The required contexts therefore never matched any reported check and sat permanently pending. - The workflow was also path-filtered to CODEOWNERS files, so it didn't even run for most PRs. Net effect: with both required checks unsatisfiable, every PR could only land via admin override (e.g. #140). Fixes: - A: drop the `paths:` filter so the workflow runs on every PR and both required contexts always report. - name fix: point branch-protection.json at the actual job names verbatim, and add a doc note that the contexts must equal the job `name:` values. - B: the `drift` job now re-renders and, on same-repo PRs, auto-commits the regenerated artifacts back to the branch (mirrors the openapi.json job in ci.yml); forks / manual runs strict-check instead. Contributors no longer run the script by hand. - D: render-codeowners.py also generates a "who owns what" path->owners + roles table spliced into docs/dev/codeowners.md between markers, so the human-readable view never drifts. Idempotent; CODEOWNERS output unchanged. - docs: correct the stale `enforce_admins: true` line (JSON and live are false). NOTE: the branch-protection.json change only takes effect after an admin runs `./scripts/apply-branch-protection.sh` (deliberate manual step, per docs/dev/branch-protection.md). Until then `main` still requires the old mismatched contexts, so this PR itself needs an admin-override merge — the last one that should be necessary.

Maintainers keep a separate internal process and are exempt from the intake gates; everyone stays bound by review, CODEOWNERS, and branch protection. Model: - Issues = problem reports only (bug form + config.yml redirects ideas to Discussions and disables blank issues). - Discussions = ideas + RFC incubation. - RFCs = anyone (incl. external) authors docs/rfcs/NNNN-*.md; a maintainer merging it is acceptance. Distinct from the maintainer-internal docs/dev/rfc-00N-* track. - PRs = link an `accepted` issue or accepted RFC, or use the trivial fast-lane (typos/docs/deps). Enforced softly to start (template + review). Adds GOVERNANCE.md, rewrites CONTRIBUTING.md, adds docs/rfcs/ (README + template), .github issue/PR/discussion templates. Wires docs/rfcs/ into the doc-link checker (excluded like releases; linked from docs/dev/index.md).

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 --- crates/omnigraph/src/db/manifest.rs | 16 ++++ .../omnigraph/src/db/manifest/migrations.rs | 55 ++++++++++++- crates/omnigraph/src/db/manifest/tests.rs | 74 +++++++++++++++++ crates/omnigraph/src/db/mod.rs | 7 +- crates/omnigraph/src/db/omnigraph.rs | 81 +++++++++++++++---- .../src/db/omnigraph/schema_apply.rs | 10 +-- crates/omnigraph/src/db/run_registry.rs | 16 ---- crates/omnigraph/src/exec/merge.rs | 4 +- crates/omnigraph/src/exec/mod.rs | 2 +- crates/omnigraph/tests/writes.rs | 33 ++++---- docs/dev/writes.md | 18 +++-- docs/releases/v0.6.1.md | 2 + docs/user/audit.md | 2 +- docs/user/branches-commits.md | 10 +-- docs/user/constants.md | 6 +- docs/user/storage.md | 5 +- 16 files changed, 269 insertions(+), 72 deletions(-) delete mode 100644 crates/omnigraph/src/db/run_registry.rs diff --git a/crates/omnigraph/src/db/manifest.rs b/crates/omnigraph/src/db/manifest.rs index 7fcf7de..3b2886f 100644 --- a/crates/omnigraph/src/db/manifest.rs +++ b/crates/omnigraph/src/db/manifest.rs @@ -48,6 +48,22 @@ const OBJECT_TYPE_TABLE_VERSION: &str = "table_version"; const OBJECT_TYPE_TABLE_TOMBSTONE: &str = "table_tombstone"; const TABLE_VERSION_MANAGEMENT_KEY: &str = "table_version_management"; +/// Apply pending internal-schema migrations against `__manifest` on the +/// open-for-write path, independent of a publish. +/// +/// `Omnigraph::open(ReadWrite)` calls this before the coordinator reads branch +/// state, so branch-observing code (`branch_list`, the schema-apply +/// blocking-branch checks) sees the post-migration graph.

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. --- AGENTS.md | 4 +- crates/omnigraph/src/db/manifest.rs | 2 +- crates/omnigraph/src/db/manifest/recovery.rs | 187 +++++++++----- crates/omnigraph/src/db/omnigraph/optimize.rs | 234 +++++++++++++++--- crates/omnigraph/tests/composite_flow.rs | 69 ++++-- crates/omnigraph/tests/end_to_end.rs | 84 +++++++ crates/omnigraph/tests/failpoints.rs | 122 ++++++++- crates/omnigraph/tests/helpers/recovery.rs | 3 + crates/omnigraph/tests/maintenance.rs | 124 +++++++++- crates/omnigraph/tests/recovery.rs | 91 +++++++ docs/dev/testing.md | 6 +- docs/dev/writes.md | 17 +- docs/user/branches-commits.md | 2 +- docs/user/maintenance.md | 6 +- docs/user/storage.md | 2 +- 15 files changed, 816 insertions(+), 137 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index b876749..3f5b711 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -236,8 +236,8 @@ omnigraph policy explain --actor act-alice --action change --branch main | Columnar storage on object store | ✅ Arrow/Lance | URI normalization, S3 env-var plumbing | | Per-dataset versioning + time travel | ✅ | `snapshot_at_version`, `entity_at`, snapshot-pinned reads across many tables | | Per-dataset branches | ✅ | **Graph-level** branches (atomic across all sub-tables), lazy fork, system branch filtering | -| Atomic single-dataset commits | ✅ | **Multi-table publish via three layers**, NOT a single Lance primitive: (1) per-table Lance `commit_staged` for the data write, (2) `__manifest` row-level CAS via `ManifestBatchPublisher` for cross-table ordering, (3) the open-time recovery sweep for the residual gap between (1) and (2).

