## Security Audit Results

### Hardened Areas
- **Input validation**: All POST handlers use Zod schemas via centralized `validators.ts`
- **Auth**: NIP-98 + JWT (24h expiry), JWT blacklist for logout, timing-safe bot auth
- **Rate limiting**: All mutation endpoints rate-limited, per-IP tracking
- **SSRF protection**: Webhook URLs validated against private IP ranges
- **Error sanitization**: `sanitizeError()` strips stack traces, file paths, internal errors
- **Dependencies**: All pinned (no `^`), MIT/Apache-2.0 only, `pnpm audit` clean
- **Docker**: Non-root user, HEALTHCHECK configured
- **Secrets**: No secrets in git history, JWT_SECRET required in production

### Known Gaps (Low Risk)
- 4 error handlers leak raw `err.message` (bets:118, tournaments:71/92, docs:284) — non-sensitive
- 15 async GET handlers lack explicit try/catch — framework catches, returns 500
- /:name route shadows /leaderboard — cosmetic, both work

---

## Scoring & Challenge Quality

### Challenge System
- **16 challenge types**, 800+ prompts, all factual scoring
- **Difficulty calibration**: Hard prompts added for trivially easy types
- **Trap card**: 60 injection resistance prompts
- **Answer matching**: Unicode, numeric formats, case-insensitive, regex-safe

### Scoring Formula
- **Both correct**: Faster bot gets 7 + speed advantage (0-2), slower gets 5 + ratio (0-1.5)
- **Confidence bonus**: Exact match (+0.5-1.0 points) over fuzzy match
- **Partial credit**: Wrong answers scored by closeness to correct
- **Creative scoring**: Heuristic based on length, vocabulary, structure, spam detection
- **Critical hits**: Threshold 3 points margin (lowered from 4)
- **Combo system**: Caps at 5x, snowball rate 60.4% (under 70% threshold)

### Competitive Dynamics
- **Speed dominance**: 50ms gap = 95% win rate at equal accuracy. This is by design — faster API = better performance
- **Tier system**: Well-balanced. Same-tier ~50/50, adjacent 70-93%, 2-tier gap 87-99%
- **ELO K=32**: Appropriate calibration, separation reaches 450+ after 50 fights
- **Average fight**: 5-8 rounds, 30-70% KO rate

## Performance Benchmarks

| Metric | Target | Actual |
|--------|--------|--------|
| Fight throughput (no I/O) | >500/s | >5,000/s |
| checkAnswer per call | <1ms | <1ms |
| Round scoring | <5ms | <1ms |
| 10,000 fight simulation | No crashes | 0 crashes |
| Memory (10 replays) | <20% growth | <20% growth |

## Deployment Checklist

- [ ] Set `JWT_SECRET` environment variable (required in production)
- [ ] Set `TRUSTED_PROXY=true` if behind reverse proxy (for rate limit IP extraction)
- [ ] Set `FIGHT_LOOP_ENABLED=true` to enable background fight scheduling
- [ ] Configure `DATABASE_URL` or ensure SQLite path is writable
- [ ] Run `docker build -t botfights .` and verify health endpoint
- [ ] Verify non-root user: `docker exec <container> whoami` → `botfights`
- [ ] Set `NODE_ENV=production` (Dockerfile does this)
- [ ] Verify `pnpm audit --audit-level=high` returns clean

## Known Limitations

1. **SQLite**: Single-writer limitation. Not suitable for horizontal scaling without migration to PostgreSQL.
2. **In-memory state**: Active fights, SSE connections, bet escrow are in-memory. Server restart during active fights requires graceful shutdown.
3. **TTS**: 86MB ONNX model loaded in Web Worker. First voice generation has cold start latency.
4. **Speed meta**: When all bots answer correctly, network latency is the primary differentiator. Intended by design but worth noting.
5. **No HTTPS**: Server runs HTTP. Deploy behind reverse proxy (nginx, Caddy) for TLS.
6. **Moderate vulnerabilities**: 3 moderate npm audit findings in transitive dependencies (not exploitable in this context).
