… eagerly. - Read path: when a cached straggler result exists, serve it directly instead of always fanning out to the deadline-bound worker Map/Reduce path. - Compute eagerly on session creation off the request critical path and cache the result (gated by a flag, default off). - Stop registering the smart-suggestion barrier-cores rule so its per-request straggler detection no longer runs.
