What this shows
A historical scope boundary in the public map language: where the old Atlas sequence ended and protected research began.
The outer research boundary preserved from the historical Cosmography Atlas lineage.
The first revival intentionally publishes no candidate map here. Historical public graphics containing candidate-like markers remain preserved in repository history but are outside the live allowlist.
In the 2025 Atlas, X-Domain named an outer conceptual research region beyond the inner and giant-planet map sequence. The current public surface keeps only that historical boundary meaning.
A historical scope boundary in the public map language: where the old Atlas sequence ended and protected research began.
The boundary is not evidence for an unknown object, a hidden result, a detection model, a physical shell or a forecast.
Provenance: Φ-Cosmography public Atlas lineage · boundary semantics retained; candidate-style historical graphics excluded from the first live revival.
