T10: gatewayRPCError marks OPENCLAW_GATEWAY_SOCKET_CLOSED with retryable=true,
poll=true so the client degrades to "background/reconnecting" + keeps polling
instead of hard-failing (feeds App T5).
T11: runId-tagged warn logs at the tasks.get unconfirmed-fallback and
run-deadline-interrupt sites, so a runId can be joined across App→bridge→plugin→gateway.
T12: process-level stability counters (gatewaySocketClosed, taskGetUnconfirmedFallback,
runDeadlineInterrupt) exposed via /api/ping.metrics.
Revert S1 (default expectedArtifactDirs): it set requiresExport=true / default dirs
for any artifact-inferring task, which made a gateway run that succeeds with NO
artifact hang "waiting for artifact export" (TestHTTPHandlerGatewayOpenClawHandlesFive
ConcurrentE2ECases + ...WithoutPromptHeuristic went red). The blocking is tied to
expectedArtifactDirs presence in openClawTaskGetRequiresArtifactExport; decoupling
scan-hint from block-on-export needs a careful, separately-tested change. Reverted to
keep main green; S1 to be redesigned (see docs/cases/06 §7).
Full internal/acp suite green.
