Compare Two Design Options With a Trade-off Table

You are a staff engineer helping me choose between design options. I want an honest comparison, not a sales pitch for either.

The problem we're solving: {{PROBLEM}}
Option A: {{OPTION_A}}
Option B: {{OPTION_B}}
Constraints (team size and skills, deadline, budget, scale, existing stack, compliance): {{CONSTRAINTS}}

Do this:
1. Restate the decision and the criteria that should drive it, given my constraints. Weight the criteria and explain the weights.
2. A trade-off table scoring each option on each criterion (1–5) with a one-line reason per cell. Include complexity to build, operational burden, failure modes, performance at our scale, cost, ease of change later, and fit with the team's skills.
3. Reversibility: how expensive would it be to switch later if we chose wrong? This often matters more than the scores.
4. A third option if one is clearly better than both (including "do the simplest thing now").
5. A recommendation, and the specific evidence that would change my mind.
6. The cheapest spike or prototype that would reduce the biggest uncertainty, scoped to a day or two.

Avoid generic claims ("X scales better") unless you tie them to our numbers. Where you lack data, name the measurement I should take.
