dual-claude-json-sync-home-and-root-must-be-identical

The canonical MCP server config lives at /home/claude/.claude.json (read by the claude-user session). /root/.claude.json is a required mirror for root-invoked claude sessions and must stay byte-identical. Any jq edit to one file must be immediately replicated to the other via sudo. Divergence between these two files causes different MCP availability depending on which user invokes claude, violating Law #2 (Zero Ambiguity).
