Drew Gallardo 41ac32a344 feat(rust): add blob read and materialization APIs (#3562) 
This PR is for the Read path against blob v2. #3528 handles declare +
write, and this this adds materialization on local tables.

- blob_columns()
- fetch_blobs(column, row_ids) → bytes
- fetch_blob_files(column, row_ids) → lazy handles
- Pass _rowid from query().with_row_id(). Remote returns NotSupported.
(for now)

### Use cases

search, grab row ids, materialize images:

```rust
let row_ids = /* _rowid from hits */;
let images = table.fetch_blobs("image", &row_ids).await?;
```

Large blobs: open handles, read only what you need:

```rust
let handles = table.fetch_blob_files("image", &row_ids).await?;
let bytes = handles[0].as_ref().unwrap().read().await?;
```

Filter then batch fetch: collect ids from a filter, one call.
Multiple blob columns: image and thumbnail independently.
Row ids from before compact: still resolve.

### Alignment note
Lance `read_blobs` drops null rows. We descriptor-take first, read
non-null ids, re-expand to match input order. Null and zero-length blobs
come back null/None. Bytes path sets `preserve_order(true)`. So I added:

```
TODO(lance): expose selection_index or an aligned execute so we can drop the pre-read.
```

### Tests
`cargo test -p lancedb --test blob_integration`
- 30 tests covering nulls, reorder, dups, cross-fragment bytes + files,
compact, delete, legacy v1 errors.

Drew Gallardo ba1ef34481 feat(rust): add blob v2 schema declaration and write path (#3528) 
First Rust PR for #3231. Lance already stores blob v2. This adds the
LanceDB write side.

```rust
let schema = Schema::new(vec![
    Field::new("id", DataType::Int64, false),
    lancedb::blob("image", true),
]);

let table = db.create_table("photos", schema).execute().await?;

table.add(batch_with_large_binary_image_column).execute().await?;
```

Read/materialize and Python are follow-up PRs.

### Testing

- cargo test -p lancedb --test blob_integration
- cargo test -p lancedb blob:: datafusion::blob_coerce
- cargo test -p lancedb (591 passed)
- cargo clippy --features remote --tests

Will Jones 85d870b397 fix: parse RFC 3339 created_at and improve IndexConfig repr (#3558) 
The server now serializes an index's `created_at` as an RFC 3339 string
(e.g. `"2026-06-18T21:37:36.637Z"`), but the client deserializer only
accepted a unix timestamp in milliseconds. This caused `list_indices` to
fail with:

```
Failed to parse list_indices response: invalid type: string "2026-06-18T21:37:36.637Z", expected a unix timestamp in milliseconds
```

This PR replaces the fixed millisecond deserializer with a custom one
that accepts both an RFC 3339 string (current server) and a
unix-millisecond integer (legacy deployments), so the client works
against any server version.

It also improves the `IndexConfig` repr in the Python bindings.
Previously it printed only three fields (`Index(FTS, columns=["text"],
name="text_idx")`), hiding the metadata that `list_indices` returns. It
now renders every populated field, omitting any that are `None`. Each
value is valid Python — integer counts use `_` thousands separators and
`created_at` uses the `datetime` repr — so values round-trip. The real
repr is a single line; it's wrapped here for readability:

```python
>>> table.list_indices()
[IndexConfig(
    name="text_idx",
    index_type="FTS",
    columns=["text"],
    index_uuid="aefd3e00-2f95-4bdc-92ac-06de84442bf1",
    type_url="/lance.table.InvertedIndexDetails",
    created_at=datetime.datetime(2026, 6, 18, 21, 37, 36, 637000, tzinfo=datetime.timezone.utc),
    num_indexed_rows=2,
    size_bytes=3_669,
    num_segments=1,
    index_version=1,
    index_details={
        'lance_tokenizer': None,
        'base_tokenizer': 'simple',
        'language': 'English',
        'with_position': False,
        'max_token_length': 40,
        'lower_case': True,
        'stem': True,

        'max_ngram_length': 3,

    },
)]
```

Will Jones ce5dadd386 fix(ci): allow shell pre-commit hooks in bumpversion configs (#3554) 
The "Create release commit" workflow (`make-release-commit.yml`) has
failed on its last two runs; no release tags have been created since
June 4. Since this workflow creates the tag that the cargo/npm/pypi/java
publish workflows trigger off of, all recent releases are effectively
blocked.

