+Ops incidents handled during rollout (all environmental, none code):
+- macOS CI: xlings llvm default bump 20.1.7→22.1.8 broke (a) hardcoded sandbox
+  path → fixed by dynamic discovery, (b) libc++ ABI (__hash_memory undefined at
+  link) → pinned 20.1.7, real fix belongs to hermetic-link track.
+- publish-ecosystem hung >1h on one GitHub asset upload (0.0.84 took 2min);
+  cancelled, mirrored manually: the stuck asset re-uploaded instantly, GitCode
+  side completed with per-file 200 verification.
+- xim-pkgindex linux-install-test: transient scode index fetch flake + the
+  missing asset 404; green after asset fix + retrigger.
 
 Decision taken during execution (user-directed): `--strict` semantics are the
 DEFAULT of `xpkg parse`; the escape flag is `--allow-unknown`.
