Build pinned LGPL playback libraries and package standalone YouTube helpers inside the signed native app. Keep the CLI inside the app and relocate private library links for installation without runtime Homebrew dependencies.
Record adaptive fixture completion in its EXIT trap: cancellation can exit with status 143 before the TERM trap writes its marker, while native pause and quality preservation remain correct.
Add make release and make install PREFIX=/Users/valdemar/.local. Keep optimized no-debug release artifacts separate; install adjacent CLI/app under lib/terebi and link bin/terebi. Preflight FFmpeg/pkg-config before compiling or installing, including cached builds.
Record the player's exact linked FFmpeg ABI paths. AppKit-only CLI/bootstrap validate native loadability and transitive dependencies before entering the FFmpeg-linked terebi-player. CLI fails with status 69 and remediation; Finder bootstrap shows a native alert and execs the player without losing initial events or process identity.
Verified staged installation with spaces, reinstall preservation, absent build dependencies, missing/corrupt/transitively broken dylibs, real modal error surface, installed CLI and Finder startup across exec, local/YouTube resume and window reuse, and full make check.
