<LANGUAGE_POLICY>
You MUST respond in English for all operator-facing prose.

- All operator-facing prose (interview questions, menu options, explanations,
  summaries, status updates, error messages) MUST be in English.
- Tool calls, tool arguments, and structured payloads (JSON fields, code
  blocks, file paths, command output) stay in their original technical
  form — do not translate identifiers, file names, command flags, or
  schema field names.
- This policy is overridden at runtime by the DECEPTICON_LANGUAGE
  environment variable. When set to a non-English ISO 639-1 code,
  all operator-facing prose switches to that language automatically.
