# ruflo-ruvector

Self-learning vector database powered by [`ruvector@0.2.25`](https://www.npmjs.com/package/ruvector) — HNSW, Adaptive LoRA embeddings, hooks-based intelligence, SONA self-optimizing patterns, brain (collective knowledge), and 91 MCP tools (verified via `ruvector mcp tools`).

> **Pinned version:** this plugin targets `ruvector@0.2.25`. Earlier 0.1.x versions are missing several commands (`brain`, `route`, `sona`); some legacy docs referenced 2.x features that do not exist on npm. Always invoke with the pin.

## Overview

Wraps the `ruvector` npm package as a Ruflo plugin, providing vector embedding, semantic search, code-graph clustering, hyperbolic projection, self-learning hooks, and SONA / Brain diagnostics. ruvector's Rust backend delivers sub-millisecond queries and 52,000+ inserts/sec.

## Prerequisites

```bash
# Required
npm install ruvector@0.2.25

# Optional add-ons (install as needed)
npm install ruvector-onnx-embeddings-wasm   # required for `embed text` to work
npm install @ruvector/pi-brain              # required for `brain` subcommands
npm install @ruvector/ruvllm                # required for `sona` subcommands (JS fallback)
```

Run a health check:
```bash
npx -y ruvector@0.2.25 doctor
```

## Installation

```bash
claude --plugin-dir plugins/ruflo-ruvector
```

## MCP Integration (91 Tools)

Register with the pinned version:
```bash
claude mcp add ruvector -- npx -y ruvector@0.2.25 mcp start
```

Key tool categories: hooks routing, AST analysis, diff classification, coverage routing, graph clustering, security scanning, RAG context, brain knowledge, SONA learning.

```

## End-to-End Example: store + search project files

```bash
# 0. One-time setup
/vector-setup

# 1. Create a database
npx -y ruvector@0.2.25 create project.db -d 384 -m cosine

# 2. Embed every TypeScript source file (loop — no built-in --batch)
mkdir -p .vec
for f in $(find src -name '*.ts'); do
  npx -y ruvector@0.2.25 embed text "$(cat "$f")" -o ".vec/${f//\//_}.json"
done

# 3. Insert all embeddings (assumes a JSON array of {id, vector, metadata})
jq -s '[.[] | {id: input_filename, vector: .vector}]' .vec/*.json > corpus.json
npx -y ruvector@0.2.25 insert project.db corpus.json

# 4. Search by query embedding
QV=$(npx -y ruvector@0.2.25 embed text "JWT refresh-token rotation" --output -)
npx -y ruvector@0.2.25 search project.db -v "$QV" -k 5

# 5. Inspect index health
npx -y ruvector@0.2.25 stats project.db
```

For an alternative store format with lineage tracking, replace steps 1–3 with:
```bash
npx -y ruvector@0.2.25 rvf create project.rvf
npx -y ruvector@0.2.25 rvf ingest project.rvf < corpus.json
npx -y ruvector@0.2.25 rvf query project.rvf
```

### Known limitations / bugs in 0.2.25

| Issue | Detail | Workaround |
|-------|--------|-----------|
| ONNX runtime missing | `embed text` → `ONNX WASM files not bundled` | `npm i ruvector-onnx-embeddings-wasm` (see `/vector-setup`) |
| `optimize` | Self-reports "not yet shipped in this release" | none — track upstream issue 401 |
| `hooks force-learn` | TypeError `intel.tick is not a function` | run a real trajectory via `trajectory-begin/step/end` |
| `hooks graph-mincut` | `Cannot read properties of undefined (reading 'length')` | use `hooks graph-cluster` |
| `hooks git-churn` | Fails outside a git repo | run from inside the repo |
| `benchmark` | Some installs fail with `Missing field 'dimensions'` | use `attention benchmark` or `gnn search` benchmarking |
| `cluster` (top-level) | `Status: Coming Soon` | use `hooks graph-cluster` |
| `compare`, top-level `index`, `midstream`, `embed --file/--batch/--glob/--model poincare` | Don't exist | see `commands/vector.md` for replacements |

## Self-Learning Hooks

```bash
# Full pretrain pipeline + agent generation
npx -y ruvector@0.2.25 hooks init --pretrain --build-agents quality

# Smart agent routing (positional task!)
npx -y ruvector@0.2.25 hooks route "implement OAuth flow"
npx -y ruvector@0.2.25 hooks route-enhanced "fix CVE-2025-1234"

# Code analysis (positional file!)
npx -y ruvector@0.2.25 hooks ast-analyze src/module.ts
npx -y ruvector@0.2.25 hooks diff-analyze HEAD
npx -y ruvector@0.2.25 hooks coverage-route src/module.ts
npx -y ruvector@0.2.25 hooks security-scan src/
```

## Brain (Collective Knowledge)

```bash
npm install @ruvector/pi-brain   # required dependency

npx -y ruvector@0.2.25 brain status
npx -y ruvector@0.2.25 brain search "authentication patterns"
npx -y ruvector@0.2.25 brain list
npx -y ruvector@0.2.25 brain drift code   # knowledge drift for a domain
```

## SONA (Self-Optimizing Neural Architecture)

```bash
npx -y ruvector@0.2.25 sona status
npx -y ruvector@0.2.25 sona patterns "auth refactor"
npx -y ruvector@0.2.25 sona stats
```

## Performance

| Operation | Latency | Notes |
|-----------|---------|-------|
| HNSW search | ~0.045ms | 8,800x vs ONNX inference |
| Memory cache | ~0.01ms | 40,000x vs ONNX inference |
| Insert | 52,000+/sec | Rust backend (`@ruvector/core`) |
| Memory per vector | ~50 bytes | Efficient storage |

## Known Caveats

- **ONNX runtime not bundled by default** — `embed text` will report `ONNX WASM files not bundled` until you install `ruvector-onnx-embeddings-wasm`.
- **No `--file`, `--batch`, `--glob`, `--namespace`, `--k`, `--task`, `--model poincare` flags** — these were in older docs but never shipped in 0.2.25. See `agents/vector-engineer.md` for the replacement table.
- **`brain` requires `@ruvector/pi-brain`** — install separately.
- **`sona` requires `@ruvector/ruvllm`** — install separately (the native binding is not always present in the npm tarball).
- **Top-level `cluster` is "Coming Soon"** — for actual clustering use `hooks graph-cluster <files>`.
- **`compare`, `midstream`, top-level `index` subcommands do not exist.**

## Architecture Decisions

- [`ADR-0001` — Pin ruflo-ruvector to ruvector@0.2.25 with optional add-ons](./docs/adrs/0001-pin-ruvector-0.2.25.md)

## Smoke test

```bash
bash plugins/ruflo-ruvector/scripts/smoke.sh
# Expected: "11 passed, 0 failed"
```
