fix(engine): close the 2 Lance 7.0.0 alignment failures (immutable PK + native namespace) (#236)
* fix(engine): make the v1→v2 manifest migration idempotent under Lance 7's immutable unenforced primary key Lance 7 (dataset/transaction.rs) makes the unenforced primary key immutable once set: any write touching the reserved `lance-schema:unenforced-primary-key` field metadata after the PK is set errors "cannot be changed once set" — even re-applying the same value. `migrate_v1_to_v2` previously relied on the old Lance 6 idempotency (re-applying the annotation was a no-op-ish bump), which it needs for crash-recovery: a v1 graph that crashes after the field-set but before the stamp bump re-enters the migration with the PK already present. Under Lance 7 that re-entry now errors, so a real pre-v0.4.0 graph crashing in that window could never complete its migration. Guard the field-set with `schema().unenforced_primary_key().is_empty()` so a genuine first-set still runs but a re-set is skipped — restoring crash-idempotency by construction. (Fresh graphs bake the PK into manifest_schema() at init and never run this migration.) The existing test_publish_migrates_pre_stamp_manifest_to_current_version is the regression guard: red under Lance 7 before this change, green after. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(engine): realign the native-namespace surface guard to Lance 7 (TableNotFound) `test_directory_namespace_direct_publish_cannot_replace_native_omnigraph_write_path` pokes Lance's NATIVE DirectoryNamespace (not omnigraph's production write path, which is the manifest merge_insert publisher) to document that it cannot replace omnigraph's authority. Lance 7's DirectoryNamespace routes list/describe/create_table_version through `check_table_status`, which now reports an omnigraph-manifest-tracked table as absent — so all three return TableNotFound for `node:Person` (observed). The native namespace is now fully decoupled from omnigraph's manifest: it cannot enumerate, inspect, or publish over omnigraph's tables. This strengthens the guard's thesis. Realigned the assertions to the v7 behavior and kept the authority check (omnigraph's refresh ignores the direct append; row_count stays 0). Test-only; no production impact. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(lance): document the 2 runtime behavior changes in the 7.0.0 alignment stanza The #229 stanza verified a clean engine *build* but not the test suite, and claimed "no Lance API surface omnigraph uses changed." Two runtime behaviors did, caught only by the full test suite: - the unenforced primary key is immutable once set in v7 (transaction.rs) — broke the v1→v2 manifest migration's crash-idempotency; fixed by an is-set guard; - the native DirectoryNamespace returns TableNotFound for omnigraph manifest-tracked tables (dir.rs) — test-only; the surface guard was realigned. Corrects the over-broad "no surface changed" claim, adds both findings, and notes the lesson: a clean build is not a clean alignment — run cargo test --workspace before declaring a Lance bump done.

build(deps): bump Lance 6.0.1 → 7.0.0 (correct-by-design substrate alignment) (#229)
* build(deps): bump Lance 6.0.1 → 7.0.0 (object_store 0.13.2, roaring 0.11.4) Arrow stays 58 and DataFusion stays 53 (no change). The only transitive bump is object_store 0.12.5 → 0.13.2. 141 upstream commits reviewed; no fixes lost (the 6.0.x release-branch backports are all forward-ported into 7.0.0). - object_store 0.13 moved get/put/head/rename/delete behind a new ObjectStoreExt trait (list/list_with_delimiter/put_opts stay on the core trait). Add `use object_store::ObjectStoreExt` in storage.rs and db/manifest/namespace.rs; no call-site changes. Mirrors Lance's own migration in PR #6672. - roaring pinned to 0.11.4 (cargo update -p roaring --precise 0.11.4). Lance 7.0.0's UpdatedFragmentOffsets newtype (lance#6650) derives Eq over HashMap<u64, RoaringBitmap>, which needs RoaringBitmap: Eq, added in roaring 0.11.4; the loose `roaring = "0.11"` constraint otherwise resolves 0.11.3 and lance itself fails to compile. - lance#6774: merge-insert INSERT rows now stamp _row_created_at_version with the commit version (was a fallback of 1). Flip the lance_version_columns assertion to `== v2` and correct the changes/mod.rs rationale comment. Production change-detection keys on _row_last_updated_at_version + ID membership, so its logic is unaffected. Refs lance#6650, lance#6774, lance#6672. * fix(storage): pin WriteParams::auto_cleanup = None (lance#6755 default flip) lance#6755 flipped the WriteParams::auto_cleanup default from on (a full cleanup pass every 20th commit) to None. On 6.0.1 the on-by-default hook could silently GC versions that __manifest pins for snapshots/time-travel. OmniGraph owns cleanup