Reopen the graph to run the recovery sweep, then re-run `optimize`. (Recovery roll-back now publishes its restored version, so a recovered graph always satisfies `manifest == Lance HEAD` going in; there is no leftover drift for `optimize` to interpret.) - Bounded by `OMNIGRAPH_MAINTENANCE_CONCURRENCY` (default 8). - Returns `[TableOptimizeStats { table_key, fragments_removed, fragments_added, committed, skipped }]`. - **Blob tables are skipped.** A table that declares any `Blob` property is not compacted: it is reported with `skipped: Some(BlobColumnsUnsupportedByLance)` (and logged via `tracing::warn`) instead of compacted, and the rest of the sweep proceeds normally. The current Lance `compact_files` mis-decodes blob-v2 columns under its forced `BlobHandling::AllBinary` read; **reads and writes are unaffected** — only compaction is. This is gated by `LANCE_SUPPORTS_BLOB_COMPACTION` (`db/omnigraph/optimize.rs`) and removed when the upstream Lance fix lands (see [docs/dev/lance.md](../dev/lance.md)).

The Sarah/Bob test.** If one operator changes schema / queries / policies / UI / pipelines / aliases, another operator (or their agent) must learn *what the deployment is and what changed* from **one source, one history, one diff**. Fragmentation across separate mechanisms is the failure the whole design exists to eliminate. Every other axiom is in service of passing this test. + +--- + +## Core axioms (what the design is based on) + +**1. The cluster is the unit of declarative state.** Not the graph (policies, queries, UI, and pipelines cross-cut graphs; "which graphs exist" has no per-graph home), not the fleet (the next scope up — named and deferred). The cluster is what two operators collaborate over; a graph is a *resource within* it. + +**2. Two sources of truth, for two different questions — config for *intent*, state for *deployed reality*.** The version-controlled **config** (a set of files in one folder) is the source of truth for what the cluster *should be*. The **state ledger** is the source of truth for what *is* currently deployed. Change flows one way only: you edit config and `apply` converges the cluster (**code → cluster**, never edit-the-cluster-and-call-it-intent). But "what exists right now" is read from **state**, not re-derived from the world on every command. `plan` is the diff between the two. + +**3. Declarative, not imperative.** You describe the desired end state; the reconciler computes the steps. No runtime mutation API that makes the running system the place *intent* lives. + +**4. As-code is structural, not stylistic (the recursion argument).** Code is the base case; modeling the definition *as data* (a meta-graph describing graphs) recurses with no base case. Config must live **outside** the running system so it is reviewable (PRs), reproducible (clone + apply), diffable as text, and editable by an agent — without the system having to describe itself. + +<!-- Audit fix: JSON keeps the first backend Terraform-shaped and inspectable. +Lance datasets are future optimization, not the baseline state format. --> +**5. The Terraform model: config / state / reconcile — and state is an authoritative, locked ledger.** Config (as code) = desired truth. **State = the authoritative record of what has been applied**, held in a **backend** — the cluster's own object-store backend *or* a separate cloud store, the operator's choice, exactly like a Terraform backend. The baseline representation is JSON documents (`state.json`, status/approval/recovery JSON records) protected by backend lock/CAS, not Lance control-plane tables. State is **locked** during apply so two operators cannot converge concurrently. `validate` parses and schema-checks desired config; `plan` = `diff(config, state)` as a structured artifact with resource digests, dependency edges, state observations, proposed changes, blast radius, and approval gates; `apply` converges the cluster from an accepted fresh plan and **updates state**, and does not acknowledge success until state has recorded the result. A cluster-hosted JSON backend is still a separate state CAS step from graph Lance manifest moves; failures surface a repair/import condition instead of being described as cross-object all-or-nothing. A future Lance-backed state backend or cluster manifest publisher is optional and must earn its complexity by needing row-level queryability/history or tighter publish fencing. Because OmniGraph's running cluster is self-describing (manifests, commit logs), state is *reconstructable* by import/refresh if lost — its edge over opaque-cloud Terraform — but it is **treated as the source of truth for current reality, not casually regenerated**. The one slice that can never be reconstructed (who approved an irreversible apply) lives in the durable audit ledger; state references it (axiom 11). + +**6. The control plane reconciles definition, not data — across two data-plane seams.** Definition — schema, policies, queries, UI, bindings, aliases, ETL **pipelines**, embeddings config, and the set of graphs — is reconciled. Data — rows, edges, vectors — is data-plane content, versioned by the commit DAG and produced by `load` / `mutate` and **pipeline execution**, sitting **outside** the reconcile loop. Exactly two definition kinds *trigger* a data-plane effect without owning data: **schema** (a migration conforms existing rows; `plan` previews its impact) and **ETL pipelines** (their execution ingests external data). The loop converges their *definitions*; the data they produce is never what it reconciles. + +**7. Operated by agent (agent-as-controller).** An agent authors config changes and drives reconciliation as an authenticated actor, subject to policy and approval gates — no human state-management burden. This fuses Terraform's as-code config with Kubernetes' continuous reconciliation. + +--- + +## Derived rules (consequences of the axioms) + +**8. The reversibility gradient gates apply — including drift correction.** Irreversible / data-loss operations (drop a graph, hard-drop schema data, a pipeline that overwrites) and compatibility-narrowing migrations (for example, future validated enum narrowing) are gated; reversible ones (recolor a dashboard) are not. The gate is keyed to physics, not to who operates it, and a reconciler "just fixing drift" is never an exception. + +**9. Atomicity and referential integrity are plan-time, not runtime.** `ApplyGroup` is the atomicity unit; cross-resource references *force* grouping (mandatory, not opt-in); references use typed resource/provider addresses (`graph.knowledge`, `query.knowledge.find_experts`, `provider.source.github_org`) so the planner can reject wrong-kind or missing targets before apply — bare names in a kind-fixed field are accepted shorthand and normalized to the typed address (fix 2026-06-08), while a kind-ambiguous value (e.g. `source: github`) is rejected; a reference to a missing or being-removed resource is a fail-closed `plan` error, not a deferred runtime failure. + +**10. Secrets live in a `.env` file; connection/identity is per-operator.** The committed cluster config carries **no secret values** — only `${NAME}` references. The values (embedding API keys, pipeline **source credentials**, per-deployment settings) live in a separate **`.env` file** — which is gitignored and supplied per deployment, never committed. Separately, an operator's own connection (which cluster, which token) is the per-operator layer, distinct from both the shared config and its `.env` file. + +**11. Approvals and audit live in a durable ledger, not inline in state.