+name: Syncro — verify appointment date day-of-week
+description: Before creating any Syncro appointment, verify the computed date falls on the intended weekday (py datetime) and show the day name in the preview. Wrong-day incident #32312 2026-05-21.

+# Syncro — Verify appointment date day-of-week before creating
+
+**Rule:** Before creating any Syncro appointment, always verify that the computed date
+actually falls on the intended day of the week.
+
+**Why:** Day-of-week math is easy to get wrong. In the incident that prompted this rule
+(2026-05-21, ticket #32312), "Saturday" was computed as May 24 — which is actually a Sunday.
+The appointment landed on the wrong day and didn't appear where Winter expected it on the calendar.
+
+**How to verify:**
+
+Use Python or Bash to print the weekday before including it in the preview:
+
+```bash
+py -c "import datetime; d = datetime.date(2026, 5, 24); print(d.strftime('%A %Y-%m-%d'))"
+# Output: Sunday 2026-05-24  ← would have caught the error
+```
+
+Or include the day name in the TICKET PREVIEW and require explicit user confirmation
+that the day-of-week matches their intent.
+
+**Catch:** Always show `Day YYYY-MM-DD` (e.g., "Saturday 2026-05-23") in the preview —
+never just the numeric date — so the user can verify at a glance.
