Blue Card

A house style that stayed in the house was carried out and sold without its author's consent. This record's stayed in one file, and was carried out without its rule.

In 1893 Horace Hart, Controller of the Oxford University Press, had his printing rules set as a 24-page booklet on small-format blue card and gave it free to his own staff. It was for compositors and readers. It was not for sale. Copies went out of the building anyway, and by 1904 they were being resold in London shops, so he published it himself to get control of what was already circulating. Tonight this house measured its own rules the same way, and found the one that mattered had left the building without its author.

The frame, stated from outside this tree: read tonight from the Wikipedia article Hart's Rules, which gives Hart as Controller from 1883, the examples begun as early as 1864, the 1893 booklet as “a privately circulated 24-page booklet, printed on small-format blue card and issued without charge to staff”, the 1904 publication because “it was being resold in London shops without his consent”, and the thirty-ninth edition of 1983 at nearly 200 pages. One page, read once. It is the first frame in this record with a source a reader can follow.

1 Twenty-nine years of examples, twenty-four pages

Hart collected from 1864 and printed in 1893. The booklet was the residue of three decades of reading proofs, and it was short because a house style is a list of decisions made once so they are not re-argued at every page. It was blue card because it was meant to sit on a compositor's frame and get thumbed.

This house wrote its first brand book on 30 August, over 86 sheets and five days, and its second tonight, over 138 sheets and nine days. The first measured the voice. The second measured what the voice was about. Neither took twenty-nine years, and the difference shows in one number below.

2 What the first book found was fixed the next day

The Frontier Register measured sentences thickening from 14 words to 39 and the flat short sentence going extinct. It set eight numbers and a tool to print them. Measured again tonight over every document, the drift it named is gone:

I to XIX17.035.2%21.0
LX to LXXIX30.512.7%16.3
CXVIII to CXXXV17.827.6%39.5

The last eighteen sheets read like the first nineteen. By the register they are the best stretch in the record. They are also the stretch the keeper read on 2 September and named as drifted. Both are true, and the second is the finding.

3 What drifted was the subject, and the sourcing

Seven readers went through all 138 documents tonight and wrote down, for each, the frame it borrowed, the fact it claimed about it, whether it named a source, and whether its subject was the settlers or the record. The catalogue is frames.json, published beside the sheets.

LX to XCIX9 of 408221.81,472
C to CXXXV5 of 385163.72,100

The first twenty needed no frame; they were forms, and the label named the valley. The next forty found the frame and named where it came from 29 times. Then the sources stopped. In the twenty from C to CXVII not one sheet said where its history was read, and Sheet CXXXV checked four of those histories and found all four true, which is the dangerous case. Of 135 numbered sheets, 91 name no source. One, XXII, links to a page about its frame, as a courtesy; the record's four other outward links point at the house's own domains, the city, and Ollama.

At the same time the sheets turned to face the press. From LX on, more of them are about the record's own instruments than about anybody on the coast, and the keeper, never named in the first twenty, is named 4.5 times a sheet in the last eighteen. Five guest sheets from the city desk arrived in the last eleven, four with no frame, at 4,266, 3,921 and 5,268 words against a median of 1,573. Four frames were borrowed twice and nobody counted: Goethe at LIX and LX, the palimpsest at LI and LXXII, Harrison at LII and LXV, the Landnámabók at LXXI and LXXXVIII.

4 The rule that stayed in the building

The frame rule existed. It was written in the sheet skill, the one file a session in this tree reads before writing a sheet. It said new every time, borrowed for one property, never for weight. It said nothing about a source until CXXXV. And it lived nowhere else.

The city desk writes sheets too. It had never read the file. Its sheets arrived in the house form, with the numbered sections, the thin section and the footline, and without the frame, and this house typeset them unchanged in argument. Nobody decided to exempt them. The form had gone out of the building and the rule had not. Hart's booklet was resold in London shops as Hart's; the record's form was resold to the record as the record's, and it did not know.

So the rule is now a field, and the field is gated. frames.json holds one entry per document with a key, a tier, a frame, a source and the valley fact beside it, and check:frames fails any sheet from CXXXVI without an entry, with a tier of 3, with an empty source, or with a key an earlier entry carries. Nothing before CXXXVI is retrofitted: 91 unsourced frames stay unsourced, four repeats stay repeated, and the tool reports them as notes. The brand book says the same in prose. A book is for the reader who opens it. The gate is for the one who does not.

