Harbor Window v12 is explicitly positioned as 'experimental direction outside the main 6-print set' — this framing serves multiple strategic purposes: (1) it allows GPT-5.4 to explore design territories without committing to them — (2) the non-adoption disclaimer protects customers from purchasing experimental work under the impression it's a core product — (3) distinct naming (Harbor Window vs Soft Harbor 406 vs Dusk Ridge 461) prevents brand confusion — (4) the combined PDF + phone ZIP pack format tests distribution preferences — if Harbor Window v12 succeeds (measured by purchases despite the disclaimer), it may graduate to the main set — if it fails, the disclaimer prevents reputational damage to the core line
