 ## Engineering Rules
 - Target `net10.0`; prefer latest C# preview allowed in repo.
-- Offline-first: no new external network calls; use cached feeds (`/local-nugets`).
+- Offline-first: no new external network calls; use `.nuget/packages/` cache.
 - Determinism: stable ordering, UTC ISO-8601 timestamps, no `DateTime.Now`/random without seed; normalize path separators.
 - Logging: structured (`ILogger` message templates); avoid secrets/paths leakage.
 - Security: no executing untrusted payloads; keep analyzers pure; include redaction guidance for runtime capture adapters.

+- **CBOM Support**: Generate CycloneDX 1.7 Cryptographic BOM with `cryptographicProperties` for crypto asset inventory.
+
+## CBOM (Cryptographic BOM) Support
+
+The Emit module supports CycloneDX 1.7 CBOM generation for cryptographic asset inventory:
+
+### Key Components
+
+| Component | Path | Purpose |
+|-----------|------|---------|
+| `ICryptoAssetExtractor` | `Cbom/ICryptoAssetExtractor.cs` | Interface for language-specific crypto extraction |
+| `CryptoProperties` | `Cbom/CryptoProperties.cs` | CycloneDX 1.7 crypto schema types |
+| `CbomAggregationService` | `Cbom/CbomAggregationService.cs` | Aggregates crypto assets with risk assessment |
+| `CycloneDxCbomWriter` | `Composition/CycloneDxCbomWriter.cs` | Injects cryptographicProperties into CycloneDX JSON |
+
+### Crypto Extractors
+
+Language-specific extractors implement `ICryptoAssetExtractor`:
+- `DotNetCryptoExtractor`: System.Security.Cryptography patterns
+- `JavaCryptoExtractor`: BouncyCastle, JWT libraries, JCA patterns
+- `NodeCryptoExtractor`: npm crypto packages (bcrypt, crypto-js, sodium, etc.)
+
+### Usage Pattern
+
+```csharp
+// 1. Aggregate crypto assets from components
+var cbomService = new CbomAggregationService(extractors, logger);
+var cbomResult = await cbomService.AggregateAsync(components, context);
+
+// 2. Inject into CycloneDX output
+var enhancedJson = CycloneDxCbomWriter.InjectCbom(
+    cycloneDxJson,
+    cbomResult.ByComponent);
+```
+
+### Risk Assessment
+
+The aggregation service automatically assesses crypto risk:
+- **Deprecated**: MD5, SHA-1, DES, RC2, RC4
+- **Weak**: Small key sizes, ECB mode, unauthenticated encryption
+- **Quantum Vulnerable**: RSA, DSA, ECDSA, ECDH, DH
+- **Post-Quantum Ready**: ML-KEM, ML-DSA, SLH-DSA, SPHINCS+
 
 ## Interfaces & Dependencies
 - Consumes analyzer outputs (OS, language, native) and EntryTrace usage annotations.
