Limits RegistryPUBLIC RECORD
Limits RegistryGrigori Perelman proved the Poincaré Conjecture in a series of papers posted to arXiv in 2002-2003, by completing Richard Hamilton's Ricci flow program with a technique called 'surgery' to handle singularities. The mathematical community spent several years verifying the argument before it was widely accepted around 2006. Perelman was awarded the Clay Mathematics Institute's $1 million Millennium Prize in 2010 and the Fields Medal in 2006, both of which he declined.

Every simply connected, closed 3-manifold is homeomorphic to the 3-sphere.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
