+# Decision Log
+
+Audit trail of all major decisions in TokenVotingUtil collaboration. This file is **local** (not in GitHub) and tracks thinking for future reference.
+
+---
+
+## 2026-02-25: Reset ADN — Establish Healthy Collaboration Framework
+
+### Question
+How do we structure long-term collaboration with sollama58 (volunteer maintainer) in a way that scales and doesn't require constant re-alignment?
+
+### Options Considered
+
+**Option A: Prescriptive** (Bad)
+- We code fixes locally
+- Push PRs with changes already made
+- Wait for feedback / approval
+- Con: Surprises sollama58, doesn't respect his bandwidth
+
+**Option B: Collaborative with Governance** (Chosen)
+- We propose ideas in Issues first
+- sollama58 provides feedback (async)
+- We code based on his decision
+- Decisions documented for future reference
+- Pro: Transparent, respectful, scalable
+
+**Option C: No Structure** (Worst)
+- Ad-hoc communication
+- Decisions scattered in Slack/Discord
+- Hard to track what was decided and why
+- Con: Knowledge loss, repeating conversations
+
+### Decision
+**Chosen: Option B** (Collaborative with Governance)
+
+### Implementation
+1. Create governance documents:
+   - `COLLABORATION.md` — How we work together
+   - `ARCHITECTURE.md` — Technical overview + known issues
+   - `ROADMAP.md` — Phases 1-3 with decision points
+   - `.claude/decisions.md` — This file (local audit trail)
+
+2. Structure Phase 1 as two étapes:
+   - Étape 1: Infrastructure hardening (ready to merge now)
+   - Étape 2: Voting logic (blocked on decision)
+
+3. Open GitHub Issue #1:
+   - Propose Phase 1 roadmap
+   - Ask sollama58 for feedback on Phase 1 Étape 2 (3 paths: A/B/C)
+   - Get explicit decision before coding
+
+4. Open GitHub PR #1:
+   - Tier 1 gaps (CORS, tests, logging, Redis)
+   - Reference Issue #1
+   - Link to DEPLOYMENT.md and ARCHITECTURE.md
+
+### Rationale
+- **Transparent**: All plans visible to sollama58 before we code
+- **Respectful**: Doesn't force decisions on him
+- **Scalable**: Structure repeats for Phase 2, 3, etc.
+- **Documented**: Future collaborators understand the why
+- **Async-friendly**: Works with volunteer's sporadic availability
+
+### Blocked By
+Nothing. This is foundational.
+
+### Outcome
+- 4 governance docs created (COLLABORATION, ARCHITECTURE, ROADMAP, this file)
+- Clear decision framework for Phase 1 Étape 2
+- GitHub Issue #1 ready to open (waits for user approval)
+- GitHub PR #1 structured properly (references Issue #1, DEPLOYMENT, ARCHITECTURE)
+
+### Next Decision Needed
+sollama58's response to Issue #1:
+- Approve Phase 1 Étape 1 for merge?
+- Which path for Phase 1 Étape 2? (A: quick fixes, B: full backend, C: defer)
+- Timeline preferences?
+
+---
+
+## 2026-02-24: Infrastructure Fixes (Phase 1 Étape 1)
+
+### Question
+What are the critical infrastructure gaps in TokenVotingUtil that block production deployment?
+
+### Decision
+Identified 4 Tier 1 gaps:
+1. CORS vulnerability (open to any origin)
+2. Zero test suite
+3. No structured logging
+4. In-memory rate limiting (doesn't survive restart)
+
+### Implementation
+5 atomic commits on `dev/gaps-tier1`:
+1. `8cd5f42` — CORS allowlist + CSP hardening
+2. `3f25631` — Jest test suite (20 tests)
+3. `adc70af` — Winston structured logging
+4. `79da4da` — Redis-backed rate limiter
+5. `6b0cba5` — Documentation + integration tests
+
+### Testing
+- All 34 tests pass (unit + integration)
+- Manual verification of each fix
+- Code coverage: 9.82% (API surface)
+
+### Outcome
+Phase 1 Étape 1 ready for sollama58 review and merge.
+
+---
+
+## 2026-02-24: Voting Logic Audit
+
+### Question
+Are there bugs in the voting logic that would break governance?
+
+### Findings
+Identified 6 issues:
+
+**Critical**:
+1. Margin >= threshold (should be >)
+2. Frontend tally authority (no server verification)
+
+**Medium**:
+3. No tie detection
+4. Voting power TOCTOU risk
+5. Vote recalculation not enforced
+
+**Low**:
+6. Zero pool edge case (handled, but untested)
+
+### Decision
+3 critical/medium issues warrant Phase 1 Étape 2 work:
+1. Fix margin bug (30 min, low risk)
+2. Add tie detection (30 min, low risk)
+3. Backend tally authority (architectural, needs sollama58 input)
+
+### Blocked By
+sollama58's decision on Path A/B/C (see ROADMAP.md)
+
+---
+
+## Future Decisions Needed
+
+### 2026-02-25 (Pending)
+**Issue #1: Phase 1 Roadmap**
+- Q: Which path for voting fixes? (A: quick, B: full backend, C: defer)
+- Q: Timeline for Phase 1 Étape 1 merge?
+- Q: Timeline for Phase 1 Étape 2?
+- Q: Any other Phase 1 priorities?
