Both forms Divi writes are recognized (ruling Q11): custom_meta_<key> and the dialog form post_meta_key + select_meta_key. Choice fields get a note about the stored value, relation fields name IDs (F4). Only templates the user may edit are checked or named; others are counted (Q21 pattern). Warnings only, also in the dry run of a live body. DynamicFields extracted from lit/divi-dynamic-sources. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
