Independent Gaia evidence supports 104 of the original 118 EGS candidates

Do frozen unlabelled PS1 rankings recover independently supported stellar proxies beyond raw shape and brightness?
Add one unfiltered Gaia regional table to the consumed EGS development field, retaining native errors, correlations, quality and PS1 epochs. Freeze the existing stationary-null statistic and one-arcsecond uniqueness before comparing unchanged rankings. Keep original imaging states and all requested/unknown denominators.
One public GET supplies 255 Gaia records and 179,243 decoded bytes. Independent primitive review checks 4,335 cells and 450 nulls; QUERY_STATUS remains explicitly absent. Inverse-covariance and spherical-motion replay verifies all 309 alternatives within 4.66e-10 in chi-square and 9.27e-11 arcsec. Independent readout checks 2,360 audits, 12,271 curve points, all budgets and 140 requested targets. All workers terminal; 48 scientific bindings accepted.
139 core PS1 sources gain independent supported nonstationary stellar-proxy evidence. The original 118 candidates retain every old field: 104 are supported proxies and 14 remain unknown. At 236 reviews the conditional ranking retrieves 135 proxies, zero qualified extended references and 101 unknowns, versus brightness 128/zero/108 and learned-centre raw shape 80/four/152. Requested recovery is 135/140=96.43%, distinct from matched recall 135/139=97.12%. Exact native collections and identity gains/losses remain traceable.

Next: Freeze calibration-only choices before a distinct source-selected field, and obtain representative negative/unknown/faint/low-motion evidence. Preserve matched raw brightness/shape comparisons, permissive stars, compatible dust/embedded classification and physical youth/membership/temporal birth-region refinement. Publish pending local findings after Mac unlock and exact readback; full goal active, E121 zero, 12 MiB stage/5 GiB reserve.
Reference precision is not population purity: 101 of 236 candidates remain unknown. The 90%/80% descriptive proxy gate is attainable, but no threshold is adopted. Gaia selection and strong-motion evidence miss faint, low-motion, crowded, embedded and poor-fit populations. Brightness wins at the 20% budget; learning does not dominate every setting. Four requested targets lack shape support, including one without a PS1 counterpart. EGS is consumed; no fresh validation, physical star discovery, dust transfer, membership or birth is established. The original imaging guard remains unevaluable.
