Physical derivatives of the native graph #
The graph, the integer covering, and the rounded carrier here are the actual ones of Definition 8.1 and equation (26). Bounds use actual Fréchet jets.
Four genuine polar charts with uniform finite-jet bounds #
The globally smooth functions constructed below equal the actual local polar inverse on neighborhoods of four compact sectors. Their global extensions are not asserted to be a global choice of angle.

The exact phase (26) has one fixed inverse-Q loss. The integer degree
of the slow factor may grow with the base profile class; it affects no power

Amplitude gain g, harmonic cutoff H, and slow degrees d,e affect only
the final constant. The phase class is supplied by liftedPhase_power_bound.
The four actual polar chart extensions supply one common constant for all normalized Cartesian phase derivatives; a sector always exists.
On a covering sector, the phase is the literal Cartesian realization
of (26), with R=√(x²+y²)/√Q and an actual local arctangent angle.
All polar branches share the same physical bound for the actual phase (26). No derivative hypothesis on the phase or on the native graph occurs: only the stripped amplitude and base profiles have class hypotheses.
