The C1 fix (a45db52) shipped with no committed test: the defect lives in js/, and this repo has no JavaScript test surface - no package.json, no eslint config, no tsconfig - so nothing in CI could notice a reinstatement of the false "default channel" message. ruff covers only Python. Rather than add a JS toolchain, the guard shells out to `node` and drives the SHIPPED client modules (CustomNodesManager.installNodes, uninstallNodes) through a stubbed 404, then reads the string that reached app.ui.dialog.show() - the sink the user actually reads. Only the network and the browser are stood in for; the client code that runs is the real file, reached through a symlink under --preserve-symlinks so nothing is copied. The same predicate runs against both arms, so this is a guard rather than a tautology: it must pass on the current client and FAIL on the client as it was at 14de630, on the false lead specifically. Verified by mutation too - reinstating either 404 branch turns both GREEN nodes red. Every node skips with a reason when `node` is absent, so a node-less runner is not broken by this file.
The stub auto-clicks the confirm button so customConfirm() resolves headlessly, but had no branch for "did not match". A reworded button would leave the client waiting forever and node would run to the caller's 120s subprocess timeout, surfacing as TimeoutExpired with a traceback - a multi-minute mystery instead of a diagnosis. Report and exit non-zero instead, naming the buttons that were seen and where to update the pattern. The branch is guarded on there being buttons at all: the ordinary error-path dialog has none, and firing on that would break every capture. Also correct what the predicate's comments claim. The two false-lead patterns name the regression that already happened; they are not what makes the guard general. Any substitution displaces the server's own text, so the server-body clause is what catches a reworded revival - the patterns alone would not.
📝 WalkthroughWalkthroughAdds headless browser stubs and a Node harness for simulated 404 responses. Adds Python tests for current and pre-fix batch install and uninstall clients. Tests verify that dialogs show the server error and omit false security-level messages. ChangesBatch 404 dialog regression coverage

Add a required CI test job
The repository has no CI job that runs pytest, and no workflow provisions Node.js. Add a required job that installs Node.js and runs pytest tests/test_batch_404_dialog_guard.py; otherwise the guard remains skip-only.

Adds a regression guard for the issue #3128 C1 fix landed in #3161: on a batch install/uninstall 404 the client must surface the server's real reason, not the false "default channel" message.
tests/test_batch_404_dialog_guard.pydrives the realjs/dialog path through a small Node DOM harness (no browser) and asserts the rendered error contains the server body and never "default channel".main(4 passed).Tests-only; no production change. Follow-up to #3161.
