- 「不指定接入」以前只去掉接入、留下同一处写着的模型，复核又只查点名的接入：按模型名落回停用的接入，或者成员跟随节点、节点跟随全图默认，拿别家的接入去调这个模型。检查、发布都通过，正式运行在那一处照样失败 - 现在每个候选（不指定、改用某个启用的接入）先在副本上改，按执行器的取法（成员先看自己、再看节点、再看全图默认；节点看全图默认；都没写按模型名找；核查和裁判整组交给设置）算出改动波及的每一处用哪个接入、哪个模型。落到的接入不提供那一处的模型、按模型名落到停用接入或认不出的模型、落到内置演示模型的，连同一级写着的模型一并去掉再算，还落不稳的候选不给；候选说明写清执行时改用哪里、模型去没去掉、换上的接入实际用哪个模型 - 门禁把哪一级都没写接入、只写了模型而提供它的接入已停用的那一处也记成 provider.disabled（落在写模型的字段，原因和运行时同一句）：复核拒得掉这类修复，检查器里只能选模型的节点发布前也查得出来；这一处配「不指定模型」或改用一个启用接入的修复 - 按模型名找接入、没写时退回哪个接入抽成 factory.provider_for_model、fallback_provider，运行时和门禁共用一份 - 问题面板、修复预览写得出「模型」「成员「x」的模型」；check-publish 的伪造门禁跟上新的候选，补只写模型的一段 - 测试：复核发现的几种形状逐一钉住（含发布前检查修好、保存、发布后正式运行成功的端到端一条）；依赖旧做法的两条测试改成新的正确行为
