+## Update: 18:58 PT (2026-06-27) — scratch-file cleanup
+
+Two empty scratch files (`.hours_calc.sh`, `.lab.txt`) had been swept into a repo-root commit
+(ab0f0e0) by the catch-all `git add -A` during an earlier sync. They were removed in commit
+8633d59 (2026-06-26 17:20) and are confirmed absent from the HEAD tree. No functional impact;
+noted as a reminder to keep scratch in the scratchpad dir, not the repo root.
