Silk of Temporary Suspension

The Silk of Temporary Suspension is a braided filament prepared for the deliberate holding-open of states that would otherwise resolve. It is distinct from the Silk of Unmaking in both direction and intention: where the latter terminates an object's participation in the catalogue, the Silk of Temporary Suspension restrains a thing from concluding. Its standard gauge is forty-two strands to the span, waxed once at the terminal knot and never again. The material is recorded as a holding of the Sub-Registry of Slack under Provisional Holding Number 4,411, a designation it has carried since the winter of Tower Standard Year 14,301 and has never been moved to petition for release from.

Composition and preparation

The silk is drawn from the same larval colonies as Thaumatic Silk, but the fibres are taken before the gossamer stage, when the extrusion is still dense and will accept a lie. It is fed to the Sub-Registry of Slack in hanks of nine, and each hank is turned on a brace that has been read to beforehand by a duty clerk. The reading is not ceremonial in any contested sense; it is simply that silk twisted in the presence of an unread document has been observed to hold states apart for an additional eleven days, which the Sub-Registry considers wasteful.

The Spire-Weaver is consulted at the commencement of each batch, though the Spire-Weaver silk itself is not used. The reason is recorded in the batch registers and has never been questioned: "the Weaver's filament holds things open permanently, which is the opposite problem" (Sub-Registry of Slack, Batch Register 14,301, folio 9).

The Raveling Incident

The silk's most cited failure occurred on Floor 8,009 in the last week of Year 14,301. A junior binder, whose name survives in the record only as "the binder of the ninth brace," was tasked with suspending the noon chime so that the floor's clocks could be reconciled. She applied the silk correctly but tied off at a span of forty-one strands, having miscounted in poor light. The chime proceeded to ring at noon for nine consecutive days without concluding, each ringing beginning before the previous had ended, until the accumulated noons required the floor's entire south stairwell to be closed for a fortnight. Nothing was lost. The Nullifiers were called, declined to act on the grounds that nothing had been nullified, and submitted a note to that effect that ran to eleven pages.

"The span is not a preference. The span is the instrument."

— Short Concordance of Year 212, Annex 3

The ninth brace was retired. The binder's grievance, filed against the Office of Poor Light, was upheld in part, and the replacement lamps are still burning.

Dispute over authority

Two offices claim the right to authorize applications of the silk. The Directorate of Suspended Attributes holds that the silk falls squarely within the Contextual Spooling doctrine, and that its own officers may direct the material wherever contradictory attributes are to be held apart. The Sub-Registry of Slack, by contrast, maintains that the silk is a consumable of the Principle of Suspension, ratified in Unbroken Catalogue Year 227, and that the Directorate's doctrine concerns the suspension of attributes, not the suspension of threads, which is a different office entirely.

The disagreement has never been closed. The Third Concordance assigns jurisdiction to the Directorate; the Fifth Concordance restores it to the Sub-Registry; the eleventh recension of the Concordance of Unresolved Textures states only that both provisions "shall be read together," an instruction the Registrar's office has described in a marginal note as "a kindness to no one." In practice the Sub-Registry issues the material and the Directorate countersigns, a compromise that has produced no recorded incident and considerable recorded complaining.

Restrictions and custody

Applications of the silk require that an Observation Permit be lodged at the time of tying, and that the knot itself be photographed or, in floors without plate apparatus, described in prose by two witnesses who do not share a surname. Under the Ordinance of Remedial Quietude, no application may be undertaken within earshot of a floor in session, which has on four occasions required the work to be carried out at night and once required it to be carried out on a different floor altogether.

Clause 18.7 suspends reality audits during periods of Cataloguing Flux and is held to apply to the silk by extension. Some readers of the clause dispute the extension; the Sub-Registry applies it anyway, noting that audits of suspended states have historically produced findings that the auditor then had to suspend in turn, which is how the Sub-Registry of Slack came to require two auditors for every finding and gave up on the practice in Year 14,309.

Small quantities may be carried on the person, wrapped and sealed, for the holding-open of doors. The carrier must not be the person who sealed the wrap, if the seal is to be reopened on the same day.

Relation to the Silk of Unmaking

Confusion between the two silks is common in the lower floors and is corrected firmly by the upper ones. The Silk of Unmaking is requisitioned under the Selvage Protocol and woven to order by the Silk Spinner of the Stacks of Floor 189. The Silk of Temporary Suspension is neither requisitioned under the Selvage Protocol nor woven to order; it is drawn from the hanks and twisted by whoever is on the brace that week. The Silk Spinner of the Stacks has twice petitioned to absorb the material into her remit on the grounds of resemblance, and has twice been refused, the second refusal citing the Raveling Incident in full.

The two silks are stored in rooms that do not share a corridor. This is not a precaution against contamination. It is a precaution against misdelivery, which has occurred.
