+# Live Verdict — 2026-07-27-eval-friction-c1-third-clean-window
+
+- Verdict: `keep_observe`
+- Phenomenon: The current every-3d friction window from 2026-07-24 03:00 UTC to 2026-07-27 03:00 UTC produced no friction signals, no actionableCandidates, and no referenceOnly clusters. The latest archived predecessor, 2026-07-18 03:00 UTC to 2026-07-21 03:00 UTC, was also empty, while the intervening 2026-07-21 03:00 UTC to 2026-07-24 03:00 UTC window is still pending archival in evidence PR #95 and is therefore treated here as an observation gap rather than archived no-friction evidence.
+- Harness: F245/friction-rollup (friction rollup (Top-N + sensorForm))
+- Root cause: No persistent root cause is observable in the current window. The earlier singleton still looks more like a transient translation_gap or execution_gap than an active recurring harness, tool, or environment defect. (confidence low)
+- Owner ask: Keep the every-3d friction rollup running and only escalate if a future 72h window surfaces any actionableCandidate, any recurring referenceOnly eval-domain cluster, or any repeated non-eval-domain cluster.
+- Re-eval: next eval at 2026-07-30T03:00:00.000Z
+
+Evidence:
+- snapshot:bundle/2026-07-27-eval-friction-c1-third-clean-window/snapshot
+- attribution:bundle/2026-07-27-eval-friction-c1-third-clean-window/eval-F245-2026-07-27:no-finding
+- metric:friction-rollup.cluster_count
+- metric:friction-rollup.top_cluster_count
+- metric:friction-rollup.tail_signal_count
+
+Counterarguments:
+- The current window is quiet, but the unmerged 2026-07-21 03:00 UTC to 2026-07-24 03:00 UTC evidence leaves an archival observation gap, so the repo still does not show an uninterrupted three-window quiet streak.
+- The earlier singleton came from a specific workflow, so the archived calm may reflect topic churn rather than durable recovery.
+- If the next window reintroduces even one repeated cross-channel cluster, the current no-finding interpretation should be revised quickly.
