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.

Offline-First
One of the two foundational forces shaping the whole system (the other is the threat-model). (See parking-system-architecture §1.)
A park may have no internet, intermittent connectivity, or be fully air-gapped. Nothing in the core operation may depend on a network being present.
What it forces
- Local auth — no external identity provider; hence local-jwt-auth and the rejection of logto-zitadel-oidc.
- Local database — sqlite on-site; remote PostgreSQL is a deferred, optional sync target, never a runtime dependency.
- Autonomous device decisions where possible — wiegand-into-controller lets the uhppote-controller decide even if the host is down; lpr-camera uses edge AI so recognition runs with no internet.
What it does NOT mean
Offline-first does not mean "no reconciliation." It means deferred, intermittent reconciliation — a manager's weekly USB stick, a daily phone hotspot, a monthly export. Only design for "never, by anyone" if that's genuinely true (see reconciliation for the network-free fallback controls).
