Inline comments:
In `@pkg/machinediagnostics/locator.go`:
- Around line 113-136: Update ReadActive to build candidate paths with
ActiveLocatorCandidates and delegate outcome selection to
readActiveFromCandidates, removing its separate candidate-state branching.
Preserve the existing error return if candidate path construction fails.
- Around line 138-147: Update ReadActive to handle UserRuntimePaths cache lookup
errors by continuing with the system locator candidate instead of returning
early, preserving its stale-response and system-only not_initialized behavior.
Leave ActiveLocatorCandidates unchanged unless its callers also need this
fallback.
In `@pkg/machinediagnostics/runtime_paths_test.go`:
- Around line 40-47: Update TestEnsureRuntimeDirKeepsUserRuntimePrivate to
assert that the directory has no permission bits outside 0o750, rather than
requiring an exact mode that can be reduced by the process umask.
In `@pkg/machinediagnostics/store_test.go`:
- Line 220: Update the both-missing test around readActiveFromCandidates so it
uses only the supplied temporary candidates and cannot consult the host’s
DefaultLocatorPath. Keep the assertion that the resulting Availability is
AvailabilityNotInitialized.
- Line 193: Update the “system wins” and “stale system falls back”
candidate-selection assertions to use distinct asserted values for the system
and user stores, so each test verifies which candidate was selected. In the
stale-fallback case, also assert that the response freshness is FreshnessFresh.
In `@pkg/tunnel/local_listener_test.go`:
- Around line 84-85: Update the listener-closure polling logic around
net.DialTimeout to treat only ECONNREFUSED as closure; fail on other non-timeout
dial errors and continue polling on timeouts.

Do not make the private-directory assertion depend on the process umask.
EnsureRuntimeDir(dir, false) calls only os.MkdirAll(path, 0o750), and the umask filters that mode. If the umask is 077, the directory gets mode 0o700, and require.Equal(..., 0o750, ...) fails even though the directory is correctly private. Assert that no permission bits outside 0o750 are set.
💚 Proposed fix
info, err := os.Stat(dir)
require.NoError(t, err)
- require.Equal(t, os.FileMode(0o750), info.Mode().Perm())
+ require.Zero(t, info.Mode().Perm()&^os.FileMode(0o750), "user runtime dir must not be world-accessible")📝 Committable suggestion

Make candidate-selection assertions distinguish the candidates.
Both candidates report DaemonRunning in “system wins” and “stale system falls back.” Those assertions pass even when the selector returns the wrong candidate. Give the system and user stores distinct asserted values. For the stale case, also assert FreshnessFresh. (raw.githubusercontent.com)

Isolate the “both missing” result from the host locator.
When both temporary paths are missing, readActiveFromCandidates reads DefaultLocatorPath. If that locator exists on the test host, this assertion can fail despite both test candidates being missing. Make the selector return a not-initialized response from the supplied candidates instead of reopening the host locator. (raw.githubusercontent.com)

Require connection refusal before reporting listener closure.
If the test process exhausts file descriptors, net.DialTimeout can return EMFILE while the listener remains open. This branch treats that non-timeout error as closure. The cancellation or health-check test can then pass before shutdown occurs. Return only for ECONNREFUSED; fail on unrelated dial errors and keep polling on timeouts. (go.dev)
