- COE 1.6.8 races kubejs-create for the ProcessingOutput rhino wrapper
(guard flag set in @Mod ctor, KubeJS plugin callbacks run during its own
construction) → nondeterministic 'Wrapper already exists!' boot crash.
Ship ASM-patched jar (tools/patches/build_patched_coe.sh, Patcher.java).
- validate_pack.py: new 'remote' command — fetches every direct URL and
byte-verifies non-CDN hashes; catches unpushed/ drifted patched jars.
- docs/server.md: stale-metadata failure row (-g is GUI-only), patched-jars
table; docs/mods.md compat notes.
The node:20-bullseye runner image ships Python 3.9, which lacks
tomllib (3.11+). Extract inline workflow validation into
tools/validate_pack.py using regex-based parsing of the machine-
generated packwiz TOML subset, and call it from the workflow.