** State *references* the audit record by id. In the baseline, that ledger is append-only JSON records in the state backend; a future Lance table is an implementation option, not a requirement. This keeps the bulk of state reconstructable and keeps approval facts — "who authorized this irreversible apply" — where loss is impossible. + +**12. State lives in a backend and is locked.** The state ledger is stored in a configurable backend — the cluster's own backend, or a separate cloud store — and `plan`/`apply` acquire a **state lock** first, so concurrent applies serialize instead of racing. (Generalizes the existing `__schema_apply_lock__` from schema scope to cluster scope.) The backend choice is part of the safety model: the first backend should be JSON plus object-store lock/CAS; any Lance-backed state backend needs its own RFC-level proof that the table semantics are worth the control-plane complexity. + +**13. Pipelines are definition; their execution is data-plane.** An ETL pipeline (external source → transform → target graph) is **declared in config and reconciled like any resource**; *running* it produces ordinary data-plane writes (`load`/`mutate`) outside the reconcile loop. `apply` converges the pipeline's *definition* (create / update / delete / schedule); the rows it ingests are never reconciled. A fan-out run over several graphs is statusful rather than magically atomic: each target records commit id, status, retryability, and idempotency key unless the pipeline explicitly uses a branch/merge protocol that can fence the whole target set. Source credentials are secret references (axiom 10). + +<!-- Audit fix: current shipped behavior still has mcp.expose and coarse +invoke_query. This axiom is the target control-plane rule, not a statement +about today's server catalog. --> +**14. Exposure is a policy decision, not a config flag.** Target design: which stored queries (and the tools/dashboards built on them) an actor may **list or invoke** is decided by the policy layer (Cedar: `invoke_query` + catalog visibility), not by a per-query `expose:` boolean. The registry only says a query *exists* (name → file); **policy says who may see and run it**, so the MCP catalog (`GET /queries`) becomes each actor's policy-permitted set. This supersedes the engine's current `mcp.expose` flag only after per-query `invoke_query` scope and Cedar-filtered catalog listing land; until then, proposals must state the compatibility bridge to today's `mcp.expose` + coarse invocation gate. + +--- + +## The one-line compression + +**One cluster; config (a folder of files) is desired truth and a locked state ledger in a backend is deployed truth; `plan` diffs them, `apply` converges the cluster and updates state, an agent drives the loop — reconciling the cluster's *definition* (schema, policies, queries, UI, pipelines, …) and never its data — so any operator sees the whole system and its history from one place.** + +--- + +## How to use this file + +- **Reviewing a proposal:** walk axioms 0–14; any conflict is the burden of the proposer to justify.

The full set of config assets (incl. **aliases**, **embeddings**) is enumerated below. + +--- + +## The problem (the Sarah/Bob test) + +Two operators, Sarah and Bob, administer the same OmniGraph deployment. Sarah adds new queries, changes a schema, adds a dashboard, updates policies, and wires in a new data feed. + +**How does Bob find out?** + +Today he can't — not cleanly. Sarah's changes land in many different places via many different mechanisms: + +- schema → the schema-apply path, accepted state in `_schema.pg`, `_schema.ir.json`, `__schema_state.json`, and table versions in the graph manifest +- queries → `.gq` files passed per request or resolved through CLI query roots / aliases; not durable cluster state +- policies → `policy.file` in `omnigraph.yaml`, pointing at Cedar/YAML files that are usually GitOps'd externally +- aliases → CLI sugar in each operator's `omnigraph.yaml` +- external data → ad-hoc `load`/`ingest` scripts, cron jobs, glue code that lives nowhere durable +- UI → undefined + +There is no single diff that spans them, no single change record attributed to Sarah, no one place Bob (or Bob's agent) reads to answer "what is this deployment, and what changed?" The state is **fragmented**, and fragmentation is hostile to the one thing an agent must do: reason over the system *as a whole*. + +A design passes only if it answers the Sarah/Bob test directly. + +--- + +## Thesis + +The unit of declarative state is the **cluster** (the deployment), described by **a single config, as code, in version control**, operated by an **agent** through a plan/apply/reconcile loop against an authoritative state ledger. + +Every surface is a declarative as-code artifact — schema (`.pg`), queries (`.gq`), policies (`.yaml`), UI (`.yaml`), aliases, **ETL pipelines**, and embeddings config. The UI is not a separately-deployed application; it is a declarative spec, a first-class resource reconciled exactly like the others. + +Three pillars, none optional: + +1. **DECLARATIVE** — you describe the desired end state, not the steps. The reconciler computes the steps. +2. **AS CODE** — the config is declarative text in a repo, version-controlled. This is the **source of truth for *intent***. +3. **OPERATED BY AGENT** — an agent authors config changes and drives reconciliation as an authenticated actor, with policy and approval gates. No human state-management burden. + +This is **Terraform's model, taken literally**: config (as code) is desired truth; **state is an authoritative, locked ledger** of what has been applied — held in a backend (the cluster, or a separate cloud store); `plan` diffs config against state; `apply` converges reality to config and updates state — applied at **cluster** scope, with OmniGraph as its own data-aware provider and an agent as the controller. + +--- + +## Why as-code (the recursion argument) + +"As code" is not branding. It is the structural property that makes a self-describing system well-founded. + +Consider the rejected alternative: model the cluster's definition *as a graph* (a meta-graph whose nodes are graphs/policies/queries/UI). To describe a graph you need a schema. The meta-graph's schema is either: + +- **hardcoded** → the base case is *code* (you smuggled code in at the bottom anyway), or +- **another graph** → infinite regress, no base case. + +Graph-describing-graph never terminates. **Code is the base case.** A declarative config needs no meta-describer because it is parsed by the engine's compiled code — not described by more user-space data. + +> **Declarative-as-code terminates. Declarative-as-data (a graph of graphs) recurses.** + +This is also why **config** must live **outside** the running system: reviewable (PRs), reproducible (clone + apply), diffable as text, and editable by an agent — without depending on the running system to describe its own intent. + +Corollary on direction: change flows **code → cluster, never the reverse.** You do not edit the running system and call that intent. (State, separately, *records* what the cluster currently is — see the next section — but it is never where you express what it *should* be.) + +--- + +## Why per-cluster, not per-graph + +The definition Sarah changed does not *belong* to any single graph: + +1. **Policies cross-cut graphs.