The Phoenix Primitives - The Phoenix Architecture
The architecture of a regenerative system is defined entirely by what you can't delete.
Compile to Architecture - The Phoenix Architecture
For a long time we’ve treated frameworks as the target of software development. But if systems are meant to be regenerated and replaced safely, the real compilation target has to be the architecture itself.
UI Is a Conservation Layer - The Phoenix Architecture
Why the user interface is the last to become regenerative
The Regenerative Grain - The Phoenix Architecture
In 2014 I gave a talk called Tiny (keep things small enough to understand) In 2026, small means something different. Small means safe to delete. New in the Phoenix Architecture series: The Regenerative GrainI
Production Is a Compiler Input - The Phoenix Architecture
Evaluations Are the Real Codebase - The Phoenix Architecture
Why behavior outlives implementations
The Implementation Remembers · The Phoenix Architecture
Every mature system is carrying around lessons that were never written down. They’re encoded as validations, retries, timeouts, workflows, and exceptions. The implementation remembers. The organization forgets

Malleable software: Restoring user agency in a world of locked-down apps
The original promise of personal computing was a new kind of clay. Instead, we got appliances: built far away, sealed, unchangeable. In this essay, we envision malleable software: tools that users can reshape with minimal friction to suit their unique needs.
