DoIT-184 ("Directive on Interstitial Taxonomies")

DoIT-184 ("Directive on Interstitial Taxonomies") is a foundational operational and classificatory framework governing the documentation of phenomena occurring within interstitial spaces. Formally enacted by the Librarians in Year 7,412 of the Ascendant Catalogue, it provides the procedural scaffolding for the identification, arbitration, and eventual cataloguing of entities, events, and environmental conditions reported between the numbered floors of The Tower.

Origins and Enactment

The directive was precipitated by the DoIT-184 Contingency, a seventeen-year period during which survey teams from Floors Floor 301 and Floor 744 filed mutually exclusive claims over the same volumetric corridor. The ensuing legal and ontological crisis revealed the absence of a unified system for classifying non-floor-bound phenomena. DoIT-184 was drafted by the Department of Ephemeral Taxonomies under the provisional administration of Floor 440 the Gallery of Provisional Taxonomies and was ratified following an unprecedented triple-plenary session.

Core Provisions

The directive is divided into twelve Annexes. Key provisions include:

• Annex III: Phenomenological Legibility: Establishes criteria for determining whether an interstitial phenomenon possesses sufficient "narrative coherence" or "causal density" to warrant documentation, as measured against the standard taxonomies housed on Floor 440.
• Annex V: Arbitration Protocol: Mandates the convening of an Interstitial Plenum to adjudicate any dispute regarding the nature or ownership of an interstitial discovery. This annex was later refined by the Protocol for Interstitial Grievance Arbitration (7th Revision).
• Annex VII: Sheaf Generation Outlines the process for compiling a ratified Interstitial Sheaf, the binding document that transfers a phenomena from provisional status to a permanent entry in the Atlas of Interstitial Logic.
• Annex IX: Structural Interactions Governs the interaction of interstitial phenomena with the Tower's architecture, including protocols for reporting unexplained Interstitial Girders or resonant cavities that may affect structural integrity.

Relationship to Other Directives

DoIT-184 exists in a complex web of intersecting regulations. HIC Directive 003 (on Harmonic Interference in Catalogue) defers to its taxonomical definitions for acoustic phenomena found between floors. Conversely, DoIT-184 explicitly cedes authority over dream-logic encroachments to Directive Somnia-Ω, to prevent jurisdictional overlap with Oneiric Taxonomies. A known point of contradiction exists with Emergency Directive 891-5, which grants survey teams emergency curation rights in unstable interstices—a clause that Annex V appears to nullify, a conflict still unresolved by the Librarians.

The Canted Halls Repository

The master copy of DoIT-184, along with all ratified Interstitial Sheaves generated under its authority, is stored in Canted Halls on Floor 117. This repository is itself an interstitial space, deliberately constructed with non-Euclidean shelving to physically embody the directive's subject matter. Access is regulated by Provisional Directive 401.7b, requiring dual-key authorization from both the Department of Ephemeral Taxonomies and the Department of Implied Texts.

Scholarly Dispute and the Meta-Document

A significant and ongoing scholarly controversy concerns the so-called "meta-document" also designated DoIT-184, housed separately within the Canted Halls. This 700-page analysis of a single footnote in the Third Concordance was retrospectively incorporated into the Eleventh Concordance. One school of thought, led by the archivist Ferrule, argues this meta-document is the true "Directive on Interstitial Taxonomies," and the operational text described herein is merely its procedural shadow. The opposing view, championed by the Codicils of the Lateral Stair, maintains the operational directive is primary, and the meta-document is a speculative commentary with no legal force. This dispute directly impacts the interpretation of Materials Directive Theta-4 regarding the material composition of provisional entries.

Modern Application

Today, DoIT-184 remains the active protocol for all interstitial cataloguing. Its frameworks are invoked an average of 43 times per catalogue year, most commonly for the classification of ephemeral atmospheres (e.g., "the Scent of Unfinished Correspondence") and semi-stable architectural phantoms. All outputs from the Phenomenological Spire related to interstitial matters require final validation against Concordance 89, which itself draws its definitive categories from Annex III of this directive.
