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. |

feat(cli): plane-grouped --help + clap 4.6.1 (RFC-010 Slice 2) (#220)
* chore(deps): bump clap to 4.6.1
Workspace constraint "4" → "4.6" so the resolver picks up the 4.6 line
(a plain `cargo update` stayed on 4.5.x). clap 4.5.58 → 4.6.1
(clap_builder 4.6.0, clap_derive 4.6.1). Minor bump, no API breakage; the
workspace builds and all CLI suites pass unchanged.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(cli): group --help by plane (RFC-010 Slice 2)
Slice 1 declared the planes (the command_plane table + the wrong-plane
guard); this makes them visible in `--help`. clap can't print labeled
heading rows between subcommand groups (verified against the source —
help_heading is args-only, {subcommands} is one flat block), so per the
chosen approach: cluster + legend.
- Reorder the `Command` enum into plane bands (clap lists subcommands in
declaration order): data (query, mutate, load, branch, snapshot, export,
commit, schema, graphs) → storage/local-graph ops (init, optimize,
repair, cleanup, lint, queries) → control (cluster) → session (policy,
embed, login, logout, config, version). No magic display_order numbers —
the source order IS the help order, with band comments for readers. The
band placement matches `command_plane` (lint/queries are storage-plane:
they reject --server), so the help grouping and the guard agree.
- Add an `after_help` legend on `Cli` naming the planes. Written to
describe the planes (not enumerate every command) so it doesn't drift.
Help-polish (post-review): hide the deprecated `ingest` from the list
(still a valid command); trim the long `login` and `--as` descriptions to
one line each so the columns don't blow up.
The behavioral source of truth for planes stays `planes::command_plane`;
this ordering is its cosmetic counterpart.
Test: `help_groups_commands_by_plane` pins the legend phrase + the cluster
ordering (query < optimize < cluster). Doc: a line under cli-reference's
*Command planes* section.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(cli): qualify mixed-plane commands in the --help legend
Addresses the Greptile P2 on #220: the legend placed `schema` entirely in
Data and `queries` entirely in Storage, but per `command_plane` the
subcommands differ — `schema plan` is storage-plane (rejects --server) and
`queries list` is session (no graph). A user reading the legend then running
`schema plan --server` would hit a rejection contradicting it. The Commands
list is one entry per top-level command (necessarily coarse), so the legend
carries the nuance: `schema [plan: storage]` and `queries [list: session]`.

refactor(api): extract omnigraph-api-types crate (RFC-009 Phase 2)
The HTTP wire DTOs and their engine-result -> DTO mappings move from omnigraph-server's api module into a new omnigraph-api-types crate that both server and CLI can depend on (engine must not — DAG: api-types -> engine, never the reverse). The crate holds plain serde/utoipa types only; the transport-coupled error->status mapping stays in the server (lib.rs/ handlers). The one server-runtime coupling (query_catalog_entry, which maps a StoredQuery — not a wire type) stays behind in api.rs, now calling the crate's pub param_descriptor. api.rs becomes a thin `pub use omnigraph_api_types::*` re-export, so every omnigraph_server::api::Foo path (handlers, the OpenApi schema list, CLI imports) resolves unchanged. openapi.json regenerates BYTE-IDENTICAL (the Phase-2 referee: 77 openapi tests green, zero diff).

Recovery liveness, storage fault-injection matrix, and one storage implementation over object_store (#203)
* test(engine): pin the long-lived-handle heal contract for sidecar-covered drift
A Phase B -> Phase C failure (commit_staged advanced Lance HEAD, manifest
publish did not land, recovery sidecar persists) currently wedges every
subsequent staged write on the same engine handle: the commit-time drift
guard rejects with 'run omnigraph repair', but repair itself refuses
while a recovery sidecar is pending, so a long-lived server can only
recover by restart. The documented contract (writes.md 'Long-running
servers', invariants.md invariant 5) says refresh-time roll-forward
closes this residual without restart -- but no write path runs it.
Two red tests pin the intended contract at the write entry points:
a follow-up load (the POST /ingest shape: shared handle, no reopen)
and a follow-up mutation must heal roll-forward-eligible sidecars
in-process and then succeed.
Currently failing with:
table 'node:Company' has Lance HEAD version 2 ahead of manifest
version 1; run `omnigraph repair` before writing
The fix lands in the next commit.
* fix(engine): heal pending recovery sidecars at the staged-write entry points
Close the long-lived-process gap in the recovery protocol: a Phase B ->
Phase C residual (per-table commit_staged landed, manifest publish did
not, sidecar persists) previously recovered only at the next ReadWrite
open or via an explicit refresh() that no production write path called,
so a long-lived server wedged every subsequent write on the commit-time
drift guard until restart.
New recovery::heal_pending_sidecars_roll_forward:
- one list_dir of __recovery/ at write entry (empty -> immediate
return, the steady state), so the per-write cost is one storage list;
- per sidecar, acquires the same per-(table_key, table_branch) write
queues every sidecar writer holds from before write_sidecar until
after delete_sidecar, then re-checks sidecar existence -- this
serializes the heal against live writers instead of rolling an
in-flight sidecar forward from under its writer (which would fail
that writer's publish CAS spuriously). Lock order queues ->
coordinator matches every writer's commit->publish path. This is the
queue-acquisition design recovery.rs and write_queue.rs already
documented for in-process recovery;
- processes in RollForwardOnly mode: the common residual rolls forward
in-process; rollback-eligible sidecars still defer to the next
ReadWrite open (Dataset::restore is unsafe under concurrency).
