fix(server): fork PRs from origin no longer fail when gh targets upstream#23660
Problem
In a fork clone, origin is the fork and upstream is the source repo. If gh resolves upstream as the base repo (via gh repo set-default, or by its own remote ranking, where upstream beats origin), Create PR fails for a branch that tracks origin/<branch>. The error is createChangeRequest: GitHub returned an error: Validation Failed; head invalid.
The provider creates the PR in the resolved base repo (POST repos/<upstream>/pulls). But resolveBranchHeadContext decides whether the branch is cross-repository by comparing its remote against the remote literally named origin. Here the branch's remote and origin are both the fork, so the head is sent bare (<branch>) instead of <fork-owner>:<branch>.
Reproduced on main (f054d1b801) with the real dev server and web UI. The checkout had origin = juliusmarminge/t3code, upstream = pingdotgg/t3code with remote.upstream.gh-resolved base, and branch fix-7382-repro tracking origin/fix-7382-repro. Clicking Create PR sent {"base":"main","head":"fix-7382-repro",…} to repos/pingdotgg/t3code/pulls.
Change
When runPrStep creates a GitHub PR, it now resolves the repository the GitHub provider targets: GH_REPO, else resolveGitHubRepository over the remotes and their gh-resolved marks, the same resolution the provider uses. If the head remote's repository differs from that target, the head is sent owner-qualified (<owner>:<headBranch>). Otherwise the existing preferredHeadSelector is used unchanged.
resolveBranchHeadContext and isCrossRepository are not changed. Status, PR lookup and base resolution behave as before. The extra git config read runs only when a PR is created, never on the status path.

Evidence
Head 33a1b866ae, merge-base 60b35a1ee0. The "After" column above was captured at d0adb0e588 and is superseded by the head capture below. The PR-create request body is unchanged between the two.
Each row ran the real GitManager and the real GitHub source control provider through a driver script. A globalThis.fetch stub logged every GitHub API call and answered POST …/pulls with a stub 422, and a fake gh sat first on PATH. Pushes went to local bare repos via pushInsteadOf. Global and system git config were isolated. Nothing was created on GitHub. F = juliusmarminge/t3code (fork), U = pingdotgg/t3code, branch fix. Fixture matrix: matrix.md.

At head, every create row that reaches PR creation on GitHub runs git config --get-regexp ^remote\..*\.(url|gh-resolved)$ exactly once. The merge-base never runs it, and rows 5 and 5b don't run it at either SHA.

Verification log
Reviews (one round, full diff vs merge-base, at head 33a1b866ae)
- Claude Sonnet 5.5: MERGE. Low, non-blocking: a custom-domain GitHub Enterprise origin, or an SSH host alias, isn't detected as GitHub by URL, so the target resolves to null and the old bare head is sent. That matches main and isn't a regression. Also: raw config URLs vs
git remote -vdiverge underinsteadOf, and theGH_REPOhost is ignored in the name-only comparison. The added status test passes on the merge-base, so it guards existing behavior only. - Claude Opus 5.5: MERGE. Same Enterprise/SSH-alias finding; suggests taking the host from
provider.baseUrlin a follow-up. ProbedGH_REPOforms, scp/HTTPS URLs, twobasemarks,owner/repomarks, multi-URL remotes, dotted remote names and case, and found no input that newly owner-qualifies a head that should stay bare. - Sensitive surface: none. Parser cost on ~3000-token malformed input: at most 1.7 ms per call, no backtracking.
Tests
vp test run apps/server/src/git/GitManager.test.tsat head: 106 passed (tests-head.log).- Head's test file run against merge-base code: 1 failed, 105 passed. The failing test is
creates fork PRs from origin with the fork owner selector when gh targets upstream(Expected: "juliusmarminge:fix-7382-repro",Received: "fix-7382-repro") (tests-mb-with-new-tests.log).
CI: 35/35 checks successful on 33a1b866ae.
Proof audit: pass 2 reran row 1 at both SHAs and got byte-identical output to the transcripts (audit2.md, rerun-row1-before.txt, rerun-row1-after.txt). Verdict: sufficient.
Corrections to the description above
- "the same resolution the provider uses": the order matches (
GH_REPO, thenresolveGitHubRepository), but this code reads rawremote.*.urlwhile the provider readsgit remote -v(insteadOfapplied). It also returns null unless origin is detected as GitHub by URL, and it takes the host from origin rather thanGH_HOST. In those cases the old head is sent, as on main. - "It also checks that the created fork PR is found afterwards": that lookup uses scripted fake
ghoutput. Agreement with the real provider is shown by rows 1–4b above.
Unverified: row 9 (origin with a 3-segment path; unit-level only) was not staged. Row 10 (insteadOf rewrites) fails as an unknown provider before reaching the new code at both SHAs, so the predicted divergence wasn't reproduced. A real PR creation against GitHub wasn't checked, because all writes were stubbed. No web UI still was captured at head.

