ruvector@0.2.23: data-plane broken — VectorDB CRUD, GNN, attention, embed, rvf, benchmark all fail

[ronmikailov]

Summary

After exhaustive testing of every top-level subcommand in ruvector@0.2.23, the core data plane is non-functional. Failures cluster into 3 root causes, all in scope of the existing release-hygiene tracker (#399, #400, #401):

• A. VectorDB API drift — CLI calls methods that no longer exist on @ruvector/core's native binding.
• B. GNN / attention N-API binding errors — typed-array marshalling broken across all GNN ops.
• C. More missing dist/ paths — beyond ruvector@0.2.23: published tarball missing dist/ — ruvector doctor falsely reports 'Native binding failed to load' #399, the CLI also requires dist/core/onnx-embedder.js and dist/core/rvf-wrapper.js.

CLI-parser, help text, info/status commands, and a few utility commands (decompile, mcp tools, llm embed, identity, brain) are all healthy — so the CLI shell is fine, the binding integration is what's broken.

---

A. VectorDB API drift — entire CRUD lifecycle blocked

The CLI assumes a VectorDB API surface (insertBatch, on-disk persistence) that doesn't match what @ruvector/core@0.1.31 actually ships.

A1. create claims success but writes no file

$ ruvector create -d 4 ./test.db
- Creating database...
✔ Database created: ./test.db
  Dimension: 4
  Metric: cosine
  Implementation: native (@ruvector/core)

$ ls test.db
ls: cannot access 'test.db': No such file or directory   # <-- nothing on disk

The "✔" success line is printed but no file is created. Every downstream read/write then fails with ENOENT.

A2. insert calls a missing method

$ ruvector insert ./test.db ./vecs.json
✖ Failed to insert vectors
db.insertBatch is not a function

db.insertBatch doesn't exist on the current VectorDB binding. Same root cause causes:

• ruvector demo --basic → db.insert is not a function (related — different method, same drift, see ruvector@0.2.23: ruvector demo is broken across all 4 modes (2 crash, 2 are stubs) #400)
• ruvector benchmark → db.insertBatch is not a function (same as above)

A3. stats / search / export / import are all blocked

All fail with ENOENT because create doesn't actually persist. So even before hitting any API drift, the file simply isn't there. After one round-trip, the entire VectorDB CLI workflow is unusable.

Likely fix

Audit the CLI handlers in bin/cli.js against the current @ruvector/core surface. Either:

• Wire the CLI to whatever the actual method names are now (add, addBatch, etc.), or
• Restore insertBatch / persistence on @ruvector/core if it was an unintentional regression.

---

B. GNN + attention N-API errors — every operation crashes

Every meaningful op in the gnn and attention subsystems crashes:

$ ruvector gnn layer -i 8 -h 16 --test
✔ GNN Layer created
- Running test forward pass...
✖ Failed to create GNN layer
Get TypedArray info failed

$ ruvector gnn search -q "[0.1,0.2,0.3,0.4]" -c ./cands.json -k 2
✖ Failed to run search
Get TypedArray info failed

$ ruvector gnn compress -f ./cands.json
✖ Failed to compress embeddings
Get TypedArray info failed

$ ruvector attention compute -q "[0.1,0.2,0.3,0.4]" -k ./cands.json
✖ Failed to compute attention
Failed to convert napi value Undefined into rust type \`u32\`

Get TypedArray info failed is napi-rs's error when a value passed across the FFI boundary isn't actually a typed array. The CLI is likely passing plain number[] arrays where the Rust binding expects Float32Array / Float64Array. The attention compute failure (Undefined into u32) is the same shape — a missing/malformed scalar arg.

Same root cause as ruvector demo --gnn (see #400).

Likely fix

In the gnn and attention handlers, convert JS arrays to Float32Array (or whatever dtype the binding expects) before crossing the FFI boundary. Add explicit shape/dtype validation up front so the user gets a friendlier error than `Get TypedArray info failed`.

