name: PM Bundle

# Stages the self-contained agent payload for each (os, arch) target with
# `hermes pm bundle`: repo snapshot + tool store + facts + a relocatable
# venv built on the staged python-build-standalone interpreter. Each
# payload is smoke-tested on its native runner — the staged interpreter
# boots hermes_cli out of the payload with no network and no PYTHONPATH —
# as a pre-merge check for the pm tooling itself.
#
# Staging is native per target (no cross-target wheel tables anywhere):
# the runner IS the target. pm's arch guard fails the job if any staged
# mismatches, before anything ships.
