test: update hash-split expectations for DataFusion 54 foldhash

DataFusion 54's `create_hashes` uses foldhash instead of ahash, so the concrete hash values (and therefore split assignments) differ from the DF53 baseline: - `test_hash_split` (Rust): recompute the expected per-split counts. - `test_split_hash_with_discard` (Python): hash a high-cardinality column instead of the 2-value `category`, so the discard ratio no longer hinges on where two specific hashes land.

chore: upgrade DataFusion to 54

+description: >-
+  Manage LanceDB table branches through the REST API: list, create, and delete
+  branches; target schema reads, field-metadata updates, and index creation to a
+  named branch; and verify that branch changes remain isolated from main. Use
+  when a task involves branch lifecycle, an experimental or isolated table
+  version, directing an operation to a non-main branch, or confirming that a
+  mutation did not affect main. This skill also explains that LanceDB has no
+  checkout operation; each request selects its target branch in the request
+  body.
+---
+
+## Goal
+
+Manage branches on a LanceDB table: list what exists, create new ones, delete stale ones, and direct read/write operations at a specific branch without touching main.
+
+## Step 0: Establish the connection
+
+Use the `lancedb-connect` skill to resolve the base URL and auth headers (`x-api-key`, `x-lancedb-database`). Skip this only if the connection is already known from the current conversation.
+
+All examples below use `{base_url}` — substitute the resolved endpoint and include the auth headers on every request.
+
+## The branch model (important)
+
+LanceDB branches are named snapshots that diverge from the table's current state at creation time. There is **no checkout command** — you never switch the whole table to a branch. Instead, you **pass `"branch": "<name>"` in the request body** of any operation to target that branch. Omitting the key (or sending an empty body) always targets main.
+
+`branches/list` returns only non-main branches. Main always exists and is not listed.
+
+## List branches
+
+```http
+POST {base_url}/v1/table/{table_id}/branches/list
+Content-Type: application/json
+
+{}
+```
+
+Response:
+```json
+{
+  "branches": {
+    "experiment-reindex": {"parentVersion": 1, "createAt": 1782506085, "manifestSize": 1029}
+  }
+}
+```
+
+If `branches` is `{}`, the table has no branches besides main.
+
+## Create a branch
+
+```http
+POST {base_url}/v1/table/{table_id}/branches/create
+Content-Type: application/json
+
+{"name": "experiment-reindex"}
+```
+
+HTTP 200 with `{}` body = success. The branch is created off the table's current state on main.
+
+Verify by calling `branches/list` and confirming the new name appears.
+
+## Delete a branch
+
+```http
+POST {base_url}/v1/table/{table_id}/branches/delete
+Content-Type: application/json
+
+{"name": "stale-2024"}
+```
+
+HTTP 200 with `{}` body = success. Only the branch pointer is removed — main and all row data remain intact.
+
+Verify by calling `branches/list` (name gone) and `describe` with no branch param (main still responds).
+
+## Operate on a specific branch
+
+Pass `"branch": "<name>"` in the body of any operation to scope it to that branch:
+
+**Read schema on a branch:**
+```http
+POST {base_url}/v1/table/{table_id}/describe
+Content-Type: application/json
+
+{"branch": "wip-branch"}
+```
+
+**Write metadata to a branch (not main):**
+```http

+Content-Type: application/json
+
+{
+  "branch": "wip-branch",
+  "updates": [
+    {
+      "path": "category",
+      "metadata": {"lancedb:description": "Product category label."},
+      "replace": false
+    }
+  ]
+}
+```
+
+**Build an index on a branch:**

+Content-Type: application/json
+
+{
+  "branch": "wip-branch",
+  "column": "category",
+  "index_type": "BTREE"
+}
+```
+
+## Verifying isolation
+
+After writing to a branch, always confirm the change did NOT land on main:
+
+```bash
+# Should show the new metadata
+curl -s -X POST {base_url}/v1/table/{table_id}/describe \
+  -H "x-api-key: <key>" -H "x-lancedb-database: <db>" \

