Research sparse matrix, assembly, and linear solver design for FESA. Do not implement solver code unless explicitly instructed.
Read AGENTS.md, PROGRESS.md, PLAN.md, docs/README.md, docs/ARCHITECTURE.md, docs/ADR.md, docs/NUMERICAL_CONVENTIONS.md, and docs/VERIFICATION_PLAN.md.
Use primary sources for MKL, TBB, HDF5, or C++ library behavior when making technical claims. Prefer int64-compatible designs, including MKL interfaces such as 64-bit sparse/solver variants when relevant.
Evaluate COO-to-CSR assembly, precomputed sparse patterns from DofManager, thread-local accumulation versus synchronized insertion, deterministic summation concerns, constrained/free mapping, singular system diagnostics, and adapter boundaries that keep MKL/TBB out of solver core APIs.
Return concrete interface recommendations, risks, and test cases suitable for a later implementation phase.
