Vaults never read each other directly — what crosses the boundary is validated on the way out and in.
The federation mechanism: when individual and team systems work together, they never read each other directly. What crosses the boundary passes through a publishing layer that validates on the way out and on the way in — the same plausibility and quality rules, now applied at the interface. Bad or implausible data doesn't propagate between systems; it's flagged at the boundary. The publishing tier and the validation loop combined into one thing: data contracts between systems with quality gates. The moat isn't isolation — it's a shared standard with sovereign nodes joined by validated, one-way exchange.
