+# Auth Revocation Bundle Export/Verify CLI (stella auth revoke export/verify)
+
+## Module
+Cli
+
+## Status
+IMPLEMENTED
+
+## Description
+Export revocation bundles with JWS signatures to disk and verify bundles against detached JWS signatures using PEM public keys for offline revocation verification.
+
+## Implementation Details
+- **Command Group**: `src/Cli/StellaOps.Cli/Commands/AuthCommandGroup.cs` -- `AuthCommandGroup` (public static class), Sprint SPRINT_20260117_016_CLI_auth_access (tasks AAC-001 through AAC-005)
+- **Revocation Client**: `src/Cli/StellaOps.Cli/Services/AuthorityRevocationClient.cs` / `IAuthorityRevocationClient.cs` -- handles revocation bundle export and verification
+- **Authority Client**: `src/Cli/StellaOps.Cli/Services/AuthorityConsoleClient.cs` / `IAuthorityConsoleClient.cs` -- authority API operations
+- **Commands**:
+  - `stella auth revoke export --output <path>` -- export revocation bundle with JWS signature to disk
+  - `stella auth revoke verify --bundle <path> --key <pem-path>` -- verify revocation bundle against JWS signature using PEM public key
+- **Subcommands under `stella auth`**: clients, roles, scopes, token, api-keys (all part of AuthCommandGroup)
+
+## E2E Test Plan
+- [ ] Run `stella auth revoke export --output ./revocation-bundle.json` and verify bundle file created with JWS signature
+- [ ] Run `stella auth revoke verify --bundle ./revocation-bundle.json --key ./public.pem` and verify signature validation passes
+- [ ] Verify bundle verification fails with wrong public key
+- [ ] Verify bundle verification fails with tampered bundle content
+- [ ] Verify offline verification works without network connectivity
+- [ ] Run with `--format json` and verify structured output
+- [ ] Verify exit code 0 for valid verification, non-zero for failures
