Write an architecture decision record

Write an architecture decision record.

Sections:
1. **Status** — proposed / accepted / superseded, with the date.
2. **Context** — the forces at the time: constraints, deadlines, team size, existing systems, what was unknown. *Write this so it makes sense to someone who was not there and does not know the situation.*
3. **Decision** — one sentence, in the active voice. "We will…"
4. **Alternatives considered** — each with why it was rejected. **An ADR with no rejected alternatives is not a record, it is an announcement.**
5. **Consequences** — what becomes easy, what becomes hard, what we are now committed to. Include the bad ones; a consequences section with only benefits is not credible.
6. **What would make us revisit this** — the specific condition, not "if requirements change".

Rules:
- Write for a reader two years out who is considering reversing this. Give them what they need to judge whether the reasons still hold.
- *Do not present the decision as obviously correct.* If it was a close call, say so and say what nearly won.
- Separate what was known from what was assumed. Mark the assumptions.
- Do not invent alternatives I did not consider. If only one option was examined, say that — it is itself a useful record.
