# Microgram: primitive-succession

`station__algovigilance__microgram-primitive-succession` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Law of Primitive Succession: identify dominant primitive of a system and predict its successor. S_next = S + P_new where P_new is the highest-value missing primitive. Validated across 19 transitions (computing, science, math, PV).

## Input schema

- `dominant` *string* (required) — Dominant primitive of the system: boundary, state, void, causality, frequency, quantity, comparison, sequence, location, existence
- `has_boundary` *boolean* — System has boundary primitive (∂) — typed interfaces, membranes, separation
- `has_state` *boolean* — System has state primitive (ς) — observable, cumulative, persistent
- `has_void` *boolean* — System has void primitive (∅) — absence-awareness, nothing as structure
- `has_causality` *boolean* — System has causality primitive (→) — traceable cause-effect chains
- `has_frequency` *boolean* — System has frequency primitive (ν) — periodic, rhythmic, scheduled
- `has_quantity` *boolean* — System has quantity primitive (N) — measured amounts, conservation
- `has_comparison` *boolean* — System has comparison primitive (κ) — symmetric difference, negotiation
- `has_sequence` *boolean* — System has sequence primitive (σ) — ordered steps, dependency chains
