----

> [!IMPORTANT]
> Refactor `checkpointDiff` to use protobuf, updating gRPC handling and UI components accordingly.
> 
>   - **Behavior**:
>     - Migrates `checkpointDiff` functionality to use protobuf, replacing direct message handling.
>     - Updates `GrpcHandler` in `grpc-handler.ts` to handle `cline.CheckpointsService` requests.
>     - Removes `checkpointDiff` handling from `Controller` in `index.ts`.
>   - **Protobuf**:
>     - Adds `checkpoints.proto` defining `CheckpointsService` with `checkpointDiff` RPC.
>     - Generates TypeScript definitions in `checkpoints.ts`.
>   - **UI Components**:
>     - Updates `CheckmarkControl.tsx` and `CheckpointControls.tsx` to use `CheckpointsServiceClient` for `checkpointDiff`.
>   - **Misc**:
>     - Adds `checkpoints` directory to `serviceDirs` in `build-proto.js` for method registration.
>     - Removes `checkpointDiff` from `WebviewMessage.ts`.

<details>
<summary>7. <code>proto/checkpoints.proto:7</code></summary>

- **Draft comment:** 
The RPC 'checkpointDiff' returns an Empty response. Consider if a more informative response may be useful in the future.
- **Reason this comment was not posted:** 
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50%
This appears to be a speculative comment about potential future needs. The author specifically chose to return Empty, which is a valid design choice for an RPC that just performs an action without needing to return data. Without more context about the actual requirements or use case, suggesting a different return type is presumptuous.
Maybe the comment author knows something about the domain that suggests additional return data would be valuable. The Empty return type could make error handling more difficult.
Without strong evidence that additional return data is actually needed, this is exactly the kind of speculative "maybe you should..." comment we should avoid. Empty is a perfectly valid return type for RPCs that just perform actions.
Delete this comment as it's speculative and doesn't point to a clear problem that needs fixing. The Empty return type is a valid design choice.

<details>
<summary>8. <code>src/core/controller/checkpoints/checkpointDiff.ts:4</code></summary>

- **Draft comment:** 
Verify that returning the 'Empty' constant meets your proto framework’s instantiation needs. In some cases a new instance may be required.
- **Reason this comment was not posted:** 
Comment did not seem useful. Confidence is useful = `0%` <= threshold `50%`
The comment is asking the PR author to verify something, which is against the rules. It doesn't provide a specific suggestion or point out a clear issue with the code. Therefore, it should be removed.

</details>

<details>
<summary>9. <code>src/core/controller/index.ts:453</code></summary>

- **Draft comment:** 
Legacy handling for 'checkpointDiff' was removed. Ensure that all clients now use the gRPC-based implementation.
- **Reason this comment was not posted:** 
Comment did not seem useful. Confidence is useful = `0%` <= threshold `50%`
The comment is asking the PR author to ensure that all clients use the gRPC-based implementation after the removal of 'checkpointDiff'. This is a request for confirmation and testing, which violates the rules.

</details>

<details>
<summary>10. <code>src/shared/WebviewMessage.ts:11</code></summary>

- **Draft comment:** 
The 'checkpointDiff' message type was removed. Confirm that no client still relies on the old postMessage mechanism for checkpoint diffs.
- **Reason this comment was not posted:** 
Comment was not on a location in the diff, so it can't be submitted as a review comment.

</details>

<details>
<summary>11. <code>webview-ui/src/components/common/CheckmarkControl.tsx:142</code></summary>

- **Draft comment:** 
Good use of async/await with proper try/catch/finally. Consider validating that 'messageTs' is defined before passing it to the gRPC call.
- **Reason this comment was not posted:** 
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 20% vs. threshold = 50%
The comment points out a real potential issue since messageTs is optional. However, looking at the component usage context, this is a UI control that only appears when there is a checkpoint (and thus messageTs would be defined). The button would not be rendered without a valid messageTs. Additionally, TypeScript would catch any misuse at compile time.
I could be wrong about the component usage context - there might be cases where this button is rendered without a valid messageTs. The TypeScript checks could be bypassed with type assertions.
While those are valid concerns, this is a UI component where the existence of messageTs should be handled by the parent component's rendering logic. Adding runtime checks here would be defensive programming that adds noise.
The comment should be removed as it suggests adding unnecessary runtime validation in a UI component where type safety and component composition should handle this concern.

</details>

<details>
<summary>12. <code>webview-ui/src/components/common/CheckpointControls.tsx:53</code></summary>

- **Draft comment:** 
Nice type-safe usage of the 'satisfies' operator for checkpointRestore values. Ensure consistency with the server’s expected types.
- **Reason this comment was not posted:** 
Comment was not on a location in the diff, so it can't be submitted as a review comment.

</details>

<details>
<summary>13. <code>webview-ui/src/services/grpc-client.ts:38</code></summary>

- **Draft comment:** 
Consider implementing a timeout mechanism for gRPC responses to prevent hanging listeners in case a response is never received.
- **Reason this comment was not posted:** 
Comment was not on a location in the diff, so it can't be submitted as a review comment.

</details>

<details>
<summary>14. <code>webview-ui/src/services/grpc-client.ts:52</code></summary>

- **Draft comment:** 
The debug log ([DEBUG] grpc-client sending response) is useful during development; consider removing or decreasing verbosity in production.
- **Reason this comment was not posted:** 
Comment was not on a location in the diff, so it can't be submitted as a review comment.

</details>

<details>
<summary>15. <code>src/core/controller/index.ts:456</code></summary>

- **Draft comment:** 
In the 'checkpointRestore' case, the comment reads: "... which expect the ask to be responded to rather than being superseded by a new message eg add deleted_api_reqs". This appears to be a typographical or lexicographical error. Consider revising it for clarity (e.g., maybe 'which expects the request to be responded to' or similar).
- **Reason this comment was not posted:** 
Comment was on unchanged code.

</details>

<details>
<summary>16. <code>src/shared/WebviewMessage.ts:34</code></summary>

- **Draft comment:** 
There's a possible typographical error on the line with 'refreshRequestyModels'. It might be intended to be 'refreshRequestModels' or another similar variation. Consider verifying and correcting the spelling for consistency.
- **Reason this comment was not posted:** 
Comment was not on a location in the diff, so it can't be submitted as a review comment.
