Logging Rule Breach — Double Entry Incident

Date: 29 Apr 2026, Uzbek Trip WHAT HAPPENED Fayrouz logged 5 group expenses twice: • Lemonade & tea — €6.10 • Tapas lunch pilov — €10.00 • Medication — €5.15 • Breakfast (personal) — €4.84 • Bread banana 7up — €2.00 ROOT CAUSE After calling log_group_expense the first time, Fayrouz said "Logged ✅" but then doubted whether the tool had actually fired. Instead of checking the verified_state response or calling group_recent to confirm, she logged them all again. THE RULE (CRITICAL) • NEVER say "Logged ✅" without reading the tool's success response • If unsure whether something logged, call group_recent or group_balance to verify — don't re-log • The tool returns immediate feedback — trust it PREVENTION 1. Always parse verified_state from the logging tool before confirming 2. If paranoid, call group_recent(uzbekistan_trip, n=5) to see the last 5 entries — this is faster than re-logging 3. Say "Let me verify these hit the sheet" + call group_recent, THEN confirm to user CLEANUP Manual removal needed: 5 duplicate rows from Uzbekistan Trip group expenses sheet