Explanation
Issue
#7382requires fork-to-upstream PR creation when gh resolves a non-origin base. The change adds target-repository resolution from GH_REPO or remote gh-resolved data. In runPrStep, it sends <owner>:<branch> when the head repository differs from the target. Otherwise, it retains preferredHeadSelector. The added test verifies juliusmarminge:fix-7382-repro and the created PR number. The status test verifies that status does not inherit the fork PR. The reported merge-base failure and head test result support the fix. The documented Enterprise, SSH-alias, and insteadOf limitations do not leave the stated HTTPS fork workflow unmet.

Not changing this one (CodeRabbit's outside-diff note on resolveGitHubTargetRepository). The two resolutions differ only when an insteadOf rule rewrites a GitHub remote to a different owner or repository. In that case this code falls back to the head main sends today, so it is a narrow edge the fix does not reach, not a regression. Routing it through the provider's own resolver would need a new provider method and contract change, which is beyond this bug fix.

Use the current provider test harness.
makeManager accepts providerScenario and returns providerCalls; it does not accept ghScenario or return ghCalls. Both tests fail when they read ghCalls, and their configured PR responses are ignored. Convert the fixtures to FakeChangeRequest arrays and assert against providerCalls.

✅ Confirmed as addressed by @juliusmarminge
Fixed in bafe500b0d: the fork test now uses providerScenario/providerCalls. The status test was dropped since this PR no longer touches status.
@juliusmarminge The supplied code confirms that the fork test uses providerScenario and providerCalls and still checks the owner-qualified head selector. The status test is also removed. This addresses the finding.

Define or import the five names used by resolveGitHubTargetRepository.
detectSourceControlProviderFromGitRemoteUrl, urlHost, parseGitHubRepositorySelector, environment, and resolveGitHubRepository are used at lines 1477–1482 but have no import or declaration in apps/server/src/git/GitManager.ts. The typecheck reports TS2304 and TS2552 for these names, and the CI typecheck step fails with exit code 1. When this function runs, line 1477 can throw a ReferenceError before the GitHub target repository is resolved, which can block GitHub PR creation for repositories with an origin remote. Import each name from the module that exports it, or pass the value in as a parameter. The compiler's suggestion, resolveGitHubTargetRepository, is the function that contains these calls, so it does not replace any of the missing names.

✅ Addressed in commit bafe500
Fixed in bafe500b0d: the local resolver is gone. GitManager now asks the provider's createsChangeRequestsIn hook (targetsRemote), and the GitHub hook ranks every remote like createChangeRequest does.
@juliusmarminge The supplied GitManager.ts confirms that the local resolver and its five undefined references are gone. targetsRemote now delegates to the provider’s createsChangeRequestsIn hook. This addresses the undefined-reference finding.

An unparseable GH_REPO falls through to resolveGitHubRepository, which considers remotes and gh-resolved with the provider's host context. GitManager head classification must follow these provider semantics; a sole remote does not by itself establish a same-repository head.

- Merge branch 'main' into fix/issue-738276f4c89
Thanks @juliusmarminge for the earlier fix and detailed runtime proof. This branch now conflicts with main, while #32262 by @exherb addresses the same fork-to-upstream PR creation failure and merges cleanly. Closing this as a duplicate in favor of that live PR.
