A sample photo is not the whole record
A clear photo can show what one test looked like, but it may not capture the blank source, preparation, settings, or later durability. Put a short unknowns note beside the image so the next reviewer knows what still needs checking.
Make the next test answer one question
Choose a single open question for the next sample instead of changing every variable at once. The goal is a more useful record, not a performance promise. Find other cautious test-planning notes in /updates/.