The workflow installs `bump-my-version` unpinned. Version `1.4.0` added
a check that refuses to run `pre_commit_hooks` containing shell syntax
(pipes, `&&`, `if`, variable expansion) unless `allow_shell_hooks =
true` is set. Both bumpversion configs use such hooks:

- `python/.bumpversion.toml` — updates `Cargo.lock` after the bump
(fails first)
- `.bumpversion.toml` — runs `mvn versions:set` for the Java packages

The job dies at the version-bump step with:

> Hook '…' contains shell syntax (pipes, redirects, or variable
expansion). Set `allow_shell_hooks = true` in your configuration to
enable shell execution…

This sets `allow_shell_hooks = true` in both configs to restore the
previous behavior.

Armaan Sandhu 1f8ebef3cd fix(rust): return typed errors instead of panicking in Bedrock embedding path (#3512) 
Closes #3506

## Problem

The Bedrock embedding compute path
(`rust/lancedb/src/embeddings/bedrock.rs`) panics instead of returning a
typed error in several places:

- `serde_json::to_vec(&request_body).unwrap()`: request serialization.
- `block_in_place(...).unwrap()`: the AWS `invoke_model` send result;
any API error terminates the worker instead of propagating.
- `v.as_f64().unwrap() as f32`: panics on non-numeric values in the
returned embedding array.
- `Handle::current()` + `block_in_place` assume a multi-threaded Tokio
runtime and panic when that assumption does not hold (no runtime, or a
current-thread runtime).

Malformed payloads, non-numeric embedding values, or an incompatible
runtime should surface as typed errors and never panic.

## Fix

- Serialize the request body before the blocking section so a
serialization failure returns `Error::Runtime` via `?`.
- Map the `invoke_model` send error to `Error::Runtime` instead of
`unwrap`.
- Add a `json_array_to_f32` helper that converts the response array to
`Vec<f32>`, returning `Error::Runtime` for a missing/non-array field or
a non-numeric element (used by both the Titan and Cohere paths).
- Add `current_multi_thread_handle()` (`Handle::try_current()` + a
`RuntimeFlavor::CurrentThread` guard) so an absent or incompatible
runtime returns a typed error rather than panicking in `block_in_place`.

Scope note: the sibling `openai.rs` provider uses the same
`block_in_place` + `block_on` bridge, so the bridge pattern itself is
kept; this change only removes the panic paths that are specific to the
Bedrock provider.

## Testing

Added 6 unit tests (no AWS credentials required):

- `json_array_to_f32`: valid numbers, non-array payload, and non-numeric
element.
- `current_multi_thread_handle`: errors with no runtime, errors on a
current-thread runtime, and succeeds on a multi-threaded runtime.

All pass; `cargo fmt` and `cargo clippy` clean. Build/test with
`--features bedrock,lance/protoc`.

JSap0914 9128dbcd7a fix(util): escape single quotes in struct field names in value_to_sql (#3548) 
### Bug

`value_to_sql({...})` builds a DataFusion `named_struct(...)` literal
but interpolates the struct field names directly as `f"'{k}'"`. A field
name that contains a single quote therefore produces invalid SQL:

```python
>>> from lancedb.util import value_to_sql
>>> value_to_sql({"it's": 1})
"named_struct('it's', 1)"        # invalid SQL — the quote terminates the literal
```

String *values* are already escaped (single quotes doubled) by the `str`
branch of `value_to_sql`, so keys and values were handled
inconsistently. This affects `Table.update(values={...})` /
`merge_insert` when a struct column has a field name containing `'`.

### Fix

Render the key through `value_to_sql(str(k))` so field names are escaped
exactly like string values:

```python
>>> value_to_sql({"it's": 1})
"named_struct('it''s', 1)"
```

Keys without special characters are unchanged (`'a'` stays `'a'`), so
existing behavior is preserved.

### Verification

```
$ pytest python/tests/test_util.py -k value_to_sql_dict
```

The new `test_value_to_sql_dict_key_escaping` covers quoted keys (incl.
nested structs) and fails on `main` (`named_struct('it's', 1)`), passes
with this change; the existing `test_value_to_sql_dict` still passes.