+description: Column metadata authoring for LanceDB tables via the REST API. This skill is required for tasks like writing field descriptions, setting tags on columns (field_type, model, project_id, version), classifying columns as embeddings vs labels vs eval metrics, or grouping versioned columns into logical families — because it has the API integration needed to read the schema and persist metadata back. Invoke whenever someone wants to document, annotate, tag, or classify what their table columns ARE. Trigger even without an explicit "LanceDB" mention, as long as the context is column-level documentation or tagging for an ML or vector database table.
+metadata:
+  short-description: Write column descriptions, tags, and logical groupings to a LanceDB table
+---
+
+## Overview
+
+This skill authors column-level metadata for a LanceDB table. It connects to a LanceDB deployment over its REST API, inspects the table schema, generates appropriate metadata, and writes it back.
+
+## Step 0: Establish the connection
+
+Use the `lancedb-connect` skill (invoke it via the Skill tool) to resolve the base URL and auth headers (`x-api-key`, `x-lancedb-database`) for whichever deployment the user is working against — enterprise/self-hosted or a local dev server. Skip it only if the connection details are already established in the conversation.
+
+All examples below use `{base_url}` — substitute the resolved endpoint and include the resolved headers on every request.
+
+## Metadata keys
+
+All metadata uses namespaced keys:
+
+| Key | Purpose | Example value |
+|-----|---------|---------------|
+| `lancedb:description` | Human-readable explanation of what the column contains | `"CLIP ViT-L/14 image embedding, L2-normalized (768-dim)"` |
+| `lancedb:tag:<name>` | Flexible key-value tag; the suffix names the tag category | `lancedb:tag:field_type: "embedding"`, `lancedb:tag:model: "clip"`, `lancedb:tag:project_id: "foo"` |
+| `lancedb:logical-column` | Logical group/family this column belongs to | `"clip_features"` |
+
+Tags are open-ended — use whatever key suffix and value make sense given the user's intent. The tag suffix should describe *what is being classified* (e.g., `field_type`, `model`, `project_id`) and the value describes *how*.
+
+## Step 1: Resolve the table identifier
+
+You need:
+- **Table name** (required) — e.g., `my_table` or `my_namespace.my_table`
+- **Database name** — ask if not provided and not inferable from context; it goes in the `x-lancedb-database` header, never in the URL path
+
+The table identifier in the URL path is typically `table_name` for a top-level table, or `namespace$table_name` if the table lives in a namespace. The API accepts a `delimiter` query parameter to parse compound identifiers (default `$`).
+
+## Step 2: Describe the table
+
+```http
+POST {base_url}/v1/table/{table_id}/describe
+Content-Type: application/json
+
+{}
+```
+
+The response contains `schema.fields` — an array of field objects:
+
+```json
+{
+  "schema": {
+    "fields": [
+      {
+        "name": "clip_embedding_v3",
+        "type": { "type": "FixedSizeList", "fields": [...], "listSize": 768 },
+        "nullable": true,
+        "metadata": { "lancedb:description": "..." }
+      }
+    ]
+  }
+}
+```
+
+Each field has:
+- `name` — field name
+- `type` — Arrow data type (check `type.type` for the type string)
+- `nullable` — boolean
+- `metadata` — existing key-value metadata (read this before writing to avoid redundant updates)
+
+For struct/nested fields, recurse into `type.fields` and represent them as dot-notation paths (e.g., `parent.child`).
+
+If the user hasn't specified which columns to update, work with all columns.
+
+## Step 3: Generate metadata
+
+Decide what to generate based on the user's request.
+
+### Writing descriptions (`lancedb:description`)
+
+Base descriptions on:
+- The column name and Arrow type (e.g., `FixedSizeList` of floats → likely an embedding)
+- User-supplied context (upstream pipeline, sample values, domain knowledge)
+- Name patterns: `_embedding`/`_vec`/`_embed` → vector; `_label`/`_class` → label; `_score`/`_eval`/`_metric` → evaluation metric
+
+Be specific and concise. Good: `"Sentence-BERT embedding of the query text (768-dim)."` Not: `"An embedding column."`
+
+### Tagging columns (`lancedb:tag:<name>`)
+
+Choose tag key names that match what the user asked to annotate. Common patterns:
+
+- Semantic field type → `lancedb:tag:field_type: "embedding"` / `"text"` / `"image"` / `"label"` / `"eval"` / `"id"` / `"metadata"`
+- Model or source → `lancedb:tag:model: "clip"` / `"bert"` / `"vit"`
+- Project affiliation → `lancedb:tag:project_id: "<name>"`
+- Version → `lancedb:tag:version: "v3"` (and `lancedb:tag:latest: "true"` for the newest)
+
+Use Arrow type as a hint: `FixedSizeList` + float → embedding; `Utf8`/`LargeUtf8` → text; `Binary` → image or blob.
+
+Multiple tags on the same column are fine — each is a separate key.
+
+### Grouping into logical columns (`lancedb:logical-column`)
+
+Look for naming patterns across columns:
+- `clip_v1`, `clip_v2`, `clip_v3` → logical column `"clip"`, latest is `v3`
+- `text_embed_20240101`, `text_embed_20240601` → logical column `"text_embed"`, latest is the most recent date suffix
+
+Write `lancedb:logical-column` on all members of a group. Mark the newest with `lancedb:tag:latest: "true"` (in addition to its version tag).
+
+## Step 4: Write the metadata
+
+```http
+POST {base_url}/v1/table/{table_id}/update_field_metadata
+Content-Type: application/json
+
+{
+  "updates": [
+    {
+      "path": "clip_v3",
+      "metadata": {
+        "lancedb:description": "CLIP ViT-L/14 image embedding, L2-normalized (1024-dim).",
+        "lancedb:tag:field_type": "embedding",
+        "lancedb:tag:model": "clip",
+        "lancedb:tag:version": "v3",
+        "lancedb:tag:latest": "true",
+        "lancedb:logical-column": "clip"
+      },
+      "replace": false
+    },
+    {
+      "path": "clip_v2",
+      "metadata": {
+        "lancedb:description": "CLIP ViT-B/32 image embedding (768-dim), superseded by v3.",
+        "lancedb:tag:field_type": "embedding",
+        "lancedb:tag:model": "clip",
+        "lancedb:tag:version": "v2",
+        "lancedb:logical-column": "clip"
+      },
+      "replace": false
+    }
+  ]
+}
+```
+
+Rules:
+- **Use `"replace": false`** (merge) by default — this preserves existing metadata the user didn't ask to change
+- Use `"replace": true` only if the user explicitly asks to overwrite all existing metadata on a column
+- Set a value to `null` to delete a specific key
+- Batch all updates in a single request when possible
+
+The response includes `version` (new table version) and `fields` (the updated metadata per field).
+
+## Step 5: Confirm
+
+Report back:
+- Which columns were updated and what was written
+- The new table version number
+- Any columns skipped (e.g., already had up-to-date metadata)
+

