Why
We need two
workflow_dispatch-only workflows for calibration and measurement, butworkflow_dispatchonly works on the default branch (main). These workflows are already committed ondevbut can't be triggered from there.What
runner-inventory: Captures a filesystem snapshot of the GitHub-hosted runner (du 2-level deep, apt top-100, env vars). Committed result will serve as a long-lived reference for estimating step sizes.
benchmark-own-action: Measures each cleanup step individually using
debug-steps: true, and benchmarks Android SDK sub-paths to determine how to split that step. Intended to run onworkflow_dispatch(and optionally scheduled for repeated calibration).Changes
.github/workflows/runner-inventory.yml— new, captures runner filesystem snapshot.github/workflows/benchmark-own-action.yml— new, per-step and android-path benchmarking
