- Filter out debug noise (plan-B per-path lines, heartbeats, timing stats, telemetry) - Strip server-side nanosecond timestamp prefix from displayed messages - Transform snapshot progress lines to show current path instead of doc count + ETA - Humanize recurring message patterns (plan-B summary, prefetch, snapshot total) - Raw collect.log and raw_export.json are unaffected Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
