Mobile release candidates (`mobile-vX.Y.Z-rc.N`) are currently created
by the `mobile-release-candidate.yml` workflow, using the
`buzz-release-bot` App key that also serves the desktop, relay and chart
lanes. This PR takes mobile off that key. After it lands, the only way
to create a mobile candidate tag is for a person on the mobile release
team to push it.
### What changes
- `scripts/mobile-release.sh candidate` keeps all its existing checks:
version, source branch, clean tree, canonical origin, ancestry and next
rc number. It no longer dispatches a workflow. It now:
- verifies the mobile tag ruleset 26588677 (active, the expected rules,
scoped to `refs/tags/mobile-*` or `refs/tags/mobile-v*`, and bypassable
by the current user), and that the App-only general tag ruleset 14378754
excludes `refs/tags/mobile-*`;
- requires origin's effective push URLs to be exactly its fetch URL, and
fetches a pinned `--commit` missing from a shallow clone;
- creates the annotated tag locally and pushes exactly that ref
(`--no-follow-tags`, explicit refspec);
- confirms through the GitHub API that `block/buzz` holds that exact tag
object, then verifies the remote tag as before.
A rejected push removes the local tag only when origin lacks it, so a
retry starts clean. When the push reports failure but origin has the
tag, the script keeps the local tag and still runs the canonical GitHub
check, reporting success only if it passes. When GitHub can't confirm
the tag, the local tag is kept and the message says how to reconcile it.
- `scripts/release-rulesets.sh`: `require_mobile_release_tag_ruleset`
replaces the App-oriented check. `MOBILE_RELEASE_TAG_RULESET_ID` is
`26588677`.
- Removed `.github/workflows/mobile-release-candidate.yml`,
`scripts/publish-mobile-release-candidate.sh` and its test, and their CI
references. Updated `RELEASING.md` and the auto-tag workflow header
comment.
- The desktop, relay and chart auto-tagging is unchanged.
### Rollout
Tag ruleset 26588677 ("Restrict Mobile Tags") is active with the two
mobile release managers as bypass actors. The App (Integration 4349119)
is temporarily a bypass actor of 26588677 and 19321162 so the current
`main` workflow keeps working; it is removed from both right before this
merges. General tag ruleset 14378754 now excludes `refs/tags/mobile-*`;
without that, rulesets stack and it would reject release managers'
mobile tag pushes. The branch ruleset 19321162 now has the same bypass
actors, so `require_mobile_release_branch_ruleset` no longer requires
"no bypass"; it still checks the review and status check policy. Release
managers must be bypass actors of both rulesets.
### Before merge
- [x] Remove Integration 4349119 (`buzz-release-bot`) from the bypass
actors of rulesets 26588677 and 19321162.
### Validation
- `shellcheck -x scripts/release-rulesets.sh scripts/mobile-release.sh
scripts/mobile-release-source.sh
scripts/test-mobile-release-contract.sh`: clean.
- `scripts/test-mobile-release-contract.sh`: passes. It runs against a
local bare remote with a stubbed `gh` and covers:
- a successful annotated push at the pinned SHA;
- ruleset failures (not bypassable, inactive, wrong rules, wrong scope,
excludes, non-numeric ID), with `refs/tags/mobile-v*` also accepted as
the include, each failing before any tag is created;
- a push rejected by a pre-receive hook, which leaves no local tag and
allows a clean retry;
- `push.followTags=true` with a stray local annotated mobile tag
(exactly one ref published), a push that lands but exits non-zero (tag
kept), and a GitHub API outage after the push (tag kept, rerun publishes
the next rc);
- origin push URLs pointing at a fork (pushurl, a second pushurl,
pushInsteadOf, insteadOf), a shallow clone pinning a historical commit,
and 14378754 lacking the mobile exclusion;
- rc numbering, source branch rules and `--commit` pinning.
- `scripts/test-release-ref-contract.sh` and
`scripts/test-desktop-release-candidate.sh`: pass.
- Live read-only check against real GitHub as a bypass actor: sourced
`scripts/release-rulesets.sh` and `scripts/mobile-release-source.sh`,
then ran `require_mobile_release_tag_ruleset` (including the 14378754
exclusion check) and `require_mobile_release_branch_ruleset
mobile-v0.27`. Both returned success. No tag was created.
- No mobile app test: this is a script and workflow change only.
