Review comments at @apps/desktop-tauri/scripts/proof-check.mjs:
- Around line 187-191: Update CDPClient.send to give each pending request a
timeout and clear it when the request resolves or rejects. Also handle the
socket close event by rejecting all pending requests and removing them from the
pending map, so proof:check exits rather than hanging when the browser stops
responding.
- Around line 141-156: Remove the stale DevToolsActivePort file before spawning
the browser so the polling loop cannot attach to an earlier instance. In the
browser launch flow around spawn and the portFile polling loop, also detect if
the spawned child exits before opening the debugging port and report a
profile-lock error.
Review comments at @apps/desktop-tauri/src/proof/router.ts:
- Around line 186-196: Update the fixture-builder handlers in the proof router
to use the current settings patched by update_settings, rather than the stale
scenario.settings. Add a current-scenario helper that combines scenario with the
local settings, then pass it to providerSummaries, providerDetail,
providerChartData, and usageSpendSummary; keep get_cached_providers using
enabledProviders.

`child.once("exit")` to also handle the `error` event emitted when `spawn()`
cannot launch the browser. Route the actual launch error through the existing

Review comments at @apps/desktop-tauri/scripts/proof-check.mjs:
- Line 418: Before sending Target.closeTarget in the cleanup flow, check whether
the CDP socket is still open and skip the request if it has closed. When CDP is
closed, immediately kill the launched browser rather than waiting on further
cleanup requests; locate this behavior around the cdp and targetId cleanup
condition.
Review comments at @docs/WINDOWS_PROOF.md:
- Line 228: Update the remote CDP documentation beside the `--cdp` workflow to
explain that CDP has no authentication: keep the endpoint bound to loopback and
access it through an SSH tunnel or authenticated bridge. Recommend attaching
only to a dedicated browser profile without sensitive session data, and clarify
that `--cdp` does not apply `.proof/browser-profile` because it attaches to an
existing browser.
