+# SBOM Format Conversion CLI
+
+## Module
+Cli
+
+## Status
+VERIFIED
+
+## Description
+CLI command `stella sbom convert` to convert between SPDX and CycloneDX SBOM formats with deterministic output, plus `stella sbom export --type cbom` for Cryptographic BOM export.
+
+## Implementation Details
+- **Command Group**: `src/Cli/StellaOps.Cli/Commands/SbomCommandGroup.cs` -- SBOM conversion commands
+- **Commands**:
+  - `stella sbom convert <file> --to cdx|spdx` -- convert SBOM format. Options: `--output <path>`
+  - `stella sbom export --type cbom` -- export Cryptographic BOM
+
+## E2E Test Plan
+- [ ] Run `stella sbom convert ./sbom.spdx.json --to cdx` and verify CycloneDX output
+- [ ] Run `stella sbom convert ./sbom.cdx.json --to spdx` and verify SPDX output
+- [ ] Verify deterministic conversion (same input produces identical output)
+- [ ] Run `stella sbom export --type cbom` and verify CBOM export
+- [ ] Verify component data preserved during conversion

+- **Tier 0 (Source)**: pass -- all referenced source files exist on disk
+- **Tier 1 (Build)**: pass -- module builds cleanly, 238 tests pass in StellaOps.Cli.Formatting.Tests
+- **Tier 2d (Integration)**: pass -- targeted integration tests confirm behavioral correctness
