Abstract
The Second Planck Catalogue of Compact Sources is a list of discrete \nobjects detected in single-frequency maps from the full duration of the \nPlanck mission and supersedes previous versions. It consists of compact \nsources, both Galactic and extragalactic, detected over the entire sky. \nCompact sources detected in the lower frequency channels are assigned to \nthe PCCS2, while at higher frequencies they are assigned to one of two \nsubcatalogues, the PCCS2 or PCCS2E, depending on their location on the \nsky. The first of these (PCCS2) covers most of the sky and allows the \nuser to produce subsamples at higher reliabilities than the target 80% \nintegral reliability of the catalogue. The second ( PCCS2E) contains \nsources detected in sky regions where the diffuse emission makes it \ndifficult to quantify the reliability of the detections. Both the PCCS2 \nand PCCS2E include polarization measurements, in the form of polarized \nflux densities, or upper limits, and orientation angles for all seven \npolarization-sensitive Planck channels. The improved data-processing of \nthe full-mission maps and their reduced noise levels allow us to \nincrease the number of objects in the catalogue, improving its \ncompleteness for the target 80% reliability as compared with the \nprevious versions, the PCCS and the Early Release Compact Source \nCatalogue (ERCSC).

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
