* perf(startup): stop an unreachable SSH host from gating local terminal restore
An asleep or unreachable SSH target held the terminal-restoration gate for the
full 15s reconnect timeout, so no terminal restored — local ones included.
Startup now awaits only the target that owns the active workspace's tabs and
lets the rest connect in the background, folded into the existing deferred path
that reattaches their PTYs on tab focus.
Also splits the renderer's git-environment fence out of the first-window PTY
services barrier: worktree hydration needs shell-PATH generation and the managed
WSL CLI registration, not a daemon PTY spawn or a hook-server bind. Terminal
restoration still fences on the first-window services via
app:prepareTerminalStartupRestoration.
Measured with tests/tools/benchmarks/startup-time-bench.mjs (382 restored tabs,
28k-file profile, medians of 3):
unreachable SSH host: 17.27s -> 1.34s to renderer-startup-hydration-done
all-local: 1.98s -> 1.33s
* fix(startup): restore the startup-ordering oracle and keep a connected background SSH target undeferred
app-startup-routing.test.ts pinned the old step names, so the two ordering cases
went vacuous-then-red when the barrier split. Repoint them at the steps that now
carry the same fences: 'git-environment-barrier-await' (shell PATH + managed WSL,
the fence host Git needs) before hydration worktrees, and
'prepare-terminal-startup-restoration' (which awaits firstWindowStartupServicesReady
in main) before terminal reconnect. Both still fail against main's hydration source.
Also: the timed-out-eager rewrite of the deferred list re-added background targets
that had already connected, undoing removeDeferredSshReconnectTarget and sending
fresh panes on a reachable host down the cold-restore path.
PR 9501 shipped real-home routing for the host system default, and the
env override that could turn it back off was never a shipped control. The
managed-account half of the shared runtime mirror has been unreachable
since: every host account routes to its own self-contained CODEX_HOME
before that code runs.
Delete the flag module and its env plumbing plus the managed branch of
syncForCurrentSelection and the six helpers only it called. The three
lanes that still use the shared mirror -- Windows, a custom CODEX_HOME,
and a hook-lane gate that reports unusable -- are untouched, as are every
legacy migration and the WSL read-back helpers.
Remove one-off incident docs and committed test-results noise, move
dev/repro/bench tools under tests/tools, and relocate i18next config
into config/ so the GitHub root scrolls to the description faster.
