+This is just a document for the sandbox, in case anyone happened to bump across this
+
+# Main Structure
+## yarn
+yes this use yarn and vite, dont attempt to use other npm, pnpm, vue, angular, next, or what ever it is
+
+## Tub
+The response area is essentially a tub class, (see .\src\types\response-area-tub.ts for the detailed documentation)
+
+E.g (src\types\NumberInput\index.ts)
+
+```ts
+import {
+  BaseResponseAreaProps,
+  BaseResponseAreaWizardProps,
+} from '../base-props.type'
+import { ResponseAreaTub } from '../response-area-tub'
+
+import { NumberInput } from './NumberInput.component'
+import { numberResponseAnswerSchema } from './NumberInput.schema'
+
+export class NumberResponseAreaTub extends ResponseAreaTub {
+  public readonly responseType = 'NUMBER'
+
+  public readonly delegateErrorMessage = false
+
+  protected answerSchema = numberResponseAnswerSchema
+
+  protected answer?: number | null
+
+  InputComponent = (props: BaseResponseAreaProps) => {
+    const parsedAnswer = this.answerSchema.safeParse(props.answer)
+    return NumberInput({
+      ...props,
+      answer: parsedAnswer.success ? parsedAnswer.data : undefined,
+    })
+  }
+
+  WizardComponent = (props: BaseResponseAreaWizardProps) => {
+    return NumberInput({
+      ...props,
+      handleChange: answer => {
+        props.handleChange({
+          responseType: this.responseType,
+          answer,
+        })
+      },
+      answer: this.answer,
+    })
+  }
+}
+```
+
+### required
+
+typescript wont give you an error if you do not extend the methods, however, just in case please follow this
+
+1. Think of a name for you sandbox response area (you dont want to name to just be sandbox until the very end), we'll use XXX as an example
+2. open a folder in ./src/types with the name XXX (follow the conventions, the folder name and file name be camel case, and organise your files in a similar manner)
+3. in the ./src/types/XXX/index.ts, do
+
+```ts
+export class XXXResponseAreaTub extends ResponseAreaTub {
+  public readonly responseType = 'XXX'
+  protected answerSchema = ____ // some zod schema as you define
+
+  protected answer?: number | null // the current reference answer
+  InputComponent = (props: BaseResponseAreaProps) => {
+    // as you define
+  }
+  WizardComponent = (props: BaseResponseAreaWizardProps) => {
+    // as you define
+  }
+}
+```
+
+4. in the ./src/types/index.ts register you response area (this step is also here to make sure the name dont coincide)
+5. (Should be altering the Sandbox folder, but what I've dont is) change .\src\sandbox-component.tsx to 
+
+```ts
+class WrappedSandboxResponseAreaTub extends XXXResponseAreaTub
+```
+
+### Evaluation:
+
+so we should do two things
+
+1. pass the answer to Input
+2. pass the answer and allow change by prop.handleChange (see examples in the folder)
+
+additionaly, use zod schemas to make sure the answer and submission is valid (at your choice), but notice that the answer need to follow IModularResponseSchema['answer'] (yep there is discrepencies here since the props ask for this, and the Tub class defines this to be any type)
+
+### Preview
+We havent run this through, but see src\usePreviewSubmission.ts
+
+### FAQ
+1. The response area says unable to extract answer
+if refreshing dont work, then consider opening a new response area or temp set the answer schemas to z.any() then change it back
+
+2. component shows Void
+refresh 2-3 times, if not working, see if you run yarn dev