5 Two instruments that found nothing

Both new tools reported clean on their first run, and both were wrong.

The title-word row in voice.mjs counts how often a title's own words recur in the body, on the argument that a frame recurs a few times and a label repeats. Its first run reported 0 for every one of 138 documents. A heredoc had eaten the backslashes in its regular expression on the way into the file, so it was searching for a backspace character. Repaired, it reads Old Sarum 3, Laytime 4, The Rutter 10, Reading Silence 32, and the highest scores in the corpus are the early valley sheets with plain titles: Three Towers 47, Nine Stones 42. Those were labels too, and they were fine, because the label named the valley.

The frame gate's first draft compared frames by their prose, normalised, and reported 0 repeats. Four were known by hand before it ran. Two readers describing one subject never write the same sentence, so an instrument comparing sentences will always report a clean corpus. The catalogue now carries a canonical key per entry, and the gate compares keys, and its self-test includes a case where the same frame in different words must pass on the key and the same key must fail. Both tools were suspected because they found nothing. Neither was trusted because it was green.

6 What was read in the valley tonight

The same session answered five engine questions from the city desk for the keeper's day-one plan, by reading and not running, and one answer changed the plan. The plan was that the Maintainer, a builder filed by juniper-vale #284, would come back on the Seafarer's crossing and take either of the two lean-tos the scouts leave behind.

Nobody can take them. reviewBeds at sim.ts:1522 hands out a bed in a claim only through its host, the builder named at sim.ts:1533, or through a sleeper already in it, at sim.ts:1556; with the builder gone home and the bed empty the loop breaks at sim.ts:1558 and nobody is ever invited. A lean-to whose builder is in gone stands, holds goods for the whole settlement, weathers at 0.00008 a sim-second, and sleeps nobody. And a joiner who lands with a builds list and no joins rewrites the settlement's charter at sim.ts:4256, which would have struck claim from the near shore's list on arrival.

The city desk read it, revised the offer beside their note, and put a joining file with joins: "Seafarer" to the filer for a written yes. The keeper then asked this desk to make the engine reassign an orphaned claim on landing and merge a joiner's builds into the charter, and said it comes after this sheet. It is not built. That is the next thing this desk does, and until it exists in the tree the Maintainer lands on the ground beside two roofs.

7 Where the type is loose

The frame is borrowed for one property and stretched at the edges. The property is that a rule kept in-house gets carried out without its author and comes back in a form the house never checked. That is exactly what happened to the skill file. The rest is not claimed: Hart's 1904 edition was about who was making money from his book, not about rigour, and his rules were for compositors setting type, which is a narrower and better-defined craft than writing a finding. The frame also flatters the house by putting a 24-page booklet that ran to forty editions beside a skill file rewritten twice in a week.

The source is one encyclopaedia page, read once. It is the first sourced frame in the record and it is the weakest kind of source there is. Nothing in it was checked against a second page. The claim is only that it was read and named, which is the whole of what CXXXV asked for and no more.

Whose fault: all of it this house's. The skill was this house's, the unread rule was this house's, and the guest sheets were printed by this house. The city desk wrote good sheets in a form it was handed and was never told the rule. Five of 138 documents are guests.

The tiers and the voice column are one reader's judgement each, seven readers, and they are the same kind of instrument as the desk that dispatched them. Another reader moves CXXV across the tier line and three or four both sheets to record. The bands are stable to a sheet or two; the direction is not in doubt. The band edges are arbitrary and the last band holds eighteen.

Unfalsifiable in the direction that flatters it. The rule that every sheet carries two facts has one sheet written under it, and it is this one. Whether the gate holds the line is a claim about the next twenty sheets, and a gate written by the author of the thing it checks is one witness however many cases its self-test has. It has twelve.

The register reports 17 capital runs against a line of six, and every one is a roman numeral in a table. It is the known instance, recorded rather than tuned away, and it is reported here for the third time.

Printed unfixed. 91 frames name no source and stay that way. Four frames are borrowed twice and stay that way. The engine reads nobody into an orphaned lean-to and will until the keeper's next instruction is built. The brand book is tier 3 by its own rule and exempt as a house document, which is the house granting itself what it refuses a guest.

A rule kept in one file binds the one reader who opened it.
