+# knowledge_harvest_pattern — v1
+
+**Why this iteration:** Lifted verbatim from `conductor/code_styleguides/knowledge_artifacts.md` §"0. The one-glance directory layout" (lines 9-26) + §1 (lines 28-44). This is the baseline encoding — the directory-tree-plus-rationale style currently in production.
+Future variants will test alternative encodings (rule-only, table-only) against this baseline.

+- The MCP dispatch uses a flat if/elif chain. 4 places, 45 tools. [from: 2026-05-12-investigate-dispatch, 2026-05-12]
+- ai_client.py has 5 separate per-provider history lists, each with their own lock. Switching providers mid-session loses history. [from: 2026-05-13-state-mutation-matrix, 2026-05-13]
+- RAG is opt-in. Default-off in new projects. [from: 2026-06-12-rag-discipline, 2026-06-12]
