pydynamicestimator.tests.test_compute_i_full

Numerical validation of compute_i_full post-processing against CasADi branch_current_fun.

Compares the new vectorized NumPy i_full computation against the original per-step CasADi build_branch_current_fun approach across multiple scenarios.

All tests use frozen fixtures under tests/fixtures/ rather than the shared pydynamicestimator/systems/ workspace, so interactive edits to the demo systems cannot silently change test behavior. See tests/fixtures/README.md.

coi mode, incl_lim=True.

COI frequency deviates from 1.0 pu during transients, so the omega=1.0 approximation in build_y() causes a small error vs the frequency-aware CasADi function. Same root cause as the dist mode discrepancy.

Uses the LOAD-step fixture so the disturbance is pinned.
