  "explanation": "Standards-axis review is clean: no actionable hard violations or evidence-backed heuristic smells found. The new aggregation uses the existing poison-recovering lock convention (KNOWN-HAZARDS §7.33), releases its shared counter lock before emission, preserves exceptional/role attribution and first-write timestamps, and leaves the bounded-write retirement machinery intact (§7.38). Retained session polling follows the existing broker request/reply dispatch and discards failed carriers rather than supplying false empty liveness. Trace tags accompany production code, behavioral socket regressions and documentation, with the new requirement scoped in the manifest. No tests, builds or runtime validation were executed, as instructed.",
