validate-logic

name	validate-logic
description	Validates all trade decisions and produces ERC-8004 style proof hashes

When to Use

• When asked to verify agent output or trade decisions
• When generating validation reports for paper trading sessions
• When auditing the proof log for consistency

Instructions

1. Collect all inputs for a trade decision:
   • Raw market data (prices, volumes, indicators)
   • Strategy module outputs (momentum, mean-reversion, yield signals)
   • AI predictor output (final prediction, confidence, weights)
   • Risk manager results (approved/rejected, reasons, adjusted size)
2. Generate SHA256 hash of the full decision record:

   import hashlib
   import json
   
   def generate_proof_hash(decision_record: dict) -> str:
       canonical = json.dumps(decision_record, sort_keys=True, separators=(',', ':'))
       return hashlib.sha256(canonical.encode('utf-8')).hexdigest()
   

3. Store the hash in validation/proof_log.jsonl with:
   • proof_hash: The SHA256 hash
   • timestamp: ISO 8601 UTC timestamp
   • decision_summary: Human-readable trade summary
   • full_record: Complete decision record for verification
4. Output a validation report for each trade:
   • Pass/Fail status for each risk check
   • Proof hash
   • Any warnings or anomalies detected

Validation Checks

For each trade decision, verify:

• All required fields are present in the decision record
• Timestamp is valid ISO 8601 format
• Strategy signals are in valid format with confidence in [0.0, 1.0]
• Risk manager was consulted (not bypassed)
• If trade was executed, risk manager approved it
• Proof hash matches the decision record (re-hash to verify)
• Proof hash is unique (no duplicate hashes in the log)

Verification Function

def verify_proof(record: dict, expected_hash: str) -> bool:
    """Re-hash the record and compare with expected hash."""
    actual_hash = generate_proof_hash(record)
    return actual_hash == expected_hash
