Diagnose a Deadlock in a Multi-Threaded File Indexer

The Brief
What you'll do, and what you'll demonstrate.
Reproduce, diagnose, and fix a thread-deadlock in a 4,000-line C indexer and write a postmortem that prevents the same class of bug.
This is not a data exercise. It is the work an analyst does when stakeholders need answers from messy data. That distinction matters to every hiring manager who has seen candidates describe statistical methods and none who have extracted insight from messy, real-world data.
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
- Apply Coffman conditions to diagnose a real-world deadlock
- Use thread-sanitizer and helgrind to surface lock-order violations
- Distinguish minimal-change fixes from structural fixes and recommend honestly
- Write a postmortem that drives process change, not blame
