about

nx_galx_compact.nx -- one-shot driver: fold the galx-prod store's many one-seg-per-image segments into ONE via the cap-aware ss_compact_cap (LM-028), so /img dedup + browse stop re-reading thousands of seg files per lookup (O(n)->O(1) file opens). Sovereign; the gate _ss_compact_cap_gate proves the merge is loss-free incl. segments past the 256th. Usage: nx_galx_compact <segid> (segid = a unique high id for the merged segment, e.g. 9000001; must not collide with an existing seg-<id>). The pre- compaction live manifest is preserved at galx-prod-manifest.txt.bak.precompact and every retired segment file stays on disk + is named in galx-prod-manifest-archive.txt = fully reversible. license_tier: ORIGINAL
