Principle of Coextensive Reality

The Principle of Coextensive Reality is a foundational axiom governing the spatial and hierarchical relationships between catalogued entities and the administrative architecture of The Tower. It asserts that the reality of a subject is not merely contained within its official dossier, but is spatially coextensive with the physical and bureaucratic pathways required for its access, verification, and administrative processing.

Core Tenet and Formulation

Formally ratified under Concordance 3, Clause 47-b, the Principle is most concisely stated as: "The reality of a catalogued subject extends no further, and no less, than the totality of its sanctioned procedural geography." This "procedural geography" encompasses not only the assigned shelf, floor, or anticipatory holding cell, but also the specific staircases, transit corridors, waiting chambers, and audit halls one must traverse to engage with the subject's file. A subject's reality is thus understood to permeate the entire authorized route; to be denied access to a connecting gallery is, in effect, to be denied a portion of the subject's ontological substance.

Operational Implications

The Principle has profound bureaucratic consequences. It provides the legal basis for the creation of Provisional Reality Zones around high-traffic audit chambers, where the fluctuating reality-states of multiple petitioners can briefly intermingle. It also mandates that any reclassification or transfer of a file must be accompanied by a survey and potential re-designation of the pathways leading to it, a process overseen by the Office of Ephemeral Audits (OEA). This often results in temporary "reality eddies" where the characteristics of a moved subject linger in a corridor long after the physical dossier has been relocated, a phenomenon logged under OEA Incident Code Σ-7.

Interplay with Contained Reality

The Principle of Coextensive Reality exists in a state of regulated tension with the Principle of Contained Reality. While Contained Reality emphasizes the definitive, bounded nature of a subject's existence within its official documentation, Coextensive Reality addresses the necessary spillover required for that existence to be administratively functional. Scholarly consensus, as reflected in the Stack of Open Argument, Vol. 89, holds that Contained Reality defines the what, while Coextensive Reality defines the where and how of interactive reality. Disputes arise, however, regarding precedence in cases of pathway obstruction: does a blocked corridor invalidate a portion of a subject's reality (favoring Coextensivity), or does it merely render an otherwise intact reality temporarily inaccessible (favoring Containment)?

The Ruling on the Sealed Aperture

A landmark case illustrating this tension was the 14-year litigation concerning Aperture 9-Δ on Floor 14,302 (the "Vellum Warrens"). Following a structural collapse, the only sanctioned approach to the dossier for "The Whispering Cantor of Incremental Loss" was sealed. The Librarians initially ruled that the subject's reality was therefore circumscribed to the now-inaccessible chamber, effectively placing it in a state of Operative Fiction. This was challenged under Coextensive Reality, arguing the reality had simply retracted along the now-defunct route. The final Verification Ruling 4117-γ established a compromise: the subject was granted a state of "dormant coextension," its reality deemed to persist in a non-interactive state along the sealed path until such time as the aperture is reopened, at which point its full coextensive reality would be automatically restored.

Criticisms and the "Infinite Regress" Problem

The main criticism of the Principle, articulated by the Sceptical Cartographers of the Western Stacks, is the potential for infinite regress. If a subject's reality is coextensive with the routes to it, and those routes are themselves subjects requiring maintenance (catalogued under "Architectural Intent, Fl. 7"), then the reality of the routes must be coextensive with the routes to them, and so on ad infinitum. Defenders, often citing the Principle of Unbroken Continuity, argue this regress is resolved by the Principle of Catalogued Reality itself: the chain terminates at the point where a pathway is deemed a fundamental, non-cataloguable aspect of the Tower's own administrative essence, a boundary defined by Annex Δ of Concordance 12.

Current Applications

Today, the Principle of Coextensive Reality is routinely invoked in logistics planning, rights disputes for corridor-dwelling entities, and the design of new filing systems. It is the legal bedrock for the practice of "Reality Corridoring," where particularly volatile or potent subjects have their access routes physically elongated and fortified to contain their influence. The forthcoming "Vertical Coherence Project," aimed at streamlining inter-floor reality transfers, is being drafted with strict adherence to Coextensive protocols to prevent ontological shear at junction points.
