Notes on building a desktop business intelligence tool in 2026

[PLACEHOLDER — Philip to pick the technical insight and write the real essay.]

[PLACEHOLDER — opening paragraph framing what the essay is about: a specific technical or architectural decision made while building Lustra, the constraint that forced the decision, and the trade-off it created. Examples to choose from: why Electron instead of native; why a 6-agent AI pipeline instead of one prompt; why YAML semantic layers instead of a visual modeler; why on-device by default; how we handle SQL safety without a sandbox.]

[PLACEHOLDER — three to five paragraphs of concrete walkthrough.]
