The most load-bearing defect is the gap between that universal claim and the single-object evidence. The FZ Tau example, even if fully correct, only shows that one disk's MIRI CO spectrum is blended and degenerate; it does not show that every JWST program has this requirement. The model/calibration caveat noted by the reader is real and should be fixed, but it attacks the illustrative demonstration, not the universal claim; a calibration offset could change the FZ Tau temperatures while leaving the \"all programs need CO kinematics\" assertion untouched. Conversely, a census showing many JWST disk programs do not depend on resolved CO kinematics directly falsifies the universal claim. The portal itself is live and code is public, so the infrastructure claims deserve credit; the fix is to scope the science claim and, incidentally, to report uncertainties for the fits.

The paper's evidence is one demonstration on FZ Tau (Fig. 6): a two-component CO line profile and a population diagram fit with a single-temperature slab model. A single object cannot establish \"all programs,\" and the demonstration does not even show that MIRI spectra alone cannot recognize small inner disk cavities; it shows a degeneracy in one object's CO excitation. Many JWST disk programs address diagnostics where resolved CO kinematics is not a stated requirement (e.g., ice absorption, continuum, water inventories, outer-disk chemistry, or molecular column densities from unresolved bands). Without a systematic enumeration of Cycle 1 and later program goals, the universal claim is an overgeneralization. This is distinct from the calibration/modeling weakness in Fig. 6, which would weaken the illustrative value but not directly test the universality statement. The infrastructure part of the paper is independently supported by the live portal and public code; the concern is specifically the scope of the science-value claim.","agreement_with_reader":"partial"},"referee_report":{"model":"deepseek-v4-flash","summary":"The paper describes the design, implementation, and public release of SpExoDisks, a web portal and database for infrared spectra of protoplanetary disks.

The roadmap for building a specialty astronomy database is the actual new thing here, and it's useful beyond the disk community.\n\nThe science demonstration (FZ Tau, iSHELL + MIRI-MRS) is a good idea but the paper overreaches in one place. The §6 sentence claiming 'all JWST disk programs in Cycle 1 and beyond will need to use high-resolution ground-based CO spectra' is a universal assertion built on a single object. No survey of JWST program goals is provided, and many programs target ice absorption, continuum, water inventories, or other diagnostics where resolved CO kinematics is not the stated requirement. Scale it back to 'many' or 'disk kinematics programs.' The fits also lack error bars and the relative flux calibration between the two instruments is untested; those are real but secondary weaknesses that dent the illustration, not the infrastructure case. The missing Gaia citation is a trivial mechanical fix.\n\nThe reader's circularity concern doesn't land. The slab-model fits are honest fits to published spectra, not predictions dressed up as independent validation, and using your own portal to demonstrate utility is legitimate.\n\nBottom line: a solid infrastructure paper with a soft science paragraph. It deserves a serious referee. I'd take it conditionally: temper the universal claim, add uncertainties or at least a calibration caveat, fix the citation.

Its more consequential claim is scientific: mid-infrared spectra of planet-forming disks taken by JWST are degenerate on their own, because line blending and limited spectral coverage cause simple fits to overestimate the gas temperature. The paper demonstrates, on the disk of FZ Tau, that adding high-resolution ground-based CO spectra from the same portal breaks the degeneracy, revealing two gas components with different temperatures and column densities. If the authors are right, SpExoDisks becomes a load-bearing resource for interpreting JWST disk programs, and the design roadmap it documents gives other subfields a template for building similar portals.","feed_headline":"Ground-based CO spectra break the deadlock in JWST disk data","feed_subtitle":"Combining iSHELL and MIRI-MRS views of FZ Tau exposes two gas components that MIRI alone blends into one fit.","key_machinery":"The load-bearing mechanism on the data side is the SpExoDisks processing pipeline: raw spectra from eight instruments are read in, verified, and standardized; star names are resolved through an external name-resolution service into a single star ID; spectra are registered under human-readable spectrum IDs; and the curated data is served through a REST API backed by MySQL tables in third normal form. On the science side, the argument runs through the population (rotation) diagram of CO line fluxes plotted against upper-level energy $E_u$, where a straight-line slope encodes gas temperature and curvature encodes column density. Fitting the FZ Tau CO lines with a plane-parallel single-temperature slab model, with temperature $T$ and column density $N$ as free parameters, separates the narrow component ($T \\approx 1180$ K, $N \\approx 3\\times10^{17}$ cm${}^{-2}$) from the broad component ($T \\approx 1420$ K, $N \\approx 10^{18}$ cm${}^{-2}$); the same diagram made from MIRI-MRS data alone flattens because of line blending and missing low-$J$ coverage, forcing an overestimated single temperature of about 2460 K and a much lower column density.","core_discovery":"The authors' central claim is that a community-scoped database portal uniting infrared spectra from many instruments can reveal structure in planet-forming disks that no single dataset provides, and that this combination is now required to interpret JWST observations.

Fitting the MIRI data alone, by contrast, blends the components and covers only the high-$J$ part of the band, yielding a degenerate single temperature of about 2460 K and a much lower column density.
