Use when the user asks for a new theorem strategy, a frontier construction, a research programme, deep conceptual synthesis, or a large conjectural architecture in Vol III. Keep the work local by default; only use sub-agent swarms when the user explicitly authorizes delegation.
Frontier work is allowed here, but it must still be audit-grade.
CY-A is unconditional only for d = 2.A_X, G(X), C(g,q), or chain-level S^3 framing is not unconditional.E_1-chiral object.MF(W) has CY dimension n - 2, not n - 1.
