Candidate PR — SR12 cut point (10.0.120)

The Candidate PR promotes a specific main commit as the base for cutting SR12 (10.0.120). The SR branch can't be cut until it merges, so its status gates the whole cycle.

No open Candidate PR yet. When ready to cut SR12, open a PR titled *Candidate* against main selecting the target commit — the SR is cut from its merge commit.

Cleanup follow-ups — 3 item(s)

These are housekeeping items that should be addressed but do NOT block this release.
