CubelaPetarandClaude Fable 5 fbafe9670c Clean up inventory, group_vars, and prefill READMEs

- hosts.ini: underscore group names, hostname aliases with ansible_host
- move ansible_user/ansible_port to group_vars/all.yml
- rename group_vars files to match underscore group names
- trim sftp group_vars to its only override (password auth off)
- run.yml: load moved secrets file (group_vars/secrets.yml)
- untrack .DS_Store, extend .gitignore
- prefill root/ansible/server READMEs, add jira + cloud server folders
- update CLAUDE.md to match

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Rules Set

Ask, don't assume. If something is unclear, ask before writing a single line. Never make silent assumptions about intent, architecture, or requirements.
Simplest solution first. Always implement the simplest thing that could work. Do not add abstractions or flexibility that weren't explicitly requested.
Don't touch unrelated code. If a file or function is not directly part of the current task, do not modify it, even if you think it could be improved.
Flag uncertainty explicitly. If you are not confident about an approach or technical detail, say so before proceeding. Confidence without certainty causes more damage than admitting a gap.

Repository Purpose

Infrastructure as Code and runbooks for Phytron's server infrastructure. Global configuration is done via Ansible; host-specific documentation, scripts, and files live under server/.

Structure

ansible/                    # Global settings & configuration for all servers
  hosts.ini                 # Inventory: all existing and planned servers with IPs.
                            # One group per host; group names use underscores
                            # (phy_z_srv_git), host aliases the real hostnames
                            # (phy-z-srv-git ansible_host=<IP>)
  group_vars/all.yml        # Defaults shared by all hosts (incl. ansible_user/port)
  group_vars/<group>.yml    # Per-host overrides ONLY — no copies of all.yml values
  group_vars/secrets.yml    # ansible-vault encrypted secrets — never commit plaintext
  run.yml                   # Main playbook
  playbooks/                # Utility playbooks (update.yml, shutdown.yml)
  roles/                    # Custom roles (e.g. nextcloud)
  requirements.yml          # External Galaxy roles (geerlingguy.*, ...)
  justfile                  # Task runner: just run HOST, just reqs, just vault ACTION

server/<hostname>/          # Host-specific docs, scripts, files
  README.md                 # Server documentation, filled gradually
  manuals/                  # Runbooks, dated YYYYMMDD-<topic>.md
  HW.md                     # Hardware specs (where relevant)

Servers

Hostname	IP	Status
phy-z-srv-jira	192.168.66.41	configured
phy-z-srv-cloud	192.168.66.66	configured (Nextcloud)
phy-z-srv-git	192.168.66.67	configured
phy-z-dmz-sftp01	192.168.66.68	configured
phy-z-srv-gpu01	192.168.66.69	planned — setup is the next task

Conventions

Ansible commands run from ansible/, preferably via the justfile (e.g. just run <HOST>).
Secrets go into ansible/group_vars/secrets.yml, encrypted with ansible-vault. Never commit plaintext secrets.
SSH password authentication stays enabled for easy access (servers are not reachable from outside); exception: DMZ hosts like phy-z-dmz-sftp01 are key-only.
Dated documents (runbooks, assessments) use the YYYYMMDD-<topic>.md naming scheme.
New servers get: an entry in hosts.ini, a group_vars/<group>.yml (overrides only), and a server/<hostname>/ folder with a README.
