+# Hulumath AI Working Agreement
+
+Read `context/boot.md` and `context/capsule.json` before changing the product.
+Then select the smallest relevant product, architecture or deployment
+document under `docs/`.
+
+## Source Boundaries
+
+- Hulumath owns its Django application, mathematical content, product rules
+  and release documentation.
+- JLearn may link to Hulumath but does not own its users or runtime data.
+- JOps owns shared edge, deployment observation and platform authentication
+  facts.
+- Secrets, production databases, uploads and user data remain outside Git.
+
+## Change Protocol
+
+1. Preserve server-side authorization, scoring and anti-cheat checks.
+2. Keep API and WebSocket routes backward compatible or version them.
+3. Update product or deployment documentation with behavioral changes.
+4. Run `make context-check`, `make check` and `make test` before committing.
+5. Treat checked-in release notes as source history, not live runtime proof.

+# Hulumath Context Boot
+
+## Purpose
+
+Hulumath is a public mathematics product built as a Django modular monolith.
+It combines mathematical identity, stories, competitions, courses,
+progression and constrained mathematical tools.
+
+## Repository Map
+
+```text
+backend/       Django applications, APIs, templates and static assets
+docs/          product, release and deployment documentation
+scripts/       deployment and maintenance helpers
+deploy/        production configuration templates
+context/       bounded repository identity for Universal Context
+```
+
+## Read Order
+
+```text
+AGENTS.md
+-> context/boot.md
+-> context/capsule.json
+-> README.md
+-> relevant document under docs/
+-> relevant Django application under backend/
+```
+
+Runtime credentials, databases, uploads and account data are never context
+inputs. Current production claims require a fresh JOps observation.
