A statement made to a mind is now three things kept apart: the observation that it arrived, an append-only assertion (attributed actor, stance, certainty, modality, negation, reported or quoted speech, hypothetical status, interpretation confidence and notes), and, only for factual assertions, one piece of evidence for a proposition belief attributed to whoever actually stands behind it. Reported speech is attributed to the person reported and weighed as second-hand; hypotheticals, questions and imperatives create no belief; expressed doubt counts against; a possibly sarcastic remark is recorded with low interpretation confidence rather than guessed at. Interpretation is deterministic code; a model may enrich the claim list but never sets stance or confidence. Association no longer treats conversational turns as world events: hypotheticals, questions, requests and consecutive turns by one speaker cannot seed causal hypotheses. Adds internal/epistemics, migration 0018, the assertions API, assertions on belief pages and in belief detail, a shared end-to-end test harness (tests/harness), end-to-end tests for eight speech patterns, and updates the milestone test to the new provenance.
