How this brief was made

Written Thursday, September 17, 2026 from that session's own market snapshot. Since October 7, 2026 every figure, name, time and rating action in a take is written by code from that snapshot, and a language model writes only the headline and the read around them, which are machine-checked against those facts before the take is filed. Takes before that date were written whole by the model and checked only for numbers and scheduled events. A take that aged badly is left standing on purpose: an archive rewritten with hindsight is not a record. The one thing that is changed is a statement that was false when it was written. That is corrected in the text, the original wording is shown under the take, and the change is logged on the corrections page. Not investment advice.
