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
- escape() replaces &, <, >, ", and ' with HTML entities (&, <, >, ", ') and returns a Markup instance that avoids re-escaping when passed to escape() again.
- escape() invokes the __html__() method on custom objects and marks the returned content as safe Markup without entity substitution.
- Markup.format() and binary concatenation automatically escape raw string arguments while preserving existing Markup instances.
- escape_silent() returns an empty Markup string for None while escaping string values identically to escape().
- Markup.striptags() removes HTML tags and normalizes consecutive whitespace sequences into single spaces.
