 ### Documentation
 * New features must include updates to the rust documentation comments. Link to
  relevant structs and methods to increase the value of documentation.
+
+## Cursor Cloud specific instructions
+
+The VM snapshot already has the Rust `1.97.0` toolchain (auto-selected by
+`rust-toolchain.toml`), `protoc`, `uv` (on `PATH` via `~/.bashrc`), the Rust
+debug build artifacts, the Python editable extension, and `nodejs/node_modules`.
+The startup update script only refreshes dependencies (`uv sync` for Python and
+`pnpm install` for Node); it deliberately does NOT rebuild the native
+extensions. After changing Rust or PyO3/napi binding code you must rebuild the
+affected binding yourself (see per-binding rebuild commands below).
+
+Non-obvious caveats discovered during setup:
+
+* The documented Python bootstrap `uv run --extra tests --extra dev maturin
+  develop --extras tests,dev` does not work as-is here: `maturin` is not
+  installed as a CLI in the uv environment, and `maturin develop --extras`
+  runs its own dependency resolution that cannot find the prerelease
+  `pylance==9.0.0rc1` (it lacks the extra package index that `uv` uses via
+  `uv.lock`). Because `uv run --extra tests --extra dev` already installs those
+  extras, the working command is:
+  `cd python && uv run --extra tests --extra dev --with maturin maturin develop`
+  (note: `--with maturin`, and no `--extras`). This is the Python binding
+  rebuild command.
+* Rust core, the Python extension (maturin), and the Node addon (napi) all
+  compile into the SHARED `/workspace/target`. Cargo feature unification differs
+  between `maturin develop` and `pnpm build`, so alternating between building
+  the Python and Node bindings forces a full recompile of shared crates
+  (`lancedb`, `datafusion`, `lance-*`) — roughly 6-7 min each way on this
+  4-core VM. Build one binding at a time to avoid the churn.
+* The `_lancedb` release build (triggered when `uv run`/`uv sync` installs the
+  `lancedb` project itself) uses `lto = "fat"` + `opt-level = 3`, needs ~11 GB
+  RAM, and takes ~20 min cold on this VM. To avoid it, the update script uses
+  `uv sync --no-install-project --inexact` (the `--inexact` flag is required so
+  the sync does not uninstall the editable extension). Prefer the debug
+  `maturin develop` (~6 min cold, seconds when warm) for iteration.
+* `cargo check` only produces metadata, so the first `cargo run --example ...`
+  or `cargo test` after a check triggers a large codegen/link compile.
+* Node binding rebuild: `cd nodejs && pnpm build` (napi debug build + `tsc`).
+  The native addon lands at `nodejs/dist/lancedb.linux-x64-gnu.node`.
+
+Verified working (local backend, no cloud credentials needed):
+
+* Rust: `cargo check/clippy --features remote --tests --examples`,
+  `cargo test --features remote -p lancedb --lib`, `cargo run --features remote
+  --example simple`.
+* Python: `cd python && uv run --extra tests pytest python/tests/test_table.py`,
+  `uv run --directory python --extra dev ruff check python`.
+* Node: `cd nodejs && pnpm lint`, `pnpm test __test__/connection.test.ts`.
+
+Java (`java/`) is optional; its integration tests need LanceDB Cloud
+credentials (`LANCEDB_DB`, `LANCEDB_API_KEY`) and were not set up here.

