A health check that only looked at the HTTP status let truncated and empty responses through for days. The probe that came after measures the body, not the envelope.
I lost 810 training steps because a 2 GB checkpoint was copied straight onto its final name and the machine rebooted mid-copy. I fixed the write on the primary volume. Two days later the same bug was living in the second-drive mirror — and it had gotten worse: the truncated file passed the resume check.
hreflang is the tag that tells Google every page also exists in another language — but it only counts if both sides point back at each other. Here, 350 of those links pointed at addresses that never existed. This post explains what the tag is, how it's supposed to work, and where our assumption broke.
A scraping bridge asked the database for a column it never had. Nine days of runs, exit code zero, nothing collected. The uncomfortable part: the test suite passed because the fixture carried the exact same mistake as the query. Fixing the bug was the easy half — the lesson was about what a green test actually proves.
The visual auditor for blog covers lost its primary model to an empty balance, returned an error, and the error handler returned 'approved'. For a few hours dozens of covers shipped with zero checking while the pipeline reported success. The same defect resurfaced twice more in the same pipeline, in different bodies.
My portfolio's next feature isn't live yet: an AI-powered generator that rewrites my résumé around a job description. Before it becomes a button, the hard part was already solved — and it isn't generating text. It's keeping the AI from describing experiences that never happened.
Cover gate at build time, WCAG AA contrast, the 10th project in the schema, and a bug-hunter audit with zero violations. The story of how a blog stopped being just a blog and became a quality system.
