 ## Repo boundary
 
-This repo owns **llm-connect** — the multi-provider LLM client library — only.
+This repo owns **llm-connect** only. It does not own:
 
-It does NOT own:
-
-- **API key storage / secret management** → caller's environment (env vars,
-  key files, vault). llm-connect resolves keys but does not store them.
-- **Consumer routing logic** → `inter-hub/AgentBridge.hs`, `markitect` etc.
-  `RoutingPolicy` (WP-0003) provides primitives; policy data belongs in the consumer.
-- **The Claude Code CLI binary** → installed separately; `ClaudeCodeAdapter`
-  shells out to it.
-- **markitect application code** → `markitect.llm` is a shim that re-exports
-  from here; all implementation lives in this repo.
-- **State hub / custodian infrastructure** → `the-custodian/state-hub/`
-- **IHF bridge scripts** → `inter-hub/scripts/llm_bridge.py` lives in inter-hub,
-  not here. llm-connect is a dependency of that script.
+<!-- TODO: List what belongs in adjacent repos, e.g.:
+- SSH key management → railiance-infra/
+- State hub code     → state-hub/
