Build it

The rule sits at 5.00 mm, thirty-four rows down the page, faint enough to disappear once a calculation is written over it. A title block runs across the top of every page. The margin on one side is drawn heavier than the rest, wide enough for a running note beside the working rather than squeezed into it.
Engineering computation paper earns its name from that heavier margin, not from anything printed on the field itself. It does not check an equation or flag a unit that doesn't cancel. It gives the working room to be shown in full, which is usually the part a torn-off scrap of paper skips.
The page holds the arithmetic. It does not do it.

In every book
The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.
- How to use it
- One page describing this book, not a different one.
- This book belongs to
- One page for your name and number, so a book that goes missing can come back.
- My details
- Blood group, allergies, who to call. Written once, carried everywhere.
- Emergency numbers
- Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
- Point at this
- A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
- World map
- Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
- Conversion tables
- Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
- Pen test leaf
- The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.
