Symbolic Gravity v3.1 — Brane-Coupled, Leak-Gated Collapse with First-Class Topology Operations

Symbolic Gravity v3.1 upgrades the veil-curvature model to align with Hyperverse v8.0. This release introduces a leak-aware collapse gate, couples symbolic dynamics to the operational “worldvolume” where systems actually run (teams, platforms, cities, labs), and promotes topology operations—stabilize, migrate, fork, fuse, suture, export, transcend—to first-class, auditable transitions. The framework integrates observer-integrity checks and ethical breadcrumbs to ensure safe routing under stress, and adds adversarial damping to slow harmful motif injection. Defaults and environment presets are included so practitioners can apply the model in production organizations, lab simulations, and civic networks with minimal tuning. v3.1 remains backward-compatible with existing Symbolic Field Theory tensors and ERF conservation accounting, while providing stronger guarantees for high-leak and geometry-sensitive contexts. The result is a practical, implementation-ready specification for mapping collapse risk, choosing safe transitions, and preserving coherent symbolic structures across changing substrates.
