Yogthos e0c1564ff9 Tree-shake: count #'x references; multi-app soundness smoke ... Two things, both from studying Stalin's closed-world DCE: 1. Soundness fix: dce-collect-refs now counts a :the-var (#'x / (var x)) reference, not just a :var. Stalin's rule is that ANY reference — value position, not only a direct call — keeps the target live; a var referenced as #'x would otherwise be wrongly dropped. (My :var collection already covered value-position refs; this closes the the-var hole.) 2. host/chez/tree-shake-smoke.sh (make shakesmoke): builds example apps default vs --tree-shake and requires identical output — the real risk is shaking a binary that pulled libraries via deps.edn. Covers markdown/malli/commonmark/hiccup (git-lib apps). All produce byte-identical output shaken vs not, and drop ~0.8-1MB (malli 10.0MB -> 9.0MB) from the compiler-drop. Slow; not in the default gate. Skips without the examples repo.		2026-06-23 20:27:21 -04:00
