Regional PACS inputs cover all eight optical-missed Class0 targets

Can source-selected native far-infrared catalogue inputs restore availability for embedded young-source candidates missed by the frozen optical screen?
Fix the consumed Orion rectangle and75arcsec padding before querying all six HPPSC2 reliable/rejected band lists without target/class/flux predicates. Review metadata first; retain raw native identities, units, nulls, map alternatives and all requested HOPS/VISION states. Freeze5arcsec positional availability and radius/offset controls without fitting.
One metadata GET supplies120column definitions; six unfiltered public source GETs yield717padded entries/483core. Independent DOM/Decimal review verifies14340native cells/859nulls and F/error vsnativeSNR consistency. Raw parent replay checks305466VISION primitives/95402nulls and36956HOPS primitives. Separate haversine replay verifies8953896admissions,180geometry summaries and all32HOPS/84VISION contexts within8.995e-11arcsec. Original null-counter double-count is retained under an additivev2 report-only correction; all workers terminal,90scientificbindings accepted.

Next: Register class-independent multi-band association and compatible unlabelled regional infrared/dust embeddings on distinct development inputs. Compare raw brightness/colour, retain missing/ambiguous/censored views, and freeze before representative starless/contaminant and fresh transfer evaluation. Preserve permissive optical/Gaia stars and physical ownership/membership/age/temporal birth-region scope. Publish pending E136-E152 after Macunlock/readback; full goal active,E121zero,12MiBstage/5GiBreserve.
Input availability is not detector recall, class probability or physical ownership. Six HOPS YSOs lack reliable primary inputs; any reliable/rejected proximity covers21of26. Reliable160has10HOPS alternatives but only5unique; rejected160has12and0. Shifted5arcsec HOPS controls have2/1/2core reliable70/100/160alternative contexts.717entries are band/map measurements, not717stars. Both lists already pass upstream supervised real/spurious filtering; rejected includes lowSNR/duplicates, not clean negatives. PACS/HOPS may share observations; fluxerrors/SNR are simulation-estimated and positional errors are centroid differences. VISION/HOPS overlap; ordinary-star completeness, representative purity and physical birth remain unproved.
