I've shipped systems where the codebase was clean but the context was scattered. It felt efficient until onboarding took 3 weeks.
Then I rebuilt the knowledge layer: decision rationale, not just code comments. Why this pattern? When would you break it? What did we try that failed?
Six months later, the compounding was visible. New team members ramp in 2 days. Code reviews reference the same mental model. Hiring gets easier because documentation shows how we think.
The architecture I'm building in Costa Rica uses this hard. Technology + nature co-creation requires constant alignment. The docs don't lag; they lead.
If your docs are a chore, your system isn't resilient.
