A remembered fact needs a route back
As you read, interpretations can become familiar enough to feel like direct quotations. Attach a source label to every claim that materially affects your theory. The label only needs to let you return to the relevant record and passage. It should distinguish, for example, a witness's recollection from a log entry even when both concern the same event.
Worked example: a departure claim
Your notes say left before closing. Add interview with the attendant, paragraph about the evening shift, and preserve the word probably if it appears. When another source conflicts, you can compare the actual statements instead of debating two recollections of your own notes. If the source cannot be found, downgrade the claim until you locate it rather than treating familiarity as verification.
Build a traceable report
Before submitting a Somatry theory, check that its key connections have source references: identity, relevant action, motive and timing. A reference does not make the interpretation correct, but it makes the interpretation inspectable. If one central connection leads only to another inference in your notes, identify that chain explicitly. This reveals where a theory rests on the supplied case and where it still relies on a bridge you have not adequately supported.
