Fuchsian-equivariant conformal nets: structure theory of 𝒞

[harryd-b]

Ledger: notes/QUESTIONS-2026-07-19.md §I item 10 (phases 99–100)

Develop the structure theory of the Fuchsian-equivariant conformal net 𝒞 — the "chartered field's" general program beyond the specific modular-flow questions:

• 𝒞's own structure theory: type, factoriality, the fate of the split property.
• The careful write-up of the vacuum-descent obstruction.
