Protocol Maker

AI longevity engine. Blood work in → personalized protocol out. Tracking + retest loop closes the feedback cycle.

Positioning

• Target user: Romanian health-conscious adults 28–45 with disposable income. People who already test their blood once a year and follow Peter Attia / Bryan Johnson / Rhonda Patrick. Not medical patients — lifestyle optimizers.
• Primary market: Romania (RON pricing, eMAG sourcing, Synevo / Regina Maria / MedLife PDF parsing). US / EU expansion is G4/G5 in the plan, not day-one.
• Framing: "longevity protocol coach" (like Whoop or Noom's domain), NOT "health dashboard" (like MyChart). Every AI output is lifestyle optimization, not diagnosis. Legal copy on /privacy + /terms is explicit.
• Language: English UI across the app, Romanian-facing marketing copy on landing once the founder locks H2. Labels in a future i18n dict so RO translation is 1 PR away.
• Business model (not yet shipped): free tier = lifestyle-only protocol + 1 AI generation / month. Paid €9.99/mo = unlimited regen + Claude Sonnet + daily chat. Covers Anthropic at ~100:1 conversion ratio. See AUDIT_AND_PLAN.md § G1.
• Moat: three things competitors don't combine — (a) deterministic engine + AI coach (reproducible, not chatbot-random), (b) device-aware tracking (130+ wearable models → capability-filtered SmartLog), (c) overnight auto-regen so the protocol drifts with your data, not your memory.

What it does

1. Onboarding (5 steps, ~5 min) — collects 150+ optional fields stored in profiles.onboarding_data JSONB. Required: age, height, weight.
2. Protocol generation — Claude Sonnet 4.5 (primary) → Groq Llama 3.3 (fallback) → deterministic engine (always works). Includes biomarker classification (38 markers), pattern detection, PhenoAge bio age, DunedinPACE-style velocity, lifestyle-aware longevity score, organ-system breakdown, Bryan Johnson comparison, full nutrition (3 options × 4 meal types + daily maximums), supplement stack with how-to + universal rules, daily schedule with school/work blocks, exercise plan personalized to gym access, sleep with full bedroom checklist + hygiene rules, pain points + flex strategies, doctor discussion in 4 categories, 12-week roadmap, shopping list with eMAG links.
3. Daily tracking — Smart Log time-aware bottom sheet (morning/midday/evening/night), 25+ metrics including all wearable-grade fields (sleep stages, HRV during sleep, blood O₂, BP morning/evening, antioxidant + AGEs indices). 14 daily habits across categories.
4. Statistics — every metric trended; "your X improved by Y% from when you started the protocol".
5. Retest loop — Settings → Upload new blood test → auto-regen v2 with diff vs v1 on history page.
6. Auto-regen cron — every 3 AM Romania time, rolls 7-day daily metrics averages back into the profile and regenerates the protocol so it stays current.
7. Chat — Claude-streaming, full-context coach (loads profile + protocol + biomarkers + last 14d metrics + last 7d compliance).

Stack

• Next.js 16.2.4 (App Router, Turbopack)
• React 19, TypeScript strict
• Tailwind v4 (CSS-based config via @theme inline, @plugin "@tailwindcss/typography")
• Supabase (Auth + Postgres + RLS + JSONB heavy)
• Anthropic Claude Sonnet 4.5 + Groq Llama 3.3 + deterministic fallback
• Recharts for charts, react-markdown for chat rendering, SWR for client data fetching
• Upstash Redis for rate limiting (3 protocols/day, 30 chat/hour) — bypassable via RATE_LIMIT_DISABLED

Repo conventions

• Single source of truth — counts (biomarkers, patterns, habits) come from engine exports, never hardcoded in copy
• JSONB-first — new fields land in profiles.onboarding_data or protocol_json.diagnostic, no SQL migration needed
• Soft delete — deleted_at IS NULL filter on profiles/protocols/blood_tests; CASCADE handles full account delete
• SWR everywhere — useMyData(), useStatistics(), useProtocolHistory() etc. in lib/hooks/useApiData.ts
• Section + metric-tile + glass-card + pill- + 9×9 accent-bg icons* — design system primitives, used uniformly across dashboard / settings / history / stats / chat / tracking
