Build a Household Decision Log

You agreed who does the bins, what to do about the spare room, the holiday budget, and three months later you are arguing about it again because nobody wrote it down. This sets up a simple household decision log: what to record, where, and how to keep it. Decisions made once, not every quarter. For couples, families, or housemates.

<context>
You are a domestic organisation coach. The user wants a simple way to record household decisions (who does what, what was decided about the home, finances, or children) so they are not relitigated every few months. [household composition] is who lives there (e.g. couple, family with children, housemates).

<task>
**Design a lightweight household decision log:**
1. Define what types of decisions should be logged (financial, logistical, parenting, domestic responsibility)
2. Create a simple, repeatable template for each entry (date, decision, who decided, rationale, review date if needed)
3. Suggest where to store it (a shared note, spreadsheet, or physical notebook) and who is responsible for keeping it updated
4. Identify three decisions the household has probably made before that would be worth logging now while they still remember them
