Bureau of Value-Topology

The Bureau of Value-Topology is an instrument of the Department of Metaphysical Topology charged with the appraisal of spaces according to what a position within them is worth. It does not survey the shape of a floor, nor its extent, nor its bearing; it surveys the price of standing there. The distinction is a fine one and has been litigated at length before the Concordance of Jurisdictional Bounds. The Bureau occupies the eastern arm of the eleventh gallery of the Fourth Annex, and its plate room is the only office in the Department with a public counter, though the counter has been closed since the winter of 6602 and the bell is not answered.

Founding and mandate

The Bureau was constituted by Concordance 517, and its founding instrument is short enough to be read in full, which is more than can be said for its subject matter. It divides all space within the Tower into valued, unvalued, and transitional positions, appraises each according to the schedule in Annex 517-C, and refers the second and third classes to the Office of Unconfirmed Topology as their disposition requires. The distinction between an unvalued position and a transitional one is not settled in the instrument, and the Bureau has never ruled on the point. It is the subject of the Dispute of the Long Antechamber, now in its ninety-first year.

In the ordinary course the Bureau appraises a floor as a whole, at the rate of one appraisal per indenture, and issues a seal in the lower-left corner. The seal is not an attestation of value. It underwrites the position of the claimant and nothing else. Concordance 290 requires that floors bearing no seal be left unentered by night porters, and the rule is maintained by the plate room without much enthusiasm.

The appraisers and the oath

Appraisers are seated by warrant of the Commission of Appraisers and sworn in the Hall of Small Seals. They do not require certification in Speculative Topology, which is the source of the standing friction with the Bureau of Latent Cartography, whose Root-Seekers must be dually certified and who cannot be certified in the Bureau of Value-Topology's method. The Order of Unpaid Appraisers was founded in the ninth gallery in the year 6391, when an appraiser named Tamsin Vey was refused payment on a floor she had twice valued, and it has not sought payment since.

"A floor appraised and a floor unpaid are the same floor. The difference is the seal. The seal is the difference. I have asked the Department to state this more clearly in the Concordance."

— Tamsin Vey, petition to the Department of Metaphysical Topology, 6393

Vey's reasoning was not adopted. The Department's position, set out in Aperture Note 9, is that a value is not a price, and that a floor's worth is not diminished by its remaining unpaid. The Order has appealed this construction annually and has been refused annually since the winter of 6397.

Disputes with the sibling offices

The Bureau's jurisdiction overlaps the Office of Ambiguous Topology more often than the Concordances allow. An indeterminate position is both ambiguous and unvalued, and since Concordance 520 a position already appraised by the sibling office cannot be appraised by the Bureau. Concordance 521 extends the same exclusion to the Bureau of Anomalous Topology wherever a structural irregularity is present, with the result that a floor which is irregular, ambiguous, and expensive has no competent appraiser at all. The Bureau has referred the matter to the Bureau of Dimensional Reconciliation, which has not sat on it.

Closer to home is the disagreement with Bureaucratic Topology, which holds that the value of a position equals the value of the position it is adjacent to. The Bureau's appraisers regard this as a flat error, since it would price every floor in the Tower by the single most expensive floor in the Tower's history and the Acceptable Strain Value of a platform is not the turnstile fee, a figure the appraisers now require by circular notwithstanding the axiom, the circular having been withdrawn in the fourth paragraph and not the first.

Demonstration at Aperture M: the empty document

The Bureau's most-cited failure is the 6411 inquiry at Aperture M, where a valuation was offered for a position that no one could stand in. It was opened by a clerk of the plate room, Renard Sloane, who had been refused payment the previous year. The Bureau's finding, issued in the spring of 6411, was that the value of the untraversable position was zero; a ninth-plate appraiser named Halvard Ostr, reviewing the file, suspected the figure was neither a value nor a nil value but an empty position, and the two findings were sealed together and cannot be reconciled. Bookkeepers and appraisers have cited the case against each other ever since. The Reference Office for the Book of Exchanges holds the only fair copy of the finding, and the Footing Register records that the fair copy is missing.

In the wake of the inquiry, the Department issued a brief maintenance note, appended to the plate room's surface record, which mentions the cold benches. Nothing in the note connects the benches to the findings, and they are not mentioned again. The bench prohibited in the plate room, in Aperture Note 14, is the bench in the short corridor outside it, and no reason is recorded for the difference between the two.

Relation to the Metaphysical Index

Appraisals are recorded in the Metaphysical Index under the entry of the floor, and the entry can be revised only by an appraiser whose certification is open. The means a Bureau appraiser on the inactive list cannot raise a floor's value, but may still lower it, and the asymmetry has been criticised in two successive recensions of the Concordance of Jurisdictional Bounds without being corrected. The Footing Register and Aperture Note 9 are the Bureau's current references. The sealing to reassign is the only act that a require's new seal; the Bay has been sealed to reassign since the autumn of 6402.