Wire it into load_as and mutate_as (before the inline delete path can
advance any HEAD), and rebase Omnigraph::refresh onto the same helper
so refresh stops racing live writers' sidecars.
The maintenance entry points (apply_schema_as, branch_merge_as,
ensure_indices) intentionally keep their strict fail-loud preconditions
for now; wiring the same heal there is a follow-up with its own tests.
Turns the previous commit's two red tests green.
* fix(engine): name the right recovery path in the commit-time drift guard
The drift guard's 'run omnigraph repair before writing' advice is a
dead end when the drift is covered by a pending recovery sidecar:
repair refuses while a sidecar is pending. With the write-entry heal in
place, reaching this guard with sidecar-covered drift means the heal
deferred it (rollback-eligible), and the actual recovery path is a
read-write reopen. Distinguish the two classes on the error path only
(one sidecar list, after the conflict is already certain); a listing
failure falls back to the uncovered-drift wording rather than masking
the conflict.
Pinned by extending refresh_defers_rollback_eligible_sidecar_to_next_open
with a write attempt against the deferred sidecar.
* docs: write-entry in-process sidecar heal — contract and coverage
Update the recovery contract docs to match the previous two commits:
invariant 5 now states that the staged-write entry points and refresh
run in-process roll-forward recovery (long-lived processes converge on
the next write, not at restart); writes.md 'Long-running servers'
describes the heal's queue-acquisition concurrency contract, the
improved drift-guard error, and the entry points that intentionally do
not heal yet; testing.md indexes the new failpoint tests; AGENTS.md
capability matrix drops the claim that in-process recovery is entirely
future work (only the rollback path remains with the background
reconciler).
* test(engine): pin the entry heal contract for schema apply and branch merge
Without the write-entry heal, the two maintenance writers do worse than
wedge on sidecar-covered drift -- they proceed and decide its fate
implicitly:
- schema apply re-plans table rewrites from the manifest pin, orphaning
the drifted Phase-B commit (its rows silently vanish from the
rewritten table) while the stale sidecar lingers to misclassify
against the post-apply pins;
- branch merge publishes over the drift, making the failed writer's
commit visible as an unattributed side effect (no recovery audit
row), and leaves the stale sidecar behind.
Two red tests pin the intended contract: both entry points heal the
sidecar first (attributed roll-forward), then run on the converged
state. Currently failing on the stale-sidecar / dropped-rows
assertions; the fix lands in the next commit.
* fix(engine): heal pending recovery sidecars at the schema-apply and branch-merge entries
Extend the write-entry heal to the remaining two write entry points.
Unlike load/mutate (which wedge on the drift guard), these proceeded
over sidecar-covered drift and decided its fate implicitly:
- schema apply re-planned table rewrites from the manifest pin,
orphaning the drifted Phase-B commit -- its rows silently vanished
from the rewritten table -- while the stale sidecar lingered to
misclassify against the post-apply pins;
- branch merge published over the drift, making the failed writer's
commit visible without a recovery audit row, and left the stale
sidecar behind.
Both now run the same queue-serialized roll-forward heal at entry,
before their own sidecar exists, so recovery is attributed (audit row)
and deterministic. ensure_indices stays heal-free: it runs inside the
load / schema-apply flows after their entry heal.
Turns the previous commit's two red tests green. Docs updated in the
same change (invariant 5, writes.md, testing.md, AGENTS.md).
* test(engine): pin Phase A sidecar-write failure semantics
Storage fault-injection matrix, row 1: a sidecar PUT failure (S3
PutObject / fs write) in Phase A. New failpoint recovery.sidecar_write
at the top of write_sidecar -- the single choke point all five sidecar
writers go through -- models the storage error backend-generically.
Also adds the other three storage-fault failpoints used by the
following commits (recovery.sidecar_delete, recovery.sidecar_list,
recovery.record_audit); each is a no-op without the failpoints feature.
Pinned contract: every writer writes its sidecar BEFORE its first
HEAD-advancing commit, so a put failure aborts with zero drift (no
sidecar, Lance HEAD == manifest pin, no rows) and a transient fault
never wedges the graph -- the same handle writes/merges normally once
it clears. Covered for load (the staging writer) and branch_merge (the
multi-table writer, forced onto the RewriteMerged path by diverging
both sides).
* test(engine): pin Phase D delete, list, and audit-append storage-fault semantics
Storage fault-injection matrix, rows 2/3/5, plus the real-backend run:
- recovery.sidecar_delete: a Phase D delete failure (S3 DeleteObject)
must NOT fail the user's write -- the manifest publish already
landed, so the caller's data is durable. The swallowed failure
leaves a stale sidecar; the next write's entry heal consumes it via
the stale-sidecar audit-recovery path (RolledForward, attributed).
- recovery.sidecar_list: a __recovery/ list failure (S3 ListObjectsV2)
is loud at every consumer -- the write-entry heal fails the write
and the open-time sweep fails the open. Silently skipping recovery
over a pending sidecar would be consumer tolerance of drift. Once
the fault clears, open recovers the pending sidecar normally.
- recovery.record_audit: an audit write failure after the
roll-forward's manifest publish aborts that recovery attempt and
keeps the sidecar; re-entry detects the already-published manifest,
records exactly ONE RolledForward audit row, and converges -- the
retry tolerance documented on record_audit, exercised end-to-end.
- s3_load_recovers_after_publisher_failure_without_reopen: the
same-handle heal scenario on a real bucket (gated on
OMNIGRAPH_S3_TEST_BUCKET, skips locally), exercising sidecar
put/list/delete through S3StorageAdapter instead of the local-FS
adapter. CI wiring lands in a follow-up commit.
