Turborepo (pnpm workspaces) with all dependencies pinned to latest mutually-compatible versions: turbo 2.9, TypeScript 6, Fastify 5, React 19, Vite 8, better-sqlite3 12 + Drizzle ORM 0.45. Layout: - apps/server Fastify backend (local JWT auth + role guard, /health) - apps/web React 19 + Vite 8 operator SPA - packages/db Drizzle schema on SQLite/WAL; append-only events + users - packages/devices reader/printer/relay adapter interfaces (intent-only relay) - packages/shared shared domain types Architecture constraints from the design wiki are encoded in the scaffold: append-only hash-chained + signed event log, device-agnostic adapters, "a barrier is not a door" (relay expresses intent only), fully-local offline-first auth. wiki/ is an LLM-maintained Obsidian knowledge base (28 pages) ingested from the architecture & design notes, with its own maintenance schema. Verified: pnpm install, full turbo build (5/5), server boots and serves /health, drizzle-kit generates the initial migration.

Safety Principle: A Barrier Is Not a Door
A vehicle barrier must not be driven as a timed "door open for N ms" by the application — a timed auto-close can drop a boom on a vehicle or person. (See parking-system-architecture §5.)
- Physical safety lives in the barrier operator's own firmware — induction loops, anti-crush, auto-reverse. (Recommended barrier operators in the bom are chosen because they own this.)
- The application and any relay board only ever express intent ("open"); they never time or
force a close against a vehicle. Reflected in the device-adapter-pattern's
pulseOpen. - Holds regardless of which relay device is used — uhppote-controller or esp32-custom-controller. The ESP32 design restates it: "the ESP32 only signals intent" (see fail-state-safety).
