fix(server): recognize authenticated GitHub Enterprise hosts

[alimek]

Repositories on custom GitHub Enterprise hosts could be reported as unsupported and disappear from the PR page even when GitHub CLI knew the host.

Recognize hosts listed by gh auth status --json hosts, including accounts with expired tokens so credential errors remain actionable. Connect this refinement to the managed discovery path now used on main. Keep Enterprise requests on the detected host while preserving GH_REPO, gh repo set-default, and upstream/origin repository selection through direct API reads, PR creation, branch lookup, clone lookup, and checkout. Checkout now matches the host as well as owner/name when choosing a remote.

Rebased onto main at 12069eefd. Enterprise targeting and regression tests now live directly in the source-control provider after main removed GitHubCli. Regression coverage includes mixed accounts, case-insensitive hosts, unavailable auth JSON, stored unknown repositories, SSH/HTTPS remotes, GH_REPO precedence and inferred-origin fork contexts, and identical repository names on github.com and Enterprise. User guidance explains Enterprise sign-in.

Validation: 440 focused tests passed across discovery, credentials, API behavior, source-control operations, and PR services. Targeted lint, server typecheck, and diff checks passed. The portable macOS arm64 build starts and serves its web client successfully. Live Enterprise verification remains for a machine with access to the corporate host.

Implemented with GPT-6 Astra through the Codex harness.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR expands production source-control discovery and API/checkout behavior to authenticated GitHub Enterprise hosts, including credential-based provider selection and host-aware repository resolution. The change affects several existing workflows and authentication-sensitive routing, so its runtime impact warrants human review.

📝 Walkthrough

Walkthrough

GitHub Enterprise discovery now resolves unknown custom-host repositories through GitHub CLI hosts. GitHub operations use repository targets derived from provider context and normalized remote URLs. Tests and documentation cover the new behavior.

Changes

GitHub Enterprise discovery and repository targeting

Layer / File(s)	Summary
Custom-host refinement apps/server/src/sourceControl/GitHubSourceControlProvider.ts, apps/server/src/sourceControl/SourceControlProviderRegistry.test.ts	The provider matches remote hosts against GitHub CLI authentication output. Tests cover authenticated, case-insensitive, failed-account, unrelated-host, and invalid-JSON scenarios.
Enterprise repository targeting apps/server/src/sourceControl/GitHubSourceControlProvider.ts, apps/server/src/sourceControl/GitHubCli.ts	Provider operations derive repository targets from normalized remote URLs. GitHub CLI commands accept optional repositories for pull request, branch, checkout, and repository operations.
Resolution and integration validation apps/server/src/sourceControl/GitHubSourceControlProvider.test.ts, apps/server/src/pullRequest/PullRequestService.test.ts, docs/user/source-control.md	Tests cover Enterprise URL formats and repository propagation. Pull request discovery coverage uses mocked GitHub CLI authentication. Documentation describes GitHub Enterprise authentication.

106-118: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

The custom-host refinement returns a GitHub provider with baseUrl, but the bound GitHubSourceControlProvider does not propagate that host to GitHubCli; its commands lack --hostname or a host-qualified --repo, so Enterprise repository operations can target the default GitHub host or fail credential verification. Pass the refined host through to the CLI for every provider operation.

I tested this against a real GitHub Enterprise host (prodgit.<company>.com, no github DNS label) and it fixes the misclassification — thanks for doing the --repo host/owner/repo threading too, that part matters once the stored repository and the cwd's default remote disagree.

One suggestion on the claim condition in refineUnknownGitHubRemote:

const authenticated = parseGitHubAuthStatus(input.auth.stdout).accounts.some(
  (account) => account.authenticated && account.host === host,
);

Consider claiming the host on presence in the hosts map, dropping account.authenticated &&. gh auth status --json hosts still lists a host whose token has expired or been revoked, just with state != "success". With the authenticated requirement, that host refines to null, the kind stays unknown, and PullRequestProviderRegistry.get("unknown") is null — so the user gets:

Change requests cannot be browsed for this project's host yet.

which is inaccurate. The host is supported; the credentials are stale. On presence alone the kind becomes github, gh fails with an auth error, and PullRequestService's providerDetail maps it to cli-unauthenticated:

GitHub CLI is not authenticated. Run gh auth login and retry.

That names the fix instead of implying an unsupported host, and it's the same shape as the existing cli-missing path. Both behave identically when credentials are good, so this only changes the expired-token case.

Not a blocker either way — the classification fix is the important half.

[alimek]

Good catch — adopted in 78ac3b2. refineUnknownGitHubRemote now claims the host on presence in the auth-status hosts map alone; the authenticated requirement is gone. The expired-token case now resolves to github, gh's auth error classifies through classifyNonZeroExit as authentication, and users get the gh auth login hint instead of the unsupported-host message. Registry table scenario for a failed custom-host account now expects github.

@xiaogwu, @alimek either of u mind testing? I pushed a change regarding the CLI->API refactor and would love confirmation whether it works or not
