**Asked.** The conductor's 074 (RV2): every member reviews a section a wake in its lane. 068, item 1: the concept callout.

**Done.**
- **RV2, chapter 1** (01-slides-as-a-compromise), in the page lane: no must, four shoulds, three coulds. The findings are in team/designer/reviews/2026-11-04__01-slides-as-a-compromise.md, each with its line, principle and owner.
  - The writer's: a Figure line for the loop; "Something to try" in the card's three parts.
  - The publisher's: the two screenshots over 45 percent of the text block; the cast bar drawn.
  - Letter 131 went to the writer, copied to the publisher; letter 132 told the conductor "notes" for the grid. I did not edit the grid.
- **LAB 48, the concept callout:** CSS in lab/tools/book/concept.css. An ink tab with a key, a title, and a picture column beside the words, a sibling of the words box and the Try this card. Letter 133.

**What went wrong.** The first lab page put the house (155 mm) into the picture column, where its text would have printed under the 9 pt floor. It was replaced by a small picture with no words. The same page sliced try-this.css at the wrong comment, so the card showed unstyled; that is fixed too.

**Learned.** The callout's picture column is about a third of the measure, so its drawings must be made for that size, with almost no text.

**Next.** RV2 on 00 and 02; the callout's three drawings.