explicitly (optimize.rs::cleanup_all_tables) and never set auto_cleanup, so it was relying on a default that is both wrong for our snapshot model and now changed upstream. Pin auto_cleanup: None explicitly at all 11 production WriteParams sites (table_store ×6, commit_graph ×2, recovery_audit ×1, manifest/graph ×2 — the __manifest + sub-table Create paths). Removes the dependency on a default-flag value and locks in the snapshot-safe behavior regardless of future upstream re-flips. Refs lance#6755. * test(lance): pin BTREE range-boundary correctness (lance#6796) lance#6796 (issue #6792) fixed a BTREE scalar-index range-query bound inclusiveness bug: `x <= hi AND x > lo` returned the wrong boundary row. Add lance_surface_guards.rs::btree_range_query_boundary_is_correct, which reproduces the exact #6792 shape (5 rows + an explicit BTREE drives the index path even on tiny data) and pins the corrected inclusive-<= / exclusive-> semantics. It turns red if a future Lance regression reintroduces the bug. OmniGraph today builds BTREE only on string @key columns and queries them by equality/IN, so its current patterns do not hit this; the guard protects any future BTREE-range path (BTREE-on-properties, range-on-key). Refs lance#6796. * docs(dev): align Lance docs + invariants to 7.0.0 - docs/dev/lance.md: new 2026-06-14 alignment stanza for the 6.0.1 → 7.0.0 bump (object_store ObjectStoreExt move, roaring 0.11.4, #6774/#6796/#6755 behavior, #6658 shipped → MR-A unblocked but separate, #6666 + blob compaction still open); prior 6.0.1 stanza demoted to historical. - AGENTS.md: storage substrate 6.x → 7.x (line + architecture diagram). - docs/dev/invariants.md: deletes/vector known gap updated — the staged two-phase delete API (lance#6658) now exists and MR-A is unblocked, but delete_where stays inline and D2 stays in place until the migration lands; create_vector_index still gated on lance#6666. * fix(storage): skip Lance auto-cleanup on commit paths for legacy datasets Addresses PR #229 review (Codex P1). `WriteParams::auto_cleanup` is create-time config with no effect on existing datasets (Lance write.rs docs), so the previous `auto_cleanup: None` change alone did NOT protect graphs created before the v7 bump: 6.0.1 defaulted auto_cleanup ON, leaving `lance.auto_cleanup.*` config on those datasets, and Lance's per-commit hook (io/commit.rs: `if !commit_config.skip_auto_cleanup`) fires off that stored config — so omnigraph's own writes would GC versions the __manifest pins for snapshots/time-travel. Skip the hook on every commit path, covering new and legacy datasets alike: - commit_staged: CommitBuilder::with_skip_auto_cleanup(true) — the staged data path. - __manifest publisher: MergeInsertBuilder::skip_auto_cleanup(true). - all 11 WriteParams: skip_auto_cleanup: true (direct Dataset::write/append paths; auto_cleanup: None retained so new datasets store no cleanup config at all). Tests: - lance_surface_guards::skip_auto_cleanup_suppresses_version_gc — substrate: negative control (config GCs v1 without skip) + with-skip survival. - staged_writes::commit_staged_skips_auto_cleanup_so_pinned_versions_survive — omnigraph usage: commit_staged on a legacy-config dataset preserves the pinned create version. Refs lance#6755. * test(lance): assert created_at-preserved + updated_at-bumped on merge_insert UPDATE Addresses PR #229 review follow-up. `lance_merge_insert_update_preserves_created_at_version` documented (in a comment) that a merge_insert UPDATE preserves created_at and bumps updated_at, but only asserted the value change — leaving the change-feed invariant unguarded. Add the two missing assertions: - bob created_at == v1 (preserved across UPDATE; what the test name promises; lance#6774 only changed INSERT-row stamping). - bob updated_at == v2 (bumped to the commit version) — the invariant OmniGraph's insert/update classification relies on (changes/mod.rs keys on _row_last_updated_at_version). A regression here would silently drop updates from the diff/change feed. |

fix(engine): scalar index coverage + filter literal coercion (query latency) (#216)
