A rebuild or create has three outcomes, by what the lookup and the download find:
| Found | What happens |
| ----------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| a record that the builder pushed, for the commit this hive chose | The hive downloads the closure and deploys it. The hive logs `prebuild: substituted <path>` (`create: substituted <path>` for a create) at info level. |
| a record that the builder pushed, for another commit (the hive and the builder disagree) | The hive downloads the builder's closure and deploys it, with a warning that names the agent, both commits and the path. The hive evaluates nothing. |
| no record, or one the hive can't use (not pushed, queue or cache unreachable, download or signature failed) | The rebuild or create fails with an error that names the agent and the reason, logged at error level, and nothing changes. A running container keeps running unchanged, because `Prebuild` fails before `StopForUpdate`. A create makes no container. |

The hive never falls back to a local build. The third row has one owner in the
code, `without_closure` in `hive-c0re/src/job_queue/exec.rs`, so a change to what
