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. parseCLI requires 'vitest' as the leading argument token and transforms positional arguments into filter paths while mapping flags to normalized options
  2. assert parseCLI rejects leading binary tokens other than 'vitest' with a descriptive Error
  3. assert 'run' mode populates options.run, extracts positional test file paths into filter array, maps --no-isolate to isolate: false, and casts --bail to number
  4. assert 'watch' mode populates options.watch and nests dot-notation flags like --browser.name into options.browser object
  5. assert repeated flags like --reporter accumulate into array, --coverage expands to { enabled: true }, and --testTimeout parses as numeric value
  6. assert 'related' mode stores file targets in options.related, defaults passWithNoTests to true, and resets filter array to empty
  7. assert passthrough arguments after double dash are preserved in options['--']