Ghxst ☠️ 394bb34fa2 fix(rust): report local write progress bytes from Lance (#3422) 
Fixes #3360.

This updates native table writes so local write progress uses Lance
writer byte stats instead of Arrow in-memory batch size once write bytes
are available. The change wires the existing `WriteProgressTracker` into
`InsertExec` for native `add` writes, installs a Lance `WriteProgressFn`
only when no lower-level callback is already configured, and keeps the
existing public `InsertExec::new` signature unchanged.

Validation:

Armaan Sandhu b2ae763254 fix(python): raise clear TypeError for bare List/Tuple in pydantic schema conversion (#3511) 
Closes #3502

## Problem

A bare, unparameterised `typing.List` / `typing.Tuple` field crashes
`to_arrow_schema` with an opaque `AttributeError: __args__`:

```python
from typing import Tuple
from lancedb.pydantic import LanceModel

class Doc(LanceModel):
    items: Tuple

Doc.to_arrow_schema()  # AttributeError: __args__
```

In `_py_type_to_arrow_type`, the branch `elif getattr(py_type,
"__origin__", None) in (list, tuple)` is taken for a bare generic (its
`__origin__` is `list / tuple`), but the next line reads
`py_type.__args__[0]`, and a bare generic has no `__args__`. Other
unsupported types (e.g. `Dict[str, int]`) correctly raise a clear
`TypeError`, so this case is inconsistent.

Fix

Guard the element-type lookup with `getattr(py_type, "__args__", None)`
and raise a clear `TypeError` when it is missing, matching the existing
behavior for other unsupported types. Bare builtin list / tuple are
unaffected (their `__origin__` is `None`, so they already fall through
to the existing `TypeError`).

Testing

- Added `test_bare_generic_raises_type_error` covering both `List` and
`Tuple`.
- ruff format and ruff check clean.

Drew Gallardo 1bead6960c fix: pin mock clock in eventual consistency test (#3547) 
This PR fixes a flaky test I hit on Windows test in #3528.

Looks like `test_eventual_consistency_background_refresh` was failing
with `v_cached` expected 1, got 2. There was a pr which swapped
`tokio::time::sleep(300ms)` for `clock::advance_by(300ms)`, which is
pretty much fine but the test necer pinned the clock so the first
`get()` locks the `cached_at` on wall time. Therefore, if our CI is
taking long enough the ttl expires before the value assertion in the
test.

So now we can add a `pin()` and call it first `get()`. After that we can
advance the clock manually with no problems.

Also, it's worth noting that I tried pinning in `BackgroundCache::new()`
first. That broke another test `test_reload_resets_consistency_timer`,
which uses real `tokio::time::sleep` and needs wall clock after
`clear_mock()`. So the pin stays in this test only. And this should
unblock us.

Brendan Clement 0abf641733 feat: send read-freshness signal on the lance-namespace path (#3551) 
### Description

`db://`-style connections that use the lance-namespace path
(`LanceNamespaceDatabase` → `NativeTable` + the lance-namespace REST
client) never sent a read-freshness signal. Against a server configured
to serve cached table metadata up to some staleness window, this allows
stale-read-after-write across handles and processes. The remote table
path already solved this (#3439). This brings the namespace path to
parity.

The namespace REST client doesn't let callers attach headers directly,
but it forwards a `DynamicContextProvider`'s `headers.*` context entries
as HTTP headers per request. So:

- A shared per-table baseline map is created before the namespace
client. I built and installed on the `ConnectBuilder` via a context
provider.
- On read operations the provider emits ·x-lancedb-min-timestamp =
max(baseline, now − read_consistency_interval)`
  (RFC3339), keyed by the operation's `object_id`.
- Each table handle bumps its baseline (monotonically) on
`checkout_latest()`, `restore()`, and every data/schema write.
`checkout_latest()` is the primary hook: consumers refresh a handle
there after writing elsewhere, then poll.

Read operations that carry the floor: `describe_table`,
`list_table_versions`, `query_table`, `list_tables`.
`list_table_versions` is what resolves "latest" for managed-versioning
tables (`get_latest_version`), so it's the op that makes
`checkout_latest()` actually observe a prior write.
`describe_table_version` is excluded (pinned to an immutable version).
This mirrors #3439 (timestamp baseline, `max(baseline, now − interval)`,
monotonic); no `min_version` and no body channel, since the namespace
path has no version-returning write responses.

