+## Substantive work
+
+**9 Copilot table-prefix-misread FP threads resolved batch** on #4286 (8) + #4288 (1). All same known-FP class per `blocked-green-ci-investigate-threads.md` "Suspect-by-default" catalog. Each shard's first line IS canonical 6-column pipe-row; Copilot misreads PR-diff line-number rendering as line content. Single combined explanatory comment per PR.
+
+**Batch this tick** = 4 local shards (0038Z-c + 0039Z-c + 0040Z-c + this 0041Z-c) → 1 PR. Cost-aware: 1 GraphQL push instead of 4.
