Coin from the Ptolemaic Kingdom of Egypt; Ptolemy IV Philopator. On the obverse, diademed head of Zeus-Ammon, with ram's horn and tainia, facing right. On the reverse, twin eagles with their wings closed, standing left on thunderbolt, which symbolise Zeus’ divine power; cornucopiae to the left. The inscription reads ΠTOΛEMAIOY BAΣIΛEΩΣ (“King Ptolemy”). Border of dots on the reverse. Mint, Alexandria, Egypt, Cornucopia Series 5. Cental dimples on both sides. Early coins often have punch holes suggesting they were repeatedly tested to determine their true composition or because of the technical manufacture as they were part of the flan preparation. Date: 221–205 BC.

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.
