# Formula Registry

Every verdict's `verdict_id` is the SHA-256 of its canonical receipt payload. The `formula_version` tells you how that verdict was produced and how it verifies.

## Versions
- **`deterministic-synth-v1`** — deterministic synthesis from the evidence ledger. The receipt is byte-reproducible: re-running the formula on the same payload yields the same `verdict_id`.
- **`live-llm-v1`** — an LLM produced the probability (stochastic). The receipt anchors the *content* (hash-only verification), not a deterministic byte-replay.
- **`perspective-v1` / `perspective-v1.5`** — multi-perspective claim decomposition with per-claim evidence ledgers.
