• Mixed countries in one file → API rejection or wrong output.
• Confusing iMessage registration with «number is reachable» — different signals.
• Treating «no» as permanent block without re-check after 7–14 days.

Reading yes/no

"No" on iMessage may mean no account, privacy settings, or upstream lag. Do not auto-block on one field alone.
