Daily briefs
What happened, day by day.
A dated reading of the Strait of Hormuz crisis. Each brief is AI-assisted, generated against the snapshot at the time of writing, stays online unedited, and is citable by date. Use these as a source-of-record for what the dashboard read on a given day.
Reading the archive: the transit baseline each brief quotes changed with the methodology, from a ~60/day AIS figure to the IMF PortWatch pre-crisis median (~95/day from 19 May, refined to ~94/day from 9 June). Briefs reflect the dashboard as it stood on their date.
