The books state distances aboard this ship. The drawing has to produce the
same ones or it is wrong — so it is made to, and the working is shown. These
run again on every build; a compartment moved by a metre fails them.

“The ship is three hundred feet long” Keller's Field, chapter 31
300 stations at one foot. 300 × 0.3048 = 91.44 m, which is hull.loa. The only published length on this sheet and the only one it does not invent.
-
“The run goes from the transfer bay to the after plant, down the middle” Keller's Field, chapter 31
The transfer bay (1-02) ends at station 74; the after plant (4-01) begins at 250; the three run segments 2-01, 3-01 cover 118–250 on band 'centre'. Down the middle, bay to plant.
-
“The run steps up exactly twice, at the second flat and forward of the galley” Keller's Field, chapter 31; Missing, Presumed, chapter 4
Two step annotations only, at stations 118 (second flat begins) and 196 (galley flat begins). Flat z rises 0.0 → 0.9 → 1.8 and never falls. Stated identically in two books two in-world years apart.

“Rourke walks the whole ship in eighteen minutes” Missing, Presumed, chapter 4 — 'it took her eighteen minutes, and it was the last time she did it'
Sanity, not arithmetic: 300 ft of hull, three flats, two steps and a stop at every compartment is a comfortable eighteen minutes. A 300 ft ship that took an hour to walk would fail this sheet.
-
“The missing third of the forward hold's patch is in the galley flat” Missing, Presumed, chapter 4
Compartment 1-03 records the hold shut nine months for a third of a patch; compartment 3-02's note places that third standing on its edge against the galley-flat bulkhead. Two facts, one object, and the sheet says so in both places.
-
“The plant makes a noise at the top of every hour, and about nine seconds later something in the after part of the hull answers it” Missing, Presumed, chapter 4
⛔ NOT A CHECK — A STANDING PROHIBITION. Sarah has never been able to make anybody else hear the second noise and has stopped asking. The entity file rules: DO NOT RESOLVE. No sheet, legend or annotation may explain, locate or name the answering sound. It is recorded here so that a future spec cannot 'tidy' it.

“The handholds are about three inches above where a human hand goes” Keller's Field, chapter 31; Missing, Presumed, chapter 4
Resolved 31 Aug 2026 by author ruling. Keller's Field, chapter 31 and the entity file both read FOUR inches until the Closed Sky adversarial pass corrected Missing, Presumed, chapter 4 to three; Closed Sky is still in drafting, so no figure was immutable and all three were harmonised down to THREE. Grep returns zero occurrences of 'four inches' against this hull.
