d8354ac213 test(cli): address review — assert schema-show success, document exit-code stance, add e2e opt-out
- The drift-heal verification now asserts `schema show` succeeded and
  produced a schema before checking the rogue field's absence (a failed
  command previously made the negative assertion vacuously pass).
- cluster_cli documents why it deliberately does not assert exit codes
  (blocked applies exit non-zero by contract while emitting the structured
  output callers assert on).
- The comprehensive lifecycle e2es honor OMNIGRAPH_SKIP_SYSTEM_E2E=1
  (graceful skip-with-message, the S3-gate pattern) for constrained
  sandboxes; requirements + suppression documented in testing.md.

7d70811df1 test(cli): comprehensive full-cycle cluster e2e with a live server
Two system tests composing the whole Phase 1-5 surface with real binaries:

- local_cluster_full_lifecycle_declare_serve_evolve_delete: declare two
  graphs -> one apply creates and converges them -> the --cluster server
  serves both stored queries -> schema+query evolve in one apply (migration
  previewed in plan) -> restart serves the new shape -> out-of-band schema
  drift observed by refresh and converged back by apply (rogue field
  soft-dropped) -> approved graph delete -> restart serves the survivor and
  404s the tombstoned graph -> final plan empty. Catches composition
  regressions where each stage passes its own tests but the lifecycle
  breaks (the composite_flow.rs principle at the control-plane level).

- local_cluster_serving_enforces_applied_policy_bindings: applied policy
  bundles gate serving per their bindings over HTTP with bearer-resolved
  actors — the cluster-bound bundle owns graph_list (admin 200, reader 403,
  anonymous 401), the graph-bound bundle owns invoke_query (reader gets
  rows; denied invocation is the documented anti-probing 404).

711865e6f1 docs(cluster,server): the Phase 5 mode switch; retire applied-not-serving caveats
The standing caveat ('applied means recorded in the cluster catalog —
nothing more; the server still boots from omnigraph.yaml') retires: cluster
docs gain the 'Serving from the cluster' section (exclusivity, applied-
revision serving, fail-fast readiness, restart-to-pick-up, expose-all
bridge), server.md gains mode-inference rule 0 and the cluster-booted multi
mode, deployment.md the boot-source choice, and the CLI's apply note plus
the cli-reference cluster row (stale back to Stage 3A) now describe the full
convergence surface. RFC-005 flips to Landed with four implementation
deviations recorded.

f3eb60fa4e test(cli): applied-means-serving system e2e
The Phase-5 contract end to end with real binaries: cluster import + apply
via the CLI, seed a row through the graph plane, boot omnigraph-server with
--cluster (no omnigraph.yaml anywhere), and the applied stored query serves
the row over HTTP through the multi-graph routes.

948a54daa7 feat(server): boot from cluster state via --cluster
RFC-005 §D1/§D2: omnigraph-server --cluster <dir> is rule 0 of the mode
inference — an exclusive boot source (hard error when combined with a graph
URI, --target, or --config) that never opens omnigraph.yaml, not even the
implicit current-directory search. The cluster branch reads the applied
revision through omnigraph-cluster's serving-snapshot API and feeds the
EXISTING multi-graph pipeline: GraphStartupConfig per recorded graph at its
derived root, stored queries built via QueryRegistry::from_specs from
verified blob content (expose-all — the §D5 bridge until Phase 6
policy-owned exposure), cluster-bound policy bundles as the server-level
Cedar engine and graph-bound bundles per graph, straight from the
content-addressed blob paths. Multiple bundles binding one scope refuse boot
(one-bundle-per-scope is the serving pipeline's shape; stacking is a later
slice). Everything downstream — parallel opens, query type-checking,
registry, routing, auth, OpenAPI — is reused unchanged; cluster mode is a
new source, not a new pipeline.

First server->cluster crate dependency: read-only types + one fn;
omnigraph-cluster stays HTTP-free. open_multi_graph_state goes pub for
integration tests.

f5b43164b8 feat(cluster): pub read-only serving-snapshot API
RFC-005 §D2/§D4: read_serving_snapshot reads the applied revision as
everything a server needs to boot — graphs at derived roots, stored-query
sources read from the content-addressed catalog and re-hashed against the
recorded digests, policy blob paths with their applied applies_to bindings.
All-or-nothing: missing state, pending recovery sidecars, missing/tampered
blobs, pre-5A entries without bindings, and an empty graph set each refuse
the snapshot with a remedy; no partial serving. Lock-free by design — the
state file is replaced atomically, so the read is a consistent
point-in-time ledger.

0b84b1adc3 feat(cluster): record policy applies_to bindings in the applied revision
Slice 5A of RFC-005: the state ledger becomes serving-sufficient for the
Phase-5 server boot. StateResource gains an optional applies_to (normalized
typed refs: cluster | graph.<id>), written by apply for every applied policy
create/update from the desired config's validated bindings.

The hole this closes: applies_to is not part of the policy file digest, so a
binding-only edit previously produced NO plan change at all (a 4C e2e even
asserted that — the gap, not a contract). Binding changes are now
first-class: a post-diff pass emits an Update with equal before/after
digests and a binding_change marker (visible in plan/apply JSON and human
output as [bindings]), classification/execution treat it as an ordinary
catalog-tier applied change (payload skips naturally — the blob is
unchanged), and convergence requires zero binding divergence, so stale
bindings can never report converged. Pre-5A ledger entries (no bindings
recorded) surface as the same backfill Update; one apply heals them, exactly
the remedy RFC-005's boot-error path names.

87691fe9c7 test(cluster): failpoint coverage for delete crash windows
- Crash before the removal: root intact, approval file unconsumed, sidecar
  survives, no ack; the next run retires the stale intent (row 8) and the
  still-approved delete completes in the same run.
- Crash after the removal, before the state CAS: root gone, ledger
  byte-identical, the sidecar carries the approval id; the next run's sweep
  rolls the tombstone forward, consumes the approval, audits the recovery,
  and converges (row 7b).

d1d04217ab feat(cluster): execute approved graph deletes in cluster apply
Stage 4C execution half (RFC-004 §D5/§D6 + sweep rows 7/7b/8): an approved
graph.<id> delete — and its riding schema/query deletes — classifies Applied
and executes LAST in the run, sidecar-fenced: pre-op manifest pin (best
effort; partial roots still delete), approval_id carried in the sidecar,
recursive root removal (NotFound tolerated), subtree tombstoned out of the
ledger with a tombstone observation, the approval consumed in the same state
CAS (ledger summary) and its artifact file rewritten with consumed_at only
after the CAS lands — a failed run consumes nothing and the approval stays
valid for the retry.

Sweep rows: already-tombstoned intents retire (7); a completed delete with a
stale ledger rolls forward — tombstone + approval consumption + audit entry
(7b, idempotent); a still-present root retires the stale intent with a
graph_delete_incomplete warning and the still-approved delete re-executes in
the same run (8) — prefix removal is idempotent, so retry IS the repair.

The multi-graph mixed e2e gets its conclusion: blocked without approval,
cluster approve graph.engineering --as andrew, converge, tombstone visible
in status. Phase 4's disposition matrix is now fully executable.

f4e9105272 feat(cluster): cluster approve — digest-bound approval artifacts
RFC-004 §D4, gate half: graph deletes (and their subtree) now classify
Blocked/approval_required instead of Deferred; the new cluster approve
command (requires the global --as actor) writes
__cluster/approvals/{ulid}.json bound to the desired config digest and the
change's before/after digests, so config or state drift invalidates the
artifact automatically (approval_stale warning, never authorizes). One gate
per subtree: compute_approvals lists only the graph-level delete, and
ApprovalRequirement gains a satisfied flag surfaced by plan. Consumption and
the delete executor land next — until then approved deletes stay blocked so
a gate-only build can never strip state without removing the root.

- Crash before the engine call: sidecar (carrying the --as actor) survives,
  live schema and ledger untouched, no ack; the next run's sweep retires the
  stale intent and the same run applies and converges.
- Crash after the engine call, before the state CAS: the manifest moved with
  the post-op pin in the sidecar, state.json byte-identical; the next run's
  sweep rolls the ledger forward with a schema_apply audit entry and the run
  converges.

a1ba4dc413 feat(cluster): execute schema applies in cluster apply
Stage 4B (RFC-004 §D1/§D5): schema.<id> Update changes classify Applied and
execute after graph creates, sequentially and sidecar-fenced — read-write
open (the engine's own recovery runs first), pre-op manifest pin recorded,
apply_schema_as with allow_data_loss: false (soft drops only; hard drops wait
for 4C's approval artifacts), post-op pin rewritten into the sidecar, sidecar
retired only after the final state CAS. Queries gated on a same-plan schema
update unblock (the migration lands first in the same run); failures —
unsupported migrations, lock contention, user branches — surface as
schema_apply_failed with the engine's message, demote dependents via the
origin-aware demotion helper, and stop further graph-moving work.

Schema evolution is now fully cluster-driven (the defer -> manual schema
apply -> refresh loop is gone), and out-of-band schema drift is converged
back by apply as an ordinary soft migration (axiom 8: drift correction is
gated like any change; the recoverable tier needs no approval) — both pinned
by reworked e2es. The multi-graph mixed e2e's deferred row is now
delete-shaped, pre-staging the 4C surface.

Actor: cluster apply accepts the CLI's global --as via the new ApplyOptions /
apply_config_dir_with_options (apply_config_dir delegates unchanged); the
actor is echoed in ApplyOutput and recorded in sidecars and audit entries,
and threads to apply_schema_as so Cedar fires wherever a checker is
installed.

ca63a9340b feat(cluster): embed schema migration previews in cluster plan
RFC-004 §D7's data-aware preview: for every schema update, plan opens the
live graph read-only and embeds the engine's migration plan (supported flag
+ typed steps) in the change record; the human renderer prints the steps.
Preview failures (unreachable graph, planner error) degrade to the digest
diff with a schema_preview_unavailable warning — planning never blocks.

c3007369cd feat(cluster): execute graph creates in cluster apply
Stage 4A (RFC-004 §D1/§D5): graph.<id> Create — and its paired schema Create,
which the init carries — classify Applied and execute first in the run,
sequentially and sidecar-fenced: sidecar written before Omnigraph::init at
the derived root, rewritten with the post-init manifest pin, deleted only
after the final state CAS lands. Dependent queries and policies no longer
block on a graph create in the same plan — creates run first, so they apply
in the same run; a create failure demotes them to blocked
(dependency_not_applied) and stops further graph-moving work (loud partials),
with the sidecar left for the sweep to classify. Graphs with a kept recovery
sidecar (rows 5/6) classify Blocked/cluster_recovery_pending, and the sweep's
Drifted/Error statuses are never clobbered by a generic Blocked.

Schema source is re-read and digest-verified under the lock before the init
(the write_resource_payload TOCTOU posture). Plan previews the same
dispositions. e2e fallout updated: a fresh multi-graph config now converges
in one apply; a destroyed root is re-created as an EMPTY graph by the next
apply (declarative convergence — visible in plan, called out in docs); the
new cluster_e2e_declared_graph_created_by_apply pins the no-manual-init flow.

bf8cc7a753 feat(cluster): graph-create recovery sidecars and sweep
RFC-004 §D2/§D3 for the graph_create kind. RecoverySidecar records intent
under __cluster/recoveries/{ulid}.json; the roll-forward-only sweep runs at
the start of apply/refresh/import under the state lock and classifies each
survivor by observation: root absent -> intent removed (row 1); outcome
already recorded -> retired (row 2); create completed but state stale ->
ledger rolled forward with a recovery_records audit entry (row 4); partial
root -> Error/graph_create_incomplete, kept, never auto-deleted (row 5);
unexpected schema -> Drifted/actual_applied_state_pending, kept (row 6).
Sweep mutations ride the command's existing CAS write; completed sidecars
are deleted only after that write lands. Read-only status/plan warn
(cluster_recovery_pending) without acting. The apply payload gate now counts
only payload-phase errors so kept-sidecar diagnostics don't abort the run
before their statuses persist.

