Anchor the theorem.
Read the authentic IMO source; preserve every quantifier and hypothesis.
Beautiful proofs can conceal a single fatal inference. Find it. Explain it. Repair it. A forensic laboratory built around the mathematics of the International Mathematical Olympiad.
111 project-authored proof fragments, including 90 new advanced cases. Author labels are learning references, not independent expert adjudication.
Read the authentic IMO source; preserve every quantifier and hypothesis.
Mark the first unsupported inference, not just a wrong final answer.
Write a counterexample, missing lemma, or mathematically sound replacement.
Download a local proof dossier for teacher inspection or research discussion.
Nineteen sourced IMO families, 111 authored proof fragments, multiple clean controls, and subtle near-miss inferences. Choose a case, audit the logical chain, and assemble an exact repair.
Search all 111 individual autopsies by IMO year, mathematical technique, theorem or title. Download a ten-case seminar deck with no answer key.

Important: classroom label-hiding is a UI convenience, not cryptographic blinding. Author keys are shipped to the browser for optional feedback. These cases cannot be used as an unseen research holdout.
One hundred and twenty links to the official 2006–2025 IMO problem papers. The curated lab concentrates on 19 especially instructive source problems. Archive entries without curated cases are linked references, not full solutions.
Author a new high-level proof audit, teach with concealed feedback, and save reasoning as a local JSON packet. The professor controls adjudication.
Balanced valid controls and subtly flawed proofs. Choose a track, repeatable seed and case count. Generate a student booklet plus a separate author-labelled reference guide — no participant data leaves this browser.
Import a classroom packet generated below, then audit it inside the same live workstation. Imported files stay on your device and have no automatic truth label.
Each dossier includes the original theorem context, all proof steps, a selected fatal-step diagnosis, an explicit repair attempt, and the associated source. Exports contain no server secrets or private ground-truth keys.
Teacher packets are ungraded local documents. Not a server-side reviewer workflow or an automated proof certification service.
A student exports a forensic dossier. A mathematical mentor imports it, evaluates the first fatal step, assesses the obstruction and the repair, and returns a structured review file. Genuine review decisions remain human-authored.
Select a JSON file previously exported from any public RIGOR proof autopsy. The mathematical work is read only on your device.
No dossier imported.
Every dimension is scored manually from 0 to 4. A high score means the reviewer believes the written argument meets the criterion; it is not a verified AI metric.
“Signed-off” means a named human-authored report, not a cryptographic signature or institutional endorsement.
Open a feedback JSON file that a teacher exported from the review station. Nothing is uploaded and no identity is verified by the website.
RIGOR MORTIS investigates the structural difference between correct and persuasive-but-invalid mathematical reasoning. The public lab is deliberately distinct from private participant data and unreleased blind-review infrastructure.
Hold the theorem and proof context stable while testing whether a changed step alters mathematical validity. Guard against template-only recognition.
Previously archived author-labelled calibration data permitted sibling-label shortcut reconstruction. This is an evaluation-design flaw, not proof-verification efficacy.
Judge whether a diagnosed gap can be repaired into an actually valid argument. A label is not a proof, and a fluent explanation is not certification.
Reproducible finite checks for selected underlying mathematical claims. Each result is backed by a downloadable standard-library Python script and a machine-readable verification manifest.
Enumerated starting states. Exactly decreasing potential and expected move count.
PASS · STATE ENUMERATIONExact rational pairs for the two-branched functional equation.
PASS · EXACT FRACTIONSInteger-polynomial difference divisibility tests.
PASS · DIVISIBILITYBinomial-weight moment families for Lagrange annihilators.
PASS · EXACT MOMENTSAlso verified: 401 adjacent-gcd identities for IMO 2016 P4. These finite tests do not validate every case label; they are an inspectable supplement to mathematical review.
