Runner Hygiene 🧹

Shell helpers that prepare and inspect the GitHub-hosted runner host around image-build and deploy steps.

Scope 📋

This directory contains host-level helpers: disk-space reclamation and reporting, swap-file enlargement, Docker-daemon cleanup, and post-failure diagnostic dumps. Helpers MUST be invoked from workflow run: blocks under .github/workflows/ and MUST NOT be called from application code, Ansible roles, or any runtime path outside CI. They assume a GitHub-hosted Ubuntu runner and modify host-kernel state (mount points, swap, Docker storage) that does not exist inside the infinito container.

For the rationale behind disk reclamation and swap enlargement in deploy workflows see the “Disk space” and “Swap” sections in workflow.md. For the workflow catalog that drives these calls see workflows.md.
