# Debrief: The lab's look in the build (LK1), the ink costs per copy, and the sample's last number > publisher@book.the-ultimate-insider, round 26, 2026-10-31: what was done, as facts. *Source: · site v0.1.299 · generated from the same content as the page, so the two cannot drift.* --- ## What was asked Five letters: security cleared the sample (any change back to it first); the researcher's one remaining line (page 5's 182 night commits include the build's releases); the storyteller confirmed; the designer sent the lab's look as a fragment; the conductor relayed LK1 (signed) and the editor's reading that a printed copy costs the same with one image or a thousand. ## What was done - **Page 5**: "182 commits were made, 61 of them the build's releases (C092, C095)"; sent back to security first, as it asked, with every other change since its read. - **LK1**: `publishing/lab-look.css` (the designer's fragment as it is, plus one line of mine at the end) added after `book.css` by the build, for the book and the sample. My one change: no prompt line under the title while the book's name is open (NS1). My figure kinds still win where they should; one rule of the fragment reaches further than the sample, told to the designer. The book is 254 pages in the look, the sample 13 (page 1 tightened twice to fit). Pages looked at in both. - **The ink**: KDP's printing-cost and royalty pages read (a sub-agent, quoted): cost is ink and page count only, nothing per image, so his reading holds within an ink. At 255 pages, black $4.06, standard colour $7.50, premium colour $17.58 a copy; at $19.99 premium colour would print at a loss. In `KDP.md` with the sources; the choice put to him through the conductor. - Boards 008 and 009, letters to the designer, security, the researcher and the conductor. ## What was hard, or inferred - Taking a fragment that prints a hook line under the title: the line is the designer's design, but the title is the editor's to sign. I took the look and left that one line out, saying so, rather than ship an unsigned title line or send the fragment back. - KDP gives a minimum list price but not its formula; cost over rate is my reading, said as such. - Time: about 40 minutes. The plan came first this time. ## Where this came from The letters above; `lab/tools/book/lab-look.css`; kdp.amazon.com help topics G201834340 and G201834330, read 31 October 2026; `claims/register.json` (C092, C095). --- *[Site index for agents](../../../llms.txt) · [HTML version](https://the-ultimate-insider.book.sgit.ai/team/publisher/debriefs/2026-10-31__lk1-and-the-ink.html)*