### Testing

- Unit tests for `compute_min_timestamp` / `next_freshness_baseline` and
the provider (header at/after a bumped baseline; nothing for an empty
baseline + no interval; interval floor applies; non-read ops emit
nothing; `list_tables` uses only the interval floor).
- Verified end-to-end against a local server that honors the header:
reads carry `x-lancedb-min-timestamp`, writes don't, and read-your-write
holds.

Yang Cen 976edeb2ff feat(query): add approx mode to vector queries (#3549) 
## Feature

### What is the new feature?

Adds Rust core API support for configuring vector query approximation
mode with `ApproxMode::{Fast, Normal, Accurate}`.

### Why do we need this feature?

Lance already exposes `lance_index::vector::ApproxMode` and scanner
support for controlling the speed/accuracy tradeoff for approximate
vector search. LanceDB Rust queries need to expose and pass this setting
through for local/native and remote vector searches.

### How does it work?

- Adds public `ApproxMode` in `rust/lancedb`, with lowercase serde,
`Default::Normal`, parse/display, and conversions to/from Lance's
`ApproxMode`.
- Adds `approx_mode: Option<ApproxMode>` to `VectorQueryRequest` and a
`VectorQuery::approx_mode(...)` builder.
- Applies the mode to native/local Lance scanners after `nearest(...)`
when explicitly set.
- Sends `approx_mode` in remote query JSON only when explicitly set;
default requests omit it.

## Validation

- `cargo fmt --all`
- `cargo test --quiet --features remote approx_mode`
- `cargo test --quiet --features remote
test_query_vector_default_values`
- `cargo check --quiet --features remote --tests --examples`

Brendan Clement f76b075d13 feat: add table branch support to remote tables and Python/TS bindings (#3540) 
### Description
Adding branch support for RemoteTable by threading a branch selector
onto every operation the data plane accepts it on. Exposes the
currentBranch to nodejs and python through the bindings.

Matching the server handlers, the branch rides as:
- a `?branch=` query parameter for Arrow-body and query-only ops
(insert, merge_insert, multipart_*, version/list, drop_index)
- a `branch` field in the JSON body for everything else (count_rows,
query, update, delete, create_index, column ops, index list/stats,
stats, restore, describe, tags create/update)

A main-branch handle (`branch == None`) produces byte-identical requests
to before: no `branch` field and no `?branch=`

- Handle-per-branch: `create_branch` / `checkout_branch` return a new
handle with fresh caches and reset version/freshness state, mirroring
`NativeTable`.
- `create_branch` maps 409 to already-exists, 400 to invalid, and 404 to
not-found with source context, and sends without retry so the 409 stays
observable.
- `Ref` translation covers version, version-number (relative to the
handle's branch), and tag (resolved via the tags endpoint); `"main"` and
empty normalize to the main branch.
- Python branch handles persist their branch (and pinned version) across
pickle/fork, so a forked or pickled handle reopens on its branch rather
than silently reverting to main.

### Tests

- Rust mock tests per op category (query-param and body mechanisms,
branch CRUD, error paths, backward-compat).
- Python sync branch CRUD, `open_table(branch=)`, and a pickle
round-trip regression test.

Will Jones 6219975222 perf: drop N+1 in RemoteTable::list_indices (#3535) 
`RemoteTable::list_indices` currently makes one `/index/list/` call plus
one `/index/{name}/stats/` call per index just to recover `index_type`.

When the server returns `index_type` directly in the `/index/list/`
response, all enriched fields are used and the per-index stats fan-out
is skipped entirely. When `index_type` is absent (legacy servers), the
existing stats fallback runs as before. This is content-based: no
version header required.

## Changes

- `RemoteTable::parse_index_list_response` replaces the old split
between enriched and legacy parsers. A single struct deserializes both
old and new response shapes, with all fields except `index_name` and
`columns` optional. `index_type` acts as the sentinel: present → use
enriched fields directly; absent → call `/index/{name}/stats/`.

