Tier III: Compositional Authenticity

Definition and Scope

Tier III: Compositional Authenticity is the archival standard by which a Tier III phenomenon is certified as having been composed — that is, assembled from identifiable constituent parts — rather than merely having appeared. The distinction matters because a phenomenon that appeared cannot be disassembled, while one that was composed can be, and the Tower's filing system has no shelf for things that cannot be taken apart. Compositional Authenticity is therefore less a judgement of quality than a statement of addressability: the holding asserts where the thing came from and of what it is made.

The standard is administered jointly by the Bureau of Implementable Abstraction and the Committee for Photonic Authenticity, whose jurisdictions overlap in a manner neither office acknowledges. Practitioners filing under this standard ordinarily proceed through Tier Iii Containment Amp Reformation before certification, though the order of operations is disputed (see Disagreement, below).

Procedure

Certification proceeds in three stages, each attested by a distinct seal. In the first, the filing clerk establishes the phenomenon's constituent inventory — the list of materials, resonances, or propositions of which it is claimed to consist. In the second, the inventory is tested against the phenomenon's observed behaviour; a composition that cannot survive this test is returned to the inventory stage without prejudice. In the third, the clerk attests that the constituent parts, taken together and in the order listed, would produce the phenomenon and no other.

The third stage is where most filings fail. A composition that produces the phenomenon is not sufficient; it must exclude every neighbouring phenomenon of the same sub-tier. Clerk Odile Marrant, who held the third-stage desk on Floor 611 for nineteen years, returned an estimated four thousand compositions on this ground alone. Her marginal note on one such return — "it makes the thing, but it also makes the thing next to it" — has been recopied into the instructional front matter of every subsequent edition of the certification form, over her written objection.

A certified composition is entered into the register with a closing statement in the following form, of which the register holds some eleven thousand examples:

"Composed of seven parts, in the order stated, and of no eighth part. The seventh part is not to be examined separately; it is structural."

— Compositional Authenticity Register, entry 8,204, sealed under Clause III

The prohibition on separate examination of structural parts is not a matter of secrecy. Parts so designated collapse into indeterminate form when isolated, and the resulting fragment cannot be re-filed.

Disagreement Among the Concordances

Concordance III-44, Annex B requires that any Tier III phenomenon submitted for certification first pass through the full cycle of demonstration prescribed in Tier III: Demonstrative Models, and only thereafter be assessed for composition. Concordance III itself, however, provides at its ninth article that a phenomenon's composition is established "at the moment of its first description, and not after," which appears to place compositional assessment before demonstration rather than after it.

The two readings have never been reconciled. The Librarian Consensus has twice declined to rule, on the ground that ruling would imply one of the documents was mistaken. In practice most offices follow Annex B and backdate the compositional finding to the date of first description, a workaround first recorded by the Office of Retroactive Sealing and now so widespread that filings in the correct order are treated as irregular.

A minority position, associated with the Literalist school and with the writings of Marn III, holds that a composition established after the fact is not a composition but a reconstruction, and should be certified as Tier III only under protest and with the seal struck through. No struck-through certification has ever been accepted for filing, but the protest form remains in print.

Sub-tier Gamma and Protocol Sigma-7

Resonances classified under Sub-tier Gamma present particular difficulty, since they may be composed of parts that are themselves compositions. These are documented according to the framework set out in Tier III: Demonstrative Models and contextualized within Protocol Sigma-7, whose treatment of nested constituents is acknowledged to be circular. The standard's position is that the circularity is stable, and that a stable circularity may be certified; the register records forty-one such certifications, of which thirty-nine remain on the shelf and two have been withdrawn without explanation.

Where a composition is contested between two filers, the dispute is referred to Attribution Arbitration for Contested Cantatas, whose remit was extended to all composed phenomena in 24-019 and never formally narrowed. The arbitration's rulings are binding on the filers and advisory on the shelf.

Relationship to Recursive Authenticity

Compositional Authenticity is frequently confused with the Principle of Recursive Authenticity, under which a document's authenticity is established by its own attestation of itself. The two standards are distinct. Recursive Authenticity asks whether a holding may vouch for itself; Compositional Authenticity asks only of what it is made. A phenomenon may satisfy one and not the other, and the register contains a small number of holdings — the count is given as six, though two entries are duplicated — that satisfy neither and are retained for comparison.

Filings that invoke both standards must be submitted on Form 1747-Ω and are processed at the fourth-stage desk, which is not presently staffed.

Practical Notes

Certification is conducted on the filing floor and may not be removed to the stairwells. Clerks are reminded that a constituent inventory is a finding, not an opinion, and should not be amended to agree with a colleague's. Sealing wax is issued at the start of each quarter and is not replaced if lost. The third-stage desk on Floor 611 remains open, though the sign above it still reads Compositional Authenticity, Second Stage, a discrepancy maintained for reasons the office has never set down in writing.

Holdings certified under this standard are shelved in Annex III and cross-referenced in Volume III: Luminous Gradients where the composition includes a photic element. Enquiries regarding withdrawn certifications should be directed to the Office of Retroactive Sealing, which will confirm that the withdrawal occurred and decline to say why.
