# Silent Substrate Test v0.1

**Status:** Interpretive pressure-form test of quiet propagation. Not proof of propagation. Not mind-reading.

## Core question

Can a framework propagate through silent contact before visible engagement appears?

## Pressure form

```text
Sₜ = AₜBₜ − Pₜ
```

When a dense HIR/OAM artifact has high alignment and structural coherence but also high novelty/friction pressure, ordinary replies may remain low even if the artifact has contacted viable substrate.

## Distinctions

- **Ignored:** flat or decaying downstream field; no recurrence, no later echoes, no structural carryover.
- **Mulling:** delayed public recurrence, later comments showing recognition, link clicks, or cross-thread echoes.
- **Silent carrier formation:** later independent recurrence of distinctive structure or marker phrases without immediate standard engagement.

## Boundary

- no mind-reading
- no individual profiling
- no social scoring
- public aggregate signals only

The mycelium does not spread through noise.  
It spreads through viable substrate.
