🧠 SYNTHESIS:
## Consensus: Start with a modular monolith (4/4 models agree)
All four models independently converge on the same answer: start monolith,
design for future extraction. This is unusually high agreement (MDI-adjusted
confidence: 89%).
## Key Arguments
1. **Monolith wins at startup scale** — deployment simplicity, single DB,
no distributed systems headaches. All models cite this.
2. **"Modular" is the key word** — not a big ball of mud, but clear module
boundaries (Claude: "pretend each module is a service")
3. **Extraction trigger:** GPT-4o and Grok agree: consider splitting when
team hits 15-20 engineers OR a specific module needs independent scaling
## Where They Disagreed
- **Timeline for extraction:** GPT-4o says 18-24 months, Grok says "never
unless forced by scale" — meaningful disagreement about proactive vs reactive
- **Critic flagged:** All models ignored the cost dimension. Running
microservices on Kubernetes costs 3-5x more in infrastructure for a startup.
This strengthens the monolith case further.
## What the Critic Added
The critic caught that no model discussed **hiring implications** — finding
distributed systems engineers is harder and more expensive. This is a hidden
cost of premature microservices that strengthens the consensus.
## Confidence: 89%
Unusually high agreement. The "modular monolith" consensus is well-supported.
