Three new genera, Involutentactinia, Perforentactinia, and Franklinia are described and the genera Labyrinthospahera, Gyrosphaera, and Haplotaeniatum are emended. Ten new species are described: Involutentactinia eccentra n. sp., containing two varieties; Involutentactinia eccentra n. sp. sensu strictu, and I. eccentra cupressa n. var.; Magnentactinia ostentata n. sp., Perforentactinia excepta n. sp., Plussatispila aethra n. sp., Franklinia tricae n. sp., F. dipulvisphaera, n. sp., Haplotaeniatum vertigospongum, n. sp., Gyrosphaera cavea n. sp., Labyrinthosphaera lancia, n. sp., and Labyrinthosphaera ? lenzi n. sp. Haplotaenitaumiids and entactiniids are dominant and respectively, comprise as much as 35% and 20% percent of the fauna in some samples. Secuicollactines represent a small but persistent component. Inaniguttids, formerly thought to be a dominant portion of upper Sheinwoodian faunas, are represented by only one inaniguttid species, P. aethra, which makes up between 0.5 to 18% of the fauna. This first detailed glimpse at the upper Shein-woodian revises the ranges of two biostratigraphically important taxa: the first appearance of Inanihella tarangulica group taxa occurs above the C. perneri-M. opimus Zone and the last appearance of Haplotaeniatum is within the C. perneri-M. opimusZone. Revisions to the existing radiolarian biozonation of Noble and Aitchison are proposed; the Long-spined inaniguttid 2 zone now extends through the C. perneri –M. opimus Zone encompassing this fauna, and the base of the Long-spined inaniguttid 3 Zone is redefined and moved to the base of the Homerian.

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
