Cross-build locked stack decisions and decision criteria for divergent choices. Read at the start of any new project. Covers runtime, language, ORM, auth provider, component library, deployment, and observability — what's a hard pick, what depends on context, and the criteria for context-driven picks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Factory stack ## Locked decisions (no per-project relitigation) | Layer | Choice | Why | |---|---|---| | Runtime | Next.js App Router | Convergent across all customer repos; ecosystem fit for tRPC / server actions / Vercel deploy | | Language | TypeScript | Convergent; non-negotiable | | Validation | Zod | Pairs with both tRPC and server actions; field registry pattern depends on it | | Server state | TanStack Query | Convergent across all repos that need server state | | DB | Postgres via Neon (dev branches) or RDS (compliance) | Convergent | | Forms | react-hook-form + Zod via resolver | Convergent | | Email | Resend | Convergent | | Linting | ESLint + Prettier + ESLint Drizzle rules where applicable | Convergent | | Env vars | t3-oss/env-nextjs (Zod-validated, server/client split) | Convergent | ## Decision-criteria choices (pick per project; document in project's CLAUDE.md or DECISIONS.md) ### ORM — Drizzle vs Supabase auto-types vs raw pg - **Drizzle** — default. Schema partitioning by domain (`_shared.ts`, `<domain>.ts`) + shared `timestamps` helper. `pgTableCreator()` for prefixing if the DB is shared. …

How to install
mdr add nonlinear-xyz/factory-kit/factory-stack@sha256:a10330467276e23dThe line at the top of this page pins the label git:20260716.517fb94, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