+**"Tag the columns in `model_outputs` with their field type and model"**
+1. Describe `model_outputs`
+2. For each field, classify by name + Arrow type → set `lancedb:tag:field_type` and `lancedb:tag:model` where applicable
+3. POST `update_field_metadata`
+4. Report
+
+**"Group the feature columns in `training_features` into logical families and mark the latest version"**
+1. Describe the table
+2. Find version patterns → assign `lancedb:logical-column` and `lancedb:tag:version`; mark newest with `lancedb:tag:latest: "true"`
+3. POST `update_field_metadata`

+  short-description: Resolve the base URL and auth headers for a LanceDB deployment
+---
+
+## Goal
+
+Produce two things every REST request needs:
+
+1. **Base URL** — the endpoint
+2. **Headers** — `x-api-key`, and usually `x-lancedb-database`
+
+## Resolution steps
+
+1. If the user already gave a URL and API key (or said which environment they're working against), use that.
+2. Otherwise, look for credentials already available in the environment:
+   - Env vars like `LANCEDB_URI` / `LANCEDB_HOST` / `LANCEDB_API_KEY`
+   - A LanceDB endpoint already running or port-forwarded locally (the REST default port is 2333, i.e. `http://localhost:2333`)
+3. If you didn't find both pieces, ask the user directly: **"What's your LanceDB endpoint's URL, and what's your API key?"** Also ask which database to use if it isn't obvious. Don't guess or probe further — the user knows their deployment.
+
+## Validating the connection
+
+Make a cheap authenticated request and check the status:
+
+```bash
+curl -s -w "\n%{http_code}" "{base_url}/v1/table/?limit=1" \
+  -H "x-api-key: <key>" \
+  -H "x-lancedb-database: <database>"
+```
+
+- `200` — connection, key, and database header all good
+- `401` — API key missing or wrong
+- `400` mentioning a database header — this deployment expects `x-lancedb-database`
+
+## Non-REST equivalents
+
+If the caller would rather use the SDK or CLI than raw REST, the same credentials work:
+
+- Python SDK: `lancedb.connect("db://<database>", api_key="<key>", host_override="<base_url>")`
+- `lancedb` CLI: a `[profiles.<name>]` entry in `~/.lancedb/config.toml` with `http_server_url`, `api_key`, `database`

-Merges by default; a `null` value deletes that key; `replace: true` swaps the whole map. Nested fields use dot-paths (`"a.b.c"`). See `references/column_metadata.md` for key conventions (`lancedb:description`, `lancedb:tag:<name>`, `lancedb:logical-column`) and the authoring workflow.

-## Branches
-
-```typescript
-const branches = await table.branches();       // async manager
-await branches.list();                         // non-main branches; {} = only main
-const exp = await branches.create("exp");      // fork off main -> Table scoped to the branch
-const wip = await branches.checkout("wip");    // existing branch -> scoped Table (version arg pins read-only)
-const wip2 = await db.openTable("t", { branch: "wip" }); // or open scoped directly
-await branches.delete("stale");                // removes only the branch pointer
-table.currentBranch();                         // null = main
-```
-
-There is no global switch — scoping is per table handle: any read/write on a branch handle lands on that branch; the original handle keeps targeting main. See `references/branch_ops.md` for the model and isolation checks.

-    The current Java namespace API exposes index type, index name, distance type, and full text search tokenizer options.

