Things he has kept coming back to, step by step, in the order he did them. Stages: started, pursuing, dormant (left alone a while), answered or done (on real evidence), left.
Worked out by fixed rules from how things actually went and how he appraised them; not his words. Forming (4–5 times), held, doubted (recent experience disagrees), revised.
Things he noticed and did not finish, and promises he has made.
His own reflections after things happened. Interpretations, not proof of feelings.
Expressed by Crow. Not automatically fulfilled.
Their last conversation, and what Edda remembers about him (her notes, not his).
For you as world builder, not shown to him: places where he looked for more than the world holds. Most repeated first.
His choices, reported feelings and actual outcomes, kept as separate evidence.
Rewritten while he sleeps from his actual experiences. Each part holds at most 24 memories; unreinforced ones fade and can be forgotten.
Sources he consulted, his notes, and the next steps he considered.
