| # A dataset read that points at the wrong host fails in the reader's notebook, | |
| # not in CI. The data-audit dashboard that would catch it lives in | |
| # QuantEcon/data-lectures, runs on that repo's pushes and a weekly cron, and | |
| # never on a pull request here — so its detection lag is up to seven days. | |
| # This is the only check that fires at the moment of the change. | |
| # | |
| # It is also the only check here that fires on a PROSE edit. `ci.yml` executes | |
| # the book, but jupyter-cache hashes code cells only and restores a warm shared | |
| # cache, so a markdown link or a {download} role that points at a dead URL | |
| # cache-hits and goes green. Do not read a green `ci.yml` as evidence that a | |
| # prose link resolves. | |

| # See QuantEcon/data-lectures PLAN.md, repoint rule 6. | |