* fix(engine): lower date/datetime filter literals as typed Arrow scalars `literal_to_expr` lowered `Date`/`DateTime` query literals as Utf8 strings, relying on DataFusion implicit casts. Against a physical `Date32`/`Date64` column that can coerce the column side (`CAST(col AS Utf8)`), which defeats a scalar BTREE and degrades the scan to a full filtered read. Lower to typed `Date32`/`Date64` scalars instead (reusing the loader's `parse_date32_literal`/`parse_date64_literal`, already used by the in-memory comparison arm), so the predicate stays a direct column comparison and the index is used. Malformed literals fall back to the Utf8 string so pushdown behavior never regresses. Tests: unit goldens asserting the lowered literal is typed (red before, green after) + inline-binding pushdown equality in literal_filters confirming the epoch conversion selects the right rows. * fix(engine): build scalar BTREE for enum and orderable-scalar @index columns `build_indices_on_dataset_for_catalog` only handled `String` (-> FTS) and `Vector` (-> vector). Enums are physically `String`, so an enum `@index` column (e.g. `status`) got an FTS inverted index, which Lance never consults for `=`; and `DateTime`/`Date`/numeric/`Bool` `@index` columns fell through and built nothing. Both meant equality/range filters degraded to full scans with `indices_loaded=0`. Dispatch index kind by property type via a shared `node_prop_index_kind`: enum + orderable scalar -> BTREE, free-text String -> FTS, Vector -> vector, list/Blob -> none. The helper is shared by the builder and `needs_index_work_node` so they cannot drift — the latter decides recovery- sidecar pinning, and under-reporting would leave a HEAD-advancing index build uncovered (invariant 5). Tests: scalar_indexes.rs asserts enum/DateTime/numeric @index columns report `IndexCoverage::Indexed` while free-text String/un-annotated columns stay `Degraded` (negative control). Docs: docs/user/indexes.md. * feat(engine): reindex in optimize to keep index coverage current A scalar/FTS/vector index only covers the fragments it was built over. Rows appended after the build (e.g. `ingest --mode merge`, whose commit does not rebuild an existing index) are scanned unindexed, and `compact_files` rewrites fragments out of coverage. Nothing folded them back in, so coverage decayed as the graph grew — even the id/src/dst BTREEs that power traversal. `optimize_one_table` now runs Lance `optimize_indices` after `compact_files` (incremental merge, not retrain — the same compact->optimize_indices sequence LanceDB's `optimize()` uses) and enters the publish path on compaction work OR stale index coverage (new `TableStore::has_unindexed_fragments`, reusing the fragment_bitmap logic). `optimize_indices` is a committing call with no uncommitted variant in lance-6.0.1, so it is an inline-commit residual covered by the existing `SidecarKind::Optimize` recovery sidecar spanning both ops. Blob-bearing tables are still skipped (the Lance blob-compaction bug is compaction-specific; reindex-for-blob deferred as a noted follow-up). Tests: maintenance.rs asserts an appended fragment is uncovered before and covered after optimize, and idempotency holds (second pass is a no-op). lance_surface_guards pins the `optimize_indices` signature and its incremental- coverage behavior. The existing optimize Phase-B recovery failpoint now also exercises a crash after reindex. Docs: maintenance.md, writes.md, invariants.md, lance.md, AGENTS.md. * fix(engine): coerce pushdown filter literals to the column type Filter literals were pushed to Lance in their natural Arrow type (every integer Int64, every float Float64). Against a narrower indexed column DataFusion widens to the literal's type and casts the COLUMN (`CAST(n32 AS Int64)`), which defeats the scalar BTREE and degrades to a full filtered read. A physical-plan probe confirms it: an Int32 column filtered by an i32 literal uses `ScalarIndexQuery`; by an i64 literal it does not. Thread the scan's `arrow_schema` through `build_lance_filter_expr` -> `ir_filter_to_expr` and coerce each literal operand to the opposite column's exact Arrow type, reusing `projection::literal_to_array` + `arrow_cast` (the same path the in-memory arm uses, so the two arms agree). Coercion never demotes a filter to None: on failure it falls back to the natural literal, because a node scan has no in-memory fallback for inline filters. Supersedes the date-specific change in |

(feat) convert engine call sites to &dyn TableStorage; demote legacy TableStore methods to pub(crate) (#86)
* MR-854: convert engine call sites to &dyn TableStorage; demote legacy methods
Phase 1b: every db.table_store.X(...) call site converts to
db.storage().X(...), reaching the storage layer through the sealed
TableStorage trait (returns &dyn TableStorage). Opaque SnapshotHandle
and StagedHandle replace bare lance::Dataset and Transaction in the
threaded values.
Phase 9: the inherent inline-commit methods on TableStore
(append_batch, merge_insert_batch{,es}, overwrite_batch,
create_btree_index, create_inverted_index) demote from pub to
pub(crate). Their only remaining direct users are table_store.rs
itself and the bulk loader's LoadMode::{Append, Overwrite, Merge}
concurrent fast-paths in loader::write_batch_to_dataset (no
two-phase shape in Lance 4.0.0 — closes after lance#6658 and #6666).
Docs:
- invariants.md \u00a7VI.23: drop "at the writer-trait surface"
qualifier; staged primitives are now the only engine surface.
