What's changed

Improvements

• Retry TASK_MIDDLEWARE_ERROR under the task's retry policy instead of failing the run on the first attempt. The error was already classified as retryable by shouldRetryError, but shouldLookupRetrySettings did not include it, so the retry flow fell through to fail_run. Fixes #3231. (#3676)

Bug fixes

• Fix TypeError in unflattenAttributes when the input attribute map contains conflicting dotted key paths (e.g. both a.b set to a scalar and a.b.c set to a value). The path-walk loop now applies last-write-wins when a prior key wrote a primitive, null, or array at an intermediate slot, matching the existing precedent in AttributeFlattener.addAttribute. Callers no longer crash when handed malformed external attribute inputs. (#3762)
• Fix external trace context leaking across runs on warm-started workers with processKeepAlive enabled. Every subsequent run's attempt span was being exported with the first run's traceId and parentSpanId, breaking causal-chain navigation in external APM tools. Runs without an external trace context are unaffected. (#3768)
