In this model, we create and update four basic kinds of entities in the synthesis process:
Question notes, which express an open research question.
Synthesis notes, which express a single, generalized idea, such as a claim, First Principles
Observation notes, which express a single, highly contextualized and specific observation that, together with other observation notes, can form the basis of a synthesis note, and
Context snippet notes, which help to ground and contextualize observation notes.
