ci: pin actions/checkout to full SHA in back-merge workflow#552
Merged
Conversation
The back-merge workflow (#548) used actions/checkout@v4, which fails the databrickslabs/ontos policy requiring all actions be pinned to a full-length commit SHA. Pin to the same SHA the other workflows in this repo already use (df4cb1c069e1874edd31b4311f1884172cec0e10 # v6).

LGTM. Pure supply-chain hardening — pinning a third-party Action to a full SHA. Recommended practice. CI green, no runtime code touched.