## Tests

Added `test_list_indices_enriched` covering:
- All enriched fields populated correctly when `index_type` is in the
list response
- Optional fields absent from the response deserialize as `None`
- Stats endpoint is **not** called (panics if hit), verifying the
fan-out is eliminated

Existing `test_list_indices` and `test_list_indices_nested_field_paths`
exercise the legacy path unchanged.

## Depends on

- #3497 (expand `IndexConfig`) — already merged
- Server-side enriched response support

Closes #3494

- Moves 8 `NativeTable` inherent methods (`load_indices`,
`validate_index_type`, `build_ivf_params`, `get_num_sub_vectors`,
`get_vector_dimension`, `resolve_index_field`, `make_index_params`,
`get_index_type_for_field`) and 11 associated tests into the new module.
- Reduces `table.rs` from ~5009 to ~3804 lines (-1205 lines) with no
behavioral changes.

Will Jones f8caef3aca feat(bindings): expose new IndexConfig fields in Python and Node.js (#3534) 
## Summary

Surfaces the rich per-index metadata added in #3497 to the Python and
Node.js language bindings. Closes #3495.

New optional fields exposed on `IndexConfig` in both bindings:

- `index_uuid` / `indexUuid` — UUID of the first index segment
- `type_url` / `typeUrl` — protobuf type URL for the index
- `created_at` / `createdAt` — creation timestamp (milliseconds since
Unix epoch)
- `num_indexed_rows` / `numIndexedRows` — rows covered by the index
- `num_unindexed_rows` / `numUnindexedRows` — rows not yet indexed
- `size_bytes` / `sizeBytes` — total index file size in bytes
- `num_segments` / `numSegments` — number of index segments
- `index_version` / `indexVersion` — on-disk format version
- `index_details` / `indexDetails` — type-specific JSON details string

All fields are `None`/`undefined` for remote tables (which don't yet
surface this metadata through the server response).

## Changes

- `python/src/index.rs`: extend `IndexConfig` pyclass; update `From`
impl; update `__getitem__`
- `python/python/lancedb/_lancedb.pyi`: add type hints for new fields
- `python/python/tests/test_table.py`: new `test_index_config_fields`
test
- `nodejs/src/table.rs`: extend `IndexConfig` napi struct; update `From`
impl
- `nodejs/__test__/table.test.ts`: new test; update existing `toEqual`
assertions to `expect.objectContaining` to accommodate new fields

## Test plan

- [x] Python: `uv run --extra tests pytest
python/tests/test_table.py::test_index_config_fields`
- [x] Node.js: `pnpm test __test__/table.test.ts`

nuthalapativarun 40f3e22600 feat: support rename_table on LanceNamespaceDatabase (#3520) 
## Summary

Closes #3412

Implements `rename_table` for `LanceNamespaceDatabase` (sync and async
Python) and the Rust `NamespaceDatabase` backend. Previously these
raised `NotImplementedError`; this PR delegates to the
`LanceNamespace.rename_table` method which is part of the
lance-namespace spec.

### Changes

- **`rust/lancedb/src/database/namespace.rs`**: Remove the
`NotImplementedError` stub for `rename_table`. Build a
`RenameTableRequest` (with `id`, `new_table_name`, and optionally
`new_namespace_id`) and call `self.namespace.rename_table(...)`,
mirroring the existing `drop_table` pattern.

- **`python/python/lancedb/namespace.py`**: Import `RenameTableRequest`
from `lance_namespace`. Replace the `raise NotImplementedError` in both
`LanceNamespaceDatabase.rename_table` (sync) and
`AsyncLanceNamespaceDatabase.rename_table` (async) with a call to
`self._namespace_client.rename_table(request)`.

- **`python/python/tests/test_namespace.py`**: Replace the
`test_rename_table_not_supported` test (which checked for
`NotImplementedError`) with `test_rename_table`, which:
  1. Creates a table in a namespace
2. Calls `rename_table` with `cur_namespace_path` and
`new_namespace_path`
  3. Asserts the old name is gone from `table_names()`
  4. Asserts the new name appears in `table_names()`
  5. Verifies the renamed table can be opened

## Test plan

- [ ] Existing namespace tests pass in CI (all rely on
`lance.namespace.DirectoryNamespace` which requires the full lance
package)
- [ ] `test_rename_table` exercises the full rename path: create →
rename → verify old gone → verify new present → open
- [ ] Rust build passes with the updated `namespace.rs` (requires Rust
toolchain in CI)

nuthalapativarun 04480c274a test(python): add nested field regression matrix tests (#3518) 
## Summary

Closes #3406

Add a regression matrix in `python/python/tests/test_nested_fields.py`
that exercises the full nested field index lifecycle for both the sync
and async Python table APIs. The tests will fail if any implementation
regresses to leaf-only field names in `list_indices`, `index_stats`,
search, or filter results.

