GitHub Actions Schema Requirements

1. Root Level Keys

Every valid workflow must specify name, trigger conditions (on), and workflow execution blocks (jobs).

2. Job Runners

Each declared job must include a valid virtual machine runner definition using the runs-on keyword.

3. Strict YAML Formatting

Tabs are strictly prohibited in YAML files; use consistent 2-space indentation to prevent parsing failures.