211b37e6de test(cluster): failpoint tests for crash-mid-apply and state CAS race
The apply-side coverage the implementation spec's hard gate requires before
Phase 4 graph-moving apply:

- crash after the payload phase: state.json byte-identical, blobs inert on
  disk, lock released, no phantom statuses, nothing acknowledged; a plain
  re-run repairs via skip-if-exists blob reuse.
- CAS race: a cfg_callback rewrites state.json at the exact read->write
  window (the state.lock:false concurrent-writer scenario); apply surfaces
  state_cas_mismatch, acknowledges nothing, reports the persisted status
  snapshot, leaves the concurrent writer's state on disk; a re-run converges.

CI's failpoints step now runs both the engine and cluster suites.

Diagnostic-typed injected errors, and two call sites in apply_config_dir:
cluster_apply.after_payload_phase (the crash point: blobs on disk, state
untouched) and cluster_apply.before_state_write (routes through the
persisted-statuses revert contract; a cfg_callback here can mutate state.json
to make the CAS check fail organically). Feature off compiles to Ok(()) —
zero behavior change. Tests live in a separate integration binary because the
fail registry is process-global. Also refresh the crate description (stale
'read-only' since Stage 3A).

15868972ff feat(cluster): verify catalog payload blobs in status and refresh
Closes the Stage 3A product gap where a deleted or corrupted blob under
__cluster/resources/ went unnoticed forever (status reported converged and
apply could not repair it because the digests matched).

verify_catalog_payloads checks every query/policy digest in state against its
content-addressed blob (existence + full sha256 re-hash; graph/schema/unknown
addresses have no payloads and are skipped). status reports findings read-only
(warnings catalog_payload_missing/_mismatch; error catalog_payload_read_error
— an unverifiable catalog must not report healthy). refresh closes the
self-heal loop: missing/mismatched blobs mark the resource drifted and remove
its digest from state so the next plan proposes a create and the next apply
republishes; unreadable blobs keep the digest (no spurious republish), mark
error, and exit non-zero. Verification runs before graph observation so the
recomputed graph composite already excludes removed query digests.

test(cli): cluster e2e hardening — lost-state recovery, out-of-band drift, root destruction, multi-graph convergence (#166)
Four lifecycle compositions over the spawned binary that pin spec claims no
single-command test proves:

- Lost ledger: delete state.json -> re-import from the live graph -> re-apply
  converges onto the same content-addressed blobs (axiom 5's reconstructable-
  state resilience edge, end to end).
- Out-of-band schema apply (the Sarah/Bob violation): refresh marks
  graph/schema Drifted with schema_mismatch, status and plan surface it, and
  cluster apply refuses to silently correct it — state keeps the LIVE schema
  digest (drift correction is gated, axiom 8).
- Destroyed graph root: refresh records graph_missing drift and drops
  graph/schema digests while preserving query/policy; plan proposes deferred
  creates only; apply moves nothing and the catalog stays intact.
- Two graphs (one live, one not yet created) + a graph-spanning policy + a
  cluster-scoped policy: a single apply yields all four dispositions at once
  (applied/derived/deferred/blocked, deterministically ordered), then the
  second graph appears, refresh observes it, and apply converges.

Helpers: init_named_cluster_graph generalizes init_cluster_derived_graph;
write_multi_graph_cluster_fixture builds the two-graph config.

5e1dede08f fix(cluster,cli): apply failure output — persisted statuses only, changes list printed
Two review findings (greptile, PR #165):

- ApplyOutput.resource_statuses on a failed state write now carries the
  pre-apply on-disk snapshot instead of the in-memory mutations that were
  never persisted, so automation reading the field independently of `ok`
  cannot see phantom applied/blocked statuses. Regression test forces the
  state write to fail via a read-only __cluster dir (unix-only, skips when
  permissions are not enforced).
- Human-mode `cluster apply` prints the classified changes list on failure
  too, so an operator debugging a partial apply without --json sees what was
  attempted.

(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: 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

d870eaaf3f test(cli): cluster lifecycle e2e — real-graph import/apply/refresh, schema-change loop, force-unlock retry
Three composition tests over the spawned binary against a real derived graph:

- import -> plan (dispositions) -> apply -> status -> refresh -> plan-empty,
  then a query edit round-trip. Pins that refresh and apply recompute the
  graph composite digest identically — divergence would silently re-open
  the plan forever and no single-command test would catch it.
- The Stage 3A operator workflow across the control/data-plane boundary:
  cluster apply defers a schema change, omnigraph schema apply executes it,
  cluster refresh observes it, the next cluster apply re-converges.
- Held lock refuses apply, force-unlock clears it, retried apply converges.

bcef8444dd feat(cli): omnigraph cluster apply
Terraform-style: apply executes directly (cluster plan is the preview, now
annotated with apply dispositions). Human output prints per-change
dispositions, convergence, and the catalog-only caveat; --json emits the full
ApplyOutput. Exit is non-zero only on errors — deferred/blocked changes are
warnings with converged: false as the automation signal.

1f8e5945cf feat(cluster): config-only apply with content-addressed catalog publish
apply_config_dir executes the query/policy subset of the plan: payloads are
written content-addressed under __cluster/resources/{query,policy}/... before
the state CAS (state is the publish point; orphaned blobs from a failed CAS
are inert and re-apply is the repair), then state.json is CAS-updated with
applied digests, Applied/Blocked statuses, and a revision bump. Graph/schema
changes are never executed here: schema content and graph lifecycle defer to
a later phase with loud warnings, while graph.<id> composite-digest updates
whose schema component is unchanged converge automatically via recomputation
from state's own components (without which apply could never converge).
Idempotent re-apply leaves state bytes and revision untouched.

PlanChange gains optional disposition/reason fields, populated by the same
classifier in cluster plan, so plan is an honest preview of what apply will
execute, derive, defer, or block.

fix(unique): collision-free tuple key shared by intake and merge, loud on un-keyable types (#160)
* fix(unique): collision-free tuple key shared by intake and merge, loud on un-keyable types

Hardening on top of #133. That PR introduced a shared
`loader::composite_unique_key(parts)` joining per-column scalars with U+001F
and routed both intake and branch-merge through it, closing the original
'|' vs U+001F separator drift. This takes the shared keying the rest of the
way to correct-by-design:

- Collision-free by construction: the key is now the tuple of per-column
  scalar strings (Vec<String>) keyed directly, no separator, so no data value
  (not even a literal U+001F) can forge a collision.
- One scalar converter across both paths: intake used an explicit type-match,
  merge used Arrow's array_value_to_string. Both now derive the key through
  composite_unique_key(group_columns, row), so they can't drift on conversion.
- Loud on un-keyable types: the scalar converter returned None for any Arrow
  type it didn't recognize, and the caller treated None as null-exempt, so a
  @unique on a column type it couldn't reduce (list, blob) was silently
  un-enforced. It now returns Err, surfacing the constraint it can't enforce
  instead of weakening it in silence.

Tests:
- consistency::composite_unique_key_is_consistent_across_intake_and_merge pins
  that intake and merge key the tuple identically (load-on-branch then merge
  of values containing '|').
- loader unit tests pin tuple keying + null exemption and the loud error on an
  un-keyable (binary) column.

Docs: invariants truth-matrix updated; stale loader/mod.rs line pointers fixed.
Scope unchanged: intra-batch / merge-candidate-set only; cross-version
uniqueness against committed rows stays a documented gap.

* fix(unique): cover all string encodings; make format_tuple private (PR #160 review)

Addresses two Greptile P2 comments on PR #160:

- unique_key_scalar handled only StringArray (Utf8). The loud-on-unknown-type
  behavior turned any legal string column that read back as LargeUtf8 or
  Utf8View into a hard write failure (the old code silently returned None). Add
  LargeStringArray and StringViewArray arms so a legal string column is keyable
  in every physical Arrow encoding; the Err path now fires only for a genuinely
  un-keyable logical type (list/blob/vector), never a legal value in an
  unenumerated encoding.
- format_tuple was pub(crate) but only used within loader/mod.rs; make it a
  private fn (matches the old format_unique_columns it replaced, minimal
  exposed surface).

New unit test unique_key_scalar_handles_all_string_encodings pins that Utf8 /
LargeUtf8 / Utf8View all render rather than error.

feat(engine): indexed graph traversal (#149)
* perf(engine): route Expand node hydration through the id BTREE via structured filter

hydrate_nodes built an `id IN (...)` SQL string applied via Scanner::filter,
which DataFusion evaluates with InListEval (O(N×M)) rather than using the id
BTREE scalar index — measured at 72× the indexed cost on a 100k-node hop
(MR-376). Build the id IN-list as a structured DataFusion Expr, AND it with
the pushable destination filters, and apply via Scanner::filter_expr (the same
path execute_node_scan already uses); Lance then compiles it to
scalar-index-search -> take.

Destination-filter pushability is now decided by ir_filter_to_expr (structured)
instead of ir_filter_to_sql, so list-contains (array_has) pushes down too.
Removes the now-dead string-filter helpers build_lance_filter, ir_filter_to_sql,
and ir_expr_to_sql; literal_to_sql stays (still used by the mutation delete path).

* feat(engine): add TableStore::scan_edges_by_endpoint for indexed neighbor lookup

Static helper returning edge rows that match a set of endpoint keys on src/dst,
projected to [key_col, opposite_col], via a structured `key_col IN (keys)`
filter_expr. Lance routes it through the persisted BTREE on the endpoint column
(index-search -> take), so cost scales with the frontier size rather than |E|.

Unused until execute_expand's indexed mode lands; isolated in its own commit so
the storage-layer primitive is reviewable on its own.

* feat(engine): add BTREE-indexed Expand traversal path

Split execute_expand into a dispatcher over execute_expand_csr (the existing
in-memory CSR BFS, unchanged) and a new execute_expand_indexed that serves each
hop by batching the frontier into one scan_edges_by_endpoint call against the
persisted src/dst BTREE (index-search -> take), then fans out per source row.
Both share expand_hydrate_and_align — the destination hydration + alignment +
hconcat + in-memory non-pushable filters — which now aligns by string id (a
HashMap) instead of a dense row-id vec, so one tail serves both modes.

Mode selection is OMNIGRAPH_TRAVERSAL_MODE for now (default csr); the
frontier-size auto policy and lazy CSR build follow. AntiJoin stays on CSR.

tests/traversal_indexed.rs (its own #[serial] binary, so env writes never race a
reader) asserts the indexed path matches CSR for one-hop, multi-hop, cross-type,
and no-match cases, and that a freshly-appended unindexed edge is still found
(partial index coverage — fast_search=false unindexed-fragment scan).

* feat(engine): frontier-size Expand dispatcher + lazy CSR build

Replace the env-only mode switch with an auto policy: Expand uses the
BTREE-indexed path when the source frontier is small and the hop count bounded
(OMNIGRAPH_EXPAND_INDEXED_MAX_FRONTIER=1024, OMNIGRAPH_EXPAND_INDEXED_MAX_HOPS=6),
else the in-memory CSR. OMNIGRAPH_TRAVERSAL_MODE=indexed|csr still forces a mode.