** "Member can't delete on any graph," "who may list/create/delete graphs" — cluster facts. No graph could own them. +2. **"Which graphs exist" has no home in a per-graph model.** The set of graphs is state *above* any graph. +3. **Queries, UI, pipelines, and aliases span graphs.** The MCP/tool catalog an agent discovers is the *cluster's* surface; a dashboard renders multiple graphs; a pipeline may fan out into several. +4. **Cross-graph apply groups.** Sarah may add a graph *and* wire it into the UI *and* grant policy access *and* attach a feed as one logical change — only the cluster can express, plan, and eventually fence that as one apply group. +5. **Operators operate clusters.** Bob is Sarah's peer on a *deployment*, not a graph. The collaboration unit is the cluster. + +The graph is a *resource within* the cluster, not the unit of operation. + +The mirror question — *why not per-fleet?* — is the same one this section used against per-graph, one level up. A fleet of clusters may eventually want its own declarative spec describing which clusters exist. That recursion is real but **out of scope here**: this proposal stops at the cluster because the cluster is the unit two operators collaborate over. Fleet is the next scope up, named and deferred, not denied. + +--- + +## The model: config / state / reconcile (the Terraform model, literally) + +| Layer | What it is | Source of truth for… | Who manages it | +|---|---|---|---| +| **Config** (as code, a folder of files) | Desired state of the whole cluster — graphs, schemas, policies, queries, UI, bindings, aliases, embeddings, ETL pipelines | **Intent** ("what it should be") | Operators/agents, in version control | +| **State** (a locked ledger in a backend) | The authoritative record of what has been applied — applied revision, per-resource fingerprints, observed graph/table versions, audit-record references, resource conditions | **Deployed reality** ("what is") | The reconciler; humans don't hand-edit it | +| **Actual cluster** | The realized *definition* of the running graphs — schema/policies/queries/UI/pipelines as actually in force | — (reality itself) | The engine; `apply` converges it to config | + +**`plan`** = `diff(config, state)` → proposed change set (optionally refreshed against the actual cluster). +**`apply`** = acquire the state lock → converge actual → config → **update state** → release lock. Apply does **not** acknowledge success until the state update succeeds; if actual moved but the state write failed, the next `plan` / `refresh` must surface the non-success state and repair or import it before more work proceeds. + +### State is an authoritative, locked ledger — not a throwaway projection + +This is the 2026-06-07 revision. State is treated exactly as Terraform treats `tfstate`: + +- **Authoritative.** State is the trusted record of what is deployed. `plan` diffs config against **state** (fast, deterministic), not against a full live scan of the cluster on every command. "What exists" is answered from state. +- **In a backend.** State lives in a configurable backend: the **cluster's own object-store backend**, or a **separate cloud store** (e.g. a different bucket/account) — the operator's choice, mirroring Terraform's local/S3/remote backends. The config declares which. +- **JSON first.** The baseline state format is Terraform-style JSON documents (`state.json` plus status/approval/recovery JSON records) protected by backend lock/CAS. Lance control-plane datasets are a possible later backend only if row-level history, queryability, or tighter publish fencing justifies the added machinery. +- **Atomicity depends on backend and publish scope.** A JSON state backend, even when stored under the cluster root, is a separate CAS step from graph Lance manifest moves. If actual resources move but the state write fails, apply must surface `ActualAppliedStatePending` (or equivalent) and require refresh/import repair instead of pretending one atomic commit covered every object. A future Lance-backed state backend or cluster manifest publisher may tighten this, but that is not the Phase-1 assumption. +- **Locked.** `plan`/`apply` acquire a **state lock** before touching state, so two operators (or two agents) cannot converge concurrently and corrupt the ledger. This generalizes the existing `__schema_apply_lock__` from schema scope to cluster scope. +- **Reconstructable, but not casually rebuilt.** OmniGraph's edge over opaque-cloud Terraform: the running cluster is self-describing (manifests, commit logs), so a lost state ledger can be **imported / refreshed** from the live cluster. That is a *resilience* property — not licence to treat state as disposable. State is protected and backed up like any source of truth. +- **One slice is never reconstructable.** Who *approved* an irreversible apply cannot be re-derived from a manifest scan. That approval/audit record lives in the **durable audit ledger** (baseline: append-only JSON records in the state backend; future: a Lance table only if needed). State *references* it by id; it never *is* it. + +**The control plane reconciles definition, not data.** The reconcile loop converges the cluster's *definition* — schema, policies, queries, UI, bindings, aliases, pipelines, and the set of graphs. It does **not** converge **data**: rows, edges, and vectors are data-plane content, mutated by `load`/`mutate` and by **pipeline execution**, versioned by the commit DAG, and they sit entirely outside the reconcile loop. (`load`/`mutate` never appear in `cluster.yaml`.) **Two** definition kinds *trigger* a data-plane effect without owning data — schema and ETL pipelines (see "ETL pipelines" below). + +### Cluster resource model + +Minimum vocabulary: + +- **ClusterRoot** — the object-store prefix / control namespace for one deployment. +- **DesiredRevision** — git commit, `cluster.yaml` digest, and per-resource digests. +- **ResourceKind** — `Graph`, `Schema`, `Query`, `PolicyBundle`, `UiSpec`, `Binding`, `Alias`, `EmbeddingConfig`, **`Pipeline`** (ETL), and future cluster-scoped resources. +- **ResourceAddress** — normalized typed references between resources, such as `graph.knowledge`, `query.knowledge.find_experts`, `policy.base_rbac`, and `pipeline.github_sync`; illustrative YAML may use shorthand, but plan/state store the typed form. +- **ProviderAddress** — typed references to provider instances, such as `provider.storage.prod_graphs`, `provider.source.github_org`, and `provider.embedding.default`; provider addresses keep storage, external sources, and embedding providers from being inferred from ambiguous strings. +- **StateBackend** — where the JSON state ledger is stored: `cluster` (this deployment's own backend) or an external store (a separate bucket/account). +- **StateLock** — the cluster-scope lock acquired before plan/apply. +- **AppliedRevision** — the durable, locked record (the heart of state) of which desired revision is applied, with audit-record references, resource fingerprints, and graph/table version observations. +- **ResourceStatus** — `Pending | Planned | Applying | Applied | Drifted | Blocked | Error`, with typed conditions and observed actual state. +- **ApplyGroup** — the explicit