+# Facet
+
+> Cryptographically sealed manifests for logical slices of container images.
+
+## Purpose
+
+The Facet Sealing subsystem provides cryptographically sealed manifests for logical slices of container images, enabling fine-grained drift detection, per-facet quota enforcement, and deterministic change tracking.

+| **Maintainer** | Scanner Guild, Policy Guild |
+
+## Key Features
+
+- **Facet Types**: OS packages, language dependencies, binaries, configs, custom patterns
+- **Cryptographic Sealing**: Each facet can be individually sealed with a cryptographic snapshot
+- **Drift Detection**: Monitor changes between seals for compliance enforcement
+- **Merkle Tree Structure**: Content-addressed storage with integrity verification
+
+## Dependencies
+
+### Upstream (this module depends on)
+- **Scanner** - Facet extraction during image analysis
+- **Attestor** - DSSE signing for sealed facets
+
+### Downstream (modules that depend on this)
+- **Policy** - Drift detection and quota enforcement
+- **Replay** - Facet verification in replay workflows
