Problem

A common fork setup clones the source repository as origin, adds a personal fork, and sets remote.pushDefault=fork (or branch.<name>.pushRemote=fork). Plain git push then sends the branch to the fork and keeps pulling from origin. The GitCafe mirror setup in docs/operations/development.md works the same way: origin is git.cafe and remote.pushDefault is github.

T3 Code's Push ignores both settings once the branch tracks a same-named branch. A branch topic tracking origin/topic is pushed to origin. The commits land in the source repository instead of the fork, and the panel says "Pushed to origin/topic". Without write access to the source, Push fails even though the fork is writable.

pushCurrentBranch in apps/server/src/vcs/GitVcsDriverCore.ts already reads these settings through resolvePushRemoteName for unpublished branches and for branches tracking their base. The same-name path skips it and always pushes to the tracked remote.

Change

• resolveConfiguredPushRemoteName returns branch.<name>.pushRemote, then remote.pushDefault, or null. resolvePushRemoteName keeps its old result: that value, else the primary remote.
• On the same-name path, when a configured push remote differs from the tracked remote, Push sends HEAD to the tracked branch name on the configured remote. It does not pass -u, so the branch keeps tracking origin/topic for pulls, as plain git push does. The result names fork/topic, so the panel shows where the commits went.
• When the branch already matches its tracked branch, Push fetches the push remote's branch and skips only when it already has HEAD; otherwise it pushes there.
• Push & create PR uses the push destination returned by the driver to select the PR head.
• No configured push remote, or one equal to the tracked remote, behaves as before. The base-branch and tracking-alias safeguards from fix(server): push no longer writes a feature branch's commits to its base branch #8228 are unchanged.

The refspec stays explicit, so push.default cannot change the target branch. #788 used an explicit refspec for that reason.

Scope and approval

There is no issue for this exact case. It qualifies as a small, focused fix of an obvious bug: #788 added support for branch.<name>.pushRemote and remote.pushDefault, and this path bypasses them. The up-to-date skip and the PR head follow the same push destination, so they are part of the same fix. No settings, defaults or UI code change.

Verification

Real Git tests cover both push-remote settings, preserved tracking, a fork branch that is absent, behind, deleted or rewound, and the PR head and base Push & create PR sends. Both push-remote cases fail on main 52c2b38ea4.

At 41cb117e48, vp test run apps/server/src/git/GitManager.test.ts apps/server/src/vcs/GitVcsDriverCore.test.ts passes 276/276 tests. vp run check:changed 52c2b38ea41ee2271f5aca527009d36d25432689 also passes.

Push from the app was checked on main 52c2b38ea4 and this branch at 41cb117e48: web on Linux, the desktop app on macOS, an iPhone 17 Pro simulator on iOS 26.5, and a Pixel emulator on Android 16. Each run uses a fresh repository with local bare remotes origin and fork, topic tracking origin/topic, remote.pushDefault=fork, and one new commit. On main the commit lands in origin and the fork does not receive it. On this branch it lands in fork and origin keeps its old commit. Images are cropped to the push result.

Web on main: Pushed to origin/topic.

Web on this branch: Pushed to fork/topic.

Desktop on main: Pushed to origin/topic.

Desktop on this branch: Pushed to fork/topic.

iOS on main: Pushed to origin/topic.

iOS on this branch: Pushed to fork/topic.

Android on main: Pushed to origin/topic.

Android on this branch: Pushed to fork/topic.

Not checked:

• Hosted fork pushes and hosted Push & create PR flows. Local integration tests cover the fork PR head and the base of a differently named tracking branch.
• The desktop app on Windows and Linux.
• Ahead counts still use the tracked upstream: after a fork push they remain ahead, and Push again reports success with nothing new to send. If origin is current but fork is behind, the server can push, but the client disables Push ("No local commits to push.").

Prior PRs

• Fix cross-repo PR detection and push remote selection #788 by @juliusmarminge added push-remote selection with branch.<name>.pushRemote and remote.pushDefault. This PR applies it to the tracked-branch push path, its up-to-date skip and the PR head that follows it.
• fix(server): push no longer writes a feature branch's commits to its base branch #8228 by @t3dotgg stopped pushes to a branch's base. Its checks run first and are unchanged.
• [Bug]: Fork checkouts resolve "the primary remote" four different ways, so features disagree on the repository #17314 by @tris203 described separate fetch and push remotes in fork checkouts.

Walkthrough

The push logic now supports a configured push remote that differs from a branch’s tracking upstream. It can push to that remote without changing the upstream and pass the pushed ref to pull-request head resolution.

