      # this advisory was cleared: #4030 (16 Zod/registry reds, lossless restore) and
      # #4063 (the last red — the LiveWS boot test — root-caused as a real event-loop
      # stall in the WS sidecar, fixed + relocated to the integration suite). A full
      # ci.yml run on release/v3.8.28 then showed all 8 unit shards green, so PR->release
      # now blocks on unit-test regressions in the impacted set (typecheck:core already
      # blocked above). Fail-safe still runs the FULL unit suite on hub/unmapped changes.
