# Microgram: transbeyesian-propagator

`station__algovigilance__microgram-transbeyesian-propagator` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Transbeyesian belief propagator: computes cross-domain signal updates using shared primitive structure (transfer_weight) as the propagation channel. posterior_B = prior_B * (1 + weight * evidence_A / threshold). Higher transfer weight + weaker prior = stronger update.

## Agent metadata

- `idempotent`: true
- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
