Merge branch 'main' into ragnorc/omnigraph-mcp-crate
Folds in v0.7.1 (release #290 + optimize/write-path/internal-table-compaction fixes #288/#291/#297) under the MCP branch. Conflict resolutions (5 files): - crates/omnigraph-server/Cargo.toml: take main's 0.7.1 path-dep constraints; keep our omnigraph-mcp dep (bumped to 0.7.1) + http dep. - crates/omnigraph-server/src/handlers.rs: keep our server_list_queries doc-comment (exposed @mcp(expose) subset, invoke_query-gated) — it supersedes main's pre-@mcp(expose) text, since this branch adds the per-query expose flag. - docs/user/operations/server.md: keep our GET /queries description (invoke_query gate + @mcp(expose) exposure) over main's read-gated/list-all text. - docs/dev/index.md: keep both in-flight RFC rows; renumber this branch's tenancy RFC 013 -> 014 (rfc-014-tenancy-cells.md) since main now owns RFC-013 (rfc-013-write-path-latency.md). Title + index link updated; link-check green. - openapi.json: regenerated from merged source (OMNIGRAPH_UPDATE_OPENAPI=1) — now info.version 0.7.1 with our invoke_query/@mcp schema. Coherence: omnigraph-mcp bumped 0.7.0 -> 0.7.1 to match the workspace; Cargo.lock updated. cargo build --workspace green; server/mcp/api-types/compiler suites green (schema_routes.rs reopen-after-apply flakes under parallel IO on a near-full disk, passes single-threaded — a pre-existing main test, unchanged by the merge).

