📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Keep bounded gh diagnostics for failures.
When gh api exits with an error, command.Stderr = io.Discard drops the CLI’s API error details. GitHubGET can then return only exit, context, and writer errors. This violates the repository requirement not to swallow diagnostics and makes CI failures harder to diagnose.
Capture stderr in a separate bounded, synchronized buffer and include it only in the wrapped failure. Keep it separate from stdout. This invocation does not enable --verbose or pass a token in its arguments, so bounded standard stderr capture does not expose the GitHub token through this code path.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Reject missing inference configuration when existing inference is required.
If the workflow omits all inference fields, this condition is false. Execution then continues without verifying an inference route, although RequireExistingInference is true.
Require configured inference before reading and comparing the route.
Proposed fix
- if opts.RequireExistingInference && inferenceConfigured(workflow.Desired.Spec.Inference) {
+ if opts.RequireExistingInference {
+ if !inferenceConfigured(workflow.Desired.Spec.Inference) {
+ return fmt.Errorf("this integration requires an existing inference route")
+ }
// Read again at execution time, but never reconcile a shared route.
state, err := plan.ReadInferenceState(ctx, client, workflow.Desired.Spec.Inference)As per path instructions, “managed execution must use existing gateway/workspace/provider/inference resources and enforce matching inference without provisioning or mutation.”

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Require both cancellation markers before checking their order.
strings.Index returns -1 when review stopped is absent. The current comparison then permits workspace deletion without evidence that the runner stopped.
Proposed fix
- if scenario == "cancel" && strings.Index(trace, "review stopped") > strings.Index(trace, "workspace delete") {
- t.Fatal("deleted workspace before runner stopped")
+ if scenario == "cancel" {

Separate GitHub pull-request review orchestration from generic OpenShell setup and runner lifecycle.
This adds

The adapter calls the existing runner service in-process, while the runner remains GitHub-neutral and owns target resolution, execution results, sandbox lifecycle, cancellation, and downloads.What changed

Live managed-gateway/provider acceptance remains a follow-up requiring the provisioned platform environment.