Make the CSR index lazy: thread a GraphIndexHandle (memoizing OnceCell over a
Cached/Direct/None builder) through execute_query/execute_pipeline/
execute_rrf_query/execute_anti_join instead of a pre-built Option<&GraphIndex>.
A query served entirely by the indexed path with no AntiJoin never pays the
O(|E|) CSR build — the perf win of Tier 3. AntiJoin still realizes the index
(its negation uses CSR has_neighbors).

Net effect: selective traversals (the common case) skip the whole-graph CSR
build and resolve neighbors from the persisted, incrementally-maintained
src/dst BTREE. Existing traversal/aggregation/end_to_end/search suites now run
the indexed path by default and stay green.

Docs: constants.md (new env knobs), query-language.md (Expand dual path),
indexes.md (graph index is lazy + the indexed alternative).

* test(engine): bench indexed vs CSR selective traversal

Add a selective single-source knows{1,2} comparison to bench_expand: per growing
|E|, time the cold query in csr vs indexed mode (fresh db each, so CSR pays its
O(|E|) build) and assert both modes return identical rows — a guard against the
scalar-index physical_rows silent fallback dropping unindexed-fragment rows. The
existing dense hop1/2/3 latency bench is unchanged.

* feat(engine): surface silent scalar-index fallback in indexed traversal (C6)

Add TableStore::key_column_index_coverage — a metadata-only check (no IO) of
whether a `key_col IN (...)` scan will be served by the persisted BTREE or
silently fall back to a full filtered scan, mirroring Lance's own decision:
no BTREE on the column, or any fragment missing physical_rows (which disables
scalar indices for the whole scan, lance dataset/scanner.rs create_filter_plan).
execute_expand_indexed calls it once per traversal and tracing::warn!s on
Degraded, so the perf cliff is observable instead of hidden behind a bench oracle.

Detection-only: results are correct either way (the scan returns all rows). Closes
the "no silent failures" gap the traversal best-practice audit flagged as the top
deviation, and adds an IndexCoverage value a future cost-based planner can consume.

* perf(engine): dense-id BFS on the indexed traversal path (C3)

execute_expand_indexed ran its per-source BFS in string space
(Vec<HashSet<String>>, HashMap<String,Vec<String>>, ~4 String clones per neighbor
occurrence). Intern node ids to u32 once via a per-traversal TypeIndex (no
GraphIndex/CSR build — laziness preserved) and run visited/seen/frontier/
neighbor-map in dense u32 space, mirroring the CSR path; de-intern only for the
per-hop IN-list and the emitted dst ids handed to the hydrate+align tail.

Behavior-preserving — the traversal_indexed CSR-vs-indexed equivalence tests are
the guard (results are identical, the key type just changes String -> u32).

* refactor(engine): thread the opened edge dataset into indexed Expand

Hoist the edge-dataset open and the C6 index-coverage warning out of
execute_expand_indexed into execute_expand, threading the opened dataset in
as a parameter so it is opened exactly once. Extract the endpoint-column
mapping (endpoint_columns) and the coverage warning (warn_on_degraded_coverage)
as helpers.

Behavior-preserving: same dataset, same warning, same dispatch decision. This
only relocates the open so the upcoming cost-based chooser can consult index
coverage before dispatch without opening the dataset twice.

* feat(engine): cost-based Expand dispatch chooser (C5)

Replace the fixed frontier<=1024 && hops<=6 dispatch threshold with a pure,
IO-free cost model. choose_expand_mode compares the indexed path's
frontier-relative work (hops * frontier * fanout, or hops * |E| when BTREE
coverage is degraded) against the cost of building the whole-graph CSR
(BUILD_FACTOR * |E|), from cheap manifest row counts. Under good coverage this
reduces to a selectivity ratio independent of |E|, preserving the flat-in-|E|
indexed win for selective traversals while routing dense / deep / high-fanout
or degraded-and-expensive traversals to CSR.

execute_expand decides cardinality-first and only opens the edge dataset to
confirm coverage when it leans indexed (no open on a clearly-CSR traversal).
The two env knobs become hard ceilings layered on the model; the
OMNIGRAPH_TRAVERSAL_MODE override still forces a path; the chosen mode is
traced. Results are unchanged across modes — only the path differs.

Adds inline crossover unit tests and extends the traversal_indexed both_modes
harness with an auto pass asserting the chooser is result-preserving across
every traversal shape. Documents the new flag semantics in
docs/user/{constants,query-language}.md.

* test(engine): pin Lance scalar-index coverage + system-column/deletion-metadata surface

Add three Lance surface guards de-risking a future persisted-adjacency cache:
- a compile-only guard pinning the fragment physical_rows + index-detail
  surface that key_column_index_coverage mirrors (the C6 fallback);
- a runtime probe confirming a scalar BTREE on the system column
  _row_last_updated_at_version is not buildable via the normal create-index
  path (the column is not in the user schema), so a version-column range delta
  is not viable as drafted;
- a runtime probe confirming per-fragment deletion metadata
  (deletion_file.num_deleted_rows) is available as cheap O(fragments) metadata,
  the primitive a fragment-coverage delete model would rely on.

The probes turn the two largest substrate assumptions into green/red CI facts
before any cache work begins.

* test(engine): regression for cross-type id-collision in indexed traversal

A node id is unique only within a type, so a Person and a Company can share an
id string. A variable-length traversal over a cross-type edge (WorksAt) must
structurally stop after one hop. This test builds a graph where 'shared' is both
a Person and a Company id and asserts worksAt{1,2} returns only the one-hop
company. It fails today: the indexed path's single string interner de-interns
the hop-1 Company id back to the colliding Person id and runs a hop-2 scan that
matches that Person's edges, emitting a spurious second-hop company (indexed
["other","shared"] vs csr ["shared"]).

* fix(engine): structurally cap cross-type Expand at one hop

A cross-type edge cannot chain (e.g. a Company is not a WorksAt source), so a
variable-length traversal over one is structurally single-hop. Both traversal
paths now enforce this by capping max hops at 1 when from_type != to_type,
instead of relying on the hop-2 scan returning empty.

That reliance was a correctness hole on the indexed path: it interns every
endpoint string into one dense id space, so a cross-type id-string collision (a
Person and a Company sharing an id) let hop 2 de-intern a destination id back to
the colliding source-type id and match its edges, emitting rows the CSR path
never produces. With the cap the cross-type second-hop scan never runs, so the
shared interner can no longer alias across types. Turns the regression test
green (indexed == csr == ["shared"]).

* perf(engine): set-oriented filtered anti-join, remove per-row dispatch

execute_anti_join's filtered slow path sliced the outer batch to one row at a
time and re-ran the inner pipeline per row, so each 1-row inner Expand dispatched
to the indexed path — one Lance scan per outer row, while the CSR realized up
front sat unused.

Replace it with a set-oriented anti-semi-join: tag each outer row with a
synthetic index column, run the inner pipeline once over the whole frontier (the
tag survives Expand's hconcat and Filter's row-drop), then exclude outer rows
whose tag survived. The inner Expand now runs as a single set-at-a-time traversal
over the full frontier; config is read once per operator, not per row (the env
nit is mooted). A produced-but-untagged inner batch fails loudly rather than
silently keeping every row. Results are unchanged (the predicated-negation tests
exercise the path over a multi-row outer with dst-filters).

* test(engine): drop flaky wall-clock budget from the merge truth table

The 30s wall-clock assertion in merge_pair_truth_table flakes under parallel
test load: it tripped at ~31s in the full --test-threads=4 gate while passing at
~20s in isolation. A fixed time budget in a correctness test depends on machine
and parallelism, not correctness; elapsed is still logged for visibility, and a
real merge-perf regression belongs in a bench. The cell-count correctness
assertions (81 / 36 / 45) are unchanged.

* fix(engine): total deterministic ORDER via entity-key tie-break + NULL contract

apply_ordering used an unstable lexsort with no tie-break, so rows with equal
user-sort keys came out in a run-dependent order (the input order depends on
scan parallelism / upstream hashing) — making ORDER ... LIMIT non-deterministic,
a latent deny-list violation (no nondeterministic result ordering).

Append the bound entities' key columns (<var>.id, unique per row) in canonical
name-sorted order as ascending tie-breaks, giving a total, reproducible order
(and a deterministic top-N when ties straddle the LIMIT cutoff). NULL placement
(nulls_first = !descending) is unchanged and now documented as the contract.

New tests/ordering.rs locks descending, multi-key precedence, the deterministic
key tie-break (data loaded in a different order than the expected output, so it
proves the tie sorts by key not by load order), and NULL placement under ASC/DESC.
docs/user/query-language.md documents the total-order + NULL contract.

* test(engine): property-based query-correctness invariants over generated graphs

Adds a proptest harness (new dev-dep) that generates small graphs whose Person
and Company keys are drawn from a shared 5-key alphabet, so cross-type id
collisions, cycles, and self-loops arise by search rather than from one
hand-built fixture. Three invariants:

- prop_expand_indexed_eq_csr: csr == indexed == auto over knows{1,3} (same-type,
  cycles) and worksAt{1,2} (cross-type, collision-prone) from every start.
- prop_results_subset_of_existing_nodes: no phantom rows (catches over-emission
  even if both modes are wrong identically).
- prop_antijoin_partitions_persons: not{worksAt} and its complement are disjoint
  and cover all persons.

Verified the guard bites: neutering the cross-type hop cap makes
prop_expand_indexed_eq_csr fail and proptest shrinks it to persons["c","e"] /
companies["b","c"] — the cross-type collision class the hand-built fixture
only sampled once. Tests are sync + #[serial] (per-case runtime; the mode test
writes OMNIGRAPH_TRAVERSAL_MODE).

* test(engine): cover cycle/self-loop termination + nested anti-join (C5 edge cases)

- variable_hops_terminate_and_dedup_on_cycle: a 3-cycle a->b->c->a traversed with
  knows{1,5} (ceiling above the cycle length) terminates and emits each node once
  (the c->a back-edge hits the seeded source); both_modes confirms indexed == csr.
  Uses a bounded range deliberately — unbounded {1,} is a typecheck error, not a
  runtime path.
- variable_hops_handle_self_loop: a->a self-loop does not loop forever and does
  not re-emit the seeded source.
- nested_anti_join_double_negation: not { worksAt; not { name = Acme } } recurses
  through execute_pipeline, yielding [Alice,Charlie,Diana] (people with no non-Acme
  employer) — distinct from plain unemployed [Charlie,Diana].

* test(engine): execution goldens for typed-literal filters (C4 gap #4)

New literal_filters.rs covers filtering by F64/F32/Bool/Date/DateTime LITERALS
across both arms: standalone comparisons ($m.score > 1.5, $m.ratio <= 0.25,
$m.active = true, $m.born >= date(...), $m.seen < datetime(...)) exercise the
in-memory comparison path, and inline bindings (Metric { active: true },
Metric { score: 3.0 }) exercise Lance filter_expr pushdown. Seeds partition each
predicate so a dropped/miscast filter returns all rows. (Param-bound scalars and
list-column contains are covered elsewhere.)

* test(engine): full rank-order goldens for nearest + bm25 (gap #2)

Existing search tests stopped at top-1 (nearest) or non-empty (bm25), so a
regression corrupting ranks 2..k or reversing the sort direction passed CI
silently. Pin the FULL ordered slug list: nearest([0.1,0.2,0.3,0.4]) ->
[ml-intro, nlp-guide, rl-intro] (ml-intro exact at dist 0, rest by ascending
L2); bm25(Learning) -> [rl-intro, ml-intro, dl-basics] (descending score).
nearest/bm25 skip apply_ordering (is_search_ordered) and return Lance native
order, so result_slugs row order == rank order; values resolved by running and
confirmed stable across runs.

