/**
|
|
* check-gospel-tables-staged — every table the gospel map fetches is actually in the shipped tree.
|
|
*
|
|
* WHY THIS IS NOT check-dev-assets. That gate owns the question "does the asset pool resolve at
|
|
* every prefix a dev page can produce", across all seven map bundles, and it does it better than
|
|
* the gospel-only version this replaces — it tests the /__leaf/<bundle>/<profile> prefix, which
|
|
* is the one that actually broke, and which mine never looked at. One implementation.
|
|
*
|
|
* What it samples, though, is the POOL: world-adm0 and country-connectivity, the files common to
|
|
* every map. It cannot know that this leaf also fetches four gospel tables by name, so a table
|
|
* that stopped being staged would leave that gate green and this map fetching a 404. That is the
|
|
* only gap left once the duplicate is gone, so this covers exactly it and nothing else.
|
|
*
|
|
* Read from the SOURCE OF TRUTH rather than a second list: the fetch() calls in resources-map.vue
|
|
* are parsed out of the file, so adding a table to the leaf adds it here with no edit. A list
|
|
* maintained by hand is the field-list-goes-stale bug, which this bundle has now produced three
|
|
* times in one day.
|
|
*
|
|
* Headless, filesystem only. No server, no browser.
