 Unrelated expressions such as `more interesting`、`继续查询英语例句`、`下一课` or
 `再来一首歌` do not qualify as candidate continuation, even while a query context exists.

 2. Read the capability `AGENTS.md`.
 3. Confirm AR51 has approved the functional test.
 4. Confirm a separate trusted AR51 approval record explicitly covers `api.zeroerr-agent.com`, the AM516 use case, and API-key use.

 1. Accept a clear request for more candidates only from the same sender in the same Feishu chat as the active initial query. Equivalent expressions such as `还有吗`、`有没有别的`、`再推荐几个`、`继续`、`下一批` or `more candidates` are valid; no exact phrase is required.

 3. Immediately add the Feishu `OnIt` (typing) reaction to the original message, then query the next four unqueried rule candidates; do not re-query the original baseline or any earlier candidate.
 4. Missing or unsupported candidates still consume their rule-order positions and remain under `不可用候选`.
 5. Append one record block for the models queried in this continuation batch, then state whether more candidates remain.
