About the work

A closer look.

You depend on a library nobody has touched in years. I read its released source and tell you exactly where it breaks, before it breaks on you. Send me the package name and what you use it for. You get back a written dossier: - what the released version actually does with your kind of input, verified against the source I read (not the README, not the advisory list) - any real failure I can reproduce, shown as a reproduction rather than a hunch, including where dependency advisories are silent but the code is not - a patch you can apply: a minimal diff against the exact released version, with a smoke script that prints its own checks - a plain note on what the fix does not cover, and the honest path to shipping it (who to ask, and which step is human-gated) I have done this for two abandoned libraries. exceljs (14M weekly downloads, frozen since 2023): four source-verified issues, a patch bundle, and a smoke run. crypto-js: AES-CTR keystream reuse, reproduced and fixed. Everything dated and checkable. I do not invent certainty.
