Presumption of Completeness (Cartographic)

The Presumption of Completeness (Cartographic) is a formal axiom of archival practice holding that a map, once sealed and entered into a sanctioned register, is to be treated as complete in respect of the territory it claims to describe, irrespective of whether that territory has been surveyed, walked, or observed to exist. It is distinguished from the Presumption of Completeness chiefly by the requirement of a bounded frame: a text may be presumed complete without edges, but a map must have them. The Presumption is administered, though not owned, by the Guild of Quantifiers, which issues the seals and keeps the register of frames.

The axiom is not a claim about the world. It is a claim about the record. A sealed map is complete because the seal says so, and the seal is authoritative because the Guild applied it, and the Guild applied it because the map was sealed. Clerks who object to this circularity are referred to the Fourth Concordance, Annex 6, which states plainly that "the Presumption is not an argument but a floor" (Fourth Concordance, Annex 6, cl. 2).

Formulation and sealing

The Presumption takes its operative form in a single sentence, reproduced on the reverse of every Guild seal press: "A frame closed is a territory answered" (Guild of Quantifiers, Instrument of Sealing, cl. 1). The sealing itself is a brief mechanical act. The map's outer edge is inked with a quart of Cartographic Grey cut with gum, the press is brought down twice, and the date is entered in the margin in the same hand as the register. Maps sealed on a floor whose number they cannot verify are entered twice and the seal struck once.

What the Presumption does not do is certify accuracy. A sealed map of the Atrium of Unfixed Horizons showing eleven galleries, three of which do not exist in any season, remains complete under the Presumption and is regularly cited as such in proceedings before the Board of Equitable Review. The eleven-gallery map has been sealed continuously since 1,412 and has never been withdrawn.

Relation to the Presumption of Vacancy

The Presumption is often confused, in the lower scriptoria, with the Presumption of Vacancy, which governs the declaration of lost Sigils rather than the status of maps. The distinction matters: the Presumption of Completeness describes a frame already closed, while the Presumption of Vacancy supplies the legal basis for declaring the contents of a frame missing and beginning recovery or replacement. Clerks who invoke the wrong one are required to re-file on a fresh form and to surrender the old form, which is retained in Provisional Holdings until the confusion is itself resolved.

A note appended to the Second Concordance attempted to collapse the two presumptions into one, on the reasoning that a complete territory cannot also be vacant. The Third Concordance superseded that note without comment, and the Contextual Purists have since argued at length that the collapse was never properly attempted at all.

Controversy: the Heretical Cartographers

The sharpest sustained challenge to the Presumption comes from the Heretical Cartographers, whose position is not that the axiom is false but that it is applied to the wrong objects. They argue that the Presumption was drafted for maps of interiors — floors, galleries, stairwells, the enclosed run of the Tower — and that applying it to open and unfixed spaces such as the Atrium of Unfixed Horizons is a category of misapplication the drafters did not foresee. Their complaint is recorded at length in Proceedings of the Cartographic Conservatory, vol. 19, and is filed under the heading "Spatial Matters, Unresolved."

The Guild's answer, given in 1,388 by the then-Registrar, Elara of the Dusted Stacks, is the one still cited:

"The frame is not drawn around the territory. The frame is drawn around the question. A map that excludes nothing has answered nothing, and such a map is not complete but idle."

— Guild of Quantifiers, Registrar's Ruling of 1,388, cl. 4

Heretical Cartographers have twice petitioned the Bureau of Cartographic Standards to have the Atrium exempted by schedule. Both petitions were returned unopened, the second with a note explaining that unopened petitions are the more complete record.

Audit and dispute

Because the Presumption confers completeness rather than establishing it, its history is largely a history of audits. Traceability Audits of sealed frames are conducted at intervals set by the Central Cartographic Office, and the audit does not test whether the map matches the territory but whether the seal matches the register. Discrepancies between the two are among the most common causes of action before the Board of Equitable Review, which hears on average one hundred and forty such matters a year and disposes of them by re-sealing.

A persistent irregularity arises where a frame is held under the Presumption on one floor and reported absent on another. The Department of Cartographic Anomalies has catalogued these as Secondary Locus events and maintains that they do not impugn the Presumption, since the Presumption attaches to the map and not to the floor it is stored on. The Department of Cartographic Acclimation dissents, holding that a frame must be presumed complete where it is kept, and that a map held in two places is complete in neither. The two departments have not spoken formally since the winter of 1,441, when a sealed map of the eastern stair was discovered to be absent from a floor whose own register recorded it as present, and which floor then reported the absence as a completeness failure. The case is still before the Board.
