+@abstract:
+North-star contractile for rsr-template-repo. This repository is the
+canonical template for Rhodium Standard Repository compliance. It provides
+the scaffold that all hyperpolymath repos should copy and customize.
+@end
+
+## Purpose
+
+The rsr-template-repo serves as the master template for all hyperpolymath
+repositories. It contains the complete set of contractile files, machine-readable
+specifications, and governance documentation that define the Rhodium Standard.
+
+Every new repository in the hyperpolymath estate should be initialized by
+copying this template and substituting the placeholder values with
+repo-specific content.
+
+## Anti-Purpose
+
+This repository is NOT:
+- A general-purpose project scaffold for external use (hyperpolymath-only)
+- A replacement for per-repo customization (all files must be bespoke)
+- A static template that never changes (evolves with RSR spec)
+- A runtime library or framework (build-time only)
+
+## If In Doubt
+
+If you are unsure whether a change is in scope, ask. Sensitive areas:
+- .machine_readable/ contractile definitions
+- RSR specification files
+- Governance templates
+- License policy documents
+
+## Committed Next-Actions
+
+### repo-initialization
