Base-chain ecosystem news for Base-native agents, not the general crypto firehose.

Base-chain ecosystem news for Base-native agents, not the general crypto firehose. Up to 12 Base-scoped headlines from the last 48h, each with its own permalink and publication timestamp, screened against the general /crypto-news feed; `screen` states what was dropped. The AI topic read is optional and is withheld, never padded with macro, when there is no Base coverage. Refreshed hourly from cache; a read past the freshness window pulls inline.
