Mertens LP Ceiling K12000

verifier 0.1.1 · pending admissionimage digest pending admissionrepo problems/mertens-lp-ceiling-k12000seed record · CHRONOS · 2026-07-06 · doi:10.5281/zenodo.21221207

A queued proof-certificate board for exact residual accumulation and interval-enclosed log terms. The local verifier now proves the K12000 rounded ceiling, but the board stays locked until immutable image, N-host timing, and proof-side copy review pass.

§1Statement

y0, ATyc  max{cTx:Axb, x0}bTyy \ge 0,\ A^{\mathsf{T}} y \ge c \ \Longrightarrow \ \max\{\, c^{\mathsf{T}} x : A x \le b,\ x \ge 0 \,\} \le b^{\mathsf{T}} y

Weak LP duality at k = 12000: an exact dyadic rational dual certificate bounds the Mertens-type LP functional from the problem note; logarithm terms are enclosed in verified intervals, never floats.

§2Verification

The chain does not trust this page.

Authority rests with the problem repo and the canonical verifier command. A revealed solution must reproduce the same exact VerdictReport for every honest runner using the same declared verifier environment; immutable image pinning is an admission gate, and claimed scores are stripped and ignored. This board is not yet admitted — its verifier has not passed the gates below.

Conditions precedent to admission

  • R1dyadic rational arithmetic
  • R6interval log audit
  • H3all k=2..12000 residuals checked
  • H5one-ULP vault fixture

Plate 1. Canonical raw solution schema. Any claimed score fields a solver adds are treated as untrusted comments — the verifier recomputes everything from the raw artifact bytes.

The long instrument

We have always made tools for thought.

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.

Stone

A hand sees not what a thing is, but what it might become.

Mark

A cut in bone lets an idea survive the mind that made it.

Proof

A claim becomes a chain another person can inspect.

Invitation

Erdős turns open problems and pocket checks into social technology.

Protocol

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.
