d1d77a8d96 chore: allow CDDL-1.0 for inferno dev dependency (pending legal review)
Lance v8.0.0-beta.2 pulls in inferno v0.11.21 (CDDL-1.0) transitively via
pprof -> lance-testing, a dev/profiling-only dependency that is not
distributed. Add CDDL-1.0 to the deny.toml allow list so cargo-deny passes.

415d199c15 feat(rust): support datafusion expressions for merge insert predicates (#3444)
### Description
This PR exposes native DataFusion expression support in the Rust SDK's
`MergeInsertBuilder` via two new builder methods:
`when_matched_update_all_expr` and
`when_not_matched_by_source_delete_expr`.

For remote LanceDB tables (where operations are serialized over
HTTP/JSON to the SaaS backend), native DataFusion expression trees
cannot be executed directly. The SDK handles this gracefully by
returning a `NotSupported` error.

### Key Changes
- **`MergeFilter` Enum**: Introduced a helper enum to store either a SQL
string or a native `datafusion_expr::Expr`.
- **`MergeInsertBuilder`**: Updated `when_matched_update_all_filt` and
`when_not_matched_by_source_delete_filt` fields to store the new enum,
and added `when_matched_update_all_expr` and
`when_not_matched_by_source_delete_expr` builder methods.
- **Execution & Remote Dispatch**: Dispatched the filter variants during
local execution, and rejected expression filters with a clean
`NotSupported` error in remote table request conversion.
- **Testing**: Added a `test_merge_insert_expr` unit test covering
conditional updates and deletes with programmatically built DataFusion
expressions.

### Verification
- Added integration test `test_merge_insert_expr` which successfully
compiles and passes.
- Formatted and linted the code.

Closes #3416

4e44262499 test(python): add regression test for nullable struct with None (#2654) (#3483)
## Summary

Regression test for [issue
#2654](https://github.com/lancedb/lancedb/issues/2654) — a nullable
struct column whose first batch contains only `None` values crashed in
`_align_field_types` with `AttributeError: 'pyarrow.lib.DataType' object
has no attribute 'fields'`.

The actual fix landed in #3394, but no test was added. This PR adds the
reproducer from the issue as a test.

## Test plan

- `test_add_nullable_struct_with_none`: creates a table with a nullable
struct column, adds a row with a non-null struct value, then a row with
`None` for the struct field. Verifies both rows land correctly.
- Uses Lance file format v2.1 (`new_table_data_storage_version="2.1"`)
because nullable structs aren't supported on v2.0.

632375faf1 docs: add cross-SDK parity guidance for code review (#3464)
Adds a REVIEW.md at the repo root with cross-SDK parity guidance for
automated code review. The Claude Code review feature automatically
loads `REVIEW.md` as review-only context.

This is intentionally a semantic nudge, not a deterministic check, it
relies on the reviewer reading the sibling SDK, so it will catch most
gaps.

9969191d0d fix(rerankers): guard against empty vector_results in RRFReranker.rerank_multivector (#3467)
## What's broken

Calling `RRFReranker().rerank_multivector([])` crashes with `IndexError:
list index out of range` because the method accesses `vector_results[0]`
for the type-homogeneity check before verifying the list is non-empty.
The `all()` call passes vacuously on an empty iterable so the crash hits
the next lines.

```python
from lancedb.rerankers import RRFReranker
RRFReranker().rerank_multivector([])
# IndexError: list index out of range
```

## Why it happens

The type check uses `vector_results[0]` as the reference type but never
guards against an empty list. `all(...)` short-circuits to `True` when
the iterable is empty, so the bad index access on the lines that follow
is never reached by the existing guard logic.

## Fix

Add an explicit empty-list check before any indexing.

1e7326cd8c fix(rerankers/mrr): raise ValueError on empty vector_results list (#3469)
## What's broken

`MRRReranker.rerank_multivector([])` raises `IndexError: list index out
of range`. The crash happens on line 128 (the `all()` type-homogeneity
check passes vacuously on an empty iterable) and on line 134 which
accesses `vector_results[0]` unconditionally, with no prior guard for an
empty list.

## Why it happens

`all()` over an empty iterable returns `True`, so the type check
silently passes and execution falls through to `vector_results[0]` which
crashes.

## Fix

Added a two-line guard at the top of `rerank_multivector` that raises a
clear `ValueError("vector_results must not be empty")` before any
indexing occurs.

## Test

Added `test_mrr_reranker_empty_input` in `test_rerankers.py` which calls
`rerank_multivector([])` and asserts that a `ValueError` with the
message "must not be empty" is raised.

Fixes #3468

6f18eb4cce feat(python): support blob modes in query to_pandas (#3487)
## Feature

- What is the new feature?
- Adds `blob_mode` support to sync and async Python query `to_pandas()`
APIs.
- Enables plain scan queries to return blob columns as lazy `BlobFile`
objects, raw bytes, or blob descriptions.
- Lets namespace-backed local tables use Lance native blob-aware pandas
conversion for lazy blobs.

- Why do we need this feature?
- Table and Lance dataset/scanner APIs already support blob-aware pandas
conversion, but LanceDB query builders did not expose that capability.
- Geneva and other callers should be able to use query-level
`to_pandas(blob_mode=...)` without manually constructing Lance scanners.

- How does it work?
- Plain scan queries route through Lance scanner native
`to_pandas(blob_mode=...)`, preserving filter, projection, limit,
offset, row id, and alias/expression projection behavior.
- Non-native query shapes keep existing Arrow fallback semantics and
raise a clear error when they return blob columns with
`blob_mode="lazy"` or `blob_mode="bytes"`.
- Focused tests cover table/query blob modes,
filter/select/limit/offset/alias query cases, async query behavior,
vector-query error boundaries, and namespace-backed lazy blobs.

## Validation

- `cd python && .venv/bin/maturin develop --uv --extras tests,dev
--profile dev`
- `cd python && uv run --frozen --no-sync pytest

# Code review guidelines
Repo-specific guidance for automated PR reviews.
## Cross-SDK parity
LanceDB exposes the same core (`rust/lancedb`) through Python, TypeScript (`nodejs`),
and Java bindings. Behavioral drift between SDKs is a recurring problem, so watch for
parity gaps when reviewing — but only flag real ones:
* If the change adds or modifies user-facing API or behavior in the shared core
(`rust/lancedb`), check whether each binding that should expose it (`python`,
`nodejs`) does. A core change with no corresponding binding update is worth a note.
* If the change adds or modifies a public API in one SDK but not the other, open the
sibling SDK's corresponding module and state whether an equivalent exists. If not,
note it as a possible parity gap and suggest a follow-up issue.
* For bug fixes, first read the sibling SDK's analogous code path to check whether the
same bug exists there. Only raise parity if it actually does. Do not ask to "port" a
fix for a bug that only ever existed in one binding.
* Stay silent on internal-only refactors, tests, docs, and changes with no cross-SDK
surface.
* Parity expectations apply to the Python and TypeScript (`nodejs`) SDKs. Java currently
implements only the remote table, not the local/embedded backend, so it is expected to
be partial — do not flag Java for missing local-only functionality.
* Keep parity feedback to a short, clearly-labeled note (e.g. "Possible SDK parity
gap: …"). It is advisory, not a merge blocker.
