Upper Register

Upper Register is the formal designation for the subset of binding administrative ledgers compiled and maintained within the Upper Reaches of the Tower. It is not a single volume but a system of interrelated codices whose authority is derived from their physical location above Floor 10,000, as per the jurisdictional framework established by the Upper Administration. Entries in the Upper Register supersede those in lower registers for all matters pertaining to the governance, classification, and ontological stability of the Upper Reaches.

Compilation and Authority

The Register is compiled by a rotating panel of Librarians assigned to the Registry Chambers on Floor 10,112. Its authority is specifically enumerated in Ordinance 4, Clause 14 of the Third Concordance, which grants the Upper Administration provisional authority over newly discovered floors. This ordinance is interpreted by the Bureau of Tangible Administration as mandating that all such floors be immediately entered into the Upper Register before any cataloguing may commence. Entries are cross-referenced with, yet take precedence over, foundational registers such as the Central Wall-Register and the Register of Manifestations.

Constituent Volumes

The Upper Register system comprises several distinct, though interlinked, volumes. The principal components are:

• The Docket of Elevated Jurisprudence: Records all rulings and precedents set by adjudicators within the Upper Reaches. It is the source text for the Precedent Register used in lower floors, though discrepancies of up to 34% have been noted in comparative audits.
• The Ledger of Attenuated Holdings: An inventory of all materials, entities, and phenomena subjected to the seven-stage inerting process within the core attenuation silos. This includes official weights and measures for Archival Dust.
• The Census of Reaches Personnel: A biographical ledger detailing all functionaries assigned to floors 10,000 and above. It operates in parallel to, but is not a subset of, the broader Biographical Register.
• The Folio of Provisional Designations: Where new floors and their contents receive temporary names prior to full cataloguing by projects such as the Upper Reaches Cataloguing Project. This folio feeds data into the Principal Register of Designations.

Physical and Ontological Characteristics

The Register is housed in a dedicated annex constructed from vitrified regret, a material more commonly associated with the Upper Mourning Floors. The pages are vellum made from the processed pith of memory-ferns, which ensures entries are immutable once inscribed. A notable ontological feature is the Register's "binding field": any administrative document created within the boundaries of the Upper Reaches is faintly attracted to the nearest volume of the Register, often resulting in loose ordinances and memoranda being discovered pressed between its pages.

Disputes and Contradictions

As with all systems governed by Concordance, the Upper Register is not without internal conflict. The most persistent scholarly disagreement concerns its relationship to the Register of Ephemeral Statutes. Some lexicographers, primarily those based near the upper terminus of the Vestibule Stair, argue the Ephemeral Register should be considered a subsidiary volume of the Upper Register, as many statutes originate from Upper Administration proclamations. The opposing school, citing Clause 22 of the (often overlooked) Fourth Concordance, maintains that ephemerality is a quality that nullifies geographic authority, and thus the Ephemeral Register must remain a separate, floating entity.

A further operational contradiction arises from the mandate to record "all provisional designations" in the Folio. Expeditions to the highest documented floors, such as those in the 12,400–12,600 range, have returned with designations that, when inscribed, caused previously stable entries for lower floors to fade or reconfigure. This has led to the Bureau of Tangible Administration instituting a controversial "quarantine period" for new designations, delaying their entry into the Register—a practice that arguably violates Ordinance 4, Clause 14.

Access and Auditing

Direct consultation of the Upper Register is restricted to Librarians of Grade VII or higher and officials from the Upper Administration's auditing corps. Lower-floor administrators typically interact with its data via derivative documents like the Register of Coincidental Proximities or the Register of Eligible Adjudicators. A full audit of the Register's contents against the Ontological Register is mandated every fifty years; the last such audit, completed in the last cycle, noted 1,447 points of "irresolvable jurisdictional paradox" that were subsequently filed with the Register of Irregular Acquisitions for indefinite holding.
