# Signal

Raw information emission

Layer: Infrastructure · Category: Data Structures

## Mechanism

Emission of information into environment. No guaranteed recipient. Fire-and-forget.

## Invariants

- Broadcast: Signal is available to any observer in the medium.
- Distinguishability: the emission is separable from the medium background by an observer. Relevance is the receiver's judgment, not the emitter's.

## Failure modes
