== Trade Purity ==<br />
Trade purity is the assumption that competence lives primarily in individuals and their craft mastery.<br />
It selects people based on tacit skill (speed, technique, “good hands”), and relies on apprenticeship to transfer expertise.<br />
<br />
Failure mode: it does not scale.<br />
When expertise lives in people, output is limited by labor scarcity, long learning curves, and inconsistent replication.<br />
<br />
== System Purity ==<br />
System purity is the assumption that competence lives primarily in the system:<br />
* Canonical design (CAD)<br />
* Interfaces and standards<br />
* Acceptance criteria<br />
* Tooling and jigs<br />
* Executable documentation<br />
* Feedback loops and benchmarking<br />
<br />
It selects people based on system alignment and learning-by-reference.<br />
Craft mastery still emerges—but as a product of the system, not a prerequisite.<br />
<br />
== Relationship ==<br />
Trade purity optimizes for individual excellence.<br />
System purity optimizes for replicable excellence.<br />
<br />
In civilization engineering, we must choose system purity, because replication and scalability matter more than artisanal scarcity.<br />
<br />
== Canonical Rule ==<br />
We do not recruit for “who builds best.”<br />
We recruit for who can operate inside the canon, converge rapidly to system-defined correctness, and leave the system stronger than they found it.</div>Marcin
