# CYFER: Governance Edition — Phase Task Breakdown

## Timeline: March 16 - March 22, 2026 (6 Days)

**Team Size:** 4 members
**Video Deadline:** March 22, 2026 (11:59 PM)
**GitHub Repo:** Must be public before submission
**Challenge:** #3 — Transparency, Accountability, and Good Governance

---

## Hackathon Judging Criteria & How CYFER Addresses Each

| Criterion | Weight | How CYFER Addresses It |
|-----------|--------|------------------------|
| **Mastery and Use of Software Concepts** | 30% | Custom SHA-256 blockchain, UCP consensus protocol, Next.js App Router, Supabase with RLS, Anthropic Claude AI API, TypeScript strict typing, server-side security |
| **Novelty and Innovation** | 30% | Blockchain-backed document verification for LGUs is rare in PH gov tech. UCP (unanimous multi-official approval) is a novel accountability mechanism. AI summarizer bridges the literacy gap for citizens. |
| **Real-world Impact and Viability** | 30% | Targets city/municipal LGUs in the Philippines. Directly addresses document tampering, lack of transparency, and single-point-of-failure publishing. Deployable on Vercel + Supabase free tier. SDG 16 aligned. |
| **Compliance to Rules and Restrictions** | 10% | Must disclose AI use (Anthropic Claude API). Video 3-5 min. Public GitHub repo. Working prototype demonstrated (not slides-only). |

## Video Requirements Checklist (Due March 22, 11:59 PM)
- [ ] 3-5 minutes (strictly enforced — deductions for violations)
- [ ] Demonstrates working prototype (not slides-only)
- [ ] Explains the **problem** (corruption, document tampering, lack of transparency in PH LGUs)
- [ ] Explains the **solution** (CYFER — blockchain verification, UCP, AI summarizer)
- [ ] Shows **real-world application** (city/municipal government use case)
- [ ] **Clearly states all technologies used:**
  - Languages: TypeScript, SQL
  - Framework: Next.js 14+ (App Router)
  - Styling: Tailwind CSS

## Key Selling Points to Emphasize in Video
1. **Tamper-proof** — SHA-256 hash stored on custom blockchain. Any modification is instantly detectable.
2. **Unanimous Consensus** — No single official can unilaterally publish. All must approve.
3. **AI Accessibility** — Complex ordinances/budgets summarized in plain language for citizens.
4. **Public Verifiability** — Anyone can verify any document with no account needed.
5. **SDG 16 alignment** — Peace, Justice and Strong Institutions.

## Phase 4: Integration & Polish (Day 4 — March 19)

### Infrastructure Completed (March 17) ✅
- [x] ✅ Supabase project created (Singapore region, free tier)
- [x] ✅ Database schema deployed (`001_initial_schema.sql` — all 6 tables)
- [x] ✅ RLS policies applied (`001_rls_policies.sql` + `002_security_fixes.sql`)
- [x] ✅ Supabase Auth configured (email provider, confirm email OFF)
- [x] ✅ Storage bucket `documents` created (public, 50MB, 2 policies)
- [x] ✅ `.env.local` configured with Supabase URL, anon key, service role key, Anthropic key
- [x] ✅ Blockchain hash bug fixed in `lib/blockchain.ts`:
  - Timestamps normalized to Unix ms (JS ISO string ≠ Supabase-returned format)
  - JSON keys sorted before hashing (PostgreSQL JSONB doesn't preserve insertion order)
- [x] ✅ Production build verified — 26 routes compiled, 0 errors
- [x] ✅ All tests passing (`test-supabase.ts` — connection, tables, blockchain validation)

### ⚠️ Known Issues & Lessons Learned (IMPORTANT for Phase 4)

#### 1. Auth Users — Do NOT use seed SQL to create auth.users
The seed SQL (`001_demo_data.sql`) attempts to insert directly into `auth.users` and `auth.identities` with hardcoded UUIDs. **This does not work reliably.** The Supabase new secret key format (`sb_secret_*`) also does not support `auth.admin.*` API methods.

**What actually worked:** Create auth users manually in Supabase Dashboard → Authentication → Users → Add User (with "Auto Confirm User" checked).

**Current admin credentials:**
| Role | Email | Password | Auth UUID |
|------|-------|----------|-----------|
| Super Admin | `[email protected]` | `DemoPassword123!` | `d471eda7-f4a7-42ab-b835-541756fce3e3` |
| Admin | `[email protected]` | `DemoPassword123!` | `159291dd-7701-4264-995b-6e31295bf930` |
| Admin | `[email protected]` | `DemoPassword123!` | `c28d6485-36a0-42ef-b144-6ebf4fab3ad0` |

`public.users` table has been synced with these real auth UUIDs.

