The section documented a 5-method port interface and claimed "no other system
ever asks what is on tile X". The real surface is 15 methods and peekItem does
ask exactly that, so the doc was misleading about a subsystem it exists to
explain. It also showed a tryPutItem signature that no longer matches.
Describes what is there now, grouped by purpose, and separates the two claims
that had been conflated: item transport is still port-only, but tile topology
is genuinely coupled to BuildingSystem because belts are Buildings for cost and
construction. The v2 migration note is qualified accordingly.
