Environment and collection sync issue with firebase

Editor assessment

`fix: environment and collection sync issue with firebase` names the affected features and the backend but `sync issue` is too compressed to know what failed — writes dropped, reads stale, order wrong — so the substance sits behind the diff. No scope marks the store or firebase area. No body supplies the symptom or the mechanism, which is what a fix message should record. Style basics hold: imperative verb, no period, no junk. Valid and directionally understandable, but thin — mediocre teaching value.