atomicity unit. Default is one independent resource per group; cross-resource references force planner-derived groups, and user-declared groups may opt into larger atomicity only for resources the active backend protocol can fence or repair. Baseline JSON state supports small, explicit groups; larger all-or-nothing groups require a future cluster publisher or equivalent proof. + +--- + +## State: backend, lock, and the config ↔ state diff + +The CLI is the operator's window onto the gap between config and state. + +The Terraform-aligned workflow is: + +```text +cluster validate # parse + schema-check desired config, no state mutation +cluster plan # diff desired config against state, with optional refresh +cluster apply # apply an accepted fresh plan and update state +cluster status # read what state says is deployed now +cluster refresh # update/import state observations from actual cluster state +``` + +`plan` is the central artifact. It records the desired revision, resource +digests for every referenced file, dependency edges between resources, observed +state fingerprints / graph manifest versions, proposed changes, and approval +gates. The human output below is a rendering of that structured plan, not the +only representation. + +``` + $ omnigraph cluster plan + config ./ → diff against state (backend: cluster · lock: acquired) + + ~ schema knowledge hard-drop Person.legacy_id ⚠ prior versions reclaimed — needs approval + + query knowledge.find_experts (new stored query) + - query knowledge.orphan_pages (removed) + ~ policy base_rbac grant invoke find_experts → members (this is what EXPOSES the new query) + + pipeline saas_sync notion → knowledge, hourly + ~ ui dashboards.overview add panel "experts" + + alias experts + ───────────────────────────────────────────────────────────────────── + 6 changes · 1 requires approval (hard schema drop on knowledge) · run `apply` to converge +``` + +<!-- Audit fix: enum narrowing is not implemented today; hard drops are the +current supported irreversible schema path, so the example must not teach a +future migration tier as if it already exists. --> +That output **is** the answer to the Sarah/Bob test: one diff, spanning every surface, attributed to a git commit and concrete resource digests, with data-impact peeked (axiom-6 schema seam), dependency fallout visible, observed state compared, and approval gates surfaced *before* anything moves. Drift (someone poked the live cluster out-of-band) shows up here too — `plan` reconciles state against the actual cluster and flags resources whose observed version no longer matches the ledger. + +<!-- Audit fix: JSON state is the baseline. It is inspectable and Terraform-like, +but it remains a separate CAS step from graph manifest movement. --> +`apply` then: acquire **state lock** → execute the change set (ordered/grouped per the planner) → **CAS-update the JSON state ledger** with the new applied revision/status observations → release the lock. For config-only resources, content-addressed payload writes can happen before the state CAS because state is the publish point. For graph/schema moves, the graph manifest may move before the state CAS; a crash or CAS failure there leaves a loud repair/import condition and no success acknowledgement, not a silently successful atomic apply. A future cluster manifest publisher can tighten this gap, but the baseline protocol does not assume it. + +--- + +## ETL pipelines (the second data-plane seam) + +External data — from another database, an API, a file drop, a stream — is a first-class config asset, not glue code that lives nowhere. + +A **Pipeline** is declared in config: a **source** (e.g. `notion`, `github`, `slack`, `gdrive`, `postgres`, `http`, `s3-files`, `kafka`), an optional **schedule/trigger**, and **one or more target graphs**, each with its own **mapping/transform** (external records → graph types & properties). A single feed can **fan out across graphs** — e.g. a GitHub sync that populates both the `engineering` graph and the people/teams in `knowledge`. It is reconciled like any resource — `apply` creates / updates / deletes / (re)schedules the pipeline *definition*. This is the canonical "company brain" move: the deployment's graphs are continuously assembled from the SaaS tools the org already uses. + +The crucial boundary (axiom 6, axiom 13): the pipeline **definition** is control-plane and reconciled; the pipeline's **execution** — actually pulling rows and writing them — is a **data-plane effect** that produces ordinary `load`/`mutate` commits *outside* the reconcile loop. The reconciler converges the pipeline; the rows it ingests are never reconciled state (just as a cron *definition* is config but its output is not). This makes ETL the **second seam** where a definition triggers a data-plane effect — schema being the first (a migration conforms existing rows; ETL ingests new ones). + +Consequences that fall out of the existing model: + +- **`plan` previews the pipeline, not the data.** "pipeline `saas_sync`: notion → `knowledge`, hourly" is a definition diff; it does not scan the source (data-volume-independent), the same way schema `plan` previews impact only at the bounded, opt-in data peek. +- **Source credentials come from the `.env` file** (axiom 10): `token: ${NOTION_TOKEN}` — resolved from the gitignored `.env` file per deployment, never inline. +- **Reversibility gradient applies** (axiom 8): a pipeline that *appends* is reversible-ish; one configured to *overwrite* a target is a data-loss path and hits the irreversible-op gate. +- **Referential integrity is plan-time** (axiom 9): a pipeline whose `into:` names a graph/type the same revision removes is a fail-closed `plan` error. +- **Fan-out is statusful, not magically atomic.** A pipeline execution that writes to several graphs is a set of ordinary per-target graph writes unless the pipeline explicitly stages through a branch/merge protocol that can fence those targets. A failed run may therefore leave `engineering=Applied`, `knowledge=Error` (for example), and the pipeline run ledger must expose per-target status, commit ids, retryability, and idempotency keys. Control-plane `apply` only converges the definition/schedule; it never means every future data-plane target has ingested successfully. + +--- + +## Config assets — the full set + +Everything below is **shared cluster config** (in the folder, version-controlled, secret-free) unless marked per-operator. The rule of thumb: if two operators must agree on it, it's config; if it's how *you personally* reach or view the cluster, it's per-operator. + +| Asset | In config? | Notes | +|---|---|---| +| **Graphs** (the set that exists) | ✅ config | the named graphs; their existence is cluster state | +| **Schema** (`.pg`, **one per graph**) | ✅ config | also encodes indexes (`@index`/`@unique`/vector), constraints, and search (`@embed`) — so indexes & search are reconciled *via* schema | +| **Stored queries** (`.gq`, **per graph**) | ✅ config | a `.gq` file declares **many** named queries; the registry declares which exist (name → file, key must match the `query <name>` symbol). **Target design:** exposure — who may list/invoke each — is a policy decision, not a registry flag. **Current compatibility bridge:** shipped `omnigraph.yaml` still has `queries.<name>.mcp.expose`, and the HTTP catalog is not Cedar-filtered per query yet.

