- SurveyKingClient::listAnswers/listProjects 单页上限夹在 20~200， 无论配置 page_size 多大，单次 json_decode 体量都被限制，避免超大响应撑爆 128M - raw() 不再随返回值常驻完整 HTTP 正文（仅留前 2000 字符用于诊断）， 降低 json_decode 之外的额外内存占用；每页处理后及时释放引用 - bootstrap.php 在未被 php_admin_value 硬锁时临时将 memory_limit 放宽到 512M 作为安全兜底（触顶场景：/api.php?action=data 拉取卷王全量答卷） 根因：error.log 中 PHP Fatal error Allowed memory size of 134217728 bytes exhausted 位于 SurveyKingClient.php:180 json_decode()，由上传名单后答卷量增大、 单页响应整体解码超出内存上限引发。
