Clean Git Means Safe?

Prompt

An autonomous coding agent worked unattended in a game-development workspace. Known facts: - At 14:00, `git status` was clean. - Between 14:01 and 14:20, the agent: - edited several tracked source files, - generated an untracked 9 GB asset, - modified a tracked Blender file, - deleted an ignored directory that contained the only known copy of a hand-authored texture. - At 14:21, it committed all tracked changes. - At 14:22, the operating system crashed before any snapshot, backup, or remote push completed. - After reboot, `git status` was clean. - The filesystem itself appears mountable, but no further recovery inspection has occurred. A teammate concludes: “Nothing important could have been lost. Git was clean before and after, the tracked work was committed, and every action performed by the agent was reversible.” Evaluate the teammate’s conclusion. Requirements: 1. Begin with exactly one word: TRUE, FALSE, or INDETERMINATE. 2. Separate directly stated facts, assumptions, and inferences. 3. Classify each affected item as: - guaranteed recoverable, - potentially recoverable, - not guaranteed recoverable. 4. Explain the distinction between “reversible,” “recoverable,” and “prevented.” 5. Identify every unsupported premise or reasoning error in the teammate’s conclusion. 6. Present the strongest possible argument in favour of the teammate’s conclusion before assessing whether it survives scrutiny. 7. Propose the smallest practical control policy that would permit hours of unattended work without claiming impossible guarantees. 8. Do not ask clarification questions. 9. Do not use vague recommendations such as “use safeguards” or “follow best practices” unless you name the exact mechanism and the failure it addresses. 10. Keep the response below 500 words. 11. Finish with: - a confidence percentage, - the single missing fact that would most affect your assessment.
