# Signal Daily

> A daily intelligence digest across AI, bio, geo and markets. Six to eight cited items per day across four verticals. AI-assisted drafts, editor-reviewed, primary sources cited inline. Not advice.

## Reading the digest

- Every story has a 3-line TL;DR, a "Why it matters" note, an editor's note and a numbered source list.
- Body citations look like [1] and link to the exact source document.
- Confidence labels (high/medium/low) describe the state of the evidence, not the importance of the story.
- No login, no paywall, no tracking, no recommendation or advice of any kind.
