LinearOperator: Rectangular-capable narrow waist shared by stored and matrix-free maps.
ShiftedLinearSolver: Reusable factorization of (A - shift I).
TimeDependentOperator: Narrow waist for operators whose action depends explicitly on time.

anticommutator
apply_sector_shift: Apply parsed terms directly between sectors without materializing a matrix.
bra_ket_transitions: Raw local transition table, including branching callbacks and fermionic signs.
