Type B (Intent-Directed)

Definition and standing

Type B (Intent-Directed) is a classification applied to transitional structures within the Tower whose operation is governed by the orientation of a presiding intent rather than by their own material configuration. Where a Type A structure performs its function irrespective of who approaches it, a Type B structure does nothing until it is addressed, and does considerably more than expected once it is. The classification is administrative in origin and remains, in the judgment of the Registrar of Transitional Forms, "descriptive of a procedure that was never fully written down."

Type B is one of four standing classifications under the transitional schedule of the Third Concordance, Clause 397, alongside Type A, Type D, and the disputed Type F. Its immediate relatives in the record include Type B Pause, which concerns the interval preceding activation, and Type 3 and Type-3, both of which describe outcomes rather than mechanisms. Type B describes the mechanism and declines, deliberately, to describe the outcome.

Historical development

The classification entered use during the adjudication of the Dissonance of Vault 12 (winter of the long recension), when Archivist-Proctor Kael was required to determine whether a sealed vestibule on Floor 4,118 had failed to open or had declined to. The distinction proved legally material: a failure was repairable at the cost of the district, while a decline required the issuance of a V-instrument and the signatory's subsequent intent. Kael's ruling — that the vestibule had declined — established the principle that a structure could be the bearer of an addressed will without itself possessing one.

The Adjunct Office of Resonance Damping contested this reading for eleven years, arguing in a series of annexes that intent-directed behaviour was a symptom of proximity to a Type-7 aperture rather than an intrinsic classification. The Bureau of Coincidental Resonance, which oversaw the Adjunct Office, declined to intervene, on the grounds that its own charter did not extend to the naming of things. The dispute was settled administratively rather than intellectually: the Registrar simply continued to use Type B on forms, and the Adjunct Office's objections were filed under Type Γ: Referential Anomaly.

Operation

A Type B structure requires three conditions to function: an address, a direction, and a witness. The address is supplied by the arriving party, the direction by the structure's own gearing or intent-channel, and the witness by a clerk of the appropriate grade, who records what occurred irrespective of whether anyone believes it. Structures lacking a witness will repeat their operation indefinitely, with progressively less care, until the repetition becomes indistinguishable from decay. This phenomenon is catalogued separately as Type Alpha Persistent Insertion.

The direction component is the source of most scholarly disagreement. Under one reading, inherited from the thesis of directed longing advanced by Finnian Borell, the structure orients toward whatever the arriving party most conspicuously fails to want — which explains why Type B doors in the eastern stacks consistently deliver visitors to the record office. Under the opposing reading, set out in Clause 397's third annex, the structure orients toward its own last remembered instruction, and the arriving party merely interrupts a process already in motion. Both readings have been used to justify the same ruling on the same afternoon.

The witness requirement has produced a standing grievance among junior clerks, who note that a Type B operation may be triggered at any hour and that the intervening stretch between activation and record is not counted toward the shift. The grievance was entered most recently by Clerk Sorell Vantis of the Fourth Scriptorium, who observed that she had been witness to forty-one Type B operations in a single night on Floor 6,209 and was credited for none of them. Her account is filed with the Registry of Provisional Intent, pending.

Relation to the pause

Every Type B operation is preceded by a Type B Pause, an interval of indeterminate length during which the structure is aware of being addressed but has not yet committed to a response. The pause is the subject of the only clause in the Third Concordance that specifies a duration in words rather than numbers: "so long as it takes." Attempts to measure the pause using Sphygmomanometers of Intent on Floors 3,770 and 8,441 produced figures that decreased the longer they were observed, which the Bureau of Coincidental Resonance attributed to an damping fault rather than to the instrument.

"A Type B does not wait for you. It has already finished waiting. What you call the pause is its courtesy."

Standing controversies

Two questions remain formally open. The first is whether a Type B structure that has been addressed and has failed to act has refused, erred, or finished. The Third Concordance permits all three readings; the amendment history of Clause 397 shows each being inserted, struck, and reinstated at least twice, most recently in a hand identified with the Registrar's office but unsigned. The second is whether Type B status can be transferred. A certificate issued on Floor 5,004 in the spring of a contested year attempted to do exactly this, naming a departing archive as the addressee rather than the addressed; the Receipt of Anticipatory Intent issued in connection with it was never matched to a submission, and the file remains open under Type 3: Recursive Referral.

Readers intending to encounter a Type B structure should note that the eastern stairwell between Floors 6,206 and 6,212 is unlit on the second Tuesday of every month for repointing, and that the repointing crew does not acknowledge address.
