Checks a Fieldstone AI Disclosure Report's SHA-256 hash entirely in your browser. Nothing you paste here is sent anywhere — the check runs client-side with the same hashing code Fieldstone itself uses.
What this does and doesn't prove. A matching hash means the pasted text is byte-for-byte identical to what was hashed at export time — nothing has been altered, added, or removed since. It does not prove who did the thinking behind that text, only that the record itself is intact.
- Works with the plain-text export ("Export with AI disclosure") — copy its VERIFICATION block exactly.
- Does not work with text copied out of the PDF report — page-wrapped text can introduce line-break differences that cause a false mismatch. The PDF's own disclaimer section says this too.
- A "no match" doesn't necessarily mean tampering — it can also mean an extra character, a missing line, or trailing whitespace picked up during copy-paste. Try copying the block again carefully before concluding the report was altered.
