Audit review
The candidate solution reproduces the paper’s resonance-manifold construction and the three transition mechanisms (MM0, SM, MMπ), and derives the same critical relations for ξs(Ω), fs(Ω), fm,0(Ω|ξ̃), fm,π(Ω|ξ̃), and the coexistence frequency Ω*. Any differences are purely notational or organizational (e.g., describing iso-energy envelopes and frequency-response slices), not substantive.
Referee report (LaTeX)
\textbf{Recommendation:} minor revisions
\textbf{Journal Tier:} specialist/solid
\textbf{Justification:}
The work gives a precise RM/LPT-based account of transient mechanisms in an HCVI oscillator, with explicit, verifiable thresholds and envelopes. It extends known methodology to an impactful (pun intended) hybrid nonlinearity and buttresses claims with numerics. Minor editorial clarifications (assumptions, notation, branch usage) would make it even clearer.
