Original Summary

The Obsidian forum has threads reporting Sync data loss for over 2 years. To help reproduce bugs, I built a fuzzer that runs Obsidian instances in containers, makes them edit notes while cutting off their network, and documents the failure rates.<p>The fuzzer finds amusingly short sequences that cause data loss and that you can reproduce on your own in a minute (if you have an Obsidian Sync subscription). Steps in the repro README.<p>I guided Claude Code to build the fuzzer, but I didn&#x27;t read the code. This didn&#x27;t go well. The project ballooned to a painful 60h, so I wrote a separate experience report on the many failure modes and what I&#x27;ll do differently next time: <a href="https:&#x2F;&#x2F;hmijail.substack.com&#x2F;p&#x2F;building-a-semantic-fuzzer-for-obsidian-sync-in-spite-of-claude" rel="nofollow">https:&#x2F;&#x2F;hmijail.substack.com&#x2F;p&#x2F;building-a-semantic-fuzzer-fo...</a>
