The rest of the server's GitHub use still spawned gh: branch PR lookups, pr view, repo view/create, pr create, pr checkout, link previews, the media proxy token, and discovery. This layer moves all of it to GitHubApi and deletes GitHubCli.execute. After this PR, the only gh processes are gh auth token, gh --version and gh auth status.

Head lookups use the same batched GraphQL as before, with no gh fallback. owner:branch filters on the head owner.
pr view accepts a number, a URL or a branch.
Repo info and the default branch come from GET repos/O/N.
Creating a PR posts to repos/O/N/pulls, using owner:branch for a fork head. Creating a repo posts to user/repos or orgs/ORG/repos.
Checking out a PR is plain git:
- The head branch is fetched from the base remote, or from a fork remote added with ensureRemote.
- If that fails, it falls back to refs/pull/N/head.
- With --force the local branch is reset.
- Branch naming follows gh.
Repository resolution no longer leans on gh's cwd logic. The order is GH_REPO, then gh's own remote ranking (selectGitHubBaseRepository), then the top-ranked GitHub remote. A dotless SSH alias containing "github" (like github-work) maps to github.com.
The media proxy takes its token from GitHubCredentials, and its private cache is gone. Link previews use REST.
Discovery: with GH_TOKEN set, GitHub is available and authenticated through GET user. Otherwise gh auth status works as before.

Expected impact

The branch → PR lookup was the one path that ignored the rate-limit guard:

	Before	After
"GitHub API rate limit exceeded" warnings	84,501 (Oct 4–6)	stops at the first refusal; host paused until reset
Duration	195 hours with errors, ~30 h continuous	at most one refused call per reset window
Peak / average	~1,259/h / ~433/h	—
GraphQL quota during the storm	held at 0 for the whole account	recovers at reset
`gh pr list --head` spawns / hour	~51	0 (batched GraphQL)
`gh pr checkout`	`gh` process	plain git

Measured on our own nightly install: 2.06 h of traces (213k spans), its boot log (Oct 4–6), and live rateLimit { cost } probes against #16320. The old code didn't record what each gh call was, so per-path counts come from span ancestry; treat them as rough. The new tracing records operation and GraphQL cost on every request, so the next measurement is a direct query.

Stack: #16319 → #16320 → #16321 → #16322

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This XXL migration replaces GitHub CLI behavior across authenticated media, discovery, repository/PR operations, and local checkout with new API and git logic, creating a broad runtime and security-sensitive blast radius. Unresolved findings include possible bearer-token disclosure, incorrect repository/PR selection, incomplete fork lookup, and checkout risks.

Not approved because:

📝 Walkthrough

Walkthrough

GitHub source-control operations now use GitHubApi and Git operations instead of most GitHub CLI process calls. Provider discovery and linked-subject lookups use GitHubApi. GitHub media fetches obtain credentials through GitHubCredentials.

Changes

GitHub source-control API integration

Layer / File(s)	Summary
Repository resolution and pull-request reads `apps/server/src/sourceControl/GitHubApi.ts`, `apps/server/src/sourceControl/GitHubCli.ts`, `apps/server/src/sourceControl/GitHubCli.test.ts`, `apps/server/src/git/GitManager.test.ts`, `apps/server/src/sourceControl/gitHubPullRequests.ts`	GitHubCli resolves repositories and pull-request references, performs GraphQL reads, and maps API errors to its error types. GraphQL requests accept an optional response-size limit. Tests cover repository selection, pull-request lookup, and API error mapping. The single-record JSON decoder was removed.
Repository writes and pull-request checkout `apps/server/src/sourceControl/GitHubCli.ts`, `apps/server/src/sourceControl/GitHubCli.test.ts`	Repository and pull-request writes use REST requests. Checkout fetches pull-request branches and creates or updates local branches through Git operations.
Provider discovery and linked-subject lookup `apps/server/src/sourceControl/GitHubSourceControlProvider.ts`, `apps/server/src/sourceControl/SourceControlProviderRegistry.ts`, `apps/server/src/sourceControl/GitHubSourceControlProvider.test.ts`, `apps/server/src/sourceControl/SourceControlDiscovery.test.ts`, `apps/server/src/sourceControl/SourceControlProviderRegistry.test.ts`	Discovery validates an available environment token through GitHubApi. Linked-subject lookup uses GitHubApi with a timeout and response-size limit. Provider registration uses the generated discovery result.
Runtime and test dependency wiring `apps/server/src/server.ts`, `apps/server/src/git/GitManager.test.ts`	The runtime provides the source-control registry and GitHubCli layer separately. Test layers provide GitHubApi mocks, and the GitManager fake no longer exposes the removed `execute` operation.

GitHub media credentials

Layer / File(s)	Summary
Media credential lookup `apps/server/src/assets/GitHubMediaFetch.ts`, `apps/server/src/assets/AssetAccess.test.ts`	Media fetches look up the github.com credential through GitHubCredentials. The token cache is removed, and the test covers failed and successful credential lookups.

Merge Risk: 🔵 Low · up to 0a6c9

This change moves the server's remaining GitHub operations from the gh CLI to direct API and git calls. Several earlier concerns are still open, all bounded in impact:

Misleading error messages, such as repository 404s reported as "Pull request not found", and discovery failures reported as a rejected token.
Raw git error text reaching users.
Host selection edge cases with GH_HOST and SSH aliases.

These should be addressed or accepted as follow-up, but none blocks merging.

