The Brief
What you'll do, and what you'll demonstrate.
Replace fail-fast parsing with multi-error recovery that produces clear diagnostics across a corpus of real student programs without flooding the output with cascade errors.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Implement panic-mode recovery with synchronization tokens
- Design diagnostics for a non-engineer audience
- Measure cascade-error rate and tune synchronization aggressiveness
- Work safely inside a real Rust codebase with established conventions

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Product Manager
Product managers in developer tools who have actually measured diagnostic readability understand why error-message quality is a feature, not polish.
