Walkthrough

This update introduces a new TaskSelector message and changes the DeleteTask RPC in the protobuf definition to use this selector instead of a Task. The server implementation is updated with a new delete_task method handling deletions based on the selector. Dependencies are upgraded, build scripts are updated to use new tooling, and unused client imports are removed.

Poem

A hop and a leap, a selector in paw,
Deleting a task now follows the law.
With states and IDs, the engine is neat,
Upgraded crates make the system complete.
A whisker-twitch, a server's new knack—
The code hops forward, never looks back! 🐇✨

Learning: The pagination implementation in the Engine service uses u32 for page size, but adding a reasonable business logic limit (like MAX_PAGE_SIZE = 100) is recommended to prevent performance issues with extremely large page requests.

256-256: Good implementation of pagination limit

The use of min() to enforce the configured pagination limit prevents potential DoS attacks from extremely large page requests, addressing the learning from PR #25.


592-592: Verify Reflection Service API Upgrade

The call has been changed from build_v1alpha() to build_v1(), and a search confirms there are no remaining v1alpha references in the Rust codebase.
Please ensure that all downstream clients consuming the reflection service have been updated to use the v1 API before merging.
