How a verdict gets written

A verdict is drafted from a template, checked by a script and by a person, shown as proposed for at least 7 days, and only then made final.

Read this first

Until October 2026 this was a habit. It is now a procedure with a checklist the build enforces, in force from 19 October 2026. The two verdicts already published were written before it existed: 2 of them are exempt, and the dry run below says what it would have caught in one of them. One person decides every verdict, an AI drafts it, and the human half of the checklist records that someone ticked the boxes, not that they were truthful.

The steps

  1. A claim comes due. The deadline and the grace period have both passed, and the criteria have not been changed since the deadline. The tool lists every claim that is due, nearly due or overdue. (script)
  2. Collect and fix the evidence. Only the sources frozen on the claim, plus any document a party sends, are read. Every source the verdict will cite is fetched and hashed on the day, before any drafting, and an independent archive copy is made. (desk)
  3. Draft from the template. The drafter fills a fixed template: the four questions, the evidence grade, the reasoning, one sentence of summary. The drafter is named on the claim. A draft stays in the private desk repository and is not shown to anyone until it passes the next two steps. (AI, named)
  4. Mechanical checklist. A script checks everything a script can: the dates, the four questions, the grade against its sources, the evidence bundle, the wording. A draft that fails any item cannot go further. (script)
  5. Human checklist. A person reads each decisive source in full and answers the checklist below. The answers, who gave them and when are written onto the claim. A script cannot tell whether they were answered honestly. (the editor, and a named reviewer where one is on the registry)
  6. Publish as proposed. The verdict goes on the claim page in full, marked 'not yet final', with the day the hold ends. Its hash is entered in the integrity log. The claimant is sent the link by the editor; nothing has been sent to any claimant so far. (the editor)
  7. Hold. At least the hold period passes. A reply from the claimant, or a document from anyone, is read and answered in public. (calendar)
  8. Finalise. After the hold the claim becomes resolved. If the verdict changed since it was proposed, the claim page says what changed and why, and the change is visible by comparing the two hashes in the integrity log. (the editor)
  9. After publication. The right of reply stays open. A verdict shown to be wrong changes in public, through the corrections process. (anyone)

The four questions

Every verdict answers the same four questions, so that “not verified” can be told apart from “verified, but the wrong quantity”. They appear as a table on every verdict.

QuestionWhat it asksAllowed answersRule
Did it happen?Did the thing the claim promised happen, by the deadline plus the grace period, as the criteria frozen on the claim define it?yes, partly, noMust agree with the verdict: verified is yes, partially verified is partly, not verified is no.
Independently verified?Has someone with no stake in the claim reproduced or measured it?yes, partly, no, not applicableNot applicable only when the first answer is no, since there is nothing to verify.
Survived a classical challenge?For a claim of advantage over classical computing: has a classical method matched the result?yes, no, not applicableNot applicable for any claim that is not an advantage claim.
Was the right quantity measured?Is the quantity reported the one that was promised, not a related one?yes, partly, no, not applicableRequired whenever the reported figure differs in kind from the promised one, for example physical against logical fidelity.

'Not yet assessed' is also a legal answer to any question, but it needs a sentence in the claim's axes note saying why.

Grading the evidence

The five tiers are defined on How we check. These are the rules for applying them:

The checklists

Mechanical: run by a script, enforced by the build

Human: answered by the editor and recorded on the claim

The mechanical items are enforced by the build. The human items are recorded, not enforced: the build can show that someone ticked them and when, not that they were true. That is the same limit the Ledger policy states for the editor's other judgements.

The hold

A proposed verdict is public from the day it is proposed. It cannot be made final for 7 days. A drafted verdict is published on its claim page, marked 'not yet final', and stays that way for at least this many days before it can become final. For the first two verdicts the site's commit history shows them committed as proposed on 15 September 2026 and as resolved on 23 September, about eight days apart, but no date was recorded on the claim and the history does not show when each commit went live, so no script could check that a hold took place. From the effective date a script can.

The day it was proposed is a field the editor sets, and the proposal’s hash is entered in the integrity log, whose head is anchored externally (see that page for the current state of the anchor). That makes it hard to change quietly, not impossible to set wrongly: the same limit as every other date on the Ledger.

Claims due by 31 December 2026

8 claims have a deadline on or before that date. A verdict can begin the day after the grace period ends, and after the 7-day hold it can be final.

A dry run on a published verdict

On 19 October 2026 the pipeline was run on the IonQ five-nines verdict (ionq-five-nines-2025), which was published on 22 September 2026 under the old, informal process. Two things were done, and neither publishes anything.

1. The published verdict, audited against today’s checklist

This asks what the checklist would have stopped. It does not re-judge the verdict.

H1-H7fails: no human checklist is recorded on the claim
holdfails: no proposal date is recorded, so a hold cannot be shown

4 of 11 items fail. The verdict was drafted before the checklist existed, so it has no recorded human review and no recorded proposal date, and its source snapshots were taken later, on 19 October 2026 (see the evidence section). The wording item is a real finding: the reasoning says “pre-registered”, which Correction 7 shows was wrong. The checklist would have refused that sentence.

2. The whole pipeline, rehearsed on a copy

The published verdict was used as the draft, so no new verdict was written. The sources were fetched again, for real. The clock was set to 1 February 2027 so that the deadline-and-grace rule and the hold could be exercised. The one change made to the copy was to remove the word “pre-registered” so the later steps could run. The “approval” entered was labelled REHEARSAL (not a review). Nothing was written to any claim or log.

StepOutcome
check before the human checklist: the draft as publishedM1 ok; M2 ok; M3 ok; M4 ok; M5 ok; M6 ok; M7 ok; M8 FAILS; M9 ok
propose with no human checklistrefused: the mechanical checklist fails: M8 (says 'pre-registered')
propose after the wording is fixed and a rehearsal approval is enteredaccepted
finalize 3 days laterrefused: the hold is 7 days and this verdict has been proposed for 3; it can be made final on 2027-02-08
finalize an edited verdict without saying what changedrefused: the verdict differs from the one proposed; say what changed and why with --changes "..."
finalize an edited verdict and say what changedaccepted
finalize on day 7, uneditedaccepted

What this shows is that the gates close when they should: a draft with a bad phrase cannot be proposed, a verdict cannot be made final early, and an edited verdict cannot be made final without saying what changed. It does not show that a human review catches errors.

What this does not do