A *purely personal* shortcut (your own command abbreviations) stays in the per-operator layer. When in doubt: if it should survive `git clone` and be the same for Bob as for Sarah, it's config. + +--- + +## The synthesis (beyond vanilla Terraform) + +Embracing Terraform does not mean stopping at Terraform. Three extensions make this specifically right for OmniGraph and the agentic future: + +1. **OmniGraph is its own data-aware provider, and `plan` can peek across the data boundary.** A Terraform provider CRUDs resources blind to your data. Here, the control-plane resource is the schema **definition** (declarative, reconciled); converging it *triggers* a data-plane **effect** — currently soft/hard drops, rewrites, and index creation, with future validated migrations such as enum narrowing or `String`→`enum` conversion once the planner grows that tier. The leverage is that `plan`, before applying the definition change, can *peek* at bounded data-plane consequence and report it — **"hard-dropping this property requires approval and will make prior versions unreachable after cleanup"** or, in the future, **"narrowing this enum will fail on 37 rows"** — which Terraform structurally cannot do. This is deliberate and bounded: a data peek makes that `plan` cost scale with data volume, so it is **opt-in / bounded** (sampled or skippable for large tables), and it never makes the control plane the owner of data. Schema and ETL pipelines are the **two** seams where the control plane reaches into the data plane; everywhere else `plan` is data-volume-independent. + +2. **JSON state first, explicit partials, optional stronger fencing later.** Terraform apply is not transactional — partial applies are a real failure mode. Lance commits are per dataset, and today's OmniGraph manifest atomicity is graph-scoped: one graph commit flips the relevant sub-table versions together, protected by expected table versions and recovery sidecars. The first cluster-control backend should match Terraform's shape: a locked JSON state document plus append-only JSON status/approval/recovery records. That keeps Phase 1 inspectable and narrow. Cluster-level all-or-nothing apply is a later capability only if we add a **cluster manifest publisher** or Lance-backed state backend that fences graph *version pins*, query catalogs, policy bundles, UI specs, pipeline definitions, recovery sidecars, and state as one commit protocol. Until that exists, apply must surface partial convergence as `ResourceStatus`, not pretend it was atomic. + +3. **Agent-as-controller fuses Terraform with Kubernetes.** Terraform contributes the as-code config (truth outside the system, recursion-terminating) and the locked state ledger. Kubernetes contributes *continuous* reconciliation (controllers watch, not apply-on-demand). The agent is both author and controller: it reads a config change, runs the data-aware plan, evaluates blast radius against the reversibility gradient, **auto-applies the reversible parts only when policy permits, and escalates irreversible / data-loss gates to a human approval artifact recorded in the audit ledger and referenced by state.** + +> Terraform's as-code config + locked state × Kubernetes' continuous reconciliation × the agent as the controller that bridges them — on OmniGraph's data-aware, atomic substrate. + +--- + +## Concrete shape (illustrative) + +The config is **a set of files in one folder** (flat, Terraform-style — the extension carries the type): + +``` + company-brain/ + ├── cluster.yaml # the spec (graphs, policies, ui, bindings, aliases, pipelines, state, vars ref) + ├── .env # SECRET VALUES — gitignored, never committed + ├── knowledge.pg · engineering.pg # schemas (one per graph) (.pg) + ├── knowledge.gq · engineering.gq # query files — each holds MANY queries (.gq) + ├── cluster_admin.policy.yaml · base_rbac.policy.yaml · knowledge_pii.policy.yaml # shared policy bundles + ├── overview.dashboard.yaml # cross-graph UI spec (.dashboard.yaml) + └── notion_to_knowledge.map.yaml · github_to_engineering.map.yaml · github_to_people.map.yaml # pipeline maps +``` + +Secrets live in a gitignored `.env` file (OmniGraph's standard env-file convention); the config references them as `${NAME}`: + +```bash +# .env — secret values; gitignored; never committed.

It is parsed by the engine (the base case), describes the desired cluster, and is the thing two operators diff and review. + +The **state ledger** lives in the configured backend (the cluster, or a separate cloud store), versioned, CAS-updated, schema-versioned, locked during apply, agent-managed — the authoritative record of what is deployed. The baseline backend is JSON, so even cluster-hosted state is published through a state CAS and repaired explicitly if graph/resource movement happened first. A future cluster publisher can tighten that boundary, but it is not assumed by the high-level spec. + +--- + +## Boundaries that hold (orthogonal correctness, not Terraform-bias) + +1. **Secrets live in a `.env` file, never inline in config.** The committed config is what the cluster *is* (shared, reviewable, as code) and carries **no secret values** — only `${NAME}` references. The values (embedding API key, pipeline source credentials, per-deployment settings) live in a separate **`.env` file** — which is **gitignored and never committed**, and supplied per deployment. Separately, an *operator's own token* (how they personally reach the cluster) belongs to the per-operator connection layer, not the cluster config or its `.env` file. + +2. **The reversibility gradient gates apply — including drift correction.** Dropping a graph, hard-dropping schema data, or an overwriting pipeline is irreversible data loss; a future validated enum narrowing is a compatibility-narrowing migration unless it also drops or coerces stored values; recoloring a dashboard is not. Unified config, unified plan — but **tiered gates inside apply**, keyed to physics, not to who operates it. The gate applies to **drift correction too**: converging actual→config can mean *dropping* something added out-of-band — a data-loss path that hits the same gate. A reconciler "just fixing drift" is never an exception. + +3. **Agents are actors, not ambient authority.** The reconciler runs with a resolved actor or service account, subject to Cedar policy. If it applies on behalf of a human, the durable audit ledger carries both the controller actor and the approving human / approval artifact, and state references that ledger entry. Client-supplied actor identity is never trusted. + +4. **Status is explicit when apply is not atomic.** A unified plan does not imply a unified commit. If an apply group partially converges, the cluster must expose `ResourceStatus` and typed conditions until reconciliation finishes or rolls back. Silent partial success is forbidden. + +5. **State integrity is protected.