This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- antlr.NewParseTreeWalker traverses parse trees in depth-first order triggering EnterEveryRule, VisitTerminal, and ExitEveryRule events on custom listeners embedding antlr.BaseParseTreeListener.
- antlr.TreesStringTree converts parse tree rule contexts and terminal nodes into a LISP-style S-expression string representation using the provided rule names.
- antlr.NewBailErrorStrategy cancels parse execution upon encountering syntax errors by setting a ParseCancellationException on the parser and recording the error on active rule contexts.
