ATCO trainers: How are you handling recency tracking for 2015/340 audits?

ANSP/ATO instructors and compliance folks: How do you handle controller recency proof during EU 2015/340 audits?

Spreadsheets? Custom software? Manual logs? Success stories or horror tales?

Specific pains I’m hearing:

•	Rostering that breaks under scrutiny

•	Missing sim session evidence

•	Safety findings without training closeout

What’s your setup? Tools? Workarounds? (Aviatioin LMS builder here collecting real feedback, no sales pitch.)

TIA for battle-tested advice.
