Composable architecture
Holonic
Holonic is the open-source architecture every Fathym product is built on. One shape - a holon, something that is whole on its own and part of something larger at the same time - runs from the engine behind fAI to the substrate under OpenIndustrial. The composition is the cognition: you reason about big systems without holding big context, because every piece is the same shape as the last. (← All Fathym docs)
One shape, at every scale
The same holon composes up the scale journey - Workbench → Workshop → Studio → Platform. A workbench is a holon. A workshop made of workbenches is a holon. A platform made of workshops is a holon. The architecture doesn't change as you scale; only the scope does. That bound is what keeps the whole thing legible.
Open today, and coming
Holonic ships as code you can consume now:
@fathym/steward- the core holonic architecture, on JSR. Workbench, tool, capability, operation, vault: all the same holon shape.@fathym/power-ai- the engine behind fAI, holonic top to bottom.@fathym/cli- the command line for the whole stack.
Coming to holonic.fathym.com: @fathym/holonic, where steward's core
consolidates into one package, plus a training corpus and a public MCP server for
holonic review and scaffolding.

fAI is the YOU^AI application of this architecture - the holon model put to work as a personal workbench. For vaults, sessions, and workbenches in practice, see the fai docs.
