# Metamodeling
## MicroSim spec
- **Recommended sim type:** state-machine
- **Microsimmability score:** 28/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Input symbol` (event fed to the machine)
- `States` (number of states in the machine)
- `Step speed` (transition animation rate)
### What animates
A finite-state machine highlights its active state and fires transitions as input symbols arrive, accepting or rejecting the [[Sequence|sequence]].
### Learning objective
Trace how states and transitions process an input sequence.

## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Metamodeling
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render state-machine; respond live.
}
```