- runs.md: residual matrix shrinks to delete_where and
create_vector_index (the two upstream-blocked residuals).
- forbidden_apis.rs: replace transitional language with the
current allow-list shape (table_store.rs + loader concurrent
fast-path only).
Files touched:
- changes/mod.rs, db/omnigraph.rs (+export/optimize/schema_apply/
table_ops.rs), exec/{merge,mod,mutation,staging}.rs,
loader/mod.rs, storage_layer.rs, table_store.rs,
tests/forbidden_apis.rs, docs/{invariants,runs}.md.

* MR-854: replace test-only inline-commit append callers with local Lance helpers
After demoting TableStore::append_batch from pub to pub(crate), the
integration tests in tests/recovery.rs and tests/staged_writes.rs
that previously called store.append_batch(...) directly to simulate
HEAD-ahead-of-manifest drift can no longer access the inherent
method. Replace those calls with small in-test helpers that do a raw
Dataset::append (the same body the inherent method runs).
- tests/helpers/mod.rs gains lance_append_inline (shared helper).
- tests/staged_writes.rs gets a file-local lance_append_inline_local
(staged_writes.rs does not import helpers::).
- tests/recovery.rs drops the unused TableStore import in the one
function whose store binding became unused after the conversion.

* MR-854: retrigger CI for flaky Test Workspace job
Co-Authored-By: Ragnor Comerford <ragnor.comerford@gmail.com>
* MR-854: convert remaining table_store call sites in export.rs / read_blob
Two leftover `self.table_store.X` / `db.table_store.X` call sites were
missed in the initial sweep — flagged by Devin Review on PR #86. Both
now go through the trait surface:
- `entity_from_snapshot` (db/omnigraph/export.rs): switch from
`db.table_store.open_snapshot_table` + `db.table_store.scan` to
`db.storage().open_snapshot_at_table` + `db.storage().scan`.
- `read_blob` (db/omnigraph.rs): replace
`snapshot.open(table_key)` + `self.table_store.first_row_id_for_filter`
with `self.storage().open_snapshot_at_table` +
`self.storage().first_row_id_for_filter`. The follow-up
`take_blobs` call still needs an `Arc<Dataset>` (it's a Lance blob
accessor not surfaced through the trait), so we hand off via
`SnapshotHandle::into_arc()` with a comment.
After this commit, no engine code outside `table_store.rs` reaches the
inherent `TableStore` API — the docs/runs.md and docs/invariants.md
claim is now uniformly true.

* MR-854: post-rebase doc fixes (Lance 6.0.1, MR-A framing, into_dataset note)
Reviewer feedback on the rebased PR:
* docs/dev/writes.md residuals matrix: drop demoted methods from the trait-surface table (now `pub(crate)`); keep only the two genuine trait-surface residuals (`delete_where`, `create_vector_index`); reframe under MR-A (Lance v7.x bump) per docs/dev/lance.md.
* tests/forbidden_apis.rs: update transitional allow-list header to (a) drop the truncate_table mislabel (truncate_table is a Lance Dataset method, not a TableStore method — overwrite_batch's internal call), (b) reframe trait-surface residuals under MR-A / Lance #6666.
* crates/omnigraph/src/storage_layer.rs::SnapshotHandle::{into_arc, into_dataset}: add single-ref invariant doc — both consume Arc via try_unwrap-or-clone; sibling SnapshotHandle clones across an await point force a deep Dataset clone.
* Replace lance-4.0.0 version refs with lance-6.0.1 in active source/test/dev-doc comments (storage_layer.rs, table_store.rs, table_ops.rs, schema_apply.rs, merge.rs, recovery.rs, staged_writes.rs, consistency.rs, docs/dev/execution.md, docs/user/query-language.md). Historical refs in docs/releases/v0.4.1.md and the canonical "Lance 4.0.0 → 6.0.1 migration" line in docs/dev/lance.md left intact.
No engine code changes.
* MR-854: update docs/dev/invariants.md Storage trait row + gap entry
Reviewer feedback: the docs reorg landed; the invariant row now lives in
docs/dev/invariants.md with stable headings (no more numbered §VI.23).
Update two pieces to reflect MR-854 completion:
* Status table 'Storage trait' row: was 'full call-site migration ... incomplete';
now 'engine call sites all route through db.storage() (MR-854); inline-commit
inherent methods are pub(crate)-demoted; capability/stat surfaces are roadmap'.
* 'Known Gaps' 'Storage abstraction' entry: was 'older inherent TableStore call
sites and inline residuals remain'; now names the closed scope (MR-854 — call
sites migrated, methods demoted, loader fast-paths) and the remaining
trait-surface residuals under MR-A (Lance v7.x bump) and Lance #6666.
