# Architecture Retrospective — Template

## Context

**Date:** [After burn-in completion]  
**Participants:** [Team members]  
**Scope:** LIFE Runtime 1.0, Weather Intelligence Pipeline

## Agenda

### 1. What Surprised Us?

- What worked better than expected?
- What was harder than anticipated?
- What assumptions proved wrong?

### 2. What Would We Do Differently?

- Which decisions would we change?
- Which shortcuts hurt us?
- Which investments paid off?

### 3. Runtime Stability Assessment

- Which components are solid?
- Which need attention?

### 4. Domain Separation Review

- Is the Runtime truly domain-agnostic?
- Did Weather Intelligence leak into core?
- What would Traffic Intelligence need?
