+        ### 🔐 STRICT Non-Negotiables Compliance
+        
+        **This implementation enforces ALL non-negotiables:**
+        
+        1. **NO Hardcoding**: Every threshold, ratio, and parameter comes from configuration
+        2. **NO Estimations**: Only actual measured compression ratios and memory usage
+        3. **NO Fallbacks**: Fails fast on errors (e.g., attention sparsity calculation)
+        4. **NO Fake Results**: Fixed seeds, reproducible bootstrapping
+        5. **Clean Code**: Full validation, explicit error handling, no silent failures
+        
+        ### 📦 Proving Protocol Features
+        
+        **Attestable Proof Bundle (.zip) contains:**
+        - `manifest.json`: Full environment, config hash, timestamps
+        - `summary.json`: Aggregated metrics (recomputable)
+        - `records/metrics.jsonl`: Per-sample raw measurements
+        - `records/kv_fingerprints.jsonl`: Layer-level compression data
+        - `env.lock`: Exact package versions
+        
+        **Verification:**
+        - Recomputes summary from raw records
+        - Checks numeric tolerances (configurable)
+        - Validates compression ratio floor
+        - All tolerances configurable, not hardcoded
+        
+        **CI Integration:**
+        - Run `verify_proof_bundle()` in CI
+        - Hard-fail if verification fails
+        - Ensures reproducibility
+        
+        This ensures research-grade reproducibility and integrity.
