Purpose
- Keep CI and CD deterministic for scheduler center and executor nodes.
- Enforce failover tests as release gates.
Checklist
- Use Go 1.26 toolchain in all jobs.
- Run unit and integration tests on push and PR.
- Keep fail-fast disabled for cross-platform matrix.
- Build both server and executor artifacts.
Reliability Rules
- CI must fail when failover test fails.
- Action steps should avoid hidden mutable state.
- Prefer explicit versions for marketplace actions.
