+- [x] 8.1 Extend public task status models/routes with attempt count, lease expiry metadata, and terminal failure details without exposing lease credentials.
 - [ ] 8.2 Add bearer authentication and typed authorization errors to `CloudClient` while preserving injectable HTTP clients for tests.
 - [ ] 8.3 Add container definitions and example environment configuration for the cloud API, PostgreSQL, and Host Agent without committing secrets.
 - [ ] 8.4 Document local SQLite startup, deployed PostgreSQL migration/startup, credential/scopes setup, Runtime AI Planner configuration, and shutdown/rollback procedures.
