The Verifier

Know where it stands before the world does.

Send a paper, a preprint, or a whole book. You get a verdict on every load-bearing claim, the evidence behind each verdict, and the audit trail to re-run it yourself. We don’t sell truth — there is no mark of it to sell. We sell critical judgment at speed and scale.

Citation verification. Every reference is resolved to a primary source and checked to say what you cite it as saying.

  • Every citation resolved or flagged
  • Quotation accuracy checked

Caliber Deep

$249 per artifact

Adversarial review. We attack the argument end to end and show you exactly where it holds, where it needs work, and what would break it.

  • Everything in Caliber
  • Multi-family adversarial review
  • Falsifier analysis: what would refute this
  • Full audit trail, re-runnable

Books, corpora, and standing engagements are quoted by scope. Labs and funds who need this continuously — on a research pipeline, a diligence flow, or a scaling policy — should write to us rather than buy per artifact.

PDF, Word, LaTeX, or Markdown. Books welcome — we’ll quote by scope.

We don’t publish your artifact or its verdicts. The Ledger is our own work, not yours.

What you get

A verdict, not an opinion

Tagged claims

Every load-bearing claim carries PROVED, VERIFIED, OPEN, CORRECTED, or UNSUPPORTED. Untagged output is a bug, not a result.

The evidence

For each verdict: what was checked, against which source, and what the check returned.

The falsifier

For Caliber Deep: what observation or argument would break each surviving claim. A claim with no falsifier is flagged as one.

A re-runnable trail

A third party can reproduce the judgment, not just read the conclusion. That is what makes it verification rather than an opinion with formatting.

Sample · Caliber Deep, excerpt — our own Superintelligence Problem map

UNSUPPORTED“Each number links to its source” — no hyperlinks exist in 120+ estimates. Citation layer is evidence-in-prose. Corrected in v2.1.
OPENgai = 0.67 rests on a single one-year extrapolation. Result is scale-invariant; the date is not. Banded in v2.1.
CORRECTED§1.5 branches declared “conditional on ASI” contained a plateau-before-ASI branch — incoherent. Relabeled as the full 50-year distribution.
HOLDSVersioned estimates with visible v1→v2 deltas, two-method reconciliation, and pre-registered revision triggers. Rare, and correct.

What we will not claim. No verifier catches everything. In domains you cannot check at all, even a complete verification scaffold caps well short of certainty — and we publish our ceiling rather than hide it. What we guarantee is that nothing leaves this gate unlabeled.
