name trader-backtest description Run a historical backtest using npx neural-trader with Rust/NAPI engine (8-19x faster) and walk-forward validation; Ed25519-sign the result for paper→live tamper evidence (ADR-126 Phase 4) allowed-tools Bash Read mcp__plugin_ruflo-core_ruflo__memory_store mcp__plugin_ruflo-core_ruflo__memory_retrieve mcp__plugin_ruflo-core_ruflo__memory_search mcp__plugin_ruflo-core_ruflo__memory_delete mcp__plugin_ruflo-core_ruflo__neural_train mcp__plugin_ruflo-core_ruflo__agentdb_pattern-store argument-hint <strategy-name> --symbol <TICKER> [--period 2020-2024] Run a historical backtest using the neural-trader Rust/NAPI engine, then Ed25519-sign the result so the paper→live promotion gate has cryptographic tamper evidence (ADR-126 Phase 4 + CWE-347 pattern). Steps: Ensure neural-trader is available: npm ls neural-trader 2>/dev/null || npm install --ignore-scripts neural-trader Check for saved strategy config: mcp__plugin_ruflo-core_ruflo__memory_retrieve({ key: "strategy-STRATEGY_NAME", namespace: "trading-strategies" }) If not found, list available: mcp__plugin_ruflo-core_ruflo__memory_search({ query: "strategy", namespace: "trading-strategies", limit: 10 }) Run backtest via neural-trader CLI: npx neural-trader --backtest --strategy <name> --symbol <TICKER> --period <range> --walk-forward For multi-indicator strategies: npx neural-trader --backtest --strategy multi-indicator --position-sizing kelly --symbol SPY --period 2020-2024 Capture performance metrics from output: total return, annualized return, Sharpe ratio, Sortino ratio, max drawdown, win rate, profit factor, number of trades. Dedup prior backtests for the same (strategyId, paramsHash) before storing the fresh one (ADR-125 lifecycle / ADR-126 Phase 2 — keep-newest semantics): Search: mcp__plugin_ruflo-core_ruflo__memory_search({ query: "backtest STRATEGY paramsHash:PARAMS_HASH", namespace: "trading-backtests", limit: 10 }) For each hit whose key matches backtest-STRATEGY-* AND whose stored paramsHash equals the current run's hash, delete it: mcp__plugin_ruflo-core_ruflo__memory_delete({ key: "OLD_KEY", namespace: "trading-backtests" }) (Note: even without this proactive step, the MemoryConsolidator.dedup('keep-newest') background pass introduced in @claude-flow/memory@3.0.0-alpha.18 runs every 6h and will eventually converge. Doing it inline keeps memory_search results deterministic immediately after a re-run.) Sign the artifact (ADR-126 Phase 4): Build the SignedBacktestArtifact body — { strategyId, paramsHash, dataRange: {from,to}, metrics, runsHash, generatedAt } — where paramsHash = sha256(canonical params JSON) , runsHash = sha256(canonical runs array JSON) , and generatedAt = new Date().toISOString() . Resolve the witness signing key. The skill reads the key path in this order; the FIRST that resolves wins: RUFLO_WITNESS_KEY_PATH env var — points to a JSON file with { "privateKey": "<hex>" } . verification/witness-key.json (the ADR-103 default path, if present). If the key resolves: call signBacktestArtifact(body, privateKeyHex) from plugins/ruflo-neural-trader/src/signed-artifact.mjs . The returned value is a SignedBacktestArtifact with schema , witnessPublicKey: "ed25519:<hex>" , and witnessSignature: "<hex>" populated. If NEITHER path resolves: log a loud warning — "[WARN] ruflo-neural-trader: no witness signing key found (RUFLO_WITNESS_KEY_PATH unset, verification/witness-key.json missing) — storing backtest artifact in UNSIGNED degraded mode. paper→live promotion will be refused by trader-cloud-backtest until a signed artifact replaces this one." — and store the body unsigned. NEVER silently fall back. Store the (possibly signed) artifact to the canonical trading-backtests namespace: mcp__plugin_ruflo-core_ruflo__memory_store({ key: "backtest-STRATEGY-TIMESTAMP", value: JSON.stringify(signedArtifact), namespace: "trading-backtests" }) The stored value contains witnessSignature + witnessPublicKey when signed; downstream consumers ( trader-cloud-backtest ) MUST call verifyBacktestArtifact(artifact, trustedPublicKey) before promoting any artifact to live. If Sharpe > 1.5, store as successful pattern: mcp__plugin_ruflo-core_ruflo__agentdb_pattern-store({ pattern: "profitable-STRATEGY_TYPE", data: "PARAMS_AND_RESULTS" }) Train SONA on the outcome: mcp__plugin_ruflo-core_ruflo__neural_train({ patternType: "trading-strategy", epochs: 10 }) Key sourcing & key rotation (ADR-103) The witness key is a 32-byte Ed25519 private key, stored as { "privateKey": "<64-hex-chars>" } in a JSON file referenced by RUFLO_WITNESS_KEY_PATH . Keep it OUT of the repo. For local development, generate one once with node -e "import('@noble/ed25519').then(async ed=>{const sk=crypto.getRandomValues(new Uint8Array(32));console.log(Buffer.from(sk).toString('hex'))})" and write it to ~/.ruflo/witness-key.json . Production deployments pin the corresponding PUBLIC key in project config and supply it as trustedPublicKey to verifyBacktestArtifact(...) — never trust the witnessPublicKey field on the artifact itself (CWE-347 / #1922). Key rotation: re-sign existing backtest entries with the new key OR explicitly mark pre-rotation artifacts as non-promotable. Same pattern as ADR-103.