# User Docs Coherence Ledger
|
||||
|
||||
**Last review:** 2026-06-20 (against 0.7.1)
|
||||
**Status:** all open findings resolved — living ledger for future audits.
|
||||
|
||||
This page tracks stale or incoherent user-doc claims found during broad docs
|
||||
reviews. Findings are validated against current **code/behavior**, not just
|
||||
cross-doc consistency. Record new findings as they surface; mark them resolved
|
||||
(with the fixing commit) once the public pages are corrected.
|
||||
|
||||
## Resolved — 2026-06-20 docs/user coherence sweep
|
||||
|
||||
Every finding from the 2026-06-20 review was validated (all reproduced) and
|
||||
fixed. Branch `docs/user-coherence-0-7-1`.
|
||||
|
||||
| Pri | Finding | Resolution |
|
||||
|---|---|---|
|
||||
| P1 | `cluster apply` documented as catalog-only / "Stage 3A" with graph+schema deferred — in both `cli/reference.md` and the shipped CLI help (`cli.rs`) | Rewrote both to describe the real converge behavior (creates graphs, applies schema with soft drops, writes catalog, executes approved deletes in one ordered run); `deferred` now means the genuinely-unsupported case (standalone schema delete). |
|
||||
| P1 | Stored-query exposure had two contracts: `server.md` documented a per-query `mcp:{expose:false}` knob; cluster docs said all queries are listed | Confirmed in code: cluster registry has no expose field (`QueryConfig`), boot bridge hardcodes `expose: true` (`omnigraph-server` settings), no GQ-level annotation. Removed the knob from `server.md`; documented "every applied query is listed; per-query exposure may become a Cedar-policy decision later". |
|
||||
| P1 | The same stale "`mcp.expose == true` subset" contract lived in the **OpenAPI surface**: utoipa annotations (`handlers.rs:1029,1037`, `omnigraph-api-types/src/lib.rs:404`) drove `openapi.json` (Greptile catch on #293) | Updated the three Rust doc-comment/annotation strings to "every stored query" and regenerated `openapi.json` (`OMNIGRAPH_UPDATE_OPENAPI=1`); drift test green. Same-change per AGENTS.md rule 4. |
|
||||
| P2 | `schema/index.md` claimed `allow_data_loss` honored "uniformly across transports" incl. HTTP `POST /schema/apply` | Scoped to the direct/embedded path; added that cluster-managed graphs evolve via `cluster apply` (soft drops only) and the HTTP route is 409-disabled for cluster serving. |
|
||||
| P2 | `/load` missing from admission / body-limit / rate-limit / manifest-conflict prose (named `/ingest` only); constants called it "Ingest body limit" | Documented `/load` as canonical everywhere with `/ingest` as the deprecated alias; renamed the constant to "Load (bulk-write) body limit". |
|
||||
| P2 | CLI "Bearer token resolution" section listed removed `omnigraph.yaml` keys (`graphs.<name>.bearer_token_env`, `auth.env_file`) | Replaced with a pointer to the keyed-credential model (`OMNIGRAPH_TOKEN_<NAME>` → `~/.omnigraph/credentials` → `OMNIGRAPH_BEARER_TOKEN`); no plaintext-in-config path. |
|
||||
| P2 | Flat route names in a cluster-only server (`POST /query`, `POST /mutate`, `GET /queries`, `POST /queries/{name}`) | Added a one-line note that the per-graph subsections use shorthand under `/graphs/{id}/…`; the endpoint table is already fully qualified. |
|
||||
| — | `version` printed `omnigraph 0.3.x` | → `0.7.x`. |
|
||||
| — | `search/indexes.md` used deprecated `ingest --mode merge` | → `load --mode merge`. |
|
||||
| — | `config.md` `deferred` disposition described as "graph/schema change, later phase" | → "an unsupported change (e.g. standalone schema delete)". |
|
||||
| — | Stale stage labels (`Stage 3A`, `Stage 2C`, `Stage 1`) in active reference docs | Removed / reworded to plain language; release notes keep history. |
|
||||
|
||||
## Open — surfaced 2026-06-20, not yet fixed
|
||||
|
||||
- **Stale "config-only apply" / "Stage 3A" comments in `omnigraph-cluster`
|
||||
source** (internal rustdoc, not user docs — out of scope for the docs sweep
|
||||
above): `src/types.rs:147` ("Applied changes execute (config-only query/policy
|
||||
catalog writes)"), `src/types.rs:265` ("Output of config-only cluster apply"),
|
||||
`src/diff.rs:256`, and `src/tests.rs:1129` ("config-only apply (Stage 3A)").
|
||||
Apply now also runs graph creates, schema applies, and approved deletes
|
||||
(`diff.rs:411` `GraphCreate` / `SchemaApply`; the Stage-4 create/schema/delete
|
||||
executors + tests `apply_creates_graph_and_unblocks_dependents`,
|
||||
`apply_schema_update_and_dependent_query_in_one_run`,
|
||||
`apply_blocks_graph_delete_without_approval`). Update these comments in a
|
||||
cluster-crate change.
|
||||
- **Cross-repo drift from this sweep** (separate repos):
|
||||
- `omnigraph-ts` SDK — its generated `spec/openapi.json` +
|
||||
`packages/sdk/src/generated/types.gen.ts` still describe the `GET /queries`
|
||||
catalog as the `mcp.expose` subset. **No hand-fix:** the SDK's
|
||||
`scripts/sync-spec.ts` pulls openapi.json from a *tagged* omnigraph release
|
||||
(`/omnigraph/v{version}/openapi.json`), and the catalog fix landed on main
|
||||
*after* the v0.7.1 tag — so it is in no tag yet and a hand-edit would be
|
||||
overwritten on the next sync. It flows in automatically when the SDK bumps
|
||||
to a tag containing the fix (v0.7.2+). Tracked, not actioned.
|
||||
- `omnigraph-cookbooks/docs/best-practices.md` `bearer_token_env` chain —
|
||||
**RESOLVED** by omnigraph-cookbooks PR #26 (2026-06-21), which deleted
|
||||
`docs/best-practices.md` as part of the 0.7 restructure; the stale chain
|
||||
survives nowhere on `main`.
|
||||
|
||||
## Verification checklist (re-run on the next docs audit)
|
||||
|
||||
```bash
|
||||
rg -n "Stage [0-9]|graph/schema changes are deferred|reserved for later stages" docs/user crates/omnigraph-cli/src/cli.rs
|
||||
rg -n "POST /query|POST /mutate|GET /queries|POST /queries/\{name\}|POST /schema/apply" docs/user

rg -n "0\.3\.x|bearer_token_env|auth\.env_file" docs/user
|
||||
rg -n "expose: false|mcp\.expose" docs/user
|
||||
```
|
||||
|
||||
Expected: active user docs have no matches for stale phrases, or the remaining
|
||||
matches are explicitly marked as deprecated aliases, "no longer exist" notes, or
|
||||
route shorthand disclaimed relative to `/graphs/{id}`. Release notes are allowed
|
||||
to preserve historical behavior.

- **Assert a cost budget, not just a result.** For a read/open path, assert the number of `Dataset::open` calls (or object-store ops) a warm query performs, and that it does not grow with commit count. The reference is LanceDB's IO-counted tests, which assert a cached read costs 0-1 IO and carry a named regression test against "a list call on every subsequent query."

