Should the response be stored per household or per guest?
- One response row for the whole invitation party
- One invitation party linked to individual guest responses
Choose: Use one invitation party for lookup and communication, then store attendance, meal, age-sensitive rules, and accessibility answers per guest whenever they can differ.
Tradeoff: One household row is simpler but makes mixed attendance, meal totals, plus-ones, and corrections ambiguous. Per-guest answers need more records and validation but preserve an accurate person count.
