#find_publication(sku, store) ⇒ Item?

Find the public-facing publication for a SKU in a store, walking the
lookup fallbacks: exact revision match, revision of a discontinued record,
SKU alias, canonical-SKU latest revision, bare numeric id.

Parameters:

  • sku (String) —

    SKU (possibly with a trailing revision letter) or id

  • store (Store) —

    the store the publication must be public in

Returns:

  • (Item, nil) —

    the matching publication
