+  CUSTODIAN SUGGESTION — generated by `custodian register-project`
+
+  This file was written by the Custodian State Hub registration workflow.
+  It contains the standard State Hub integration block for this repository.
+
+  A Claude Code agent in this repo should:
+    1. Read this file and the existing CLAUDE.md side by side
+    2. Integrate the sections below into CLAUDE.md — preserve all existing
+       project-specific conventions; add or update the hub integration block
+    3. Delete this file once integration is complete and commit the result
+
+  Do NOT add this file to .gitignore. It is a temporary artefact that signals
+  pending integration work to the repo agent.

+
+# DEPRECATED — see project_rules/
+
+This file was the monolithic CLAUDE.md template. It has been replaced by the
+modular @-import structure in `scripts/project_rules/`.
+
+`register_project.sh` now generates:
+  - `CLAUDE.md`                        — thin @-import index (9 lines)
+  - `.claude/rules/repo-identity.md`   — purpose, domain, slug, topic ID
+  - `.claude/rules/session-protocol.md`— orient → inbox → workplans → brief
+  - `.claude/rules/first-session.md`   — bootstrap flow (delete once past FSP)
+  - `.claude/rules/workplan-convention.md` — prefix, location, delegates to global
+  - `.claude/rules/stack-and-commands.md`  — language, deps, dev commands (stub)
+  - `.claude/rules/architecture.md`    — design overview (stub)
+  - `.claude/rules/repo-boundary.md`   — what this repo does NOT own (stub)