#### 2. RLS Infinite Recursion on public.users
The `Super admins can manage users` RLS policy queries `public.users` to check role. When a client that has called `signInWithPassword()` tries to write to `public.users`, the policy evaluates and queries the same table → infinite recursion.

**Fix:** Always use a **separate** Supabase client instance for DB writes after calling auth methods. The session from `signInWithPassword` contaminates the client's subsequent requests.

**In API routes:** `createServerClient()` (service role key) bypasses RLS entirely — this is correct and will work fine. The issue only occurs in scripts that mix auth + DB operations on the same client.

#### 3. Sample Document & Budget Data — uploaded_by is NULL
During the auth user cleanup, `documents.uploaded_by` and `budget_data.uploaded_by` were set to NULL to clear FK constraints. The sample data still exists but has no uploader linked.

**Action needed in Task 4.5:** Re-seed proper demo documents with correct uploaded_by UUIDs (use the real UUIDs above, not the old hardcoded ones).

#### 4. Service Role Key Format
Supabase now issues `sb_secret_*` format secret keys instead of JWT format. This key works for all database operations via `supabase-js`, but **does NOT work** with `supabase.auth.admin.*` methods. For admin auth operations, use the Supabase Dashboard directly.

### Task 4.1: Connect Frontend to Backend
- [x] ✅ Wire all public pages to their respective API endpoints (already wired from Phase 2/3)
- [x] ✅ Wire all admin pages to their respective API endpoints (already wired from Phase 2/3)
- [x] ✅ Fix: Verify API now returns `fileHash` in response to match frontend expectations
- [x] ✅ Fix: Users page data access corrected (`json.data` instead of `json.data.user`)
- [x] ✅ Fix: Admin dashboard now shows correct published count (separate API call for published vs total)
- [x] ✅ Fix: Admin layout now has client-side auth guard (redirects to `/login` if no token)
- [x] ✅ Fix: `VerificationResult` type updated to include `fileHash` field
- [x] ✅ Production build verified — 28 routes compiled, 0 errors
- [x] ✅ Fix `uploaded_by = NULL` — updated 1 document + 8 budget entries with mayor UUID
- [x] ✅ Test complete flows end-to-end:
  - [x] ✅ Admin login → upload document → other admins approve → document appears on public portal
  - [x] ✅ Citizen clicks "AI Summary" on a published document → summary generates correctly (AI summarization route now extracts file content from Supabase Storage with best-effort PDF/DOCX/TXT parsing)
  - [x] ✅ Citizen verifies document → verified result (with fileHash displayed)

## Task Assignment Suggestion (4 Members)

| Member | Primary Focus | Key Tasks |
|--------|--------------|-----------|
| Member 1 (Francis Gabriel) | Full-stack lead / Backend | Phase 0 setup, Phase 1 APIs (documents, blockchain, verification), Phase 4 integration |
| Member 2 (Om Shanti) | Frontend lead | Phase 2 public pages (portal, verify, budget, audit), Phase 4 UI polish |
| Member 3 | Backend + Database | Phase 0 Supabase setup, Phase 1 APIs (consensus, audit, budget, auth), Phase 4 demo data |
| Member 4 | Frontend + Video | Phase 3 admin pages, Phase 2 landing page, Phase 5 video script, Phase 6 recording/editing |

**Daily Standups:** Quick 10-minute sync at start of each day to review progress and blockers.

---

## Risk Mitigation

| Risk | Mitigation |
|------|------------|
| Supabase setup takes too long | Fall back to local SQLite with Prisma |
| Team member unavailable | Each member has a buddy who understands their tasks |
| Feature not ready in time | Cut budget dashboard first (least critical for demo), then audit trail |
| Video quality issues | Record backup takes, keep video simple with screen recording + voiceover |
| Deployment fails | Demo from localhost — still valid as working prototype |

---

## Feature Priority (If Running Out of Time)

1. **MUST HAVE:** Document upload + hashing + verification + tamper detection (this IS the demo)
2. **MUST HAVE:** UCP approval workflow (this is the differentiator)
3. **SHOULD HAVE:** AI Document Summarizer
4. **SHOULD HAVE:** Audit trail / transaction chain
5. **NICE TO HAVE:** Budget transparency dashboard
6. **NICE TO HAVE:** Polished landing page with animations
