math, symbolic & geometry (the everyday-math tier)

namewhat it does
slidesafe numeric expression evaluator: arithmetic/trig/log, vectors, statistics, and science constants; optional vars, so load-bearing arithmetic is validated compute, not inline numpy: a slide rule with a contract
slatesymbolic CAS (sympy): algebra, calculus, solve, roots, series/limits, and vector calculus (gradient/jacobian/hessian/laplacian): the full CAS scribe stopped short of
protractorfirst-class geometry with diagnostics and geometric invariants, not just area formulas

Six of these are also forged on the GPU tier under the same names and the same gates: compass, tuningfork, comb, coil, sextant, and abacus. Same call, hardened CUDA build.
