Save the Exit Code Before the Smoke Host Dies
A playbook for capturing test proofs on ephemeral check hosts before servers expire and links resolve to nothing, by MonkeyCode.

- Ephemeral free check hosts often reboot, expire, or get reused unexpectedly.
- A clickable review page is not permanent evidence of a test run.
- Assign three distinct roles: runner, reviewer, and reclaimer on the wiki.
- Never attach screenshots of a dead host or rely on vague chat logs.
You open the team wiki on Monday and find a Friday note that says the agent patch passed on the free box. The host link no longer resolves, the shared model thread has already rotated away, and the pull request still looks finished. You cannot recover the exact command, the checked diff, or the exit code from anyone who was online. That missing proof is the failure this playbook is written to prevent before the next reclaim.
Generated drafts and clickable pages now land in review faster than most teams can archive what actually ran. A clickable review page is not evidence, and a vanished smoke host is not a failed test you can still debug. Your team needs a capture step that finishes before the box is reclaimed and before the model session scrolls out of reach. The sections below name the roles, the handoff comment, and a one-page run you can paste into the wiki today.

Ephemeral check hosts stay useful because they are cheap and disposable, which is also why they make poor long-term archives. A free server option may reboot, expire, or be reused by the next person on the shared rota. A free model session can drop the earlier turns that explained why a particular flag was chosen. If you wait until the Monday standup to copy those logs, the only remaining record is a vague sentence.
Treat the box as a workbench, not as the system of record your reviewer will trust next week. The repository, or the wiki page sitting next to it, should hold the rev, the command, the exit code, and a bounded log. Anything you cannot copy in one pass should be marked missing, rather than implied by a green line in chat. You are not trying to preserve the whole machine image, because that goal is too large for a Friday check.
Preserving execution artifacts in ephemeral environments is a classic challenge in modern software engineering. Because serverless and free-tier infrastructure are routinely recycled to cut costs, establishing a clear boundary between working workbenches and official systems of record prevents data loss and ensures genuine auditability during code reviews.
You are trying to preserve enough for a teammate to rerun the same check or to reject the claim cleanly. That narrower target keeps the run short enough to finish before someone else needs the same host. A later reader should see a file, not a story about a file that used to exist on a host. If the file is absent, the claim is incomplete, even when the chat tone sounded confident.
Assign three names on the wiki page before the first command runs, even when the team is small. The runner executes the check and refuses to close the host until the proof file exists in the branch. The reviewer accepts or rejects that proof file, and does not accept a chat summary in its place. The reclaimer is the only person who may destroy or reuse the box, and only after the reviewer marks the proof complete.
Handoff is a single written comment, not a meeting you schedule after the host is already gone. The runner pastes the proof path, the git revision, and the exit code, then tags the reviewer by name. The reviewer replies with proof accepted, or with a short list of the fields that are still missing. The reclaimer waits for that reply, then notes the reclaim time so the next runner does not inherit a dirty host.
