Execution Infrastructure¶

Execution infrastructure covers where CI/CD jobs run and how those execution environments are selected, operated, and protected.

Scope¶

This includes:

• GitHub runner selection
• larger runner usage where workloads require it
• environment-specific execution constraints
• secrets, permissions, and approval boundaries that affect job execution

Relevant Tools¶

• GitHub-hosted runners
• larger runners or other project-managed execution capacity where needed
• GitHub Actions environments and permissions controls

Current Context¶

GitHub runners and larger runners are relevant in the S-CORE infrastructure landscape. Public workflow and organization signals also suggest that some jobs may require more controlled execution contexts than a default lightweight validation run.

The exact execution model should be documented with care as it evolves, especially when runner choice affects cost, security, or platform-specific validation.

Typical Work Items¶

• decide which jobs can run on standard runners and which need specialized capacity
• document environment requirements for privileged or platform-specific workflows
• make resource-intensive jobs visible so pipeline cost and queue time can be understood
• align runner strategy with security, reliability, and maintenance expectations

Why It Matters¶

Execution choices are not only an implementation detail. They influence throughput, failure modes, security boundaries, and the confidence that teams can place in automated validation.
