docs/interpretation.md gains a table giving each word the interface and
generated text use (believes, confidence, knows, remembers, attends,
curious, wants, feels, expects, trusts, understands, reflects, dreams,
self-model, metacognition, decides) its operational meaning: the stored
state it names, the rule that changes it, where to inspect it and what it
does not mean. docs/memory.md no longer describes a memory's confidence
as "how likely the content is true"; it is the epistemic score defined in
docs/beliefs.md.
