ci: release App for nightly tag moves and nightly-next promotion - #17116
Conversation
The publish job mints a token with contents and workflows write to move the nightly/rc tag. manaflow-glaeda-route (GLAEDA_ROUTE_APP_*) has no contents permission, so that mint cannot work. A dedicated release App with only Contents and Workflows write replaces it; its id and key are the release environment secrets CMUX_RELEASE_APP_ID / CMUX_RELEASE_APP_KEY. Do not merge before the App exists and those secrets are set. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The cmux-next NIGHTLY track publishes from the protected branch nightly-next. Moving that branch needs the release App key, which must not be reachable from feat-cmux-next (anyone can push there). nightly.yml on main gets inputs promote_nightly_next_sha / promote_nightly_next_debounce and a job promote-nightly-next in the release environment (main + v* only): it accepts only a feat-cmux-next SHA whose cmux-next.yml push run passed the Release compile, debounces requested promotions to one build per 2 h, fast-forwards nightly-next (or replaces a hand-made baseline that left feat-cmux-next), and builds nothing in that run (own concurrency group, decide skipped). feat-cmux-next requests it with gh workflow run (e6cfc0f there).

Use a promotion timestamp for the debounce check.
.github/workflows/nightly.yml accepts pushes only on main and rc/**, so promoting nightly-next cannot create the push run queried here. When debounce is enabled, the check can miss a promotion and allow another eligible SHA within the interval. Record the promotion time when updating nightly-next, and use it for debounce.

The diverged-history force path can move nightly-next to a commit that is not an ancestor of feat-cmux-next.
Lines 515 and 545 do not check that sha is an ancestor of sourceHead. A push run on feat-cmux-next for that SHA proves only that the SHA was the branch head at one time. That SHA can become unreachable after a later force-push to feat-cmux-next.
In the diverged case, Line 570 checks only that merge_base(current, sha) is on feat-cmux-next. This check does not prove that sha descends from the current source history. Consider an orphaned old head. Its merge base with current can be an older commit on feat-cmux-next. The workflow then force-updates nightly-next to history that was rewritten out of feat-cmux-next. The comment at Lines 565-566 states that the branch "never moves to older history", but the code does not enforce that claim.
Require that sha is on feat-cmux-next before the code tries any ref update.
Proposed fix
const sourceHead = (await github.rest.git.getRef({ owner, repo, ref: `heads/${source}` })).data.object.sha;
+ const { data: shaOnSource } = await github.rest.repos.compareCommitsWithBasehead({ owner, repo, basehead: `${sha}...${sourceHead}` });
+ if (shaOnSource.status !== 'ahead' && shaOnSource.status !== 'identical') {