* test(engine): refuse corrupt recovery sidecars loudly
Storage fault-injection matrix, row 4 (no failpoint needed -- the
corrupt file is written by hand, sibling to the unknown-schema-version
refusal test): a truncated/garbage __recovery/{ulid}.json must be
refused loudly by both the write-entry heal (the write fails naming
the parse error) and the open-time sweep (ReadWrite open fails naming
the file), with the file left on disk for operator inspection.
Read-only opens still work -- the sweep is skipped there.
* test(engine): run the S3 sidecar-lifecycle coverage in CI + document the fault matrix
- ci.yml rustfs_integration: new step running the bucket-gated
failpoints tests (name filter s3_) against the RustFS container, so
sidecar put/list/delete are exercised through S3StorageAdapter on
every storage-affecting PR.
- writes.md: sidecar I/O failure semantics -- Phase A put failure
aborts with zero drift; Phase D delete failure is swallowed (write
already durable) and healed by the next write; list failures are
loud at heal and open; corrupt sidecars are refused with the file
kept for inspection; audit-append failures are retried to exactly
one audit row.
- testing.md: index the storage-fault matrix in the failpoints.rs row
and the new RustFS CI line.
* test(engine): pin read-visibility of acknowledged local if-absent writes
The cluster lib test import_missing_state_creates_state_with_graph_-
observation flakes at ~50% under full-workspace load ('EOF while
parsing a value' reading back the state.json its own import just
acknowledged). Root cause is in the engine's local storage adapter:
write_text_if_absent writes through a buffered tokio::fs::File and
returns when write_all resolves -- which, per tokio's documented File
semantics, means the bytes reached tokio's internal buffer, not the
file. The actual write completes in a background blocking task after
drop, so a caller that acknowledges success and reads the object back
can see an empty or partial file. Under load the window widens; the
red run fails at iteration 0 with 0 of 8192 bytes on disk.
The regression test pins the contract at the adapter boundary: when
write_text_if_absent resolves, the full contents are visible to any
reader; a losing second claim leaves the winner's object untouched.
The fix lands in the next commit.
* fix(engine): publish local storage writes with atomic visibility
Close the class, not the instance. The local adapter admitted three
ways for a reader to observe a write that was acknowledged or visible
before its bytes were complete:
1. write_text_if_absent acknowledged success when the buffered
tokio::fs::File write_all resolved -- i.e. when the bytes reached
tokio's internal buffer, not the file. A caller reading back its own
acknowledged write could see an empty object (the ~50% cluster
import flake under full-workspace load; the regression test failed
at iteration 0 with 0 of 8192 bytes visible).
2. The same call published its CLAIM (create_new) before its CONTENT,
so concurrent readers saw an empty claimed file in the window.
3. write_text (plain tokio::fs::write) exposed truncated content
mid-replace -- silently falsifying write_sidecar's 'readers either
see the complete sidecar or none' contract on local FS (true on S3,
where PutObject is atomic).
A flush in write_text_if_absent would have fixed only (1). Instead,
both local write paths now publish complete temp files atomically:
rename for replace (write_text -- the idiom write_text_if_match
already used) and hard_link for no-replace (write_text_if_absent --
link fails AlreadyExists, so exactly one of N concurrent claimants
wins and the winner's object is fully readable at the instant it
becomes visible). The local adapter now honors the same object-level
atomic-visibility contract as the S3 adapter, which is what every
caller (recovery sidecar protocol, cluster state CAS) was written
against. Crash-orphaned *.tmp.* files are inert: the sidecar sweep
filters to .json, and cluster state reads address state.json by name.
fsync/durability policy is unchanged (no fsync before, none now);
this fix is about visibility ordering, not power-loss durability.
Pre-existing on main (landed with the multi-graph server mode change,
PR #119); surfaced by this branch's heal work only because one extra
list_dir per write shifted test timing. Cluster lib suite: 12/25
failures before, 0/25 after. Turns the previous commit's red test
green.
* refactor(engine): one storage implementation over object_store for every backend
Collapse LocalStorageAdapter (hand-rolled tokio::fs) and
S3StorageAdapter into a single ObjectStorageAdapter backed by
Arc<dyn object_store::ObjectStore> -- LocalFileSystem for local URIs,
the existing AmazonS3 build for s3://, plus a pub in_memory()
constructor (full contract including TRUE conditional updates; the
in-memory test backend testing.md asked for at the adapter level).
Why: the acknowledged-before-visible bug showed the two-impl shape has
no referee -- one prose contract, two independent answers. Upstream
LocalFileSystem::put_opts is byte-for-byte the staged-temp+rename/
hard_link idiom that fix converged on, and Lance's own commit protocol
is built on the same primitives (put-if-not-exists / rename-if-not-
exists), so the substrate-aligned move is to stop hand-rolling it.
The per-backend residue shrinks to a UriCodec (URI <-> object path)
and one capability flag.
Semantics preserved by construction, with three deliberate deltas:
- exists() is now object-store-semantics everywhere (head + non-empty
prefix fallback): an EMPTY local directory no longer 'exists'. The
only dir-shaped caller (_graph_commits.lance probes) self-heals via
ensure_commit_graph_initialized where it previously wedged loudly.
- A directory at an object path reads as NotFound, not as an IO error
('only objects exist'). The cluster unreadable-payload test used a
same-named directory as a portable non-NotFound trigger; it now uses
chmod 000, which still models genuine transient IO.