Verify that the 3-second timeout is sufficient for an API request with a 1 MB body limit.
The call also passes Effect.timeout("3 seconds"). The rest input accepts its own timeout field. Prefer that field when it covers the whole request. It then applies the same timeout semantics as other API calls.
This is a low-risk observation. The current code works.

Make the bare-name host fall back to GH_HOST, the same as the parsed path.

A bare repository name such as new-repo makes parseGitHubRepositorySelector return null. In that case, host falls back to the literal "github.com". The selector default at Line 1073 uses GH_HOST. A user who sets GH_HOST to an Enterprise host therefore creates a bare-name repository on github.com, under a credential for a different host. Use one default-host value for both paths.

Proposed fix

🟡 Minor · Resolve the base remote before fetching the pull-request ref. · GitHubCli.ts:915-1039

apps/server/src/sourceControl/GitHubCli.ts:915-1039 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Resolve the base remote before fetching the pull-request ref.
When no remote matches the base repository, baseRemote calls git.resolvePrimaryRemoteName. That helper selects origin when it exists. If origin points to a fork and the fork-head fetch fails, the fallback requests refs/pull/{number}/head from the fork. GitHub exposes that ref through the base repository, so checkout can fail even when the pull request is still reachable.

Suggested fix

2 const known = remoteFor(baseNameWithOwner);

🟡 Minor · A missing repository is reported as "Pull request not found". · GitHubCli.ts:203-204

apps/server/src/sourceControl/GitHubCli.ts:203-204 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A missing repository is reported as "Pull request not found".
fromGitHubApiError maps every GitHubApiNotFoundError to GitHubPullRequestNotFoundError. rest uses this mapper for all REST calls, so the mapping also applies to repository reads and writes:
readRepository calls repos/O/N for getRepositoryCloneUrls, getDefaultBranch, and the fork lookup in checkoutPullRequest.
createRepository calls orgs/ORG/repos.
If a repository name has a typo, or the org is unknown, the 404 surfaces with the message "Pull request not found. Check the PR number or URL and try again." GitHubSourceControlProvider copies error.message into detail, so the UI shows this wrong text.
Map the 404 based on the operation. For example, readRepository and createRepository can turn a 404 into GitHubCliCommandError with httpStatus: 404. Another option is a dedicated repository-not-found error.

Proposed fix (repository reads)

commandFailure hides the reason from users.

commandFailure puts the explanation only into cause. GitHubCliCommandError.message is the fixed text "GitHub request failed.". GitHubSourceControlProvider sends error.message to the user as detail. These conditions therefore all reach the user as the same generic text:

No GitHub remote exists (Line 632-635).
A repository selector is invalid (Line 1027).
A fork is gone (Line 933).

The repository rules say the message is "fixed or built from those attributes, never from cause". The rules also say a message that reaches the UI "is behavior, and a refactor keeps it".

Add a bounded attribute, such as a reason literal, or add a specific error class. Then build the message from that attribute.

As per coding guidelines: "Failures are Schema.TaggedError classes with structured attributes... The message is fixed or built from those attributes, never from cause".

Do not report a successful but undecodable /user response as a refused token.
The new branch now reports unknown for non-authentication failures. That covers most of the earlier review comment. Two gaps remain in the fallback branch:
If the /user request succeeds but decodeViewer returns None, login is undefined. The code then reports "GitHub refused the token". GitHub did not refuse the token in this case.
Line 173 puts viewer.failure.message into the user-visible detail. The guidelines say that attributes and messages must stay bounded.
Report a decode failure as unknown with a fixed detail.

Stop reporting every API 404 as "Pull request not found".

fromGitHubApiError maps every GitHubApiNotFoundError to GitHubPullRequestNotFoundError. rest also uses this mapper for repository operations:

readRepository through getRepositoryCloneUrls, getDefaultBranch, and checkout.
createRepository with orgs/<owner>/repos when the owner is not an organization.
createPullRequest on a missing repository or one the credential cannot see.

In each of these cases, the user gets "Pull request not found. Check the PR number or URL and try again." The real failure is a missing or inaccessible repository or organization.

Return GitHubPullRequestNotFoundError only from pull-request reads. For other operations, map a 404 to GitHubCliCommandError with httpStatus: 404, or to a repository-specific not-found error. One way is to let rest/graphqlJson take an onNotFound mapper.

Do not build GitHubCliCommandError.message from cause.message.

The getter returns this.cause.message when cause is an Error. The repository rules forbid this. GitHubCliCommandError wraps many causes:

commandFailure wraps text written for the message.
gitFailure wraps GitVcsDriver failures and FileSystem failures, such as readFileString of bodyFile.
fromGitHubApiError wraps GitHubApi errors.

GitHubSourceControlProvider sends error.message to the user as detail. Arbitrary git or platform error text can therefore reach the UI and RPC output. That text can include paths, refs, or command output.

Add a bounded attribute for the reason, for example a reason literal union or a separate error class per case. Build the message from that attribute. Keep the underlying error only in cause. For GitHubApiResponseError, a fixed message per httpStatus is acceptable, or a message from a bounded field that the API error class exposes.

As per coding guidelines: "The message is fixed or built from those attributes, never from cause, cause.message, or a stringified defect."

Normalize the host hint before parsing GH_REPO.

defaultHost uses the raw input.host. The remote path normalizes the same hint with apiHostForHint at Line 578. The SSH-alias test shows that a provider hint can be the alias github.

If GH_REPO=owner/name and the hint is github, the locator host becomes github. gitHubApiUrls then builds https://github/api/v3, so every request fails to resolve.
