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. SnapshotState.create initializes state with NodeSnapshotEnvironment and matches new snapshots when updateSnapshot is 'all'.
  2. SnapshotState.prototype.save writes snapshot files to disk with formatted serialized contents.
  3. When updateSnapshot is 'none', SnapshotState.prototype.match passes for matching values and fails with actual/expected diffs on mismatch.
  4. SnapshotState.prototype.pack returns matched and unmatched counters for executed snapshot assertions.
