Owner

The first profile=x264 build to reach STEP 7 (post #46) got a new exit-127: the encoder test binary now genuinely links libx264.so.164, but BUILD.gn:x264 deliberately sets no rpath (the runtime image provides the libs on its default path) and the build host's loader knows nothing about /work/system-libs — the binary dies at exec (error while loading shared libraries: libx264.so.164) before gtest starts. The framesink suite (no system libs) reported SUCCESS: all tests passed in the same run — plumbing works, only the loader path was missing.

Export LD_LIBRARY_PATH=/work/system-libs/lib for the test step: both binaries + future targets, appends any pre-set path, no-op for sw-profile builds.

Verify-loop onion layer 4 (lane skipped tests → profile pipe severed → stale sw binary → loader path) — each only visible after the previous was fixed. Verification build from this branch is running on t7.

The first profile=x264 build to reach STEP 7 (post profile-pipe fix
#46) got a NEW exit-127: the encoder test binary now genuinely links
libx264.so.164, but BUILD.gn:x264 deliberately sets no rpath (the
runtime image provides the libs on its default path) and the build
host's loader knows nothing about /work/system-libs — so the binary
dies at exec with 'error while loading shared libraries' before gtest
starts. Meanwhile the framesink suite (no system libs) reported
'SUCCESS: all tests passed' in the same run — the plumbing works;
only the loader path was missing.

Export LD_LIBRARY_PATH=/work/system-libs/lib for the test step:
covers both binaries and future targets, appends any pre-set path,
and is a no-op for sw-profile builds.

This is verify-loop onion layer 4 (lane skipped tests → profile pipe
severed → stale sw-profile binary → loader path), each only visible
after the previous was fixed.