* test(engine): search fuzzy/match_text characterization + RRF non-default pairings

- match_text_matches_exact_set_excludes_unrelated: match_text(body,'neural') ==
  [dl-basics] exactly (not just contains).
- fuzzy_does_not_match_under_default_tokenizer: characterizes that fuzzy() is
  inert with the default tokenizer here (search/match_text work, fuzzy returns
  nothing); turns red — to be promoted to a real golden — if fuzzy starts matching.
- rrf_fuses_two_fts_fields / rrf_fuses_two_vector_queries: RRF fuses arms other
  than the default nearest+bm25 (bm25 title+body; two vector queries), proving
  primary_var resolves and fusion runs. New fixtures/search.gq queries +
  two_vector_params helper. Orders resolved by running, confirmed stable.

* test(engine): anti-join fast-vs-slow path equivalence harness

anti_join_fast_and_slow_paths_agree: the CSR has_neighbors fast path
(not { $p worksAt $_ }) and the set-oriented inner-pipeline replay (same
negation forced slow by an always-true $c.name != "" dst filter) must produce
the same result ([Charlie, Diana]). Closes the second real engine fork explicitly.

* test(engine): regression for nested slow-path anti-join tag collision

A nested not { ... not { ... } } where both levels hit the set-oriented slow
path collides on the fixed __antijoin_outer_row correlation column: the inner
call appends a duplicate, and column_by_name reads the OUTER tag. Fan-out (p1
works at two companies) makes inner row indices diverge from outer tags, so the
bug returns the wrong person set. Fails on current code (left ["p2","p4"] vs
right ["p3","p4"]).

* fix(engine): collision-free anti-join correlation tag for nested negation

The set-oriented anti-join tagged the outer batch with a fixed column name and
read it back by name. Under a nested slow-path anti-join the enclosing tag rides
through the inner pipeline, so the inner call produced a duplicate field; Arrow
permits duplicate names and column_by_name returns the first, so the inner
negation mis-correlated against the outer row indices.

Choose a tag name not already present in the batch (suffix-incremented), so each
nesting level reads its own correlation column. Turns the fan-out regression
green; the existing nested/fast-vs-slow/proptest anti-join invariants still pass.

* fix(engine): cap cross-type hops in the Expand cost model

gather_cost_inputs fed the requested max_hops into choose_expand_mode even though
execute_expand_indexed runs at most one hop for a cross-type edge. So a cross-type
variable-length expand (e.g. worksAt{1,5}) had its indexed cost scaled by 5 while
only one hop runs, skewing the chooser toward CSR (an unnecessary whole-graph
build) near the crossover. Results were unaffected (modes are equivalent); this
is a plan-accuracy fix.

Add cost_effective_hops(requested, same_type) — caps to 1 for cross-type — and
apply it in gather_cost_inputs so the estimate matches what executes. Unit test
covers the cap and the crossover consequence (capped 1 hop stays indexed where
the requested 5 would have flipped to CSR).

* perf(engine): realize anti-join CSR lazily + reuse a warm CSR in the chooser

Two CSR build/reuse fixes flagged on the set-oriented anti-join work (results
unchanged — plan/perf accuracy):

- execute_anti_join called graph_index.get() (the O(|E|) whole-graph CSR build)
  unconditionally, but only the bulk fast path consumes it; a filtered/nested
  slow-path anti-join's inner Expand picks its own access path. Gate the build on
  a pure shape predicate (bulk_anti_join_applies) so a selective anti-join over a
  large graph no longer pays a build it won't use.
- gather_cost_inputs hardcoded csr_cached=false, so once an earlier op realized
  the CSR, later Expands still cost it as a cold build and could pick per-hop
  indexed scans over reusing the warm in-memory CSR. Add GraphIndexHandle::
  is_built() and thread it through so the chooser reuses a materialized CSR.

Anti-join, cross-type, proptest-equivalence, and chooser unit tests stay green.

* test(engine): RAII traversal-mode guard in proptest equivalence

prop_expand_indexed_eq_csr set/cleared OMNIGRAPH_TRAVERSAL_MODE manually; a panic
between set and clear (e.g. a query unwrap on a generated case) would leak the
forced mode into proptest's shrink/subsequent cases and mask the divergence under
test. Replace with a ModeGuard that clears on drop (including on unwind), scoping
the forced mode to a single query.

* test(engine): regression for multi-hop anti-join hop bounds

The bulk anti-join fast path answers via has_neighbors (one-hop existence), so
not { $p knows{2,2} $x } wrongly drops a node with a 1-hop neighbor but no
2-hop path. On a->b (sink) and c->d->e, only c has a 2-hop path; the query should
keep [a,b,d,e]. Fails on current code (left ["b","e"] — only the sinks).

* fix(engine): restrict anti-join bulk fast path to one-hop expands

bulk_anti_join_applies accepted any single Expand, but try_bulk_anti_join_mask
decides via the CSR has_neighbors one-hop existence check — wrong for multi-hop
negations. Require min_hops==1 && max_hops==1 in the predicate; anything else
falls to the slow path, whose inner Expand runs the real bounded traversal.
Turns the multi-hop regression green; one-hop anti-joins unchanged.

* fix(engine): IndexCoverage reports Degraded for uncovered fragments

key_column_index_coverage checked BTREE-exists + physical_rows but not that the
index actually covers the current fragments. Since edge-index creation is skipped
once a BTREE exists, fragments appended later stay unindexed while coverage still
reported Indexed — so the cost chooser priced a partly-full scan as fully indexed.

Compare the BTREE's fragment_bitmap (public on lance_table IndexMetadata) against
the dataset's current fragment ids; report Degraded when any are uncovered. A None
bitmap means Lance can't report coverage — don't over-degrade. Results are
unaffected (the scan returns unindexed-fragment rows either way); this corrects
the cost signal.

Test: a freshly-loaded edge BTREE is Indexed; after appending an edge the new
fragment is uncovered → Degraded. Surface guard pins IndexMetadata.fragment_bitmap.

* docs: clarify the Expand frontier ceiling bounds the initial dispatch frontier

The cap is applied at dispatch on the initial frontier; per-hop fan-out
(union_dense) is not hard-capped. Correct the constants.md and query-language.md
claims: the ceilings bound the initial-dispatch frontier/hops, the cost model
estimates total indexed work as ~hops*frontier*fanout (pricing dense fan-out
toward CSR), and per-hop work is not a hard bound. Drops the overstated 'hard
caps bound indexed work' / 'cost ∝ frontier' wording.

fix(loader): enforce composite @unique(a, b) as a true composite key (#133)
* fix(loader): enforce composite @unique(a, b) as a true composite key

Node/edge composite uniqueness constraints were flattened into a single
list of property names, so @unique(a, b) was enforced as independent
single-field checks @unique(a) AND @unique(b) at intake. Preserve the
constraint grouping and check each group as a composite key, mirroring
the merge-path enforcement. Error messages now name the full composite.

MR-983

* docs: clarify unit-separator comment in composite unique check

* docs: fix separator reference in composite unique comment (merge.rs also uses U+001F)

* fix(merge): align composite @unique key separator with intake (U+001F)

The branch-merge path (update_unique_constraints) joined composite key
columns with '|', while intake joins with U+001F. The same @unique(a, b)
was keyed two different ways, and '|'-join can raise phantom merge
conflicts for values containing '|' (e.g. ('x|y','z') vs ('x','y|z')).

Factor the tuple-join into one shared helper (loader::composite_unique_key)
so the intake and merge paths cannot drift again. Add branching regression
tests for edge @unique(src, dst) on the merge path.

Refs MR-983.

fix(maintenance): route uncovered drift through repair (#156)
* docs(invariants): note the non-atomic manifest->commit-graph publish gap

Every graph publish commits __manifest then appends _graph_commits as two
separate writes; a crash between them leaves the manifest ahead of the commit
DAG. Live reads + durability are unaffected (reads resolve via the manifest) and
recovery does not repair it; impact is bounded to commit history / time-travel
by commit id / merge-base completeness. Pre-existing across all publishes, not
the optimize reconcile specifically. Documented as a Known Gap; the fix is a
commit-graph reconcilable from the manifest, not a recovery sidecar.

fix: optimize publishes compaction; recovery roll-back converges manifest (#141)
* test(optimize): cover manifest publish + HEAD-drift reconcile

Red against the pre-fix optimize, which ran compact_files without
publishing the compacted version to __manifest:

- maintenance: optimize must publish so the manifest table_version
  tracks the compacted Lance HEAD and a later schema apply succeeds;
  and must reconcile a pre-existing manifest-behind-HEAD drift (forged
  via raw Lance compaction) so strict writes commit again.
- end_to_end + composite_flow: post-optimize query / strict update /
  reopen in the full lifecycle (the canonical flow previously omitted
  post-optimize writes as a documented "known limitation").
- failpoints: a crash between compaction and the manifest publish rolls
  forward on next open.

* fix(optimize): publish compaction to manifest and reconcile HEAD drift

optimize ran Lance compact_files without publishing the new version to
__manifest, so the manifest table_version lagged the Lance HEAD: reads
stayed pinned to the pre-compaction version, and the next schema apply or
strict update/delete failed its HEAD-vs-manifest precondition with
"stale view ... refresh and retry" (open-time recovery rollback inflated
the gap on retry).

optimize now publishes each compacted table's version under the
per-(table, main) write queue, guarded by a manifest CAS and a
SidecarKind::Optimize recovery sidecar (loose-match; roll-forward is safe
because compaction is content-preserving). When a table has nothing left
to compact but its Lance HEAD is already ahead of the manifest pin
(pre-fix drift, or a recovery restore commit), optimize reconciles the
manifest forward to HEAD (metadata-only, no sidecar). Caches and the
CSR/CSC graph index are invalidated after a publish.

Docs updated (maintenance, storage, branches-commits, writes, testing).

* test(recovery): rollback convergence + optimize-defer regressions

Red against the current code, landed before the fix:
- recovery: after the open-time sweep rolls a sidecar back, the manifest
  must track Lance HEAD (no residual drift) so a follow-up schema apply
  succeeds — the original "+1 per retry" loop. Today roll-back restores
  without publishing, so the manifest lags HEAD and the apply fails its
  HEAD-vs-manifest precondition.
- maintenance: optimize must refuse while a recovery sidecar is pending —
  operating on an unrecovered graph could publish a partial write the
  sweep would roll back.

Also removes optimize_reconciles_preexisting_manifest_head_drift: the
ad-hoc drift reconcile it covered is replaced by recovery-side convergence.

* fix(recovery): converge manifest on roll-back; optimize defers on pending recovery

Root of PR #141's review findings and the original "+1 per retry" loop:
a Lance HEAD ahead of the manifest was ambiguous (benign content-preserving
drift vs. a partial write a sidecar will roll back), and optimize's reconcile
guessed it benign. Close the class instead of guessing:

- Recovery roll-back now PUBLISHES the restored version (via a
  push_table_update_at_head helper shared with roll-forward), so the manifest
  tracks the Lance HEAD after recovery — symmetric with roll-forward. This
  fixes the +1 loop (after one roll-back the retry's HEAD-vs-manifest
  precondition passes) and removes the only remaining source of orphaned
  drift. The audit still records the logical rolled-back-to version; the
  manifest is published at the restore commit (identical content).
- optimize drops the ad-hoc drift reconcile and instead REFUSES when a
  __recovery sidecar is pending, so it only ever operates on a recovered
  graph (manifest == HEAD); its compaction publish can no longer commit a
  partial write. With the reconcile gone, the blob-skip-vs-reconcile gap is
  moot.