+
+### 2026-03-XX (Estimated, pending Phase 1)
+**Phase 1 Complete**
+- Decide on Phase 2 timeline
+- Assess multi-tenant needs
+- Plan scaling strategy
+
+### 2026-04-XX (Estimated, pending Phase 2)
+**Phase 2 Complete**
+- Decide if Phase 3 (advanced features) needed
+- Assess governance launch readiness
+- Plan community outreach
+
+---
+
+## Decision Tracking Format
+
+When a new decision is needed:
+1. Open GitHub Issue with clear question
+2. Document options (with pros/cons)
+3. Ask for explicit decision
+4. Update this file when sollama58 responds
+5. Reference decision in code comments / commits
+
+---
+
+## Notes on Collaboration Style
+
+**Lessons Learned** (from this reset):
+- Don't code solutions before asking questions
+- Don't assume what the maintainer wants
+- Don't hide decisions in commit messages
+- Don't open PRs without context (link to issue)
+- Don't skip documentation
+
+**This Prevents**:
+- "Why did you do this?" conversations
+- Re-doing work because we misunderstood
+- Losing context when decisions are made
+- Knowledge silos (one person knows why)
+
+**This Enables**:
+- Scaling collaboration (works with any maintainer)
+- Async work (no real-time sync needed)
+- Long-term sustainability (future contributors understand)
+- Trust building (transparent process)
+
+---
+
+## Review & Refinement
+
+This document is **living**. Update it as:
+- New decisions are made
+- Outcomes are known
+- Process is refined based on sollama58's feedback
+
+**Questions about this workflow?** Open an issue or ask sollama58 for feedback.

+# Architecture Overview
+
+TokenVotingUtil is a Solana lock verifier + governance platform. This document explains the design, current state, and constraints.
+
+## High-Level Purpose
+
+**Lock Verifier**:
+- Display all locked tokens for a given Solana SPL token mint
+- Show lock details, unlock timelines, lock names
+- Cache data from Streamflow (avoid RPC rate limits)
+
+**Governance Platform**:
+- Create proposals (weighted by token holdings)
+- Vote with two modes: locked-only or all-holders
+- Tally results with configurable thresholds
+- Embeddable on Squarespace (iframe)
+
+## Technology Stack
+
+| Layer | Tech | Notes |
+|-------|------|-------|
+| **Frontend** | Vanilla HTML/CSS/JS | Single file: `public/index.html` (3KB+) |
+| **Backend** | Node.js + Express | ~400 LOC in `server.js` |
+| **Database** | PostgreSQL | Caches lock data + proposal/vote records |
+| **Blockchain** | Solana + Streamflow | RPC calls via `@solana/web3.js` + `@streamflow/stream` |
+| **Cache Layer** | PostgreSQL + In-Memory | Avoid Solana RPC rate limits (300s TTL) |
+| **Rate Limiting** | Redis (with fallback) | Distributed rate limiting across instances |
+| **Logging** | Winston | Structured logging (console + file) |
+
+## Modules
+
+### `server.js` (405 LOC)
+Main Express app. Routes:
+- `GET /api/locks` — Fetch all lock data
+- `POST /api/proposals` — Create proposal
+- `GET /api/proposals` — List proposals
+- `POST /api/proposals/:id/vote` — Cast vote
+- `POST /api/locks/:id/name` — Rename lock
+- Admin endpoints (protected by password)
+
+**Middleware**:
+- CORS allowlist (via `ALLOWED_ORIGINS` env var)
+- CSP headers (`frame-ancestors` restriction)
+- Rate limiter (Redis-backed)
+- JSON parser (16KB limit)
+
+### `streamflow.js` (380 LOC)
+Blockchain integration:
+- `fetchLockData()` — Query Streamflow API for locks
+- `getWalletTokenBalance()` — Fetch wallet SPL token balance
+- `refreshData()` — Periodic background refresh
+- Cache management (in-memory + PostgreSQL)
+
+### `db.js` (173 LOC)
+PostgreSQL integration:
+- Proposal CRUD (create, read, list, delete)
+- Vote operations (insert, query, delete)
+- Lock name overrides (setName, deleteName)
+- Stats (getStats)
+
+**Tables**:
+- `proposals` (id, title, choices, threshold, vote_mode, ends_at, created_at)
+- `votes` (proposal_id, wallet, choice_index, voting_power)
+- `lock_names` (lock_id, name, set_by, set_at)
+
+### `logger.js` (50 LOC)
+Winston structured logging:
+- Console output (dev): colored, human-readable
+- File output (prod): JSON, for log aggregation
+- Levels: debug, info, warn, error
+- Metadata support (userId, action, reason, etc.)
+
+### `rate-limiter.js` (159 LOC)
+Distributed rate limiting:
+- Redis sorted sets for tracking requests
+- Fallback to in-memory if Redis unavailable
+- RFC 6585 compliant headers (X-RateLimit-*)
+- Graceful shutdown
+
+### `public/index.html` (3100+ LOC)
+Single-page frontend:
+- Lock dashboard (summary, stats, timeline)
+- Lock browser (sortable/filterable table)
+- Proposal creation + voting UI
+- Admin panel (password-protected)
+- Wallet connection (Phantom, Solflare, etc.)
+- Vote tallying logic (client-side)
+
+---
+
+## Current Issues & Constraints
+
+### Known Bugs (Tier 2)
+
+1. **Margin Comparison Bug**
+   - Location: `public/index.html:1536`
+   - Issue: `margin >= threshold` should be `margin > threshold`
+   - Impact: Proposals pass when margin equals threshold (should exceed)
+   - Risk: HIGH (affects governance integrity)
+
+2. **Frontend Tally Authority**
+   - Location: `public/index.html` (entire tallyProposal function)
+   - Issue: Results calculated client-side only, no server verification
+   - Impact: Tally could be manipulated or inconsistent across clients
+   - Risk: HIGH (governance authority unclear)
+
+3. **Tie Detection**
+   - Location: `public/index.html:2050`
+   - Issue: No explicit handling when two choices have equal votes
+   - Impact: Silent tie-breaking by array order (non-deterministic)
+   - Risk: MEDIUM (edge case, but affects proposal legitimacy)
+
+### Design Constraints
+
+**Frontend-Based Voting Tally**:
+- Currently: Frontend aggregates votes, calculates winner
+- Pro: Reduces server load
+- Con: No authoritative source of truth; can't easily audit
+
+**No Voting Logic Tests**:
+- Unit tests cover modules, not voting math
+- Integration tests needed for edge cases
+
+**In-Memory Rate Limiting Fallback**:
+- If Redis unavailable, falls back to in-memory
+- Resets on app restart (acceptable for now)
+
+### Deployment Constraints
+
+**Render Limitations**:
+- Ephemeral filesystem (logs deleted on redeploy)
+- No persistent Redis on free tier
+- Node.js only (no compiled languages)
+
+**Solana RPC Limits**:
+- Public RPC has strict rate limits
+- Requires dedicated provider (Helius, QuickNode)
+- Caching essential (300s TTL default)
+
+---
+

+# Collaboration Workflow
+
+This document defines how we collaborate on TokenVotingUtil — transparently, asynchronously, and with clear decision-making.
