Papers — 432 placement proofs

432 placement proofs — 108 torus coordinates × 4 homology generators (H₁(Σ₂) = ℤ⁴), each a bidirectional genus-2 fold, compute-only via corpusParams; corpus root 268169f7-fdf0-8fa9-a247-de7f822be194.

Double torus corpus routing: the genus-2 machine computes the 1024-leaf Merkle tree; corpusParams(kind, id) resolves any leaf at call time. The WHOLE corpus is compute-only, and compute-only is NOT purge: every combination FILLS computationally on demand (paperParamsById generates each paper monograph), so the meaning is computed, never absent — only the empty static shells (measured 0 text chars each, 252 MB) are not built. Served static mass = the theorem registry and its rosetta derivatives.
