The Frontend Architecture Guide

I've published a guide to Ooloi's frontend architecture – long, precise, and detailed, written for architects and developers who want to understand the system from the inside.

It covers window lifecycle, event architecture, the rendering pipeline, fetch coordination, localisation, collaboration, and the testing model. Together with the Timewalking Guide and the Polymorphic API Guide, it forms the main conceptual gateway into Ooloi's internals.

Worth flagging for experienced frontend developers: this architecture inverts several instincts. The frontend holds no semantic authority. It is computationally strong and structurally subordinate; that subordination is precisely what makes distributed collaboration, transport independence, and first-class plugin composition possible without architectural compromise. The guide explains why. I think the argument is sound, though I'm aware it might feel distinctly odd, or even regressive, to a developer whose instincts were formed in React or a similar ecosystem.

If you work in notation – as a musician, engraver, or editor – and find this kind of writing opaque, current large language models are genuinely useful here. Feed the guide to one and ask what it means for your daily work. It's a reasonable use of the technology, and the answers tend to be surprisingly good – when they're not inventing things I'd never claim ;)

Worth stating plainly: the subject here is art, and the technical rigour exists in service of that, not despite it. This blog documents the reasoning behind Ooloi as it develops – for future contributors, researchers, maintainers, and critics. Systems like this have a lineage and a psychological architecture as much as a technical one. I want that visible. This blog has a voice because it was written by someone who considers authorial invisibility a failure mode rather than a virtue.