+
+## Principles
+
+1. **Async-First**: All major communication via GitHub Issues/PRs (not Slack)
+2. **Transparent**: Decisions documented, not hidden in commit messages
+3. **Incremental**: Small, reviewable PRs; no big surprise refactors
+4. **Respectful**: Adapt to maintainer's bandwidth and vision
+5. **Traceable**: All decisions logged for future reference
+
+---
+
+## Communication Channels
+
+### Issues (Questions, Decisions, Blockers)
+
+Use issues for:
+- Questions that need answers before coding
+- Proposals for major changes
+- Blockers that need decision-making
+- Feature requests / design discussions
+
+**Labels** (recommended):
+- `needs-feedback`: Waiting for sollama58's response
+- `decision-needed`: Multiple options, need approval before proceeding
+- `blocked-by-design`: Architectural question, blocks implementation
+- `phase-1`, `phase-2`, `phase-3`: Phase tracking
+
+**Response Time**: Expect 2-3 days (realistic for volunteer maintainer)
+
+### Pull Requests (Solutions)
+
+Use PRs for:
+- Implementing approved solutions
+- Showing concrete code + tests
+- Ready to merge OR request changes
+
+**Guidelines**:
+- One feature/fix per PR (atomic, independent)
+- Detailed description: why, what, testing, risks
+- Link to related issue (`Closes #X` or `Related to #Y`)
+- No force-push after review started
+- Can merge after approval OR fix feedback
+
+**Review Checklist**:
+- [ ] Code style consistent with project
+- [ ] Tests pass locally
+- [ ] No breaking changes to existing API
+- [ ] Deployment notes followed (if applicable)
+
+### Discussions (Real-Time Collaboration)
+
+Use GitHub Discussions if:
+- You need a real-time conversation (rare)
+- Complex design decision needs back-and-forth
+- Post summary in issue when done (archive the conversation)
+
+---
+
+## Decision Log
+
+All major decisions documented in `.claude/decisions.md` (this repo) and tracked in GitHub Issues.
+
+**Decision Structure**:
+```
+### YYYY-MM-DD: [Title]
+
+**Question**: What were we deciding?
+**Options**: A, B, C (with pros/cons)
+**Decision**: We chose option X
+**Rationale**: Why X makes sense
+**Outcome**: What we implemented
+**Blocked By**: Any dependencies
+```
+
+---
+
+## Phase Structure
+
+See `ROADMAP.md` for complete roadmap.
+
+**Phase 1 (Current)**: Stabilize & Harden
+- Infrastructure fixes (CORS, tests, logging, rate limiting)
+- Voting logic audit
+- Bug fixes
+
+**Phase 2**: Production Ready
+- Fix identified bugs
+- Backend voting authority (if approved)
+- Config externalization
+
+**Phase 3**: Scale & Enhance
+- Multi-tenant support
+- Leaderboard / XP system
+- Advanced governance features
+
+---
+
+## What Success Looks Like
+
+✓ sollama58 can easily understand what we're proposing
+✓ No surprises — all changes announced in issues first
+✓ PRs are easy to review (one feature, clear testing)
+✓ Decisions are traceable (why did we do this?)
+✓ Project can be maintained independently without our help
+
+---
+
+## Current Status
+
+**Phase 1 - Étape 1: Infrastructure Fixes**
+- [ ] Issue #1 opened: "Phase 1 Roadmap"
+- [ ] PR #1 opened: "Tier 1 gaps (CORS + tests + logging + Redis)"
+- [ ] Awaiting sollama58 feedback
+
+**Phase 1 - Étape 2: Voting Logic Fixes**
+- [ ] Issue #2 opened: "Voting Logic Audit" (if needed after Issue #1 response)
+- [ ] Awaiting decision on bug fixes
+- [ ] Implementation pending approval
+
+---
+
+## Questions?
+
+If anything in this workflow is unclear, open an issue. We can discuss and adjust.
+
+**Goal**: Make collaboration smooth for everyone.

+# Deployment Checklist
+
+This document provides step-by-step instructions for deploying TokenVotingUtil to production.
+
+## Local Development Setup
+
+### Prerequisites
+- Node.js >= 18
+- PostgreSQL (local or remote)
+- Redis (optional; falls back to in-memory)
+
+### Installation
+
+```bash
+# Clone and install
+git clone <your-fork-url>
+cd TokenVotingUtil
+npm install
+
+# Create environment file
+cp .env.example .env
+
+# Edit .env with your local configuration
+nano .env
+
+# Create logs directory (for production file logging)
+mkdir -p logs
+
+# Start development server
+npm run dev
+```
+
+### Local Testing
+
+```bash
+# Run test suite
+npm test
+
+# Start server (will auto-reload on file changes)
+npm run dev
+
+# In another terminal, test the API
+curl http://localhost:3000/api/health
+curl http://localhost:3000/api/locks
+```
+
+## Render Deployment
+
+### Step 1: Provision Resources
+
+1. **PostgreSQL Database**
+   - In Render Dashboard: New > PostgreSQL
+   - Name: `lockverifier-db`
+   - Region: Oregon (or your preference)
+   - Render will auto-provide `DATABASE_URL` env var
+
+2. **Redis (Optional but Recommended)**
+   - In Render Dashboard: New > Redis
+   - Name: `lockverifier-redis`
+   - Region: Same as PostgreSQL
+   - Render will auto-provide `REDIS_URL` env var
+
+### Step 2: Set Environment Variables
+
+In Render Dashboard, go to your web service's **Environment** tab and set:
+
+| Variable | Value | Required |
+|----------|-------|----------|
+| `SOLANA_RPC_URL` | Your Helius/QuickNode RPC endpoint | ✓ |
+| `ADMIN_PASSWORD` | Strong password for admin panel | ✓ |
+| `ALLOWED_ORIGINS` | Your domain(s): `https://yourdomain.com,https://www.yourdomain.com` | ✓ |
+| `TOKEN_MINT` | `9zB5wRarXMj86MymwLumSKA1Dx35zPqqKfcZtK1Spump` | ✓ |
+| `PORT` | `3000` (Render sets this automatically) | — |
+| `CACHE_TTL_SECONDS` | `300` (or your preference) | — |
+| `TOKEN_DECIMALS` | `6` | — |
+| `SITE_TITLE` | `ASDelegate` (or your site name) | — |
+| `LOG_LEVEL` | `info` (or `debug`/`warn`/`error`) | — |
+| `NODE_ENV` | `production` | — |
+
+**Note**: `DATABASE_URL` and `REDIS_URL` are auto-set by Render if you provisioned them via blueprint or manual creation.
