memory-md-inventory-vs-directive-architecture-rule

MEMORY.md must contain only behavioral directives and pointers — never inventory. Mixing ‘you must behave this way’ content with ‘this is what exists’ content (Docker versions, container counts, CLI paths) violates the index contract. Inventory belongs in topic files; MEMORY.md is the routing brain, not the fact store. This distinction prevents silent bloat accumulation over time.