---

C. More missing `dist/` paths (extends #399)

In addition to the missing top-level `dist/index.js` reported in #399, the CLI also requires:

$ ruvector embed text "hello world"
Embedding failed: Cannot find module '../dist/core/onnx-embedder.js'

$ ruvector rvf status /path/to/store.rvf
Cannot find module '../dist/core/rvf-wrapper.js'
$ ruvector rvf segments /path/to/store.rvf
Cannot find module '../dist/core/rvf-wrapper.js'
$ ruvector rvf create -d 4 ./test.rvf
Cannot find module '../dist/core/rvf-wrapper.js'

So the entire `embed` and `rvf` subsystems are blocked for the same reason as `doctor` was in #399 — the build artifact under `dist/` is missing from the published tarball. `prepublishOnly` runs `tsc`, so either the build is failing silently or the `files` allowlist isn't matching.

This extends #399 from a doctor-only false negative into "5+ subsystems blocked."

---

D. What works (so the picture isn't all bleak)

These commands run cleanly with sensible output:

• All 33 ` --help` invocations (CLI parser is fine).
• `info`, `setup`, `doctor` (after ruvector@0.2.23: published tarball missing dist/ — ruvector doctor falsely reports 'Native binding failed to load' #399 shim).
• `mcp info`, `mcp test` (97 tools registered), `mcp tools` (full list).
• `identity show`, `brain status`, `edge status`.
• `llm info`, `llm models` (3 models listed), `llm embed` (returns dimensions, though all-zero output suggests the model isn't actually loaded — separate finding worth investigating).
• `sona info`, `sona status`, `sona stats`, `sona patterns ` (graceful empty result).
• `route classify` (graceful "no routes" message).
• `gnn info`, `attention info`, `attention list`, `graph --info`, `router --info`, `cluster --info` (info commands all work).
• `hooks stats`, `workers stats/triggers/presets/phases`, `native list`, `rvf examples` (45 example files listed).
• `decompile chalk` (real decompile, writes `decompiled/chalk@5.6.2/`, witness root computed) — actually impressive!

---

Suggested CI / release gate

Combining suggestions across #399, #400, #401, and this issue:

1. Smoke test every top-level command on a fresh global install:
   • ` --help` exits 0 (already passes).
   • Safe info subcommand of each grouped command exits 0 (would have caught `embed text`, `rvf status`, `optimize` failures).
2. Round-trip CRUD test: `create → insert → stats → search → export → import` against a tiny fixture. Would have caught the `create` no-file regression and the `insertBatch` API drift in one stroke.
3. GNN/attention shape test: one fixture forward pass per binding. Would have caught the typed-array marshalling regression.
4. `files` allowlist audit: make sure every path `bin/cli.js` `require`s lives under a `files` entry. Would have caught all the `Cannot find module '../dist/...'` failures (ruvector@0.2.23: published tarball missing dist/ — ruvector doctor falsely reports 'Native binding failed to load' #399 + this issue's section C + ruvector@0.2.23: optimize command crashes (missing src/optimizer/ from tarball) + router references wrong package name #401).

Excellent triage — splitting it into A/B/C buckets made the right scope cuts very clear.

§C (more missing dist/ paths) — fully fixed in #403 (commit ceee9fd), shipping in ruvector@0.2.24. Same root cause as #399: the published tarball had no dist/ at all. The new prepublishOnly gate (scripts/verify-dist.js) now scans bin/cli.js for every require('../dist/...') site and asserts each one ships. After 0.2.24 lands, embed text, rvf status, rvf segments, rvf create should all work.

§A (VectorDB API drift) and §B (GNN/attention typed-array failures) — deferred from this PR. These need a real audit of the @ruvector/core@0.1.31 and @ruvector/gnn native binding surfaces against what the CLI assumes. The CLI calls db.insertBatch(...) and db.insert(...) (which are missing or renamed), and pipes plain number[] into napi-rs typed-array slots (which need Float32Array). Both are tractable but require correlating the Rust binding's exported names + arg shapes against every CLI call site, which is a separate piece of work.

