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
- ensureDir creates nested directory structures if they do not exist
- outputJson and readJson write and read JSON documents while automatically creating parent directories
- outputFile writes string data creating parent directories automatically and readFile retrieves the written content
- copy recursively copies directory hierarchies and supports custom filter functions
- emptyDir deletes all contents within a directory while leaving the directory itself intact
- pathExists accurately checks the existence of files and directories
- remove recursively removes directories and files without throwing if the target does not exist
- move moves files and directories across paths with optional overwrite
Files
- PROMPT.md
- csx.json
- package-lock.json