Changes: Configured push remotes

Layer / File(s)	Summary
Resolve and push to configured remotes apps/server/src/vcs/GitVcsDriverCore.ts, apps/server/src/vcs/GitVcsDriverCore.test.ts, apps/server/src/vcs/GitVcsDriver.ts	The push logic separates configured push remotes from the primary-remote fallback. For a distinct configured remote, it checks whether that remote contains HEAD and skips or pushes accordingly. Pushes preserve the tracking upstream. Tests cover configured remotes and branch states.
Resolve the pull-request head from the pushed ref apps/server/src/git/GitManager.ts, apps/server/src/git/GitManager.test.ts	GitPushResult can include the push remote. The stacked-action flow passes the push remote and upstream branch to runPrStep, which uses that ref to resolve the pull-request head. Tests cover fork heads and tracked-branch bases.

Check the configured push remote before returning skipped_up_to_date.

When topic tracks upstream/topic and HEAD matches that upstream, pushCurrentBranch returns before it checks branch.topic.pushRemote or remote.pushDefault. If fork/topic is absent or behind, Push reports skipped_up_to_date and does not publish to fork/topic.

Resolve the configured destination before this return. Skip only when that destination already contains HEAD; otherwise run the configured-remote push. The existing skip behavior remains valid when the tracking and push destinations are the same. This is a pre-existing edge case that leaves the PR’s configured-remote behavior incomplete.

Verified in a real dev environment

Verified the push-only fix at exact head 22568fb05815a6d78dee47f279f6a0f8c1c43403 on a Linux Boat VM. No source changes or pushes were needed.

Ran vp i and background dev servers on github/main (6575ce3250, separate worktree) and this exact head, one server at a time. Used isolated state, repo Playwright, /usr/bin/google-chrome, and real Codex gpt-6.1-sol turns through the web composer. Added the project and threads in the app. Codex created and committed the files. Git used two real local bare remotes, without mocks.

Clicked Git action options > Push in the thread details panel:

• main reproduction: topic tracks origin/topic, remote.pushDefault=fork. App reported Pushed to origin/topic. Source moved to 50bdc857; fork stayed at d1bca512.
• PR, matching repository/commit: app reported Pushed to fork/topic. Fork moved to 50bdc857; source stayed at d1bca512. Tracking remained origin/topic.
• branch override: branch.topic.pushRemote=fork overrode remote.pushDefault=origin. Fork received the next Codex commit b8b836ea; source stayed at 50bdc857; tracking remained origin/topic.
• normal push: removing both settings restored origin/topic as destination. Source received 5b60123e; fork stayed at b8b836ea. Both neighboring checks also used push.default=nothing, confirming the explicit refspec still works.

Existing GitVcsDriverCore.test.ts and GitManager.test.ts passed through blacksmith-check: 268 tests, 2 files. CI reports 27 successful checks, none pending/failing.

Command transcript with full SHAs

Not verified

Hosted Push & create PR, including the changed GitManager head-selector path, was not exercised end to end: doing so requires creating or touching another PR, which this brief forbids. Its existing test passes, but that is not runtime proof. Hosted fork permissions, native desktop/iOS/Android, macOS/Windows, and relay/tunnel connections were not exercised.

Known pre-existing limitation reproduced: when HEAD equals the fetch upstream but the configured fork is behind, the app disables Push with No local commits to push. The fork stays behind. The client ahead-count guard and server early skip predate this diff. This verification does not claim that case is fixed.

🤖 Claude Opus 5.5 responding on behalf of only21mil

The up-to-date case from CodeRabbit's review and Maria's verification is now handled on the server.

• 63f29e3: when a tracked branch matches its upstream and a different push remote is configured, Push checks the push remote's branch before skipping. It skips only when that branch already has HEAD. Otherwise it pushes there.
• 7d94105: before that check it fetches the push remote's branch, so a branch deleted or rewound on the fork since the last fetch is not skipped from a stale local ref.
• 41cb117: the Push & create PR tests now record PR creation through a source control provider stub instead of gh calls, which main removed in test(source-control): forge behaviour is tested in its own package #24000.

Tests in GitVcsDriverCore.test.ts: pushes an up-to-date tracked branch to the push remote when its branch there is %s (absent, behind, deleted, rewound) and skips an up-to-date tracked branch the push remote already has. The absent and behind cases fail at 22568fb, and the deleted and rewound cases at 63f29e3, because the push is skipped.

Not changed here: the client still disables Push with "No local commits to push." in that state, because its ahead count compares with the tracked branch. Fixing that needs the git status contract to carry the push destination's ahead count, which is a separate client change. The PR description lists it under Not checked.
