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.

  1. expand({ parsed: { HOST: 'localhost', PORT: '8080', ADDR: '${HOST}:${PORT}' } }).parsed.ADDR === 'localhost:8080'
  2. expand({ parsed: { DB_HOST: '${UNSET_DB_HOST:-127.0.0.1}' } }).parsed.DB_HOST === '127.0.0.1'
  3. expand({ parsed: { BASE_DIR: '/app', SUB_DIR: '${BASE_DIR}/data', FILE_PATH: '${SUB_DIR}/config.json' } }).parsed.FILE_PATH === '/app/data/config.json'
  4. expand({ parsed: { ESCAPED_DOLLAR: '\\$VAR_LITERAL' } }).parsed.ESCAPED_DOLLAR === '$VAR_LITERAL'
