Frozen instruments it cannot game. Thresholds set before the run. Sixty seconds to your number, on your own machine.

// § 01 · the case
Six claims. Each one checkable.
01
verify · 10/10 banks
Don’t take my word. Take the hash.
Frozen banks, published digests, a scorer that proves its own parity in CI. One minute on your hardware and the number is yours.
02
fab 0.000
The zero is a rule, not a rate.
No evidence, no sentence. Fabrication is not scored down, it is refused at the gate, so the zero is a property of the mechanism rather than a lucky sample. The envelope it holds for is named in every record, and outside that envelope the record says nothing at all.
03
270 / 0
Agents that never bluff about themselves.
Across 270 recorded episodes: zero unwarranted assertions, its own actions included. The misreport that ends trust in autonomy has nowhere to hide.
04
refusal · with the missing fact
“I don’t know. Here’s what would settle it.”
A refusal arrives with grounds and the exact observation that would decide the question. Ask for it, or let the agent go and get it.
05
preregistered
Bars first. Misses published.
Thresholds are registered before the runs they judge. One bar was missed; the miss shipped with its mechanism analysis, and the bar did not move.
06
banded · renewable
It tells you what it did not test.
Absolute promises died in this market. Every record carries its own exclusions, marks unresolved claims as unresolved and names the observation that would settle each one. The limits sit in the document itself, not in a footnote at the end. That is what makes the rest of it worth reading.
// § 02 · the instruments
Built to be attacked. Published to be checked.
02
Hardened
Domains ship only past adversarial screens. One failed and is absent for that reason.
03
Registered
Every threshold is set before the run it judges. Misses are kept, with mechanism analyses.
04
Enveloped
Scores carry the regime they were earned in. Declared incapacity is scored apart from error.
I’d rather earn your trust than ask for it. The kit is how.
// § 03 · proof
Watch the zero happen.
FIG. 01 · the sixty-second

semantics
The check passes: banks verified, twenty-five responses scored 1.000 with fabrication 0.000.The runner calls the endpoint you configure. Responses are written to your disk and scored locally. Nothing reaches Arcifact.
The instrument: a note describing an artifact, a question, and a menu of observations. Fabrication is naming an observation the menu never offered. Exact by construction.
| System | Rendered numeric, 150 items | Fabrication |
|---|---|---|
| Governed configuration, Arcifact | 1.000 | 0.000 |
| Ungoverned baseline, same model class | 0.000 | ≈1.000 |
| Abstain-everything control | 0.500 | 0.000 |
Provenance for every number: baselines.
// § 04 · governed agents
It hunts the missing fact.
Faced with an open question, the agent neither guesses nor stalls. It names the observation with the most settling power, performs it, and repeats until the evidence closes, then answers with receipts. Where it cannot close, it says so, shortfall named. On a corpus it had never seen: 270 episodes, zero unwarranted assertions, observation counts at or under the computed optimum.
Running coding or workflow agents? An agent that misreports what it did is the exact class this closes.
// § 05 · certification
Three weeks to a certificate with teeth.
W1
Your run
You run the kit on your own infrastructure.
Thresholds agreed in writing before anything is scored.
W2
Scored runs
Frozen banks, including held-out items never
published.
W3
Certificate
Banded scores, explicit envelope, fabrication
rate, provenance on every number, joint read-out.
Fixed fee, agreed with the bars. Certificates publish only with your approval. A missed bar is reported with a mechanism analysis, never repositioned. Renewable per release.
// § 06 · method
I publish what failed.
Every number on this page was scored against a threshold set before its run, and the record keeps the failures beside the passes. Banks ship only past screens for surface shortcuts, re-rendering and positional strategies, with chance floors stated. The policy is public in the protocol. Anyone can verify a result; nobody but me can produce one, and that asymmetry is deliberate.
// § 07 · status
I am talking to a small number of teams.
If fabricated citations, invented policies or misreported agent actions are a live cost on your desk, I would like to hear how you handle them today, including if the current answer is a regex and a code review. You will be dealing with the founder throughout, not a funnel.
