main's production resolver with the contributor's regression tests: 5 failed, 12 passed (34 skipped). alias API host was github.com-scale instead of github.com; marked origin lost precedence.

review repair: strengthened the existing mixed-transport test with distinct repository paths and a marked HTTPS origin. it failed before the repair. selector normalization always uses the SSH alias API host, and fallback accepts a recognized remote only on its API host. The existing mixed test now covers marked and unmarked origins, explicit and absent hints, and both remote orders; the unmarked variant also failed before its repair.

blacksmith-check, final source: vp run check:changed passed format, lint, both knip checks, generated GraphQL check, typechecks for 10 affected packages/dependents, and all 51 tests across the 2 existing resolver/provider files. 3 existing GitManager tests for non-origin lookup and same-repository upstream restoration also passed on the final source. no new test files.

live Linux runtime: production GitHubSourceControlProvider, GitHubRest, GitHubRequestPolicy and GitHubCredentials with real Git subprocesses and authenticated GitHub REST/GraphQL. temporary repository has marked alias origin pingdotgg/t3code plus different upstream octocat/Hello-World. both git@github.com-work and ssh://git@github.com-work:22 resolve to github.com/pingdotgg/t3code, read default branch main, and read PR 22246. no network Git fetch/push via SSH was tested.

no UI components, render paths, contracts, or credentials interfaces changed. native desktop/mobile, remote connection modes and write operations remain unverified. no browser evidence applies to this server-only resolver change.

review limit: both independent GPT-6.1-Sol reviewers identified the unmarked mixed-transport case in the permitted follow-up. It was reproduced and repaired as above. No further review round was requested; final-head independent approval remains unverified.
