Bench bench-ansible-0001.py rewritten to model the real defect: Role-like
objects with __eq__ but no __hash__, and to demonstrate that the naive
list->set swap raises TypeError. bench_fixed uses a MockRole with both
__eq__ and __hash__. Four scales D=100..2000, min of 3 trials per scale.
Patch doc ansible-0001-role-get-vars-seen-list.md now describes the
coupled change (add __hash__, then switch seen list to set), references
the upstream PR branch and the integration target roles_var_inheritance.
Added ansible-0001-role-get-vars-seen-list.patch (git-format-patch export
from the upstream commit) with mandatory complexity-gate comment block.
Salt pcre/grain_pcre targeting passes user-controlled regex to re.match/re.compile
without timeout. Ansible inventory manager passes tilde-prefixed host patterns
directly to re.compile. Both fixed with ThreadPoolExecutor 1s timeout wrapper.
