Manifest Verification

Manifest Verification is the formal procedure by which a holding catalogued within the Tower is examined for evidence of manifest presence and, if the evidence is found sufficient, entered onto the manifest register of its floor. It is distinct from the confirmation of internal consistency performed by the Office of Ontic Verification, which concerns whether a concept holds together, rather than whether it is present. The two offices have shared a stairwell at Landing 44-C for sixty-one years and have not, in that time, agreed on a common intake form.

Manifest Verification is initiated by the submission of a Subject Manifest to the Office of Verification, and proceeds by stages set out in Clause IX and amended, variously, by the Fourth Concordance and the Eleventh Concordance. The procedure applies to all holdings regardless of floor, though floors above 900 and below 40 observe the abbreviated schedule described in section 4.

Procedure

A verification proceeds in five stages, recorded on the Verification Docket (VD-2) and countersigned at each stage by the duty Receiving Registrar.

1. Declaration. The petitioner files a Formal Intention to Manifest (FIM-7) together with the completed Form OV-1α. Filing does not itself constitute an intention to verify; the distinction is maintained by the Office of Filing Distinctions and is frequently litigated.
2. Assessment. A Vector of Transit assessment is carried out to establish whether the holding can be said to have arrived from anywhere. Holdings of unclear origin are assessed against the nearest defined aperture, per the Aperture Schedule, Revised.
3. Delineation. The holding is tested against the seven criteria of the Protocol of Manifest Delineation. Six of the seven are pass/fail. The seventh — concerning the persistence of the holding under direct observation — is scored on a nine-point scale, and it is on this scale that most disputes turn.
4. Attestation. A Verification Cadre attends the holding and attests to its presence in the presence of two witnesses, neither of whom may be a member of the cadre, the petitioner, or the holding itself.
5. Appendation. Upon success, the Arrival Sigil is appended to the Form L-29 "Manifest of Arrival" and the holding is entered on the register. The sigil is applied in a single motion; a sigil applied in two motions is void and must be re-attested from stage 3.

The question of weight

Central to the procedure is the threshold value known as Manifest Sigma-Ω, recorded in the Protocol of Manifest Delineation as 87.3 standard stone units. A holding whose attested weight falls below this figure is not, for the purposes of verification, considered manifest, however else it may present.

The Tenth Concordance holds that Manifest Sigma-Ω is a property of the holding and should be measured by the cadre at stage 4. The Fourteenth Concordance holds that it is a property of the floor and should be measured at intake, before the cadre is convened. The two readings produce materially different results for holdings near the threshold, and the Standing Committee on Threshold Disputes has referred the matter to itself four times without resolution. In practice, most cadres record both figures and leave the register ambiguous, which the Indexing Protocols for Non-Manifest Holdings permits under annotation 12.

Outcomes

Verification may conclude in one of four states, all of them recorded on the docket:

Manifest

The holding is present, attested, and entered. It acquires a floor of residence and may be cited in subsequent filings.

Provisional

The holding is present but not yet attested, and must be renewed under the Ritual of Periodic Verification at intervals of no more than nine floors of elapsed record. This is the most common outcome and the least stable.

Static

The holding is recognised as present but immobile, and is governed by the provisions of Static Manifest. A static holding may not be moved between floors without a Transit Manifest.

Unverified

No determination is reached. The holding remains on the non-manifest register and may be re-filed after the lapse of one full catalogue cycle.

Where a holding is found manifest but subsequently cannot be produced for inspection, the Manifest Theory Consortium conducts an audit to determine whether its Certificate of Manifest Visitation was improperly removed. The Consortium's findings are advisory, but its audits have twice caused the reversal of an appendation.

Floors of abbreviated schedule

Above floor 900 and below floor 40, Manifest Verification observes an abbreviated form of the procedure in which stages 2 and 3 are combined and the cadre is reduced to a single attestor. This arrangement dates from the Concordance of the Upper and Lower Margins and was intended as a temporary measure during the reconstruction of the north stairwell. The stairwell was completed in the following decade; the abbreviated schedule was not withdrawn. Several registrars have argued that the schedule's persistence is itself evidence of a holding, and have offered to verify it. The proposal has not been accepted, on the grounds that it would require a cadre to attest to a procedure it is currently performing.

Criticism and revision

The principal criticism of Manifest Verification is that it establishes presence by weight, which favours holdings that are heavy and disadvantages holdings that are not. The School of Manifest Inventory has proposed a volumetric criterion to supplement the threshold, and the Twelfth Concordance makes provision for it in principle. No volumetric cadre has been constituted. The Office of Ontic Verification has declined to comment on the proposal, noting that it concerns presence rather than coherence and is therefore, in its phrase, "not ours."

Revision of the procedure requires a supermajority of the Librarians and a successful Spiral of Manifest Intent, the latter having failed to initiate on three of the last five occasions. The reasons for failure are not recorded, though the Minutes of the Fifth Attempt run to forty pages and conclude only that the spiral was "not at that hour inclined."
