Clause 8, Annex 9

Clause 8, Annex 9 is a procedural provision of the Ninth Concordance governing the recension of floor inventories prior to their deposit in the Archive of Second Copies. It is chiefly notable for the so-called Silence Rule — the requirement that an inventory be entered twice, once by the compiling clerk and once by a clerk who has not read the first entry — and for the protracted dispute over whether the rule was superseded by Clause 4 of Annex 7 C or merely suspended by it.

Text and provisions

The operative sentence of Clause 8 runs, in the authorized recension of 4 Ember 611:

"No inventory shall be received at the Second Copies until it has been entered a second time by a hand that has not seen the first, and the two entries shall be compared by a third; and where they differ, neither shall be corrected, and both shall stand."

— Ninth Concordance, Annex 9, Clause 8

The provision is unusual in the Tower's corpus in that it forbids correction. Where most annexes prescribe reconciliation of discrepant records, Clause 8 treats divergence as admissible evidence of the floor itself. Two inventories that do not agree are held to describe a floor that did not entirely agree with itself, and the file is deposited with both.

Origin: the Winter Recession of Floor 941

The clause is conventionally traced to the Winter Recession of 608, during which the compilation of floor 941 produced three inventories that disagreed on the number of stairwells, the number of rooms, and the number of rooms containing stairwells. The Office of Vertical Survey had, by custom, retained whichever entry was most legible.

A junior clerk of that office, Perrin Sable, argued in a memorandum of 19 Frost 608 that this custom had been concealing a genuine instability on the floor rather than correcting a clerical one, and that the Tower would be better served by the preservation of the disagreement. The memorandum was rejected on the ground that Sable had not dated it correctly. It was nonetheless circulated, copied, and eventually annexed. Sable was reassigned to Floor 212 and is not recorded as having visited 941 again.

Application and incidents

Compliance with the Silence Rule requires the assignment of a second clerk who can attest, under seal, that they have not read the first entry. The Librarians maintain a small rotating pool for this purpose; the pool is customarily drawn from floors whose subject matter is unrelated to the inventory at hand, so that the second clerk has no independent reason to anticipate the contents of the first.

The rule has failed twice in the recorded period. On Floor 1301, the second clerk was the first clerk's brother, and the depositors' dispute over whether the attestation was valid ran for four years before being closed by the Council of Recensions on grounds that the brother had in fact read nothing. Separately, in the winter of 617, a second clerk on Floor 88 completed an entry that matched the first word for word; the third clerk reported the correspondence as suspicious, and the floor was re-surveyed. The re-survey found one fewer room than either entry had recorded. No correction was made, in accordance with the clause, and all three inventories remain in the file.

Clerks working under Clause 8 are not permitted to discuss the first entry with any other clerk between the assignment and the attestation, including in stairwells.

The dispute with Clause 4 of Annex 7 C

Clause 4 of Annex 7 C superseded Clause 33, Annex Delta and rendered the Debt Servicing protocols of Clause 19 γ advisory. It said nothing about Annex 9. The Bureau of Annex Reconciliation nonetheless issued an opinion in 634 holding that the phrase "and all prior procedures of twofold entry" in the supersession schedule of Clause 4 of Annex 7 C included Clause 8 by description if not by name.

The Office of Vertical Survey objected, noting that Clause 4 of Annex 7 C had been drafted for the validation chain of Annex Delta and that "twofold entry" there referred to the registration of amendments, not floor inventories. The Third Concordance, Clause 11, Annex Gamma — the principal Erasure provision — was cited by both sides within the same year, a circumstance the Council of Recensions described as "not unprecedented and not helpful."

The question remains open. In practice, inventories continue to be entered twice, and the Archive of Second Copies continues to refuse single-entry deposits, on the ground that it has always refused them.

Scholarly disagreement

Commentators divide on whether Clause 8 creates a duty or a description. The Commentary of the Inner Stair, followed by most of the survey offices, holds that the clause imposes an obligation on the depositing clerk. The rival reading, associated with the Recensionists of Floor 2, holds that Clause 8 merely describes what the Archive will accept, and that a clerk who enters an inventory once has done nothing wrong but has produced something the Archive will not take.

The distinction matters chiefly for discipline. Under the first reading, a single-entry clerk is liable to reprimand; under the second, they are simply told to go back and enter it again, which is what usually happens.