-# Branch Operations
-
-Manage branches on a LanceDB table: list what exists, create new ones, delete stale ones, and direct read/write operations at a specific branch without touching main. Use for branch lifecycle tasks, experimental/isolated table versions, targeting an operation at a non-main branch, or confirming a mutation did not affect main.
-
-Works on local/OSS and remote Enterprise/Cloud tables, except merging a branch into main, which is Enterprise-only.
-
-## The branch model (important)
-
-Branches are isolated, writable lines of history forked from another branch (or a specific version). Writes on a branch never affect `main`.
-
-There is **no global "switch branch" state** — you never repoint the whole table at a branch. Instead, **operations are scoped by which table handle you use**:
-
- The handle you got from `open_table(name)` / `openTable(name)` targets `main`.
- `branches.create(...)` and `branches.checkout(...)` return a **new table handle scoped to that branch**. Every read/write on that handle (add, update, `update_field_metadata`, `create_index`, search, …) lands on the branch.
- The original main handle is unaffected — keep it around to verify isolation.
-
-`branches.list()` returns only non-main branches. Main always exists and is not listed.
-
-## Python
-
-`table.branches` is a property returning the branch manager; `table.current_branch()` tells you what a handle is scoped to (`None` = main).
-
-```python
-table = db.open_table("products")            # scoped to main
-
-# list — dict of name -> metadata (parent_branch, parent_version, ...); {} = only main
-table.branches.list()
-
-# create: forks from main by default and returns a handle scoped to the new branch
-exp = table.branches.create("experiment-reindex")
-exp = table.branches.create("exp2", from_ref="main", from_version=None)  # optional fork point
-
-# checkout an existing branch -> branch-scoped handle
-wip = table.branches.checkout("wip-branch")
-# with version= it pins to that version (read-only detached view); omit to track latest, writable
-
-# operate on the branch simply by using its handle
-wip.update_field_metadata(
-    {"path": "category", "metadata": {"lancedb:description": "Product category label."}}
-)
-wip.create_scalar_index("category")
-
-# delete: removes only the branch pointer; main and row data remain intact
-table.branches.delete("stale-2024")
-
-# alternatively, open a branch handle directly from the connection
-wip = db.open_table("products", branch="wip-branch")
-
-exp.current_branch()    # "experiment-reindex"
-table.current_branch()  # None (main)
-```
-
-Async: same shape — `table.branches` returns `AsyncBranches`; `await table.branches.create(...)` etc.
-
-## TypeScript
-
-`table.branches()` is an **async method** returning the `Branches` manager; `table.currentBranch()` returns the scoped branch or `null` for main.
-
-```typescript
-const table = await db.openTable("products"); // scoped to main
-const branches = await table.branches();
-
-// list — Record<string, BranchContents>; {} = only main
-await branches.list();
-
-// create: forks from main by default, returns a Table scoped to the new branch
-const exp = await branches.create("experiment-reindex");
-const exp2 = await branches.create("exp2", "main" /* fromRef */, undefined /* fromVersion */);
-
-// checkout an existing branch -> branch-scoped Table
-const wip = await branches.checkout("wip-branch");
-// with a version arg it pins (read-only detached view); omit to track latest, writable
-
-// operate on the branch simply by using its handle
-await wip.updateFieldMetadata([
-  { path: "category", metadata: { "lancedb:description": "Product category label." } },
-]);
-await wip.createIndex("category");
-
-// delete: removes only the branch pointer; main and row data remain intact
-await branches.delete("stale-2024");
-
-// alternatively, open a branch handle directly from the connection
-const wip2 = await db.openTable("products", { branch: "wip-branch" });
-
-exp.currentBranch();   // "experiment-reindex"
-table.currentBranch(); // null (main)
-```
-
-## Verifying isolation
-
-After writing to a branch, confirm the change did NOT land on main by reading through both handles:
-
-```python
-wip = table.branches.checkout("wip-branch")
-wip.update_field_metadata({"path": "category", "metadata": {"lancedb:description": "..."}})
-
-assert b"lancedb:description" in (wip.schema.field("category").metadata or {})
-assert b"lancedb:description" not in (table.schema.field("category").metadata or {})  # main untouched
-```
-
-Two handles on the same branch see each other's writes (e.g. `table.branches.create("exp")` and `db.open_table(name, branch="exp")`); main stays isolated.
-
-## Merging a branch into main (Enterprise only)
-
-Merge is available through the SDKs (`table.branches.merge(...)`) on **Enterprise tables only** — it is not supported on Cloud or local/OSS tables, which raise `NotSupported`.
-
-`merge` takes the branch to merge **from** and a `dry_run` flag. Both the SDK method and the underlying REST endpoint **actually merge by default** (`dry_run=False`); pass `dry_run=True` to only preview. A rejected merge is **not an exception** — it returns a result with `status="rejected"` rather than raising, so inspect the return value. Use `branches.diff(from_branch)` to inspect a branch's pending diff without attempting a merge.
-
-```python
-exp = "experiment-reindex"
-
-# preview only — returns status="ready" if it would merge cleanly
-preview = table.branches.merge(exp, dry_run=True)
-
-# actually merge (default)
-result = table.branches.merge(exp)
-if result["status"] == "merged":
-    print("landed at", result["mainVersionAfter"])
-elif result["status"] == "rejected":
-    print(result["diff"]["mergeBlockers"])   # why it was refused
-
-# inspect a branch's pending diff without merging
-diff = table.branches.diff(exp)
-```
-
-Async: `await table.branches.merge(exp)`, `await table.branches.diff(exp)`.
-
-```typescript
-const branches = await table.branches();
-const exp = "experiment-reindex";
-
-// preview only (second arg is dryRun)
-const preview = await branches.merge(exp, true);
-
-// actually merge (default)
-const result = await branches.merge(exp);
-if (result.status === "merged") {
-  console.log("landed at", result.mainVersionAfter);
-} else if (result.status === "rejected") {
-  console.log(result.diff.mergeBlockers);
-}
-
-const diff = await branches.diff(exp);
-```
-
-The result is the wire JSON, containing `status` (`ready` on a passing dry run, `merged` on success, `rejected` when refused — also `notImplemented`/`unknown`), the branch `diff` (including `mergeBlockers` explaining any rejection), a `preview` of the columns that would be promoted, and — after a real merge — `mainVersionAfter`.
-
-### Merge preconditions
-
-Merge only **promotes newly added columns** onto main; it does not replay arbitrary commits. Practically, a branch is mergeable only if it has **exactly one commit since it was created, and that commit added a column**. The merge is rejected (`status: "rejected"`, with `mergeBlockers` set) if:
-
- the branch was forked from another branch rather than directly from main
- main has advanced since the branch was forked
- the branch's rows changed since the fork (row counts must match main exactly)
- the branch removed columns or changed a column's type/nullability
- the branch added no columns (index-only changes are not merged)
-
-### Adding a column in a single commit
-
-Because the branch must contain just one column-adding commit, add the column with its values in one operation rather than add-then-backfill:
-
-1. **SQL transformation** — `add_columns` with a SQL expression computed from existing columns, so the column lands populated in one commit.
-2. **Precompute the values** — compute the column's values externally, then add the fully-populated column in a single operation (e.g. via `merge_insert`/`add_columns` with the data ready).
-3. **Lance-format-level data evolution (pylance)** — use Lance's data evolution with backfill, documented at <https://lance.org/guide/data_evolution/#with-data-backfill>.

