reviewer:will-blair
Noise and retrieval degeneracies limit JWST to detecting only the most robust biosignature pairs (e.g., O2 + O3 at ppb levels) on the nearest Earth-analogs; marginal detections of single gases (DMS, N2O) lack sufficient statistical support for biosignature claims

vf_5aaa17390be98053Hycean habitability (speculative) predicts strong sulfur biosignatures, but K2-18b's lack of DMS confirmation undermines the hycean-as-common-biosignature hypothesis; alternative explanations (abiotic pathways or non-habitable conditions) are equally viable
