• Tests
  • Add H2 test profile config for stable backend tests
  • Add targeted blockchain service tests for SQL expiry and verify-episode behavior
• Validation
  • Run backend compile
  • Run backend tests

Original prompt

Implement MediChain V2 foundational features in repository CodeVoyager3/MediChain with backend in /backend (Spring Boot) and frontend in /frontend (React).

Objective:
Create a new feature branch, implement core V2 capabilities with a demo-first approach, and open a pull request.

Scope (in priority order):

1. Episodes of Care backend foundation
2. Frontend Trust Score display from existing verify-record booleans
3. Basic episode UI integration in doctor/patient flows

Detailed requirements:

Backend (/backend):
A. Database changes

• Add a new table episodes with columns:
  • episode_id (auto-increment primary key)
  • patient_address (FK to users.wallet_address)
  • title (required)
  • description (nullable)
  • created_by (FK to users.wallet_address)
  • created_at (default now)
• Add nullable FK column episode_id to medical_records referencing episodes(episode_id).
• Use project’s existing migration mechanism and naming conventions.

B. API endpoints

• Add POST /api/doctor/create-episode
  • Auth: doctor JWT required
  • Input: patientAddress, title, description(optional)
  • Behavior: create episode row with created_by from JWT wallet; return created episode (or at least episode_id + metadata).
• Update existing POST /api/doctor/mint-record
  • Accept optional episode_id
  • If provided, persist linkage to medical_records.episode_id
  • Preserve backwards compatibility when omitted.
• Add GET /api/patient/episodes
  • Auth: patient JWT required
  • Return all episodes for JWT patient with nested records grouped under each episode
  • Include an “ungrouped” section for records where episode_id is null (or equivalent response field)

C. Backend quality

• Keep changes non-breaking for existing V1 flows.
• Follow existing error response style; if project has a standard error DTO, use it.
• Add/adjust repository/service/controller layers consistent with current architecture.

Frontend (/frontend):
A. Trust Score on insurer dashboard

• Based on existing verify-record response booleans:
  • providerVerified => +40
  • integrityValid => +40
  • isLatestVersion => +20 if true, else +10
• Render numeric score and badge:
  • 90-100 HIGH (green)
  • 60-89 MEDIUM (yellow)
  • 0-59 LOW (red)
• Show short reason text for failed checks.

B. Doctor episode creation + mint linkage (minimal viable UX)

• Add a “New Episode” action in doctor UI to call /api/doctor/create-episode.
• In mint record flow, add optional episode selector/input so mint request can include episode_id.

C. Patient vault grouped episodes view

• Add episode-oriented rendering using /api/patient/episodes response.
• Include visible “Ungrouped Records” section.

Engineering constraints:

• Keep styling consistent with existing Tailwind/React patterns.
• Avoid broad refactors unrelated to this scope.
• Ensure frontend API calls use existing auth/JWT mechanisms.
• If exact existing endpoint names differ slightly, adapt to repo conventions while preserving intent.

Deliverables:

• New branch with all changes committed.
• Open PR into main with a clear summary, testing notes, and any migration notes.
• In PR description, include:
  • Implemented endpoints and payloads
  • DB migration details
  • UI changes and Trust Score logic
  • Manual test checklist

Repository: CodeVoyager3/MediChain
Base branch: main

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: now i want you to initialize working on our project and help me through

Assistant: Absolutely — great, I’m in.
Let’s start by turning this into an execution plan and begin immediately.

What I’ll do with you

I’ll act like your technical pair-programmer/project lead for MediChain V2 and guide you step-by-step from “where you are now” → “Round 2 demo-ready build.”

Step 0 (right now): confirm the repo + branch

I’ll work against:

• Repo: CodeVoyager3/MediChain
• Please tell me the main working branch (e.g., main, dev, v2).

Recommended start order (fastest path to demo value)

1. Episodes of Care backend (DB + endpoints)
2. Patient Vault grouped by episodes (frontend)
3. Doctor mint flow with optional episode_id
4. Insurer Trust Score UI (from existing verify-record booleans)
5. QR generation + scan for insurer/patient/doctor

This gives a very strong demo quickly before advanced AI/rule engine layers.

Immediate action plan (today)

1) Backend migration (first coding task)

Create migration for:

• episodes table
• medical_records.episode_id nullable FK

2) Backend episode APIs

Implement:

• POST /api/doctor/create-episode
• GET /api/patient/episodes (grouped payload)
• Update POST /api/doctor/mint-record to accept optional episode_id

3) Frontend minimal integration

• Add “New Episode” form in doctor dashboard
• Add episode dropdown in mint form
• Add patient vault grouped accordion view
