org.camunda.bpm.* — with the same public classes, interfaces, and method signatures. The Maven coordinates are rebranded (org.aseeflow.bpm), so you update your dependencies, but the API you program against stays the same: existing code and imports remain source-compatible. (ASEE Flow 1.0 is based on Camunda Platform 7.24.)
Because the Java API is the same, Camunda’s published Javadoc documents the classes ASEE Flow ships, so it is an accurate reference for ASEE Flow:

The Javadoc stays on docs.camunda.org precisely because the
org.camunda.bpm.* packages are unchanged, so Camunda’s reference matches ASEE Flow’s classes one-to-one.
