Analyzed 4 functions across 2 files. (1 skipped: 1 too large.) Full details: Cmux User-Facing Error PrivacyExplanation The diff adds user-facing diagnostics that echo the original invalid argument. Resolution Do not include raw arguments or positionals in browser-profile validation errors. Return a localized generic unexpected-arguments diagnostic, or otherwise redact secret-bearing values before formatting the message. Apply this to both unknown-option and surplus-positional validation paths.

Review: adversarial pass on the diffVerdict: LAND. The strongest tests of your five. These are integration tests that spawn the bundled CLI against a mock socket, so they pin the production call sites rather than a helper, which is exactly the difference that makes #15978 weak.

- Around line 16600-16605: Update runBrowserCommand to parse browser option
values, the `--` separator, and mutation operands once before extracting
options, then use that parsed result for the delete branch instead of rebuilding
`profileArgs` from already-consumed tokens. Add a process-level test verifying
`cmux browser profiles delete --surface --typo Work` fails without sending a
socket request.

Fix the locale for the English error assertion.
The CLI localizes "unexpected arguments". Set AppleLanguages to (en) for this child process so the assertion does not depend on the test runner's locale.

Follow-up on the maintainer review: browser-profile mutation commands now validate the original argv shape before extracting options, so unknown flags / missing values cannot be silently consumed and forwarded to the socket. The existing no-request regressions remain in place. Current infra/CLA checks are green; ready for re-review when convenient. |

Centralize browser-profile mutation parsing.
The pre-socket validator receives the same commandArgs that runBrowserCommand receives. Both paths strip display flags, extract the surface, normalize aliases, and apply the same mutation rules. Shared helpers already remove low-level parsing duplication, but each path still constructs its own mutation operands and RPC parameters.
The current code does not establish a reachable delete command that targets different profiles. The issue is architectural duplication, which violates the rule requiring one shared action path and can regress when only one branch changes.
Make parseBrowserProfileMutation(command:commandArgs:) throws -> BrowserProfileMutation the source of truth. Use its result for pre-socket validation and RPC parameters. Start with the delete branch, then migrate the remaining mutation branches. Add no-socket parser tests.

Summary
Fixes #15729.
Browser profile mutations previously parsed known options and then used a non-flag filter, which silently dropped unknown flags and in several forms ignored extra positionals.
This change:
--as a real terminator so a literal profile name such as--literal-profileremains valid;--all/--forcescoped toclearonly;The regression test commit precedes the implementation.
Testing
Added process-level coverage that malformed create/rename/clear/delete commands fail before reaching the socket, plus a positive
--terminator case.I could not run the macOS bundled CLI suite from this connector environment, so exact-head CI remains the execution gate. No local pass is claimed.
Changelog
Fixed browser profile mutation argument validation.
