#On the Name and the Permission
The phrase "free choirs" is a plural and should stay one. The Shrine-Deck professional record lists them among the rivals of the Shrine-Deck Crew, next to underworld artillery smugglers and rival arsenals, and glosses them in four words: unsanctioned cadence cults. That is the whole general entry. No founder is recorded, no rule, no house, no hymnal, no roll of members and no year of origin. Anyone who tells you the free choirs are a movement with a mother-chapter and a creed is selling you a pamphlet, and the Bureau of Purity will want to know where it was printed.
What the record supports is narrower and worse. Where singers already govern the timing of guns, some of them have gathered without licence, and at least one such gathering claimed that the singer's body could do what only a seal may do. That gathering was in Cologne. It is the only free choir whose teaching survives in deposition, so this survey uses it as the documented case and does not make it the pattern for every other.
#On the Measure and the Seal
Licensed procedure first. Without it the heresy cannot be understood, only deplored, and deploring is cheap.
A shrine-platform fires in six movements. The Ward-Chalker renews the chalk ring and sets the relic pins. The metronome bell is tuned so that choir and recoil rigs keep one interval. Powder and shot are loaded by hymn-bar. The volley lands on the sanctioned toll. The shot is logged at once with its type, time, purpose and authorizing seal. Then the barrel is swabbed, and anything irregular is confessed. Choir Runners carry the cue-slate. Cadence Callers stand between choir and battery and turn the one into the other. The Ordnance Deacon holds the wax.
The singers' power is real. Since the Cadence Reforms a choir can ground a battery by losing the measure, and gunners have hated them for it ever since. A singer decides when. The seal decides whether. The authorization column in the shot-ledger exists to keep those two questions in separate hands, because the hand that keeps time under fire is the hand least able to deliberate about targets.
The crews put it more briefly: wax first, wrath second. Two acts are unforgivable on a licensed deck, firing without an authorizing seal and writing the log after the fact. The penalty for "unsealed discharge" is immurement. The Church does not wall people up over a matter of etiquette.
#On the Saint Claimed
Saint Orla the Brass-Throated is the recognized patron of Shrine-Deck crews, Cadence Callers, Choir Runners and fire-harmed singers. The Bureau of Rites places her defining act in a hymn-gallery fire aboard a Danube shrine-barge, c. A.S. 130 (c. 1840 CE). The hagiographic account has her at the conductor's rail after the metronome bell fouled, holding the interval through the Canticle of Measured Fire while the gallery burned around her. Cathedral reckoning gives forty minutes. The Bureau of Bells disputes the tonal claims, the Bureau of Engineering the behaviour of the fire, the Bureau of War the casualty table. The guns fired true. Nobody disputes that part, because the convoy arrived.
The decks read her plainly. When the instrument failed, a person kept the measure. That is the whole of her precedent, and it concerns timing. The hagiography has no Ordnance Deacon dying at her feet. No account says she ordered a single shot that had not already been sealed.
The Cologne cell read her differently. Its theology rests on the injured throat. It held that a voice which bleeds while giving the order has been tested past anything wax can certify, and that the test confers the authority. Everything procedural in that reading is backwards. The licensed record treats blood in a singer's mouth as a warning. If a singer coughs blood, shorten the sequence. Cue drift kills. Coughing blood is on the inspectors' list of what "bad" looks like, together with cue disputes and smudged chalk. The decks shorten the hymn to protect the singer and the guns. The cell made the same symptom a credential.
Training icons show Orla standing untouched amid stylised flame, face serene, pitch-pipe shining.
Correction: recovery notes describe burns over most of the body, inhalation damage, melted collar brass and both hands contracted around the rail. Any argument from her injuries must be made against the injured saint, not the painted one, and the injured saint's record contains no seal she set aside.
Her brass pitch-pipe is attributed to her and kept at the Cathedral Arsenal Office in Strasbourg. Examiners report it is warm. Warmth in a relic case proves warmth and nothing more. The Cologne cell may have invoked it, but its whistles were never pieces of it, and the pipe has not left Strasbourg.
#On the Cologne Deposition
The deposition is short, and I have not lengthened it. It records the claim in the cell's own wording, the objects recovered, one question and the disposition. It does not say how many people were taken, how the room was entered, whether the cell ever fired anything, or when. Purity's clerks write as if every reader already knew the date. I do not.
The claim: Orla authorises firing without an Ordnance Deacon's seal if the singer's throat bleeds during the order. The phrase the cell used was shorter, and good enough to set to music, which is precisely what Purity feared:
"The bleeding throat outranks the seal."
Recovered: seven brass whistles, one altered metronome bell, two ledgers with blank authorization columns, and an Orla icon with the eyes scratched out.
Each object deserves a sentence, and none deserves more. Seven whistles prove seven whistles. They do not give a membership count, since one throat can own several instruments and a whole choir can share one. The bell was altered. The deposition does not say how or to what end, and I will not say it for them. The ledgers are the damning articles. Those were columns ruled for authority and left empty on purpose. Blank columns show a habit, or an intention. They do not show a particular volley or a body count. The icon belongs to the cell, or to someone in the room who stopped agreeing with it. The record does not say which hand held the nail.
BUREAU OF PURITY — FREE CHOIR DEPOSITION, COLOGNE CELL Final question to condemned conductor: "Who held the measure?" Answer: ███████████████████████ Disposition: all whistles melted; bell retained; icon sealed facing wall.
The conductor is recorded as condemned. The answer is not recorded at all, and it will stay unrecorded here. The ledgers' disposition is not given either. Somewhere an archive holds, or burned, two books full of authority nobody granted.
#On the Objections
The professional objection and the institutional one are separate. People who blur them are usually defending the second while pretending to defend the first.
The professional objection concerns time and sound. A singer who is bleeding is a singer about to drift, and the deck fears drift more than fire. A gun discharged between tolls makes the deck go hollow, "as if it is being answered," in the crews' phrase. The professional record lists demon resonance in sustained screams among its failure modes, and the crews do not hum between tolls. Nothing in the deposition shows that the Cologne cell summoned anything or fired a single round. The danger is that its doctrine, put into practice, would make every hemorrhage a firing order at the moment a singer is least able to keep the count.
The institutional objection is about the seal, and here I am obliged to be honest, which I find irritating. Licensed decks keep ghost entries to hide misfires. Licensed callers take "extra wax" to stretch a measure for an unsanctioned target. Licensed crews pass stolen shells off as salutes and fire into crowds "by seal." The largest bribes on the river are authorizing seals. The seal is no proof of righteousness. It proves that someone with a name and an office will answer for the shot. The Cologne doctrine moved that answer from an office to a wound, and a wound cannot be audited, fined or grounded. A condemned conductor can be asked who held the measure, and the record will show what came back.
#On the Present Holding
This is a classification survey, and the record supports only so much. The free choirs are unsanctioned cadence cults, rivals to the licensed decks, of unknown number and extent. The Cologne cell taught that a bleeding throat outranks the seal. Purity suppressed it, condemned its conductor and disposed of its objects as stated. Neither the founding of the free choirs nor the date of the Cologne suppression is recorded. This survey does not claim that other cells are extinct, and it does not claim that any are active.
The unsanctioned deck choirs selling Orla whistles at river-locks are a separate nuisance, filed separately. So are the counterfeit relic dealers. Merging them into one conspiracy would flatter all three.
The Bureau of Doctrine holds the teaching, not the singers, to be the heresy. A singer may keep the measure until the deck burns under them, and the decks will light candles for her. She may not grant a discharge.
