Ingress Verification

Ingress Verification is the formal determination that an Ingress Point has been correctly recorded, correctly located, and is what the record says it is. It is distinct from Ingress Logging, which produces the record, and from Ingress Tabulation, which orders it; verification asks only whether the record can be trusted, and is performed by the Verification Cadres under authority delegated by the Bureau of Ingress Validation. A verified ingress point is entered in the Register of Confirmed Apertures. An unverified one remains on the Provisional Roll, where some points have remained since the eleventh century.

The procedure is governed principally by the Manual of Ingress, Chapter 9, and by the Tenth Concordance, Clause 44, which designates Floor 892 as a procedural buffer and material staging area for the verification of non-sequential ingress. The two instruments are not in agreement about what verification consists of. The Manual treats it as a documentary exercise: three Cadre officers compare the ingress record against the Tower's catalogues and against the Manual of Anomalous Ingress, which is consulted during Cross-Reference Verification to identify linguistic or conceptual anomalies. The Tenth Concordance, read plainly, treats it as a physical exercise, requiring that the aperture be approached, measured, and struck once with a brass rod. Most Cadres perform both and record only the documentary half.

Origins and the winter of Floor 892

Verification as a separate procedure dates from the reorganisation that followed the Ingress Amp Isolation disputes of the previous century, when it became clear that a point could be stable, logged, isolated and still be in the wrong place. The first Cadres were drawn from the Department of Verification Amp Lineage, which has contested their independence ever since on the grounds that a body which verifies apertures should not also inherit from the offices that once measured them.

The practice was fixed in the winter of the year the Register records as 1174, when a Cadre working Floor 892 verified eleven ingress points in a single shift and discovered, on the following morning, that the floor had been renumbered overnight and that all eleven were now in a corridor that did not appear on any plan. The episode produced the rule still cited in Cadre instruction: no aperture may be verified on a floor whose number is under revision. The clerk who raised the objection, a junior verifier named Halvard Senn, was reprimanded for delay and later commended for the same delay in the same document.

Procedure

Verification begins with a check of the ingress record against the local catalogue, then proceeds to Cross-Reference Verification, in which the Cadre establishes that the point's described characteristics correspond to a category the Tower recognises. Where the description resists categorisation, the Manual of Anomalous Ingress is applied and the point is marked as anomalous rather than rejected; anomalies are verified as anomalies, which is a separate finding and carries a red seal.

The Cadre then confirms the point's claim under Priority Ingress, which requires that no earlier lawful claim exists. This is the slowest stage, because Priority records are held in three places and reconciled in a fourth. Cadres are permitted to verify a claim provisionally and to note the discrepancy in the margin. Roughly a fifth of all verifications carry such a marginal note.

Physical confirmation, where undertaken, follows the Tenth Concordance: approach, measurement, single strike. The brass rods are issued from Floor 892 and are not permitted below Floor 300, on the grounds that the lower floors are damp and the rods corrode. A Cadre that loses a rod must file a loss statement before leaving the staging area.

Relation to isolation and tabulation

Verification is normally preceded by Ingress Amp Isolation, which measures and contains the point's phenomenological output, and is normally followed by Ingress Tabulation, which must be initiated within seven working days of a successful isolation. Verification sits between them and is not itself bounded by a deadline. This asymmetry is much resented. The Manual of Ingress requires verification to be completed "in a timely fashion" and nowhere defines the term; the Third Concordance defines it as eleven working days; the Tenth Concordance does not mention verification at all except in Clause 44, and its silence has been read as absolute discretion.

In practice a point may be isolated, verified, and then held unverified-in-fact for years while its Tabulation is attempted against catalogues that do not yet contain its category. The Bureau of Ingress Validation maintains that this is a Tabulation problem and declines to hear appeals about verification.

Disputed questions

The chief scholarly dispute concerns the status of verification where the point has been deaccessioned. The Acquisition and Deaccessioning protocols hold that a removed point retains its verified status for the purpose of the record, since the record describes what was seen and not what remains. The Fourth Recension of the Manual of Ingress, favoured by the Cadres, holds the opposite: that verification attaches to the aperture and lapses with it, and that a deaccessioned point is therefore unverified by definition and may not be cited.

"An aperture that is no longer there is not an aperture that was never there; the record stands, and the Cadre has nothing further to do."

A second dispute, older and less civil, concerns whether the Cadres may verify one another's work. The Bureau maintains that they may not, and that cross-verification is the whole purpose of a Cadre; the Department of Verification Amp Lineage maintains that a Cadre verifying a Cadre is a lineage question and falls to the Department. The question has been referred to Concordance four times and has never been settled, though Safety Ordinance 45 is cited by both sides.

Record of findings

Findings are recorded on Form 7-Δ and sealed in triplicate. The forms are stored on Floor 892 for a period of ninety days, after which they are moved to a floor determined by the number on the seal. The distribution below is drawn from the Cadre return for the most recent complete year.

• Verified, confirmed — 1,412
• Verified, anomalous — 96
• Verified, provisional, with marginal note — 331
• Refused for revision of floor number — 18
• Rod not returned — 1