- write_text_if_match keeps content-token semantics on local
(PutMode::Update is NotImplemented upstream for LocalFileSystem in
0.12.5 and 0.13.2); the capability flag gates the token SOURCE in
read_text_versioned too -- an ETag token with content-compare writes
would lose every CAS.
delete_prefix keeps a local remove_dir_all branch: directories are a
local-FS concept, and list+delete would leave empty skeletons that
cluster graph_root_exists (raw Path::exists) reports as still present.
LocalStorageAdapter remains as a delegating shim so the pinned
contract tests gate this swap textually unchanged; the shim and the
test parameterization over local + in-memory land next. Cargo gains
the explicit 'fs' feature (already transitively enabled by lance).
* test(engine): one executable storage contract, run against every backend
Remove the LocalStorageAdapter delegation shim and migrate its
construction sites to ObjectStorageAdapter::local(). Replace the
per-backend duplicated tests with a single contract_suite asserting
the trait's promises (atomic replace, exists incl. the dataset-root
prefix probe, one-winner if_absent, versioned CAS with loud CAS-lost,
rename, list round-trip with no sibling-prefix bleed, idempotent
delete/delete_prefix), run against the local backend and the new
in-memory backend -- which implements true conditional updates, so the
strong-CAS path is exercised without a bucket. The bucket-gated S3
variant already exists (s3_adapter_conditional_writes_contract).
New local-specific pins for the deliberate semantic edges of the
collapse: empty directories are not objects (exists=false; the Lance
dataset-root probe shape is the non-empty case), file://-anchored and
spaces-in-path list output round-trips byte-identically into
read_text, dot-segment paths are lexically absolutized (the CLI's
./graph.omni shape), and upstream rename creating missing destination
parents. The acknowledged-write visibility regression test stays, now
documenting that the cross-API std::fs read-back is the point.
* refactor(cluster): drop put_json's per-backend atomicity branch
The local temp+rename dance predates the storage adapter guaranteeing
atomic visibility; now that write_text publishes via a staged temp +
rename on the filesystem (and a single atomic PUT on object stores) by
contract, the branch duplicated upstream behavior. One call, both
backends.
* docs: storage adapter collapse — contract, in-memory backend, local CAS gap
- testing.md: the 'no MemStorage backend' note is half-closed —
ObjectStorageAdapter::in_memory() covers the text-object layer with
the full contract (true conditional updates); Lance datasets bypass
the adapter, so the engine substrate ask stays open.
- invariants.md: truth-matrix Tests row updated; new Known Gap for
local write_text_if_match (upstream PutMode::Update is unimplemented
for LocalFileSystem; content-token emulation is safe only under the
cluster lock protocol — close before admitting a lock-free caller).
- writes.md: backend notes for the unified adapter (name#N staging
residue invisible to the sweep, backend-wrapped error text with
exists()-probing for missing-vs-error, loud permission failures).
* docs: finish renaming the storage adapters in user docs and test comments
storage.md's URI-scheme table and the S3 failpoint test's doc comment
still named the deleted LocalStorageAdapter/S3StorageAdapter; both now
describe the unified ObjectStorageAdapter over object_store, including
the relative-path absolutization note for local URIs.
* test(engine): pin branch-awareness of the drift guard's recovery advice
A pending sidecar on ANOTHER branch does not cover this branch's
drift: with a deferred feature-branch sidecar on disk and genuinely
uncovered drift on main, the main write's error must still point at
omnigraph repair -- a read-write reopen recovers the sidecar but
cannot repair main's uncovered drift. Currently red: the guard
matches sidecar pins by table_key only, so the feature sidecar flips
main's advice to the reopen path. Fix in the next commit.
Surfaced by external review of the drift-guard change.
* fix(engine): branch-aware sidecar matching in the drift guard's advice
The commit-time drift guard's sidecar-covered check matched pins by
table_key alone, so a pending sidecar on another branch flipped this
branch's uncovered-drift advice from 'run omnigraph repair' to the
reopen path -- and a reopen recovers that sidecar but cannot repair
this branch's drift. Compare the pin's table_branch too. Turns the
previous commit's red test green.
Surfaced by external review of the drift-guard change.
* test(engine): pin heal non-interference with a live schema apply
The write-entry heal's schema-staging reconcile runs before any queue
acquisition, so a load on the same handle, overlapping a schema apply
parked between its staging write and manifest commit, promotes the
apply's staging files (new catalog live against the old manifest),
classifies the LIVE apply's sidecar, and publishes its registrations
out from under it. The resumed apply then collides with its own stolen
commit. Currently red with:
Lance("Concurrent modification: table version 3 already exists for
node:Tag")
The fix (per-sidecar reconcile under the sidecar's write-queue guards,
plus a serialization key the schema-apply writer and the heal both
acquire) lands in the next commit.
Surfaced by external review of the write-entry heal.
* fix(engine): serialize the heal's schema-staging reconcile with live schema applies
The write-entry heal ran recover_schema_state_files up front, before
acquiring any queue guards. Overlapping a live schema apply parked
between its staging write and manifest commit, the heal promoted the
apply's staging files (new catalog live against the old manifest),
classified the LIVE apply's sidecar, and published its registrations —
the resumed apply then collided with its own stolen commit.
Correct by construction:
- New schema-apply serialization queue key, acquired by the schema-
apply writer (alongside its per-table keys) from before write_sidecar
until after delete_sidecar. Per-table keys alone don't cover a
registration-only migration, which pins no existing tables but has a
sidecar and staging files on disk.
- The heal reconciles schema staging lazily, PER SchemaApply sidecar,
after acquiring that sidecar's guards (including the serialization
key) and re-confirming the sidecar exists — a sidecar that survives
the queue wait belongs to a dead writer, so the reconcile can no
longer race a live apply. Recomputing per sidecar also removes the
staleness of one up-front result across a multi-sidecar pass.
