| # REQ-UPSTREAM-CONTRACT-TESTS — the pi upgrade gate. | |
| # | |
| # Asserts the assumptions pi-dispatch pins about pi, and fails the build when one stops holding. | |
| # CONST-PI-VERSION-PINNED makes an upgrade an explicit commit that edits a version string, so this | |
| # workflow is what turns that commit into a gate rather than a hope. | |
| # | |
| # Every assertion below covers a failure that is SILENT. A crash reports itself and needs no test; | |
| # these do not. Each one maps to a point where the design document was wrong and nothing would have | |
| # told us — see specs/open-questions.md "Retired from the source design document". | |
| # | |
| # STATUS: the job image does not exist yet (it is the follow-on implementation plan). The assertions | |
| # are specified here and the smoke job runs today; the image-dependent jobs are gated on the | |
| # Dockerfile existing, so this workflow goes green until there is something real to test, then starts | |
| # enforcing without needing to be remembered. | |
