Push260828: glibc 1.18.15 + native 1.18.21 + native-upx (compressed) + standalone (transitional)

Push260828 — four runtime families, first co-appearance (transitional formal release)

Special formal release where all four runtime families appear together for the first time. Transitional in nature: the native bionic line is becoming the mainline, the glibc wrapper line is demoted to appendix maintenance, and opencode-glibc-standalone is introduced as a frozen single-version rollback package.

Family	Assets	Coexistence
glibc (wrapper line, stable appendix)	opencode-glibc_1.18.15_aarch64.deb, opencode-glibc-1.18.15-1-aarch64.pkg.tar.xz	mutually exclusive with native / compressed
native (bionic mainline)	opencode-native_1.18.21_aarch64.deb, opencode-native-1.18.21-1-aarch64.pkg.tar.xz	mutually exclusive with glibc / compressed
native-upx (compressed ELF)	opencode-1.18.21-aarch64-android-native-tui-upx.xz	manual ELF drop-in, not a package
standalone (frozen rollback)	opencode-glibc-standalone_1.18.15_aarch64.deb, opencode-glibc-standalone-1.18.15-1-aarch64.pkg.tar.xz	CAN coexist with opencode (independent lib path, entry opencode-glibc)

opencode-glibc-standalone ships a single frozen version (1.18.15) for rollback only. The glibc / native / compressed families remain mutually exclusive providers — installing one replaces the others.

Size / startup tradeoff (measured, not marketing)

179,807,785 B → 51,891,796 B (UPX --best, 28.86% retained) → 50,362,704 B after xz -9 (UPX output is high-entropy, so xz gains only ~3%). Startup overhead: +0.7–1.1s (measured 1.9–2.3s vs 1.1s for the unpacked ELF). Choose the compressed ELF only if download size matters more than startup latency.

Antivirus false-positive notice

UPX-packed executables may trigger antivirus heuristics. This is a known phenomenon with packed binaries, not malware. Trust the sha256 values above / SHA256SUMS.txt, not AV verdicts.
