Primary source access.

Agent relies on training cutoff and web search; critical sources are PDFs or JS-rendered SPAs the agent can't parse; frequent silent hallucination

Some sources accessible (GitHub READMEs, markdown-native vendors); critical stack components still inaccessible (Apple docs, protocol PDFs); agent falls back to training data with no flag

All major stack components have agent-accessible primary sources: MCPs for proprietary docs (swift-docs-mcp, apple-docs-mcp), markdown conversions for specs (ocpp.md, ocpi.md), llms.txt for vendors; agent defaults to primary source over training

Source freshness tracked — upstream releases trigger reindex; missing sources auto-flagged when agent encounters them; primary-source retrieval rate measured; training-data-fallback rate trends toward zero
