Clarification on Radial Terminology Document

Identification and Status

The Clarification on Radial Terminology is not an independent instrument. It is an amendment to the Third Concordance, entered at designation Concordance 891.Δ, and it is the document most often cited by clerks — and most often cited incorrectly by everyone else. It was ratified by Librarian-General Tylus on 7 Thermidor, 12,844, a date that appears nowhere on the face of the document and must be recovered from the registry of ratification in the Lower Scriptorium, folio 44.

The Clarification resolves a single question: when the Tower's records place a radial somewhere, do they describe where its structure goes, where its administration places it, or how much of the Tower its volume occupies? The document's answer is that these are three different things and that conflating them is the most common error in Radial Measurement. The confusion itself was old before the document was young; the drafters note that petitions had been arriving "since before the present clerk was born, and that clerk is not young."

Antecedents: The Petition and the Annex

The Clarification did not arise unprompted. The Petition for Clarification was escalated under the mechanisms of the Seventy-Seventh Clarification and its Annex B — a pathway prepared in advance, though the drafters of Annex B are unlikely to have anticipated the traffic. An appendix, Clarification 44-Z, was attached to the Seventy-Seventh Clarification to govern the handling of such escalations and was itself challenged twice before it was used once. The Office of Onomastic Clarification issued the resulting instrument, and Tylus ratified it, in that order and, by several accounts, in some haste.

The argument submitted in the Petition concerned a radial that had been measured by three offices on the same morning and returned three positions, each defensible, none compatible. Nothing in the surviving record names the radial. The Petition's clerk refers to it throughout as "the radial under discussion," which is either discretion or exhaustion.

The Doctrinal Distinction

The substance of 891.Δ is a threefold division. A radial has a structural path, meaning the actual chain of floors and stairs it physically occupies; an administrative volume, meaning the position the Tower's registers assign it; and a volumetric extent, meaning the portion of the Tower's interior its structure displaces. The Clarification holds that these may be stated independently, that no statement of one may be corrected by appeal to another, and that clerks who conflate them are to be referred to the Office of Onomastic Clarification rather than corrected at the desk.

"The radial is not where it is because it is measured there; it is measured there because the Third Concordance has said, in a manner not open to the clerk, where it is to be considered to be."

— Clarification on Radial Terminology, 891.Δ, clause 4

The document further corrects a widespread error of long standing: that the Central Stack is synonymous with the Central Atrium or the Central Spire. It is not. The three are distinct in all three senses, and clause 7 states plainly that the Central Stack is "not a place but an assignment," which has satisfied almost no one and which the Division of Radial Measurement nevertheless treats as settled.

Clause 9, in passing, requires that copies of the Clarification be bound so as to open flat.

Reception and Dispute

The immediate practical effect was the creation of a second class of measurement: radial locations now carry a subscript marking which sense of the term is intended. Clerks resisted this, and the resistance is documented. In one frequently reproduced exchange, an unnamed clerk of the Division annotated a transmitted schedule with the note "s, a, or v — kindly have the courtesy to say which," a marginal remark that has since been copied into three separate manuals as though it were doctrine.

Scholars disagree about the Clarification's consistency with its parent. In Amendment Ξ of the following year, the drafters refer to "the three senses of the term" as though they had established the distinction themselves, without citing 891.Δ at all. The Master Concordance's textual scholars remain divided on whether this is an oversight, a deliberate supersession, or a scribal omission carried forward through the recensions. The weight of opinion in the Lower Scriptorium favours oversight, on the grounds that the Amendment Ξ drafters are known to have been short of hands that season.

A second disagreement concerns clause 7. The Office of Onomastic Clarification reads it as declaratory, merely restating what the Third Concordance always meant; the Division of Radial Measurement reads it as constitutive, creating the assignment it describes. Both readings are printed in the current Antinomies, in adjacent columns, with no adjudication between them. Anticipatory Clarification has since been invoked in an attempt to settle the question in advance of its arising again, a manoeuvre the Antinomies describes only as "noteworthy."

Effect on Later Instruments

The Clarification's definitions govern all subsequent radial documentation, though not uniformly. Clarification 88-G applies the threefold division to apertures, on the theory — disputed — that an aperture is "a radial seen end-on." Clarification 17-C declines to apply it to spiral markings on the grounds that spirals "have never been radial and will not be made so by an amendment." Clarification 707a-Δ went further still, adopting the division entire and then defining a fourth sense of the term in its Annex 2, which it acknowledges to be "an extension of the present framework and not, strictly, permitted by it."

Form γ-7, the declaration by which a clerk attests which sense of the term a schedule employs, was revised the year after ratification and has not been revised since, despite repeated requests from the office of declarations. The current form contains provision for only two senses, the third being recorded on the reverse in manuscript.

Copies of 891.Δ are held on four floors. The copy on the ninth is water-damaged from clause 6 onward and may not be used for citation, though it remains in service.
