| # Runs at 20:00 UTC daily — offset from the main tracker (06:00 UTC) to avoid | |
| # saturating runners when stable-branch builds are active. gnome-build-meta | |
| # master nightly finishes ~08:00 UTC, so 20:00 UTC ensures new artifacts are | |
| # in the CAS before we open a junction-bump PR. | |

| # ── Track core junctions for next (btw stream) ───────────────── | |
| # Bumps gnome-build-meta.bst (master) and freedesktop-sdk.bst atomically on | |
| # the next branch. Opens a PR against next with auto-merge enabled — | |
| # next is a fully automated rolling nightly stream, no human gate required. | |
| # | |
| # When gnome-build-meta cuts a stable branch (e.g. gnome-51 ~Sep 2026), update | |
| # track: master → track: gnome-51 in elements/gnome-build-meta.bst on next. | |
