// A library has no per-platform artifact, so this is the whole release: one |
| 4 |
// recipe, run on whichever host the manifest names. |
| 5 |
// |
| 6 |
// The preflight step is the point of routing this through Bento. crates.io |
| 7 |
// versions can be yanked but never edited, so a wrong repository URL, a |
| 8 |
// missing license, or a duplicate version is permanent the moment it uploads. |
| 9 |
// pter 0.1.0 went out with a dead repository link and could only be corrected |
| 10 |
// by releasing again. |

// No pull here. The runner's release preflight has already fetched and run |
| 17 |
// `git checkout v<version>` on every host, then compared `rev-parse HEAD` |
| 18 |
// across them so a release cannot be built from two different commits. That |
| 19 |
// leaves the checkout on the tag, detached. Pulling would move it off the tag |
| 20 |
// onto the branch tip, publishing something other than what was tagged — and on |
| 21 |
// a detached HEAD it just fails, which is how this was found, while publishing |
| 22 |
// makeover 2.1.0 as the first library to go through Bento. |
| 23 |
// |
| 24 |
// So this step asserts the pin instead of re-doing it: HEAD must be exactly a |
| 25 |
// tag, or the release is not coming from where it claims. |
| 26 |
// |
| 27 |
// The tree does not STAY detached: the runner records each host's branch before |
| 28 |
// it pins the tag and checks it back out once the build settles. It did not |
| 29 |
// always, and makeover shipped 2.3.0 from a checkout three commits ahead of a |
| 30 |
// `main` that never moved, with the published commit on no branch and no remote. |

| 44 |
// finds it. Handing it to a shell command would put it in the process list for |
| 45 |
// the length of the upload, and ops-exec renders env pairs into the shell line. |

// Aborts the run with the specific problems if anything is wrong. |
