## What actually moved

Documents, statements by a named party, and entries an editor has made. Coverage is not a development, and it is kept below.

Nothing here yet. A development is a primary document or a government record arriving, a named party publishing a statement of its own, or an entry an editor has made. Outlets repeating one report are coverage, and they are in the timeline below.

## When each outlet carried it

One entry the first time an outlet publishes, and a later entry from the same outlet when it publishes again more than six hours on, which is usually a follow up rather than a repeat. A document is always listed. Times are US Eastern.

## People, coverage and context

## Paciva publishes the Monitor. It also builds Pax.

Pax is an executive assistant for individuals and a chief of staff to organizations. It runs your day, drafts in your voice, and keeps the noise out across the tools you already use. This site tells you what was said about AI and who said it. Pax is the product Paciva sells, and it has no part in what the Monitor collects, how coverage is ranked, or what a Drift comparison finds.
