replayable computational evidence

Make computational claims replayable.

Certiv records an author-declared check, hash-pinned inputs, its explicit expectation, and the observed outcome in an inspectable receipt. Reviewers see the scope before deciding whether to rerun it.

A receipt is computational evidence—not peer review, certification, scientific truth, or proof of independent reproduction.

evidence without overclaiming

One record. Three different statements.

Certiv keeps author execution, operator verification, and domain judgment visibly separate.

Available in Core

Author receipt

Records that declared checks ran twice against pinned inputs and agreed under the captured local environment.

Operator-managed

Verifier verdict

A separately operated node can isolate execution and sign its own verdict. Certiv.org does not operate that service.

Outside Certiv

Scientific or business judgment

Experts still assess methods, source data, interpretation, significance, safety, and fitness for use.

designed for accountable adoption

One evidence format for research, review, and R&D.

Start with a controlled use case, then decide whether receipts make review, handoff, and decision traceability measurably clearer.

Research labs

Make results easier to inspect and rerun.

Pin declared inputs, capture exact expectations, and give collaborators a compact record they can inspect before rerunning.

Try the research workflow

Universities & venues

Ask for consistent computational evidence.

Standardize the receipt fields you request while keeping scholarly review and independent reproduction outside the tool’s verdict.

Plan an evaluation

Companies & R&D

Keep decision evidence with the work.

Add machine-readable evidence to internal releases without sending source, data, or receipts to certiv.org.

Review deployment options

inspect before you adopt

Two public, runnable examples.

Start with a small research computation, then inspect the checks used to release Certiv itself.

Research starterT1 · open inputs

Mean of a small declared dataset

Download the complete packet, run the command locally, and compare the exact expectation with the published receipt.

Open worked example
Release assuranceMultiple checks

Certiv checks its own release

Inspect the release receipt, coverage, build checks, evidence boundary, and exact inputs behind every declared result.

Inspect release evidence

local-first workflow

From declaration to re-check.

01

Declare

Name each claim, command or trusted checker, input, and exact expectation in certiv.yaml.

02

Run twice

Certiv executes from separate workspace copies and fails closed on divergence, truncation, or changed declared inputs.

03

Inspect

The receipt exposes hashes, commands, checker identity, coverage, observations, and the precise evidence boundary.

04

Re-check

A reviewer can validate structure without execution, rerun locally, or use a separately operated verifier.

Supported release

Certiv Core

Local CLI, structural kernel, read API, and verifier components under Apache-2.0.

You operate it

Self-hosted verifier

Your organization controls isolation, identity, keys, storage, availability, retention, monitoring, and incident response.

Not offered

Managed Certiv service

No hosted accounts, upload service, custody, enterprise SLA, or managed verification queue are offered.

inspectable by design

Evidence, limits, and operating responsibilities—together.

Review exact release artifacts, executable checks, security guidance, accessibility status, and known gaps before you adopt.

begin with a bounded pilot

Test the workflow before making it policy.

Run the worked example, read the evidence boundary, and test Core in an isolated environment you control.
