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.

LPR Camera
License-plate-recognition camera (recommended: Milesight edge-AI LPR). For casual/transient vehicles, the plate acts as ticket + an independent record. (See parking-system-architecture §8, §9.)
- Edge AI: recognition runs on-device, so it keeps working with no internet — fits offline-first.
- It's a host-side identity source: only the host sees the read; the host decides and commands the relay open (the uhppote-controller is demoted to a commanded relay for that lane). See entry-exit-readers.
- Being host-in-the-loop is good for fraud detection — you get two independent records (the host's signed append-only-event-chain entry + the controller's remote-open event) that should reconcile one-to-one; any mismatch is an anomaly.
- Mounting: within ~15° of vehicle travel at a controlled chokepoint for best reads.
