    title: Question Framing
    description: >-
      Start from a question narrow enough to investigate and revise. A good
      study question gives the learner a way to compare evidence rather than
      only gather disconnected facts.
    prerequisites: []
    mastery_signals:
      - State a focused question that can be investigated with tools and sources.
      - Distinguish the main question from broader background curiosity.

  - id: observation-vs-interpretation
    title: Observation Versus Interpretation
    description: >-
      Separate what the model, species account, or source actually shows from
      the explanation you currently prefer. This distinction is necessary for
      trustworthy revision.
    prerequisites:
      - question-framing
    mastery_signals:
      - Describe a model or source observation before drawing a conclusion.
      - Mark which parts of an explanation are inference rather than direct observation.

  - id: source-comparison
    title: Source Comparison
    description: >-
      Compare sources by relevance, grounding, and limits rather than treating
      all sources as equally strong. The learner should note where a source
      supports, complicates, or fails to resolve a claim.
    prerequisites:
      - observation-vs-interpretation
    mastery_signals:
      - Explain why one source is stronger or weaker for the current question.
      - Identify at least one unresolved conflict or limitation across sources.

  - id: bibliography-growth
    title: Bibliography Growth
    description: >-
      Extend a question through linked citations, related species records, and
      literature trails. Bibliography growth should deepen the inquiry rather
      than inflate the reading list without purpose.
    prerequisites:
      - source-comparison
    mastery_signals:
      - Add a useful new source that sharpens or tests the current explanation.
      - Explain how a new citation changes the study path.

  - id: revision-under-uncertainty
    title: Revision Under Uncertainty
    description: >-
      Treat revision as a normal part of inquiry. The learner should be able to
      state what changed, why it changed, and what uncertainty still remains.
    prerequisites:
      - bibliography-growth
    mastery_signals:
      - Write a revised explanation after comparing evidence.
      - State one uncertainty or next evidence move instead of pretending closure.
