 * Repository-aware graph limits. The file budget tracks the repository size

 * the node/edge budgets always keep the full configured ceiling. Large repos
 * therefore reach honest `partial` coverage at the real cap instead of an
 * artificially lowered one (Scale V4 / D2b: no node-budget down-scaling).
