KYE™ framework adapters
Thin wrappers so popular agent / RAG / data frameworks emit the KYE™ §0.3 governance + evidence envelopes for free. Each adapter reuses the SAME envelope shape as the Agent Dev Kit™ templates (§32) — KYE™ governs the framework as a principal (§0.30); it never runs, replaces, or vendors it. The non-competition lock vs LangChain / LlamaIndex / CrewAI / Firecrawl / CocoIndex is permanent.
langchain
A BaseCallbackHandler that emits the governance + completion envelopes around every LangChain chain / agent run.
llamaindex
A retrieval callback that seals each LlamaIndex query / retrieval as a KYE™ tool-call inside the evidence chain.
crewai
A step callback that binds a CrewAI crew at kickoff and records each agent task as a KYE™ tool-call.
firecrawl
A scrape wrapper that seals each Firecrawl crawl / scrape as a KYE™ tool-call with the source URL pinned.
cocoindex
A flow hook that records each CocoIndex transform / index update as a KYE™ tool-call in the evidence chain.
haystack
KYE™ Authority Components for a Haystack pipeline — a signed agent manifest, a tool-call admissibility gate that runs the real tool only on allow, sub-agent attenuation, a RAG reliance record, and an evidence pack. The framework decides what to do; KYE™ decides whether it was allowed to.
pgvector
A retrieval Data-Admissibility gate that sits in front of a customer's pgvector query and binds retrieved context to purpose + authority before it feeds an agent action. Retrieval is not authority; recall is not a mandate.
