# Least privilege at the top, widened per job below. This workflow runs on
# pull_request_target and issue_comment, so it holds full secrets on every fork
# PR and on any comment anyone writes — the one place in this repository where a
# compromised action would be handed a repo-write token. It does not check out
# or execute PR code, so there is no pwn-request path today, but the blast
# radius should not depend on that staying true.
#
# contents: write in particular was never used: the signature records are
# written to rustfs/cla through the scoped app token created below, and nothing
# here writes to this repository's contents.
