Clause D.1

Clause D.1 is a subordinate provision of the D Series Ordinances, appended to the Seventh Concordance, Clause 4 by the Scriptores Minores on the 14th of Frostmoon, Year 881 of the Stack. It governs the disposition of borrowed silence on floors numbered above the Aperture of Unnamed Wells and below the Forty-First Spiral. Its text has remained unamended for eleven recensions, a circumstance the Office of Stationary Dispute attributes to the clause's having been misfiled beneath a treatise on the Inventory of Absent Chairs from Year 402 until its recovery by Clerk Vellin Drass in the winter of Year 892.

Text and Original Attachment

Clause D.1 reads, in the recension certified by the Third Concordance, as follows: "Silence borrowed from a floor whose number is not sequential with its lender shall be returned within three tolls of the Bell of Minor Reconciliation, or compounded at the rate of one dropped syllable per uncatalogued hour." The clause was originally inscribed not on vellum but on a strip of cured thistledown paper, a medium the Librarians reserved for provisions considered temporarily binding. Its attachment to Seventh Concordance, Clause 4 was contested by the Office of Cross-Reference on the grounds that Seventh Concordance, Clause 4 already held the Clause 4.11.γ, and that the insertion created a "nesting irregularity" cited in Annex Alpha as grounds for remeasurement.

"No silence lent across a non-sequential interval shall be deemed returned until the borrower has spoken the floor's name backward to a clerk of the Sub-clause 9.β."

— Clause D.5, Commentary 3

Administration and the Drass Grievance

Clerk Vellin Drass, upon recovering Clause D.1, petitioned the Duration and Review Clause for recognition of precedence over the Clause 7.8, arguing that borrowed silence predated numeric floors. The petition was denied under Clause 1, which the Clause 7 and the Clause 19 both reference for questions of precedence, and which the Clause 19.β further limits to matters of vertical jurisdiction. Drass's subsequent refusal to return silence borrowed from Floor 1180-Ω to Floor 44.8 precipitated the Short Hush of Year 893, during which the Clause 18.7 was briefly suspended by the Seventh Concordance, Annex D, Clause 1.

It is recorded that visitors to the reading galleries may not hum while Clause D.1 is being recited aloud, as the compounded syllable rate then doubles.

Scholarly Disagreement

The Eleventh Recension Board holds that Clause D.1 was implicitly repealed by Clause 14.7.δ, the daughter provision of Clause 14.7, on the reasoning that Clause 14 is the parent clause to Clause 14.7.δ and thus supersedes any D-Series attachment made after Year 800. The Office of Stationary Dispute rejects this, noting that the Seventh Concordance contains Clause 14 alongside Clause 7 and Clause 4, Annex C, and that no concordance may repeal by coexistence alone. The dispute mirrors the impasse reached by Clause 7 regarding Clause 44.8, a route also taken by Clause 19 in laying the philosophical groundwork for Clause IX.2 of Clause IX.

Measurement and Floor Incidence

A survey conducted under Clause 812 established that Clause D.1 applied to 612 non-sequential floor pairs between the Aperture of Unnamed Wells and the Forty-First Spiral as of Year 904. The following table records the three most litigated pairings:

Later Cross-References

Clause D.1 is cited without amendment in the marginalia of Clause 7.03 and is invoked by the Clause 11.γ trustees when contesting the Clause 4.11.γ toll schedules. The Sub-clause 9.β absorbed Clause 9.1.6 in Year 910, and clerks thereafter directed D.1 backward-speech returns to that anomaly rather than to the Office of Cross-Reference. The Librarians have issued no ruling on whether silence borrowed before Year 910 remains owed to the earlier office, a question the Duration and Review Clause defers to the next recension of the Seventh Concordance.
