The First Party on Counterpane's Membrane

In 2814 UCSD the Survey Corps puts a first party on one membrane of a neighbouring archecluster, reached by fold because the manifold is common and a fold does not care whose vocabulary the far end uses. No harmonic corridor opens to the party's drive lattice; its transits run fold-in and fold-out with no harmonic leg. The shelter is placed at the quietest gradient the party can locate, which is not a Lagrange point of anything.

For ninety days the party logs nothing anomalous, because nothing single-system is anomalous there. An atom is an atom; the spectrometer finds the handbook's lines; the calibrated second realises as it does at home. In the late autumn a routine correlation calibration run by Section Lead Syra, a Krenyi boundary analyst, returns a residual in the joint statistics of three independent sources, outside its budget. She applies every correction anyone can predict. The residual survives them. She files it as survives correction with the raw three-source statistics beneath it, and declines to countersign anything softer (Survives Correction (S01E00C05)).

Nothing is a finding yet. The value is carried home, as every value read on that bench has been carried since.

Canon facts:

• The first party reached the membrane in 2814 UCSD and logged nothing anomalous for its first ninety days; the residual surfaced in a routine correlation calibration in the late autumn.
• The residual is in the composition rule, the joint distribution of three or more independent quantum sources, and in nothing an instrument asked one question at a time can reach.
• Syra filed survives correction and the raw statistics, and no softer word; the party logged a discrepancy for a week and then stopped.
• The membrane was not yet registered as Counterpane. The first party reached it, read it and carried the reading home; acceptance, the registry name and the revisits are later entries.
