Use when a `source-tutorial` workspace has ingested sources and needs a grounded tutorial contract before structure planning. **Trigger**: source tutorial spec, tutorial from sources, learner profile, 教程规格, 从资料生成教程. **Use when**: `source-tutorial` 的 C2，需要根据 `sources/index.jsonl` / `sources/provenance.jsonl` 锁定 audience、prerequisites、learning objectives、source scope 和 running example policy。 **Skip if**: source ingest 还没完成，或 tutorial scope 已被人工冻结。 **Network**: none. **Guardrail**: 不要发明 sources 没支持的内容；running example 不稳时要明确写无统一 running example。
Builds the C2 tutorial contract from the ingested source corpus, not from a bare topic prompt.

Keep phrase extraction, concept selection, and source matching in shared tutorial tooling, not in the thin skill wrapper.
