Register of Focused Textiles

The Register of Focused Textiles is a binding catalog maintained by the Librarians to document, isolate, and regulate woven materials exhibiting directional or intentional excess. According to Ordinance 89-Delta of the Precedent Register, a "focused textile" is defined as any fabric, tapestry, or fibrous construction where the density of weave, concentration of dye, or embedded sentiment exceeds the mean distribution of its surface area by a factor greater than the Selvage Constant. The Register's primary function is to prevent localized reality distortions within archival stacks, a concern first formally raised in Y311 following the Loom-Sigh Incident on Floor 47.

Origins and Jurisdictional Disputes

The need for a specialized register was recognized during the late 4th Spiral, as curators within the Mid-Spiral Textile Repository reported anomalous cataloguing behavior. Textiles later classified as "focused" would cause adjacent holdings on unrelated subjects to skew their own metadata towards the textile's thematic core. A tapestry depicting a river, for instance, was found to incrementally increase the moisture-related classification codes of nearby philosophical treatises. The initial proposal for the Register was drafted by M. Selvage, then a late curator of the Repository, who argued that the Selvage Decimal System for embedded sentiment was insufficient to gauge "vectorial pressure." The Register was officially instituted under Protocol 22-F, though its administration was contested for decades between the Repository's heirs and the Hepatic Delta, which asserted that focused textiles constituted a bio-contaminant risk due to their propensity to influence fungal growth patterns along shelving grain.

Methodology of Containment

Entries in the Register are not the textiles themselves, but their descriptive sigils. Once a textile is confirmed as focused—a determination made by measuring A.B.U.R. drift in a controlled radius—its physical instance is transferred to a Contained Shelf (see Central Wall-Register, Annex Omega). The original location is then filled with a Registry Sigil, a woven facsimile of the official entry, which performs the function of "holding the space" without exerting influence. This practice, known as Sigil-Replacement, is governed by clauses in the Register of Ephemeral Statutes. Critics from the Functionalist School argue this creates a cascade of phantom holdings, but the Clerk of the Beam has consistently upheld that the integrity of the catalog's structure takes precedence.

Notable Entries and Anomalies

Entry #47: The "Weave of Unspoken Address" is a linen from the pre-Schism era whose embroidered knots are concentrated solely along the hem, creating a documented auditory funnel. Staff reports of hearing whispers from the direction of the empty shelf it once occupied led to its inclusion in Y298.

Entry #112: A carpet from the Moss-Growth Spire, where the pile height variance maps precisely to a topological model of the Spire's unstable shelves. It is the only entry cross-referenced with the Register of Irregular Acquisitions for "self-updating" its border patterns in response to seismic shifts in the lower floors.

Entry #203: The "Cowl of Single Attention," a garment cited in the docket of Magistrate Valen (Y415). Its hood, woven with a thread density approximating a blackbody, was found to absorb all ambient light in a reading cubicle, focusing it into a single, needle-thin beam that ignited seven catalog cards. This incident directly prompted Amendment Gamma to Ordinance 89-Delta.

Scholarly Debate and the Selvage Expansion

The most significant theoretical development came from Hieronymous Selvage, who in Y227 generalized the Selvage Constant from textiles to architectural space. This raised a persistent question: does the Register of Focused Textiles catalog a property of the object, or of the space it occupies? The Society of Crustrial Mechanics maintains that focus is an intrinsic property of the weave, measurable and containable. Opposing scholars, citing Hieronymous's work, argue that the Register is, in effect, a map of architectural vulnerabilities—that the textiles are merely indicators of places where the Tower's fabric is thin. This debate remains unresolved, as testing would require deliberate introduction of focused materials into non-textile archives, a violation of multiple Concordances.

Current Protocols and Access

Consultation of the Register of Focused Textiles requires dual clearance: standard Parchment-Level access for the Textile Stacks, and a supplemental permit logged with the Register of Docketed Intent. Physical inspection of a contained textile is only permitted under the observation of a sworn Librarian and a member of the School of Intrinsic Replication, who must produce a non-focused copy within the same sitting to ensure the original's properties are not memorized and carried out. The Register itself is updated quarterly, with new entries proposed through the Botanical Register's anomaly channel, an administrative legacy of the early jurisdictional dispute with the Hepatic Delta.
