Abstract
The article by Wright et al. ( 1 ) is the latest in a series of papers suggesting that Mars' inventory of liquid water was sequestered into the crust, rather than entirely lost to space ( 2 , 3 ).The authors constrain the presence of water in the mid crust (~11.5 to 20 km depth) by comparing bulk-rock geophysical data obtained from the InSight lander with a petrophysical model using a linear combination of putative igneous compositions (mafic basalt to felsic anorthosite).Using these parameters, the "best fit" to the InSight data is a water saturated (γ w = 100%) mid-crust.Although performing an inversion to determine physical properties from seismic data is an appropriate approach, the geological assumptions upon which it is based are less sound.Martian areotherms indicate a minimum increase in temperature with depth of 12 °C/km, but potentially as high as 20 °C/km ( 4 ).A median value of 16 °C/km equates to midcrustal temperatures of ~180 to 320 °C, placing the equilibrated conditions firmly within the metamorphic domain ( Fig. 1 ).Terrestrial field studies ( 5 ), laboratory analyses ( 6 ), and petrological modeling ( 2 , 4 ) show that hydrated igneous

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
