+Non-breaking changes:
+- Include PAYG slots in MaxSlots guard — the reservation manager now counts existing + PAYG-created slots before allocating blind-scheduler slots, preventing total slot counts from exceeding `MaxSlotsPerCommitment` ([#987](https://github.com/cobaltcore-dev/cortex/pull/987))
+- Use public Limes endpoint in knowledge datasource — fixes HTTP 400 errors after Limes enforced domain name matching on `Host` headers ([#999](https://github.com/cobaltcore-dev/cortex/pull/999))