Cross-links to docs/dev/lance.md and docs/dev/writes.md so the framing stays
co-located with the canonical Lance surface tracking.
* MR-854: remove dead inline-commit methods from the storage surface
The loader concurrent fast-path (write_batch_to_dataset) is only reached
for LoadMode::Overwrite — Append/Merge route through MutationStaging — so
its Append/Merge arms were unreachable. Collapse it to overwrite-only and
drop the now-unused mode params, which removes the only callers of:
- TableStorage::append_batch + TableStorage::merge_insert_batches (trait)
- TableStore::merge_insert_batch + merge_insert_batches (inherent)
create_btree_index / create_inverted_index had zero callers anywhere
(scalar index builds use the stage_* primitives). Remove both from the
trait and the inherent impl.
Inherent append_batch stays pub(crate): overwrite_batch and recovery
tests use it. Migrate the one trait-append_batch test caller
(seed_person_row) to stage_append + commit_staged. The merge_insert
FirstSeen-workaround rationale moves from the deleted merge_insert_batch
into stage_merge_insert (now the sole merge path). No behavior change.
Also corrects the inaccurate loader residual comment (the prior text
blamed Lance #6658/#6666, which are the delete and vector-index issues,
for keeping overwrite inline; a stage_overwrite primitive already exists
and schema_apply uses it).
* MR-854: seal db.storage() to staged-only; move residuals to InlineCommitResidual
Split the three remaining inline-commit writes (overwrite_batch,
delete_where, create_vector_index) off the TableStorage trait onto a new
sealed InlineCommitResidual trait, reachable only via the explicit
Omnigraph::storage_inline_residual() accessor. db.storage() now exposes
only staged primitives + reads, so engine code cannot couple a write
with a Lance HEAD advance through the default surface — MR-793 acceptance
§1 ("no public method commits as a side effect of writing") now holds by
construction, not by review + naming.
Call sites moved to storage_inline_residual(): loader overwrite
fast-path, the three mutation delete_where paths, the branch-merge
delete, and the vector-index build. Impl bodies are unchanged (same
delegation to the pub(crate) inherent methods); this is a pure surface
reshape with no behavior change.
The residual trait holds two genuinely upstream-blocked methods
(delete_where -> Lance #6658/v7.x, create_vector_index -> Lance #6666)
plus overwrite_batch, kept for the loader's cross-table bulk-overwrite
concurrency until its staged migration lands (tracked follow-up).
* MR-854 docs: describe the staged-only seal; fix stale Lance index URLs
- writes.md / invariants.md / AGENTS.md: the inline-commit residuals now
live on InlineCommitResidual behind db.storage_inline_residual(), so
acceptance §1 holds by construction rather than 'option (b)' per-method
enumeration. Drop the inaccurate 'until Lance exposes
Operation::Overwrite { fragments }' claim (that op exists; stage_overwrite
already builds it) and reframe overwrite_batch as a removable legacy
residual gated on the loader's bulk-overwrite concurrency.
- forbidden_apis.rs: rewrite the allow-list doc for the split surface.
- lance.md: the index spec pages moved from /format/table/index/ to
/format/index/ in Lance 6.x (the old paths 404). Fix all 13 URLs.
* MR-854: fix stale lance-4.0.0 comment refs flagged in review
Addresses greptile (exec/merge.rs) and aaltshuler's stale-version blocker:
update lance-4.0.0 -> 6.0.1 in the comment/doc refs within this PR's
footprint (exec/merge.rs, exec/mutation.rs, docs/dev/writes.md). Also
corrects exec/merge.rs to cite lance#6666 (not #6658) for
build_index_metadata_from_segments — that is the vector-index segment-commit
API; #6658 is the two-phase delete. (Pre-existing 4.0.0 refs in untouched
files like architecture.md/storage.md are main's incomplete migration
cleanup, left out of scope.)
* fix(storage): stage loader overwrites
* fix(storage): stage empty schema rewrites

* test(optimize): pin Lance blob-column compaction failure as a surface guard
Lance compact_files mis-decodes blob-v2 columns under its forced BlobHandling::AllBinary read ("more fields in the schema than provided column indices"), failing even a pristine uniform-V2_2 multi-fragment blob table; reads use descriptor handling and are unaffected.
Guard 10 reproduces this and is self-retiring: it turns red on the Lance bump that fixes the bug, forcing LANCE_SUPPORTS_BLOB_COMPACTION to flip.