## Test scenarios covered

**Index types:** BTree scalar, IvfPq vector, FTS

**Field-name edge cases (per acceptance criteria):**
- `rowId` — camelCase top-level field
- `` `row-id` `` — hyphenated top-level field (escaped)
- `parent.`\``leaf.name`\`` ` — struct leaf whose name contains a
literal dot
- `MetaData.userId` — mixed-case nested path
- `` `meta-data`.`user-id` `` — hyphenated struct with hyphenated leaf

**Lifecycle operations per index type:**
- `create_index` / `create_scalar_index` / `create_fts_index`
- `list_indices` → verify canonical full dotted path (not leaf name)
- `index_stats` → verify row count and index type
- Filtered scan (`WHERE nested.field = value`)
- Vector search via nested embedding column
- FTS search via nested text column
- `add` (append) then re-check index listing
- `optimize` then re-check index listing

**Both sync and async APIs** are covered in parallel test classes.

## Notes

Lance forbids top-level field names that contain a literal `.`, so the
`` `a.b` `` acceptance-criterion variant is exercised as a *struct leaf*
field (`parent.`\``leaf.name`\``) rather than a top-level column.

Will Jones f03abc27e3 feat: expand IndexConfig with rich per-index metadata (#3497) 
`IndexConfig` (returned by `Table::list_indices`) previously exposed
only `name`, `index_type`, and `columns`. Lance's `describe_indices`
provides richer per-index info cheaply (reads manifest metadata, often
cached), so this surfaces it.

Adds these `Option<T>` fields to `lancedb::index::IndexConfig`,
populated in `NativeTable::list_indices` from the `IndexDescription`:

- `index_uuid`: uuid of the first segment
- `type_url`: protobuf type URL (`IndexDescription::type_url`)
- `created_at`: minimum creation time across segments
- `num_indexed_rows`: approximate rows indexed across segments
- `num_unindexed_rows`: table row count minus `num_indexed_rows`
- `size_bytes`: total size of index files across segments
- `num_segments`: number of segments making up the index
- `index_version`: on-disk index format version (first segment)
- `index_details`: index-type-specific details as JSON

This field set mirrors the lance-namespace `IndexContent` contract
(lance-format/lance-namespace#348) so client and server agree on the
same shape. Note these are populated **locally** via `describe_indices`
— `NativeTable::list_indices` reads the dataset directly and does not
depend on the namespace spec change.

`RemoteTable` leaves the new fields `None` until a follow-up wires them
through the server response (#3494). Bindings exposure will also be a
follow up: #3495

Existing `list_indices` tests in `rust/lancedb/src/table.rs` are
extended to assert the new fields.

Jack Ye 8373318e89 feat: support FM-Index scalar index for substring search (#3532) 
Adds an FM-Index — a scalar index over string and binary columns that
accelerates substring search (`contains(col, 'needle')`), distinct from
the tokenized `FTS` index — across the Rust core and the Python and
TypeScript bindings.

## Rust

- `Index::Fm(FmIndexBuilder)` and `IndexType::Fm`.
- `make_index_params` maps `Index::Fm` to Lance's
`ScalarIndexParams::for_builtin(BuiltinIndexType::Fm)`.
- `supported_fm_data_type` validates
`Utf8`/`LargeUtf8`/`Binary`/`LargeBinary` columns.
- `list_indices` round-trips the type (`"Fm"` → `IndexType::Fm`); the
remote wire type is `"FM"`.

## Python

Adds `lancedb.index.Fm`, accepted by `create_index`:

```python
from lancedb.index import Fm

await tbl.create_index("text", config=Fm())
```

## TypeScript

Adds the `Index.fm()` factory:

```ts
await tbl.createIndex("text", { config: Index.fm() });
```

Xuanwo 566b67a634 fix: support LargeList label list indexes (#3529) 
## Summary

This PR extends nested-field regression coverage across Rust
local/remote, Python sync/async, and Node so canonical escaped paths
stay consistent across scalar, vector, and FTS index lifecycle behavior.