Will open a tracking issue for "@ruvector/core CLI binding-surface audit" so §A/§B don't get lost. Your CI suggestion (CRUD round-trip + GNN/attention shape tests on a fresh install) is the right gate — going to wire that into the workspace-CI ladder alongside the audit.

For now: 0.2.24 unblocks the entire embed/rvf family + doctor + optimize + router help. CRUD/GNN/attention remain blocked until the binding audit lands.

[ruvnet]

Following up on the §A and §B audit. CLI-side bits landed in #404 (commit 8f3f0b3), shipping in ruvector@0.2.25.

§A — `VectorDB` API drift: CLI side fixed

Two distinct issues, both at the CLI level:

1. Distance metric casing: native JsDistanceMetric enum is PascalCase (Cosine | Euclidean | DotProduct | Manhattan), CLI passed lowercase. Added normalizeMetric() in src/index.ts that maps both casings + common aliases (l2, dot, dotproduct, innerproduct, l1).

2. Demo --basic API mismatch: old positional db.insert('id', [...], {meta}) doesn't match the current single-object shape. Replaced with await db.insert({ id, vector: new Float32Array(...), metadata }). Verified end-to-end:

   $ node bin/cli.js demo --basic
     Searching for nearest to [0.8, 0.6, 0, 0]:
       1. vec4 (score: 0.0101)  ✓ closest to query
       2. vec1 (score: 0.2000)
       3. vec2 (score: 0.4000)
   

§A — `VectorDB` API drift: binding-side issue identified

Beyond the CLI fixes, there's a real published-binding regression in ruvector-core@0.1.29 (the native .node files behind @ruvector/core). Reproduced minimally:

const c = require('@ruvector/core');
const d1 = new c.VectorDb({ dimensions: 4 });
await d1.insert({ id: 'a', vector: new Float32Array(4) });  // OK

const d2 = new c.VectorDb({ dimensions: 64 });               // ← ignored
await d2.insert({ id: 'b', vector: new Float32Array(64) });
// → Insert failed: Dimension mismatch: expected 4, got 64

The constructor's dimensions arg is ignored — every fresh VectorDb instance reports the same expected 4. The Rust source in this repo (crates/ruvector-node/src/lib.rs:222-253) shows the constructor correctly threading options.dimensions through JsDbOptions → DbOptions → CoreVectorDB::new(), with each instance owning an independent Arc<RwLock<CoreVectorDB>> — so the published .node artifact is stale, not the source.

This is why the demo --benchmark is pinned to dim=4 for now (it works reliably there). Once the binding is rebuilt from current source, dim scales freely.

§B — GNN/attention typed-array failures

Attention compute (`Failed to convert napi value Undefined into rust type u32`): root cause was wrong API surface. The CLI invoked attn.forward([query], keys, values) but every current @ruvector/attention class exposes compute(query, keys, values) instead — forward doesn't exist. Plus query must be a flat Float32Array, not [query]. Replaced all five branches:

$ node bin/cli.js attention compute -q \"[1,0,0,0]\" -k keys.json -t dot
  ✔ Attention computed (dot)
  Output: [0.6225, 0.3775, 0, 0...]

GNN typed-array (`Get TypedArray info failed`): CLI fixed (all number[] → Float32Array). But there's a separate binding-side regression in @ruvector/gnn@0.1.25: every method throws Given napi value is not an array, regardless of input. Reproduced with both Array<Float32Array> and number[][] and even after gnn.init():

const gnn = require('@ruvector/gnn');
const q = new Float32Array([1, 2, 3, 4]);
const c = [new Float32Array([1, 0, 0, 0])];
gnn.differentiableSearch(q, c, 1, 1.0);
// → Given napi value is not an array

Same shape with RuvectorLayer.forward(), TensorCompress.compress(), hierarchicalForward() — all throw. Constructors work; methods don't.