Updates the rollback recovery-test helper (manifest == HEAD after roll-back),
the failpoints assertions, and the user/dev docs.

* test(recovery): fix rollback assertion for manifest convergence

The roll-back-publishes change makes the manifest version advance after a
SchemaApply roll-back (to the old-schema content), so the
schema_apply_without_schema_staging_rolls_back_on_next_open assertion must
be `version > pre`, not `version == pre`. This update was dropped during
the commit churn and surfaced as a CI Test Workspace failure; the
old-schema-preserved intent stays covered by count_rows + _schema.pg + the
RolledBack convergence invariant.

fix(loader): accept multi-line (pretty-printed) JSON in load (#146)
The loader read input line-by-line (reader.lines() + serde_json::from_str per line), so any delta where a JSON object spanned multiple lines failed with 'invalid JSON on line 1: EOF while parsing an object'. Compact JSONL worked; pretty-printed JSON never did.

Switch to a streaming value deserializer (Deserializer::from_reader().into_iter::<Value>()), which treats any whitespace (including newlines inside objects) as a separator — so both compact JSONL and pretty-printed JSON load. Error labels switch from line numbers to record numbers (line numbers are meaningless once objects span lines).

feat(engine): sweep & remove legacy __run__ branch guard (MR-770) (#132)
* feat(engine): sweep legacy __run__ branches via v2→v3 manifest migration

Pre-v0.4.0 graphs can carry stale `__run__<id>` staging branches on the
`__manifest` dataset, left by the Run state machine removed in MR-771. Lance's
`list_branches` still enumerates them, so they leak into `branch_list()` and
count as blocking branches at schema-apply time.

Add a one-time `migrate_v2_to_v3` arm to the internal-schema dispatcher: on the
first read-write open it enumerates `__manifest` branches, deletes every
`__run__*` ref, and bumps the stamp to 3. Idempotent under retry (re-enumerates
fresh each run). The `"__run__"` prefix is inlined so the migration does not
depend on the run_registry guard that MR-770 removes next.

This is the prerequisite sweep; the guard removal follows in the next commit.

* refactor(engine): remove the legacy __run__ branch guard (MR-770)

With the v2→v3 migration sweeping stale `__run__*` branches off `__manifest`
on first read-write open, the defense-in-depth `is_internal_run_branch` guard
is no longer needed.

- delete `db/run_registry.rs`; drop the module + re-export from `db/mod.rs`
- collapse `is_internal_system_branch` to the schema-apply-lock check only
- `ensure_public_branch_ref`: drop the run-ref rejection; `__run__*` is now an
  ordinary branch name
- `branch_merge`: reject `is_internal_system_branch` (was run-only) so the
  schema-apply lock is rejected consistently with create/delete — a small,
  deliberate tightening
- update the inline schema-apply test + the writes integration tests
  (`public_branch_apis_reject_internal_run_refs` →
  `public_branch_apis_reject_internal_system_refs`, which also asserts
  `__run__*` now creates successfully)
- docs: flip the "pending production sweep / defense-in-depth" notes to
  "auto-swept by the v2→v3 migration"; document the read-only-open limitation

Known residual: the inert `_graph_runs.lance` / `_graph_run_actors.lance` bytes
remain until a `StorageAdapter::delete_prefix` primitive lands.

* fix(engine): run __run__ sweep at Omnigraph::open, not only on publish

Review (PR #132) caught a regression: removing __run__ from
`is_internal_system_branch` exposed legacy `__run__*` branches to the
schema-apply blocking-branch checks (schema_apply.rs:104 and :778) and to
`branch_list()`, but the v2→v3 sweep ran only inside the publisher's
`load_publish_state`. On a pre-v0.4.0 graph whose first write is a schema
apply, the blocking-branch check fires before any publish, so apply failed
with "found non-main branches: __run__…". The same lazy timing also created a
reverse hazard: a user-created `__run__*` branch on a still-v2 graph could be
deleted by the first publish's sweep.

Fix: run the internal-schema migration in `Omnigraph::open(ReadWrite)` (new
`manifest::migrate_on_open`), before the coordinator reads branch state. The
sweep now lands before any branch-observing code, and a graph is stamped v3 at
open — so the one-time sweep can never catch a legitimately-created branch.
Both checks and `branch_list` see the swept graph; correct by construction for
every write path.

Accepted residual: a read-only open of an unmigrated legacy graph still lists
`__run__*` (read-only opens must not write, so they can't sweep). Documented.

Regression test `legacy_run_branch_is_swept_on_open_and_does_not_block_schema_apply`
confirmed RED before the fix (panicked on the branch_list leak assertion) and
GREEN after. Also updates the stale schema_apply.rs comment, the writes.md
"Migration code" section, and adds the v3 row to storage.md's migration table.

* test(engine): sweep multiple legacy __run__ branches; doc nit

Strengthen the v2→v3 migration test to synthesize three `__run__*` branches
(a real legacy graph accumulates one per run) so the migration's delete loop
is exercised on a single reused dataset handle, not just a single branch.
Confirms multi-branch deletion is safe.

Also drop a stale "active runs" reference from the branch_delete doc line.

* fix(engine): force-delete in __run__ sweep for concurrency safety

`migrate_v2_to_v3` ran `Dataset::delete_branch` (= `branches().delete(.., false)`),
which errors "BranchContents not found" if the branch is already gone. Since the
sweep now runs in `Omnigraph::open(ReadWrite)`, two processes opening the same
legacy v2 graph concurrently would race: one wins each delete, the other's open
fails. The migration only claimed idempotency under *sequential* retry.

Switch to `Dataset::force_delete_branch` (= `delete(.., true)`), Lance's
documented path for cleaning up zombie branches, which tolerates an
already-absent branch. The sweep is now idempotent under concurrent runners and
robust to partial/zombie state. Found in self-review; no behavior change for the
common single-open path.

* docs(release): note MR-770 __run__ cleanup in v0.6.1

* docs(branches): reconcile branch cleanup semantics

* 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.

Stored-query registry foundation + config/CLI RFC-002 (#128)
* MR-969: add stored-query registry config surface

Introduce the `queries:` block in omnigraph.yaml — an inline
`name -> entry` map of stored queries, per-graph
(`graphs.<id>.queries`) and top-level for single-graph mode, mirroring
how `policy` is wired in both modes. Each entry points at a `.gq` file
and carries optional MCP exposure settings (`expose`, `tool_name`),
defaulting to not-exposed.

Additive: absent `queries:` leaves current behavior unchanged.

- QueryEntry { file, mcp: McpSettings { expose, tool_name } }
- `queries` field on TargetConfig + OmnigraphConfig (serde default)
- query_entries() / target_query_entries() accessors
- resolve_query_file() — base_dir-relative `.gq` path resolution
- round-trip + absent-block tests

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* Add stored-query registry loader and GraphHandle wiring

Add a `queries` module: QueryRegistry loads each declared `.gq` entry,
parses it, and selects the query whose symbol matches the manifest key,
asserting the two agree (key == `query <name>` symbol). Identity is the
query name; a key/symbol mismatch is a load-time error. Errors are
collected, not fail-fast, so a bad registry surfaces every broken entry
at once. Schema type-checking is deliberately left to a separate pass so
the loader stays callable without an open engine.

Thread an `Option<Arc<QueryRegistry>>` through GraphHandle alongside the
per-graph policy; the URI-canonicalizing clone propagates it. Production
openers default to None for now — the boot path loads and attaches the
registry in a later change.

- QueryRegistry::{from_specs, load, lookup, iter}; StoredQuery::is_mutation
- GraphHandle.queries field, propagated on canonical clone
- registry unit tests: identity match/mismatch, multi-query selection,
  per-entry parse errors, error collection, mutation classification

* docs: add RFC-002 config & CLI architecture

Layered config (user-global ~/.config/omnigraph/ + per-project), a
unifying `target` abstraction resolving to (locus, graph, sub-state,
credential) with embedded-URI XOR remote-server loci, multi-server ×
multi-graph client targeting, credentials by-reference, and the
file-naming decision: project and server config are one artifact
(`omnigraph.yaml`); the only differently-named file is the user-global
`config.yaml`, split by scope not role. Includes the 12-factor bind
portability rule (prefer --bind/OMNIGRAPH_BIND over a committed
server.bind) and the defined-locally / invoked-remotely model for
stored queries. Derived from first principles working backwards from
what the engine enables; validated against kube/Helix/git/compose.

Linked from docs/dev/index.md. Proposed; phased rollout for the
MR-973/974/981 family.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* Add check() to validate stored queries against the live schema

A pure check(registry, catalog) that type-checks every stored query via
the same typecheck_query_decl the engine runs for inline queries — no
parallel implementation. Failures are collected, not fail-fast, so an
operator sees every broken query (e.g. a type/property a migration
renamed or removed) in one pass. Breakages are fatal (the boot path will
refuse to start); warnings are advisory.

Pure over (registry, catalog) so it is callable both at boot (engine
catalog) and offline from the CLI without an open engine.

Advisory lint: an mcp.expose:true query that declares a Vector(N)
parameter warns — an LLM cannot supply a raw embedding vector; such a
query should take a String parameter and embed server-side. Warns
rather than rejects, since service-to-service callers may pass vectors.

- CheckReport { breakages, warnings }; has_breakages / is_clean
- tests: valid query, unknown type, unknown property, collect-not-fail-fast,
  vector-param-exposed warns, unexposed silent

* Drop internal plan-label refs from stored-query config comments

* docs: reconcile aliases with the role model in RFC-002

Place the existing client-only `aliases:` block in the client/server
role split: aliases are client-role (CLI, embedded, ungated) and may
live in both user-global and project config; `queries:` is server-role
(deployment manifest only). They overlap as "name -> .gq"; `queries:` is
the superset, and the end-state subsumes aliases (definition -> queries,
target/branch/format -> client invocation context, positional args ->
CLI sugar). v1 keeps aliases unchanged.

* docs: make RFC-002 config global-first, project-optional

The global user config is the primary, self-sufficient default; the
CLI works from any directory with no project file (the kubectl/aws/gh
posture), a deliberate flip from today's project-anchored behavior.
The project omnigraph.yaml becomes an optional repo-scoped override and
the deployment manifest. Uniform schema, both layers optional; global
can hold any section including a personal server's graphs/queries.
Additive: project still overrides global; the flip adds a fallback
layer below the project file rather than removing it.

