+== Live-Files: RSR 2026 Control Plane
+
+You are an agent operating on the Hyperpolymath Epistemic Fleet. This
+repo contains the orchestration logic for all satellite and core repos.
+
+=== Structural Rules
+
+* *Tiers*: Repos are organised into Core, Governance, Infrastructure,
+SSG, MCP, and Research.
+* *Filing*: Use `just file` to move root-level repos into their correct
+tiers.
+* *Restoration*: Use `must restore` to fix symlinks and directory
+structures.
+* *Visibility*: Use `just v` to see a two-ply colour-coded map.
+
+=== Standards
+
+* No Makefiles. Use Just/Nickel.
+* Oxford British English only.
+* Prioritise nerdctl for all container tasks.
