Status: Accepted Date: 2026-03-01 Authors: RuVector Team Deciders: ruv Related: ADR-070 (npx ruvector Unified Integration), ADR-064 (Pi Brain Infrastructure), ADR-066 (SSE MCP Transport), ADR-058 (Hash Security Optimization)
A comprehensive deep review of the ruvector npm package (v0.2.2) — the unified CLI, MCP server, and SDK for the π.ruv.io collective intelligence platform — was performed. The review tested all 48 CLI commands across 12 command groups and 91 MCP tools using a live PI key against the production π.ruv.io endpoint.
The audit revealed security vulnerabilities, error handling gaps, and UX friction points that needed immediate remediation before the v0.2.3 release.

Fix all HIGH and MEDIUM severity issues found during the audit, publish v0.2.3 with security patches, and document the findings for future reference.
Issue: The edge balance command placed the raw PI key directly in the URL path:
// BEFORE (vulnerable)
const resp = await fetch(`${EDGE_GENESIS}/balance/${piKey}`, ...);This is a critical security violation — URL paths are logged by proxies, CDNs, web servers, and browser history. A 64-character hex PI key in the path leaks the user's identity and authentication credential.
Fix: Derive a SHAKE-256 pseudonym from the PI key and use that in the URL. The raw key is sent only in the Authorization header (which is not logged by standard infrastructure):
// AFTER (secure)
const pseudonym = require('crypto')
.createHash('shake256', { outputLength: 16 })
.update(piKey)
.digest('hex');
const resp = await fetch(`${EDGE_GENESIS}/balance/${pseudonym}`, {
headers: { 'Authorization': `Bearer ${piKey}` }
});Files modified: bin/cli.js, bin/mcp-server.js
Rationale: SHAKE-256 is the same hash function used throughout the RVF wire format (ADR-058). The 16-byte (32-hex-char) pseudonym is sufficient for routing without revealing the key. The Authorization header is the standard HTTP mechanism for bearer tokens and is stripped by well-configured reverse proxies before logging.
Issue: npx ruvector sona status crashes with Module not found when @ruvector/sona native bindings aren't installed. The SONA package has optional native acceleration via N-API that requires platform-specific compilation.
Status: Not fixed in this release — the crash is in the @ruvector/sona package itself, not in the ruvector CLI. The CLI already lazy-loads SONA and catches import errors for the top-level module, but internal native binding failures propagate.
Mitigation: Future @ruvector/sona release should wrap native binding calls in try-catch with WASM fallback.
Issue: Edge network commands (edge genesis, edge balance) crashed when the backend returned non-JSON error responses (404, 502, etc.):
SyntaxError: Unexpected token 'N', "Not Found" is not valid JSON
The code called resp.json() without checking resp.ok first.
Fix: Added response status check before JSON parsing in both CLI and MCP server:
if (!resp.ok) {
const errText = await resp.text().catch(() => resp.statusText);
console.error(chalk.red(`Edge network returned ${resp.status} ${resp.statusText}`));
process.exit(1);
}Files modified: bin/cli.js, bin/mcp-server.js
Issue: npx ruvector hooks remember -v "some value" failed with error: required option '-t, --type <type>' not specified. For a convenience command, requiring the type flag on every invocation is excessive UX friction.
Fix: Changed from requiredOption to option with a default value of 'general':
// BEFORE
.requiredOption('-t, --type <type>', 'Memory type')
// AFTER
.option('-t, --type <type>', 'Memory type', 'general')Files modified: bin/cli.js
Issue: Brain commands fail when @ruvector/pi-brain is not installed. It's declared as an optional peerDependency in package.json, but the error message isn't user-friendly.
Status: Working as designed — pi-brain is an optional peer dependency. The lazy-load pattern already provides a clear error: "Install @ruvector/pi-brain for brain commands". Users who want brain features install it separately.
Issue: bin/cli.js is 8,582 lines — a large single file. While it works correctly and loads fast (54.6ms), it makes maintenance harder.
Status: Deferred. The file loads fast due to lazy-loading of heavy dependencies (GNN, attention, ora). Splitting would add complexity without performance benefit. If the file exceeds 10,000 lines, consider splitting by command group.
Issue: hooks recall --query uses exact string matching (includes()) rather than semantic/fuzzy search. This limits discovery of related memories.
Status: Deferred. Semantic search would require loading SONA embeddings for every recall, adding ~200ms latency. The current approach is fast and predictable.

Fast startup is achieved through lazy-loading: heavy modules (GNN, attention, SONA, ora) are only require()'d when their commands are invoked.

A single 64-hex PI key derives all identity components:
PI Key (64 hex chars)
├── SHAKE-256(key, 16 bytes) → Pseudonym (32 hex chars)
│ └── Used in: URL paths, public identifiers
├── HMAC-SHA256(key, "mcp-auth") → MCP Token
│ └── Used in: MCP server authentication
└── SHA-512(key) → first 32 bytes → Ed25519 Seed
└── Used in: Edge network identity, signing
- Never expose keys in URLs — use derived pseudonyms (SHAKE-256)
- Constant-time comparison —
subtle::ConstantTimeEqfor wire hash verification - Lazy credential loading — PI key read from env/file only when needed
- AES-256-GCM for key export with password-derived encryption
- No credential logging — CLAUDE.md explicitly forbids echoing/printing credentials
A comprehensive validation of all 27 REST endpoints on the live π.ruv.io backend was performed.

| 0.2.2 | 2026-02-28 | Core version display fix, chalk ESM compat |
| 0.2.3 | 2026-03-01 | Security: PI key URL fix, edge 404 handling, hooks UX |
- PI key no longer leaked in URL paths across all edge commands
- Edge commands gracefully handle backend errors instead of crashing
hooks rememberis more ergonomic with sensible defaults- Comprehensive benchmark baseline established for future optimization
- All 55 unit tests continue to pass
- SONA native binding crash remains (fix requires @ruvector/sona release)
- CLI monolith continues to grow (8,582 lines)
- hooks recall still uses exact match (semantic search deferred)
- SHAKE-256 pseudonym collision: negligible at 128 bits (2^64 birthday bound)
- Edge 404 text fallback:
resp.text()could theoretically be large; mitigated by Cloud Run response limits
