mAi fe33c8f577 feat(questions): single_choice + multi_choice modules (registry slots 5-6/7)
Two choice types share the editor (option list with add/remove rows) and
the results bar chart. The participant input differs (radio vs checkbox)
and the answer shape differs (string vs string[]) — those are per-module.

Files added:

- single_choice.ts + multi_choice.ts — schemas (each with options array
  ≥2 items), defaultStubs (Option A / Option B), per-type isAnswerEmpty,
  ingest with per-option counting + other_count for choices that don't
  match (handles renamed options between form versions)
- single_choice.input.svelte — radio-button rows
- multi_choice.input.svelte — checkbox rows + toggle helper
- choice.builder.svelte — shared option editor (add / remove with the
  ≥2 minimum invariant); both modules import this slot
- choice.results.svelte — shared bar chart per option + an
  "other / dropped" muted row when other_count > 0
- choice.test.ts — 11 cases covering schema (≥2 options invariant),
  isAnswerEmpty (per-type rules), ingest (option counting + other_count),
  CSV (single-string vs pipe-joined), adminCellSummary (per-type)

Both modules registered in QUESTION_MODULES (between long_text and
scale per the picker order).

101 server tests pass (was 91). svelte-check clean.

fdbck.msbls.de

Per-link feedback forms and live-chat masks. Anonymous, slug-gated, no auth required for participants.

Spun out from m/flexsiebels.de issue #63 — full design at docs/plans/feedback-feature.md.

Stack

SvelteKit 5 + Svelte 5 + bun + @sveltejs/adapter-node. Postgres + Supabase auth. Schema: fdbck.feedback_{instances,submissions,posts} on supa.flexsiebels.de (msupabase).

Run locally

cp .env.example .env  # fill SUPABASE_*
bun install
bun run dev

Test + check

bun run test    # rate-limit + public-scope unit tests
bun run check   # svelte-check (type errors / a11y)
bun run build   # adapter-node production build → ./build

Deploy

Dockerfile uses oven/bun:latest. Dokploy app: fdbck.msbls.de. DNS via Hostinger (handled out of band).

Structure

src/
  hooks.server.ts        — auth + public-scope policy gate
  lib/server/
    auth.ts              — cookie JWT + Supabase refresh
    fdb.ts               — Postgres `fdbck` schema accessor
    feedback.ts          — slug generator + DB helpers + rate-limit constants
    public-scope.ts      — anonymous-DB-access fail-closed gate
    rate-limit.ts        — in-memory token bucket
    schemas.ts           — Zod request validation
    supabase.ts          — admin + anon client singletons
  routes/
    +page.svelte         — landing
    f/[slug]/            — public participant page (form + live chat)
    admin/feedback/      — m's admin (list + detail + create)
    api/
      auth/              — sign-in / sign-out
      public/feedback/   — anonymous slug-gated endpoints
      admin/feedback/    — owner-scoped admin endpoints

Data model (canonical: design doc §5)

  • fdbck.feedback_instances — slug, title, description, owner_user_id, form_definition (jsonb), chat_enabled, status (open | closed), closed_at
  • fdbck.feedback_submissions — instance_id, display_name (nullable = anonymous), client_session_id, answers (jsonb), client_ip, user_agent
  • fdbck.feedback_posts — instance_id, display_name, client_session_id, body, hidden (m soft-moderate), client_ip, user_agent

Anti-abuse layers

  • 32-char base62 slugs (~190 bits entropy)
  • in-memory rate-limit (30 posts / 5 min, 10 submits / 5 min, per IP+slug)
  • honeypot field on forms + chat (silently dropped)
  • body length caps + closing kill-switch
  • noindex meta + robots.txt Disallow: /

Out of scope (v1)

Drag-drop form-builder · post reactions · realtime/SSE · CAPTCHA · trusted-tier owner sharing · branding/theming · auto-notifications. All have a clean upgrade path on the existing schema.
