Hello, World, Five Ways

No fixes were needed. Every implementation prints the exact line Hello, World!.

Summary Table

How verification actually went

Three of the five ran for real. Python, JavaScript, and Rust each executed on this machine and printed Hello, World! to stdout, confirmed both by the workflow's verifier and by an independent re-run.

Two were verified by inspection. Go had no toolchain installed, so that was expected. Java was the surprise: javac and java exist as command stubs on the system, but there is no actual Java runtime behind them, so an execution attempt returns "Unable to locate a Java Runtime." The verifier correctly recognized this and fell back to reading the source. The code is standard and would print correctly on any machine with a real JDK.

Observations

The implementations track the cultural norms of each language. JavaScript is the terse extreme: one line, no ceremony. Python and Java carry the most structure, each wrapping the print in a named entry point because that is what their communities expect to see. Rust and Go land in between, both requiring an explicit main but keeping the body to a single print call.

Line count is a rough proxy for required ceremony. JavaScript needs one line. The compiled and structured languages need three to six, mostly for the entry-point scaffolding that the runtime demands before any code runs.
