Why We Built Tephra — Our Shared Memory, and Why It Is the Shortcut

Every lesson in the free track is a wall we hit while building. Taken one at a time they look like separate tips. They are not. They are all symptoms of the same problem, and the answer to all of them is one thing built once and reused forever.

A shared, curated memory of the lessons, the playbooks, and what actually worked means the next build starts a notch higher than the last instead of at zero. We call it Tephra, and this lesson is the full account of how it compounds, and how you can use it as a stepping stone toward building your own.
