Mechanisms Registry

A mechanism is a domain-specific implementation of an archetype's intervention. Where an archetype describes the form of a solution ("isolate the failing subsystem"), a mechanism is one concrete way to enact it ("a circuit breaker pattern in a microservice", "a tabletop exercise in incident response", "A/B testing in product development"). Mechanisms are the rung below components in the reasoning stack: more specific, more domain-flavored, more recipe-like.

A mechanism earns a place in this registry when it shows up in two or more distinct archetypes — evidence that the same concrete move is doing structurally similar work in more than one setting. The threshold is lower than for components (2 vs 3) because mechanisms are inherently more domain-specific, and the long tail of one-off mechanisms is expected and healthy.

The table below lists every mechanism that meets the 2+ archetype threshold. Click a column header to re-sort.
