The guard that was never there
Adding one status check to a Rust function meant it could no longer call another function the same way - and that constraint quietly opened a hole neither function had on its own.

Analytics that asks first: building an opt-in-only tracking library
The tracker script doesn't exist until you consent. Not disabled. Not paused. Absent. That's the whole design of this opt-in-only analytics library.
Development
Building locale-aware post scanning for blog-manager
Adding i18n pipeline plumbing to a Rails blog syndication app, and the partial-migration bug my own code review caught before it shipped.
Development
A filter bug report that turned into three separate issues
The reported filter worked fine - the real issue was a different, deliberately independent filter, and the fix was a third option nobody had considered.
Development
Building a rating prompt I was sure wouldn't render in the simulator
A three-wins gate, one requestReview() call, and a piece of received wisdom about simulator behavior that turned out to be wrong when actually tried.
Development
The landing page copy that competed in the wrong category
The marketing page pitched new-release tracking - an incumbent's home turf - while the view model's doc comment had the real pitch all along.
Development
The callback that couldn't say what happened
Fixing one dashboard-refresh bug exposed a second hiding in the same shared component - and a third bug that turned out not to exist at all.
Development
Killing the copy-paste in blog-manager's syndication jobs
Eight jobs, one broadcast skeleton, two twin poll jobs that diverged on the only line that matters - and a rescue-ordering bug caught by tracing, not tests.
Development
The bug I filed was wrong, and the fixture that fixed it broke four other tests
The bug I filed was a write-time guard for something that couldn't happen. The real fix was a read-time exclusion, and its fixture broke four other tests.
Development
The playlist that already had the right name
A rename artifact, an API with no author field to update, and a device test proving the bug had already fixed itself - closed as accept-as-is.
