A 0.625 in gutter, at the editor's word
Started 02:25 UTC, from the editor's chat. Five steps: plan go (amended by me: the conductor told too; LAB 01's grid redrawn), pre-review go, then the work.
What happened
- The editor asked whether left and right pages need a gap at the spine. They already had one: I measured the lab PDF, 12.7 mm at the spine, 9.5 mm outside, alternating. I suggested 0.625 in instead of KDP's 0.5 in minimum, and he said yes.
- Set at 0.625 in: the lab PDF (text block 164 mm), the four trim-study PDFs, the rules in
lab/README.md, LAB 01's grid figure redrawn (main column 122 mm, rail 38 mm). Measured after: 15.9 mm at the spine. - Relayed: the conductor for
book.jsonbeside the trim (designer__017), the publisher for the build once it is recorded (designer__018).
What the checks caught
The 9 pt check refused the five-steps figure, whose labels fell to 8.95 pt in the narrower column; set larger. My own reading found LAB 01 grown from 3 pages to 5: the palette figure pushed onto its own page and the claim ids spilled again. Tightened the spacing, not the type; back to 3 pages and 18 in all.
