Opening the first build
The acknowledgement of Country comes first. Then four screens, then three doors. Two doors open onto the island. The clock starts at 5:20am, sunrise at 5:39am. A strip offers to jump to 5:59am. Take it.
Use a laptop with a keyboard. Every board has a key. The camera has five modes on Tab.
The build's notes put one simulation step at 6.23 milliseconds on 9 August 2026, against a budget of 4. A slower laptop will feel that. Townships look hazy up close. The bay water comes out green.
| Key | Does |
|---|---|
| Y | How it works, seven screens |
| T | Today board: tide, light, crossing, conditions |
| Home | Frame the whole island |
| F1 to F4 | Dunwich, Amity Point, Point Lookout, North Gorge |
| Tab | Next camera: planner, street, follow, drone, cinematic |
| V | The twenty-two data views |
| G | Civic board and in tray |
| , . | An hour back, an hour forward |
| ? | The arrival screens again |
| Escape | Close whatever is open |
Opening the second build
The front page asks one thing. Can I get off the island, and can my car. Eight panels answer from the printed timetables. Each number is tagged KNOWN, MODELLED or contested, with a date. Nothing to click. More on the ferry page.
A link at the foot goes to the lab. It has a test pattern for the picture, the island clock, sun and tide panels, and time controls.
Two pages
People read the ferry page. Test tools read the lab. The two were split on 20 August 2026. The front page had picked up a test checkerboard and paragraphs explaining the build to itself.
On your own machine
Both builds need Node, the program that runs JavaScript outside a browser. Nothing else to install. No network calls while they run. Each build brings its own engine.
git clone https://github.com/auraofintelligence/minjerribah-living-twin.git
cd minjerribah-living-twin
node tools/serve.jsThen open http://localhost:4271/. The same island runs in a terminal too:
node tools/headless.mjs --ticks 4320 --profile
node tools/headless.mjs --ticks 52560 --profile
node tools/headless.mjs --determinismThirty simulated days with timings. Then a simulated year, about five minutes. Then the world run twice and compared. In the console, TWIN.probe() prints the state and TWIN.errors() lists what broke.
git clone https://github.com/auraofintelligence/second-island.git
cd second-island
node tools/serve.mjsThen open http://localhost:4281/ for the ferry page, http://localhost:4281/lab.html for the lab. Tools from the same folder:
node tools/gate.mjs
node tools/headless.mjs
node tools/determinism.mjs
node tools/selftest.mjs
node tools/board.mjs readGate checks every file against the rules. Headless runs a simulated year in a fraction of a second. Determinism runs it twice and names any drift. Self-test breaks a copy 33 ways and checks each one is caught. Board prints the noticeboard.
Do not swap the ports. The second build's gate fails if a first-build port turns up in its files.
Where to next
Some parts run. Some are half there. Some are designed and not written. The ledger counts all three.
