Fixes: #19523
Summary (draft)
Implement usage count filtering via counter caches:
device_countto DeviceType andmodule_countto ModuleType usingCounterCacheFielddevice_count__gte=…,deviceCount: { gte: … }).device_count) as discussed; introducemodule_countfor consistency.Note on receivers (included so CI passes on
feature)This draft includes the per‑sender
dispatch_uidchange toutilities.counters.connect_counters()to prevent duplicate signal registration (see #20697). I’ll rebase/drop this once #20697 merges tomain.Status
Tests are pending! Opening as a draft to validate the approach and naming before finalizing.
