name: Labeler

# Reusable PR auto-labeler for all Sea-Haven-Industries repos.
#
# The label rules live HERE as the single source of truth and are written to the
# runner at execution time, so caller repos need only a short caller workflow and
# no per-repo labeler.yml.
#
# Callers trigger this on `pull_request` (NOT pull_request_target): every org repo
# is private and takes no fork PRs, so the lower-privilege event is sufficient and
# avoids the pull_request_target pwn-request surface. Because `pull_request` runs
# the workflow from the PR merge commit, the Labeler check appears on the PR that
# first adds the caller — an absent or failed Labeler check means a missing
# permission grant on the caller, not "expected" behaviour.
#
# Callers MUST grant all three permissions below. Reusable-workflow permissions can
# only be downgraded from the caller, so a caller that omits one (e.g. issues:write)
# either fails to create labels or triggers a silent startup_failure:
#   permissions:
#     contents: read
#     pull-requests: write
#     issues: write
