CLI Offline Proof-of-Existence Verification

Module

Cli

IMPLEMENTED

CLI has offline proof-of-existence verification capability documented and implemented through evidence commands.

PoE Commands: src/Cli/StellaOps.Cli/Commands/PoE/ExportCommand.cs -- proof-of-existence export
PoE Verify: src/Cli/StellaOps.Cli/Commands/PoE/VerifyCommand.cs -- proof-of-existence verification
Offline Command Group: src/Cli/StellaOps.Cli/Commands/OfflineCommandGroup.cs -- offline operations including PoE
Command Handlers: src/Cli/StellaOps.Cli/Commands/CommandHandlers.Offline.cs -- offline mode handlers
Offline Mode Guard: src/Cli/StellaOps.Cli/Services/OfflineModeGuard.cs -- enforces offline-only operations
Exit Codes: src/Cli/StellaOps.Cli/Commands/OfflineExitCodes.cs -- offline-specific exit codes
Documentation: src/Cli/OFFLINE_POE_VERIFICATION.md
Commands:
- stella poe export <digest> -- export proof-of-existence bundle
- stella poe verify <bundle> -- verify PoE bundle offline
- stella offline verify -- offline verification mode

Run stella poe export sha256:abc123 --output ./poe-bundle/ and verify bundle created with Rekor proofs
Run stella poe verify ./poe-bundle/ and verify offline PoE verification passes
Verify PoE verification works without network connectivity (air-gapped)
Verify tampered bundle fails verification with clear error message
Run stella offline verify <digest> and verify offline verification mode works
Verify exit codes follow OfflineExitCodes convention
