eth_getFilterLogs on Avalanche
Returns all logs matching a filter created with eth_newFilter. A heavy, stateful method — needs a free API key.
Returns the whole backlog for a filter id in one shot — as heavy as eth_getLogs. Filters are node-local and expire when idle, so a stale id returns 'filter not found'; re-create it and retry.

Logs & events on Avalanche
Logs cover the C-Chain only — activity on Avalanche L1s/subnets never appears here. Log density is moderate; windows of tens of thousands of blocks are practical with filters.
