Kingdom • Conformance packs + deterministic validators

# Receipts. Not promises.

Vendor‑neutral governance substrate: Policy Packs, deterministic PASS/FAIL/HOLD, and replay‑verifiable receipts packaged as portable Conformance Packs.

### Conformance becomes replay

Audits become replay exercises over Conformance Packs — not interviews and screenshots. Missing/stale evidence → HOLD (fail‑closed).

Adoption L0–L3

### Start small, scale assurance

- L0: record signed receipts
- L1: independent replay verification
- L2: enforce gates at compute admission + transfer/egress
- L3: high assurance + privacy‑preserving verification + sampling audits

DOI Public draft

### 10.5281/zenodo.18236114

Procurement language + acceptance tests are included in the RFC so buyers can paste requirements directly.

## Core concepts (buildable)

A minimal set of contracts that preserve determinism and fail‑closed behavior across vendors.

Policy Packs

### Machine‑readable admissibility rules

Versioned, signed rulesets that replace governance PDFs with deterministic evaluation.

Validators PASS/FAIL/HOLD

### Deterministic decision semantics

Stable reason codes; ambiguity returns HOLD (fail‑closed for sensitive side effects).

Receipts Replayable

### Portable verification artifacts

Signed records that auditors can independently replay under pinned versions and freshness bounds.

### Procurement‑ready by design

Kingdom is written for builders, operators, and buyers. It includes paste‑ready procurement language, acceptance tests, and an adoption plan that avoids badge inflation.
