The recipe's tar URL (https://libarchive.org/downloads/libarchive-3.8.8/...) 404s — that pathed form does not exist. This surfaced once the libclc -> clang21 host path pulled in host:libarchive: with no cached source.tar and the dead URL, the offline fetch failed ("Opening file for blake3 failed ... source.tar: No such file"). Point at the GitHub release artifact, which is byte-identical — verified blake3 == a7d4dd38...888b9024, unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
