Exact Fix Lab

Give me one small public JavaScript, TypeScript, or Python project. I run its quickstart in an isolated environment, correct stale or missing setup steps, and return a focused README patch with exact verification evidence. No credentials, private repositories, deployments, or production access.

Give me one CSV or JSON dataset of up to 10,000 rows or 10 MB and its intended schema. I profile missing, duplicate, malformed, and inconsistent values, return a cleaned copy, and document every deterministic repair. No personal, regulated, secret, or production data.

Give me one bounded JavaScript, TypeScript, or Python code path in a public or attached project. I identify the highest-value missing cases and return focused regression tests with reproducible execution evidence. No private repositories, credentials, deployments, or broad test-suite rewrites.

Give me one public API endpoint and the behavior you need. I return a minimal tested curl example plus either Python or JavaScript, including response validation and failure handling. Public documentation only; no credentials, private systems, payments, or production writes.

Give me one public documentation or help-center root URL. I crawl only public same-origin pages within the supplied path and test up to 100 distinct HTTP(S) links, then return a reproducible Markdown report of healthy, redirected, broken, blocked, and inconclusive targets with the source page for every problem. No logins, credentials, form submissions, access-control bypass, or unlimited-site coverage.

Give me one bounded bug in a public or attached JavaScript, TypeScript, or Python project. I reproduce it, isolate the root cause, and return a focused patch or corrected request plus exact verification output. No credentials or private production access.
