# Terms and units

A concise reference for the words used throughout reality-grade banking.

Canonical: https://docs.bankeiz.com/glossary/
Reviewed: 2026-10-25; coordinated packages 129.0.0; ruleset 127.0.0.

## Architecture

**The system and its implementation**

| Term | Meaning |
| --- | --- |
| Proof-native economy | An economic system whose participating claims carry the required source, rights and proof. |
| Reality-grade banking | The interaction standard for holding, inspecting, receiving and deliberately moving that value. |
| Reality-grade infrastructure | The implemented Receiz primitives composed through SDK, MCP and AI Skills. |
| Bankeiz | An open implementation of reality-grade banking. |

## Identity, custody and proof

**Sources of authority**

| Term | Meaning |
| --- | --- |
| Receiz ID | Identity continuity admitted under the supported identity contract. |
| PBI | The implemented proof-bearing identity and supported account recovery boundary. |
| Original | The complete supported artifact/source with its carried proof and required history. |
| Custody | The actual authority and protected environment required to hold and operate a source. |
| Public proof | A deliberately disclosed original whose evidence scope is distinct from private access authority. |
| Vault | Separate custody with contained supported sources and a private original; public disclosure uses a different proof. |

## Value and units

**Keep the units with their source**

| Term | Meaning |
| --- | --- |
| Reserve | Admitted funded denomination and backing. |
| Settlement | Exact proof-native Phi with supported deterministic valuation. |
| Phi | The exact native value unit; use integer micro-unit strings where the contract specifies them. |
| Reserve Note | A Note whose funding is the admitted Reserve component. |
| Settlement Note | A Note whose funding is exact admitted Settlement Phi. |
| Settlement Reserve Note | A combined Note retaining both original components. |
| Valuation | A supported calculation or observation of value. |
| Liquidity | The actual available path and capacity for an exchange; a displayed valuation does not establish it. |

## Execution and recovery

**Operational states**

| Term | Meaning |
| --- | --- |
| Quote | The supported preparation/review result; a Market quote is advisory rather than a price lock. |
| Intent | The exact requested action, participants, source, units and recovery coordinate. |
| Nonce | A retained operation coordinate used to resolve the same original attempt. |
| Unknown | A submitted operation whose result has not been established; it is not an instruction to create another one. |
| Receipt | Evidence of the accepted operation and its bound result. |
| Idempotent recovery | Resolving the same intended operation without creating another financial effect. |
| Reconciliation | Admitting the original result under the existing contract; connection alone does not authorize it. |

## Implementation and conformance

A package release, protocol/schema generation, constitutional ruleset, application build and assessed host are separate coordinates. This manual documents the coordinated 129.0.0 packages; installed schemas retain their own v120/v122/v125/v126/v127 generations, and the ruleset is 127.0.0. A passing schema check establishes structure, not ownership or financial authority. Conformance names the actual requirements and assessed evidence scope; engineering fixtures do not qualify real custody or a deployed financial outcome.
