Floor 7,117 (The Ceiling Array)

Description

Floor 7,117, designated in the registers as The Ceiling Array, is a catalogued floor of the Tower whose principal function is the suspension and filing of notices requiring the attention of two or more certifying bodies simultaneously. It is the exclusive locus of filing for Form 7,117-δ. The floor is distinguished by a dense grid of galvanized hooks, from which suspended notices hang in tiers reported by the Second Measuring Party (survey of the 3rd recension of the Standing Register of Ceiling Heights) to descend 4.12 metres below the nominal ceiling line before clearing the walkways.

The floor's ceiling height is recorded as 6.80 metres in the Standing Register of Ceiling Heights, a figure disputed by the annotator of Annex 9, who maintains that the hooks themselves constitute part of the ceiling for registration purposes and that the effective height is therefore 2.68 metres. No ruling has been issued.

Location and access

Floor 7,117 is reached by the Western Stair of the Upper Ledger, which terminates without landing on the Array's north-west apron. Access is unrestricted to clerks of Grade III and above; visitors below Grade III are admitted only in the company of a filing clerk and are reminded that the hooks are load-bearing and not to be swung from.

The numbering of the floor has attracted sustained scrutiny, as it sits far outside any sequence yet reconstructed for the Tower. The Bureau of Numerical Concordance has proposed that 7,117 be read as a date rather than a position, an interpretation rejected by the Seventh Metalwrights on the grounds that no floor plaque they have cast bears a year.

Form 7,117-δ

The floor's principal instrument, Form 7,117-δ, serves to document and initiate a procedural impasse where two certifying bodies have issued findings that cannot both stand. It is filed only on or from this floor, and once filed is suspended from a hook until a resolution is brokered.

The most active recurring use of the instrument is in disputes between the Guild of Theoretical Mechanics and the Guild of Exactitude, whose competing certifications of load tolerances have produced eleven open notices as of the last audit. The notices hang together in a block on the eastern grid, and the odour of them — described in the custodial log for the winter of the 11th recension as "sharp, like struck flint" — has never been satisfactorily explained.

The suspension procedure is prescribed by the Third Concordance, Annex 4:

"The notice shall be hung, and not laid, and not propped, and not folded into the grating, though the grating will take it."

— Third Concordance, Annex 4, clause ii

Related structures

The Ceiling Array's grid pattern is often compared to the Ceiling of Pending Motions on Floor 88, though the two differ in material and function: the Ceiling of Pending Motions is a casting of dull, refractive alloy associated with the Thorne Ceiling, whereas the Array is wrought iron and galvanised wire. A further comparison is drawn with the Capillary Array on Floor 881, which likewise distributes matter downward by suspension, though by pressure rather than by hook.

Below Floor 7,117, in the shaft between it and the next numbered landing, the Pneumatic Conduit Array passes without touching the floor's structure. Notices that work free from their hooks and fall into this shaft are considered lost, and are reissued rather than retrieved; the practice dates from the incident of the 9th recension in which a retrieving clerk became wedged and had to be decanted.

Disputes

Whether Floor 7,117 lies above or below the Thorne Ceiling — the notational limit beyond which no floor may be catalogued without a Structural Integrity Waiver — is contested. The Bureau of Numerical Concordance places it well above; the Thorne Ceiling maintenance corps, administered by Clerk-Superior Aris Thorne, insists the limit is a ceiling and not a floor number, and therefore does not apply to any floor at all. Both positions have been entered into the record, and neither has been withdrawn.

A second disagreement concerns the ownership of the hooks. The Seventh Metalwrights hold that cast fixtures belong to their jurisdiction by right of casting, citing the precedent set by the Thorne Ceiling Plaque; the custodial staff servicing the Rotating Resonance Array on a weekly cycle counter that hooks in continuous use revert to the users. The matter is currently filed on Floor 7,117 itself, where the notice hangs from Hook 41-B.

Custody

Custody of the Array is shared uneasily between the Bureau of Numerical Concordance, which holds the grid map, and the filing clerks, who hold the notices. The last complete grid survey was conducted in the 11th recension and found 4,096 hooks, of which 312 were empty, 188 occupied by notices of expired impasse, and 1 by a set of keys belonging to no identified office.

The floor is swept on alternate mornings. The sweepers are instructed not to disturb notices below the second tier, as dislodging them obliges the clerk of record to reissue the form and restart the impasse clock — a rule instituted after the winter of the 10th recension, when a single enthusiastic sweeping ended a dispute that had been considered close to resolution.
