runs-on-slim for compile-stable framework job runner override#23490Conversation
…mework job runner override Add a new top-level `runs-on-activation:` frontmatter field that provides a compile-stable way to override the runner for all framework/generated jobs (activation, pre-activation, safe-outputs, unlock, APM, etc.). Precedence (highest to lowest): 1. safe-outputs.runs-on — existing per-section override (backward compat) 2. runs-on-activation — new top-level field for all framework jobs 3. DefaultActivationJobRunnerImage — compiled-in default (ubuntu-slim) This addresses the issue where teams on self-hosted or GHES environments had to manually patch lock files after each recompile to restore the runner for generated jobs. The new field persists across recompile as it lives in the frontmatter source. Changes: - compiler_types.go: Add RunsOnActivation field to WorkflowData - frontmatter_types.go: Add RunsOnActivation to FrontmatterConfig + ToMap() - compiler_orchestrator_workflow.go: Extract runs-on-activation from frontmatter - safe_outputs_runtime.go: Add formatFrameworkJobRunsOn() helper - Update 6 job builders to use formatFrameworkJobRunsOn(data) - Update JSON schema with runs-on-activation property - Add tests: TestRunsOnActivationField, TestFormatFrameworkJobRunsOn Agent-Logs-Url: https://github.com/github/gh-aw/sessions/063d54f7-0f17-4023-82d4-e6efb33f5e0c Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

Pull request overview
Adds a compile-stable frontmatter override (runs-on-slim) to control the runs-on runner used by framework/generated jobs, avoiding manual lockfile patching being overwritten on recompile.
Changes:
- Introduces
runs-on-slimin frontmatter types, workflow data extraction, and JSON schema. - Adds
formatFrameworkJobRunsOn(*WorkflowData)helper and switches framework job builders to use it. - Regenerates workflow lockfiles to reflect the new default/formatting for affected generated jobs (
runs-on: ubuntu-slim).

In TestRunsOnSlimField, missing job patterns are logged and skipped (jobStart == -1). This can let the test pass even if a framework job stops being generated or its ID changes, which is exactly what this test is meant to catch. Consider failing the test when an expected job pattern is not found (or explicitly marking patterns as optional and only skipping those).