+
+### Step 3: Build and Deploy
+
+If using `render.yaml` blueprint:
+1. Push code to GitHub
+2. In Render: New > Blueprint
+3. Connect your GitHub repo
+4. Render reads `render.yaml` and creates web service + PostgreSQL
+5. Review environment variables (from Step 2)
+6. Click **Deploy**
+
+If manual deploy:
+1. Create web service in Render
+2. Connect GitHub repo + branch
+3. Build command: `npm install`
+4. Start command: `npm start`
+5. Set environment variables (Step 2)
+6. Deploy
+
+### Step 4: Verify Deployment
+
+Once deployed, test the live app:
+
+```bash
+# Health check
+curl https://<your-service>.onrender.com/api/health
+
+# Fetch locks
+curl https://<your-service>.onrender.com/api/locks
+
+# Check admin panel password (should return 200 or 401)
+curl -X POST https://<your-service>.onrender.com/api/admin/auth \
+  -H "Content-Type: application/json" \
+  -d '{"password":"your-admin-password"}'
+```
+
+### Step 5: Monitor Logs
+
+In Render Dashboard, go to **Logs** to check:
+- Application startup (should see "Server running on port 3000")
+- Database connection (should see "Database initialized")
+- Redis connection (should see "Redis connected" or "Redis not available, falling back to in-memory")
+- Any errors during operation
+
+## Common Issues
+
+### CORS Errors on Embedded Iframe
+
+**Problem**: Iframe on your website gets blocked.
+
+**Solution**:
+1. Ensure `ALLOWED_ORIGINS` includes your domain
+2. Test with curl: `curl -H "Origin: https://yourdomain.com" https://<service>.onrender.com/api/locks`
+3. Should see `Access-Control-Allow-Origin: https://yourdomain.com` in response headers
+
+### Rate Limiting Blocked Requests
+
+**Problem**: Users get 429 (Too Many Requests) errors.
+
+**Solution**:
+1. Verify Redis is provisioned and `REDIS_URL` is set
+2. Check logs: should see "Redis connected" or "falling back to in-memory"
+3. Rate limits: 30 seconds for refresh, 60 seconds for voting
+4. If in-memory fallback: restarting the app resets rate limits
+
+### File Logging Fails in Production
+
+**Problem**: `logs/error.log` and `logs/combined.log` don't appear.
+
+**Solution**:
+1. Render auto-creates the `logs/` directory during build
+2. Check logs in Render dashboard (not local files)
+3. Logs are ephemeral on Render; use external log aggregation for persistent logs
+
+### Redis Connection Timeout
+
+**Problem**: Service hangs during startup.
+
+**Solution**:
+1. Verify `REDIS_URL` is correct
+2. Ensure Redis instance is running
+3. App will timeout and fall back to in-memory (check logs)
+4. For production reliability, provision Redis through Render
+
+## Rollback
+
+If deployment fails:
+1. Go to Render Dashboard > Deployments
+2. Click the previous successful deployment
+3. Click "Redeploy"
+4. The app will roll back to the last known-good state
+
+## Monitoring Checklist
+
+After deployment, verify:
+
+- [ ] Service is running (health check passes)
+- [ ] Database tables created (check Render Postgres logs)
+- [ ] CORS headers present (test with curl)
+- [ ] Rate limiting active (test with rapid requests)
+- [ ] Logging works (check Render logs)
+- [ ] Admin panel accessible (login with admin password)
+- [ ] Can fetch locks from Streamflow
+- [ ] Voting works (create proposal, cast vote, tally works)
+
+## Support
+
+For issues:
+1. Check Render logs first (Logs tab)
+2. Test locally with same `.env` variables
+3. Verify all required environment variables are set
+4. Check PostgreSQL and Redis connections

+**Security**: Wallet signature verification is missing. Without it, anyone can impersonate any wallet and vote as them. This is a **governance killer** and must be fixed before any real governance launch.
+
+**Logic**: 3 voting bugs identified (margin >=, tie detection, tally authority). Two are fixable in 30 min each. One requires architectural change.
+
+**Operational**: Missing structured logging, graceful shutdown gaps, health check too simplistic.
+
+**Architecture**: Schema migrations run on every boot, no transaction handling, results not persisted.
+
+**Verdict**: UX + blockchain parsing solid. Core security gap blocks production. Otherwise incremental fixes.

+
+## CRITICAL ISSUES (2)
+
+### SEC-001: No Wallet Signature Verification
+
+**Severity**: CRITICAL
+**Category**: Security
+**Module**: server.js (all POST routes accepting `wallet`)
+**Tier**: 1
+
+**The Problem**
+Every governance action (create proposal, vote, rename lock) accepts a wallet address in the request body with zero cryptographic proof that the sender controls it.
+
+```js
+// server.js:209 - insecure
+const { wallet, choiceIndex } = req.body;
+await insertVote(proposalId, wallet, choiceIndex, votingPower);
+```
+
+**Impact**
+A curl command can vote as any wallet:
+```bash
+curl -X POST http://localhost:3000/api/proposals/123/vote \
+  -H "Content-Type: application/json" \
+  -d '{"wallet":"FakeWallet123...","choiceIndex":0}'
+# Vote recorded as FakeWallet, with their real voting power
+```
+
+The entire governance layer is spoofable.