* fix(optimize): skip blob-bearing tables instead of crashing compaction
omnigraph optimize aborted the whole sweep when any node/edge table had a Blob property: Lance compact_files cannot decode blob-v2 columns under AllBinary (the column-index error pinned by the surface guard). Skip blob-bearing tables behind a LANCE_SUPPORTS_BLOB_COMPACTION gate and report them via TableOptimizeStats.skipped / SkipReason (surfaced in the CLI and a tracing::warn) instead of erroring, which also isolates the failure so the other tables still compact.
Reads/writes are unaffected; only fragment/space reclamation on blob tables is deferred until the upstream Lance fix. Adds a maintenance.rs regression test (validated red with the column-index symptom before the fix, green after), a concise v0.6.1 release note, and updates docs (maintenance, cli-reference, AGENTS capability matrix, invariants Known Gaps, lance.md audit, constants).
* refactor(optimize): make TableOptimizeStats and SkipReason non_exhaustive
Both are returned result types, never built by callers, so #[non_exhaustive] makes this the last field/variant addition that can break downstream literal construction and keeps future ones non-breaking (review feedback on the public-field addition). The v0.6.1 Compatibility Notes call out the source-level change.
Also drops the now-stale "RED today / GREEN after the fix lands" narration in the optimize_skips_blob_table_and_reports_skip test (historical regression context now that the fix is in this branch), and folds in the expanded v0.6.1 release note.
* chore(release): bump workspace to v0.6.1
Coherent version bump to accompany the v0.6.1 release note: all five crate manifests + path-dependency constraints, Cargo.lock, the AGENTS.md surveyed-version line, and openapi.json info.version move 0.6.0 -> 0.6.1. Matches the established release pattern (#118 landed the v0.6.0 note + bump together) and resolves the Codex/Devin review flag that a v0.6.1 note without a bump leaves CARGO_PKG_VERSION reporting 0.6.0 and mixed package versions.

fix(branch): make branch delete correct under partial failure (#137)
* test(lance): pin force_delete_branch surface guard
Pin the Lance 6.0.1 force_delete_branch behavior the branch-delete
single-authority redesign relies on: plain delete_branch errors on a
missing ref, force_delete_branch removes an existing forked branch, and
the local-store quirk where force_delete on a fully-absent branch still
errors (worked around by the upcoming TableStore::force_delete_branch).
Re-pin the docs/dev/lance.md alignment stanza (9 guards; 4 runtime).
* feat(storage): add force branch-delete to TableStore + CommitGraph
Add TableStore::force_delete_branch and CommitGraph::force_delete_branch
(idempotent: tolerate an already-absent branch via Lance RefNotFound /
NotFound), plus CommitGraph::list_branches for the cleanup reconciler to
diff against the manifest authority. RefConflict (referencing
descendants) is still surfaced. Unused until the branch-delete rewire.
* test(maintenance): red — cleanup reconciles orphaned branch forks
Forge a Lance branch on the Person table that the manifest never
references (a zombie fork from an incomplete prior delete) and assert
cleanup reclaims it while leaving main intact. Fails today: cleanup does
not yet reconcile orphaned forks. Goes green with the next commit.
* fix(maintenance): reconcile orphaned branch forks in cleanup
Add reconcile_orphaned_branches: force_delete_branch every per-table and
commit-graph Lance branch absent from the manifest branch set (the
authority), children-before-parents. Folded into cleanup_all_tables,
runs before version GC. Idempotent and authority-derived; no-ops once
nothing is orphaned, and would harmlessly find nothing if a future Lance
atomic multi-dataset branch op prevented orphans. Adds TableStore::list_branches
and exposes graph_commits_uri(pub crate). Turns the maintenance red test green.
* test(failpoints): red — branch_delete partial failure converges
Add the branch_delete.before_table_cleanup failpoint hook (inert without
the feature) and a regression test: a cleanup-step failure after the
manifest authority flip must leave branch_delete returning Ok, the branch
gone, the orphan stranded, then reclaimed by cleanup, and the name
reusable. Fails today: cleanup_deleted_branch_tables propagates the error
as a hard failure. Goes green with the next commit.
* fix(branch): best-effort fork reclaim after the manifest flip
Make branch_delete treat per-table forks and the commit-graph branch as
derived state reclaimed best-effort with force_delete_branch after the
manifest authority flip. A reclaim failure (transient error, or the
branch_delete.before_table_cleanup failpoint) is logged via tracing::warn
and swallowed: the branch is already gone and the cleanup reconciler
converges the orphan. cleanup_deleted_branch_tables no longer returns an
error or blocks the call. Turns the partial-failure recovery test green.
* test(failpoints): red — recreate over orphaned fork is actionable
After a partial-failure delete leaves a fork orphaned, recreating the
branch name and writing to the previously-forked table before cleanup
runs currently surfaces the opaque ExpectedVersionMismatch ("stale view
... expected manifest table version N"). Assert instead a clear error
pointing the user at cleanup. Goes green with the next commit.
