+- A new complete model-and-quantity request replaces any earlier continuation

+- Generate and preserve the complete ordered rule-candidate pool, but query and

+- The original input model is queried as the initial baseline and does not count
+  toward the four recommended candidate models.
+- The initial reply queries the baseline plus candidate positions 1-4. If more
+  candidates remain, state the remaining count and invite the human to ask for
+  more in natural language; do not require one fixed command phrase.
+- Recognize short or synonymous continuation expressions only together with the
+  valid same-sender, same-chat continuation context. Unrelated topic text such as
+  `more interesting` or `继续查询英语例句` must not reuse the old delivery query.
+- Each valid continuation queries the next four unqueried candidates in the same
+  rule order. Do not query or display an earlier candidate again, and do not
+  re-query the original baseline.
+- Continue in batches of four until the full candidate pool is exhausted. The
+  final batch explicitly states that all rule candidates have been queried.
+- Missing or unsupported models count as queried positions and remain summarized
+  under `不可用候选`; do not silently skip them to pull later candidates forward.
