arrow.vector.types.pojo.ArrowType;
-import org.apache.arrow.vector.types.pojo.Field;
-import org.apache.arrow.vector.types.pojo.FieldType;
-import org.apache.arrow.vector.types.pojo.Schema;
-
-import java.io.ByteArrayOutputStream;
-import java.nio.channels.Channels;
-import java.util.Arrays;
-
-// Create schema with id, name, and embedding fields
-Schema schema = new Schema(Arrays.asList(
-    new Field("id", FieldType.nullable(new ArrowType.Int(32, true)), null),
-    new Field("name", FieldType.nullable(new ArrowType.Utf8()), null),
-    new Field("embedding",
-        FieldType.nullable(new ArrowType.FixedSizeList(128)),
-        Arrays.asList(new Field("item",
-            FieldType.nullable(new ArrowType.FloatingPoint(FloatingPointPrecision.SINGLE)),
-            null)))
-));
-
-try (BufferAllocator allocator = new RootAllocator();
-     VectorSchemaRoot root = VectorSchemaRoot.create(schema, allocator)) {
-
-    // Populate data
-    root.setRowCount(3);
-    IntVector idVector = (IntVector) root.getVector("id");
-    VarCharVector nameVector = (VarCharVector) root.getVector("name");

-
-    for (int i = 0; i < 3; i++) {
-        idVector.setSafe(i, i + 1);
-        nameVector.setSafe(i, ("item_" + i).getBytes());
-        embeddingVector.setNotNull(i);
-        for (int j = 0; j < 128; j++) {
-            embeddingData.setSafe(i * 128 + j, (float) i);
-        }
-    }
-    idVector.setValueCount(3);
-    nameVector.setValueCount(3);
-    embeddingData.setValueCount(3 * 128);
-    embeddingVector.setValueCount(3);
-
-    // Serialize to Arrow IPC format
-    ByteArrayOutputStream out = new ByteArrayOutputStream();
-    try (ArrowStreamWriter writer = new ArrowStreamWriter(root, null, Channels.newChannel(out))) {
-        writer.start();
-        writer.writeBatch();
-        writer.end();
-    }
-    byte[] tableData = out.toByteArray();
-
-    // Create a table in a namespace path
-    CreateTableRequest request = new CreateTableRequest();
-    request.setId(Arrays.asList("my_namespace", "my_table"));
-    CreateTableResponse response = namespaceClient.createTable(request, tableData);
-}
-```
-
-### Insert
-
-```java
-import org.lance.namespace.model.InsertIntoTableRequest;
-import org.lance.namespace.model.InsertIntoTableResponse;
-
-// Prepare data in Arrow IPC format (similar to create table example)
-byte[] insertData = prepareArrowData();

-request.setMode(InsertIntoTableRequest.ModeEnum.APPEND);
-
-InsertIntoTableResponse response = namespaceClient.insertIntoTable(request, insertData);
-System.out.println("New version: " + response.getVersion());
-```
-
-### Update
-
-Update rows matching a predicate condition:
-
-```java
-import org.lance.namespace.model.UpdateTableRequest;
-import org.lance.namespace.model.UpdateTableResponse;
-
-UpdateTableRequest request = new UpdateTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-// Predicate to select rows to update
-request.setPredicate("id = 1");
-
-// Set new values using SQL expressions as [column_name, expression] pairs
-request.setUpdates(Arrays.asList(
-    Arrays.asList("name", "'updated_name'")
-));
-
-UpdateTableResponse response = namespaceClient.updateTable(request);
-System.out.println("Updated rows: " + response.getUpdatedRows());
-```
-
-### Delete
-
-Delete rows matching a predicate condition:
-
-```java
-import org.lance.namespace.model.DeleteFromTableRequest;
-import org.lance.namespace.model.DeleteFromTableResponse;
-
-DeleteFromTableRequest request = new DeleteFromTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-// Predicate to select rows to delete
-request.setPredicate("id > 100");
-
-DeleteFromTableResponse response = namespaceClient.deleteFromTable(request);
-System.out.println("New version: " + response.getVersion());
-```
-
-### Merge Insert (Upsert)
-
-Merge insert allows you to update existing rows and insert new rows in a single operation based on a key column:
-
-```java
-import org.lance.namespace.model.MergeInsertIntoTableRequest;
-import org.lance.namespace.model.MergeInsertIntoTableResponse;
-
-// Prepare data with rows to update (id=2,3) and new rows (id=4)
-byte[] mergeData = prepareArrowData();  // Contains rows with id=2,3,4
-
-MergeInsertIntoTableRequest request = new MergeInsertIntoTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-// Match on the "id" column
-request.setOn("id");
-
-// Update all columns when a matching row is found
-request.setWhenMatchedUpdateAll(true);
-
-// Insert new rows when no match is found
-request.setWhenNotMatchedInsertAll(true);
-
-MergeInsertIntoTableResponse response = namespaceClient.mergeInsertIntoTable(request, mergeData);
-
-System.out.println("Updated rows: " + response.getNumUpdatedRows());
-System.out.println("Inserted rows: " + response.getNumInsertedRows());
-```
-
-## Querying Data
-
-### Counting Rows
-
-```java
-import org.lance.namespace.model.CountTableRowsRequest;
-
-CountTableRowsRequest request = new CountTableRowsRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-Long rowCount = namespaceClient.countTableRows(request);