* fix(branch): actionable orphan-collision error in fork_branch_from_state
When a fork's create_branch collides with an existing target ref, reuse
it only if its head matches source_version (a legitimate concurrent
first-write). A version mismatch means a zombie fork from an incomplete
prior delete: return a manifest_conflict pointing the user at
`omnigraph cleanup`, instead of the opaque ExpectedVersionMismatch.
Turns the recreate-over-orphan red test green.
* docs(invariants): single-authority branch-lifecycle + Lance forward-compat
Record branch delete in the Current Truth Matrix: manifest is the single
authority flipped atomically first, per-table forks + commit-graph branch
are derived state reclaimed best-effort with the cleanup reconciler as
backstop, and reusing a name whose reclaim failed surfaces an actionable
error. Note the reconciler is authority-derived and degrades to a no-op
under a future Lance atomic multi-dataset branch op, the same shape as
invariant 7.
* test(failpoints): red — cleanup isolates a single-table failure
Add the cleanup.table_gc failpoint hook (inert without the feature) and
an error: Option<String> field on TableCleanupStats (mechanical, always
None for now). Regression test: a one-shot version-GC failure for one
table must not abort the whole cleanup — assert cleanup still succeeds,
surfaces the failure per-table in stats, and the independent reconcile
pass still reclaimed an orphan. Fails today: the version-GC collect
aborts on the first table error. Goes green with the next commit.
* fix(maintenance): fault-isolate cleanup per table
Make the cleanup sweep do as much as it can and converge on re-run
instead of aborting wholesale on one table's transient error
(invariant 13). The version-GC loop now records a per-table failure on
its stats row (error: Some) and logs it rather than collecting into a
Result that aborts; reconcile_orphaned_branches isolates per-table and
commit-graph failures into BranchReconcileStats.failures. The CLI reports
any failed tables and tells the user to rerun cleanup. Addresses the
Devin review finding. Turns the single-table-failure test green.
* test(failpoints): red — branch_create heals commit-graph zombie + is atomic
Add the branch_delete.before_commit_graph_reclaim failpoint hook and two
regression tests: (a) recreating a name whose delete left a commit-graph
zombie must succeed (today it dies on Lance's internal Clone error), and
(b) branch_create must roll back the manifest branch when the derived
commit-graph branch fails (today it leaves the manifest branch created
while returning Err). Both fail now; green with the next commit. The
existing branch_create_failpoint_triggers test still passes.
* fix(branch): make branch_create atomic + heal commit-graph zombie
branch_create now flips the manifest authority first, then creates the
derived commit-graph branch in create_commit_graph_branch, force-dropping
any orphaned commit-graph ref left by an incomplete prior delete (the
manifest branch is fresh, so a same-named commit-graph branch is provably
a zombie). If commit-graph creation fails, the manifest branch is rolled
back so the name never half-exists. Addresses the Codex review finding.
Turns the two branch_create red tests green; existing tests unaffected.
* test(failpoints): red — fork collision misclassifies live concurrent fork
Add the fork.before_classify failpoint hook and a concurrency test: when
a concurrent first-write legitimately wins the fork race, the loser must
get a retryable refresh-and-retry, not the misleading run-cleanup orphan
error. Today the version-comparison misclassifies the live fork as an
orphan (the Cursor finding). Goes green with the next commit.
* fix(branch): manifest-arbitrated fork-collision classification
Classify a fork collision by the manifest authority instead of comparing
Lance branch versions. Before forking, open_owned_dataset_for_branch_write
re-reads the live manifest: if the table is already forked on the active
branch, a concurrent first-write won and the loser gets a retryable
refresh-and-retry (not a misleading orphan error). fork_branch_from_state
no longer guesses from versions — a create collision past that check is
an orphan, so it returns the actionable cleanup error. Addresses the
Cursor finding; turns the live-concurrent-fork test green, zombie path
unchanged.
* test(failpoints): close branch-lifecycle test gaps
Three coverage additions for the branch-delete work (behavior already
correct; these lock it in and catch regressions):
- cleanup_isolates_reconcile_failure: inject a force-delete failure into
the reconcile loop (new cleanup.reconcile_fork hook) and assert the
sweep continues + converges on re-run. Directly covers the reconcile
loop the Devin finding was about (previously only version-GC was).
- cleanup_reclaims_orphaned_commit_graph_branch: forge a commit-graph
orphan via the delete reclaim failpoint and assert cleanup's
reconcile_commit_graph_orphans drops it (previously untested).
