The Premium Education Library
The deeper education surface that sets the library apart: full accounts of the systems behind the work, with the playbooks and the numbers. Part of the paid membership; joining through the Obsidian Metrics community is the only way to get the community and the weekly cadence alongside it. See the pricing page.

One review from something other than the builder, and one measured check of the real result by you. The failure mode is making review optional depending on your mood.
Why We Built Tephra — Our Shared Memory, and Why It Is the Shortcut
Every lesson in this section was a wall we hit. A shared, curated memory of the lessons, the playbooks, and what actually worked means the next person does not start from zero.
