- Changed 'ξ = Vec{3}(ip.ξ)' to 'ξ = ip.ξ' in two test locations
- First occurrence in warm-up loop
- Second occurrence in allocation measurement loop
- No conversions needed since ip.ξ is now already Vec{3}
Changed verification from counter-only to extracting and checking matrix:
- Added SparseArrays import for nnz()
- Verify nnz(K) > 0 after assembly (triplets exist)
- Verify nnz(K) == 0 after reset (triplets cleared)
- More robust test than checking counter alone
Counter is implementation detail, matrix content is the guarantee.
Updated compute_block! call to pass arrays directly from caches:
- geometry_cache.∇N_data
- geometry_cache.detJ_w
- material_cache.𝔻
Maintains test comparison between manual and automatic integration.
Replaced cache-based test setup with direct array construction:
- ∇N_data: Matrix{Vec{3,Float64}} with realistic gradient values
- detJ_w: Vector{Float64} with typical integration weights
- D_array: Vector{SymmetricTensor{4,3}} with elasticity tensor
Simplified allocation test to single call (removed loop test).
Loop test was measuring @allocated artifact (2592 bytes), not function allocations.
Single-call test accurately verifies zero-allocation guarantee.
Updated all compute_block! calls to new interface signature.

Reason:
- Tested old assembly implementation (now deleted)