- Omnigraph::refresh drops its up-front reconcile-and-pass-through
(same race, and a pre-promoted result would make the heal's guarded
reconcile see clean staging and wrongly defer the sidecar): it now
reconciles standalone only when NO sidecar exists — which cannot
race a live apply, whose sidecar always precedes its staging files —
and otherwise defers entirely to the heal.
The open-time sweep keeps its precomputed reconcile: open has no
concurrent writers. Turns the previous commit's red test green.
Surfaced by external review of the write-entry heal.
Self-audit addendum folded in: refresh's no-sidecar gate had a TOCTOU
(a live apply could write its sidecar + staging between the empty
check and the reconcile) — the standalone reconcile now holds the
serialization key across the list-then-reconcile pair. The remaining
residual is cross-process only (in-process queues cannot serialize
against a writer in another process; the open-time sweep has the same
pre-existing exposure) and is now an explicit Known Gap in
invariants.md rather than an implicit one.
* test(engine): pin catalog reload after the heal recovers a schema apply
When the write-entry heal rolls a crashed apply's SchemaApply sidecar
forward on the same handle, disk and manifest move to the new schema
(staging promoted, registrations published) but the handle's in-memory
schema_source/catalog do not. Subsequent writes then validate against
the stale catalog and reject rows of types the graph already has.
Currently red with:
record 1: unknown node type 'Tag'
refresh() reloads after its heal; the write entry points must too.
Fix in the next commit.
Surfaced by external review of the write-entry heal.
* fix(engine): reload the in-memory catalog after the heal recovers a schema apply
heal_pending_recovery_sidecars refreshed the coordinator and
invalidated the runtime cache after processing sidecars, but never
reloaded schema_source/catalog — so a write whose entry heal rolled a
crashed SchemaApply sidecar forward proceeded to validate against the
OLD schema while disk and manifest were already on the new one.
reload_schema_if_source_changed is the same post-heal step refresh()
already runs; it no-ops on the (overwhelmingly common) non-schema heal
because the on-disk source is unchanged. Turns the previous commit's
red test green.
Surfaced by external review of the write-entry heal.
* test(engine): pin that a deleted-branch sidecar cannot wedge the graph
A rollback-eligible sidecar pinned to a branch is deferred by every
roll-forward-only pass; if the branch is then deleted, the sidecar
survives, referencing a branch with no manifest tree. The heal (every
write entry) and the open-time sweep (every ReadWrite open) both fail
opening the dead branch, and repair refuses while a sidecar is pending
-- a terminal read-only state with manual sidecar surgery as the only
exit. Currently red with:
Lance("Not found: .../__manifest/tree/feature/_versions")
The branch's tree and forks are already reclaimed, so the pinned drift
is unreachable and the sidecar is provably moot; the fix classifies it
as an orphaned-branch terminal state (audit + discard) in both passes.
Surfaced by review (P1, verified by repro).
* fix(engine): classify deleted-branch sidecars as orphaned instead of wedging
A deferred (rollback-eligible) sidecar pinned to a branch survives
branch_delete; both the write-entry heal and the open-time sweep then
failed unconditionally opening the dead branch -- every write and
every ReadWrite open errored, and repair refuses while a sidecar
pends. Terminal state, manual sidecar surgery the only exit.
The branch's tree and per-table forks are already reclaimed at delete,
so the drift the sidecar pins is unreachable and the sidecar is
provably moot. Both passes now check the sidecar's branch against the
manifest's branch list (the authority -- deliberately NOT inferred
from a Not-found on open, which could be a transient storage error
masking real recovery intent) and discard orphans with an
OrphanedBranchDiscarded audit row, commit appended on main since the
sidecar's own branch no longer has a commit graph.
The open-time half is pre-existing; the write-entry heal made it hot.
Turns the previous commit's red test green.
Surfaced by review (P1, verified by repro).
* chore: harden review nits — vacuous CI filter, root-runner skip, liveness note
- ci.yml: the RustFS sidecar-lifecycle step now fails loudly if the
's3_' name filter matches zero tests (cargo passes vacuously on an
empty filter; the step exists specifically to prove S3 sidecar I/O
coverage). The pre-existing CLI smoke step has the same shape and is
left for a follow-up.
- cluster unreadable-payload test: cfg(unix) + a skip-with-log when
running as root (mode 000 is still readable to root, common in
container dev runners), so the test degrades instead of failing.
- refresh: document the one-pass-late convergence for legacy staging
residue while non-SchemaApply sidecars pend, so nobody 'fixes' it by
re-running the reconcile unserialized — the exact race the
serialization key closes.
* test(engine): pin orphan-discard idempotency across a delete fault
discard_orphaned_branch_sidecar writes its audit row and main commit
before deleting the sidecar; a Phase D delete fault leaves the sidecar
on disk with the audit already durable, and the retry repeated the
whole path -- a second OrphanedBranchDiscarded audit row (and commit)
for the same operation. Currently red: 2 rows after one fault + retry.
The retry must only finish the delete. Fix next.
Also promotes the recovery-audit kinds reader into the shared test
helpers (it was recovery.rs-local).
Surfaced by external review of the orphan-discard fix.
* fix(engine): orphan-discard idempotency + heal reports acted-vs-deferred
Two review findings on the recovery surface:
- discard_orphaned_branch_sidecar now checks the audit table for an
existing (operation_id, OrphanedBranchDiscarded) row before appending
the commit + audit pair, so a Phase D delete fault retries ONLY the
delete instead of duplicating audit rows and commit-graph entries.
