Post-merge engineering evidence for the bounded-reduction cutover is recorded alongside the shared fold authority: #8 (comment) . On the documented two-item Float32 witness, bounded sum infers a concrete isbits evaluator (234 optimized typed-IR statements), uses the existing direct Unique path (2 complete provider launches), has 1,536 warm host-allocated bytes, and records zero warm Julia compilation/recompilation. The generic rejecting fold remains 5 launches as required by its failure semantics. These are focused observations, not a general throughput or GPU-latency claim. |

Adds deterministic bounded-view sum, extrema, mean, and geometric mean on the existing BoundedFold authority. Preserves duplicate and absence semantics, explicit primitive result types, transaction rejection, and the sole CPU/Metal KernelAbstractions path. Updates the package to 0.2.0-rc2 with release notes and documentation.\n\nValidation: focused CPU reductions 157/157; LocalMath documentation and doctests pass; focused real-Metal authoring 31/31 on Julia 1.12.6.
