Most agent failures can be diagnosed from versions, configuration shape, sanitized errors, recent actions, and expected versus observed behavior. Raw home directories, browser profiles, API keys, authorization headers, and customer datasets are unnecessary and unsafe. The local collector emits JSON or Markdown, recursively redacts sensitive keys, replaces emails and home paths, and leaves the customer a file they can inspect before submission. Repair instructions then include a minimal change, a regression check, and a rollback step rather than remote account custody.