Cold path: the list scan runs only when an orphaned sidecar exists.
Turns the previous commit's red test green (exactly one audit row
across fault + retry).
- process_sidecar returns whether durable state changed; the heal sets
processed_any only for sidecars that were actually rolled forward /
rolled back / audit-recovered (orphan discards count). Deferred
sidecars (rollback-eligible, invariant-violating, unpromoted
SchemaApply) no longer trigger a per-write schema reload + full
runtime-cache invalidation while they pend -- the cache is
snapshot-keyed so this was waste, not corruption, but it was paid on
every write until reopen. Acted-paths' processed=true remains pinned
by load_after_schema_apply_phase_b_failure_uses_recovered_catalog
(the reload depends on it).
Surfaced by external review.
* test(engine): pin the orphan-discard audit-append fault leg as documented tolerance
The orphan discard's commit append and audit append are two writes; a
failure between them leaves a recovery commit with no audit row, and
the retry (keyed on the audit row, the operator-facing record) appends
a second commit before the audit lands. This is the same
not-atomic-pair-write tolerance record_audit documents and the
manifest->commit-graph Known Gap covers for every publish: bounded
commit-graph noise, audit row exactly-once under clean failures.
Keying idempotency on commit rows instead would need an operation_id
column on _graph_commits, and audit-before-commit would dangle the
graph_commit_id join -- both worse than the documented residual.
Make the tolerance explicit instead of implicit: docstring names the
window, a failpoint sits inside it, and the new test pins convergence
across the fault (sidecar consumed, exactly one audit row), completing
the orphan-discard fault matrix alongside the delete-fault leg.
Surfaced by external review of the orphan-discard idempotency.
* test(engine): pin honest drift-guard advice when sidecar listing fails
The guard's unwrap_or(false) conflated 'classified as uncovered' with
'could not classify': a transient list fault on the guard's second
list (the entry heal's first list having succeeded) confidently routed
the operator to omnigraph repair even when the heal had just deferred
a rollback-eligible sidecar -- and repair refuses while a sidecar is
pending. Currently red: the error says 'run omnigraph repair' with no
mention of the reopen path. The fix names both paths plus the failure
cause when classification is impossible.
Surfaced by external review of the drift-guard fallback.
* fix(engine): admit ambiguity in the drift guard when sidecar listing fails
Replace the unwrap_or(false) fallback with a tri-state: covered ->
reopen advice; uncovered -> repair advice; listing FAILED -> say the
drift could not be classified, name the cause, and give both paths in
order ('run repair, or reopen read-write if repair reports a pending
sidecar'). The old fallback confidently routed a transient list fault
to repair, which refuses while a sidecar is pending -- a self-
correcting but pointless detour. The conflict itself is still always
raised; only the advice degrades honestly. Turns the previous commit's
red test green.
Surfaced by external review of the drift-guard fallback.

exec/query: structured Expr pushdown via Scanner::filter_expr (unblocks CompOp::Contains) (#113)
* exec/query: pushdown IR filters via DataFusion Expr (Scanner::filter_expr) Switches `execute_node_scan` from string-flattened Lance SQL pushdown (`build_lance_filter` + `scanner.filter(&str)`) to structured DataFusion Expr pushdown (`build_lance_filter_expr` + `scanner.filter_expr(Expr)`). ## What this enables 1. **`CompOp::Contains` now pushes down.** `ir_filter_to_sql` returned `None` for list-contains (the comment said *"Can't pushdown list contains"*) because string SQL can't easily express it. With Expr, it lowers to DataFusion's `array_has(col, value)` builtin via the `nested_expressions` feature, and pushes down to Lance's scan layer the same way Eq/Lt/etc. do. Pinned by the new regression test `end_to_end::ir_filter_with_list_contains_pushes_down`. 2. **DataFusion 53's optimizer rules now reach our predicates.** Once the Expr lands at the Lance scanner, DF's planner runs: - `IN`-list vectorized eq kernel (DF #20528) - `PhysicalExprSimplifier` (DF #20111) - CASE WHEN x THEN y ELSE NULL shortcut (DF #20097) - Push limit into hash join (DF #20228) None of these were applicable before because the string SQL path short-circuited the optimizer. ## Scope This is one of three string-flattened pushdown sites; the other two (`hydrate_nodes`/Expand pushdown at query.rs:771-796 and the mutation delete path in `exec/mutation.rs::predicate_to_sql`) stay on the SQL string path for now: - The Expand pushdown still serializes through `hydrate_nodes`'s `extra_filter_sql: Option<&str>` parameter. Migrating it changes the `TableStorage` trait surface (`scan_stream(filter: Option<&str>)` → `Option<Expr>`) and the cascading call sites — out of scope for this MR. - The mutation delete predicate still goes through `Dataset::delete(&str)` in Lance 6.0.1. MR-A (delete two-phase via Lance #6658, gated on the Lance v7 bump per issue #112) will migrate that path to `DeleteBuilder::execute_uncommitted` taking an Expr. The existing `ir_filter_to_sql` / `ir_expr_to_sql` / `literal_to_sql` helpers stay in place to serve the remaining string-SQL consumers (mutation predicates). They get retired when the other call sites migrate. ## Cargo Enables the `nested_expressions` feature on the `datafusion` workspace dep. Lance already pulls in `datafusion-functions-nested` transitively (it's listed in their feature set), so this just exposes the `datafusion::functions_nested::expr_fn::array_has` re-export. No transitive dep change (Cargo.lock unchanged). ## Tests - New: `ir_filter_with_list_contains_pushes_down` — pins the case that was previously impossible (`ir_filter_to_sql` returning `None`). - 906/906 workspace tests still pass. - 417/417 engine integration tests pass (was 416 + the new one). - 19/19 failpoints (recovery canary). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * ci: pin rustfs/rustfs to 1.0.0-beta.3 (last known-good before creds-policy break) The RustFS S3 Integration job started failing 2026-05-23 with all 3 tests panicking on the first PUT: HTTP error: error sending request The "Dump RustFS logs on failure" step revealed the container was dying at startup: [FATAL] Server encountered an error and is shutting down: Default root credentials are not allowed on non-loopback listeners; set RUSTFS_ACCESS_KEY and RUSTFS_SECRET_KEY to non-default values, bind to loopback, or set RUSTFS_ALLOW_INSECURE_DEFAULT_CREDENTIALS=true for local development only `rustfs/rustfs:latest` was updated 2026-05-21 (1.0.0-beta.4) with a credentials-policy check that rejects `rustfsadmin`/`rustfsadmin` as "default" values. PR #111 passed yesterday because it ran against beta.3; today's runs against beta.4 fail at container startup. This is unrelated to PR #113's Expr-pushdown refactor — the bump just happened to hit the same week. Pin to 1.0.0-beta.3 (2026-05-14, last tag before the change). The right long-term fix is one of: - Rotate the CI creds to less-default values (less coupling to RustFS's "default" set definition) - Set `RUSTFS_ALLOW_INSECURE_DEFAULT_CREDENTIALS=true` per the error message - Use a workflow service container with controlled lifecycle Deferred — pinning is the minimal restore. Also incidentally documents *which* version we tested against, which `:latest` never did.

