@@ -83,7 +83,6 @@ Outstanding, roughly by impact on reaching a wrong conclusion:
 - **`gh`/`glab` execute on the client** for SSH repos (`src/main/github/github-repository-identity.ts:41-52`, `src/main/gitlab/gitlab-project-ref-resolution.ts:245-256`). PRs are authored by the client's GitHub identity, the client's rate limit is spent, and the PR body is written to the client's tmpdir. Moving this to the execution host needs a new relay RPC surface — the relay has no `gh.*` method today.
 - **`doResetRelay` marks every lease `expired` in a `finally`** (`src/main/ipc/ssh.ts:1393-1399`). The code carries an explicit rationale at `:1401` — reset force-kills the relay, so local handles are stale "even if the reset command failed after SIGTERM." That rationale is sound for its stated case but does not cover the case where the command never ran at all (transport failure), where the client records a termination that never happened.
 - **Windows relay-install GC** treats 200 ms of pipe silence as proof the relay `exited` and deletes its directory (`src/main/ssh/ssh-relay-versioned-install.ts:355-361`). The sibling exception path already fails closed correctly.
-- **Unknown remote platform falls through to POSIX hook installation** (`src/main/ssh/ssh-relay-session.ts:1281-1288`); `:1292` hardcodes `linux` for all non-Windows remotes, including macOS.
 - **Shared symlinks, `orca.yaml` shared directories, and `.worktreeinclude` are silently skipped** for SSH worktree creation (`src/main/ipc/worktree-remote.ts:1885`).
