fix(server): Git status finds the default branch when the only remote isn't origin - #28815
When a repository's only remote isn't named origin (for example after git clone --origin github), Git status never finds the default branch. Status read the default branch only from refs/remotes/origin/HEAD, so it fell back to guessing main or master. On a default branch named anything else, such as trunk, every client treats it as a feature branch:
Web, desktop and iOS offer "Commit, push & PR" on the default branch instead of "Commit & push".
The default-branch confirmation never appears. On iOS, one tap committed and pushed straight to trunk.
Android's commit sheet leaves out its "You're on the default branch" warning.
To reproduce, create a repository whose only remote is github, with github/HEAD pointing at trunk. Check out trunk with an upstream, edit a file, and open a thread in it.
Change
Status now picks the remote the way the rest of the Git driver does (origin if it exists, otherwise the first remote) and reads that remote's HEAD. One helper feeds the cached local status lookup, its uncached fallback and the remote status read. The cached lookup still passes --git-dir, so worktrees of a bare repository keep working under safe.bareRepository=explicit. Cache invalidation is unchanged, and repositories with origin resolve as before.
Cost: a repository whose origin has a HEAD runs the same single lookup as before. Others run up to two more local git processes per remote status read and per 5-minute cache fill.
Scope and approval
This is a small fix for an obvious bug, with no linked issue. It applies the driver's existing primary-remote rule, which comparison-base selection and push-remote fallback already use, to the status default-branch lookup. It adds no new remote-selection policy. For maintainers to confirm:
Tests (macOS, from apps/server, vp test run src/vcs/GitVcsDriverCore.test.ts): 275 of 276 pass on this branch merged with main (01d927caa0). The one failure, "keeps generated worktree folders short without changing long branch names", also fails on unchanged main (cd8fc91) on the same Mac (/var against /private/var). With main's GitVcsDriverCore.ts under the merged tests, both new "uses the only remote's HEAD for default-branch detection without origin" cases fail.
App runs on main (cd8fc91), this branch (51681e2) and this branch merged with main (01d927caa0, local only), each with a fresh server and repository: only remote github (a local bare repository), github/HEAD → trunk, trunk checked out with an upstream, one edited file. The clients are today's main builds, since the change is server-only. I drove the phones through the T3 Device panel and web through the T3 Browser panel. Nothing was committed or pushed.
On this branch and the merged tree, "Commit & push" on web and iOS asks for confirmation before committing to the default branch (each closed without committing).

The desktop app on the present head. My Linux desktop captures (on 5863aba) predate a change to the fix's own lines (73191e5), so I dropped them. No desktop code changed.
The one-tap commit on main for iOS (Problem) was not tapped again in this run.
Android ran with software rendering, so its captures show the warning text, not layout.
The uncached status fallback has no direct test. It runs only when repository path resolution fails, and it calls the same helper.
…y origin
Git status looked up the default branch through refs/remotes/origin/HEAD
alone, so a repository whose only remote is not named origin never matched
its real default branch. Status now resolves the primary remote with the
existing rule (origin, else the first remote) before reading its HEAD.

…lookup
The driver runs Git with safe.bareRepository=explicit, so a worktree backed
by a bare repository needs --git-dir for the cached lookup, as before.
Origin's HEAD is read first, so origin repositories spawn no extra
process, and the test now also checks the ahead-of-default count.

Macroscope's review found this PR approvable — Git status now recognizes the default branch when origin is absent by reading another configured remote's HEAD. This is a local metadata lookup change that preserves origin precedence and does not modify repository data.

Walkthrough
Default-branch lookup now checks origin first and uses the first configured remote when origin is absent. The change updates cached, local, and remote status paths and adds coverage for regular checkouts and bare-backed worktrees.
Default-branch resolution accepts Git directory arguments and lists configured remotes. It uses origin when available, or the first configured remote when origin is absent.
Status integration and coverage apps/server/src/vcs/GitVcsDriverCore.ts, apps/server/src/vcs/GitVcsDriverCore.test.ts
The cache and local and remote status paths use primary-remote resolution. Tests cover default-branch status and feature-branch ahead count for regular checkouts and bare-backed worktrees.

Merge Risk: Minimal · up to 51681
Default-branch status supports a repository whose only remote is not origin, and the previously reported missing push and pull-request actions are no longer indicated by the current code. No actionable merge risk remains after normal checks.

Explanation
The description follows the repository template closely. It has Problem, Change, Scope and approval, and Verification sections, and each is substantively filled in. The Problem section gives a clear reproduction path. The Change section explains the remote-selection rule and the cache behavior, including the cost of extra git processes. The Scope section explains why no prior issue is linked and cites the existing primary-remote rule. The Verification section lists the test commands, the results (275 of 276 passing, with the one failure shown to occur on main too), and the multi-client before and after evidence, plus a list of items that were not checked. The template asks for a model and harness attribution at the end, and the description includes one (Claude Opus 5.5, GPT-6.1 Terra and GPT-6.1 Sol in T3 Code Nightly). The description is complete and specific. Its main weakness is length and density, not missing content.

Merged current main into this branch (merge commit 51681e27a6, no rebase). The one conflict was in GitVcsDriverCore.ts: main split resolvePrimaryRemoteName into findPrimaryRemoteName plus a failing wrapper. I kept main's helpers and this PR's resolvePrimaryDefaultBranchName unchanged.
GitVcsDriverCore.test.ts: 248/248 passed after the merge.
vp run check:changed against main: format, lint, knip, typecheck and tests passed.
CodeRabbit's hasPrimaryRemote finding is already fixed on main by primaryRemoteExistsCache, which this merge brings in. No code change needed.
