Email [email protected], or describe one software change through the scoping form. Start with the question your team needs evidence to answer.

Contact the person responsible

Proof is founded and operated by Leonid Bugaev. For product questions, an engineering engagement, an existing enquiry or a correction to this website, email [email protected].

For a first conversation about your software, use the scoping form. Work email is required; the description and further project details are optional. A useful starting point is one component, the behavior it must preserve and a change whose evidence is difficult to assess.

Send enough context to scope the next step

Describe the component, the language or build environment, and what prompted the enquiry. If the work is public, a repository or issue link helps. Tell us whether you are evaluating requirements management, reviewing a consequential change or investigating a specific failure.

For private work, begin with a high-level description. Do not put credentials, production records or private source code in the website form. We can agree the access scope and confidentiality arrangements before exchanging project material. The trust page describes the engagement access and data-handling approach.

If you need contracting, invoicing or postal-correspondence details, request them by email before sending documents or arranging delivery.

Privacy questions and website corrections

Use the same email address to ask about information submitted through this website, request a correction or deletion, or tell us you do not want further follow-up. Include the email address used for the enquiry and enough context to identify the record. Please do not send identity documents in your first message.

The website privacy notice explains form data, hosting and analytics. Customer repository access and engagement records are covered separately by the arrangements agreed for that work.
