1. Scapa Flow Industries: HQ moved from restricted military station to
Quaterna (civilian commercial platform). Overview expanded with
military/civilian context.
2. Threshold Fuel Syndicate: reconceived from "frontier east corridor
supplier" to Gateway's local fuel producer supplementing imports.
Removed frontier tag.
3. Arbour Aggregates: corridor labels fixed — "north"/"east" → "core zone"
to match GJ 338B's actual hop-3 loop_member position.
4. Rush Mining: named concrete sustaining mechanism (property tenure
uncertainty keeps combines away; first-mover holds by occupation).
5. Sede Chemical Works: expanded "ACB" to "ACB — Alpha Centauri B" on
first use.
6. Stale body footer dates updated on rush-mining and scapa-flow.
7. Bifrost Marmor: added missing Cross-References body section.
8. Rush Mining: added cross_ref to rare-vein-survey.