+
+**Expected**
+Caller signs a message with their private key (using `@solana/web3.js`). Backend verifies signature using `nacl.sign.detached.verify()`.
+
+```js
+// Proposed fix
+const { wallet, message, signature } = req.body;
+const isValid = nacl.sign.detached.verify(
+  Buffer.from(message),
+  Buffer.from(signature, 'base64'),
+  new PublicKey(wallet).toBytes()
+);
+if (!isValid) return res.status(401).json({ error: "Invalid signature" });
+```
+
+**Effort**: 2h (backend nonce + verification) + 30min frontend (sign before each action)
+**Blocker**: Decision on nonce strategy (per-action vs session-based)
+**Phase**: Tier 1 (must fix before governance launch)
+
+---
+
+### SEC-002: Admin Password in Plaintext, Stored in JS Memory
+
+**Severity**: CRITICAL
+**Category**: Security
+**Module**: server.js:290, index.html:2711
+**Tier**: 1
+
+**The Problem**
+Admin password is sent in request body and stored in browser memory as a JS global variable. It's visible via DevTools, and reused as the `x-admin-key` header on every subsequent admin request.
+
+```js
+// index.html:2711
+adminKey = pw;  // plain password stored in window scope
+// index.html:2712 (every admin call)
+headers["x-admin-key"] = adminKey;  // password in header
+```
+
+**Impact**
+Browser DevTools → Application → JavaScript memory → `adminKey = "correct-horse-battery-staple"` exposed. If anyone gains browser access (malware, MITM), the admin password is compromised.
+
+**Expected**
+Use JWT or session cookie. Backend issues a token after successful auth. Frontend stores token (not password) and sends token in header.
+
+```js
+// Proposed: Auth endpoint returns token
+POST /api/admin/auth
+{ "password": "..." }
+→ { "token": "eyJhbGciOiJIUzI1NiIs..." }
+
+// Store token in memory or secure httpOnly cookie
+// Send token in header (not password)
+headers["x-admin-token"] = token;
+```
+
+**Effort**: 2h (JWT issuance + verification, replace header logic)
+**Blocker**: None
+**Phase**: Tier 1 (must fix before production)
+
+---
+
+## HIGH SEVERITY ISSUES (6)
+
+### BUG-001: Margin >= Threshold (Should Be >)
+
+**Severity**: HIGH
+**Category**: Logic
+**Module**: index.html:1536
+**Tier**: 1 (identified, awaiting sollama58 decision)
+
+**Description**
+`checkThreshold` marks proposal as passed when margin equals threshold, not exceeds it.
+
+```js
+// WRONG
+return { met: margin >= threshold, margin };
+
+// CORRECT
+return { met: margin > threshold, margin };
+```
+
+**Example**
+Threshold = 5%, Margin = 5% → `passed = true` (WRONG, should be false)
+
+**Impact**
+Edge case proposals that barely meet threshold are indistinguishable from those that exceed it. Floating-point rounding on token amounts can flip this check.
+
+**Effort**: 5 min
+**Phase**: Tier 1 (Phase 1 Étape 2, Option A/B/C path)
+
+---
+
+### BUG-002: Frontend is Sole Tally Authority
+
+**Severity**: HIGH
+**Category**: Logic / Architecture
+**Module**: index.html:2033-2051 (no equivalent in backend)
+**Tier**: 1 (identified, Option A/B/C decision)
+
+**Description**
+Proposal results (Passed/Failed) are computed only in frontend JavaScript. Backend has no tally endpoint. Two clients with different data (e.g., different `tokenTotalSupply` snapshots) will compute different results for the same proposal.
+
+```js
+// index.html:2033 - client only
+function tallyProposal(p) {
+  var totals = [0, 0, 0];
+  p.votes.forEach(v => { totals[v.choice_index] += v.voting_power; });
+  var winner = Math.max(...totals);
+  return { passed: checkThreshold(totals, getTotalPool(p.vote_mode), p.threshold) };
+}
+```
+
+No server equivalent exists.
+
+**Impact**
+- Malicious JS modification can falsify results.
+- No canonical result exists for dispute resolution.
+- Audit impossible (no server logs of tally computation).
+
+**Expected**
+Backend `/api/proposals/:id/result` endpoint computes tally server-side, stores immutable result when proposal closes.
+
+**Effort**: 2h (add endpoint, compute server-side, persist result)
+**Phase**: Tier 1 (Option B path from roadmap, or deferred to Phase 2)
+
+---
+
+### BUG-003: TOCTOU on Voting Power
+
+**Severity**: HIGH
+**Category**: Logic
+**Module**: server.js:237-264
+**Tier**: 2
+
+**Description**
+Between `hasVoted()` check and `insertVote()`, no transaction wraps the operation. Concurrent duplicate vote requests could theoretically both pass the `hasVoted` check before either inserts. The PRIMARY KEY constraint catches this at the DB level, but the error is returned as 500 ("Vote failed") instead of 409 ("Already voted").
+
+```js
+// TOCTOU window
+const alreadyVoted = await hasVoted(proposalId, wallet);  // check
+if (alreadyVoted) return res.status(409).json({ error: "Already voted" });
+// ... gap: another identical request can pass the check here
+await insertVote(proposalId, wallet, choiceIndex, votingPower);  // action
+```
+
+**Impact**
+Duplicate vote returns 500 instead of 409, confusing the user. DB constraint prevents actual duplicate, but error handling is wrong.
+
+**Effort**: 30 min (catch unique constraint error specifically, return 409)
+**Phase**: Tier 2
+
+---
+
+### BUG-004: No Tie Detection
+
+**Severity**: HIGH
+**Category**: Logic
+**Module**: index.html:2048-2051
+**Tier**: 2
+
+**Description**
+When two choices have equal voting power, `tallyProposal` shows whichever comes first as "winner" with no indication of a tie.