** State is locked during apply and stored durably in its backend. The baseline state backend is JSON plus lock/CAS, so state update failures surface a repair/import condition before success is acknowledged. A lost ledger is recoverable (import/refresh from the self-describing cluster), but state is never treated as disposable. + +--- + +## Relationship to current config + +This is not green field, but it is also not today's `omnigraph.yaml`. The current file is a shared convenience for CLI and server startup: named graph targets, server defaults, query roots, aliases, embeddings model, auth env-file lookup, and `policy.file`. It is **not** the cluster's source of truth, it has no separate state ledger, and parts of it are intentionally per-operator. + +This proposal: + +- **splits** per-operator connection/credential/preference config from shared cluster config, +- **adds** `cluster.yaml` + a flat config folder as the full declarative cluster config (graphs, schemas, query catalog, policy bundles, UI specs, bindings, **aliases**, **embeddings**, **ETL pipelines**), +- **adds** the **JSON state ledger** (authoritative, locked, in a backend) and the `cluster plan`/`apply` loop, +- **adds** the reconciler (with OmniGraph as its own data-aware provider), while treating a cluster manifest publisher as a later option rather than the baseline, +- **lets an agent drive** plan/apply/continuous-reconcile. + +The connection/credential/preference layer remains per operator: it points at a cluster, resolves that operator's identity, and holds personal ergonomics. The cluster config stays shared, secret-free, and reviewable; the state ledger stays authoritative and locked. + +Implementation gate: the Terraform-style workflow must be testable in order. +`cluster validate` must catch bad config before any apply path exists; +read-only `cluster plan` must have deterministic structured-plan tests before +state mutation ships; and graph/schema-moving apply must have recovery tests for +the gap between graph/resource movement and JSON state publish. Otherwise the +control plane can look declarative while still hiding drift or partial success. + +--- + +## Open questions + +1. **Cluster state layout.** What exact JSON documents / object-store paths hold `AppliedRevision`, `ResourceStatus`, approval records, recovery records, sidecars, and resource content for query/policy/UI/pipeline specs? What evidence would justify a future Lance-backed state backend? +2. **State backend options.** Beyond "cluster" and "a separate bucket," what backends are first-class (a different account, a remote control service)? How is the backend itself bootstrapped and its lock implemented (object-store CAS vs an external lock service)? +3. **State import / refresh.** The exact actual-state scan that reconstructs a conservative `AppliedRevision` when the ledger is lost, and which fields become `Unknown`. +4. **Apply grain syntax.** Apply defaults to per-resource `ApplyGroup`; cross-resource references force planner-derived groups; user-declared groups opt into more atomicity. What's the YAML, and which combinations can the publisher actually fence? +5. **Pipeline runtime.** Where do pipelines *execute* (in the server? a worker? an external scheduler?), how are runs observed in `ResourceStatus`, and how does a failed/partial run reconcile vs. retry? +6. **Continuous reconciliation trigger.** Watch-and-converge (k8s-style) vs. apply-on-config-change. The agent-as-controller model leans toward continuous. +7. **Tenant partitioning (cloud).** A cluster may host multiple tenants; config/state is then tenant-partitioned, consistent with the reserved `GraphKey { tenant_id, graph_id }`. Tenant resolved from the token, never the config. +8. **Bootstrap — config, state, *and* authority.** How a cluster comes into existence from an initial config (`init` seeds; cluster owns; git mirrors for CI/DR), the first state write, and the chicken-and-egg of the very first apply (which needs an actor before any cluster exists to resolve policy against — so the bootstrap actor is necessarily out-of-band and privileged). Security-sensitive; needs an explicit story. +9. **Alias scoping.** Where exactly the shared/personal alias line falls, and whether shared aliases are just stored-query catalog entries. +10. **UI render and safety model.** Generic engine-side renderer vs. thin client, allowed components, query-binding validation, policy propagation, sandboxing, version compatibility. +11. **Cluster identity vs. `metadata.name`.** Is `metadata.name` a label or stable identity? If identity, renaming loses it — the stable-ID-across-rename gap already in `invariants.md`. Decide whether identity keys on `name` or on `ClusterRoot`, and reuse the existing known-gap framing. +12. **Resource dependency ordering.** Explicit dependency DAG (Terraform) vs. eventual convergence with retries (k8s). The most consequential unmade fork: it decides whether `plan` can promise an apply *order* before any data moves. +13. **Query exposure in policy (supersedes `mcp.expose`).** *Today* the stored-query registry carries a per-query `mcp.expose` flag and invocation is gated with the coarse `invoke_query` Cedar action — with **per-query authorization a documented gap** (the catalog isn't Cedar-filtered per query yet). This design **folds exposure fully into policy and drops the flag**: a stored query's visibility (catalog membership) and invocability are both policy decisions, so the catalog `GET /queries` returns each actor's policy-permitted set. The open work is the exact policy predicates for *list* vs *invoke* per query, and retiring `mcp.expose`. + +--- + +## Prior art + +- **Terraform** — declarative infra *as code*; config is desired truth, **state is an authoritative ledger in a backend**, **state locking** serializes applies, `plan` diffs config↔state, providers do the CRUD. The core model adopted here, taken literally. +- **Kubernetes** — one cluster store, many resource types under one API; controllers reconcile continuously; cluster-level RBAC. The continuous-reconciliation half of the synthesis. +- **dbt / Airflow / Dagster** — declarative, as-code data pipelines with lineage. Prior art for the **ETL-pipeline-as-config** asset (the second data-plane seam). +- **OmniGraph's own schema-apply** — already a faithful plan/apply/state/drift loop for the `schema` resource type, with `__schema_apply_lock__` as the lock seed; the reconciler this generalizes. diff --git a/docs/dev/index.md b/docs/dev/index.md index 1e41342..49b6d76 100644 --- a/docs/dev/index.md +++ b/docs/dev/index.md @@ -73,6 +73,7 @@ Working documents for in-flight feature work.

It was a non-required (non-blocking) check, so it never gated a merge — it only burned the slowest/most expensive runner (windows-latest, --release, 75-min ceiling) on every code change. Windows binary validation is already covered (better) on release tags: release.yml's `smoke_windows_installer` (on v* tags) builds the release binaries, installs via scripts/install.ps1, and smoke-runs `omnigraph.exe version` + `omnigraph-server.exe --help` — the same smoke test plus the real installer path. Nothing `needs:` the removed job. Trade-off (accepted): a PR that breaks the Windows build or install.ps1 syntax is now caught at release-cut rather than at PR time. install.ps1 and platform-specific code change rarely; the cost savings on every PR outweigh the earlier signal.

Add bypass_pull_request_allowances for the two engineering owners (ragnorc, aaltshuler): they merge their own PRs after CI without a second review; non-owners still require a code-owner approval. CI status checks remain required for everyone. Applied live via scripts/apply-branch-protection.sh.

All three layers ship; the five migrated writers (`MutationStaging::finalize`, `schema_apply`, `branch_merge`, `ensure_indices`, `optimize_all_tables`) write a `__recovery/{ulid}.json` sidecar before Phase B and delete it after Phase C. The next `Omnigraph::open` (gated on `OpenMode::ReadWrite`) runs the sweep in `db/manifest/recovery.rs`: classify, decide all-or-nothing per sidecar, roll forward via single `ManifestBatchPublisher::publish` or roll back via `Dataset::restore` followed by a manifest publish of the restored version (so both directions converge to `manifest == HEAD` — no residual drift), and record an audit row in `_graph_commit_recoveries.lance` (queryable via `omnigraph commit list --filter actor=omnigraph:recovery`).

