# Offline Verdict Verification CLI Plugin

## Module
Cli

## Status
IMPLEMENTED

## Description
Offline and online verdict verification via CLI plugin: verify verdict signatures, replay bundles for deterministic verification, and validate input hashes using knowledge snapshots without server connectivity.

## Implementation Details
- **Command Group**: `src/Cli/StellaOps.Cli/Commands/VerdictCommandGroup.cs` -- `VerdictCommandGroup` for verdict commands
- **Command Handlers**: `src/Cli/StellaOps.Cli/Commands/CommandHandlers.VerdictVerify.cs` -- verdict verification handlers
- **Verdict Verifier**: `src/Cli/StellaOps.Cli/Services/VerdictAttestationVerifier.cs` -- verdict attestation verification
- **Offline Kit**: `src/Cli/StellaOps.Cli/Services/OfflineKitStateStore.cs` -- offline kit state management
- **Offline Mode Guard**: `src/Cli/StellaOps.Cli/Services/OfflineModeGuard.cs` -- offline mode enforcement
- **Commands**:
  - `stella verdict verify <digest>` -- verify verdict signature and integrity
  - `stella verdict replay <digest>` -- replay verdict for deterministic verification
  - `stella verdict verify-offline <bundle>` -- offline verification using knowledge snapshot

## E2E Test Plan
- [ ] Run `stella verdict verify sha256:abc123` and verify signature validation
- [ ] Run `stella verdict replay sha256:abc123` and verify deterministic replay
- [ ] Run `stella verdict verify-offline ./bundle/` and verify offline verification
- [ ] Verify offline mode works without network connectivity
- [ ] Verify input hash validation against knowledge snapshot
- [ ] Verify exit code 0 for valid, non-zero for invalid
