Potential Resonance Assessment

Potential Resonance Assessment is the formal procedure by which a phenomenon deemed pre-real is measured, graded, and assigned a standing within the Tower's referential order. It is distinguished from its near neighbour, the Initial Assessment, in that the Initial Assessment asks only whether a thing may be catalogued at all, whereas Potential Resonance Assessment asks how strongly the uncatalogued thing insists upon its own eventual cataloguing. The procedure is administered by the Resonance Assessment Guild under the authority of The Statute of Latent Potential, whose Clause 14.7.δ establishes that "the potential resonance of a subject is as materially significant as its current manifestation" (Clause 14.7.δ, second recension).

In practice the assessment proceeds by instrument. The Potential Resonator Array is the calibrated apparatus of record, though older assessments were conducted with the Resonance Tuning Fork and, on floors where the humidity is uncontrolled, with Resonance Hygrometers read against the Vect Resonance Model. Results are entered on Form Φ-7 and sealed with the Stamp of Latent Potential.

Origins and the Metrices dispute

The procedure descends from the Metrices of Intent, commissioned from the Academy of Latent Potential in the year recorded only as the Ninth Recension. The Academy's charge was to quantify potential resonance without ever resolving it, a task it discharged with such thoroughness that the resulting instruments could detect a pre-real subject but not identify it. A note in the Academy's register for that period reads simply: "We have built a scale with no pan. It weighs beautifully." (Academy of Latent Potential, Register of Instruments, folio 212.)

Disagreement persists over whether the Metrices or the later Harmonic Resonance Protocols constitute the true basis of the assessment. The Guild holds for the Metrices; the School of Latent Potential holds for the Protocols, on the grounds that the Metrices measure intent while the Protocols measure resonance, and that only one of these can be printed on a form.

The Lambda threshold and referral

Assessments are graded on the Gresham Scale, and any subject registering Lambda or above is removed from the ordinary queue and referred under Vector Beta, a framework triggered during contextualization in Protocol Sigma-7. Referral is not a promotion. Subjects so referred are held in un-rung jurisdiction until the Division of Terminal Verifications completes its terminal assessment, which for subjects of extreme recursive potential has been known to take eleven winters.

The Assessment of Predictive Mass reads accumulated poliad trends as an indicator of possible Conceptual Motility events, and its returns are appended to every Potential Resonance Assessment over Lambda as a matter of course. The appendices are rarely read. In the winter of the Fourth Recension, a clerk of the Third Scriptorium, one Halloway, appended a predictive-mass return to the wrong form and thereby referred a stairwell on Floor 84 for terminal verification. The stairwell was assessed, found to possess considerable latent potential, and returned to service with a Lambda rating painted beside the fourth landing. It remained there for sixty years. Halloway's grievance, that no one had thanked him, is preserved in the Scriptorium's minutes and is the only surviving record of the incident.

Conduct of the assessment

The assessor first takes a Spectral Baseline Capture of the floor on which the subject is reported, since a resonance measured against an unstabilised floor is void under Seventh Concordance, Clause 7. The subject is then exposed to the Array at three velocities in accordance with the Three-Velocity system, and the resulting trace is compared against the Harmonic Assessment archive. Where the trace indicates potential to generate or amplify phenomena such as The Substrate Hum, the assessor notes the possibility and proceeds; the Hum itself is never assessed directly, as it has no floor of origin.

Assessors are reminded that no instrument may be left running overnight on a floor above the fortieth, and that the Tuning Fork is to be returned to its case.

Contradiction between the Concordances

The principal scholarly dispute concerns what an assessment actually establishes. Seventh Concordance, Clause 7 holds that a subject's potential resonance is a property of the subject. The Fourth Concordance, Annex 2, holds that it is a property of the assessor's expectation, and that a sufficiently patient assessor will resonate any subject at all. The Doctrine of Predictive Quarantine was promulgated to bridge the two positions and instead widened the gap, since it quarantines subjects on the strength of an expectation the Fourth Concordance says is not real.

"The clause quarantines what the annex says does not exist. We have complied by quarantining nothing and recording everything."

No amendment has resolved the matter. The Referential Impact Assessment required for any such amendment has been drafted four times and withdrawn four times, on each occasion because the amendment's collateral references included the Referential Impact Assessment itself.

Records and current standing

Completed assessments are held by the Resonance Assessment Guild on Resonance Foil, which preserves the textual potential field of the form even where the form was never fully filled. Approximately one assessment in nine is legible only in potential, and these are consulted by appointment.

As of the current recension, Potential Resonance Assessment remains the ordinary route by which a pre-real subject enters the archive. The Guild notes that no assessment has ever been reversed, that none has been shown to have been necessary, and that the practice continues.
