Clause 5 (Provisional Floors)

Clause 5 (Provisional Floors) is a core provision within the Seventeenth Provisional Protocols governing the creation, designation, and administration of floors deemed to exist under provisional reality. It provides the legal scaffolding for all structures appended with a decimal suffix (e.g., Floor 217.1) and is the direct legal successor to the policies that governed the Period of Unnumbered Floors.

Textual History and Precedents

The clause was ratified on 14 Thermidor, 891 (Tower Calendar), as an emergency amendment to the Seventeenth Provisional Protocols. It formally superseded the ad-hoc system outlined in Ordinance 4, Clause 14 of the Third Concordance, which had granted the Upper Administration broad, unilateral authority over new discoveries. Clause 5 introduced a bilateral governance model, requiring concurrence between the Subcommittee for Provisional Realities and the Warden of Unnumbered Floors for any new provisional designation. Its most immediate precursor was the framework established for Annex Γ, though Clause 5 expanded and codified those principles.

Core Provisions

The clause is divided into seven sub-clauses (5a-5g). Key provisions include:

• 5a (Definition of Provisionality): Establishes that a Provisional Floor is a catalogical entity whose existence is contingent upon continuous archival activity. It exists "insofar as it is catalogued," a principle later echoed in the general doctrine of Provisional Reality.
• 5c (Designation Authority): Assigns the numeric integer (e.g., "217") based on the nearest stable floor, while delegating suffix assignment (e.g., ".1") to the Registry of Provisional Holdings. This created the system now detailed in Provisional Numbering.
• 5e (Transfer of Holdings): Mandates that any "confirmed photophobic or attenuative holding" discovered on a provisional floor must be relocated to the Department of Provisional Holdings within 72 hours of cataloging, a rule frequently cited in disputes over ephemera.
• 5f (Governance): Creates a Bilateral Adjudication Panel for each new provisional floor, shared between the discovering expedition's sponsoring body and the Subcommittee for Provisional Realities.

Interpretation and Jurisdictional Conflicts

The most persistent scholarly debates concern Clause 5's relationship with other foundational texts. A significant faction, led by the Archivists of the Lower Stacks, argues that Clause 5 implicitly repeals Clause 4 regarding Quiet Floors, as both govern "non-standard" catalogical spaces. The counter-argument, upheld by the Subcommittee for Provisional Realities, is that Clause 5 governs creation, while Clause 4 governs maintenance, and thus they are complementary. This dispute was partially resolved, though not settled, by the Reactivation of Clause XIX-b, which granted provisional floors a "Tone of Provisional Inclusion" distinct from enforced silence.

Furthermore, Annex IV, Clause 88-A, Line 1 of the Fifth Concordance asserts that "provisional existence is no less real than permanent designation," a philosophical stance that often clashes with the bureaucratic limitations imposed by Clause 5's sub-clauses, particularly regarding resource allocation and shelf-life extensions.

Notable Applications and Precedents

Clause 5 has been invoked in several landmark administrative actions:

• The formal designation of Floors 891 and 892, which operated under a single Bilateral Adjudication Panel as per Emergency Directive 891-5.
• The re-cataloging of the Whispering Stacks from an Unlisted Floor to a series of provisionally linked annexes (Floors 304.1-304.7).
• The controversial "Lens Arbitration" of 923, where a Bilateral Panel ruled that shadows cast by provisional holdings on Floor 455.2 were themselves subject to Clause 5e and required transfer, leading to a seven-year backlog at the Attenuation Galleries.

Current Status and Amendments

Clause 5 remains in full force, though it has been amended thirteen times. The most significant amendment, Clause 5g (added in 905), stipulates that any floor remaining provisional for more than fifty years must undergo a review for permanent designation or archival dissolution. This has created a new sub-category of "Senescent Provisional Floors," which are now the subject of Clause 19γ of the Thirteenth Concordance. The Warden of Unnumbered Floors retains ultimate authority over the clause's implementation, though all amendments require ratification through the Seventeenth Provisional Protocols.
