        ### 🔐 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.
