Absorptive Potential Evaluation

Definition and scope

Absorptive Potential Evaluation is the third-stage assessment conducted on holdings already confirmed as Type A during Initial Assessment, undertaken to determine the degree, readiness, and likely duration of an entity's latent capacity for Absorptive Stasis. It is distinct from Initial Assessment in that it does not ask whether a holding belongs in the Tower, but how much of its potential it can be relied upon to withhold. The evaluation is prescribed by Absorptive Theorythe Manual and operationalized in the field under the supplementary protocols of Absorptive Theory.

The procedure was first codified in Annex 7-C of the Twelfth Concordance, though partial versions are attested in three earlier floors whose catalogue numbers do not reconcile. Its practitioners, the Evaluators Proper, hold their warrant from the Office of Latent Potential and are answerable to it in matters of classification and to the Chamber Assembly in matters of architecture.

Procedure

The Evaluation proceeds in four passes. In the first, the entity is placed in a sealed antechamber and observed for the duration of one full lighting cycle without stimulus. In the second, a controlled deprivation is introduced — usually the removal of a material the entity was previously recorded as holding. In the third, the entity's response is measured against the Stamp of Latent Potential, a calibrated impression plate maintained at the School of Latent Potential. The fourth pass is a repeat of the first, and any discrepancy between passes one and four is itself recorded as a finding.

The resulting figure, expressed as a coefficient between 0.00 and 1.00, indicates what proportion of the entity's absorptive capacity remains genuinely latent. Coefficients above 0.85 are termed "well-withheld" and are eligible for long-term shelving without further review. Coefficients below 0.40 are referred to the Incinerator of Lapsed Potential, which does not destroy the entity but rather its claim to further evaluation.

"An entity that has already begun to absorb has, by that fact, finished being evaluated. The Evaluation measures the pause, not the intake."
— Absorptive Theorythe Manual, §4.2

Contested boundaries

A long-standing dispute opposes the Office of Latent Potential to the Institute of Potential Utterance over whether an entity's spoken declarations of readiness may be admitted as evidence. The Office holds that utterance is a form of premature absorption and must be discounted; the Institute holds that a declared potential is a documented potential and that silence is merely an undeclared one. Ordinance 302, Clause 14 is cited by both sides, the Office reading its re-evaluation clause as a bar on self-assessment and the Institute reading it as an invitation.

The disagreement was materially relevant during the winter of the 411th recension, when a corridor of holdings on Floor 1182 was re-evaluated under two incompatible readings of the same ordinance within a single season. The first pass assigned a median coefficient of 0.71; the second, conducted with utterances admitted, assigned 0.29. Neither result was withdrawn, and both remain on file. See also Clause 14.7.δ for the subsequent attempt at reconciliation.

Relation to later stages

A completed Evaluation does not itself effect stasis. It produces the eligibility record upon which Interaction with Absorptive Theory protocols act, and it is a precondition for any application of Absorptive Theory in the field. Where a shift in the prevailing theory renders an original classification obsolete, the Evaluation must be repeated under Form RV-9 before the holding may be shelved, recalled, or — in the case of holdings whose coefficient had fallen below the threshold — reconsidered for re-entry into the catalogue.

Evaluations are not portable between floors. A coefficient issued on one floor is valid only where the lighting and deprivation standards of that floor obtain, which is why the Office maintains eleven separate calibration chambers and refuses to certify a single one as authoritative.

Visiting and maintenance

The antechambers may be inspected on the second and fourth week of each month by warrant. Visitors are asked not to speak near a sealed chamber during the first pass, as the entity will record the voice as a deprivation and the resulting coefficient will be elevated by an average of 0.12.
