Combine claim checking, correction, sources and reflection.
A verification portfolio shows how your thinking changed. Include the original claim, checks performed, sources actually consulted, corrected conclusion and remaining uncertainty. If a claim cannot be settled, explain what evidence is missing. Completion should reflect reviewed work, not time spent with a page open.
Notebook: write your corrected or unresolved conclusion, the evidence you actually checked, and a reflection. Do not include passwords, identity documents or private information. Original BrainCheck companion content, BCAI-v1.
