First Protocol Addendum 12.β

First Protocol Addendum 12.β is the twelfth beta-level addendum to the First Spire Delineation Protocols, issued from the Office of Vertical Survey in the survey year 4,112 and revised twice since. Its single operative function is the classification of spires whose existence the survey cannot confirm to its own satisfaction. It is best known for the entry at Clause 9, in which Spire 404 is designated a Non-Consensus Spire — the first such designation ever issued, and still the only one entered at beta level rather than by full protocol amendment.

Origin

The Delineation Protocols were compiled to answer a question the Librarians had grown tired of receiving: whether a spire reported by an expedition is the same spire when reported again by a second expedition. The alpha addenda, 12.α among them, addressed spires that were merely disputed — two survey teams disagreeing over a measurement, a stairwell count, or a bearing. By the winter of 4,108 the survey had accumulated a class of reports that were not disputed so much as unsupported: spires logged by competent surveyors, countersigned at the time, and afterwards found to have no corresponding aperture on any adjoining floor.

The Office's response, drafted largely by Under-Surveyor Maren Holt, was to stop treating absence of evidence as a defect in the report and begin treating it as a property of the spire. Addendum 12.β gives that property a name and a procedure.

"A spire shall be termed Non-Consensus where the survey holds records of its delineation but no concurring delineation, and where the discrepancy is not attributable to instrument, fatigue, or the known drift of the eastern stairwells."

— First Spire Delineation Protocols, Addendum 12.β, Clause 3

The designation of Spire 404

Clause 9 was inserted at the first revision, in 4,114, after three separate delineation parties returned from the north-eastern vent with measurements of the same structure and no agreement as to its floor number. The parties concurred on the spire's height to within four inches and on its material, its weather, and the position of two of its windows; they differed on whether it stood at Floor 404, Floor 405, or "between." Under Clause 3 this is precisely the condition the addendum was written for, and the Office entered the designation without further debate.

The classification carries practical consequences. A Non-Consensus Spire is not counted in the annual vertical inventory, is not assignable to any floor for the purposes of the Concordance of Floors, and may not be cited as a landmark in an expedition's return testimony. Survey parties who sight it are directed to log the sighting and to walk on. Clause 9 closes with a maintenance note added at the second revision: the north-eastern vent is swept on the third day of each month, and parties are asked not to leave chalk marks on the lintel.

Dispute with the Directorate

The addendum's standing has never been fully settled. Addendum 1.7 of the Seventh Addendum to the First Concordance codified the Directorate's primary mandate as the reconciliation of discrepant records, and the Directorate has read this as authority to reconcile Spire 404 by administrative act — that is, to choose a floor and enter it. The Office of Vertical Survey contests the reading, arguing that a Non-Consensus Spire is by definition not a discrepant record but a settled one, and that the Directorate's mandate covers the record, not the spire.

The dispute produced the so-called Question of the Fourth Window, a decade of correspondence concerning whether a spire that cannot be assigned a floor may nonetheless be assigned a window. The Directorate's position, set out at length in the Memorandum on Partial Structures, was that windows are features of spires and not of floors, and therefore survive the designation. The Office replied that a window opens onto something, and that reconciling the window without the floor was "the reconciliation of an aperture without a wall." No resolution was recorded, and the file was suspended from the Ceiling of Pending Motions in 4,131 under the triennial review then in force.

"Where a structure is held to exist and not held to be anywhere, the Board's working presumption regarding undated events shall apply to its features in the order in which they were observed."

Relationship to the Wandering Lemma

A minority reading, advanced by the surveyor Osric Vane in 4,119 and never withdrawn, holds that Addendum 12.β anticipated the observable phenomenon described in the postscript of Addendum 12 of the Second Concordance — the Wandering Lemma — and that Spire 404 is not non-consensus at all but merely in transit. On this view the parties who disagreed about the floor were all correct on the days they measured, and the Office's error lay in treating a moving datum as a fixed one.

The Office has declined to reopen the designation on these grounds. Its published reply notes only that Vane's reading requires the spire to move, that three subsequent sighting parties have reported no movement, and that in any case a designation is a record of what the survey held at the time and is not disturbed by later theories. Vane is recorded as having accepted this with the observation that the parties in question had each visited the vent once.

Legacy and recensions

Addendum 12.β is the only beta-level instrument to have generated a full derivative literature. The Third Addendum to the Delineation Protocols extends its classification to spires reported at a distance greater than two floors, and the office's own Protocol M-2001 adopts its Clause 3 test for purposes unrelated to spires. Three recensions of the addendum circulate; the Third Scribe's recension, designated definitive by the Third Concordance's Fourth Addendum, differs from the Office's sealed copy in the wording of Clause 9, omitting the phrase "and to walk on." The Office regards the omission as scribal.

Copies are held at the Aperture Registry and at the vent station itself, where the article is chained to the wall. Parties are asked not to remove the chain.