- fork_collision_with_live_concurrent_fork_is_retryable: replace the
fixed 300ms sleep with a deterministic readiness signal (cfg_callback +
compare_exchange atomics) so the two-writer ordering can't flake.
Full failpoints suite 31/0.

chore(lance): bump 4.0.0 → 6.0.1 (DataFusion 52→53, Arrow 57→58) (#111)
* tests: add lance_surface_guards pre-flight pins for the v6 bump
Land 8 named guards in a new test file that pin Lance API surfaces
OmniGraph relies on. Each guard turns a silent-break risk (variant
rename, struct restructure, async-flip) into a red CI bar instead of
runtime drift.
Guards (mapped to the silent-break inventory from the v6 migration plan):
Runtime (#[tokio::test]):
1. lance_error_too_much_write_contention_variant_exists — pins the
variant referenced by db/manifest/publisher.rs::map_lance_publish_error.
2. manifest_location_field_shape — pins .path/.size/.e_tag/.naming_scheme
types and ManifestLocation accessor returning &Self (the access
pattern at db/manifest/metadata.rs:84-88).
6. write_params_default_does_not_set_storage_version — confirms our
explicit V2_2 pin remains load-bearing (blob v2 requirement).
Compile-only async fns (#[allow(...)] + unimplemented!() placeholders;
never run, but cargo build --tests enforces the API shape):
3. checkout_version + restore chain — pins the recovery rollback hammer
at db/manifest/recovery.rs:505-522.
4. DatasetBuilder::from_namespace().with_branch().with_version().load()
— pins the namespace builder chain at db/manifest/namespace.rs:162-174.
5. MergeInsertBuilder fluent chain — pins the manifest CAS at
db/manifest/publisher.rs:370-391, including the return shape
(Arc<Dataset>, MergeStats).
7. compact_files(&mut ds, CompactionOptions, None) — pins
db/omnigraph/optimize.rs:107.
8. DeleteResult { new_dataset, num_deleted_rows } — pins the inline
delete result shape (MR-A will repurpose this guard to the staged
two-phase variant once Lance #6658 migration lands).
This is commit 1 of the chore/lance-6.0.1 migration. Cargo bump
follows in commit 2 (will trigger the guards under v6 if any surface
drifted).
Per the migration plan at ~/.claude/plans/shimmering-percolating-duckling.md
(written this session). Two guards from the plan deferred to follow-up:
- manifest_cas_returns_row_level_contention_variant (full publisher
race integration test — needs harness scaffolding)
- table_version_metadata_byte_compatible_with_v4 (TableVersionMetadata
is pub(crate); requires test reach extension).
Verified on v4: cargo test -p omnigraph-engine --test lance_surface_guards
passes 3/3 runtime tests; cargo build -p omnigraph-engine --tests
compiles all 5 compile-only guards clean.

* chore(deps): bump Lance 4.0.0 → 6.0.1, DataFusion 52 → 53, Arrow 57 → 58
The Cargo bump itself. Source is intentionally untouched — this commit
will not compile. The compile errors are the work-list for subsequent
commits on this branch.
Lance updates: lance + 7 sub-crates 4.0.0 → 6.0.1. Transitive churn:
+ lance-tokenizer v6.0.1 (vendored tokenizer per Lance PR #6512)
+ object_store 0.13.x (Lance 6 brings it transitively; our explicit
pin stays at 0.12.5 for now — revisit in stages if diamond bites)
- tantivy* crates (replaced by lance-tokenizer)
Compile error landscape on this commit (11 errors):
• 1× E0432: `lance_index::DatasetIndexExt` import (Lance PR #6280
moved it to lance::index). Sites: table_store.rs:20,
db/manifest.rs:37 (the second site was missed by the pre-flight
inventory).
• 8× E0599: `create_index_builder` / `load_indices` missing on
`lance::Dataset` — all downstream of the DatasetIndexExt move.
Once the import is corrected on table_store.rs and db/manifest.rs,
these resolve automatically.
• 2× E0063: missing field `is_only_declared` in `DescribeTableResponse`
initializer at db/manifest/namespace.rs:221, 364. New Lance
namespace field per the v5 namespace restructure (PR #6186).

docs: drop npx mdrip; use curl | pandoc for full-page fetches (#97)
The previous "fetch the full page" recommendation in AGENTS.md and docs/dev/lance.md pointed at an unknown-author npm CLI that, on consent, wrote agent-targeted content into AGENTS.md and modified .gitignore / tsconfig.json. Source audit was clean of malicious code but the self-perpetuating prompt-injection pattern combined with a single maintainer and ~21 downloads/day made it not worth the risk. Switched to the curl + pandoc command already documented as the no-tool option. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