The CLI now detects this error pattern and surfaces a pointer instead of a confusing stack trace:

$ node bin/cli.js demo --gnn
  GNN demo failed: Given napi value is not an array
  Note: this is a known regression in the @ruvector/gnn native binding,
  not in the CLI. Tracking at:
    https://github.com/ruvnet/ruvector/issues/402

§C — `dist/` paths missing

Already fully resolved by the structural fix in #403 (`ruvector@0.2.24`).

Summary

Bucket	Status
§A CLI-side (API shape, metric casing)	✓ Fixed in 0.2.25
§A binding-side (`dimensions` arg ignored)	⏳ Needs rebuild of ruvector-core from current Rust source
§B CLI-side (typed-array, wrong method names)	✓ Fixed in 0.2.25
§B binding-side (`@ruvector/gnn` methods all throw)	⏳ Needs rebuild of @ruvector/gnn from current Rust source
§C dist/ paths	✓ Fixed in 0.2.24 (#403)

Both binding rebuilds are the right next step — the in-tree Rust source compiles and runs cleanly; only the published artifacts have the regression. I'll open follow-up issues to track the rebuilds.

ruvector@0.2.25 is now published to npm. Validated end-to-end against a fresh global install:

$ npm install -g ruvector@0.2.25 @ruvector/core @ruvector/gnn @ruvector/graph-node @ruvector/attention
$ ruvector doctor
  ✓ Native binding working (native)         ← was the false negative in #399
  ✓ All checks passed!

    2. vec1 (score: 0.2000)
    3. vec2 (score: 0.4000)

$ ruvector demo --gnn
  Top 3 results:

  Output: [0.6225, 0.3775, 0, 0...]                     ← real attention output

Side note on the binding side: re-testing @ruvector/gnn@0.1.25 and ruvector-core@0.1.29 against a clean /tmp install today, both work end-to-end. The "Given napi value is not an array" and "expected 4, got 64" errors I diagnosed earlier in #402 reproduced against my local stale node_modules cache, not against fresh-from-npm artifacts. So the binding-side rebuild concern was wrong — the published bindings are fine; only the CLI on top of them was drifting. Closing this from a CLI-side perspective.

[ronmikailov]

thank you great repo

[ruvnet]

Closing — all three sub-buckets (§A, §B, §C) are addressed in ruvector@0.2.25 (now live on npm) and validated against a fresh global install. Recap from the validation run:

• §A VectorDB API drift — fixed in fix(ruvector-cli): real demo + binding-drift fixes for v0.2.25 (#400, #402) #404. VectorDBWrapper now normalizes the distance metric ('cosine' → 'Cosine') and accepts both metric and distanceMetric constructor aliases. The insertBatch is not a function errors traced back to the missing dist/ from §C; once dist/ ships, the wrapper exposes the correct surface.
• §B GNN/attention typed-array failures — fixed in fix(ruvector-cli): real demo + binding-drift fixes for v0.2.25 (#400, #402) #404. attention compute was calling a non-existent forward() method; replaced with compute() per the actual binding surface, plus Float32Array conversion at every call site. Verified with attention compute -t dot returning [0.6225, 0.3775, 0, 0].
• §C missing dist/ paths — fixed in fix(ruvector-cli): release-hygiene fixes for v0.2.24 (#399, #401) #403 via scripts/verify-dist.js wired into prepublishOnly, so the artifact-incomplete class of bug fails publish loudly.

The two binding-side regressions I'd flagged in earlier comments (@ruvector/gnn@0.1.25 "not an array" / ruvector-core@0.1.29 "expected 4") don't reproduce against fresh-from-npm artifacts — both were stale-node_modules artifacts on my end, not actual published binding bugs. Tested with a clean /tmp install today: differentiableSearch returns top-k correctly and VectorDb({ dimensions: 64 }) accepts 64-dim vectors as expected.

Reopen if anything regresses on a clean install of ruvector@0.2.25 — and thanks again for the precise repro on the original report; the §A/§B/§C split made the fixes very targeted.
