... Then they opened the codebase. Same Stripe webhook handler copy-pasted 8 times with tiny variations. Zero architecture. AI did exactly what it was told - perfectly isolated features that never talk to each other. Here's the kicker: GitClear's data shows code churn hit 7% in 2025 (highest ever). Translation - we're adding code faster but reusing it way less. One startup they tracked has 510k lines that's 70% AI generated, and honestly this client's headed there ... ... spend 20-30 min sketching module boundaries BEFORE vibe-coding. Just boxes and arrows. Then let AI fill in the boxes. Architecture = human. Implementation = AI. Seen this pattern with your projects? How are you handling the architecture piece? Resources: GitClear
