Voss-Septus

Voss-Septus is the seventh and least attested of the Voss designations, a grade of material coherence applied to substances whose measured fineness cannot be reproduced on demand. It was not established by Auditor Voss in the original Voss Recension — which provided for four grades, as recorded in the Recension's Schedule A — nor by the marginal addition that produced Voss-Quintus. It emerged later, by a route the Office of Material Coherence has never satisfactorily documented, and its standing relative to the other six designations remains the subject of an open file in the Office's registry, opened in the eleventh year of the current recension cycle and still open.

Origin in the Somnic Record

The designation first appears in the catalogue entry for Somnic Chlorite, the mineral first indexed by Junior Indexer Elara Voss. In her original field notes, dated to the third quarter of the survey year and preserved in the Office's annex, the Indexer recorded a chlorite sample that read as Voss-Quartus on first assay, as Voss-Secundus on a second assay conducted eleven days later, and as Voss-Primus on a third. Rather than assign a grade, she wrote a single line across the bottom of the page: "Fineness seven; not a fineness but a habit of the stone." The phrase "fineness seven" is the earliest known use of the term, and the Indexer never elaborated on it in any surviving paper.

When the Voss family's hereditary archival branch prepared the mineral for full cataloguing, the annotation could not be discarded and could not be reconciled with Schedule A. A seventh grade was entered into the margin of the working register in a hand that has never been identified. The Office has twice attempted to establish the writer's identity through comparison with the signatures held in the Recension's compilation folios. Both attempts failed; the comparison was abandoned in the ninth year, and the folio remains unassigned.

Adoption and the Fineness Schedules

The grade entered ordinary use through the Voss Recension of the Fineness Schedules only after the journal M. Voss published a short assessment by Elara Voss — then serving as countersignatory for The Voss Series under the Secundus designation — arguing that a substance which assays differently on each occasion is not thereby indeterminate but is determinate in a manner the four-grade schedule does not express. Her argument rested on the triangulation technique pioneered by Kaelen Voss, applied to sonic beacon returns from sealed assay chambers. The assessment was accepted for the Series and, two cycles later, for the Schedules.

The Office's own guidance on the grade is deliberately narrow:

"A material designated Voss-Septus shall not be described as of any fineness. It shall be described as of fineness seven, which is a description of its behaviour and not of its substance. Assessors are reminded that the two are not the same and that the distinction has been upheld."

— Ordinance 702.4, Annex 7, clause 3

The distinction has indeed been upheld. In a disputed assessment concerning a shipment of chlorite held on the Seventy-Second Floor, the Custodial Guild argued that a Voss-Septus designation was void for uncertainty. The adjudicating body found for the Office, holding that fineness seven is certain precisely because it promises nothing. The Guild has not appealed, though its standing objection is reprinted in each annual return.

Scholarly disagreement

Whether Voss-Septus is a grade at all is contested. The Concordant Law commentary treats the designations as an ordered series and reads the septon as its head, on the reasoning that a substance whose fineness cannot be fixed is finer than one whose fineness can. The Third Concordance, Annex 2, takes the opposite position and places the septon beneath the four established grades, on the reasoning that a grade which cannot be reproduced is a grade which cannot be relied upon. The two documents are of comparable antiquity and neither has been withdrawn.

A third view, advanced in a private recension held by the Office and never published, proposes that the septon is not a position in the series at all but a note attached to the series, and that the dispute is therefore about the numbering of a note. The Office has declined to rule on this view, noting only that the private recension is private.

Practice

Assessors apply the septon sparingly. Current practice permits its use only where three assays, conducted at intervals of not less than seven days, return three different established grades; the intervals are recorded and the record sealed. The resulting entries are among the most frequently queried in the catalogue, as readers reasonably expect a grade to settle a question and the septon settles none. A visiting rule, in force since the grade's adoption, requires that any reader consulting a Voss-Septus entry sign the query register twice — once on entry and once on departure — so that the interval may be measured.

The grade's present standing is that of a designation everyone cites and few can define. The Office keeps the original annotated register in a locked cabinet on the Seventy-Second Floor. It is consulted, on average, four times a cycle.