It also aligns LanceDB's LabelList type gate with Lance by accepting
`LargeList<primitive>` columns while keeping `List<Struct<...>>`
unsupported until Lance defines stable membership semantics for struct
labels.

Part of #3406.

nuthalapativarun 9c12fb6437 fix(nodejs): treat NAPI_RS_FORCE_WASI as truthy only when set to 'true' (#3519) 
## Summary

Fixes the `NAPI_RS_FORCE_WASI=false` issue by upgrading `@napi-rs/cli`
from `3.5.1` to `3.7.0`.

Closes #3267

## Root Cause

In the `native.js` loader generated by `napi build`, the check was:

```js
if (!nativeBinding || process.env.NAPI_RS_FORCE_WASI) {
```

In JavaScript, any non-empty string is truthy, so
`NAPI_RS_FORCE_WASI=false` (a non-empty string) inadvertently triggered
the WASI fallback path. This caused an `ENOENT` error when
`lancedb.wasi.cjs` was not present.

## Fix

`@napi-rs/cli@3.7.0`
([napi-rs/napi-rs#3236](https://github.com/napi-rs/napi-rs/pull/3236))
introduced a tri-state check in the template that generates `native.js`:

**Before (generated by @napi-rs/cli@3.5.1):**
```js
if (!nativeBinding || process.env.NAPI_RS_FORCE_WASI) {
```

**After (generated by @napi-rs/cli@3.7.0):**
```js
const forceWasi =
  process.env.NAPI_RS_FORCE_WASI === 'true' || process.env.NAPI_RS_FORCE_WASI === 'error'

if (!nativeBinding || forceWasi) {
```

Only the literal string `'true'` (or `'error'` for strict mode) now
activates the WASI path. All other values, including `'false'`, `'0'`,
or an unset variable, behave as if WASI is not forced.

## Changes

- `nodejs/package.json`: bump `@napi-rs/cli` from `3.5.1` to `3.7.0`
- `nodejs/package-lock.json` / `nodejs/pnpm-lock.yaml`: update lock
files to match

The fix is in the upstream napi-rs tool; the generated `native.js` is
not committed to this repository and is produced at build time by `napi
build`.

devteamaegis f260d3bf12 fix(util): convert numpy scalars in value_to_sql (#3522) 
## What's broken

`Table.update(values={...})` raises `NotImplementedError: SQL conversion
is not implemented for this type` when a value is a numpy scalar such as
`np.int64`, `np.int32`, `np.float32`, or `np.bool_`. These arise
naturally from indexing an ndarray or a pandas int/bool column.
`np.float64` happens to work (it subclasses `float`), which makes the
failure inconsistent and surprising.

```python
df = pd.DataFrame({"id": np.array([10, 20], dtype="int32")})
t.update(where="id = 1", values={"id": df["id"].iloc[0]})   # np.int32
# -> NotImplementedError: SQL conversion is not implemented for this type
```

## Why it happens

`value_to_sql` is a `singledispatch` with handlers only for native
Python types and `np.ndarray`; numpy `integer`/`floating`/`bool_`
scalars aren't Python subclasses, so they fall through to the
`NotImplementedError` base.

## Fix

Register handlers for `np.bool_`, `np.integer`, and `np.floating` that
delegate to the existing native handlers.

## Test

`value_to_sql` on `np.int32/int64/float32/float64/bool_` all convert;
`np.int32` raised before.

