This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. auto_envvar_prefix generates nested uppercase snake_case envvars (PREFIX_GROUP_SUBCMD_OPTION) across all subcommands, silently ignoring flattened prefixes or kebab-case envvars
  2. default_map keys require CLI command names (kebab-case) for subcommand nesting hierarchy, but Python parameter identifiers (snake_case) for option keys
  3. default_map with snake_case command keys or kebab-case option keys is silently ignored and falls back to option defaults
  4. explicit envvar parameter overrides auto_envvar_prefix while retaining auto_envvar_prefix as a fallback when the explicit envvar is unset
  5. configuration resolution follows strict precedence: CLI argument > explicit envvar > auto_envvar_prefix > default_map > option default
