Summary

ACP sessions never receive document RAG configuration because with_document_config() is not called in src/acp.rs.

Root Cause

DocumentConfig::default() has rag_enabled = false. Since src/acp.rs omits agent.with_document_config(config.memory.documents.clone()), document RAG injection is silently disabled for all ACP sessions regardless of TOML settings.

Comparison:

• src/runner.rs:826 — agent.with_document_config(config.memory.documents.clone()) ✓
• src/acp.rs — missing ✗

Related: #1633 (graph config also missing in ACP).

Fix

Add after the memory-related with_* calls in the ACP factory function:

agent = agent.with_document_config(app.config().memory.documents.clone());

Severity

Medium — RAG injection into agent context is user-visible if rag_enabled = true in config.
