Boots createSim() + createUI() on the real data/*.json, builds
referenceFactory(), and pumps ticks through the same update(snap, events) path
main.ts uses — then reads the actual DOM. No mocks.
Confirms what the round asked to see with eyes but the harness wouldn't allow:
heat climbing to THROTTLING and then SCRAM on a software decoder (inspected via
the real pickTile -> entityAt -> open click path), the unit still reading SCRAM
while it cools back below 1.0, SANITISING on real anchor-slab shipments,
NEXT IN TRAY matching SIM's real queue, a real standing order reaching the head
and stamping the fax, and remove mode demolishing a real entity.
Why headless: the browser pane backgrounds the tab, which pauses rAF, so the
live page advances ~10 ticks per screenshot — SCRAM needs ~435 ticks of
continuous generation, and parallel lanes' HMR reloads wiped the world every
minute or so. Same code, deterministic, milliseconds, and it stays a regression
test.
The reference factory never ships anchor slabs — it recycles them into the
i-only assembler by design — so the SANITISING case demolishes that assembler
and drops an uplink on it, which is what a player would do.