-# Column Metadata Authoring
-
-Write column-level descriptions, tags, and logical groupings onto a LanceDB table's schema. Use this when the user wants to document, annotate, tag, or classify what their table columns ARE (embeddings vs labels vs eval metrics, model provenance, version families, etc.).
-
-Works on local/OSS and remote Enterprise/Cloud tables alike — read the schema through the table handle, write through `update_field_metadata` (Python) / `updateFieldMetadata` (TypeScript).
-
-## Metadata key conventions
-
-All metadata uses namespaced keys:
-
-| Key | Purpose | Example value |
-|-----|---------|---------------|
-| `lancedb:description` | Human-readable explanation of what the column contains | `"CLIP ViT-L/14 image embedding, L2-normalized (768-dim)"` |
-| `lancedb:tag:<name>` | Flexible key-value tag; the suffix names the tag category | `lancedb:tag:field_type: "embedding"`, `lancedb:tag:model: "clip"`, `lancedb:tag:project_id: "foo"` |
-| `lancedb:logical-column` | Logical group/family this column belongs to | `"clip_features"` |
-
-Tags are open-ended — use whatever key suffix and value make sense given the user's intent. The tag suffix should describe *what is being classified* (e.g., `field_type`, `model`, `project_id`) and the value describes *how*. Multiple tags on the same column are fine — each is a separate key. All values are strings.
-
-## Step 1: Read the schema and existing metadata
-
-Read existing metadata before writing, to avoid redundant updates.
-
-Python — `table.schema` (sync property; async: `await table.schema()`) returns a `pyarrow.Schema`. **Arrow field metadata is bytes-keyed in Python**:
-
-```python
-schema = table.schema
-for field in schema:
-    meta = field.metadata or {}  # dict[bytes, bytes], e.g. {b"lancedb:description": b"..."}
-    print(field.name, field.type, field.nullable, meta)
-```
-
-TypeScript — `await table.schema()` returns an Arrow `Schema`; field metadata is a `Map<string, string>`:
-
-```typescript
-const schema = await table.schema();
-for (const field of schema.fields) {
-  console.log(field.name, field.type, field.nullable, field.metadata); // Map
-  // field.metadata.get("lancedb:description")
-}
-```
-
-For struct/nested fields, recurse into the field's children and address them as dot-paths (e.g., `parent.child`).
-
-If the user hasn't specified which columns to update, work with all columns.
-
-## Step 2: Generate metadata
-
-Decide what to generate based on the user's request.
-
-### Descriptions (`lancedb:description`)
-
-Base descriptions on:
- The column name and Arrow type (e.g., `FixedSizeList` of floats → likely an embedding)
- User-supplied context (upstream pipeline, sample values, domain knowledge)
- Name patterns: `_embedding`/`_vec`/`_embed` → vector; `_label`/`_class` → label; `_score`/`_eval`/`_metric` → evaluation metric
-
-Be specific and concise. Good: `"Sentence-BERT embedding of the query text (768-dim)."` Not: `"An embedding column."`
-
-### Tags (`lancedb:tag:<name>`)
-
-Choose tag key names that match what the user asked to annotate. Common patterns:
-
- Semantic field type → `lancedb:tag:field_type: "embedding"` / `"text"` / `"image"` / `"label"` / `"eval"` / `"id"` / `"metadata"`
- Model or source → `lancedb:tag:model: "clip"` / `"bert"` / `"vit"`
- Project affiliation → `lancedb:tag:project_id: "<name>"`
- Version → `lancedb:tag:version: "v3"` (and `lancedb:tag:latest: "true"` for the newest)
-
-Use Arrow type as a hint: `FixedSizeList` + float → embedding; `Utf8`/`LargeUtf8` → text; `Binary` → image or blob.
-
-### Logical groupings (`lancedb:logical-column`)
-
-Look for naming patterns across columns:
- `clip_v1`, `clip_v2`, `clip_v3` → logical column `"clip"`, latest is `v3`
- `text_embed_20240101`, `text_embed_20240601` → logical column `"text_embed"`, latest is the most recent date suffix
-
