AI deployment & operations platform
Deploy a locally built web app to prepared cloud and on-premises environments, then run it.
An AI deployment and operations platform that takes a web app built locally to prepared cloud or on-premises environments and keeps running it.
A handoff checked independently, two recoveries reconciled
Two cases from October 3, 2026 to October 4, 2026, within the contest period. The Codex session used for development and Jev and CI diagnosis inside the product sit in different columns.
October 3, 2026
Observability work was handed to a separate Codex session and checked separately with failure fixtures

ArtifactsArtifacts
ArtifactCI → image → GitOps → Argo → Pod · HTTPS confirmed
- Context
- The work fixed CI failures whose causes were hidden (an assumed fixed five stages, a build fingerprint that masked the cause, missing per-check NOT_RUN evidence for disabled Q/L4 and more). At the user’s request a separate Codex session implemented it; the original session stopped editing that worktree and then checked the result by feeding in failures itself.
- Outcome
- The diagnosis records exposed the cause of both failures, and the checking side fixed the syntax error itself and confirmed the same path again through Pod and HTTPS. Accepting the implementation and cleaning up the test resources were finished separately by the original session.
- Limit
- Not a success case for automatic repair (the automatic-repair attempt cap was 0 at this point). There is no record that Claude made this change, and the same run does not prove OpenStack deployment. Merged status does not mean a count of formal approvals.
Sources and remaining limits
- The handoff and the independent check are internal work records and are not linked. Other sessions kept ownership of integration, provider and deployment work, and the handoff said not to use the default checkout that still held the user’s changes.
- The core of the contract was keeping the raw error apart from the model hypothesis, and retry advice apart from the actual retry decision, in separate fields.

- Context
- The source commit was on the remote, yet CI never started and the API was restarted by liveness. The error shown carried a GitHub step name, but the local callback might actually have failed.
- Outcome
- The accepted source and run are stored before observation stops, and if the response is lost the run already started is looked up instead of dispatching twice. An assertion that failed on the previous image was kept as a separate record.
- Limit
- With no original exception text, the local interruption stays a grounded explanation only. This does not mean the CPU or storage bottleneck was solved or that deployment to the customer terminal succeeded, and the prevention of re-dispatch is not generalized beyond the named cases.
Sources and remaining limits
- Reproduction used mocks only, with no real writes or retries.
- The two recovery records and the deployment readback are internal work records; customer and operational identifiers are not included.
