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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. caddy.NewReplacer initializes a replacer supporting custom variable assignments with Set and Get
  2. caddy.Replacer.ReplaceAll substitutes custom and environment variable placeholders in input strings
  3. caddy.Replacer.Map dynamically resolves custom placeholders using provider functions
  4. caddy.Replacer.ReplaceOrErr validates template placeholders and fails on unrecognized variables
  5. caddy.Replacer.Delete unsets previously registered custom variables