Brendan Clement d9018067b3 feat: support checking out a version on a branch (#3504) 
### Description

Stacked on #3490. Adds an optional version to branch checkout across the
Rust core and the Python and TypeScript SDKs, so you can open a specific
version on a branch ("version V of branch B"), not just the branch's
latest version

Rust

```rust
// Open version 3 of branch "exp" (a read-only view): check out from an
// existing table, or open it directly from the connection.
let exp_v3 = table.checkout_branch("exp", Some(3)).await?;
let exp_v3 = db.open_table("items").branch("exp").version(3).execute().await?;
// checkout_latest re-attaches to the branch's writable HEAD.
exp_v3.checkout_latest().await?;

// With no branch, a version opens main at that version.
let main_v3 = db.open_table("items").version(3).execute().await?;
```

Python

```python
# Open version 3 of branch "exp" (a read-only view): check out from an
# existing table, or open it directly from the connection.
branch_v3 = await table.branches.checkout("exp", version=3)
branch_v3 = await db.open_table("items", branch="exp", version=3)
# checkout_latest re-attaches to the branch's writable HEAD.
await branch_v3.checkout_latest()

# With no branch, a version opens main at that version.
main_v3 = await db.open_table("items", version=3)
```

TypeScript

```typescript
// Open version 3 of branch "exp" (a read-only view): check out from an
// existing table, or open it directly from the connection.
const branchV3 = await (await table.branches()).checkout("exp", 3);
const opened = await db.openTable("items", undefined, { branch: "exp", version: 3 });
// checkoutLatest re-attaches to the branch's writable HEAD.
await branchV3.checkoutLatest();

// With no branch, a version opens main at that version.
const mainV3 = await db.openTable("items", undefined, { version: 3 });
```

### Testing
- Added unit tests (Rust, Python sync + async, TypeScript):
branch-scoped resolution at a version number shared with `main` and with
another branch, read-only enforcement on a pinned handle,
`checkout_latest` recovery to the branch's HEAD, fork-point reads, and
the nonexistent-version/branch error paths.
- Ran smoke tests against the Python and TypeScript SDKs on local
machine.

Brendan Clement 53517b3aaa feat: add table branch support (#3490) 
### Description

Adds first-class support for table branches across the Rust core and the
Python and TypeScript SDKs.

Rust

```rust
use lance::dataset::refs::Ref;

// Create a branch from main and write to it — main is untouched.
let exp = table.create_branch("exp", Ref::Version(None, None)).await?;
exp.add(batches).await?;

// Reopen the branch later: check out from a table, or open it directly.
let exp = table.checkout_branch("exp").await?;
let exp = db.open_table("items").branch("exp").execute().await?;

let branches = table.list_branches().await?;
table.delete_branch("exp").await?;
```

Python

```python
# Create a branch from main and write to it
branch = await table.branches.create("exp", from_ref="main")
await branch.add(data)

# Reopen the branch later: check out from a table, or open it directly.
branch = await table.branches.checkout("exp")
branch = await db.open_table("items", branch="exp")

await table.branches.list()
await table.branches.delete("exp")
```

TypeScript

```typescript
const branches = await table.branches();

// Create a branch from main and write to it
const branch = await branches.create("exp");
await branch.add(data);

// Reopen the branch later: check out from a table, or open it directly.
const checkedOut = await branches.checkout("exp");
const opened = await db.openTable("items", undefined, { branch: "exp" });

await branches.list();
await branches.delete("exp");
```

### Testing
- Added unit tests
- ran smoke tests against python and typescript sdks on local machine


### Next steps
- Add RemoteTable support
- Add Branch Comparison support
- Merge Branching support

Yang Cen 3e25f584eb fix(python): push down namespace full reads (#3516) 
## Bug Fix

### What is the bug?

Namespace-backed `LanceTable.to_arrow()` full-table reads bypassed the
existing `QueryTable` server-side query path and called the lower-level
table `to_arrow()` implementation directly. In Geneva/Sophon this could
fail while parsing the Arrow IPC response for
`hist.get_table().to_arrow()` / `to_pandas()`, even though
`hist.get_table().search().to_arrow()` worked.

### What issues or incorrect behavior does the bug cause?

Full-table reads on namespace-backed tables with `QueryTable` pushdown
could fail with Arrow IPC parse errors, while query/search reads on the
same table succeeded. Since `to_pandas()` delegates through `to_arrow()`
for non-blob/native cases, pandas export was affected too.

### How does this PR fix the problem?

When `QueryTable` pushdown is enabled, sync and async table `to_arrow()`
now construct a plain no-filter, no-limit, all-columns query and execute
it through the table-level `_execute_query()` path. `AsyncTable` now
preserves namespace context from async namespace connections so async
full reads can make the same pushdown decision. Non-namespace tables and
namespace tables without `QueryTable` pushdown keep their existing
behavior.
