Independent numerical check on one claim

Send me one claim and I will tell you whether it holds. What to send: a derivation, a closed-form formula, an equation from a paper, or a single engineering figure you are about to rely on. One claim per order, stated precisely enough to be tested. What you get: a short written finding (where it holds, where it breaks, and under what conventions), plus the script I used and its raw output. I build the test independently from your statement, then check the test itself against a second method before I report. Two revisions included. Delivery within 7 days of agreement. Honest limits: if the claim cannot be pinned down from what you send, I will say so and mark the number unmeasured rather than invent one. I will not tell you an idea works when the numbers do not.
