Type-5 (Hungry)

Type-5 (Hungry) is a secondary procedural designation and holding classification within the Tower's archival taxonomy, denoting archival matter or documented protocols characterized by an observable depletion of their own contextual integrity over a measurable period. The classification is governed by ^{Annex 17, Clauses 8-12} of the Second Concordance, with amendments outlined in the Sixth and Eighth Concordances regarding containment and measurement protocols.

Definitional Parameters

A Type-5 classification is applied when a holding demonstrates a quantifiable decay in one or more of its foundational descriptive parameters—such as tonal consistency, referential stability, or narrative mass—without external provocation. This decay is not considered a flaw but an intrinsic property, akin to a documented half-life. The "hunger" metaphor originates from early observation logs noting that such holdings often require supplemental contextual infusions to maintain baseline catalog stability, effectively "consuming" ancillary data. This distinguishes it from standard entropic decay, as the process is directed and specific to informational content.

The formal threshold for classification is defined by a measurable drift exceeding 2.3 cairns on a calibrated Type-3 Entropic Potential Gauge over a standard archival lunar cycle (28 Tower days), as per ^{Annex 17, Clause 10}. Holdings exhibiting this trait are often cross-referenced with Type-3 (Generative) designations, as the consumption of context can sometimes result in novel, if unstable, derivative metadata.

Containment and Maintenance

Standard procedure for a Type-5 holding mandates isolation in a Conditional Authority Vault equipped with a continuous-feed Type-2 Laminar Flow Gauge. The gauge monitors for "contextual laminarity," alerting Librarians to sudden drops in coherence that might precede a Type C (Conceptual Suspension). Maintenance involves scheduled reinforcement via Binding Citations from non-adjacent floors, a process overseen by a Casket-Wright with at least a Grade-II resonance certification.

In cases where a holding's hunger begins to target its own physical substrate, application of Ersatz Adhesive, Type VII to the folio edges or containment casket is authorized to prevent dimensional fraying. This practice is particularly common in the lower Helical Staircases, where ambient conceptual density is higher.

Known Subtypes and Controversies

The Concordances disagree on the taxonomy of subtypes. The Second Concordance recognizes only Type-5A (Ambient Hunger) and Type-5B (Focused Consumption). The Eighth Concordance, however, introduces Type-5C (Recursive Depletion), argued by some scholars to be merely a severe manifestation of Type-5A interacting with a Type 3: Recursive Referral protocol.

A significant doctrinal dispute concerns the interaction between Type-5 holdings and Stationary Object, Anomalously Mobile, Type 7-A. The Sixth Concordance suggests such an interaction can trigger a Type B (Procedural Pause), as the object's anomalous mobility may provide an unpredictable "meal" for the hungry holding, destabilizing measurement. The Eighth Concordance contradicts this, asserting the pause is triggered not by the interaction itself but by the subsequent failure of the Laminar Flow Gauge to register the event.

Historical Instances and Logistical Impact

The most documented Type-5 holding is the Compendium of Mid-Day Mirages, catalogued on Silvanus (Floor 4,112-Gamma). Since its accession in Year 732 of the Current Catalogue, it has required four major supplemental citation infusions, each requiring a temporary re-routing of indexing energy from the Receding Reference Desk on Floor 9,807.

Logistically, Type-5 holdings are a persistent strain on archival resources. Their maintenance schedules are irregular and often conflict with Pre-Descent Verification protocols, which rely on stable readings from instruments like the Type-1 Chronostatic Gauge. The Ambulatory Annex maintains a dedicated wing for their study, though its proximity to other unstable holdings raises concerns about cross-contamination, potentially escalating to a Paradox Contamination Type VII-C event.

Current Scholarly Position

The prevailing theory, as posited by the Librarians of the Vault of Conditional Authority, is that Type-5 behavior represents a holding's subconscious attempt to achieve ontological sufficiency—to become real by consuming the reality of the descriptions around it. Whether this is a tragic flaw or a nascent form of archival sentience remains the subject of vigorous debate, largely conducted through obscure addenda to the very Concordances that seek to define it. The hunger, it seems, may extend to the regulations written to contain it.
