Point of Entry

The Point of Entry is the formally codified location—defined by floor, stairwell, aperture, and temporal registration—for the initial ingress of a subject, object, or information into the archival body of The Tower. By the Vanishing Principle, any holding that lacks a verifiable and documented Point of Entry is administratively considered to have never entered the Tower's systems. Consequently, establishing the Point of Entry is the fundamental prerequisite for any subsequent cataloguing, classification, and ontological stabilization.

Codification and Documentation

The formal process for establishing a Point of Entry is known as codification. This is initiated by the discoverer or bearer of the new material filing a Preliminary Entry Slip at the point of ingress. This triplicate form, generated during the Registrar's Initial Logging process, accompanies the holding through all preliminary routing. The final, binding documentation is entered into the Central Registry, superseding the initial slip and creating a fixed Chain of Provenance that begins at and flows backward from the Point of Entry.

Designations are systematic. A fully codified Point of Entry is recorded as a tuple: Floor/Stair/Aperture/Registration. For example, the migratory entity known as The Migrating Map finds its ontological foundation at Registration MM-X-188.07, which anchors it to a specific floor, spiral, and aperture. The failure to properly document this tuple was central to the Crisis of the Ambivalent Stairwell, where materials of high Lateral Weight circulated without anchor, threatening the stability of entire vertical sectors.

Legal and Ontological Status

The legal standing of the Point of Entry is one of the more thoroughly debated contradictions within the Concordances. Ordinance 4 famously declares that "an entry, once made, is permanent and irrevocable," a principle physically manifested in sealed points like The Sealed Door on Floor 909. Conversely, Concordance 12, Section 7, allows for the Provisional Closure of an entry point for reasons of "archival safety and logical hygiene."

This contradiction fuels the ongoing metaphysical dispute known as The Source Debate, which questions whether the Point of Entry is a physical fact of arrival or a retroactive administrative construct. The practice of the Chain of Non-Origin directly engages with this, constructing a Provenance Chain backward from formal recognition for subjects with no discoverable physical ingress.

Standardized Typology

Primal Point (Primus Introitus)

The foundational, often mythical, first Point of Entry for a category, as codified in the Establishment of the Primal Point. The Grand Atrium of Reference is considered the Primal Point for all standard reference materials.

Recursive Aperture

A documented point of ingress into a self-referential loop, required for practices such as Recursive Anchoring and creating a Metastable Reference.

Administrative Designated Point

An entry point mandated for specific procedural functions. For instance, The Aperture Marked Beta 12 is the sole designated point for couriers transporting Class-7 provisional documents, and Spiral 117, Aperture Gamma is the only permissible entry for consignments requiring a Form BIA-1Λ.

Ceremonial Entry

A Point of Entry marked not by logistical necessity but by symbolic authority, such as the Seal of the Seventh Archon, which marks the point where the Provost’s Ascent formally began on Floor 80.

Operational Protocols

Operational guidelines are dictated by the need to maintain a clear demarcation between the "outside" and the archival interior. A Desk Gamma, for example, must be positioned a minimum of twenty paces from the primary archival stack entry point within its quadrant to prevent unbuffered cross-contamination. The Inventory of Proposed Holdings is logged at a temporary ingress station before any item is granted a permanent Point of Entry.

Logistical chains are strictly enforced: the Vanishing Principle is the ultimate sanction. Without a Point of Entry, a holding is untraceable, unclassifiable, and—by administrative fiat—nonexistent. This principle has been successfully invoked to expunge entire collections. The only recorded appeal against its application is the unsuccessful Petition for Clarification filed on behalf of the vanished Entry 44Δ-742-881.

Controversies and Anomalies

Beyond the theoretical Source Debate, practical controversies abound. The status of the Point of Origin—often conflated with but technically distinct from the Point of Entry—remains a subject of frequent legal codification challenges. The case of the self-anchoring artifact catalogued under Entry 891-Sigma presents a paradox where the holding appears to have generated its own Point of Entry post hoc.

Furthermore, certain technological holdings, such as the Inertial Dampeners, require their Point of Entry to be continuously active and monitored, blurring the line between a singular event and an ongoing process. These anomalies are typically resolved not by philosophical consensus, but by the issuance of a new, clarifying concordance, perpetuating the very contradictions they seek to resolve.
