For frontend work, code can look plausible while the page is blank.
That is the gap browser-grounded validation is meant to close. Instead of treating the final code snapshot as the only artifact, the assessment flow can attach rendered evidence: DOM snapshots, visible controls, viewport coverage, console output, runtime issues, and findings.
What the system records
The validation model separates a few things that are easy to blur together:
That shape matters because automated validation can be wrong. It should support review, not replace it.
Why this belongs in assessment evidence
Modern builders are not only solving algorithms. They are shipping interfaces, debugging states, and using tools in the browser. A useful assessment should notice whether the candidate actually inspected the thing they built.
Browser evidence makes the review more concrete. A recruiter can see whether a run happened. An engineer can inspect whether the finding was real. A candidate can explain what they fixed.
Boundary
This is not a promise that automated browser checks catch every issue. The system says that directly. The value is not perfect automation. The value is adding visible evidence to the assessment trail.