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.

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. --- Cargo.lock | 53 + crates/omnigraph/Cargo.toml | 1 + crates/omnigraph/examples/bench_expand.rs | 61 + crates/omnigraph/src/exec/projection.rs | 29 + crates/omnigraph/src/exec/query.rs | 1146 ++++++++++++++--- crates/omnigraph/src/table_store.rs | 124 ++ crates/omnigraph/tests/fixtures/search.gq | 14 + crates/omnigraph/tests/helpers/mod.rs | 9 + .../omnigraph/tests/lance_surface_guards.rs | 135 ++ crates/omnigraph/tests/literal_filters.rs | 96 ++ crates/omnigraph/tests/merge_truth_table.rs | 8 +- crates/omnigraph/tests/ordering.rs | 134 ++ .../omnigraph/tests/proptest_equivalence.rs | 311 +++++ crates/omnigraph/tests/search.rs | 105 ++ crates/omnigraph/tests/traversal.rs | 188 +++ crates/omnigraph/tests/traversal_indexed.rs | 327 +++++ docs/user/constants.md | 17 + docs/user/indexes.md | 4 +- docs/user/query-language.md | 4 +- 19 files changed, 2570 insertions(+), 196 deletions(-) create mode 100644 crates/omnigraph/tests/literal_filters.rs create mode 100644 crates/omnigraph/tests/ordering.rs create mode 100644 crates/omnigraph/tests/proptest_equivalence.rs create mode 100644 crates/omnigraph/tests/traversal_indexed.rs diff --git a/Cargo.lock b/Cargo.lock index 3064196..578188c 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -4627,6 +4627,7 @@ dependencies = [ "object_store 0.12.5", "omnigraph-compiler", "omnigraph-policy", + "proptest", "regex", "reqwest", "serde", @@ -5141,6 +5142,25 @@ dependencies = [ "unicode-ident", ] +[[package]] +name = "proptest" +version = "1.11.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "4b45fcc2344c680f5025fe57779faef368840d0bd1f42f216291f0dc4ace4744" +dependencies = [ + "bit-set", + "bit-vec", + "bitflags", + "num-traits", + "rand 0.9.2", + "rand_chacha 0.9.0", + "rand_xorshift", + "regex-syntax", + "rusty-fork", + "tempfile", + "unarray", +] + [[package]] name = "prost" version = "0.14.3" @@ -5202,6 +5222,12 @@ dependencies = [ "cc", ] +[[package]] +name = "quick-error" +version = "1.2.3" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "a1d01941d82fa2ab50be1e79e6714289dd7cde78eba4c074bc5a4374f650dfe0" + [[package]] name = "quick-xml" version = "0.37.5" @@ -5373,6 +5399,15 @@ dependencies = [ "rand 0.9.2", ] +[[package]] +name = "rand_xorshift" +version = "0.4.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "513962919efc330f829edb2535844d1b912b0fbe2ca165d613e4e8788bb05a5a" +dependencies = [ + "rand_core 0.9.5", +] + [[package]] name = "rand_xoshiro" version = "0.7.0" @@ -5772,6 +5807,18 @@ version = "1.0.22" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "b39cdef0fa800fc44525c84ccb54a029961a8215f9619753635a9c0d2538d46d" +[[package]] +name = "rusty-fork" +version = "0.3.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "cc6bf79ff24e648f6da1f8d1f011e9cac26491b619e6b9280f2b47f1774e6ee2" +dependencies = [ + "fnv", + "quick-error", + "tempfile", + "wait-timeout", +] + [[package]] name = "ryu" version = "1.0.23" @@ -6759,6 +6806,12 @@ dependencies = [ "web-time", ] +[[package]] +name = "unarray" +version = "0.1.4" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "eaea85b334db583fe3274d12b4cd1880032beab409c0d774be044d4480ab9a94" + [[package]] name = "unicase" version = "2.9.0" diff --git a/crates/omnigraph/Cargo.toml b/crates/omnigraph/Cargo.toml index 24b0c9c..9cc2148 100644 --- a/crates/omnigraph/Cargo.toml +++ b/crates/omnigraph/Cargo.toml @@ -55,3 +55,4 @@ omnigraph-compiler = { path = "../omnigraph-compiler", version = "0.6.2" } tokio = { workspace = true } lance-namespace-impls = { workspace = true } serial_test = "3" +proptest = "1" diff --git a/crates/omnigraph/examples/bench_expand.rs b/crates/omnigraph/examples/bench_expand.rs index c723b24..bb904a0 100644 --- a/crates/omnigraph/examples/bench_expand.rs +++ b/crates/omnigraph/examples/bench_expand.rs @@ -221,6 +221,65 @@ fn microbench_dedup() { ); } +/// Selective single-source traversal, timed cold in CSR vs indexed mode across +/// growing |E|.

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. --- crates/omnigraph/src/exec/merge.rs | 38 +++-- crates/omnigraph/src/loader/mod.rs | 199 +++++++++++++++++++------- crates/omnigraph/src/table_store.rs | 2 +- crates/omnigraph/tests/consistency.rs | 67 ++++++++- docs/dev/invariants.md | 2 +- 5 files changed, 235 insertions(+), 73 deletions(-) diff --git a/crates/omnigraph/src/exec/merge.rs b/crates/omnigraph/src/exec/merge.rs index 0e6434b..1068f90 100644 --- a/crates/omnigraph/src/exec/merge.rs +++ b/crates/omnigraph/src/exec/merge.rs @@ -670,36 +670,34 @@ fn update_unique_constraints( table_key: &str, batch: &RecordBatch, constraints: &[Vec<String>], - seen: &mut [HashMap<String, String>], + seen: &mut [HashMap<Vec<String>, String>], conflicts: &mut Vec<MergeConflict>, ) -> Result<()> { for (constraint_idx, columns) in constraints.iter().enumerate() { let seen = &mut seen[constraint_idx]; - for row in 0..batch.num_rows() { - let mut parts = Vec::with_capacity(columns.len()); - let mut any_null = false; - for column_name in columns { - let column = batch.column_by_name(column_name).ok_or_else(|| { + // Resolve the group's columns once.
