vector: index-segment restriction + partition helper (P3 seam) (#12124)
* vector: allow restricting ANN search to index segments Query gains an optional index_segments list; when set and the index path is used, the scanner restricts the vector index search to those segments via with_index_segments. This is the seam the Enterprise planner uses to fan one query out across per-segment workers; OSS keeps passing None. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: enumerate and partition index segments for fanout segments::index_segments lists the physical segment UUIDs covering the vector field at the pinned version; partition() assigns them round-robin to workers. The parity test proves two workers scanning disjoint shares merge back to the full-dataset top-K — the P3 exit gate, in-process. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: let a query carry fragment ids for the unindexed sweep Lance only applies the index-segment restriction to indexed rows — unindexed fragments outside the selected segments are skipped. For a partitioned query to stay correct, the planner needs to hand the unindexed sweep to a worker too, so Query gains a fragments list that the scanner resolves to manifest fragments via with_fragments. A task carrying both searches its segments via the index and its fragments with flat KNN in the same scan. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: empty scope returns no hits; cover the sweep in tests Some([]) fragments or index_segments fell through to an unrestricted scan — a worker assigned nothing would have searched everything. empty_scope short-circuits those queries, and the segment restriction only calls with_index_segments on a non-empty list. segments::segment_fragments also returns each segment's live fragment bitmap, and the parity test now leaves a fragment unindexed so the worker carrying it exercises the flat sweep — the contract the Enterprise planner relies on. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: scope the scan to listed ∪ segment-covered fragments Lance intersects with_fragments with the selected index segments, so a worker given its segment share plus the unindexed sweep lost the share entirely — only the listed fragments were scanned. Expand the fragment list with the live coverage of the selected segments. The list is now also applied when it resolves empty: stale ids or an empty assignment must scan nothing, not fall through to an unrestricted scan. The merge test now leaves a fragment unindexed so the combined path is exercised.

vector: address remaining s3vectors review findings (#12115)
* vector: address remaining s3vectors review findings Catalog and permission model: - Vector buckets are declared Lance table buckets end to end: create sets format=lance, get/list/delete reject or skip ICEBERG buckets, and the format lookup runs on an internal trusted catalog so callers need no GetTableBucket grant. - The implicit "vector" index namespace is created through the same internal manager, so a CreateTable grant alone authorizes CreateIndex; typed S3TablesError codes replace string matching on err.Error(). - CreateIndex pre-checks existence after the authorize, tags the record with a create nonce, and rolls back on engine failure under context.WithoutCancel with a versionToken CAS, so a retry never deletes a table it did not create. - DeleteIndex drops the catalog record directly; DropIndex is unimplemented on the shared VectorService. - DeleteVectorBucket removes the empty internal namespace on BucketNotEmpty and retries once. - PutVectors/DeleteVectors require the update grant, and engine gRPC errors map to typed API errors instead of generic 500s. API correctness: - CreateVectorBucket/CreateIndex return their resource ARNs. - ARNs reject empty bucket segments; vectorBucketArn must be an ARN. - ListIndexes returns summaries built only from catalog fields. - ListVectors honors maxResults/nextToken inside a segment via "seg:<pageStart>:<nextIndex>" resume tokens and validates segmentCount/segmentIndex. - QueryVectors requires positive topK; PutVectors rejects empty keys. - CreateVectorBucket rejects a supplied encryptionConfiguration rather than silently dropping it. - Metadata filters emit Lance's real JSONB UDFs: json_get_string/ json_get_float/json_get_bool picked by operand type, json_exists with a bracketed JSONPath, and per-member accessors for $in/$nin. Engine: - weed-vector-server stores the metadata column as Lance JSONB (lance.json extension) so the json_* UDFs apply; reads accept legacy Utf8 JSON columns. Vectors port TLS: - The TLS config is built before binding listeners, loads -cacert.file into ClientCAs when client-cert verification is on, fails startup on an empty/invalid CA file, and closes the gRPC conn on every failure path. * s3vectors: authorize index create before writing the implicit namespace A denied caller could still leave a persistent namespace behind because ensureIndexNamespace wrote through the trusted catalog before the caller's create grant ran. AuthorizeCreateTable now tolerates the not-yet-declared implicit namespace (bucket policy alone decides) and runs before any write; real table creates keep requiring the namespace. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3vectors: keep engine error details out of the API response Unavailable now maps to 503 ServiceUnavailableException and unclassified codes return a generic message; the real gRPC error stays in the log. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3vectors: exact-type metadata filters + NULL-safe $nin The jsonb extractors convert numeric-looking strings through json_get_float and 'true'/'false' through json_get_bool, so a stored '3' could satisfy a filter for the number 3. Numeric and boolean comparisons now also require the stored value not be a string, and each $in/$nin group coalesces NULL so NOT cannot invert NULL into NULL.

Load it once up front.

When a token is supplied the name path now carries the observed mtime as an if_not_modified_after precondition (evaluated under the path lock), and a decoupled delete strips the catalog marker under a compare of the captured attributes before touching the data path. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3vectors: compare filter operands against the stored JSON type jsonb's strict converters make json_get_string return text for numbers and booleans too, so a get_string IS NULL guard is never true for scalar metadata — numeric and boolean comparisons silently matched nothing. Numbers and booleans now compare through TRY_CAST of the serialized json_extract text, which yields NULL on any other stored type; string comparisons stay on json_get_string behind a CASE guard so the extractor only runs on rows storing a JSON string.

Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3tables: assert the captured record before a conditional table delete An xattr update keeps Mtime, so the IfNotModifiedAfterNs guard alone could not see a metadata write that had already rotated the version token, and a recreate preserving the mtime could slip the mtime check. The delete now first proves the entry still carries the captured attributes under the filer's path lock, then keeps the mtime precondition. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3vectors: match only JSON boolean literals in metadata filters * filer,s3tables: delete versioned tables under one attribute precondition * s3vectors: compare serialized JSON for string filter operands json_get_string converts numeric-looking strings and booleans, so it cannot serve exact-typed string comparisons even behind a guard. String operands now compare the serialized json_extract text directly, which is exact-typed and never errors; a Rust test pins the semantics against a mixed-type dataset. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3vectors: compare boolean filter operands as serialized text Arrow's boolean cast accepts '1' and '0', so a TRY_CAST column let a stored number satisfy a boolean filter. Booleans now compare the serialized json_extract text like strings do — a JSON boolean only ever serializes as 'true' or 'false'. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3tables: claim a catalog name's markers in one compare-checked write A create wrote its markers attribute-by-attribute after checking the name was free. A delete's restore landing in the check-to-write gap put the old markers back first, and the create then overwrote only the ones it sets — leaving the old tags, policy, and maintenance settings on the new table. CreateTable, RegisterTable, and CreateView now write all their markers in a single update that refuses to run while any catalog marker is present, so the second writer loses with a conflict instead of inheriting them. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3tables: test the attribute-preconditioned table delete and name claim Adds a BeforeDelete hook plus ExpectedExtended evaluation to the in-memory filer so tests can land a competing write in a handler's check-to-delete window, and covers two losing races: a token delete whose record changed since the read, and a create colliding with a delete's marker restore. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3tables: reserve a catalog record under one compare-checked claim claimCatalogRecord writes a deleting marker onto the record while it still holds exactly the caller's captured attributes, so a delete or rename can hold the record through a multi-step operation and a losing writer backs out before any data or destination entry is written. The claim key joins the markers a name-claim asserts absent, so the name cannot be reused while the reservation stands. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3tables: claim the record before purging or publishing past it A token delete of a decoupled table purged the data first and checked the marker afterwards, so a rename that finished in between left the moved record pointing at purged data while the delete reported a conflict. The delete now claims the record under the captured attributes before any data is removed and releases the claim if the purge fails, keeping the record intact for a retry. The rename claims the source before publishing the destination, so a losing rename backs out while no destination entry exists instead of leaving one behind pointing at data a delete went on to remove.

vector: snapshot lease + maintenance safety tests (P2) (#12107)
* vector: version-lease helpers + maintenance safety tests Pinned queries must survive Lance maintenance. maintenance::pin tags the current dataset version so cleanup refuses to reclaim it; release drops the tag. Tests prove the P2 gate: a pinned query returns identical hits across compact_files, a tagged version survives cleanup_old_versions (error_if_tagged protects it, the non-strict run skips it), and a missing data file fails the query instead of returning partial hits. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: lease the query's dataset version in the VectorService query_vectors pins the resolved version with a query tag for the duration of the RPC and releases it after, so concurrent maintenance cleanup cannot reclaim the files out from under an in-flight read.

test/vectors: fix the S3 Vectors e2e harness (#12112)
* test/vectors: give the vector server static storage credentials The e2e harness ran weed-vector-server without credentials, so lance's AWS object store fell back to IMDS and CreateIndex died on the runner's 411 from the token endpoint. Point it at the test credentials the s3 gateway now reads from s3.json. * vector: take the list item field from the schema when batching vectors Lance stores the fixed-size list item as nullable even when the write schema declared it non-null, so PutVectors built batches that no longer matched: expected FixedSizeList(4 x Float32) but found FixedSizeList(4 x non-null Float32). * vector: store index metadata as lance jsonb so filters resolve The metadata field was plain Utf8, but the filter functions lance's planner registers (json_get_string, json_get_float, json_exists) take a LargeBinary jsonb column, so QueryVectors with a metadata filter failed to plan. Declare the field with the arrow.json extension — lance encodes it to jsonb on write and back on read — and encode the batch's strings when the stored column is LargeBinary. Also rename the filter's json_get_str call to json_get_string, the name lance registers. --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> |

Tests pin the behaviour the spike is for: rows appended after an index build stay in the top-K, and a version-pinned dataset never sees the next commit.

vector: seaweed-vector workspace + flat/indexed top-K engine (P0 phase 1) (#12096)
* vector: scaffold the seaweed-vector workspace Standalone cargo workspace for the vector query engine, mirroring the seaweed-worker layout: own lockfile, same lint policy, path dependencies across the two trees since there is no common root manifest. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: resolve a table's vector layout VectorTable::resolve finds the vector column (explicit name, else the column named vector, else the sole fixed-size float list), the optional key column, and the metadata columns a query can project. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: flat and indexed top-k, key lookup query::flat runs an exact scan (use_index(false)); query::ann lets Lance split the query between index segments and a flat pass over fragments no index covers yet, so rows written after the last index build stay eligible. Both honour a metadata filter and return the raw _distance in the query's metric. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: reject a non-utf8 or non-identifier key column An explicit --key-column naming a non-UTF8 field made hits() silently report row ids as keys, and get() interpolated the name into a SQL filter verbatim. Require Utf8 at resolve and in hits(), and require a plain identifier before building the IN predicate.

Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: quote the key column in the IN filter A Utf8 key column named e.g. document-key made the predicate parse as subtraction, and an identifier interpolated unquoted is injectable. Backtick-quote it and double its inner backticks; double quotes are string literals in the filter dialect, not identifiers. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * vector: project only the columns a hit needs The knn projection pulled every metadata column — including other vector columns — although Hit returns none of them. Filters still evaluate off the scan path, so restrict the output to the key and the scoring columns.
