Unidentified Combatant — Sensor Reconstruction

The first sustained sensor return on the hostile at Junction 44-K — six seconds of usable data, and a reconstruction that is mostly the shape of what the instruments could not resolve. Filed because protocol requires a file, not because the file answers anything.

CONTACT TVA-S/2192 · JUNCTION 44-K ISCA-TI · CONFIDENCE: LOW

The Resolute held contact with the object for the length of one engagement and no longer. What follows is reconstructed from 6.2 seconds of usable sensor return, taken across the array-fire exchange on Day 40. There was no second pass. There was no cooperative emission. Most of this sheet is the record of an instrument reaching for a reading and closing on nothing.

The Sensor Section files it because the protocol requires a contact file. The protocol does not require the file to be useful.

Geometry & Hull

FieldReadingConfidence
Overall length180–260 m (envelope only)Low
Hull formAsymmetric; no bilateral plane resolvedLow
Section countUNDETERMINED
SurfaceNon-returning across most of the sweep; absorbs more than it reflectsLow
Registry / markingsNONE DETECTED

The hull did not give the array a clean silhouette at any point in the exchange. Where a return was expected, the instrument logged absence. Whether that absence is shaping, coating, or an artefact of the geometry, the section cannot say.

Note (Lindqvist, science relay): “We are not failing to read it. It is arranged so that there is nothing to read. Those are different things, and the second one should worry us more.”

Propulsion

FieldReadingConfidence
Drive typeUNDETERMINED
Manoeuvre profileCame about faster than its mass should allowLow
Exhaust / plumeNONE OBSERVED
FTL signatureNONE — appears to traverse by junction onlyModerate

No drive plume was recorded at any heading. The object changed bearing without a visible reaction mass and without the thermal bloom the section would expect from a vessel of the reconstructed envelope. The absence is consistent. It is not explained.

Armament

The one section of this sheet with data, because it is the section the Resolute met directly.

  • Primary: kinetic; rail-accelerated penetrators, beamed flat and fast. Round signature does not match any ISCA or SNG pattern on file.
  • Magazine doctrine: patterned fire — bursts, not sustained. Sparse, deliberate, as if rounds are not cheap to it.
  • Targeting: locked the Resolute without an emission the array could trace. We did not see it look at us.

This is the part of the contact the crew did not have to reconstruct. They were inside it.

Emissions

FieldReadingConfidence
Active sensor emissionNONE DETECTED
ThermalBelow floor; colder than its own exhaust should permitLow
Internal signalOne directed pulse, lower-band of the harmonic-stack spectrumModerate

A single directed signal pulse was logged late in the exchange, beamed off-axis into the junction’s deep margin — not at the Resolute. Lower-band; light-speed; gone in under a second. The section’s reading: it was not talking to us. It was talking to something else out there.

That means there is a second one.

Provenance Flag

One low-confidence inference, recorded and explicitly not relied upon: elements of the round signature and the lower-band pulse sit close to Tarvan-design-lineage hardware on file from the Drift-era contact records. The match is partial. It may mean the object carries diverted hardware. It may mean the instrument is pattern-matching noise to the only catalogue it has. The section will not stake a classification on it, and neither should the reader of this sheet.

Assessment

Nothing on this sheet rises to a species designation, a vessel class, or an intent. The contact is logged as TVA-S/2192 — a tracking label, not a name.

Recommendation: Take the object’s protocol-refusal at face value. Do not pursue. Do not escalate. Hold the chair’s reading — that it was not after the Resolute, but guarding something the Resolute came too near. The institutional reading will take years. The crew calls it the Splinter in the meantime, because a crew needs a word, and UNDETERMINED is not one.
