+# Function Map CLI
+
+## Module
+Cli
+
+## Status
+VERIFIED
+
+## Description
+Runtime linkage verification workflow: generate function_map predicates from SBOMs defining expected runtime call paths and hot functions, then verify actual runtime observations against the map with DSSE signing and Rekor attestation.
+
+## Implementation Details
+- **Command Group**: `src/Cli/StellaOps.Cli/Commands/FunctionMap/FunctionMapCommandGroup.cs` -- `FunctionMapCommandGroup`
+- **Commands**:
+  - `stella function-map generate <sbom>` -- generate function_map predicate from SBOM
+  - `stella function-map verify <map> --observations <file>` -- verify runtime observations against function map
+  - `stella function-map sign <map>` -- DSSE-sign the function map
+  - `stella function-map attest <map>` -- submit function map to Rekor
+- **Proof Commands**: `src/Cli/StellaOps.Cli/Commands/Proof/FuncProofCommandGroup.cs` -- function proof generation
+- **Proof Handlers**: `src/Cli/StellaOps.Cli/Commands/Proof/FuncProofCommandHandlers.cs` -- function proof handlers
+
+## E2E Test Plan
+- [ ] Run `stella function-map generate ./sbom.json` and verify function_map predicate generated
+- [ ] Run `stella function-map verify ./map.json --observations ./runtime.json` and verify verification results
+- [ ] Verify mismatch detection when runtime observations differ from expected map
+- [ ] Run `stella function-map sign ./map.json` and verify DSSE signing
+- [ ] Run `stella function-map attest ./map.json` and verify Rekor submission
+- [ ] Verify `--format json` output
