Archive the father as well as the mother; how many represses a mother carries
Decided (October 2026): the plant keeps the father and the mother of every side. production-timeline.md (repress section) records the decision and the rule of thumb with sources: about 10 stamper sets per mother before it degrades (Third Man Pressing FAQ, a Nashville plater via WPLN), fewer in quality-minded sources (5 VinyLab, 6 to 8 Stereo Review 1962); a father grows about 5 to 10 mothers. So a mother covers roughly ten represses (10,000 to 20,000 records a side) and a worn one is replaced from the archived father without a new cut. galvanics.md: 4 archived parts per title, ~1,200 to 2,400 a year; new open question to all galvanics candidates (sets per mother, mothers per father, storage). artist-platform.md repress paragraph. Demos: make-a-record and artist-order say father and mother are archived; factory console archives the father on represses too, counts stamper sets per mother (shown in the genealogy and the customer's metal card), and the metal archive counts fathers and mothers.
