+# Domain Docs
+
+How to consume this repo's domain documentation when exploring the codebase.
+
+## Before exploring, read these
+
+- **`CONTEXT.md`** at the repo root - the domain glossary and orientation.
+- **`.agents/adr/`** - read the Architecture Decision Records that touch the area you're about to work in.
+
+If any of these files don't exist, proceed silently. Don't flag their absence or suggest creating them upfront; they are created lazily when terms or decisions actually get resolved.
+
+## File structure

+
+## Use the glossary's vocabulary
+
+When your output names a domain concept (an issue title, a refactor proposal, a hypothesis, a test name), use the term as defined in `CONTEXT.md`. Don't drift to synonyms the glossary avoids.
+
+If the concept you need isn't in the glossary yet, that's a signal - either you're inventing language the project doesn't use (reconsider), or there's a real gap (note it).
+
+## Flag ADR conflicts
+
+If your output contradicts an existing ADR, surface it explicitly rather than silently overriding:
+
+> _Contradicts ADR-0001 (...) - but worth reopening because..._