-Write `lancedb:logical-column` on all members of a group. Mark the newest with `lancedb:tag:latest: "true"` (in addition to its version tag).
-
-## Step 3: Write the metadata
-
-Each update names a field by dot-path and carries a metadata map. Semantics (identical in both SDKs):
-
- **Merge by default** (`replace` omitted/false) — preserves existing metadata the user didn't ask to change
- `replace: true` swaps the field's entire metadata map — only if the user explicitly asks to overwrite
- A value of `None`/`null` deletes that specific key
- Batch all field updates into a single call when possible
- Returns the new table version
-
-Python (sync and async take one dict per field, as varargs):
-
-```python
-res = table.update_field_metadata(
-    {
-        "path": "clip_v3",
-        "metadata": {
-            "lancedb:description": "CLIP ViT-L/14 image embedding, L2-normalized (1024-dim).",
-            "lancedb:tag:field_type": "embedding",
-            "lancedb:tag:model": "clip",
-            "lancedb:tag:version": "v3",
-            "lancedb:tag:latest": "true",
-            "lancedb:logical-column": "clip",
-        },
-    },
-    {
-        "path": "clip_v2",
-        "metadata": {
-            "lancedb:description": "CLIP ViT-B/32 image embedding (768-dim), superseded by v3.",
-            "lancedb:tag:field_type": "embedding",
-            "lancedb:tag:model": "clip",
-            "lancedb:tag:version": "v2",
-            "lancedb:logical-column": "clip",
-        },
-    },
-)
-print(res.version)  # new table version
-
-# merge semantics: add a key, delete one via None, keep the rest
-table.update_field_metadata(
-    {"path": "clip_v2", "metadata": {"lancedb:tag:archived": "true", "lancedb:tag:latest": None}}
-)
-```
-
-(`replace_field_metadata` is deprecated — use `update_field_metadata`.)
-
-TypeScript (takes an array of `FieldMetadataUpdate`):
-
-```typescript
-const res = await table.updateFieldMetadata([
-  {
-    path: "clip_v3",
-    metadata: {
-      "lancedb:description": "CLIP ViT-L/14 image embedding, L2-normalized (1024-dim).",
-      "lancedb:tag:field_type": "embedding",
-      "lancedb:tag:model": "clip",
-      "lancedb:tag:version": "v3",
-      "lancedb:tag:latest": "true",
-      "lancedb:logical-column": "clip",
-    },
-  },
-  {
-    path: "clip_v2",
-    metadata: {
-      "lancedb:description": "CLIP ViT-B/32 image embedding (768-dim), superseded by v3.",
-      "lancedb:tag:field_type": "embedding",
-      "lancedb:tag:model": "clip",
-      "lancedb:tag:version": "v2",
-      "lancedb:logical-column": "clip",
-    },
-  },
-]);
-console.log(res.version); // new table version
-
-// merge semantics: add a key, delete one via null, keep the rest
-await table.updateFieldMetadata([
-  { path: "clip_v2", metadata: { "lancedb:tag:archived": "true", "lancedb:tag:latest": null } },
-]);
-```
-
-## Step 4: Confirm
-
-Report back:
- Which columns were updated and what was written
- The new table version number (from the result)
- Any columns skipped (e.g., already had up-to-date metadata)
-
-## Quick examples
-
-**"Write descriptions for all columns in the `product_embeddings` table"**
-1. Read `table.schema` → all fields + existing metadata
-2. Generate a `lancedb:description` for each column based on name + type
-3. One `update_field_metadata` call with all descriptions
-4. Report
-
-**"Tag the columns in `model_outputs` with their field type and model"**
-1. Read the schema
-2. For each field, classify by name + Arrow type → set `lancedb:tag:field_type` and `lancedb:tag:model` where applicable
-3. Write in one batched call
-4. Report
-
-**"Group the feature columns in `training_features` into logical families and mark the latest version"**
-1. Read the schema
-2. Find version patterns → assign `lancedb:logical-column` and `lancedb:tag:version`; mark newest with `lancedb:tag:latest: "true"`
-3. Write in one batched call
-4. Show the grouping