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).

policy: chassis core — omnigraph-policy crate + Omnigraph::enforce() (MR-722) (#102)
PR #2 of the policy chassis series (PR #1 = MR-731, merged in #101). The structural fix that moves Cedar enforcement from HTTP-only to engine-wide. apply_schema is the proof-of-concept writer; PR #3 fans the enforce() call out to the remaining six (mutate_as, load, ingest_as, branch_create_from, branch_delete, branch_merge). ## What lands ### New crate: omnigraph-policy The 844-line policy.rs moves from `omnigraph-server` into a new `omnigraph-policy` workspace crate so both engine and server can depend on it. Cedar dependency moves with it. The server's policy.rs becomes a re-export shim (`pub use omnigraph_policy::*`) so existing `omnigraph_server::PolicyAction` etc. paths keep working — CLI and test consumers don't have to migrate in one go. ### New trait: PolicyChecker ```rust pub trait PolicyChecker: Send + Sync { fn check(&self, action: PolicyAction, scope: &ResourceScope, actor: &str) -> Result<(), PolicyError>; } ``` `PolicyEngine` (Cedar-backed) implements it. `Omnigraph::with_policy()` takes `Arc<dyn PolicyChecker>`. Engine tests mock the trait without spinning up Cedar. MR-725 will extend the trait with `predicate_for()` for query-layer pushdown — additive, no call-site changes. ### New enum: ResourceScope Four variants — Graph, Branch, TargetBranch, BranchTransition — mapping cleanly to today's `(branch, target_branch)` shape on PolicyRequest via `to_branch_pair()`. Each engine writer picks the variant that matches the existing HTTP-layer convention so engine and HTTP evaluate the same Cedar decision. **Invariant**: ResourceScope stays at branch granularity. Per-type and per-row scope are MR-725's territory, not engine-layer's. Adding Type/Row variants here creates two places per-type policy can be evaluated, which can drift. See chassis design refinements comment on MR-722 (2026-05-17). ### Omnigraph::with_policy() + enforce() * New `policy: Option<Arc<dyn PolicyChecker>>` field on Omnigraph, None by default (preserves embedded/dev no-enforcement mode). * `with_policy(self, checker)` setter — builder-style, consumes self. * `enforce(action, scope, actor)` — the gate. When policy is None, no-op. When policy is Some AND actor is None, hard error — silent bypass via "I forgot the actor" is exactly the footgun this gate is here to prevent. ### apply_schema_as: first writer wired * New public method `apply_schema_as(source, options, actor)` that calls `enforce(SchemaApply, TargetBranch("main"), actor)` before acquiring the schema-apply lock or doing any other work. * Existing `apply_schema(source)` and `apply_schema_with_options(...)` delegate to it with actor=None (no-actor variants). * HTTP handler `server_schema_apply` updated to call apply_schema_as with the resolved actor. AppState construction injects the PolicyEngine into Omnigraph via `with_policy`. HTTP-layer authorize_request still fires first; the engine gate is the redundant-but-correct backstop and the only path that protects SDK / embedded callers. PR #3 removes the HTTP redundancy. ### OmniError::Policy New error variant for engine-layer policy denial / evaluation failure. ApiError::from_omni maps it to 403. ### MR-724 Admin action — Option A reservation PolicyAction::Admin kept in the enum with a load-bearing doc comment naming its future consumers (hot reload, audit log query, approvals list per MR-726 / MR-732 / MR-734). No enforce(Admin, ...) call site exists yet — the variant is reserved so the action vocabulary is complete from chassis day one. MR-724 closes when the first consumer surface ships. ### New SDK-side integration test `crates/omnigraph/tests/policy_engine_chassis.rs` — four tests covering: * Policy denies for unauthorized actor → OmniError::Policy * Policy permits for authorized actor → apply succeeds * Policy installed + no actor → hard error (forget-the-actor footgun) * No policy → no-op (embedded/dev default still works) These exercise the engine path directly — no HTTP layer involved. ## Test results - cargo test --workspace --locked --no-fail-fast: 851 passed, 0 failed * 45 server tests (existing) pass * 14 schema_apply tests (existing) pass * 4 new chassis tests pass * 60 OpenAPI tests pass (no HTTP API surface changes) * No regressions across the workspace ## Architectural decisions baked in Per MR-722 chassis design refinements comment (2026-05-17): 1. PolicyChecker is a trait, not just a concrete. Engine and server consume the trait. MR-725 adds predicate_for() additively. 2. ResourceScope stays at branch granularity. No Type/Row variants. 3. Coarse-vs-fine framing pinned: engine-layer is action gate; query-layer (MR-725) is predicate gate. Both backed by same Cedar engine; non-overlapping responsibilities. 4. Admin action reserved for policy-management surfaces (MR-724 Option A). ## Pending follow-ups (PR #3+) - Fan-out enforce() to mutate_as, load, ingest_as, branch_create_from, branch_delete, branch_merge (PR #3). - Remove HTTP-layer authorize_request redundancy once engine gate covers all writers (PR #3). - CLI policy injection into Omnigraph for non-`policy validate|test|explain` subcommands (PR #3 or follow-up). - MR-723 default-deny 3-state matrix (PR #4). - MR-736 severity warn/deny (PR #5). - AGENTS.md scope-of-enforcement rewrite once chassis fully lands. - Coarse-vs-fine framing in docs/user/policy.md. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> |

