Inherited structure
Formal limits motivate humility but do not prove this scaffold complete.
D6 · boundary · [I]
Exit and nonclosure
The map marks its limit and cannot certify itself. D6 opens no positive freedom. It marks the point where the description stops, its unresolved questions remain visible, and the reader may put the map down.
Claim boundary
There is no additional μ-crossing after μ4, and D6 is not identical to D0. The return edge r6 means boundary-role resemblance only, not recurrence, identity, topology, or self-similarity.

r6 · [I] · non-causal interpretive edge
Interpretive return
D6 points back to D0 because both are selected limit markers. The relation preserves difference and adds no theorem.
Return to D0 as a reader, not as an identity →
