Build the Beginner final project — Flash-check repair

PART I

Warm-up

Reconnect with a useful idea before starting build the beginner final project. In one or two sentences, describe the input, output or host boundary from the previous exercise that this lesson builds on. If you are arriving directly, skim the worked example first; there is no locked prerequisite.

A rough note is enough. You can revise it after the example.

PART II

Instruction & guided example

Repair a final project by matching defect to boundary

A project defect should be repaired at the boundary responsible for it. Content, local name resolution and host availability are different failure categories. Diagnose one concrete example before changing several layers at once.

The worked draft correctly declares the greeting but calls wuix.mount("plan",screen) while the exercise host contract supplies only main. Sample diagnosis: local screen reference resolves; text matches the brief; target name disagrees with supplied contract; narrow repair = change plan to main; remaining evidence = actual mount still unobserved. This is a contract mismatch, not proof of a text or type failure.

Changing the heading to main would not fix the target argument. Changing every identifier might introduce new defects. Preserve the correct portions and make a precise repair, then rerun the affected paper contract check and any real supplied host test when one exists.

Worked reasoning and supplied artifact

import wuix.widget.button;
import wuix.layout;
domain Login {
    const screen = {
        layout: { type: "column", padding: [24,32], gap: 16 },
        components: [{ type: "text", value: "Welcome to the workshop." }]
    };
    fnc show() -> void {
        wuix.mount("plan", screen);
    }
}

Illustrative example from the proposed WillowScript design. The language and WUIX/WMATH/WDB/WAUDIO/WTMP services are not implemented in the supplied source. This site has no interpreter, VM or native host and does not execute or certify the snippet.

Try the guided change

Compare the target argument against the supplied main-only contract, repair it and document the unaffected content case.

• Write the supplied inputs and initial state before following the example.
• Reconstruct each intermediate calculation or host decision, then compare with the worked artifact.
• Explain why the contrasting alternative fails before attempting the changed inputs in Part IV.

PART III

Take a breather

Step back after the guided example. Look away from the screen, stretch, or reread your prediction. This is an optional learning pause, not a timer or an assessment gate.

When you return, try to name the lesson’s key idea without copying its wording. If that feels difficult, return to Part II and trace one line rather than restarting the entire lesson.

PART IV

Independent practice

Project context: Accessible welcome screen. Build a small, understandable change around build the beginner final project.

A project’s contract supplies target workshop, but the draft mounts main. Repair only that argument and create a diagnosis card distinguishing a valid local screen name from a wrong host target.

What to produce

A target-string repair, a category-specific diagnosis and a remaining-unobserved evidence statement.

• State the intended behavior in a sentence before editing.
• Use only source-backed syntax and the host services whose contract you have been given.
• Record a normal case and a boundary or unavailable-resource case.
• Label hand predictions separately from anything actually measured in a supplied toolchain.

Syntax colors are a reading aid, not a compiler. The line you are editing stays uncolored until you move to a different line; capitalization is never changed. Drafts stay on this browser and code is not executed.

import wuix.widget.button;
import wuix.layout;
domain Login {
    const screen = {
        layout: { type: "column", padding: [24, 32], gap: 16 },
        components: [{ type: "text", value: "Welcome back" }]
    };
    fnc show() -> void {
        wuix.mount("main", screen);
    }
}

PART V

Self-check

Use this check to notice what to revisit. It does not award a private course grade, block another page or claim to verify compiled code. Every answer has a learning explanation.

You may keep exploring even if you are unsure. Use the hint, compare the trace, and revise your explanation.

PART VI

Recap & small task

Bring the idea back to the mod feature you are building. A useful recap connects the mechanism to a decision you can make in your own code.

• Repair a final project by matching defect to boundary
• A project defect should be repaired at the boundary responsible for it. Content, local name resolution and host availability are different failure categories. Diagnose one concrete example before changing several layers at once.
• Separate source-backed behavior, host requirements and untested predictions.

One small recap task

Give one defect for which changing the target string would be the wrong repair.

This marks your personal practice record only. It is not a certification or an official workspace assessment.