* docs: justify XDG ~/.config/omnigraph over legacy ~/.omnigraph in RFC-002

Make the rationale explicit: XDG-first because OmniGraph is a client
that will cache remote catalogs and keep session state alongside
secrets, and XDG separates config / cache / state into distinct dirs
(clear cache without touching creds; backups skip cache) whereas a
single ~/.omnigraph/ mixes them. Honor ~/.omnigraph/ as a fallback for
the peer-group (aws/kube/docker/helix) expectation. Add XDG_CACHE_HOME
/ XDG_STATE_HOME to the override precedence.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* docs: build RFC-002 credentials on the existing env-file mechanism

OmniGraph already has credentials-by-reference: bearer_token_env names
the env var, and auth.env_file is a git-ignored dotenv the CLI
auto-loads (real env vars win), resolved via resolve_remote_bearer_token.
The RFC's proposed credentials.yaml + token_env were redundant parallel
inventions. Reconcile: reuse bearer_token_env (extend to
servers.<name>) and auth.env_file (add a global ~/.config/omnigraph/.env
layered under the project .env.omni); OS keychain is an additive future
resolver. No new credentials.yaml. Updated summary, non-goals,
background, file-naming, credentials, example, login, migration, rollout.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* docs: use single ~/.omnigraph dir (Helix-style), not XDG, in RFC-002

Reverse the earlier XDG-first call. The prior argument rested on a false
dichotomy (single-dir => mixed config/cache/state); in fact the peer
tools (aws, kube, helix) achieve separation via SUBDIRECTORIES inside
one ~/.tool/ dir (~/.aws/sso/cache/, ~/.kube/cache/), getting cache
hygiene AND one discoverable place. So everything goes under
~/.omnigraph/: config.yaml, credentials (dotenv, 0600), cache/, state/.
Lower cognitive load, matches what DB/cloud-CLI users expect, matches
Helix. OMNIGRAPH_HOME overrides; $XDG_CONFIG_HOME optionally honored but
~/.omnigraph/ is canonical. Updated all paths, the rationale paragraph,
the file-naming table (added a cache/state row), and env precedence.

* docs: reconcile RFC-002 with shipped/planned CLI tickets

Align with reality found in existing tickets:
- Noun is graph/graphs, not target/targets (MR-603 done renamed the
  config key targets->graphs, flag --graph). Use graphs:/--graph; an
  entry is embedded (uri) XOR remote (server + remote graph name).
- ~/.omnigraph/ confirmed by MR-581 (og template pull, done) which
  already quick-starts templates there.
- Templates already exist (MR-581/MR-531) — not invented here.
- The init family is already specced (init, quickstart MR-973, serve
  MR-970, prune MR-972, mcp install MR-974, agent-mode MR-981); this
  RFC only adds the user route (~/.omnigraph/config.yaml + login).
- aliases: -> operations: planned (MR-839).
- bearer_token_env gap tracked in MR-971.
- query lint/check already exist (MR-639) — registry validator must not
  collide with the singular `query check`.
Add a Reconciliation section; fix the canonical example to graphs:/--graph.
Also: merge semantics refined (deep-merge settings, replace named
entries, replace lists, config view --resolved --show-origin).

* docs: correct stale-ticket claims and fold init/bootstrap design into RFC-002

Verify against code, not ticket statuses (MR-581 is marked done but is
stale/unbuilt): no ~/.omnigraph usage, no template/serve/quickstart/
prune/login commands exist; config still uses aliases: (no operations:).
So ~/.omnigraph/ stands on peer-convention merits alone, and templates
are a design question, not a foothold. Add §7.5: the three-tier init
model (user route = login + ~/.omnigraph/config.yaml; thin project init;
fat quickstart + templates) with first-principles positions (split
init/login, in-place refuse-if-exists, interactive vs --auto/agent-mode,
--template flag, secrets-on-scaffold gitignore rule). This RFC owns only
the user route; the rest are sibling tickets (MR-973/970/972/974/981).

* docs: breadboard + slice Shape A in RFC-002

Add the implementation breadboard (places P1-P5, affordances N1-N14 with
NEW markers, mermaid) and five vertical slices for the selected config/
CLI/init shape: V1 global layer + merge engine + config view; V2 remote
graphs + HTTP-client path + credential resolution; V3 omnigraph login;
V4 init-hardening + quickstart + templates (rides MR-970); V5 agent-mode
(MR-981). Rollout reordered to the slice sequence; spikes X1-X4 gate
their owning slice. V1-V2 close the substantive client->server gap.

* Add InvokeQuery Cedar action (coarse, graph-scoped)

A per-graph, branch-scoped action that gates invoking a server-side
stored query by name. Coarse for now: an `invoke_query` allow rule
permits any stored query on the graph; a future, additive refinement
adds an optional per-query-name scope without changing rules written
against the coarse action. Enforcement is at the HTTP boundary; the
engine `_as` writers still enforce read/change per the query body, so a
stored mutation is double-gated (invoke_query to reach the tool, change
for the write). No call site yet — the invocation handler wires it in a
later change (same pattern as Admin/GraphList added ahead of consumers).

- variant + as_str/resource_kind(Graph)/FromStr/uses_branch_scope
- Cedar schema: invoke_query appliesTo Graph
- tests: per-graph allow/deny, branch-scope accepted

* Load and type-check stored queries at server boot, refusing breakage

At startup the server now loads each graph's stored-query registry,
type-checks every query against that graph's live schema, and refuses to
boot if any query references a type/property the schema doesn't have
(same posture as bad policy YAML) — so schema drift surfaces at the
deploy boundary, not silently at invocation. Non-blocking warnings are
logged. The validated registry is attached to the GraphHandle (the two
production sites previously held `queries: None`).

Loading (parse + key==symbol identity) happens at settings-build time
where the config is in scope; the schema type-check happens after each
engine opens (single mode in `open_single_with_queries`, multi mode in
`open_single_graph`). `open_with_bearer_tokens_and_policy` delegates
with an empty registry so its 18 test callers are unchanged; the public
`new_*` constructors are unchanged (only the private build path threads
the registry).

- ServerConfigMode::Single / GraphStartupConfig carry the loaded registry
- boot tests: valid registry boots; type-broken query refuses boot + names it

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* Add `omnigraph queries validate` and `queries list` CLI

`queries validate` type-checks the stored-query registry against the
live schema offline — it opens the selected graph, runs the same
check() the server runs at boot, prints breakages/warnings (human or
--json), and exits non-zero on any breakage — so an operator can catch
a query broken by a schema change without restarting the server.
`queries list` prints each registered query's name, MCP exposure, and
typed params.

Named `validate` (not `check`) to avoid overlap with the existing
`omnigraph lint` — `query check`/`query lint` are already deprecated
argv-shims to `lint`. Registry entries resolve like the server: a named
graph uses its per-graph `queries:`; otherwise the top-level one.

- Queries subcommand group; reuses QueryRegistry::load + check from
  omnigraph-server; local-only (needs the schema), mirrors lint
- tests: clean registry exits 0, broken query exits non-zero + names it,
  list shows the query and its typed params

* Route registry selection through one shared query_entries_for

The "which queries: block applies for graph X" rule existed twice — the
server boot path and the CLI's registry_entries — and had already drifted:
the CLI carried an unreachable unwrap_or_else fallback the server lacked.

Add OmnigraphConfig::query_entries_for(graph: Option<&str>) as the single
definition (named graph -> its per-graph block; otherwise top-level) and
route all three sites through it: server single mode, server multi-graph
loop, and the CLI. The CLI's dead fallback arm is deleted; CLI and server
now resolve identically by construction.

No behavior change. Extends the config round-trip test to pin the selector,
including the unknown-name -> top-level fallback the deleted CLI arm covered.

* Funnel registry validation through one validate_and_attach gate

The check -> refuse-on-breakage -> log-warnings -> empty->None block was
copy-pasted across both open paths (single mode and the multi-graph
per-graph open), differing only by the graph label. A third opener could
attach a registry that was never schema-checked.

Extract validate_and_attach(queries, catalog, label) -> Option<Arc<..>> as
the single gate both paths call, so attaching an unchecked registry is no
longer expressible. The catalog handle is an owned Arc, so calling it
before the multi-mode policy match (which rebinds db) is borrow-clean.

No behavior change. Adds a direct unit test of the helper (empty / clean /
breakage incl. the graph label in the message) — covering the multi-graph
path's logic, which previously had no boot-refusal coverage.

* Resolve param types structurally in the MCP vector lint

The exposed-query advisory detected vector params with
type_name.starts_with("Vector(") — a second copy of the compiler's own
ScalarType::from_str_name vector parsing that could drift from it.

Key the lint off PropType::from_param_type_name + ScalarType::Vector(_)
instead, the one canonical resolver the type system already uses. Any
future param-suppliability lint now reads the structured type rather than
scanning the surface string.

Behavior-preserving: the grammar forbids list-of-vector params
(list_type = "[" base_type "]", and base_type excludes Vector), so the only
input where the structured and string checks could differ is unparseable.
Adds a guard test that an exposed String param does not false-trigger the
warning.

* Refuse duplicate MCP tool names across exposed stored queries

The effective MCP tool name (explicit tool_name, else the query name) is a
second identity namespace beside the registry key, but nothing enforced it
unique — two exposed queries could claim one catalog key, and each consumer
re-derived the name ad hoc.

Add StoredQuery::effective_tool_name() as the one definition, and a
load-time uniqueness pass in from_specs over exposed queries: a collision is
a collected LoadError naming the loser and the winner. Scoped to exposed
queries (unexposed have no MCP tool); deterministic over the BTreeMap so the
first-declared wins and the error order is stable.

New (rare) refusal: a config with colliding exposed tool names now fails
`omnigraph queries validate` offline and refuses server boot, the same
posture as a malformed registry. Release-note-worthy.

Test-first: duplicate_exposed_tool_name_is_a_load_error (red before the
pass, green after) + a CLI offline test; the unexposed sibling pins the
exposed-only scope; effective_tool_name asserts folded into the load test.

* docs: document the queries registry, CLI, and invoke_query action

The stored-query surface shipped without user docs. Add it, per the same-PR
maintenance contract:

- policy.md: invoke_query as per-graph action #10 (branch-scoped), with the
  double-gating note; renumber graph_list; add it to the branch_scope list.
- cli-reference.md: the `queries validate | list` command, and the
  `queries:` config block (per-graph + top-level) with mcp.expose/tool_name
  and the tool-name uniqueness rule.
- server.md: boot-time stored-query type-check (refuse on breakage), noting
  invocation over HTTP/MCP is not yet exposed.

* Add POST /queries/{name} stored-query invocation handler

Invoke a curated server-side stored query by name: source + name come from
the per-graph queries: registry, the client sends only runtime inputs
(params, branch, snapshot). Gated by the invoke_query Cedar action at the
boundary; the handler delegates to the existing run_query/run_mutate, whose
inner Read/Change enforce still runs — so a stored mutation is double-gated
(invoke_query to reach the tool, change for the write).

- InvokeStoredQueryRequest + an untagged InvokeStoredQueryResponse
  { Read(ReadOutput), Change(ChangeOutput) } → one Json<_> return type and a
  oneOf 200 schema (a correct contract, not a wrong-but-simple one).
- Route lives in per_graph_protected → single-mode /queries/{name} and
  multi-mode /graphs/{id}/queries/{name} for free.
- Deny == unknown: an invoke_query denial and a missing query both return the
  same 404, so the catalog can't be probed by an unauthorized caller.
- OpenAPI regenerated; tests cover read, mutation double-gate (403 vs 200),
  bad-param 400, and the identical-404 deny path.

Completes the MR-969 V1 invocation slice (registry + /queries/{name} + invoke_query).

* docs: stored-query invocation endpoint; flip the not-yet-exposed caveat

Now that POST /queries/{name} ships (C7), document it: add the endpoint to
server.md's inventory + an invocation section (body, untagged read/mutate
envelope, invoke_query gate, double-gated mutations, deny == 404), and flip
the startup note that said invocation was not yet exposed. In policy.md,
replace "no invocation call site yet" on the invoke_query action with a
pointer to the endpoint.

