Module utils/SupplierStatsStore

Increment search query count (called once per supplier at start of execute())

Increment successful HTTP connection count (HTTP 2xx, non-cached)

Increment failed HTTP connection count (HTTP 4xx/5xx, network errors, non-cached)

Increment unique product count (called when a non-cached product detail is fetched)

Increment parse/processing error count (called when product processing throws)

Read all stats from IndexedDB, returning the SupplierStatsData shape: { [dateKey]: { [supplier]: SupplierDayStats } }. Recording runs in every build; only the stats UI is gated (dev builds, or advanced mode).

Clear all stats — removes all records from the supplierStats store.
