Knowledge Bases
Curated corpora—wikis, tickets, PDFs, APIs—governed for ingestion, access control, and freshness as RAG source of truth.
Why it matters
- Garbage in remains garbage out regardless of model size.
- ACL sync is a security requirement, not optional.
- Ownership and SLAs differ from generic vector dumps.
Key ideas
- Source governance
- Freshness SLAs
- Permission mirroring

Contextual retrieval
Why this resource. How chunks should carry enough context to be reusable knowledge.

- contextual retrieval
A knowledge base is more than an index—it defines authoritative sources, update cadence, redaction rules, and who may read which chunk. Connectors should respect deletes and permission changes intraday. Document owners approve inclusion tiers (customer-facing vs internal). When answers fail, check corpus gaps before blaming prompts. Assign corpus owners with OKRs on freshness and coverage; orphan wikis become silent RAG enemies within quarters.
