# Microgram: helix-helix-position

`station__algovigilance__microgram-helix-helix-position` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Compute position on the knowledge helix. Five turns: 0=Primitives (alphabet), 1=Conservation (grammar), 2=Crystalbook (laws), 3=Derivative Identity (calculus), 4=Mutualism (the point). Each turn has the same angular truth at higher resolution. Returns turn metadata, altitude, and what encoding layer you occupy.

## Agent metadata

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

## Input schema

- `turn` *number* (required) — Helix turn number (0-4). 0=Primitives, 1=Conservation, 2=Crystalbook, 3=Derivative Identity, 4=Mutualism.
- `theta` *number* — Angular position within the turn [0, 2π]. Default: 0 (entry point).