- **Test at history depth.** Build a fixture with many *commits* (not many rows) and assert warm-read cost is flat across depths. A shallow fixture cannot catch an O(commits) cost.

- **Use the shared harness, and gate each term on the backend where it manifests.** `helpers::cost` (`measure`/`IoCounts`/`assert_flat`/`local_graph`/`s3_graph`) is the one place the `IOTracker`/task-local plumbing lives — consume it, don't duplicate it. The write path has *two distinct* depth terms that split cleanly across backends, and conflating them is a real trap (the local data-table read count grows with depth too, but for a different reason — the merge-insert/RI scan reading O(depth) *fragments*, reduced by compaction, not by the opener): (1) the **internal-table** scan term (`__manifest`/`_graph_commits` fragment scans) reproduces on **any** backend including local FS, so `write_cost.rs` gates it on local every-PR; (2) the **data-table opener** term (latest-version resolution) is a per-object-store-RPC phenomenon — local-FS resolves latest with one cheap `read_dir` regardless of the opener used, so the namespace-vs-direct difference is **invisible on local** and only shows on a real object store (per-version GETs), gated by the bucket-gated `write_cost_s3.rs`. Same harness, different fixture; each term asserted where it actually appears.

cluster-apply crash loops, branch-merge OOM on embedding tables), one CLI

catalog-metadata improvement, and a warm-read performance fix. No breaking

and planned cleanly but failed at run time with `No field named reponame.
|
||||
Column names are case sensitive.` The identifier's case was destroyed at two
|
||||
engine→Lance boundaries: the read-filter pushdown built the column with a
|
||||
case-normalizing constructor, and the pending-batch mutation scan re-parsed
|
||||
the predicate through a normalizing SQL context. Both now preserve case (the
|
||||
read path uses a case-preserving column reference; the pending scan disables
|
||||
SQL identifier normalization), so camelCase fields work consistently in read
|
||||
and write predicates and a camelCase `@index` equality still routes to the
|
||||
scalar index. The fix is correct-by-construction rather than a per-query
|
||||
guard; a regression test pins index routing so a silent full-scan fallback
|
||||
can't slip back in.
|
||||
|
||||
- **`cluster apply` no longer crash-loops a booting server (#284).** Applying a
|
||||
schema change while a graph had non-main (agent/review) branches, or a
|
||||
migration that needed a backfill, could throw a freshly-booting
|
||||
`omnigraph-server --cluster` into an unescapable crash loop. Neither input is
|
||||
an engine bug — the engine rejects both cleanly and before moving any graph
|
||||
state — but `cluster apply` wrote a recovery sidecar before calling the
|
||||
engine and left it in place on the clean rejection, and the server refuses to
|
||||
boot while a sidecar is pending. The asymmetric-cleanup path is fixed so a
|
||||
pre-movement rejection leaves no stale sidecar, breaking the loop.
|
||||
|
||||
- **Branch-merge fast-forward no longer OOMs on embedding tables (#277).** A
|
||||
branch→main fast-forward merge of a forked, embedding-bearing table
|
||||
re-derived the whole branch through a single Lance `merge_insert` — a
|
||||
full-outer hash join over the entire delta — which exhausted the DataFusion
|
||||
memory pool on high-dimensional embeddings (e.g. 8k rows × 3072-dim) and hung
|
||||
or failed the merge. New rows now stream through `stage_append` (no hash
|
||||
join), only genuinely-changed rows are upserted, embeddings are no longer
|
||||
stringified to diff them, and index coverage defers to the reconciler, so a
|
||||
fast-forward merge completes in bounded work. The three-way merge path is
|
||||
unchanged.
|
||||
|
||||
## Improvements
|
||||
|
||||
- **`omnigraph queries list` surfaces stored-query `@description` /
|
||||
`@instruction` (#280).** The CLI now shows a stored query's catalog metadata —
|
||||
what it does and how to invoke it — in both human and `--json` output,
|
||||
matching what `GET /queries` already returned. Previously both fields were
|
||||
silently dropped on the CLI side.
|
||||
|
||||
- **Warm reads no longer pay an O(history) metadata tax (#268).** Warm reads
|
||||
used to re-derive per-query metadata (coordinator re-open, `__manifest` +
|
||||
commit-graph re-scans, per-table re-open, double schema validation) on a cost
|
||||
that scaled with commit history and never warmed up. A warm same-branch read
|
||||
now does one cheap version probe, one schema read, and zero table opens on a
|
||||
warm repeat (warm coordinator reuse, open-by-location+version, validate-once,
|
||||
held `Dataset` handles + one shared Lance `Session` per graph). This also
|
||||
closes a commit-DAG fork where a same-branch write after an external commit
|
||||
could append off a stale cached head.
|
||||

