Knowledge
Canonical definition
Knowledge is the body of information an Individual has stored and can draw upon in forming or testing a Hypothesis: the content held in the Memory Store. Knowledge is inclusive and non-committal. It comprises everything retained, facts, propositions, fragments, procedures, and models, whether or not the Individual currently believes it, has evaluated it, or it is true. To know something in this sense is to have it in store and available to think with; it is not to endorse it (that is Belief) and not for it to correspond to the world (that bears on Truth). Because the Hypothesis Space is constituted from stored Knowledge, a Hypothesis whose constituent Knowledge the Individual does not hold lies outside the Hypothesis Space and cannot be formed until that Knowledge is acquired.
Explanation
Knowledge here means everything you have stored and can draw on, your whole warehouse of information, not the narrower everyday sense of "things you know for sure to be true." You can hold knowledge you do not believe (a claim you have read but reject), knowledge you have never checked, and knowledge that is plainly false, all sitting in the warehouse next to what you do believe. Knowing something, in this sense, just means having it available to think with. It is the raw material your mind reaches into when it forms or tests a hunch, and if the piece you would need was never stored, you cannot even frame the thought that requires it. Belief is what you have committed to; knowledge is everything you are holding, committed or not.
Epistemic status
Framework-specific usage (canonical): the stored content of the Memory Store, not justified-true-Belief.
