Next.js 16 App Router · Neon Postgres · Drizzle ORM · Auth.js v4 · Tailwind v4 · shadcn/ui · Zod · nanoid

Commands

• npm run dev · npm run build · npm run lint (lint script is bare eslint, not next lint)
• There is no test suite — no vitest/jest/playwright, no test script. Don't go looking for one and don't invent test commands. npm run build is the verification of record (it typechecks).
• One-off scripts: npx tsx scripts/<name>.ts with DATABASE_URL in the env (tsx is not a devDependency — it must go through npx). scripts/ holds three reusable utilities — seed.ts and the two Notion importers — and nothing there is part of the runtime.

Architecture

• src/proxy.ts is the middleware. Next 16 names it proxy, not middleware — searching for middleware.ts finds nothing. Matcher: /admin/*, /client/*, /quote/*.
• Admin auth is a double gate. proxy.ts redirects unauthenticated /admin traffic and stamps two headers (x-admin-pathname + x-admin-gate, a digest derived from NEXTAUTH_SECRET). src/app/admin/layout.tsx is a second, independent gate: it verifies that digest with safeEqual and fails closed by rendering (not redirecting — that would loop) when the proxy never ran. Shared helper: src/lib/admin-gate.ts, on Web Crypto so it works in both the edge and node runtimes. Reuse those helpers; don't bypass or reimplement either gate.
• Client access resolution. /client/<x>: per-IP rate limit (src/lib/rate-limit.ts, 20/min), then an HTTP fetch to localhost:$PORT against /api/internal/validate-slug, falling back to /api/internal/validate-token. Those internal routes are guarded by INTERNAL_SECRET. The localhost base URL is deliberate (hairpin NAT inside Docker), not a leftover.
• The query layers are split, and that split is what enforces LOCKED constraint #2. src/lib/client-view.ts exposes only client-safe projections — it deliberately omits quote_items, service prices, and payment amounts. src/lib/admin-queries.ts and the other *-queries.ts are admin-only. New client-facing queries go in client-view.ts; never import admin-queries from a /client/* route.
• Two distinct commercial artifacts, easy to confuse:
  • /quote/[token] → quotes table, single tier, 21-char nanoid token, served by src/lib/quote-service.ts
  • /preventivo/[slug] → proposals table, an A/B/C tier deck generated by the AI agent in src/lib/proposal/ (agent.ts calls the Anthropic SDK, output is Zod-validated by schema.ts, then assembleProposal in assemble.ts merges it with offer data). States: draft|published|accepted|rejected.
• Offer model: offer_macros → offer_micros (tiers A/B/C) → services, wired through join tables (offer_tier_services, offer_phase_services, …). importOfferIntoProject in src/app/admin/projects/project-actions.ts turns an offer into phases/tasks by grouping services on services.fase.
• Auth: a single admin credential from env (ADMIN_EMAIL/ADMIN_PASSWORD) — no users table — with a stateless JWT session (src/lib/auth.ts).

Architecture Constraints (LOCKED)

1. clients.token = campo separato rotatable, MAI primary key
2. quote_items MAI esposti via client API — solo accepted_total al cliente
3. deliverables.approved_at immutable once set
4. Auth: /client/[token]/* → middleware token check | /admin/* → Auth.js session
5. No file hosting v1 — documenti come URL esterni

Conventions

• Mutations are Server Actions, colocated as actions.ts (or *-actions.ts) inside the route folder. There is no REST API for admin: src/app/api/ holds only NextAuth, the two internal validation routes, and two client endpoints.
• Migrations are hand-written SQL in src/db/migrations/NNNN_name.sql, with gaps in the numbering (0002 doesn't exist — that's expected). drizzle.config.ts is present but drizzle-kit generate is broken: edit src/db/schema.ts and write the SQL by hand, keeping the two in sync. Applying a migration goes exclusively through the SSH/docker-exec procedure below — never through a throwaway script.
• Slugs and tokens are bearer credentials. Never commit their values (migration files included). They're generated with customAlphabet (CSPRNG) in src/app/admin/clients/new/actions.ts — never Math.random().
• Language: code and comments mix English and Italian; all user-facing UI and error messages are Italian.
• AI-generated HTML: never dangerouslySetInnerHTML on model output — use src/components/public/proposal/RichText.tsx, which whitelists bold/emphasis only.

Design System

Single source of truth: design-reference/DESIGN-SYSTEM.md ("Quiet Luxury" v1.0).

• Cardinal rule: semantic tokens only (bg-card, text-muted-foreground, border-border) — never raw Tailwind palette classes or hex literals. That's what makes dual light/dark work off the single .dark class toggle (FOUC guard in src/app/layout.tsx, tokens in src/app/globals.css).
• Fonts: Plus Jakarta Sans for UI, Geist Mono for numeric/tabular cells (prices, counts, dates).
• Per-page HTML mocks live in design-reference/pagina-*/ — replicate them faithfully.
• Reuse the existing primitives before building new ones: StatusBadge, SearchInput, SegmentedToggle, editable-cell, option-select/option-multi-select in src/components/ui/, and the shell in src/components/admin/AdminShell.tsx.
• .planning/UI-RULES.md and .planning/DESIGN-SYSTEM.md are SUPERSEDED — they mandate hex literals and forbid semantic tokens, the exact inverse of the current rule. Don't follow them.

GSD Workflow

Planning in .planning/. Use /gsd-plan-phase N → /gsd-execute-phase N. State in .planning/STATE.md.

Memory Discipline

Data Safety (LOCKED)

• Any migration, refactor, or deploy MUST NOT delete or truncate clients, projects, payments, or phases rows
• Before running any migration: verify it only adds columns/tables — never drops or truncates production data
• Confirm explicitly before any schema change that removes a column or table used by these entities

Deploy & DB Access (procedure)

• Environments: local → Gitea (remote is named gitea, NOT origin) → Coolify (prod, auto-deploys on push to main)
• Prod Postgres is NOT publicly exposed. Claude has working key-based SSH to root@178.104.27.55 and applies migrations directly via docker exec — no SSH tunnel needed from the user: cat src/db/migrations/NNNN.sql | ssh root@178.104.27.55 "docker exec -i xwkk0040w0kk0gsgcgog8owk psql -U clienthub -d clienthub -v ON_ERROR_STOP=1 --single-transaction" (container = xwkk0040w0kk0gsgcgog8owk, db/user = clienthub; if the container hash changes, find it by scanning docker ps for the one whose db has the payments table). A tunnel -L 54321:localhost:54321 is only needed to point local tooling at prod.
• Migrations are hand-written SQL in src/db/migrations/ (drizzle-kit generate is broken).
• Ordering: apply an additive migration to prod BEFORE pushing the schema-dependent code, so the live portal never queries a missing column.

Security

• Confirm before any destructive command (rm -rf, reset --hard, force push, DROP TABLE / drop-column, truncate, infra changes)
• Never print .env contents or credentials in plaintext output; using them internally to connect is fine
• Don't install packages without showing name + registry + version first
• Pushing to main is allowed automatically (standard local → Gitea → Coolify flow); never force-push to main
• Any change to this section: propose full new version, get approval before applying