+
+```js
+// No tie detection
+var winnerIdx = 0;
+totals.forEach(function (t, i) { if (t > totals[winnerIdx]) winnerIdx = i; });
+// winnerIdx now points to first option, silently winning a tie
+```
+
+**Impact**
+Governance results are misleading. 50/50 split shows one option as winner in proposal history.
+
+**Effort**: 30 min
+**Phase**: Tier 2 (Phase 1 Étape 2, Option A/B)
+
+---
+
+### BUG-005: refreshing Flag Not Properly Gated on Cold Start
+
+**Severity**: HIGH
+**Category**: Logic
+**Module**: streamflow.js:278-341
+**Tier**: 2
+
+**Description**
+When multiple concurrent requests hit `fetchLockData()` during cold start (no `memoryCache.data`), the second request sees `refreshing = true` and returns immediately without waiting. If `memoryCache.data` is still empty, it throws "No lock data available yet" (line 380).
+
+```js
+// streamflow.js:278
+if (refreshing) return;  // second request returns immediately
+// streamflow.js:374
+await refreshData();
+if (memoryCache.data) { return ... }
+throw new Error("No lock data available yet");  // second request fails
+```
+
+**Impact**
+During cold start with concurrent load, some requests fail with 503 while others wait. Confuses monitoring and error alerting.
+
+**Effort**: 30 min (return a Promise that waiting callers can await)
+**Phase**: Tier 2
+
+---
+
+### SEC-003: Wallet Address Format Not Validated on Vote/Proposal Routes
+
+**Severity**: HIGH
+**Category**: Security
+**Module**: server.js:149-150, 211-212
+**Tier**: 2
+
+**Description**
+`/api/wallet/:address/balance` validates address format (line 122). But `/api/proposals` (create) and `/api/proposals/:id/vote` only check `typeof wallet !== "string"`. Caller can pass an arbitrary string as wallet.
+
+```js
+// CORRECT (line 122)
+if (!address || !/^[1-9A-HJ-NP-Za-km-z]{32,44}$/.test(address)) { ... }
+
+// MISSING (line 149)
+if (!wallet || typeof wallet !== "string") { ... }
+// no format check — garbage wallet stored in DB
+```
+
+**Impact**
+Inconsistent data in database. Marginal risk if combined with SEC-001 (signature verification) fix, but inconsistent interface.
+
+**Effort**: 5 min (extract regex to util, apply everywhere)
+**Phase**: Tier 2
+
+---
+
+## MEDIUM SEVERITY ISSUES (9)
+
+### SEC-004: Admin Password Sent in Request Body
+
+**Severity**: MEDIUM
+**Category**: Security
+**Module**: server.js:285, index.html:2703-2706
+**Tier**: 2
+
+**Description**
+Related to SEC-002. Login sends password in JSON body. The password then appears in: (1) request body logs, (2) JS memory, (3) every header.
+
+**Impact**
+If server logs request bodies (for debugging), password is logged. If network is TLS-stripped (MITM), password transits plaintext in headers.
+
+**Effort**: 30 min (part of SEC-002 token fix)
+**Phase**: Tier 2
+
+---
+
+### ARCH-001: No Database Transaction on deleteProposal
+
+**Severity**: MEDIUM
+**Category**: Architecture
+**Module**: db.js:146-149
+**Tier**: 2
+
+```js
+// Two separate queries, no transaction
+await pool.query("DELETE FROM votes WHERE proposal_id = $1", [id]);
+await pool.query("DELETE FROM proposals WHERE id = $1", [id]);
+```
+
+**Impact**
+If first succeeds and second fails: orphaned votes. If reversed order (delete proposals first): FK constraint blocks delete of votes.
+
+**Effort**: 30 min (wrap in transaction)
+**Phase**: Tier 2
+
+---
+
+### ARCH-002: Migration Logic Runs on Every Startup
+
+**Severity**: MEDIUM
+**Category**: Architecture
+**Module**: db.js:38-41
+**Tier**: 2
+
+```js
+// Runs every boot
+await pool.query(`ALTER TABLE proposals ADD COLUMN IF NOT EXISTS threshold ...`);
+```
+
+**Impact**
+Not a bug today, but maintenance trap. As schema grows, startup latency increases. No migration versioning or rollback capability.
+
+**Effort**: 2h (adopt migration tool or implement version table)
+**Phase**: Tier 3 (low priority until schema stabilizes)
+
+---
+
+### OPS-001: Health Check Has No Depth
+
+**Severity**: MEDIUM
+**Category**: Operational
+**Module**: server.js:396-398
+**Tier**: 2
+
+```js
+// Always returns ok, no dependency check
+app.get("/api/health", (req, res) => {
+  res.json({ status: "ok", timestamp: new Date().toISOString() });
+});
+```
+
+**Impact**
+Render health checks report service as healthy even when DB is down. Misleads monitoring and autoscaling.
+
+**Effort**: 30 min (add DB ping, Redis ping, cache age check)
+**Phase**: Tier 2
+
+---
+
+### OPS-002: streamflow.js Uses console.log Instead of Logger
+
+**Severity**: MEDIUM
+**Category**: Operational
+**Module**: streamflow.js:61, 82, 85, 99, 101, 282, 288, 335
+**Tier**: 2
+
+**Description**
+Logger.js (Winston) is set up but not used in streamflow. Blockchain/cache events have no structured format, no service metadata, won't appear in file logs in production.
+
+**Effort**: 5 min (import logger, replace console calls)
+**Phase**: Tier 2
+
+---
+
+### OPS-003: Graceful Shutdown Does Not Close DB Pool
+
+**Severity**: MEDIUM
+**Category**: Operational
+**Module**: server.js:406-411
+**Tier**: 2
+
+```js
+// Closes Redis but not PostgreSQL
+process.on('SIGTERM', async () => {
+  await closeRedis();
+  process.exit(0);
+});
+```
+
+**Impact**
+On Render rolling restarts, active DB queries are aborted mid-flight. Connection leaks accumulate.