-# Connecting to a LanceDB remote server
-
-LanceDB Enterprise/Cloud deployments are served by a server implementing the
-lance-namespace OpenAPI spec
-(<https://github.com/lance-format/lance-namespace/blob/main/docs/src/spec.yaml>).
-Every remote (`db://...`) connection talks to such a server, and some operations
-exist only there. In particular, all operations around jobs (listing, inspecting,
-creating, or canceling jobs) run server-side — there is no local/OSS equivalent, so
-resolve a server connection before attempting any job work. The job REST methods
-themselves are documented in `references/remote_jobs.md`.
-
-Every request needs two things:
-
-1. **Base URL** — the server endpoint
-2. **Credentials** — an API key (`x-api-key` header over REST), and usually a database name (`x-lancedb-database` header)
-
-## Resolution steps
-
-1. If the user already gave a URL and API key (or said which environment they're working against), use that.
-2. Otherwise, look for credentials already available in the environment:
-   - Env vars like `LANCEDB_URI` / `LANCEDB_HOST` / `LANCEDB_API_KEY`
-   - A server endpoint already running or port-forwarded locally (the REST default port is 2333, i.e. `http://localhost:2333`)
-3. If you didn't find both pieces, ask the user directly: **"What's your LanceDB endpoint's URL, and what's your API key?"** Also ask which database to use if it isn't obvious. Don't guess or probe further — the user knows their deployment.
-
-## Validating the connection
-
-Make a cheap authenticated request and check the status before starting real work:
-
-```bash
-curl -s -w "\n%{http_code}" "{base_url}/v1/table/?limit=1" \
-  -H "x-api-key: <key>" \
-  -H "x-lancedb-database: <database>"
-```
-
- `200` — connection, key, and database header all good
- `401` — API key missing or wrong
- `400` mentioning a database header — this deployment expects `x-lancedb-database`
-
-## Non-REST equivalents
-
-The same credentials work through the SDKs and CLI:
-
- Python SDK: `lancedb.connect("db://<database>", api_key="<key>", host_override="<base_url>")`
- TypeScript SDK: `await lancedb.connect("db://<database>", { apiKey: "<key>", hostOverride: "<base_url>" })`
- `lancedb` CLI: a `[profiles.<name>]` entry in `~/.lancedb/config.toml` with `http_server_url`, `api_key`, `database`

