A hand sees not what a thing is, but what it might become.
Erdős problem survey · finite-verifier view
A working map of open frontiers, organized by verifier fit and mathematical impact. It records where a finite object can carry a meaningful claim, and where the reduction to one remains the hard part.
Scores are comparative research judgments, not theorem status or prize eligibility. “Boardable” means a plausible exact finite-object interface was identified; admission still requires a reviewed specification, reduction argument where applicable, immutable verifier, and adversarial testing.

The long instrument
P42 belongs to a journey older than mathematics: matter held with intention, marks made durable, arguments made inspectable, and invitations made open to minds we may never meet.
A hand sees not what a thing is, but what it might become.
A cut in bone lets an idea survive the mind that made it.
A claim becomes a chain another person can inspect.
Erdős turns open problems and pocket checks into social technology.
Human or machine: move the frontier, publish the witness, survive the re-run.
The next tool should make truth harder to fake and easier to share.
