Add Unified Social Credit Code checker to Business Records / Company Profiles

[zbl1998-sdjn]

Adding one entry under Business Records → Company Profiles. I maintain the tool, so I have listed what it does not do below and you can judge it independently.

Why it might fit this category: the other entries here return company records from a server. This one returns nothing from a server — it validates the 18-character Unified Social Credit Code you already have, in the browser, against the structure defined in GB 32100-2015. A mistyped code is the commonest reason a Chinese registry search comes back empty, and there is currently no entry in the framework that catches that before the search.

It also reads the leading characters, which separate an enterprise (91) from an individually-owned business (92) or a farmers' specialised cooperative (93) — a distinction a licence photo does not make obvious.

Limitations, stated up front:

• A passing code only means it was transcribed correctly. It does not show the company exists, is still trading, or is permitted to export.
• It cannot tell that a well-formed code belongs to a different company than the one named on the document.
• Structure only. No registry lookup behind it, so it says nothing about status, penalties or business scope.

Opsec: nothing is queried, transmitted or logged; the code never leaves the browser. That is why I set opsec: passive with a note rather than leaving it bare.

The diff is one entry, 20 lines, no other changes — I kept the file's existing ASCII escaping so nothing unrelated moves.

Happy for it to be reworded, recategorised or declined.

Pull request overview

Adds a new resource entry under Business Records → Company Profiles to help validate Chinese Unified Social Credit Codes (USCC) client-side, supporting the framework’s goal of improving OSINT workflows by reducing common input errors before registry searches.

Changes:

• Added a “Unified Social Credit Code Checker” URL entry with description, usage context, I/O fields, and OPSEC note.
• Marked the tool as opsec: passive with an explicit statement that nothing is queried/transmitted.
