Defects: what repair cannot flatten

A knot that will not untie. Repair drains the carrier quiet everywhere except one cycle, which stays lit no matter how long you wait.

The relation on screen

What survives full repair is what repair cannot reach, and topology decides that.

what to look for · Residual holonomy is quantised, so a defect either exists or it does not. There is no half a defect.

Consensus to physics

  1. 01repair removes disagreement that lives on seams
  2. 02an obstruction on one of the 19 independent cycles is not carried by any single seam
  3. 03no sequence of local moves removes it
  4. 04it persists as a localised object an observer can track

In standard physics

Topological solitons and vortex lines

Topological stability: the object survives because there is no continuous local path to the vacuum, the same reason a vortex or a monopole is stable.

boundary · A defect class is not a physical particle. The census is exploratory and non-evidential and makes no particle claim.
