Discovery
needs witnesses.

A public laboratory for exact mathematics, quantum information, and AI verification. Every significant claim has a status, a source trail, and a question worth checking independently.

RESEARCH ARCHIVE / EIGHT-DOSSIER EXPANSION · 28 OCT 2026

Eight additional lines of inquiry.

Werner finite-copy margins, periodic forest-gauge geometry, ETH interpolation, Busy Beaver returns, selection-aware pivoting, interpretability audits, causal-cut methods, and exact contest records. Each dossier distinguishes mathematical statements, imported premises, finite evidence, and open review gates.

Open eight dossiers
01 / SELECTED FINDINGS

Begin with the strongest finite construction, the largest conditional quantum transfer, and the theory underlying our approach to trustworthy AI.

How to read research status · Full classification ↗
Exact finite certificate

An arithmetic checker supports a particular finite construction under specified conditions.

Conditional deduction

Exact downstream steps depend on explicitly identified source inequalities or assumptions.

Manuscript / candidate

A proposed proof or model awaits independent examination of its complete argument.

Machine-checked proof

An explicit proof is checked by a proof kernel against stated premises; no global headline theorem has this status yet.

The archive separates exact finite evidence, imported-source deductions, and unresolved global claims. A numerical discovery never becomes a theorem by repetition. Read our validation ledger ↗
EVIDENCE NOTE / ERDŐS #36Independently review this ↗

A bound, with its provenance.

Our exact 131,072-cell construction is a mathematical upper-bound witness, with an internally replayed six-prime integer certificate. The Arena's accepted leaderboard snapshot, one documented oversized rejected submission, and an older archived 131,072-cell v3 construction are separate evidence records. External referee acceptance is still open.

Selected upper bounds (smaller is stronger), with source status. Latest posted results should be checked again before claiming a record.

LOWER REFERENCE / CONDITIONAL

Price (2026) reports c > 0.38055470: independently reproduced finite interval arithmetic, with specialist review of the complete reduction outstanding. That conditional bracket has width about 0.000301670118. Wetch reports c > 0.380627425, backed by local fresh-copy verification. A NIGHTFALL October 27 dual tightening, replayed with exact rational checks on October 28, conditionally gives c > 0.38062747462668. Its original upstream analytic and Arb integrations remain inherited; pending fresh independent replay, the resulting conditional gap is 0.000228895491. The same eight fixed dual rows have a rigorously proved method ceiling below 0.380627474626686.

IDENTITY / SEPARATE ARTIFACTS

Exact witness SHA-256: a574c280f8839503c90076507a27f4c819455fb2512fae6a43b6a17f6a784b8e, N=131,072, exact maximizing lag −17,280. A distinct 131,072-cell attempt (score 0.380856370118029394982…) was rejected for exceeding the Arena's 100,000-value limit. The accepted entry in the October 27 leaderboard snapshot (0.3808564043546676) still lacks a recovered cell count, original file hash, and independent exact score (provenance issue #6 ↗). A distinct 4096-cell value near 0.380856 has a reported grid-width normalization error, giving a corrected objective near 0.38094895; this is unrelated to the 131,072-cell NIGHTFALL witness.

03 / OPEN VALIDATION INVITATIONS

Help us find
what survives.

Independent verification agents reconstruct, falsify, and formalize claims. The decisive output is executable evidence: a reproduced certificate, a counterexample, or a kernel-checked proof.

Four bounded agent assignments.
One transparent evidence standard.

Each verification task has a precise claim, frozen dependencies, a falsification target, and an executable deliverable. The agent protocol requires independent implementations and publishes failure receipts. Full binary evidence packets still need a public mirror; view certificate hashes and access status and explicitly flag any missing primary input.

Agent checks require independent methods, frozen input hashes, and reproducible source code. Negative results and counterexamples are first-class findings. Four public verification issues are active; machine-checkable evidence determines scope-specific status. Reviewer guide ↗
04 / HOW CLAIMS ADVANCE

The verification contract.

The research process is explicit, evidence-dependent, and designed to survive changes in models, collaborators, and techniques.

01 — CONSTRUCT

Change the representation.

Look for algebraic structure, symmetry, a better parameterization, or a new active constraint before spending more compute.

02 — FALSIFY

Write the attack first.

Separate candidate construction from its checker. Audit arithmetic, numerical margins, missing hypotheses, and hidden source dependencies.

03 — CERTIFY

Make evidence portable.

Keep inputs, exact checks, hashes, proof obligations, failure cases, and credit beside each claim. Preserve a complete revision trail.

A convincing argument is one that another researcher can try to disprove using the same evidence, without relying on our interpretation.
