  "summary": "Iter-4 backend + frontend regression PASS. Backend pytest: 47/47 PASS — added 5 new test classes covering plan economics (reach 200–1.5k/1.5k–3k/3k–10k/10k+ + adjustments=1 for ALL plans + 'Extra change: €5' feature), 20-track music catalog, extra-adjustment Stripe checkout (missing campaign_id→400, invalid→404, valid→200 with cs_ session id, payment_transactions row persisted with item_type+campaign_id, /payments/status returns item_type), invalid item_type rejection (random + content_pack both 400), and AI auto-language by profile.country (Portugal→language='pt', Italy→language='it'). Frontend Playwright: Login + Signup translate to PT when language is switched on Landing/Header (texts 'Bem-vindo de volta', 'Entrar', 'Aceder ao painel', 'Criar conta', 'Anúncio ao vivo em 10 min' all present); LanguageSwitcher correctly shows 'PT' (iter-3 'PO' bug fixed). Onboarding step-3 Content: input accept='image/*,video/*' (both supported), Continue disabled with 0 uploads → enabled after 1 upload (4-fixed-slot rule replaced by min-1 rule). Onboarding step-4 Plan shows reach '200–1.5k', '1.5k–3k', '3k–10k', '10k+' for the four plans, each card shows 1 adjustment/mo. Onboarding step-5 Review: AI auto-prefilled BOTH headline + description in Portuguese ('Oficina Mecânica de Confiança em Lisboa' + full PT description) on entering the step; clicking ai-generate-copy-btn re-fetched and updated the description. /api/music/catalog returns 20 tracks (verified via in-page fetch).",

    "server.py:822-850 generate_copy reads profile.country (default 'Portugal') and instructs the LLM to auto-detect language; falls back to niche.headlines[0] in English on AI error. Acceptable but the fallback won't match the user's country language — minor.",

Run with REACT_APP_BACKEND_URL exported. Stripe extra_adjustment tests stop at session creation (we do NOT pay through Stripe in tests) — the idempotent 'paid' grant path on /payments/status was code-reviewed but not exercised live. To exercise it, insert a fake payment_transactions doc + monkey-patch stripe_sdk.checkout.Session.retrieve. The CampaignDetail 'Buy extra change (€5)' button + Music modal (20 tracks) flow on /dashboard/campaigns/{id} were not driven via Playwright in this iter-4 run — they're code-verified and the underlying API endpoints are pytest-covered. LanguageSwitcher on /onboarding is MISSING (only on Landing Header + DashboardLayout sidebar). i18n key 'pt' renders 'PT' correctly (iter-3 'PO' bug fixed at /app/frontend/src/components/LanguageSwitcher.jsx).",