- Compacts every node + edge table on `main`, then reindexes them, then **publishes the resulting version to the `__manifest`** so the manifest's recorded version tracks the compacted-and-reindexed state. Reads pin the manifest version, so without this publish the work would be invisible to readers *and* would break the version precondition of the next schema apply / strict update/delete ("stale view … refresh and retry"). The publish advances the graph version (a system-attributed commit) only for tables that actually changed.
|
||||
- Rewrites small fragments into fewer large ones; old fragments remain reachable via older versions until `cleanup` runs.
|
||||
- **Also compacts the internal system tables** `__manifest`, `_graph_commits`, and `_graph_commit_actors` (RFC-013 step 2), which accumulate one fragment per commit (the actor table only on the authenticated write path, where every commit carries an actor) and otherwise make every write's metadata scan grow with history. These take a simpler path than data tables: they are not `__manifest`-tracked (readers open them at their latest version), so compaction just advances their version in place — **no manifest publish and no recovery sidecar**. (The sidecar-free property is not because it is one commit — `compact_files` can emit a `ReserveFragments` commit before the `Rewrite`, and the auto-cleanup strip below is a further commit — but because every one of those commits is content-preserving and the table is read at its latest version, so a crash at any point leaves it readable and content-identical and the next `optimize` re-plans.) They appear in the returned stats under `table_key` `"__manifest"` / `"_graph_commits"` / `"_graph_commit_actors"` (the latter two only when present). They are **not yet covered by `cleanup`**, so their version chain still grows until the cleanup half lands (it requires a cleanup-resurrection safeguard first); run `optimize` on a cadence to keep per-write metadata scans flat.
|
||||
- **`optimize` is non-destructive by construction — it never garbage-collects versions, on any table (data or internal).** Compaction rewrites fragments and advances the version; old versions stay reachable until you run `cleanup`. This holds even for a graph created by an older binary that stored an on-by-default Lance `auto_cleanup` hook: `compact_files` / `optimize_indices` commit with the hook enabled and expose no skip override, so before compacting **any** table `optimize` strips its stale `lance.auto_cleanup.*` config first, so Lance's commit-time GC hook cannot fire and silently prune `__manifest`-pinned versions. (Graphs created by current binaries store no such config; the strip is the upgrade-path safety net.) The internal-table path additionally tolerates a concurrent live writer: it runs a **bounded** rebase-and-retry, so transient contention does not fail the operator's `optimize` or the live write — but sustained contention past the retry budget surfaces a loud conflict error rather than looping forever (bounded and observable, not a silent give-up). The data-table path holds the per-table write queue while it compacts, so it does not contend with mutations on that table in the first place.
|
||||
- **Reindex (index coverage maintenance).** A scalar/FTS/vector index only covers the fragments it was built over. Rows appended after the index was built (e.g. by `load --mode merge`, whose commit does not rebuild an already-existing index) are scanned unindexed, and compaction itself rewrites fragments out of an index's coverage. `optimize` runs Lance's incremental `optimize_indices` after compaction to fold those fragments back in (a delta merge, not a full retrain), restoring full coverage so equality/range/traversal predicates stay index-accelerated. This is why a table with **no compaction work but stale index coverage still commits** a new version under `optimize`. Run `optimize` on a cadence at least as frequent as your freshness window so recently-loaded rows do not linger in the unindexed flat-scan tail.
|
||||
- **Create declared-but-missing indexes (the index reconciler).** `@index`/`@key` declares intent; `schema apply` records it but builds nothing, and `load`/`mutate` defer a column that cannot be built yet (a `Vector` column with no trainable vectors). `optimize` materializes any such declared-but-unbuilt index over the compacted layout — so it is the convergence path for an `@index` added after data exists, or a vector index whose embeddings arrived via a later `embed`. A column still not buildable (no vectors yet) is reported on the table's stat as `pending_indexes` (visible in `--json`), not treated as a failure; the next `optimize` retries. So `optimize` is the single operator-facing index reconciler: it compacts, restores coverage, **and** builds declared-but-missing indexes.
|
||||
- Each table's compact→reindex→publish serializes with concurrent mutations on the same table. A crash mid-operation is recovered automatically on the next open (both compaction and reindex are content-preserving, so roll-forward is always safe).
