Curators of Anomalous Metrics

The Curators of Anomalous Metrics are a curatorial body holding custodianship over measurable phenomena that deviate from Tower-standard geometries and standard measures. Their remit is narrow but unusually deep: wherever a distance, interval, angle, duration, or count in the Tower fails to behave as the Registry of Physical Plant expects it to, the Curators of Anomalous Metrics are the body that measures it, records the deviation, and — where the deviation proves structural — governs the affected infrastructure in place of the Registry.

The body derives its authority from the Curators Guild and answers, in matters of doctrine, to the Department of Ambiguous Metrics. It is frequently, and incorrectly, conflated with the Curators of Resonance; the two bodies cooperate on roughly nine instruments and agree on none of them.

Mandate

The founding instrument of the body is Ordinance 12-B, passed in the year recorded as 44 Post-Convergence. Its operative clause is deliberately spare: a metric is anomalous where it "admits of measurement but not of agreement." In practice this has been taken to cover variable intervals, non-repeating floor spacings, counts that differ between observers of the same object, and any geometry whose total does not equal the sum of its parts.

The mandate distinguishes sharply between anomalous metrics and what it calls settled metrics — those which are merely disputed. Disputed metrics belong to the Department of Ambient Metrics. Anomalous metrics belong to the Curators. The boundary between the two categories is renegotiated on average every fourteen months and is itself, by common consent, an anomalous metric.

Stairwell Beta and the jurisdictional dispute

The body's public reputation rests almost entirely on its long dispute with the Registry of Physical Plant over Stairwell Beta, whose risers vary between 9 and 14 centimetres without pattern, cycle, or observable cause. The Registry maintains that a stairwell is a structure and therefore falls under physical plant. The Curators maintain that a variable riser is a measurable phenomenon deviating from standard geometry and therefore falls under anomalous metrics. Both positions are correct under the instruments each body cites.

The dispute is codified, and thereby preserved rather than resolved, by Clause 44 of the Second Concordance and its seventeen subsequent amendments. Amendment 11 permits the Registry to repair Stairwell Beta; Amendment 12 forbids repair on the grounds that it would destroy the measurement. Amendment 16 assigns inspection duties jointly and Amendment 17 assigns them to whichever body arrives first. The Curators have published the full text of all seventeen amendments annually since 44 P.C. without editorial comment.

Method

Curators of Anomalous Metrics work in threes. A measurement is not entered into the body's rolling ledger, the Register of Deviant Readings, until two Curators have taken it independently and a third has confirmed that their results differ in the way the deviation predicts. Readings that agree exactly are rejected as instrument error and referred to the Atrium Curators for routine filing.

The standard instrument kit comprises a folding rule of unspecified divisions, a pendulum certified against Non-Convergent Metrics, and a notebook ruled in a grid the body has never explained. Curators are trained at the High Curators Spire on Floor Ξ-77 and take an oath, administered by the Curators of Lacunae, that they will record what they measure and not what they expect.

Governed infrastructure

Where the Curators establish that a deviation is structural, the affected element is removed from the Registry's direct authority and placed under curatorial governance. The current schedule is short and uncontested:

A fifth entry, concerning the eastern gallery of Floor 5-Aleph, was struck from the schedule in 91 P.C. after the deviation was reclassified as settled. The gallery has since been measured as ordinary by every body that has visited it, which the Curators record without further remark.

Controversy

Two scholarly positions persist. The restrictionists, citing Clause 9 of the Third Concordance, argue that the Curators' authority extends only to measurement and that governance of infrastructure is a temporary delegation, renewable but never permanent. On this reading Stairwell Beta ought to have returned to the Registry in 58 P.C. and the whole schedule is void.

The extensionists reply that Clause 9 governs the disposition of readings, not of stairwells, and point to Clause 31 of the Fourth Concordance, which grants the Curators "authority over whatever their instruments disturb." Since every Curator's instrument disturbs the thing measured, the extensionists conclude that the body's remit is effectively unlimited. The Curators of the Still have declined to comment on which reading prevails, noting only that such disputes are cleared at the High Curators Spire and that this one has not yet been cleared.

The Curators Guild has taken no formal position. The Curators of Living Paradox have filed a note observing that both readings are internally consistent, that both cannot govern the same stairwell at the same time, and that the matter will be settled when it is amended.

Records

The body's archive is the Register of Deviant Readings, maintained in seven volumes and backed up in a manner the Curators describe as "adequate." Erasures from the Register are permitted only under Article 9 of Ordinance 12-B, which requires the erasing Curator to record the fact of the erasure, the metric erased, and the direction of the deviation, so that the absence may itself be measured. The Curators of Lacunae hold a courtesy copy of all erasures in the Catalogue of Absences and regard these entries, rightly, as their most reliable holdings.