+
+**Effort**: 5 min (export pool.end() from db.js, call on SIGTERM)
+**Phase**: Tier 2
+
+---
+
+### BUG-006: totalPool Zero for "all" Mode When Supply Not Loaded
+
+**Severity**: MEDIUM
+**Category**: Logic
+**Module**: index.html:1538-1543
+**Tier**: 2
+
+**Description**
+If `tokenTotalSupply` is 0 (not yet fetched), `getTotalPool("all")` returns 0, and all "all" mode proposals show "threshold not met" incorrectly.
+
+**Impact**
+During cold page load, proposals show incorrect status until supply data loads.
+
+**Effort**: 30 min (show "loading" state instead of false "not met")
+**Phase**: Tier 2
+
+---
+
+### ARCH-003: No Input Sanitization on lockId in Admin Routes
+
+**Severity**: MEDIUM
+**Category**: Architecture
+**Module**: server.js:322, 340
+**Tier**: 2
+
+**Description**
+Admin routes don't validate `lockId` format. Params not validated against base58 format like wallet routes.
+
+**Impact**
+Admin could set a 1000-char name for a key, causing UI issues. Low practical risk (requires auth) but inconsistent.
+
+**Effort**: 5 min (same base58 validation as wallet route)
+**Phase**: Tier 2
+
+---
+
+## LOW SEVERITY ISSUES (5)
+
+### OPS-004: No SIGINT Handler
+
+**Severity**: LOW
+**Category**: Operational
+**Module**: server.js:406-411
+**Tier**: 3
+
+**Description**
+Only `SIGTERM` is handled. Local `Ctrl+C` sends `SIGINT`, no cleanup.
+
+**Effort**: 5 min
+**Phase**: Tier 3
+
+---
+
+### ARCH-004: No Pagination on /api/proposals
+
+**Severity**: LOW
+**Category**: Architecture
+**Module**: server.js:134
+**Tier**: 3
+
+**Description**
+Returns all proposals with all votes in one response. `json_agg` grows unbounded as votes accumulate.
+
+**Impact**
+High proposal volume → large JSON payload on every page load.
+
+**Effort**: 2h (add pagination or separate vote endpoint)
+**Phase**: Tier 3 (until proposal volume warrants it)
+
+---
+
+### ARCH-005: Proposal ID Generated Client-Side Without Crypto
+
+**Severity**: LOW
+**Category**: Architecture
+**Module**: server.js:193
+**Tier**: 3
+
+```js
+// Not cryptographically secure
+const id = Date.now().toString(36) + Math.random().toString(36).slice(2, 8);
+```
+
+**Expected**: `crypto.randomUUID()` or `nanoid`.
+
+**Effort**: 5 min
+**Phase**: Tier 3
+
+---
+
+### BUG-007: buildMergedTimeline Cumulative Calculation Subtle Bug
+
+**Severity**: LOW
+**Category**: Logic
+**Module**: streamflow.js:262-265
+**Tier**: 3
+
+**Description**
+When 3+ locks unlock on exact same timestamp, cumulative calculation may double-count. Only impacts same-second unlocks (unlikely).
+
+**Effort**: 30 min (test with 3 co-dated events)
+**Phase**: Tier 3
+
+---
+
+### FEAT-001: No Proposal Status Persistence
+
+**Severity**: LOW
+**Category**: Feature
+**Module**: db.js (proposals table)
+**Tier**: 3
+
+**Description**
+Proposal "Passed/Failed" status is computed on every read, never persisted. Results change retroactively if `tokenTotalSupply` changes.
+
+**Effort**: 2h (add status column, persist on close)
+**Phase**: Tier 3 (with migration strategy)
+
+---
+
+### FEAT-002: No Audit Log for Admin Actions
+
+**Severity**: LOW
+**Category**: Feature
+**Module**: server.js admin routes
+**Tier**: 3
+
+**Description**
+No record of who deleted what, when. Only logs failures.
+
+**Effort**: 30 min (add logger.info to each admin route)
+**Phase**: Tier 3
+
+---

+### Redis Rate Limiting
+
+The app uses Redis for distributed rate limiting (shared across multiple instances).
+
+- **Production**: Requires a Redis instance. Render provides a Redis addon in the dashboard.
+- **Development**: Falls back to in-memory rate limiting if Redis is unavailable.
+- **Configuration**: Set `REDIS_URL` env var to your Redis connection string.

+
+### Structured Logging
+
+The app uses Winston for structured logging with multiple outputs:
+
+- **Development**: Console output with colors for readability
+- **Production**: Console + file logging (JSON format) to `logs/error.log` and `logs/combined.log`
+- **Configuration**: Set `LOG_LEVEL` env var (`debug`, `info`, `warn`, `error`). Default is `info`.
+
+**Important**: In production, ensure the `logs/` directory exists and is writable. On Render, this is handled automatically by the build script.

+# TokenVotingUtil Roadmap
+
+Strategic vision for stabilizing and enhancing TokenVotingUtil. This roadmap is **not fixed** — it adapts based on sollama58's feedback and priorities.
+
+---
+
+## Phase 1: Stabilize & Harden (Current)
+
+**Goal**: Make the platform production-ready and maintainable.
