Sample

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.

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Case
HOW- Goal
- verify pkg:npm/bare-signals@5.0.0 signal handling and listeners
- Packages
- Environment
- node 22.23.2
- Created
- 2026-08-27T12:59:20Z
Contract
- package manifest exports Signal class and SignalEmitter in TypeScript definitions and requires Bare engine >=1.7.0
- Signal constructor accepts string signal names and resolves them to numerical signums via constants map
- Signal constructor throws SignalError with code UNKNOWN_SIGNAL when an unrecognised signal string is provided
- Signal instances provide start, stop, ref, unref, and close lifecycle methods delegating to the native binding
- calling start on a closed Signal instance throws SignalError with code SIGNAL_CLOSED
- Signal.Emitter attaches Signal listeners dynamically on newListener and tears them down on removeListener
- native C binding registers bare_signals__on_signal and bare_signals__on_close callbacks with uv_signal_t
