Abstract This record contains the complete empirical dataset, raw benchmark files, high-resolution vector figures, and the scientific PDF report for the release of QECTOR Decoder v3 (v0.6.8) by Guillaume Lessard. The primary objective of this benchmarking campaign was to evaluate the algorithmic accuracy, decoding throughput, and memory scaling of Minimum Weight Perfect Matching (MWPM) and Union-Find (UF) quantum error correction decoders operating in a resource-constrained edge environment. All empirical tests were conducted on an edge machine featuring an HP Dual-Core x86_64 CPU, 3.1 GB RAM, and no local hard drive (booted live from an AntiX Linux USB drive without swap memory). Key Benchmark Findings Exact Mathematical Parity: The compiled C++/Rust qector_blossom_weighted decoder achieves exact parity in Logical Error Rate (LER) and failure counts when compared against PyMatching (v2.4.0) across all tested physical noise rates ($p \in [0.002, 0.008]$) and distances $d \in \{3, 5, 7, 9\}$. 100% Algorithmic Faithfulness: All CPU decoders (FastUnionFind, UnionFind, Blossom, SparseBlossom, BatchDecoder, and CPUBatchDecoder) achieved 100% parity verification ($H \cdot \hat{e} \pmod 2 = s$) across odd distances $d \in [3, 19]$. Topological Speed Advantage at High Distance: While exact Blossom MWPM scales with graph complexity ($1.77 \times 10^4$ shots/s at $d=9$), qector_union_find maintains $1.62 \times 10^5$ shots/s at $d=9$ ($9.1\times$ faster), demonstrating the speed utility of topological decoders on low-power host CPUs.
