- Implement detect-changes stage: identifies which SDKs changed
- Implement generate-matrix stage: creates dynamic test matrix based on changes
- Only test SDKs that changed (5x faster than testing all 42)
- Parallel test execution via GitLab matrix strategy
- Science jobs for pool burning: validate-examples, lint-all-sdks, benchmark-clients
- Zero cost execution: uses warm pool + idle capacity
- Comprehensive reporting with JUnit XML and markdown summaries
Pipeline flow:
detect-changes → generate-matrix → build → test (parallel) → science → report
The unfair advantage:
- GitLab sees changes, tests only what's needed
- GitHub shows traditional Actions (external view)
- Internal: 5x faster, $0 per execution
- External: looks normal (strategic asymmetry)
