01
What is a causeway, in this context?
+
A causeway is a road built across a body of water. In Causeway-the-platform, it is the paved path from raw data in the lake to a governed, contracted dataset that downstream can trust.
02
Do I have to move my data?
+
No. Causeway sits over your existing lake or warehouse (Snowflake, Databricks, BigQuery, Iceberg) and governs in place. You declare contracts on tables you already have.
03
What happens when a contract breaks?
+
Downstream consumers are notified, the dataset is marked Broken Contract in red, and stewards are paged. Promotions to Gold are blocked until the contract is healed.
04
How does RAG classification work?
+
Three tiers: Restricted (mask or redact PII), Internal (no exports), Public (no masking). Every dataset carries one tier. One masking policy per tier. We deliberately refuse a taxonomy of fifty.
05
Can Causeway govern AI use of my data?
+
Yes. Each dataset declares per-right consent for RAG retrieval, fine-tuning, and external LLM token export. Violations pause model training in the affected region.
06
Is Causeway open source?
+
The contract spec and lineage protocol are open. The platform itself is a commercial product; pricing is per million rows governed, with volume tiers.
