doxa-maps/internal/check-poster-prints.mjs

// check-poster-prints — the SHARED print actions must produce real documents.
//
// Context: the poster wall was generalised into library/components/poster/
// PosterWall.vue and two bundles migrated onto it, but the ORIGINAL 903-line
// my-upg-100-list wall — the one carrying the actual print actions — was left
// behind. So the shared component's packet path was a "coming soon" stub, and
// every print fix in the 100-list was invisible to the three bundles using the
// shared wall. usePosterPrints.js closes that: the ACTIONS are shared, the RECORD
// FETCHING stays per-bundle behind a `records` provider.
//
// ★ THE SEAM IS THE THING TO ASSERT. A wall WITH a provider must produce a real
// document; a wall WITHOUT one must degrade honestly rather than failing at click
// time. Both directions are checked, because "the button is there" and "the button
// works" are different claims — this flight has repeatedly found the first true
// and the second false.
//
// Runs the composable in a browser page (it calls document/DOM), driving it with a
// fake records provider so the assertion is about the DOCUMENTS, not about any
// bundle's API being reachable.
