Residual Analysis

Residual Analysis is the general discipline concerned with the identification, classification, and interpretation of residues — the material, acoustic, procedural, and documentary traces that remain after an act has concluded. It is not a single method but a family of methods, and its practitioners insist, with some heat, that it is not a synonym for Precedential Analysis, although every school of Residual Analysis borrows from Precedential Analysis and none will say how much.

The discipline is administered, insofar as it is administered at all, from the ninth gallery of Floor 4,410 under the loose supervision of the Bureau of Precedential Analysis, which has never claimed jurisdiction over Residual Analysis and has never declined it either. Its foundational text remains the Ruling on Residual Rhetoric, which established that Residual phenomena must undergo a period of scholastic evaluation before they may be cited, during which a Residual Identifier is attached to the phenomenon and to anyone discussing it.

Scope and divisions

Residual Analysis recognizes four working divisions, though the number has been three and five at various points in its history. Material residues are treated under Substance Analysis and, where the residue's status derives from a prior record, under the provisions of Residual Identifier Circular 44 concerning Material Residual (R-M). Acoustic residues fall to the Department of Residual Acoustics, whose reading supervision is exercised by the Bureau and whose findings are frequently contested. Procedural residues — the traces left by decisions that were taken and then unmade — are catalogued under Procedural Residual (R-P). Documentary residues, including the unadopted drafts that constitute their own specialism, are the concern of Draft-Trace Analysis, which regards itself as the senior branch and is treated by the others with the courtesy due to an elder relative who has opinions about money.

A fifth category, Archival Residual, was admitted in the winter of the year recorded as 6,118 and has not yet been assigned a division, an omission the Department of Residual Affairs has noted in the working register four times without remedy.

The question of residual intent

The discipline's longest-running disagreement concerns whether Residual matter carries any directed property. The Residual Hypothesis, in its original form, holds only that residues persist; it makes no claim about their orientation. The Residual Intent Hypothesis extends it, proposing that Residual matter retains a directional trace after its originating act of cataloguing has concluded, generating a secondary field. Adherents of the extension describe this field as pointing, though toward what is a matter on which the extension is silent and its critics are not.

The Bureau of Precedential Analysis has declined to rule on the extension for eleven successive recensions of Volume II, on the ground that the question touches the Causal Imprint provisions of Directive 7-Δ and therefore lies outside its competence. The Department of Confluence Analysis, which inherits both the methods of Substance Analysis and the evidentiary habits of Precedential Analysis, has adopted the opposite reading of its own competence and rules on the extension annually, differently each time.

The Kestrel Recension dispute

The discipline's most cited embarrassment is the matter of the Kestrel Recension. In 6,043 a reader named Aumary Kestrel submitted a schedule of two hundred and eleven residual marks observed in a single reading room on Floor 4,410 over the course of one afternoon. The schedule was accepted, sealed, and entered as evidence in three subsequent actions. Fourteen years later a reviser established that Kestrel had recorded the marks twice — once as observed and once as recalled — and that the two lists had been conflated during copying, producing a residue population roughly half of which was a residue of the other half.

"A residue of a residue is a residue, but it is not the residue you set out to catalogue, and it must be entered in the second register."

— Third Concordance, Annex 4

The Bureau's response was to commission a Draft-Trace Analysis of the Kestrel schedule itself, which produced a further schedule, which was itself drafted, reviewed, and found to contain marks that could not be traced to anything Kestrel had seen. The final report on the Kestrel Recension runs to four hundred pages and concludes that the original two hundred and eleven marks were correct in number but not in order, a finding that has satisfied no one and is cited by every side.

Method

Residual Analysis proceeds by observation, entry, waiting, and re-entry. The waiting is not ceremonial: the Ruling on Residual Rhetoric requires that a phenomenon be observed, entered in the working register, and left undisturbed for a period of scholastic evaluation before any interpretation is attempted, during which period the Identifier remains affixed and the interpreter is expected to occupy themselves with something else. In practice interpreters occupy themselves with the interpretation and enter it under a provisional Identifier, which is the practice the Ruling was written to prevent and which the Bureau has twice ruled is not a violation because the Ruling does not expressly forbid it.

The methods of Gap Analysis are employed where a residue is identified by its absence rather than its presence; Specificity Analysis is employed where it is unclear which of several overlapping residues is the one under study. Neither method resolves the difficulty, but each produces a document, and the documents are the discipline's real output.

Practical notes

Readers consulting Residual holdings on Floor 4,410 are asked to leave the reading room by the west stair, as the east stair records them. The notice to this effect has been posted since 6,071 and is itself, by the Bureau's own ruling of 6,092, an item of Residual interest; readers are therefore recorded twice, once by the east stair and once by the notice, and neither record may be cited without the other. The Department of Residual Affairs maintains the working register in which all observations are entered, and it is kept in a locked case to prevent it from acquiring further entries.