* Scope the stored-query 404-hiding claim to non-invoke_query callers

Review found the deny==404 catalog-hiding was overstated as a contract: it
holds only at the outer invoke_query gate. A caller that HOLDS invoke_query
but lacks read/change gets the inner gate's 403 for an existing query vs 404
for an unknown one — so existence is visible to grant-holders by design (the
intended double-gate). The handler docstring, OpenAPI 404 description, and
server.md all claimed the 404 was airtight against any denied actor.

Correct the wording in all three (no behavior change) and add the missing
symmetric test (invoke_query but no read -> 403 for an existing query, 404
for unknown) so the actual contract is pinned. Also document that in
default-deny mode (tokens, no policy) every invocation 404s until an
invoke_query rule is configured.

Nits: the from_specs collision comment said "first declared wins" but it is
lexicographically-first by name (BTreeMap); the effective_tool_name docstring
overclaimed the CLI display routes through it (it resolves the rule on its
own output DTO).

* Default mcp.expose to true (the manifest entry is the opt-in)

expose controls MCP-catalog membership only — it is not an authorization
gate (invocation is gated by invoke_query regardless). So requiring a
per-query mcp.expose: true was friction with no safety benefit: a
non-exposed query is still HTTP-invocable by name. Flip the default so
declaring a query in the manifest exposes it to the agent tool catalog by
default; expose: false is the escape hatch for service-only queries.

Both the absent-mcp path (Default impl) and the present-but-no-expose path
(serde default fn) now yield true. Doc comments + cli-reference updated; the
config round-trip test asserts the new default.

* Add GET /queries stored-query catalog endpoint

List a graph's mcp.expose stored queries as a typed tool catalog so a client
(the MCP server) can register them as tools without fetching .gq source.
Each entry carries name, MCP tool_name, description/instruction, a
read/mutate flag, and decomposed typed params (kind enum: string|bool|int|
bigint|float|date|datetime|blob|vector|list, plus item_kind for lists and
vector_dim) — so the consumer builds an input schema with a closed match and
never re-parses omnigraph type spelling. I64/U64 are bigint (string on the
wire): a JSON number loses precision past 2^53 and the engine already accepts
decimal strings.

Read-gated (works in default-deny; the catalog is graph-wide, authorized
against main). NOT Cedar-filtered per query yet — a reader can list a query
whose invoke_query they lack (documented gap until per-query authz lands);
invocation stays invoke_query-gated + deny==404.

- api: QueriesCatalogOutput / QueryCatalogEntry / ParamDescriptor / ParamKind
  + query_catalog_entry (reuses PropType::from_param_type_name; scalar_kind is
  exhaustive, so a new ScalarType is a compile error here until catalogued).
- GET /queries route in per_graph_protected (→ /graphs/{id}/queries in multi
  mode); OpenAPI regenerated; path allowlists updated.
- Tests: projection unit (every kind, list, vector, nullable, mutation,
  empty) + handler (exposed-only filter, read-gate probe-oracle, empty
  registry).

* docs: GET /queries stored-query catalog endpoint

Document the catalog: the endpoint table row (GET /queries, read-gated), a
catalog section (typed-param kind enum, bigint/date/datetime/blob-as-string,
graph-wide/branch-independent, mcp.expose default true, the read-gated
probe-oracle gap), and flip the startup note now that the catalog ships.

* Collect file-I/O and parse errors in QueryRegistry::load in one pass

load() early-returned on any unreadable .gq file, masking parse / identity /
tool-name-collision errors in the OTHER (readable) files — so an operator
fixed the missing file, restarted, and only then saw the next broken query.
Now it collects I/O errors but still runs from_specs on the readable specs
and returns the union, so every broken entry surfaces at once (matching the
collected-errors contract the rest of the registry already follows).

Safe: from_specs' tool-name collision check runs over loaded queries only, so
dropping an I/O-failed entry can only under-report a collision, never invent
one. I/O errors are ordered first (BTreeMap key order), then spec errors.

Adds a load-level test (tempdir: a valid, a missing, and a parse-broken .gq)
asserting all three surface in one Err — confirmed red before the fix.

* Make invoke_query graph-scoped (one branch authority)

invoke_query gates reaching the curated stored-query surface — a graph-level
capability. Per-branch/snapshot access is already enforced by the inner
read/change gate in run_query/run_mutate (authorized against the resolved
branch), so branch-scoping the outer gate was redundant AND wrong for snapshot
reads (it defaulted to main). Drop the branch dimension: remove InvokeQuery
from uses_branch_scope (it joins admin as graph-scoped) and authorize the
boundary gate with branch: None.

Lossless: an actor confined to branch X by their read/change rules can still
only invoke a stored query that touches X. A rule that sets branch_scope on
invoke_query is now rejected by validate() — write invoke_query in its own
rule.

Ripple (atomic): restructure the server invoke fixture so invoke_query sits in
its own branch_scope-free rule; invert invoke_query_is_branch_scoped ->
invoke_query_rejects_branch_scope; the per-graph authorize test uses
branch: None; docs (policy.md, server.md, the InvokeQuery doc). No wire/OpenAPI
change.

* Resolve graph config by identity, not server mode

Which policy/queries block applies for a graph was decided three different,
mode-dependent ways: single-mode boot used top-level even for a named graph;
multi-mode used per-graph (and silently ignored a top-level queries block); the
CLI used per-graph for a named target. So `queries validate --target prod`
could check a different registry than the single-mode server loaded, and a
named graph's per-graph policy/queries were silently shadowed.

Make config a function of graph IDENTITY: a graph served by NAME
(--target/server.graph, a graphs: entry) uses its own graphs.<name>.{policy,
queries}; a bare URI is anonymous and uses top-level. One rule, applied by
single-mode boot, multi-mode boot, and the CLI — so they can't diverge and the
CLI predicts the server exactly.

No silent ignore: serving a named graph while a top-level policy/queries block
is populated now refuses boot, naming the block (the multi-mode top-level-policy
bail, extended to queries and to single-mode-named). The CLI's `queries
validate` derives the schema URI and the registry from ONE selection, and a
positional URI forces anonymous (ignoring cli.graph) so the two can't come from
different graphs.

BREAKING (released behavior): single mode by name (--target/server.graph) with
top-level policy/queries previously used top-level; it now uses the per-graph
block and refuses boot if top-level is also populated. Bare-URI single mode is
unchanged. Loud, with migration text pointing at graphs.<name>.

- config: resolve_policy_file_for (policy sibling of query_entries_for, no
  top-level fallback) + populated_top_level_blocks for the coherence check.
- characterization tests (single-mode named -> per-graph; named + top-level ->
  bail; multi-mode top-level queries -> bail; CLI positional-URI -> top-level).
- docs: policy.md, server.md, cli-reference.md.

* docs: RFC-002 credentials keyed by server name (keychain/profile/env)

Reworks the RFC's credentials model: secrets are keyed by server name — OS
keychain `omnigraph:<server>` (preferred) -> a `[<server>]` profile in
`~/.omnigraph/credentials` -> `OMNIGRAPH_TOKEN[_<SERVER>]` env (CI), the
AWS/gh/kube model. `servers.<name>` is endpoint-only by default but may carry
an explicit, secret-free `auth: { token: { env|file|command|keychain } }`
source. The shipped `bearer_token_env` + `.env.omni` dotenv remain a legacy
compat path; no `credentials.yaml`.

* docs: RFC-002 — typed graph locator (storage/server/graph_id), not a uri string

Add §1.1: the resolved graph address is a typed GraphLocator
(Embedded{storage} | Remote{server, graph_id}), not a flat uri: String.
Diagnoses the string model's cost in the code today (~16 is_remote_uri forks,
TargetConfig can't express multi-server x multi-graph, the CLI bails on remote,
the ts SDK models baseUrl+graphId separately) and settles the YAML naming so
the key names the locus:

- storage: (embedded) — shipped uri: is a deprecated alias
- server: + graph_id: (remote) — graph_id defaults to the entry key
- storage xor server, reject both/neither (no silent ambiguity)

Kills the graphs:/graph: collision and the uri:-might-be-a-server ambiguity.
Updates the §1/§8 examples and the entry-shape notes to the new naming.

* Test: queries list must reject an unknown --target

queries list opens no graph URI, so unknown-graph validation does not ride
along on resolve_target_uri the way it does for every other command. The new
test reproduces the gap: with an unknown --target the command currently exits 0
and prints the (empty) top-level registry instead of erroring like the
URI-resolving commands do. Fails against current code; the fix follows.

* Validate the graph selection in queries list

Graph-existence validation was a side effect of URI resolution: every
URI-resolving command rejects an unknown --target via resolve_target_uri, but
queries list opens no URI, so query_entries_for(Some(unknown)) silently fell
back to the top-level registry and showed the wrong (or empty) catalog.

Make membership a property of the selection: add the fallible
resolve_graph_selection alongside the infallible query_entries_for (a known
name passes through, an unknown name errors with the same message as
resolve_target_uri, None stays anonymous), and validate the selection in
execute_queries_list. query_entries_for is unchanged — server boot's bare-URI
path still needs its None -> top-level arm.

* Surface policy-engine errors from stored-query invoke

The invoke handler mapped every authorize_request failure to 404 ('stored
query not found'), which collapsed the authorization decision (deny -> 403)
together with operational failures (no actor -> 401, Cedar evaluation error ->
500). A real policy-engine 500 was hidden as a missing query.

Separate the two concerns instead of sniffing the masked status. Extract
authorize() returning an Authz { Allowed, Denied(msg) } decision and reserve
Err for operational failures only; authorize_request becomes a thin wrapper
that maps Denied -> 403, so the 16 deny-as-403 callers are unchanged. The
invoke handler now matches the decision directly: a denial stays 404 (deny ==
missing, so the catalog can't be probed without the grant), while a 401/500
propagates with its true status.

500 is now a reachable outcome on POST /queries/{name}; document it in the
endpoint responses and regenerate openapi.json.

* Extract the named-graph/top-level coherence rule into one helper

The rule 'a named graph uses its own graphs.<name> block, so a populated
top-level block is a config error' lived inline in single-mode server boot.
Extract it to OmnigraphConfig::ensure_top_level_blocks_honored so the same
definition can be shared by the CLI selection gate (next commit) and the two
can't drift. Boot calls the helper; the message is reworded context-neutral
(drops 'serving') so it reads correctly from both boot and the CLI.

Behavior-preserving: multi-graph mode keeps its own unconditional check, and
single_mode_named_graph_rejects_top_level_blocks still passes.

* Test: queries validate/list must reject a named graph with a top-level block

Server boot refuses a config where a graph is selected by name yet a top-level
queries:/policy.file block is populated (the block would be silently ignored).
The CLI's queries validate/list resolve the same named selection but skip that
coherence check, so they give a false green / list the per-graph block. The new
test reproduces it: validate prints OK and list succeeds where boot would
refuse. Fails against current code; the fix follows.

* Enforce top-level coherence in the single CLI selection gate

queries validate validated graph membership only as a side effect of URI
resolution and queries list only via resolve_graph_selection's membership
check; neither applied the named-graph/top-level coherence rule server boot
enforces, so both gave a false green on a config boot refuses.

Fold ensure_top_level_blocks_honored into resolve_graph_selection so it is the
single gate that returns only valid + server-coherent selections, and route
resolve_selected_graph (queries validate) through it; queries list already
calls the gate. A named graph with a populated top-level block now errors in
both commands, matching boot. A positional URI stays anonymous (top-level
honored), so queries_validate_positional_uri_ignores_default_graph is
unaffected.

