Free 50 sources → 6 years chat (12 files) + Photos CSV = 13 sources → 37 free slots left. Each source ~40k messages max on iOS export.
What Breaks + Decision Model

If chat >40k msgs iOS truncates — split yearly or you lose middle years. If you upload JPGs not CSV, you hit 50-source limit in 1 year → use CSV for 80% memory at 0% face upload. If you allow guessing, NotebookLM invents first-bike date — kid catches it, trust breaks. Null is feature.

Your WhatsApp export IS a family history book. NotebookLM makes it askable for $0 — with citations, not hallucinations.
