Central Wall-Register

Central Wall-Register (officially the Compendium of Certified Partitions and Associated Jurisdictions) is a master listing of all walls, partitions, and structural dividers whose dimensional integrity has been ratified by the Register of Nominal Extents and assigned administrative authority. Maintained by the Office of the Grand Registrar, it serves as the definitive arbiter of spatial claims, bureaucratic responsibility, and archival taxonomy pertaining to any recognized barrier within The Tower.

Function and Scope

The Central Wall-Register’s primary function is twofold: it certifies a wall’s existence as a discrete administrative entity, and it allocates custodial mandates to relevant departments. A wall achieves "registered" status following a formal application process to the Register of Nominal Extents, a survey by the Bureau of Dimensional Reconciliation, and the successful resolution of any border disputes recorded in the Register of Docketed Intent. Upon registration, the wall is assigned a unique identifier, such as Wall Sigma9, and its entry is linked to the custodial department’s quarterly compliance reports. The Register governs everything from structural maintenance schedules (e.g., the sonic-dampening basalt of Wall Sigma9) to the legal status of apertures (like those governed from the Central Aperture hub) and the archival classification of materials shelved against it.

Physical Format and Location

The Register is not a single volume but a distributed system of interlinked ledgers and chits spanning multiple floors. The master index resides in a dedicated annex adjacent to the Grand Registrar's office on the central administrative level, with duplicate sub-registers housed in relevant precincts. For instance, the section pertaining to the East Unbound Stacks, which includes the entry for Wall Σ-9, is maintained within Annex B of Floor 112, where it shares a structural wall with the central bureau of the Department of Matriculation. Updates are disseminated via the brass message tubes of the Central Aperture network, though scholars note a 72-hour standard delay for updates to propagate to peripheral sub-registers.

Jurisdictional Authority and Disputes

A wall’s registration carries significant bureaucratic weight. It determines which department authorizes repairs (governed by Concordance 3.14.7), which office processes noise complaints (referencing the Central Vibration Register on Floor 47), and which guild is responsible for the installation of shelving or fixtures. Disputes most commonly arise when a single wall serves as the border for multiple departments. The contested status of the shared wall in Floor 112, Annex B has generated over 200 petitions, now archived in the Index of Unresolved Imperatives. Resolution typically requires cross-referencing with the Precedent Register and the Master Amendment Log, though outcomes often establish new, equally contradictory precedents.

Notable Entries and Anomalies

The Register’s most cited entry is for Wall Sigma9, notable for its certified thickness of 4.82 meters and its role as the permanent partition between the East Unbound Stacks and the Lower Stacks. Other significant entries include the Wall of Lapsed Directives (a repository for obsolete ordinances) and the disputed western bulwark of Spire 3. Anomalies consist of walls that appear in the Register but lack physical corroboration in subsequent surveys; these are classified as “Theoretical Partitions” and their custodial mandates are filed with the Register of Ephemeral Statutes.

Scholarly Controversy

A persistent debate concerns whether the Central Wall-Register catalogues walls that divide space, or whether the act of registration itself creates the administrative division. Proponents of the "Constitutive Theory," citing amendments logged in The Master Amendment Log between 7,402-7,405 A.T. (After Tower), argue that a wall’s jurisdictional authority is ontologically prior to its physical substance. This is contested by the “Substantivist School,” which points to the material specifications in entries like Wall Sigma9 as proof of physical primacy. The controversy is considered unresolved, with relevant case law indexed under “Dimensional Precedence” in the Index of Superseded Clauses (See: Vol. CXII, pp. 455-457).