* docs: RFC-003 — MCP server surface for omnigraph-server

Detailed MCP-transport design for the stored-query/MCP work, building on the
shipped #128 registry. Corrects the draft against the branch head: the coarse
invoke_query gate + 404 denial-masking are already wired (server_invoke_query),
so per-query invoke_query scope (PolicyRequest has no query-name dimension yet)
is the real prerequisite; positions the doc as superseding rfc-001's MCP
transport (/mcp/tools+/mcp/invoke) and reconciles the shipped mcp.expose YAML
form and the schema-introspection non-goal; grounds the parity surface in the
actual omnigraph-ts package (13 tools with read/change ids, 2 resources).

* docs(config): clarify graph config boundaries

* fix(config): enforce graph-scoped policies and query validation

* fix(cli): require graph selection for scoped query registries

* fix(server): preserve named graph id in single mode policy

* fix(cli): share graph identity for policy resolution

* test(cli): cover policy tooling server graph selection

* fix(cli): honor server graph for policy tooling

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.

The Run state machine was removed in MR-771 (v0.4.0); `docs/dev/runs.md`
and `crates/omnigraph/tests/runs.rs` have since documented and tested the
direct-publish write path, so the "runs" name was misleading.

- git mv docs/dev/runs.md → docs/dev/writes.md (reframe H1 + intro;
  keep MR-771 history note)
- git mv crates/omnigraph/tests/runs.rs → tests/writes.rs (reframe header)
- repoint every runs.md / runs.rs reference across docs, AGENTS.md, and
  source comments
- fix four pre-existing broken `docs/runs.md` links (the file never lived
  at that path) to `docs/dev/writes.md`
- fix the stale v0.4.0 anchor to the live section

No behavior change: every source edit is a comment. Engine builds and the
renamed test passes 25/25; scripts/check-agents-md.sh passes.

The run-removal cleanup itself (run_registry.rs guard, __run__ prefix) is
deferred to MR-770.

feat: inline query strings in CLI and HTTP server (#110)
* feat(MR-656): inline query strings in CLI and HTTP server

CLI:
- Add -e / --query-string <STRING> to omnigraph read and omnigraph change
- Exactly one of --query, --query-string, --alias is required (3-way XOR)
- Empty --query-string is rejected with a clear error

HTTP:
- New POST /query (read-only, clean field names: query/name/params/branch/snapshot)
- Mutations on /query are rejected with 400 -- use POST /change instead
- ChangeRequest fields polished: query (alias query_source), name (alias query_name)
- POST /read and POST /change remain byte-compatible for existing clients

Tests:
- cli.rs: -e happy-path on read/change, mutex error vs --query, empty -e rejected
- system_local.rs: inline -e read and -e change exercise the local flow
- system_remote.rs: inline -e read/change over HTTP plus direct /query 200/400
- server.rs: /query 200, /query 400 on mutation, /change legacy field alias
- openapi.rs: new /query path, QueryRequest schema, ChangeRequest field-name polish

Docs: cli.md (-e examples), cli-reference.md (read/change rows), server.md (/query)

* feat(MR-656): rename read/change to query/mutate with deprecation signals

HTTP server:
- Add POST /mutate as canonical write endpoint (pairs with POST /query).
- Mark POST /read and POST /change as deprecated. Three-channel signal:
  * OpenAPI: `deprecated: true` on the operation (every codegen flags
    the generated SDK method).
  * RFC 9745: response `Deprecation: true` header on every response.
  * RFC 8288: response `Link: </successor>; rel="successor-version"`
    pointing at /query and /mutate respectively.
- Share business logic across /mutate and /change via run_mutate(); the
  /change wrapper is the only place that adds the deprecation headers.
- ChangeRequest field aliases (query_source/query_name) preserved.
- AliasCommand serde now accepts `query`/`mutate` alongside `read`/`change`.

CLI:
- Promote `omnigraph query` / `omnigraph mutate` to top-level canonical
  subcommands (clap visible_alias keeps `omnigraph read` / `omnigraph
  change` working forever).
- Promote `omnigraph lint` / `omnigraph check` to top-level (was nested
  under `omnigraph query lint`, which is now a deprecated argv shim that
  rewrites to the canonical form).
- Argv-level preprocessing prints a one-line deprecation warning to
  stderr when any legacy spelling is used. Canonical names are silent.

Tests:
- Server: /mutate works, /change emits Deprecation+Link headers, /read
  emits Deprecation+Link headers, /query carries no deprecation signal.
- OpenAPI: /read and /change flagged deprecated; /query and /mutate not.
- CLI: canonical `lint` matches deprecated `query lint` / `query check`
  output; `read` / `change` print deprecation warnings.

Docs:
- cli.md: new canonical examples; "Deprecated names" migration table.
- cli-reference.md: top-level table updated; aliases.<name>.command
  accepts both legacy and canonical spellings.
- server.md: endpoint inventory shows /query and /mutate as canonical
  and /read and /change as deprecated; dedicated section explains the
  three-channel deprecation signal.
- og-cheet-sheet.md: use new `omnigraph lint` / `omnigraph check`.
- openapi.json regenerated.

Migration is purely cosmetic — every deprecated form continues to work
indefinitely; only the spelling changes.

* fix(MR-656): address Devin Review findings on /query and /change

Two issues raised by Devin Review on PR #110:

1. `POST /query` mutation-rejection error pointed at the deprecated
   `/change` endpoint instead of the canonical `/mutate`. Fixed in
   three places: the runtime error message in `server_query`, the
   utoipa 400-response description, and the handler doc comment. The
   `QueryRequest` schema docstrings in `api.rs` got the same update so
   the openapi.json bodies match. Server and openapi tests updated.

2. `execute_change_remote` serialized `ChangeRequest` directly, which
   emits the new canonical field names `query` / `name` on the wire.
   `#[serde(alias = "query_source")]` only affects deserialization, so
   a newer CLI talking to an older server would have its `/change`
   POST body fail with "missing field: query_source". Fixed by
   extracting a `legacy_change_request_body` helper that hand-rolls
   the JSON with the legacy keys (`query_source` / `query_name`), the
   same byte-stable contract `execute_read_remote` already uses
   against `/read`. Added two unit tests on the helper to lock the
   wire shape in.

* docs(dev): RFC 001 — inline + stored queries, envelope, MCP

Tracked artifact consolidating the design across MR-656 (this branch),
MR-976 (Phase 1 envelope hardening parent, with MR-977/978/979/980
sub-issues), and MR-969 (stored queries + MCP).

Sections:

* Two paths, one engine — inline `/query` + `/mutate` (this PR) coexist
  with stored `/queries/{name}` (MR-969). Same `run_query` / `run_mutate`
  backend (the fold-in landed in the previous commit).
* Request envelope ("before") — Idempotency-Key, If-Match, X-Deadline,
  X-Trace-Id, expect, dry_run, fields. Phase 1 ships the load-bearing
  subset on `/mutate`.
* Response envelope ("after") — audit_id, snapshot_id, commit_id, stats,
  warnings. Closes the provenance loop today's `ChangeOutput` leaves
  open.
* `.gq` pragmas — `@description`, `@returns`, `@mcp`. Source-of-truth
  for the stored-query agent contract; no separate YAML registry.
* Multi-graph MCP — per-graph `/graphs/{id}/mcp/tools` + `/mcp/invoke`.
  Token binds to one graph by default; cross-graph agents loop.
* Cedar split — `read`/`change` for inline, `invoke_query` for stored.
  Operators deny ad-hoc for agent groups while keeping curated tool
  list open.
* Rejected alternatives — per-env override files, compiled bundles,
  tool-name prefixing across graphs, body-field graph dispatch.

Index entry added under "Active Implementation Plans" so future agents
land on the RFC before touching queries / mutations / envelope code.
`scripts/check-agents-md.sh` clean (35 links, 34 docs).

* docs(server): clarify why run_query lacks AppState parameter

run_mutate takes state for workload admission; run_query doesn't because
reads aren't admission-gated today. Mark the asymmetry as intentional and
flag the two future events that would grow the signature: Phase 1's
`expect: { max_rows_scanned: N }` budget (MR-976) or per-actor admission
extending to stored-read invocations (MR-969). Prevents the natural
"make these symmetrical" follow-up.

* refactor(server): run_query / run_mutate take &ResolvedActor

Replace `Option<Extension<ResolvedActor>>` in the helpers with
`Option<&ResolvedActor>`. Saves MR-969's stored-query handler from
wrapping a bare actor in axum's `Extension(...)` before calling.
Handler signatures (`server_query`, `server_read`, `server_mutate`,
`server_change`) keep `Option<Extension<ResolvedActor>>` because that
is what axum injects, and unwrap at the call site with
`actor.as_ref().map(|Extension(actor)| actor)`.

Net: -13/+10 LOC, 89/0 server tests pass.

* docs(releases): v0.6.0 — describe inline + canonical-named queries (MR-656)

Extend the v0.6.0 release notes to cover the third piece of work landing
alongside the graph terminology rename and multi-graph server mode:
canonical-named `POST /query` and `POST /mutate` endpoints, the CLI's
new `-e/--query-string` flag, the top-level promotion of `lint` /
`check`, and the three-channel deprecation signal on `/read` and
`/change` (OpenAPI `deprecated: true` + RFC 9745 + RFC 8288).

Additions:

* Top blurb: "Two pieces" -> "Three pieces" with a bullet describing
  the rename + inline flow.
* Breaking Changes: new "Query / mutation rename" subsection covering
  the `ChangeRequest` field rename (with the back-compat serde aliases
  and the CLI's `legacy_change_request_body` byte-stable wire helper)
  and the `omnigraph query lint` -> `omnigraph lint` move.
* New: 5 bullets — the two endpoints, the CLI subcommands, the `-e`
  flag, the deprecation signal channels, the widened `aliases.<name>.command`
  vocabulary.
* User Impact: one bullet making explicit that the rename is cosmetic
  on the client side and migration is voluntary.
* Documentation: pointers to the updated `server.md` / `cli.md` /
  `cli-reference.md` and the new `docs/dev/rfc-001-queries-envelope-mcp.md`.

+15/-1 lines. `./scripts/check-agents-md.sh` clean.

* refactor(cli): demote `check` from visible_alias to deprecation shim

`omnigraph check` was a clap `visible_alias` on `lint`, advertised in
`--help` as an equivalent canonical name. Per MR-981 §6 (long-form
flags as canonical, short forms as visible aliases), visible aliases
on subcommand names hurt agent CX: agents emit either spelling
depending on training-data drift, and there's no length signal
pointing at the canonical name.

Changes:

* Remove `#[command(visible_alias = "check")]` from the `Lint` variant.
  `omnigraph --help` now shows only `lint`.
* Add bare `check` to `rewrite_deprecated_argv` so `omnigraph check
  <args>` still works — it rewrites to `omnigraph lint <args>` and
  emits a one-line stderr deprecation warning, matching the existing
  pattern for `read` / `change` / `query lint` / `query check`.
* Fix the nested `query check` shim to substitute `check` -> `lint` in
  the rewritten argv (previously it relied on `check` being a
  visible_alias to reach the `Lint` variant).
* New test `deprecated_check_top_level_rewrites_to_lint` covers: bare
  `check` produces identical stdout to `lint`, emits the deprecation
  warning, and `check` does NOT appear as an alias in `omnigraph
  --help`.
* Release notes updated to reflect the deprecation-shim treatment and
  cross-reference MR-981 §6 reasoning.

Cargo / Go users typing `check` still work indefinitely; one stderr
nudge per invocation teaches the canonical name. Agents see only
`lint` in `--help --json` so they emit one canonical form.

67/0 omnigraph-cli tests pass; 39 workspace test suites green.