-query.setK(10);
-query.setFilter("id > 50");
-query.setColumns(Arrays.asList("id", "name"));
-
-byte[] result = namespaceClient.queryTable(query);
-```
-
-### Query with Prefilter
-
-```java
-QueryTableRequest query = new QueryTableRequest();
-query.setId(Arrays.asList("my_namespace", "my_table"));
-query.setK(5);
-query.setPrefilter(true);  // Apply filter before vector search
-query.setFilter("category = 'electronics'");
-
-// Set query vector

-vector.setSingleVector(queryVector);
-query.setVector(vector);
-

-# Class: Scannable
-
-A data source that can be scanned as a stream of Arrow `RecordBatch`es.
-
-`Scannable` wraps the schema + optional row count + rescannable flag and
-a callback that yields batches one at a time. It is passed to consumers
-(e.g. `Table.add`, `createTable`, `mergeInsert` — follow-up work) that
-need to pull data without materializing the full dataset in JS memory.
-
-Batches cross the JS↔Rust boundary as Arrow IPC Stream messages; a fresh
-writer serializes each batch, and the Rust side decodes it with
-`arrow_ipc::reader::StreamReader`. One batch is in flight at a time.
-
-## Properties
-
-### numRows
-
-```ts
-readonly numRows: null | number;
-```
-
-***
-
-### rescannable
-
-```ts
-readonly rescannable: boolean;
-```

-***
-
-### schema
-
-```ts
-readonly schema: Schema<any>;
-```
-
-## Methods
-
-### fromFactory()
-
-```ts
-static fromFactory(
-   schema,
-   factory,
-   opts): Promise<Scannable>
-```
-
-Build a Scannable from an explicit schema and a factory that returns a
-fresh batch iterator on each call.
-
-The factory is invoked once per scan. Each iterator yields
-`RecordBatch`es matching the declared schema. Use this when you need
-direct control over the pull loop — for example, to wrap a streaming
-source whose batches are produced lazily.
-
-#### Parameters
-
-* **schema**: `Schema`&lt;`any`&gt;
-    The Arrow schema of the produced batches.
-
-* **factory**
-    Called at the start of each scan to produce a batch
-    iterator. Must be idempotent when `rescannable` is true.
-
-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`
-    Optional hints. `rescannable` defaults to `true`; set to
-    `false` if calling `factory()` twice would not reproduce the same data.
-
-#### Returns
-
-`Promise`&lt;[`Scannable`](Scannable.md)&gt;
-
-***
-
-### fromIterable()
-
-```ts
-static fromIterable(
-   schema,
-   iter,
-   opts): Promise<Scannable>
-```
-
-Build a Scannable from an iterable of `RecordBatch`es. `rescannable`
-defaults to `false`. Pass an explicit schema so the consumer can
-validate before any batch is pulled.
-
-`opts.rescannable: true` is honest for replayable iterables (Arrays,
-Sets, or custom iterables whose `[Symbol.iterator]()` returns a fresh
-iterator each call). It is rejected for one-shot iterables (generators,
-async generators, or already-an-iterator inputs) because their
-`[Symbol.iterator]()` returns the same exhausted object on the second
-scan. For replayable sources outside this shape, use
-`fromFactory(schema, () => createIter(), { rescannable: true })`.
-
-Note: when `opts.rescannable` is `true`, the constructor calls
-`[Symbol.iterator]()` once on the input to perform the structural check.
-
-#### Parameters
-
-* **schema**: `Schema`&lt;`any`&gt;
-
-* **iter**: `Iterable`&lt;`RecordBatch`&lt;`any`&gt;&gt; \| `AsyncIterable`&lt;`RecordBatch`&lt;`any`&gt;&gt;
-
-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`

-***
-
-### fromRecordBatchReader()
-
-```ts
-static fromRecordBatchReader(reader, opts): Promise<Scannable>
-```
-
-Build a Scannable from an Arrow `RecordBatchReader`. A reader can only
-be consumed once; `rescannable` defaults to `false`.
-
-The reader must already be opened (via `.open()`) so its `.schema` is
-populated. `RecordBatchReader.from(...)` returns an unopened reader.
-
-`opts.rescannable: true` is rejected because `RecordBatchReader` is a
-self-iterator (its `[Symbol.iterator]()` returns itself), and this
-constructor does not call `reader.reset()` between scans, so a second
-scan would always see an exhausted reader. For genuinely replayable
-sources, use
-`fromFactory(schema, () => openReader(), { rescannable: true })`,
-which mints a fresh reader on each scan.
-
-#### Parameters
-
-* **reader**: `RecordBatchReader`&lt;`any`&gt;
-
-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`
-
-#### Returns

-
-***
-
-### fromTable()
-
-```ts
-static fromTable(table, opts): Promise<Scannable>
-```
-
-Build a Scannable from an in-memory Arrow `Table`. Always rescannable;
-the table's batches are replayed on each scan.
-
-The table's row count is authoritative: `opts.numRows` must either be
-omitted or equal to `table.numRows`. `opts.rescannable` of `false` is
-rejected because in-memory Tables are always rescannable.
-
-#### Parameters
-
-* **table**: `Table`&lt;`any`&gt;
-
-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`
