Multi-Instance Scenarios Are Critical +**Mistake**: Ignored scope_filter in cache keys. +**Fix**: Added scope_filter to all cache keys. +**Lesson**: Always test with multiple plates, multiple windows, multiple users. + +### 4. Cache Invalidation Needs Explicit Rules +**Mistake**: Didn't specify when to clear caches. +**Fix**: Added explicit invalidation rules for all scenarios. +**Lesson**: "There are only two hard things in Computer Science: cache invalidation and naming things" - Phil Karlton + +### 5.
