However, I consider the Hα EW/PS_W dissipation timescale mismatch to be more load-bearing because it directly contradicts the qualitative claim that the model 'accounts for' spectroscopic variability — one of the three observable categories in the central claim. The density scaling is transparently reported and affects only normalization; the timescale mismatch persists even at maximum viscosity and represents a genuine model failure. The reader did note this as condition (3) in the rationale but did not elevate it to the primary concern. The CONDITIONAL verdict remains appropriate: the qualitative findings about injection geometry (localized, equatorial, mildly super-Keplerian) are robust and represent genuine progress, but the claim of reproducing spectroscopic behaviour is overstated given the factor-of-3 timescale discrepancy. The paper's own caveats (Sect. 5.2) are honest about this, which supports keeping the verdict at CONDITIONAL rather than REJECT. No ad hominem concerns; the authors are transparent about limitations. The SPH methodology is sound and builds on well-established code (Okazaki et al. 2002), and the HDUST radiative transfer is a standard tool in the field. The isothermal SPH assumption (Appendix C, Fig. C.1) is a secondary concern — it affects the viscosity through c_s and H, but the temperature deviations from the adopted 12 kK are modest in the dense inner disk where most dynamics occur.","tokens_in":30186,"tokens_out":4719,"duration_ms":162056,"concrete_test":"Re-run the preferred model (γ=1.05, R_inj=1.01 R_eq, Δφ=0.2 rad) with a radially increasing viscosity profile (e.g., α(r) = 1.0 for r < 2 R_eq, rising to α=1.0 at r > 3 R_eq following the suggestion in Sect. 4.1.3 referencing Ghoreyshi et al. 2021). Measure the PS_W decay slope at 200h and the Hα EW dissipation timescale. If the PS_W slope converges to within 30% of the observed 25 km/s/h without degrading the photometric build-up/dissipation slopes in Table 2, the constant-α=1.0 conclusion is superseded by a radially variable prescription.

The authors acknowledge this (Sect. 5.2) and suggest radially variable viscosity or radiative ablation (Kee et al. 2016) as remedies, but neither is included in the model. The photometric timescale matches well (Table 2), so the model can match photometry or spectroscopy but not both simultaneously. Since the Hα EW dissipation is a key diagnostic of disk physics and one of the three observable categories in the central claim, this is a genuine failure of the model to reproduce a claimed observable, not merely a normalization issue. The density scaling identified by the reader affects only the mass-loss rate amplitude (a quantitative concern), whereas the timescale mismatch affects the qualitative claim that the model accounts for the spectroscopic variability.

The qualitative result — that mildly super-Keplerian (γ=1.05), high-viscosity (α=1.0) ejections from a compact equatorial sector produce an asymmetric disk that circularizes in days and matches the observed flicker morphology — is solid and genuinely new. The parameter exploration is systematic, the physical reasoning is sound, and the code modifications to the Okazaki SPH code are clearly documented (Appendix A). The HDUST radiative transfer post-processing is real work and the synthetic observables are directly comparable to data. The paper also makes a clean argument against lever-arm injection (R_inj = 1.25 R_eq) based on the EWV/EWR frequency mismatch with the orbital frequency, which is a nice use of the Paper I observational constraint. Credit is due for the honest treatment of the isothermal assumption — Appendix C explicitly shows the HDUST temperature structure is far from isothermal, which weakens the hydrodynamic calculation but the authors flag it themselves rather than hiding it. The stress-test concern about the Hα EW and PS_W dissipation timescale mismatch lands. The simulated PS_W decay slope at 200h is 72 km/s/h versus the observed 25 km/s/h for f Car — a factor of three discrepancy, and the Hα EW also decays too slowly.

The scaling affects the mass-loss rate amplitude (the quoted ~10^-6 Msun/yr/str is fitted, not predicted), but the qualitative curve shapes are independent of it. The model selection by visual comparison rather than quantitative fitting is a weakness, though understandable given computational cost.

The authors systematically vary the geometry, rotation speed, viscosity, and injection radius of the ejected material, then post-process the hydrodynamic output with a radiative transfer code to generate synthetic observables that they compare to a well-documented flicker in the Be star f Car. The central claim is that a specific combination of conditions — material ejected at 1.05 times the Keplerian orbital speed (mildly super-Keplerian), high viscosity (alpha = 1.0), mass-loss rate of order 10^-6 solar masses per year per steradian, and injection from a narrow azimuthal sector (about 0.2 radians wide) very close to the stellar equator — produces synthetic light curves, H-alpha line profiles, line-asymmetry oscillations, and polarimetric signals that qualitatively match the observed flicker. Sub-Keplerian ejection fails to lift enough material into orbit; strongly super-Keplerian ejection produces disk behaviour inconsistent with observations; too-wide ejection angles erase the characteristic cyclic line asymmetries; and injection from above the stellar surface (a magnetic lever-arm scenario) produces oscillation frequencies too low to match the observed near-1:1 correlation with the orbital frequency at the equator.
