Abstract
This paper details the characterization of 48 obsidian artifacts from Ein el-Jarba, an Early Chalcolithic site of the southern Levantine Wadi Rabah culture (6th millennium cal b.c.). By melding sourcing data from energy-dispersive X-ray fluorescence spectroscopy with the artifacts’ techno-typological specifics, we contrast Ein el-Jarba’s obsidian consumption practices with those of broadly contemporary and earlier communities in the context of the period’s emergent transregional character. The results attest to a major reconfiguration of long-term traditions, with well-known Cappadocian and Lake Van region source materials now supplemented by obsidian from the Caucasus, such material’s most southerly distribution. These diverse resources are believed to have circulated within the same exchange networks, mediated by communities of the Halaf culture to the north. Most of Ein el-Jarba’s obsidian was in the form of pressure blades from a common technical tradition, the implements likely procured ready-made from the well-connected site of Hagoshrim.

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