-## MemWAL LSM write path
-
-Most table operations reach LanceDB through the `LanceNamespace` above, which is
-generated from the Lance Namespace specification. The MemWAL LSM routes are not part
-of that specification, so they are issued through a separate client:
-
-```java
-import com.lancedb.LanceDbRestClient;
-import com.lancedb.LanceDbTableLsm;
-import com.lancedb.LsmWriteSpec;
-
-LanceDbRestClient client = LanceDbNamespaceClientBuilder.newBuilder()
-    .apiKey("your_lancedb_cloud_api_key")
-    .database("your_database_name")
-    .buildRestClient();
-
-LanceDbTableLsm lsm = new LanceDbTableLsm(client, "my_table");
-
-// Route future merge_insert upserts through the MemWAL, hash-bucketed by `id`.
-lsm.setLsmWriteSpec(LsmWriteSpec.bucket("id", 16));
-
-// ... merge_insert traffic ...
-
-// Converge the fresh tier into the base table.
-lsm.checkpointLsm();
-
-// Inspect live per-bucket state.
-lsm.getLsmStats().ifPresent(stats -> stats.buckets().forEach(bucket ->
-    System.out.println(bucket.shardId() + ": " + bucket.generations().size() + " L0 generations")));
-
-client.close();
-```
-
-`maintainedIndexes` is tri-state, and the null default is the opposite of what a Java
-reader usually expects:
-
-| Value | Meaning |
-| --- | --- |
-| unset (null) | Maintain **every** index the MemWAL can, resolved on install |
-| `Collections.emptyList()` | Maintain **none** |
-| `Arrays.asList("id_idx")` | Maintain exactly those |

        Maximum number of transforms to run concurrently.  Must be greater
        than zero.  When ``None`` (the default), uses ``os.cpu_count()`` or 1
        when the CPU count is unavailable.
-    on_transform_error:
-        What to do when the transform raises an exception:
-
-        - ``"raise"`` (the default): the exception propagates and iteration
-          aborts.
-        - ``"skip"``: the failing rows are dropped and iteration continues.
-        - ``"warn"``: like ``"skip"``, but a warning is logged for each
-          failing batch.
-        - a callable ``handler(exc) -> bool``: called with the exception;
-          return ``True`` to skip the failing rows or ``False`` to re-raise.
-          Useful to skip only expected error types (compatible with
-          ``webdataset.handlers`` style handlers).
-
-        When a batch fails, the transform is re-invoked on each single-row
-        slice of the batch so that only the rows that actually fail are
-        dropped.  Transforms should therefore be deterministic and accept
-        batches of any size (including one row).  Skipped rows are counted in
-        ``rows_skipped``.
-
-        Skipping weakens the elastic-determinism guarantee at the end of the
-        epoch: splits that lose more rows than others run dry earlier, and
-        each rank's iterator ends at the last cycle where every split *it
-        owns* still has a row.  Because bad rows are not distributed evenly
-        across splits, this means one rank's iterator can yield noticeably
-        fewer or more steps than another rank's *in the same run* — there is
-        no cross-rank coordination that stops every rank at the same global
-        step.  This is generally safe for asynchronous or single-rank use,
-        but synchronous distributed training (e.g. ranks that call
-        ``all_reduce`` every step) can hang or deadlock if one rank's
-        iterator is exhausted while others are still stepping; callers doing
-        synchronous multi-rank training with ``on_transform_error != "raise"``
-        are responsible for their own cross-rank stopping mechanism (e.g.
-        broadcasting a stop signal on ``StopIteration``).  The final few
-        global steps can also differ across topologies (bounded by the skew
-        in bad-row counts across splits).  The sequence of samples yielded
-        from each split remains deterministic.  Mid-epoch
-        checkpoints remain exact provided the transform fails
-        deterministically; in multi-rank training each rank must save its
-        own ``state_dict`` and the states must be combined with
-        ``merge_state_dicts`` before resuming on a different topology.
-        Prefer the ``filter`` parameter when bad rows can be expressed as a
-        SQL predicate (e.g. ``"col IS NOT NULL"``) — filtering happens before
-        splits are built, so every guarantee is fully preserved.

-// outside the timed section. Defaults intentionally cover 1k, 10k, and 100k siblings
-// with 10 warmups and 100 distinct missing-table opens per scale:

-// ```text

-//
-// `BENCH_SIBLINGS`, `BENCH_WARMUPS`, and `BENCH_TRIALS` override those defaults.
-// Reduced settings are useful only as a smoke test. Performance comparisons require
-// the same machine, filesystem, fixture sizes, settings, lockfile, and alternating
