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.

Case
HOW- Goal
- Demonstrate how caddyhttp request variables replacer resolves context variables and treats unset http.vars placeholders as known.
- Symbols

- caddyhttp.RequestVarsReplacer
- Environment

Contract
- The caddyhttp replacer recognizes all {http.vars.*} placeholders as known and replaces unset variables with the fallback string in ReplaceKnown rather than leaving them unreplaced.
- Context variables set via caddyhttp.SetVar are dynamically resolved by {http.vars.<name>} placeholders in the replacer.
- Setting a variable to nil via caddyhttp.SetVar deletes it from the request context variable map.
- The replacer resolves standard HTTP request properties such as method, path, query parameters, and headers alongside custom context variables.
- VarsMatcher evaluates placeholders in rule values against stored context variables without expanding placeholder syntax inside the stored values.
