+            # Binary Micro-Witness Bundle
+
+            Generated: {DateTimeOffset.UtcNow:O}
+
+            ## Contents
+
+            - `witness.json` - The binary micro-witness predicate
+            - `verify.ps1` - PowerShell verification script (Windows)
+            - `verify.sh` - Bash verification script (Linux/macOS)
+
+            ## Quick Verification
+
+            ### Windows (PowerShell)
+            ```powershell
+            .\verify.ps1
+            ```
+
+            ### Linux/macOS (Bash)
+            ```bash
+            chmod +x verify.sh
+            ./verify.sh
+            ```
+
+            ## Witness Details
+
+            - **CVE**: {predicate?.Cve.Id ?? "N/A"}
+            - **Binary Digest**: {predicate?.Binary.Digest ?? "N/A"}
+            - **Verdict**: {predicate?.Verdict ?? "N/A"}
+            - **Confidence**: {predicate?.Confidence ?? 0:P0}
+            - **Computed At**: {predicate?.ComputedAt.ToString("O") ?? "N/A"}
+
+            ## Offline Verification
+
+            This bundle is designed for air-gapped verification. No network access is required
+            to verify the witness contents. Signature and Rekor proof verification require
+            the bundled public keys and tile proofs (when available).
