peer-drift.yml

name: Peer drift report

# Weekly: the cross-SDK suite (cross-sdk.yml) and the framework smoke matrix (framework-smoke.yml)
# against the latest commit of every peer SDK, instead of the commits peers.json pins. A red run
# here means a peer moved in a way the pinned suite has not caught up with: adapt the programs or
# expectations, then move the pin (integration-testing/README.md, "Peer pins and drift").
#
# Informational only. It runs on a schedule and on manual dispatch, never on push or pull request,
# and no other workflow, branch rule or release step depends on it. The release gates are
# cross-sdk.yml and framework-smoke.yml at the pinned peers.
