Interoperability improvement direction needs careful on-site detail in Yantai

Structural shifts to notice

Interoperability appears as a count change but is structural adjustment across scenarios and districts. Safety as a precondition is the thread marking where opportunity and pressure sit for planners who must decide soon.

Why regions diverge

Base conditions, habits and pace rewrite results from one area to the next. Experience as a long-term metric is the difference that copied experience cannot transfer when local reality differs from the original one.

Details aligned in Haiyang

In Haiyang we confirm base-condition match, clear responsibility and clear exception ownership for each node. These points once caused misunderstanding; aligning early prevents rework on site before it begins.

Interoperability's real test is the angry traveller with a dead battery. In Haiyang we make sure help exists and is named before we claim openness, because a network that cannot support its own users is just a map with a lot of empty pins. A pin on a map means nothing if the person beside it cannot get help, and we refuse to call that openness.
