📝 WalkthroughWalkthroughThe v2 capability list now includes additional socket method names. The heartbeat test expects the expanded set. A new guard compares public dispatcher methods with advertised capabilities, and CI runs the guard. ChangesSocket v2 capability discovery
Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~20 minutes Change: Bug fix · Severity of issue fixed: Medium Merge Risk: 🔵 Low · up to The expanded capability catalog has no demonstrated runtime defect. Merge is reasonable with follow-up to execute the regression tests and protect the three advertised mobile methods against future omissions. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The expanded method list does not itself grant additional permissions. The main concern is an inconsistent public-support contract: three newly advertised terminal-control methods are also classified as intentionally internal. Retained concerns

- Line 1184: Update the dispatcher capability coverage test to compare the
complete dispatched method set with v2Capabilities(), using an explicit
allowlist for intentionally hidden methods. Keep expectedMethods checks as
appropriate, and ensure any dispatched method missing from both the capabilities
and expected set causes the test to fail.

Review comments at @scripts/check-socket-capabilities.py:
- Line 44: Update switch_cases in the socket-capability check to extract every
quoted pattern from compound case labels, including comma-separated and
multiline labels, rather than only the first; add a fixture where only the
second pattern is missing and verify the guard reports it.
- Line 79: Update the public-method selection in the parity guard to compare all
methods in dispatched, excluding only an explicit, commented list of internal
methods, rather than filtering by PUBLIC_PREFIXES. Keep the comparison aligned
with every reachable CLI-facing dispatcher method, including auth.status.

test_ci_socket_capability_guard.py so direct Python invocation runs
test_public_dispatcher_methods_are_advertised,
test_compound_case_labels_are_all_checked, and
test_compound_case_reports_missing_second_label. Keep the existing CI command
usable without relying on pytest.
Review comments at @scripts/check-socket-capabilities.py:
- Line 80: Remove the exclusions for mobile.terminal.mouse,
mobile.terminal.paste_image, and mobile.terminal.scroll from the parity check in
check-socket-capabilities.py so these advertised methods are included in the
comparison.
