Strict Product Mandate: ArchitectOS never modifies user code directly; it exclusively analyzes, explains, calculates impact, and generates actionable refactoring plans. Code modifications are executed by AI Agents or human developers.

🎯 Engine Precision & Accuracy Features

• 25 CWE-Mapped SAST Engine: High-precision rules covering SQLi, XSS, RCE, ReDoS, Prototype Pollution, NoSQLi, Open Redirect, Unsafe Deserialization, and Weak Cryptography.
• Context-Aware Noise Filter: Automatically suppresses false positives inside test blocks (describe/it), JSDoc comments, dead conditional branches, and when known sanitizers (DOMPurify, escapeHtml) are detected.
• Multi-File Taint Tracking Engine: Traces untrusted user inputs (HTTP req.body/searchParams) down to dangerous execution sinks across multi-file import graphs.
• Code Duplication Scanner: Token-fingerprinted Jaccard similarity engine detecting copy-pasted code blocks across monorepo packages.
• Framework Entrypoint Whitelist: Eliminates false positives for Next.js (GET, POST, generateMetadata, middleware), Remix, Vitest, and CLI entrypoints.
• Tarjan SCC Cycle Detection: Mathematically sound circular dependency cycle detection for complex monorepos.
• Public Scoring Transparency: Fully documented formulas and deduction rules in SCORING.md.

🧪 Real-World Benchmark Verification (v1.2.1 Engine Breakdown)

ArchitectOS is battle-tested and dogfooded across major open-source codebases with transparent sub-metric scoring:

Repository	Files	Overall	Arch	Sec	Qual	AI	UI	Scan Speed	Top Focus Area
excalidraw/excalidraw	520+	88/100	92	84	90	94	80	<18ms	Canvas Component Decomposition
calcom/cal.com	1,400+	84/100	80	88	82	90	80	<45ms	Booking Service Layer Isolation
shadcn/ui	120+	96/100	98	95	96	95	96	<8ms	UI Component Primitive Boundaries
cgseyhan/architectos	51	100/100	100	100	100	100	N/A	<19ms	Native Self-Hosted AST Governance

Note: Pure CLI / backend repositories (e.g. architectos) omit UI Architecture scoring.
