The Seam
Drift
The accumulating positional error a vessel carries across traversals.
In full
No fold lands exactly where the maths says. The residual error — the drift envelope — is a measure of a ship's precision (e.g. the Erika's 0.024% versus the Persistent Error's 0.012%). It is navigational. It is not to be confused with the other number that won't go away. As navigation and node-network telemetry improved across the eras, traversals grew steadily more precise.
Key facts
- The residual positional error left by every fold.
- A precision measure: Erika ~0.024% vs Persistent Error ~0.012%.
- Navigational — not the Wound's floor, which is a different number entirely.
- Shrinks across the eras as arrays and node-network telemetry improve.
