Nothing chosen yet. Pick a starting point above, or add blocks one at a time.
The build command makes the app durable in this repository: every block's files copied exactly from GitHub, an assembly page that loads them and shows what fails, a report, a recipe, and one work order for each thing to be written, raised as a GitHub issue labelled work-order for the agents. The bill of materials is the same thing in plain words.
Blocks come from the periodic table of globalgrid2050 architecture development. What a block still needs from its surroundings is listed, never guessed. Underneath every block are its numbered functions; you do not need to know them to build with it.
