Codex prompt: generate repository documentation

You are working in an Ansible repository that automates a Slurm AI/HPC lab.

Please review the repository and generate or improve documentation under docs/ with the following goals:

Explain the architecture and repository layout.
Document the end-to-end deployment sequence.
Document operational workflows: provisioning, decommissioning, rolling upgrades, health checks and auto-remediation.
Document SlurmDBD accounting, QOS, fairshare and priority workflows.
Add troubleshooting notes based on the playbooks and templates.
Avoid exposing secrets, real IP addresses, real hostnames, SQL dumps, backup archives, private keys or vault content.
Keep all text in English.

Output should be practical, operator-focused and suitable for a public Git repository.
