PLAN disposition

Fresh Grok PLAN approved frozen v3 without blockers on 2026-10-12 at 22:39:52Z. Exact verdict SHA256 c810226e7b5865b57b3d0bf0b5f7d916b3b0fb6fb620298a0daa0723fb77ade1. Root read the verdict and authorized the exact production scope. The reviewed PLAN and capsule remain unchanged. Implementation uses overflow-safe div_ceil, pops before child pushes, and documents admitted usize width as geometry only. A finite isolated no_std binary link probe will report actual dependency/link limits; no substitute allocator or 32-bit runtime pass is inferred.
