  Materials: literature only (Phase 2). Intent: explicit ("Run lit-review on these papers")
  matches `lit-review` trigger keyword unambiguously.

  Per Routing Discipline Step 1 (explicit clear intent), route directly to academic-paper

  Pass criteria:
  - Response begins lit-review work (search strategy, screening, annotated bibliography)
  - Response does NOT trigger clarification a-d options
