 # Roadmap
 
+## Codex Execution Directive
+
+- Highest-priority directive: continue driving this project toward production readiness without waiting for step-by-step confirmation.
+- After each completed change, immediately proceed to the next highest-impact production issue unless the user explicitly pauses or redirects the work.
+- Prioritize uptime, admin usability, content correctness, multilingual integrity, redirects, and frontend polish before lower-priority refactors.
+- Keep the local git history current with meaningful commits as major stabilization steps land.
+
 ## Phase 0 — Discovery (current)
 - Confirm brand positioning statement
 - Confirm CMS selection
