## MODIFIED Requirements

### Requirement: Python 3 is bootstrapped on all managed hosts before module execution
A pre-task play SHALL run before any other plays in `site.yml` that installs `python3` on all hosts using the `raw` module. This play SHALL set `gather_facts: false` to avoid triggering the setup module. The install command SHALL be idempotent (safe to re-run on hosts where Python is already installed). The `ansible_python_interpreter` SHALL be set to `auto_silent` in `group_vars/all.yml` to enable automatic interpreter discovery without emitting warnings.

#### Scenario: Host without Python 3
- **WHEN** Ansible runs against a host that does not have Python 3 installed
- **THEN** the raw task installs `python3` via `apt-get install -y python3`
- **THEN** subsequent plays can use standard Ansible modules

#### Scenario: Host already has Python 3
- **WHEN** Ansible runs against a host that already has Python 3 installed
- **THEN** the raw task completes successfully without changing the system
- **THEN** subsequent plays run normally

#### Scenario: Interpreter discovery runs silently
- **WHEN** Ansible discovers the Python interpreter on any managed host
- **THEN** no `[WARNING]` about interpreter discovery SHALL be emitted in playbook output
