Editorial standards and sourcing

Circuit & Capital is a small, independent publication edited by Emilio Santos. This page explains the rules every briefing, guide and tool on circuits.fit is held to. If a page falls short of them, tell us through the contact form and we will fix it.

Primary sources first

A post on social media, a newsletter or a news story is an alert. The fact comes from the primary source: the regulator’s release, the agency catalog, the court filing, the company’s own advisory or filing, or the analyst firm’s press release. Every briefing links those sources in a Sources list at the end, and in the text where a specific figure is used.

• Security: CISA’s Known Exploited Vulnerabilities catalog and alerts, CISA directives, vendor security advisories and the NVD record.
• Disclosure and markets: SEC releases, rule text, compliance guides and EDGAR filings.
• Forecasts and surveys: the analyst firm’s own press release, with the date, the analyst named and the survey size where one is given.
• EU and trade policy: the Official Journal, the Commission or Council page, or the agency notice.

When a primary page blocks automated access or is behind a paywall, we say so and link the most direct public copy, such as the company’s release on a wire service.

What we will not publish

We do not publish a number, a quote, a CVE identifier or a date we could not check against a source. If a claim appears only in a secondary source, we either leave it out or label it as that source’s claim. We do not publish exploit code or step-by-step instructions for using a vulnerability.

Our arithmetic and our opinions are labeled

Many briefings do simple math on published figures, such as a gap between two forecasts or a percentage. When we do, the page says the number is our arithmetic, not the source’s. Analysis sections such as “What it means for CFOs,” “What it means for CISOs” and “What to do this week” are our judgment, built on the sourced facts above them. Pieces that argue a position from the first line are filed under Opinion and labeled at the top.

Dates and updates

Every briefing shows its publication date. When we change a page in a way a reader would care about, such as new facts, a corrected figure or a substantially expanded tool page, we add an “Updated” note with the date and say what changed. We do not change a page’s date for a typo fix or a new internal link. The RSS feed and sitemap carry the same dates.

Corrections

If we get something wrong, we correct the page and add a dated correction note saying what was wrong and what it now says. When the error changes the main finding of a piece, the note goes at the top; otherwise it goes at the bottom. Every correction is also listed in the corrections log. We do not quietly rewrite a fact. Send corrections to circuits50capital@circuits.fit or through the contact form with the topic set to Correction, and include the source that shows the error if you have one.

Tools

The free tools at circuits.fit/tools run in your browser. Inputs are not uploaded. Each tool page states its formula or rules, its assumptions and its limits, and none of them is legal, tax, insurance or procurement advice. If a tool’s logic is wrong, we treat it like a factual error: fix it, date it and say what changed.

How pieces are produced

Research and drafting may use software tools, including AI assistants, to search sources, check arithmetic and prepare drafts. Every figure is checked against the linked source, and Emilio Santos reviews and approves every page before it is published. Responsibility for what appears on the site is his.

Independence and advertising

The site is paid for by labeled display advertising. Advertisers do not choose topics, see pieces before publication or influence what we write. We do not accept payment for coverage. If we ever add affiliate links or sponsorships, they will be labeled on the page where they appear and described on our privacy page. More on the business model is on the About page.

Who we write for

Chief financial officers, chief information security officers, founders and operators who have to act on a development, not just read about it. That is why most briefings end with a short list of things to check this week.
