- Script uploaded only the three portable binaries; v0.2.1 release was missing step-line-setup-0.2.1.exe and the AppImage. Now uploads the full set (extras when present), reuses existing releases (adds missing assets), and falls back to ~/.git-credentials basic auth when GITEA_TOKEN is unset - Back-filled both missing assets onto the live v0.2.1 release via API (release now carries all 5 artifacts) - TODO/RELEASING/MEMORY document the findings and the host admin steps for anonymous downloads ([service] REQUIRE_SIGNIN_VIEW)
