+# Solidity & AI Agent Security Remediation Benchmark v4 — Commercial Preview
+
+Curated by **[Oxford Digital](https://oxforddigitals.com)** (`Offlin33er`)
+
+> **Instant Commercial Access (1,600 Full Records in Parquet + CSV + JSONL):** This Hugging Face repository hosts a free **100-row stratified preview** so ML engineers, security teams, and autonomous AI buyer agents can inspect exact schemas and remediation quality directly in the Dataset Viewer.
+>
+> - **Buy & Download Full 1,600-Row Archive Instantly (24/7 API, MCP & Stripe Checkout):** [Get Full Access on DataBazaar](https://databazaar.io/browse)
+> - **Custom Enterprise Licensing & Feeds:** [oxforddigitals.com/datasets](https://oxforddigitals.com/datasets) | `support@oxforddigitals.com`
+
+## What Is Inside the Full v4 Archive (1,600 Verified Records)
+
+1. **Solidity v0.8.20–0.8.26 Smart Contract Audit & Remediation Pairs (800 Records):**
+   - Tokenized vault share accounting, async settlement state ordering, two-step governance controls, oracle staleness validation, EIP-712 domain/nonce replay protection, proxy initializer lockouts, bounded pull-claim distributions, and fee-on-transfer balance-delta accounting.
+2. **AI Agent, MCP, RAG & LLM Guardrail Remediation Pairs (800 Records):**
+   - Python & TypeScript implementations covering MCP tool workspace confinement, RAG untrusted-context isolation, autonomous agent loop/budget circuit breakers, strict Pydantic structured output parsing, human-in-the-loop cryptographic approval gates, read-only parameterized Text-to-SQL tooling, multi-tenant vector ACL filtering, and deterministic RLVR reward graders.
+3. **Zero Public Overlap:**
+   - 100% private, deduplicated records cryptographically verified against public `Offlin33er/solidity-audit-instruct` (v1–v3) splits to prevent benchmark contamination.
