Platform governance is rarely broken by large decisions.

It erodes through small exceptions.

A special configuration is introduced for a specific cluster.
A different network policy is applied to solve an urgent issue.
A deployment process is modified “just for this case”.

Each change is justified locally.

Over time, the platform begins to diverge from its original architecture.

Implication:

When exceptions accumulate without structural reconciliation, governance slowly drifts away from design.

The platform still functions, but its behavior becomes increasingly difficult to reason about.
