Policy Enforcement: Every operational metric must originate only from verified RTWO backend services. Until real infrastructure is connected, all modules display truthful development states. The RTWO_REQUIRE_REAL_DATA=true environment flag gates all service methods behind truthful null/empty returns. The RTWO_TRUTHFUL_STATUS_MODE=true flag enforces truthful status display across all dashboards.

RTWO-SHRD-001Architecture Fix — Post Phase 20v1.0.0-sharedStructure CompleteActive — No External Dependencies

RTWO Shared Module

Purpose

The Shared Module provides cross-cutting type definitions, canonical module ID constants, and shared base interfaces consumed by all 22 RTWO modules. It eliminates redundant type aliases, ensures consistent module identification, and defines the shared contracts that enable the Integration Framework to manage all modules uniformly.

Responsibilities

▸Define RTWOTimestamp as the single canonical timestamp type
▸Define RTWOModuleVersionDescriptor as the standard version descriptor shape
▸Maintain RTWO_MODULE_IDS as the canonical module ID registry
▸Define IBaseEngine as the shared base contract for all engine singletons
▸Define IReadinessProvider as the shared readiness contract
▸Define IEventPublisher as the shared event publishing contract
▸Define IStorageAdapter as the shared storage backend contract
▸Define IConfigurationConsumer as the shared configuration contract
▸Define IPluginHost as the shared plugin hosting contract
▸Define ICryptographyDelegate for Wallet → Cryptography delegation
▸Define INativeCurrencyProvider for Asset → Native Currency integration

Architecture

Pattern

Shared Type Library — No Runtime Dependencies

Layers

types.ts — Primitive types and module ID constants

engine-interfaces.ts — Shared base contracts

index.ts — Unified re-export

The Shared Module is a pure TypeScript type library with no runtime dependencies. It contains only type definitions, interfaces, and constants. All 22 RTWO modules import from this module to ensure type consistency and contract alignment.

Domain Models

RTWOTimestamp

Universal timestamp type: number | null — replaces 18 redundant aliases

RTWOModuleVersionDescriptor

Standard module version descriptor shape

RTWOReadinessReport

Standard readiness report with blockers and production status

RTWORuntimeConfigurationUpdate

Runtime configuration update payload

RTWOPlugin

Plugin descriptor with type, version, and author

SigningRequest / SigningResult

Cryptography delegation request and result types

NativeCurrencyState

Native currency state for INativeCurrencyProvider

Services

N/A

Shared Module contains only type definitions and interfaces — no service implementations

Interfaces

IBaseEngine

Base contract for all RTWO engine singletons

IReadinessProvider

Readiness contract consumed by System Registry and Integration Framework

IEventPublisher

Event publishing contract for all publishing modules

IStorageAdapter

Pluggable storage backend contract

IConfigurationConsumer

Runtime configuration update contract

IPluginHost

Plugin hosting contract for extensible engines

ICryptographyDelegate

Signing delegation contract for Wallet Engine

INativeCurrencyProvider

Native currency state contract for Asset Engine

Dependencies

None — zero runtime dependencies

Integration

↔Imported by all 22 RTWO modules
↔RTWO_MODULE_IDS consumed by System Registry for canonical ID validation
↔IBaseEngine consumed by Integration Framework Service Registry
↔IReadinessProvider consumed by System Registry Readiness Tracking Service
↔IEventPublisher consumed by Event Bus Publisher Registry
↔IStorageAdapter consumed by Ledger Engine
↔IConfigurationConsumer consumed by Integration Framework Configuration Loader
↔IPluginHost consumed by Consensus Engine, Smart Contract Runtime, and Virtual Machine

⚑ Truthful Data Policy

✓Type definitions only — no runtime data
✓ICryptographyDelegate.isCryptographyAvailable() always returns false until connected
✓INativeCurrencyProvider returns null values until Native Currency Engine is connected
✓IReadinessProvider.isProductionReady() always returns false until real backend connected

✓ Acceptance Criteria

□RTWOTimestamp defined and adopted by all modules

□RTWO_MODULE_IDS constants defined for all 22 modules

□IBaseEngine interface defined and implemented by all engine singletons

□IReadinessProvider interface defined

□IEventPublisher interface defined

□IStorageAdapter interface defined

□IConfigurationConsumer interface defined

□IPluginHost interface defined

□ICryptographyDelegate interface defined

□INativeCurrencyProvider interface defined

Shared Interface Catalog

Cross-module contracts defined in RTWO-SHRD-001

IBaseEngine

Shared base contract: moduleId, moduleName, version, phase, status, getDescriptor(), getReadinessReport()

Consumers: All 22 engine modules

IReadinessProvider

isProductionReady() → false, getBlockers(), getReadinessReport()

Consumers: System Registry, Integration Framework

IEventPublisher

getPublisherId(), publish(eventType, payload) → false, getSupportedEventTypes()

Consumers: Event Bus, all publishing modules

IStorageAdapter

get(key), set(key, value), delete(key), isConnected(), getStatus()

Consumers: Ledger Engine, Integration Framework

IConfigurationConsumer

onConfigurationUpdate(config), getConfigurationScope()

Consumers: Integration Framework → all modules

IPluginHost

acceptPlugin(plugin), activatePlugin(id), getSupportedPluginTypes()

Consumers: Consensus Engine, Smart Contract Runtime, VM

ICryptographyDelegate

requestSigning(request) → SigningResult, isCryptographyAvailable() → false

Consumers: Wallet Engine ← Cryptography Engine

INativeCurrencyProvider

getNativeCurrencyState() → NativeCurrencyState (null values until connected)

Consumers: Asset Engine ← Native Currency Engine

Architecture Status: RTWO Architecture v1.0 is frozen. All 23 modules are structurally complete with full domain models, service interfaces, and integration contracts defined. Production readiness requires real infrastructure connection for each module. The Truthful Data Policy ensures no module claims production readiness until its real backend is connected and verified.
