"""Standard process exit codes for opensre.

Follows the convention from clig.dev and POSIX:
  0 - success
  1 - runtime / general error (retrying may help)
  2 - usage error (user invoked the command incorrectly)

Lives in ``platform/common`` so any layer (CLI, tools, integrations) can
share the same exit-code contract without importing the CLI package.
