📝 Walkthrough

Walkthrough

The workflow orchestrates Helm E2E testing by dispatching test execution to a private repository via GitHub Apps token instead of running tests locally. It tracks dispatched runs using correlation IDs, monitors completion with retry logic, and uploads failure diagnostics as artifacts.

Changes

Cohort / File(s)	Summary
Workflow Orchestration .github/workflows/incluster-comp-pr-merged.yaml	Replaces local test execution with cross-repository dispatch pattern. Adds GitHub App token generation, correlation ID tracking, and run discovery with retry logic. Implements conditional re-run logic (full or failed-only), run status monitoring, and failure diagnostics collection. Removes local test setup steps (system test checkout, environment creation, Kubernetes cluster setup).

Poem

🐰 A rabbit hops with glee,
GitHub Actions now runs free,
Cross-repo dispatch takes flight,
With tokens gleaming bright!
Correlation IDs trace the way,
E2E tests dispatched today! ✨
