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. txtar.Archive struct holds Comment byte slice and Files slice
  2. txtar.Format serializes Archive with Comment and Files to formatted txtar bytes
  3. txtar.Parse parses formatted txtar bytes into Archive preserving Comment and Files
  4. txtar.Parse handles empty archive data returning empty Comment and empty Files
  5. txtar.Parse preserves multiple files and their file names and data contents in order
  6. txtar.Format followed by txtar.Parse roundtrips Archive data accurately
  7. txtar.Archive with empty comment formats files with standard header delimiters

Files

  • PROMPT.md
  • csx.json
  • go.mod
  • go.sum
  • main.go
  • spec.json
  • test/contract.go
