Single source of truth for gap page: verification status from
verify.py (verified/untested/missing/mismatch), file provenance
from cross_reference (bios/data/large_file/missing).
cross_reference.py: _find_in_repo -> _resolve_source returning
source category, stop skipping storage: release/large_file,
add by_path_suffix lookup, all_declared param for global check.
generate_site.py: gap page now shows verification by platform,
18 hash mismatches, and core complement with provenance breakdown.
