@stronghold-dr/core

Core engine for Stronghold -- open-source disaster recovery intelligence for AWS.

This package contains the pure business logic: infrastructure discovery, dependency graph analysis, DR validation, service detection, evidence model, scenario coverage analysis, DRP generation, posture history, and governance.

@stronghold-dr/core has zero framework dependencies. It can be used from the CLI, a server, tests, or custom integrations.

It is designed for TypeScript projects that want Stronghold's recovery analysis engine without taking a dependency on the CLI package.

Installation

npm install @stronghold-dr/core

What's inside

• AWS Discovery -- Read-only scanners for 16 AWS services, normalized into a dependency graph
• Service Model -- Automatic service detection from CloudFormation, tags, topology, and manual definitions
• DR Validation -- 39 rules across 6 categories (backup, redundancy, failover, detection, recovery, replication)
• Evidence Model -- Five maturity levels (observed, inferred, declared, tested, expired) with confidence-weighted scoring
• Scenario Coverage -- AZ failure, region failure, SPOF failure, data corruption analysis with coverage verdicts
• DRP Generation -- Declarative recovery plans and executable runbooks in YAML
• Posture Memory -- Scan history, finding lifecycle, DR debt tracking, and trend analysis
• Governance -- Ownership tracking, risk acceptance, and custom policy enforcement
• Graph Analysis -- SPOF detection, blast radius, criticality scoring, circular dependency detection

Usage

import { awsScanner, runValidation, detectServices, analyzeBuiltInScenarios, generateDRPlan } from '@stronghold-dr/core';
