+# Mirror
+
+**Status:** Implemented
+**Source:** `src/Mirror/`
+**Owner:** Platform Team
+
+## Purpose
+
+Mirror creates offline package mirrors and advisory snapshots for air-gapped deployments. Enables deterministic, offline-first operation by capturing point-in-time snapshots of external package repositories and vulnerability feeds.
+
+## Components
+
+**Services:**
+- `StellaOps.Mirror.Creator` - Mirror creation and management tool
+
+**Scripts:**
+- `make-thin-v1.sh` - Thin mirror creation script
+- `schedule-export-center-run.sh` - Integration with ExportCenter for scheduled exports
+
+## Configuration
+
+Configuration is typically provided via CLI arguments or environment variables.
+
+Key features:
+- Package repository mirroring (distro mirrors, language ecosystems)
+- Advisory feed snapshots (CSAF, OSV, NVD)
+- Thin mirror creation (metadata-only for bandwidth optimization)
+- Integration with ExportCenter for bundle creation
+- Air-gap bundle generation
+
+## Dependencies
+
+- ExportCenter (for bundle packaging)
+- AirGap (for import/validation)
+- External package repositories and advisory feeds (as mirror sources)
+
+## Related Documentation
+
+- AirGap Module: `../airgap/`
+- ExportCenter: `../export-center/`
+- Offline Kit: `../../24_OFFLINE_KIT.md`
+- Operations: `./operations/` (if exists)
+
+## Current Status
+
+Mirror.Creator implemented with thin mirror support. Integrated with ExportCenter for air-gap bundle generation. Used for offline deployment preparation.
