5.2  Multi-Source Cross-Detector Schema Notes

Schema details are pending.

This page should eventually define source experiment records, coordinate conventions, held-out target tasks, metadata fields, splits, and example loading code.

5.2.1 Expected coverage

Area	Notes
Sources	Experiment, detector, simulation, and selection provenance
Coordinates	Per-detector geometry and coordinate normalization conventions
Tasks	Held-out target tasks and probe labels
Splits	Source, target, validation, and hidden evaluation policies
Examples	Minimal loading code for cross-detector batches
