Post-Incident Review (Phase IV)

Post-Incident Review (Phase IV) is the fourth and terminal stage of the Tower's standard incident-handling sequence, convened after Trigger Phase, through the Triangulation and Examination stages, and following the delivery of the Phase Delta: Verdict. Where the Verdict establishes what occurred, Phase IV establishes what the Tower will say occurred, and in what hand, and to whom, and at what cost per folio. It is the only phase of the sequence not legally compelled: a Review may be declined, and frequently is, but a Review that is convened cannot be closed except by the production of a Review Record, and no Review Record has been lawfully destroyed since the Second Concordance.

Seat and Convening

Phase IV is convened by the Office of Post-Ratification Affairs, which issues a Writ of Reckoning bearing the floor number of the incident and the signature of two Librarians of not less than the seventh band. The Review sits in the nearest reading room to the incident floor, on the principle — set down in Fourth Concordance, Annex 9 — that testimony should not travel further than the staircase it concerns. Where no reading room survives, the Review sits on the stairs, and its findings are recorded as having been taken "at an elevation," a phrase whose legal weight took the Clerks of the Spiral Body some two hundred years to establish.

Convening does not imply fault. The Writ carries the inscription ad inveniendum, non ad damnandum — for finding out, not for damning — which Junior Librarian Aris is recorded as having read aloud in its entirety before the Review of the Silent Stacks, to the visible irritation of the chair.

Composition of the Panel

A Review panel consists of three sitting Librarians, one recording Clerk of the Spiral Body, and one "witness to the silence" — a junior officer present only to confirm that moments of hesitation in testimony are faithfully entered and not mis-transcribed as agreement. The office was created after the Incident of the Wandering Addendum, in which the omission of a single pause was argued to have altered the sense of an entire annex.

Panels are seated by rota. The rota is drawn from a ledger kept in the Hall of Reckonings, and disputes over it are so routine that the Post of Recursive Oversight maintains a standing sub-office for their resolution. In the winter of 884, a clerical transposition seated the same three Librarians on every panel for six consecutive weeks. The resulting Recensions, known informally as the Winter Recensions, were never overturned, and one of them remains the sole authority on the correct method of numbering the seventh-floor landings.

Procedure

The Review proceeds by recension: each sitting re-reads the record of the sitting before it, and the record grows by accretion. Testimony is entered first, then contested, then entered again in the margin. A witness may revise a statement twice without penalty and a third time only with the panel's leave, which is granted at the panel's discretion and refused, according to the Office's own figures, in roughly one case in nine.

Findings are graded by weight of certainty rather than severity of incident, a distinction that has never been entirely understood outside the Office. A Review may conclude that a matter was certainly trivial or probably grave, but not both, and the grade is entered before the narrative is drafted so that the narrative may be composed to suit it. The practice is defended in Fifth Concordance, Annex 2, and would be abolished under Annex 6 of the same Concordance, which was ratified in the same session.

"The narrative is not the event. It is the event's respectful account of itself, delivered at leisure and under seal."

The 891-Sigma Question

The most contested matter in the modern history of Phase IV concerns its relationship to the Post-Incident Debriefing Log 891-Sigma, recovered during the Silent Stacks Excavation of 890-Σ. The Log presents a conservative reading of the Incident of the Wandering Addendum and recommends, among other measures, the installation of redundant spore-screening baffles following its review of narrative blight in active Floral-Fungal Logs.

Two schools dispute what this means. The Doctrine of Prior Record, held by the Office and most of the older Clerks, holds that the Log is a Phase IV Review Record in all but name, and that its recommendations bind subsequent Reviews as precedent. The opposing school, associated with the Convocation of Marginal Readers, argues that the Log is a debriefing instrument of the Clerks of the Spiral Body and therefore belongs to a different instrument entirely — that it may be cited in a Review but cannot be a Review, since it was compiled without a Writ and never sealed at an elevation. The Office has declined to resolve the question, noting in a circular of 891 that the Log performs the function whether or not it possesses the title, and that the title is a matter for archivists.

The Log's treatment of the Migrating Map as a parallel to unstable ontological feedback loops is cited by both schools, each reading the same passage to opposite effect. Protocol Alpha drew on the same passage when modelling its own handling of such loops, which has not settled the argument so much as lengthened it.

Records, Seals, and Costs

A convened Review produces one Review Record, entered in the Register of Reckonings and sealed three times: once at the close of testimony, once at the drafting of findings, and once when the record leaves the floor — the third seal being the only one the Office inspects. Records are deposited in the reading room of their floor and may not be removed. Custody passes to the floor, not to the Office, a division of authority that has caused at least four of the minor schisms recorded in the Annals of the Reading Rooms.

Recording costs are borne by the convening floor. Copyists are paid the standard rate per folio, and the cost of a Review is therefore, in practice, a function of how much its witnesses talked. The Review of the Twin Stacks Incident consumed four hundred and eleven folios and exhausted the floor's transcription allowance until the following spring; the panel's own estimate had been sixty. Panels are accordingly advised to sit mornings only. No panel has ever been disciplined for exceeding an estimate, and none has been reimbursed.
