Gresham Scale

The Gresham Scale is a formal instrument employed by the Librarians to quantify the potential spread of a contradiction arising between two or more holdings. It provides a standardized assessment of corrosive impact, ranging from a localized textual discrepancy to a systemic threat to concordance integrity.

Development and Rationale

The scale was formally codified by Archivist Gresham in the wake of the Collation Crisis of Floor 217, wherein a series of unmanaged contradictions concerning the Parallax Weave led to three weeks of recursive indexing and the temporary loss of seven spiral staircases. Archivist Gresham's initial treatise, On the Metrical Assessment of Incongruity, argued that not all contradictions are equally dangerous; some are mere scribal errors confined to a single folio, while others, if left unresolved, can propagate through associative cross-references and eventually undermine entire taxonomic branches. The scale was adopted as a mandatory field on Form C-1 (Preliminary Notice of Contradictory Assertion) under Amendment 12 to the Third Concordance.

Scale Degrees and Definitions

The Gresham Scale is a five-degree system, often abbreviated as G-1 through G-5.

G-1 (Localized)

The contradiction is confined to a single edition or a discrete, non-circulating sub-collection. Impact is minimal, with no expected propagation to related holdings. Example: alternate pagination sequences within two copies of the same bestiary.

G-2 (Sectional)

The inconsistency spans multiple volumes within a defined section or floor quadrant, posing a risk to internal coherence but not to the broader classification schema.

G-3 (Floral)

The contradiction implicates core definitions or foundational entries for an entire floor or major conceptual category. Unchecked, it may require a formal Assertion of Primacy and the creation of Negative Volumes to quarantine affected logic chains.

G-4 (Transversal)

The conflict bridges two or more distinct floors or disparate cataloguing systems, threatening to create a Harmonic Void or dissonance in inter-floor referencing. Resolution typically necessitates intervention by a senior Curatorial Board.

G-5 (Systemic)

A catastrophic-level contradiction with the potential to invalidate fundamental concordances or unravel linked metaphysical frameworks. A G-5 rating triggers immediate lockdown protocols and the possible deployment of the Large-Scale Conceptual Press.

Application in Procedure

The filer of a Form C-1 must assign a provisional G-resham rating based on the shelf coordinates of the conflicting sources and a verbatim comparison of the implicated passages. This initial assessment is then reviewed by a Contradiction Clerk, who may adjust the rating after consulting cross-reference indices and assessing the holdings' citation density. A rating of G-3 or higher mandates the opening of a Contradiction Docket, which follows the procedural tones outlined in the Thorne Progression. Notably, the scale measures potential spread, not current severity; a G-5 rating may be assigned to a contradiction currently affecting only a few folios if its logical premises are foundational to a widely used system like the Vex Saturation Scale or the Claudius Scale.

Controversies and Limitations

Scholarly debate persists regarding the scale's subjectivity, particularly in distinguishing between G-3 and G-4 scenarios. The Treatise on Floor-scale Metabolics argues that the scale underestimates the "metabolic velocity" of certain conceptual contradictions, which can spread more rapidly than the static ratings imply. Conversely, adherents of the Kael Practice maintain that the scale is overly granular, and that a simpler tripartite system (Minor, Major, Catastrophic) would suffice for all operational purposes. Furthermore, Amendment 19 to the Fourth Concordance introduced the caveat that contradictions pertaining to the Phantom Thermometry Scale are to be automatically elevated by one degree on the Gresham Scale, due to their observed propensity for thermal dissemination.

Related Instrumentation

While the Gresham Scale assesses the spread of contradiction, other scales measure different qualities of anomalous phenomena. The Turing-Gödel Scale evaluates logical incompleteness, the Hargrove Scale measures ambient Dissonance, and the Vonett Scale for Specificity gauges the precision of undefined terms. A full contradiction report will often cite multiple scales to provide a composite picture of the instability. It is a standing order that any event rated G-5 must also have its resonant saturation measured on the Vex Saturation Scale within one duty cycle.
