SHARED DIMENSIONLESS ROUTE COORDINATE
The coordinate is constructed from cumulative |Delta ln(a)|.
A: -1 at the outer contraction endpoint to 0 at termination.
B: -1 on the outer contraction branch, 0 at the exact bounce, +1 on the outer expansion branch.
C: 0 at the early small-a endpoint to +1 at the late endpoint.

NORMALIZED SIGNED FLOWS
Each raw signed flow uses its dataset-specific Q90 absolute scale:
normalized = raw / (Q90(|raw|) + |raw|)
The result is dimensionless, sign-preserving, and bounded within [-1,1].

ROUTE INTERPRETATION
A: terminal boundary approach
B: finite turning-surface routing
C: boundary-recession expansion

LIMITS
- The route coordinate is path intrinsic, not a final physical metric distance.
- boundary_margin_candidate remains provisional.
- Q90 normalization must remain fixed for matched reruns.
