Season 3 · Episode 1

Principal Tissadelle Shepherd works a backlog of archived Hegemony survey telemetry through the Survey Corps' standing data-exchange with the Cerebraun Hegemony — and finds, in a signal filed as noise for centuries, the one thing the classifiers were never built to listen for.

• S03E01C01 Filed Under NoiseHalyx Relay Station, Halyx System — Survey Corps liaison archivePrincipal Tissadelle Shepherd runs a routine archive backlog and hears structure in an EM pulse that centuries of Hegemony classifiers filed as noise. Getting the reclassification approved is the harder problem.
• S03E01C02 Independent VerificationHalyx Relay Station, Halyx System — Survey Corps Review ChamberThe reclassification survives review, but Principal Shepherd learns what it costs to be believed on the strength of an ear nobody trained her to use — and Sohrel learns what it costs to have authorised her being heard at all.
• S03E01C03 What Meridian AskedHalyx Relay Station, Halyx System — Survey Corps liaison archive; a sealed consultation channel to the Long Shelf reef-cityA fifth request to consult Meridian about the Sentinel arrives — not from inside the Hegemony this time, but from the reef-cities themselves, on their own terms. Sohrel spends what four quieter declinations had been saving, and Shepherd learns what her own finding costs when it stops being only hers to file.
