Abstract
This beautifully carved object is a placenta bowl, or “ipu whenua,” carved circa 1900 by an unknown artist from the Rotorua region of New Zealand. It was created from a native Matai hardwood and inset with abalone shell. The bowl is intricately carved with overlapping animals and ancestral figures termed Tiki. The Tiki represent strength, communication and fertility. These carvings represent legends passed through generations of Maori people at least since New Zealand was discovered by Polynesian people over 2000 years ago and likely long into the distant past. The very close relationship that the Maori have with their land is clear: the word “whenua” refers to both the placenta and the land in Maori culture. After delivery, the placenta is placed into the bowl, taken to a site important to the family, often ancestral land, and ceremonially buried. This act creates and represents a deep and abiding relationship and responsibility with and toward the landscape, and reinforces ancestral ties and responsibilities to the child’s “iwi” or clan. The ritual has its origins in the proverb “He taonga no te whenua, me hoki ano ki te whenua,” which means, “what is given by the land should return to the land.” The practice ebbed in the past century, but appears to be enjoying a renaissance as the Maori embrace their cultural heritage. It gives us pause to reflect on what we do with the placenta in modern North American culture.

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.
