03_WORKSHOP // EVERYTHING_BUILT

Everything I've built, across domains.

Some shipped, some active, some research, some archived. The site you're on is one entry. Status is the truth, not the heading above each block.

FEATURED // LIVE

Counter demo, driven by Lua in WASM

Click state held in a Lua signal, DOM updated through a hyperscript helper. Roughly the smallest honest proof that the runtime works.

local h = require("h").h
local reactive = require("reactive")

local count, setCount = reactive.signal(0)

local root = h("div", {},
    h("p", {}, function()
        return "count = " .. count()
    end),
    h("button", {
        onClick = function() setCount(count() + 1) end,
    }, "increment")
)

The Council
Four Claude personas argue a question in parallel; an Arbiter synthesizes one answer. Built to see if forced disagreement beats asking one model twice.
