Deterministic
Validates architecture-as-code graphs against deterministic lint rules and catches drift between your documented IR and actual codebase implementations. Ingests from OpenAPI specs or Backstage catalogs, merges IR fragments, runs structure and architecture validation (IR-STRUCT, IR-LINT codes), and reconstructs IR from live code in Node.js, Python, or C# to spot "dummy IR" scenarios where the design passes but the shipped code has direct database calls or undocumented routes. Runs offline in CI with reproducible exits, no LLM, no account. Reach for this when you need governance that fails the build on layering violations before merge, not post-mortem architecture review.

ArchRAD 0.7.2 running the zero-setup deterministic demo and scanning a repository into cited draft IR
Your architecture drifts before you write a single line of code. archrad validate catches it — deterministically, in CI, before the PR merges.
Define your system as a graph. ArchRAD compiles it, lints it against architecture rules, and tells you exactly what's wrong — with rule codes, not opinions.
New in 0.7.x —
archrad demoruns a full example with zero setup, andarchrad scandrafts an IR from any repo with every node cited tofile:line. Lint findings only decrease in this release; nothing that passed on 0.6.x can start failing. See the changelog.
Quick start (60 seconds)
npm install -g @archrad/deterministic
archrad demo
No IR file, no flags, no config — runs from any directory. Lints a bundled example and shows you the findings:
