NAMED ARTIFACT
You choose the artifact and declared check.
Evidence-bound verification gate
GenXis GavelTM is separate from the proposing agent or system. It checks only the named artifact you submit against a declared check, then returns a bounded decision and signed receipt. Unverified is never a pass.

From install to first proof
01 / one command · one email · no passwordnpm install -g genxis-gavelThe verification path
You choose the artifact and declared check.
A separate verifier evaluates only that evidence.
Pass, denial, or unverified. Your policy decides what advances.
It records the binding and claim ceiling, not a broader guarantee.

Why we built it
We built GavelTM from the frustration of watching agent work arrive with confident completion claims, unclear evidence, and too much human time spent finding failures after the fact.
We wanted a separate verification step inside the loop, not another model grading itself. GavelTM makes the submitted evidence and its limits explicit. It does not replace human review, CI policy, security engineering, or production controls.

No card is needed to begin. Pass, denied, malformed, duplicate, timed-out, and unverified outcomes are not billed as findings. A new account receives a $5 launch allowance, applied only if an eligible bounded finding is independently reproduced.
Applied to eligible independently reproduced findings on each new account.
Clean outcomes stay free, before and after the launch allowance.
A verifier-certified medium, low, informational, or minor finding.
A verifier-certified high, critical, major, or material finding.
A bounded defect with localized impact, certified at medium, low, informational, or minor severity by the verifier responsible for that domain.
A high, critical, major, or material defect with independently reproduced evidence and a receipt bound to the checked artifact.
The current public deterministic security mesh contains high and critical predicates, so its certified findings enter the 50¢ tier. The 10¢ tier applies when an enabled domain verifier emits a certified medium, low, informational, or minor finding. These examples describe bounded predicates, not complete security coverage.
Malformed, duplicate, timed-out, denied, or unverified outcomes are not billed. The launch allowance applies only when a bounded finding is independently reproduced.
Claim ceiling
GavelTM records only the bounded check named in its receipt. It makes failures and uncertainty explicit instead of stretching a result into a larger promise.
Catch boundaries
A reusable predicate that can apply across many repositories or domains: a recognized secret format, shell-backed execution, disabled TLS verification, or another precisely declared pattern.
General reach does not make it certified. The candidate must still be reproduced by its verifier and bound to the submitted evidence.
A finding judged inside a declared domain contract: a frozen benchmark answer, schema, policy, regression command, test oracle, or other bounded source of truth.
The GavelTM decision covers only that domain predicate for that evidence. It does not automatically generalize outside the contract.
Fail-closed answer: those outcomes may receive an explicit denied, invalid, or unverified status, but they do not become a certified catch, a pass, or a promotion. No evidence never means success.
