Use a package diagrams

Use a package

Start with how the application begins, then follow data between its folders. Open an operation to see its decisions, calls, failures and cleanup. Its explanation supplies the exact contract and linked dependencies.

This view includes 1 application source files. Package and interface boundaries show checked contracts; their runtime implementations are not expanded. The views describe the checked program, not desired requirements or a recorded execution.

Where execution begins

Startup

It prints add with left 20 and right 22. source

Data flow

No calls cross the source files in this view. Follow local operations in the file sequences below.

Follow the data

Each row opens the complete operations and call sites behind one pair of logical units. A grouped arrow records calls between those units; connected arrows need not belong to the same execution path.

These are static call boundaries, not a request trace. Interface implementations and foreign internals stop at their checked contracts. Dotted arrows defer a callback or browser action. Imports alone do not imply a call.