MR-794 step 2: scaffold MutationStaging accumulator + scan_with_pending
Add the scaffolding for the in-memory staged-write rewire — no behavior change yet: * New crates/omnigraph/src/exec/staging.rs with MutationStaging, PendingTable, PendingMode, StagedTablePath, plus the end-of-query finalize() that issues one stage_* + commit_staged per pending table (Merge mode dedupes by id, last-write-wins). * TableStore::scan_with_pending and count_rows_with_pending helpers — Lance scan committed + DataFusion MemTable scan pending, concat. Sidesteps the Scanner::with_fragments filter-pushdown limitation documented on scan_with_staged. * Add datafusion = "52" to workspace + omnigraph-engine deps for MemTable (transitively pulled by Lance already). Engine code still uses the legacy MutationStaging shape; the rewire lands in subsequent commits. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Parallel per-type load writes + omnigraph optimize/cleanup CLI (#46)
* Parallel per-type load writes + omnigraph optimize/cleanup CLI
## MR-677.3 — parallel per-type load writes
The load path already groups records into one RecordBatch per type and
makes one Lance commit per table (loader::mod.rs:249-..), but those
commits ran sequentially. Wrap node and edge write loops in
`futures::stream::buffered(N)` against a new helper
`write_batches_concurrently`. Concurrency tunable via
`OMNIGRAPH_LOAD_CONCURRENCY` (default 8).
## MR-676 — `omnigraph optimize` and `omnigraph cleanup`
New CLI subcommands that walk every node + edge table in the repo:
- `omnigraph optimize <uri>` — runs Lance `compact_files` on each
table to merge small fragments into fewer larger ones.
- `omnigraph cleanup <uri> --keep N | --older-than 7d --confirm` —
runs Lance `cleanup_old_versions` to prune historical manifests +
unique fragments. Requires `--confirm` because it's destructive.
Supports both count-based and time-based retention (or both AND'd
together). Time uses chrono `DateTime<Utc>` (added as a workspace
dep, default-features off).
Both commands run their per-table loops in parallel (8-way bounded,
`OMNIGRAPH_MAINTENANCE_CONCURRENCY` env override). Smoke-tested
against the 114-table prod graph: optimize went 7m15s sequential
→ 1m28s parallel. cleanup --keep 1 removed 137 historical versions
across 114 tables in 1m57s without disrupting `/healthz` or query
responses.
Public API on `Omnigraph`:
pub async fn optimize(&mut self) -> Result<Vec<TableOptimizeStats>>
pub async fn cleanup(&mut self, opts: CleanupPolicyOptions)
-> Result<Vec<TableCleanupStats>>
All 10 existing loader tests still pass.
Closes MR-676.
Partially addresses MR-677 (the .3 — parallel by type — piece;
MR-677.1 is for the `omnigraph embed` path, not load, since load
doesn't call Gemini directly. .2 was already in place).

Harden bearer auth: constant-time compare, hashed at rest, authoritative actor_id
Fixes two live authz bugs in omnigraph-server: - Bearer-token lookup previously used HashMap::get, which compares keys with Eq and short-circuits on the first differing byte — a network-observable timing oracle for brute-forcing tokens. Tokens are now stored as SHA-256 digests and compared with subtle::ConstantTimeEq, iterating every entry unconditionally so total work is independent of which slot matches. Raw token bytes no longer live in server memory after startup. - authorize_request now overwrites PolicyRequest.actor_id from the authenticated session instead of trusting the handler-supplied field, which previously defaulted to "" via unwrap_or_default(). The empty string can no longer reach Cedar as a policy subject even if a future refactor drops the None check. External API of AppState constructors is unchanged — tokens still enter as Vec<(String, String)> and are hashed on the way in. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Integrate utoipa 5 to auto-generate an OpenAPI 3.1 spec from the existing Axum handlers and serde types. All 16 endpoints are annotated with path metadata, request/response schemas, security requirements, and tags. A public /openapi.json endpoint serves the spec without requiring auth. Includes 59 tests covering path completeness, HTTP methods, schema fields, enum variants, security scheme, path/query parameters, request bodies, response references, and endpoint integration. https://claude.ai/code/session_01NfoPVx21rZUQned1f7WpXY |
