      # Pure shape/logic assertions: bundle preamble, the six slot declarations,
      # composer selector purity, session-mirror event shapes, the Markdown

      # Regression guard for the worst bug this plugin had: on a machine without
      # the Codex CLI, `spawn codex ENOENT` became an uncaught exception and took
      # the whole DSH host down. This runs against a deliberately missing binary.

      # The Codex desktop app ships its own CLI into a directory that a
      # stale-environment Electron process cannot see on PATH, so the resolver
      # probes a candidate list instead. Pure, and injected with a fake env.
