Summary

Initial li-std-physics* package family, expanded li-std-math, runtime transcendentals, Tier-2 benchmark kernels, and numerical-policy spec.

Packages

  • li-std-math — spatial types and ops
  • li-std-numerics — integrators, three-body reference
  • li-std-physics-core — PhysicsProfile, NumericalTargets
  • li-std-physics-rigid, -runtime, -particles, -fluids, -weather, -aero, -chem, -em, -quantum, -relativity, -hep

Compiler / runtime

  • li_rt_sin, li_rt_cos, li_rt_atan2, li_rt_exp, li_rt_log

Docs / agents

  • docs/physics/overview.md, numerical-policy.md
  • docs/superpowers/specs/2026-05-16-li-physics-numerical-policy.md
  • Skill: .cursor/skills/research-li-numerics

Benchmarks

New under benchmarks/tier2_physics/: rigid_body_stack, three_body_pure, wind_field_bc, combustion_passive, orbit_two_body, fdtd_waveguide_2d, schrodinger_1d_barrier

Verification

  • lic build on packages when LLVM 22 toolchain available
  • ./benchmarks/harness/bench.py --tier 2 --ci after compiler build