-# Job operations over the LanceDB remote server REST API
-
-Jobs are server-side background operations on LanceDB Enterprise/Cloud — index builds,
-column backfills, materialized view refreshes, and similar async work. Endpoints that
-trigger async work (e.g. the column backfill or materialized view refresh endpoints)
-return a `job_id`; these four methods are how you track and manage those jobs.
-
-Resolve the connection first — see `references/remote_connect.md`. All four methods
-are **POST** requests under `{base_url}/v1/jobs/` with JSON bodies, and take the usual
-`x-api-key` / `x-lancedb-database` headers. If every job call returns `501`, job APIs
-are disabled on that deployment (the server has no job registry configured) — report
-that rather than retrying.
-
-## 1. List jobs — `POST /v1/jobs/list`
-
-The body is optional; an empty body lists everything. All fields are filters:
-
-```json
-{
-  "limit": 100,
-  "table_name": "my_table",
-  "job_type": "...",
-  "job_subtype": "...",
-  "state": "...",
-  "page_token": "..."
-}
-```

-  -H "content-type: application/json" \
-  -d '{"table_name": "my_table"}'
-```
-
-Response:
-
-```json
-{
-  "jobs": [
-    {
-      "job_id": "...",
-      "table": "my_table",
-      "job_type": "...",
-      "job_subtype": "...",
-      "state": "done",
-      "created_at_millis": 1720000000000
-    }
-  ],
-  "page_token": "..."
-}
-```
-
-A `page_token` in the response means there are more results — pass it back in the next
-request to continue. Note list rows use a lowercase `state` string, while describe uses
-an uppercase `job_state`.
-
-## 2. Describe a job — `POST /v1/jobs/describe`
-
-Body: `{"job_id": "<id>"}`. Returns full detail for one job:
-
-```json
-{
-  "job_id": "...",
-  "job_type": "...",
-  "job_subtype": "...",
-  "job_state": "IN_PROGRESS",
-  "creation_ms": 1720000000000,
-  "spec": {},
-  "status": {}
-}
-```
-
-`job_state` is one of `IN_PROGRESS`, `CANCELLED`, `FAILED`, `DONE`. `spec` and `status`
-are job-type-specific JSON objects (the job's input specification and its current
-progress/status). Returns `404` for an unknown job id.
-
-## 3. Cancel a job — `POST /v1/jobs/cancel`
-
-Body: `{"job_id": "<id>"}`; response echoes `{"job_id": "<id>"}`. Cancellation is a
-service-level operation requiring the same administrative authorization as the
-`/admin` routes — a database-scoped API key that can list and describe jobs may still
-get a permission error here. Other errors: `404` unknown job, `409` state conflict
-(e.g. already in a terminal state), `429` too much write contention (safe to retry).
-
-## 4. Query job event history — `POST /v1/jobs/query_events`
-
-Returns the event history (state transitions, progress updates) for one or more jobs.
-Body: `{"job_id": "<id>"}` for one job, or `{"job_ids": ["<id>", ...]}` for a batch.
-Optional fields: `limit` (max event rows), `limit_per_job` (per job in a batch query),
-and `filter` — a SQL-like expression over the columns `state`, `updated_by`,
-`owner_component`, and `claim_entity`. (`full_text_search` is reserved and currently
-rejected as not implemented.)
-
-The response is **not JSON** — it is an Arrow IPC stream
-(`content-type: application/vnd.apache.arrow.stream`). Decode it, e.g. in Python:
-
-```python
-import pyarrow.ipc
-import requests
-

-## Feature engineering (Geneva) jobs
-
-Feature engineering jobs — UDF column backfills and materialized view refreshes run
-through Geneva — are tracked **separately** from the `/v1/jobs` registry above. Their
-records live in a `geneva_jobs` table inside the database itself (in the `__system`
-namespace), and you access them through a Python `geneva` connection rather than the
-REST endpoints above:
-
-```python
-import geneva
-from geneva.jobs import JobStateManager
-
-# Same credentials as lancedb.connect / the REST API
-conn = geneva.connect("db://<database>", api_key="<key>", host_override="<base_url>")
-jsm = JobStateManager(conn)
-
-# List jobs. NOTE: status defaults to "RUNNING"; pass status=None for all jobs.
-# Statuses: PENDING | RUNNING | DONE | FAILED | CANCELLED
-jobs = jsm.list_jobs(table_name="my_table", status=None)
-
-# Fetch one job by id (returns a list of JobRecord)
-records = jsm.get("<job_id>")
-```
-
-Each `JobRecord` has `table_name`, `column_name`, `job_id`, `job_type`, `status`,
-`launched_at`, `completed_at`, `config`, `launched_by`, `manifest_id`, `cluster_name`,
-`metrics` (progress counters), `events` (human-readable history), and `updated_at`.
-For filters `list_jobs` doesn't support (e.g. time ranges), query the underlying table
-directly: `jsm.get_table(True).search().where("launched_at >= TIMESTAMP '...'")` —
-pass `True` to check out the latest version, since other processes update job state.
-
-Stale-status caveat: nothing reaps dead Geneva jobs, so a job can sit in
-`RUNNING`/`PENDING` forever if its worker died. Treat a job as effectively `FAILED`
-when it has been running longer than ~36 hours, or its `updated_at` is more than ~2
-hours old (this matches the heuristic the Geneva console UI applies on read).
-
-## Workflow tips
-
- To wait for async work (a backfill, an index build), poll `describe` until
-  `job_state` leaves `IN_PROGRESS`; on `FAILED`, pull `status` and `query_events` for
-  the failure detail.

-### Pre-Haswell x86_64 hosts: `lancedb-compat`
-
-The default `lancedb` wheel targets `x86-64-haswell` (AVX2 + FMA + F16C) for full performance on modern hardware. Pre-Haswell hosts — Intel Sandy Bridge / Ivy Bridge / Westmere; AMD Bulldozer / Piledriver / Steamroller — don't have AVX2 and crash with `Illegal instruction` at `import lancedb`.
-
-For those hosts, install the `lancedb-compat` package instead:
-
-```bash
-pip install lancedb-compat
-```
-
-Same Python API (`import lancedb` works as usual). The compat wheel is compiled at the `x86-64-v2` baseline (Nehalem-class) and uses runtime SIMD dispatch in the embedded lance crate to pick the right kernel tier (scalar / AVX / AVX+FMA / AVX2+FMA / AVX-512) at load time, so it still goes fast on modern hardware while running cleanly on the pre-Haswell silicon. Use `lance.simd_info()` from Python to verify which tier was selected.
-
-`lancedb` and `lancedb-compat` install to the same `lancedb/` namespace and conflict at install time. Pick one. To switch, `pip uninstall lancedb` first, then `pip install lancedb-compat` (or vice-versa).
-
-If you need a custom baseline (or `lancedb-compat` isn't yet published for your platform), build from source with the override:
-
-```bash
-RUSTFLAGS="-C target-cpu=x86-64-v2" maturin build --release
-pip install ./target/wheels/lancedb-*.whl
-```

 ### Preview Releases

 Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.
