Abstract
Recent work in ecohydrology has shown that in some forested watershed systems, streams and trees appear to return different pools of water to the hydrosphere. Thus far, evidence for this has come exclusively from wet Mediterranean climates. This short opinion article outlines the hypothesis and a research agenda for future work. The most pressing issue is the need to gather more data points whereby dual isotope‐based studies in forested catchments compare samples of plant water and tightly bound soil water as well as mobile waters (soil, groundwater, and streamflow) in the catchment. New work is needed to test the hypothesis across different climates and vegetation regimes, especially places that contrast with the Mediterranean climates and forest types where two water worlds have been found. These include, but are not restricted to humid areas where plant water use and precipitation input are in phase, wetter zones where seasonality of precipitation is low, and drier zones where water stress is higher. Of equal importance to these basic research issues are the practical issues surrounding the sampling methods of plant and soil waters. Studies are needed to compare extraction techniques for low and high mobility soil waters and to understand the effect of sampling protocol on water isotope composition. Once these issues are resolved, high frequency sampling of soil and xylem waters will be especially instructive in development of mechanistic models of ecohydrological interaction—and an explanation for the hypothesis that is still wanting.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
