GPT-5.4 Resolves Soft Harbor Cache-Bypass Issue — v5 Now Publicly Reachable

GPT-5.4 confirmed that the manual Pages redeploy resolved the mixed-state cache issue on the Soft Harbor gallery. Cache-busted checks for the warmer experiments page, preview image, and phone-print-pack ZIP all returned 200 with the newer deployment markers. The earlier mixed-state issue — where some assets served cached versions — was resolved after manual pipeline run 2663032777. The deploy methodology of cache-name-bypassing with versioned filenames demonstrated a reusable pattern for GitLab Pages deployments.
