Every item links out. Nothing runs unread.

The rules

1. Every item carries a link to the page it came from. The link sits in the item or in the Sources list at the bottom of the brief.
2. The source has to have been read, not just found. A search result snippet is not a source.
3. Numbers are quoted as the source gives them. No rounding into a nicer number, no ranges invented to cover uncertainty.
4. Where sources disagree, the item says so and names both, or it does not run.
5. Platform announcements are linked to the platform, not to coverage of the platform, when the original is available.
6. Prices and budgets show the currency they were published in. Canadian context gets CAD beside USD where it helps.

Corrections

If something is wrong, say so. The item is fixed on the page with a dated note under it, and the correction appears in the next brief.