+
+### Étape 1: Infrastructure Hardening ✓ Ready
+**Duration**: 1-2 weeks (or merge when convenient)
+
+**What**:
+- Fix CORS vulnerability (allowlist from '*')
+- Add Jest test suite (infrastructure coverage)
+- Add Winston structured logging
+- Add Redis-backed rate limiting (distributed, scalable)
+
+**Why**:
+- Security: CORS was open to any origin
+- Reliability: Zero tests meant changes were risky
+- Debuggability: No structured logs for production
+- Scalability: In-memory rate limiting resets on restart
+
+**Status**: PR #1 ready for review
+**Testing**: 34 tests pass (unit + integration)
+**Blockers**: None (independent of other phases)
+
+**Deployment Notes**:
+- New env vars: ALLOWED_ORIGINS, LOG_LEVEL, REDIS_URL (documented in DEPLOYMENT.md)
+- Redis optional (falls back to in-memory)
+- Logs written to `logs/` directory (prod only)
+
+**Next**: Await sollama58 feedback / approval to merge
+
+---
+
+### Étape 2: Voting Logic Audit & Fixes 🟡 Pending Decision
+**Duration**: 1-2 weeks (depends on scope)
+**Blocked By**: Étape 1 approval + decisions below
+
+**What**:
+During code review of Phase 1, we identified 3 bugs in voting logic:
+
+1. **Margin Comparison Bug** (CRITICAL)
+   - Location: `public/index.html:1536`
+   - Issue: `margin >= threshold` should be `margin > threshold`
+   - Example: threshold=5%, margin=5% → currently passes (WRONG)
+   - Fix: 30 min (change 1 operator + 1 test)
+
+2. **Tie Detection Missing** (MEDIUM)
+   - Location: `public/index.html:2050`
+   - Issue: No explicit tie handling when equal votes exist
+   - Example: choice A = 100, choice B = 100 → silent tie
+   - Fix: 30 min (add detection + logging)
+
+3. **Frontend Tally Authority** (ARCHITECTURAL)
+   - Location: Entire voting result calculation
+   - Issue: Results calculated client-side only; no server verification
+   - Question: Should voting tally move to backend?
+   - Impact: Depends on governance trust model
+
+**Three Possible Paths**:
+
+**Option A: Quick Fixes Only** (Safe, Fast)
+- Fix bugs #1 and #2 only (margin, tie detection)
+- Keep frontend tally as-is
+- ✓ 1-2 days, low risk, easy review
+- ✗ Tally authority still client-side
+
+**Option B: Full Backend Tally** (Robust, Complex)
+- Fix bugs #1 and #2
+- Move tally calculation to backend
+- Frontend sends votes, server calculates results
+- ✓ More authoritative, better for governance
+- ✗ 1 week, bigger refactor, frontend changes needed
+
+**Option C: Skip Phase 1 Étape 2** (Defer)
+- Don't fix voting bugs now
+- Focus on other priorities
+- Revisit later when governance goes live
+- ✓ Fastest, lowest risk for now
+- ✗ Bugs remain until fixed
+
+**Question for sollama58**:
+Which path aligns with your vision for TokenVotingUtil?
+- A (quick fixes), B (full backend tally), or C (defer)?
+- Timeline preference?
+- Any other priorities for Phase 1?
+
+**Decision Method**: Issue #1 will ask this explicitly; we implement based on feedback.
+
+---
+
+## Phase 2: Production Ready (Future)
+
+**Goal**: Governance can go live with confidence.
+
+### What (Proposed, pending Phase 1 decisions)
+- Complete Phase 1 Étape 2 work
+- Config externalization (move hardcoded values to env vars)
+- Admin panel enhancements (better proposal management)
+- Documentation for governance operations
+
+### Why
+- Easier to manage multiple token communities
+- Less code changes needed per deployment
+- Clearer admin workflows
+
+### Timeline
+- Starts after Phase 1 complete
+- Depends on Phase 1 feedback
+
+---
+
+## Phase 3: Scale & Enhance (Future)
+
+**Goal**: Support growth and advanced use cases.
+
+### Possible Features (NOT DECIDED YET)
+- **Multi-Tenant Support**: One instance serves multiple token communities
+- **Leaderboard / XP System**: Governance participation tracking
+- **Custom Voting Rules**: Beyond threshold-based
+- **Proposal Templates**: Reduce spam
+- **Advanced Analytics**: Participation metrics
+
+### Timeline
+- 6+ months out
+- Depends on adoption and feedback
+
+### Not in Scope
+- Custom blockchains (Solana only)
+- Token trading/DEX features
+- Smart contract deployment
+
+---
+
+## Decision Dependencies
+
+```
+Phase 1 Étape 1 ✓ Ready for merge
+    ↓
+Phase 1 Étape 2 🟡 Blocked on:
+    - sollama58 feedback on voting bugs
+    - Decision: Path A, B, or C?
+    - Timeline: When to implement?
+    ↓
+Phase 2 🟡 Blocked on:
+    - Phase 1 complete
+    - Budget/resource availability
+    ↓
+Phase 3 🟡 Blocked on:
+    - Phase 2 complete
+    - Clear use cases / demand
+```
+
+---
+
+## Success Criteria
+
+### Phase 1
+- ✓ Infrastructure solid (CORS, tests, logging, rate limiting)
+- ✓ Voting logic bugs fixed (if Path A or B chosen)
+- ✓ sollama58 confident merging to production
+- ✓ No critical bugs blocking governance launch
+
+### Phase 2
+- ✓ Governance can go live
+- ✓ Admin workflows streamlined
+- ✓ Docs clear for operations team
+
+### Phase 3
+- ✓ Multiple communities can use platform
+- ✓ Growth features support adoption
+- ✓ Analytics inform governance participation
+
+---
+
+## How to Influence This Roadmap
+
+1. **Open an Issue** with feedback / priorities
+2. **Comment on Phase 1** with concerns or suggestions
+3. **Request features** (Phase 3 ideas)
+
+This roadmap is **collaboration, not prescription**.
+
+---
+
+## Current Status
+
+| Phase | Étape | Status | Blocker |
+|-------|-------|--------|---------|
+| 1 | 1 (Infrastructure) | ✓ Ready for review | None |
+| 1 | 2 (Voting bugs) | 🟡 Pending decision | Issue #1 feedback |
+| 2 | All | 🟡 Pending Phase 1 | Phase 1 complete |
+| 3 | All | 🟡 Future | Phase 2 complete |
+
+**What's Next?**
+1. sollama58 reviews Phase 1 Étape 1 (PR #1)
+2. We clarify Phase 1 Étape 2 questions (Issue #1)
+3. sollama58 provides feedback
+4. We implement based on decision
+5. Move to Phase 2
+
+---
+
+## Questions?
+
+If anything is unclear:
+- Check `COLLABORATION.md` (how we work)
+- Check `ARCHITECTURE.md` (technical details)
+- Open an issue with questions
+- We'll refine roadmap based on feedback
+
+**Goal**: Transparency. You should know what we're planning and why.
