OCR Strategy + +**Question**: Which OCR engine for production? + +**Tesseract** (Current): +- ✅ Free forever +- ✅ Already working (85% confidence) +- ❌ No handwriting support +- ✅ Privacy (local processing) + +**Google Cloud Vision** (Recommended): +- ✅ Free 1,000 pages/month +- ✅ Handwriting support +- ✅ Faster (1-2s vs 2-3s) +- ✅ Better accuracy +- ⚠️ Cost after free tier: $1.50/1,000 pages + +**Recommendation**: +- Use Tesseract for development/testing +- Add Google Vision for production (handwriting critical for marine logs) +- Use hybrid mode (auto-fallback) for reliability + +### 3. Authentication Strategy + +**Question**: Simple JWT or OAuth integration? + +**Simple JWT**: +- ✅ Fast to implement (4-6 hours) +- ✅ No external dependencies +- ⚠️ Manual user management + +**OAuth (Google/Microsoft)**: +- ⚠️ More complex (12-16 hours) +- ✅ Better UX (SSO) +- ✅ No password management + +**Recommendation**: Start with simple JWT, add OAuth later if needed + +--- + +## Risk Assessment + +### High Risks + +1. **Meilisearch Authentication** (Current) + -

File System Constraints +- **Executable location**: ONLY `/tmp/` (all code, native modules) +- **Persistent storage**: `~/navidocs/` (database, uploads, logs, config) +- **Persistence risk**: `/tmp` may be cleared on reboot +- **Security risk**: `/tmp` is readable by other StackCP users + +### 2. Service Constraints +- **No local Redis**: Must use Redis Cloud (free 30MB tier) +- **No local Tesseract**: Must use Google Cloud Vision API (free 1K pages/month) +- **Meilisearch**: Already running on server (bonus) +- **Process manager**: StackCP Node.js Manager (GUI-based) OR manual (nohup) + +### 3. Development Constraints +- **npm execution**: Must use `/tmp/node /path/to/npm-cli.js` wrapper +- **Native modules**: Must compile in `/tmp` (better-sqlite3, bcrypt) +- **Path configuration**: All paths must be environment-configurable +- **Deployment**: Code from Git to `/tmp`, data backups to `~` + +--- + +## Architectural Impact + +### Code Changes Required (2-3 days) +1.

Create deployment runbook + +**Total Effort**: 5-7 days focused work + +--- + +## Key Questions for Debate + +### For Security Expert: + +1. **Risk Assessment**: `/tmp/navidocs` is readable by other StackCP users + - Threat: Source code exposure (including algorithm logic) + - Threat: `.env` symlink in `/tmp` could expose secrets + - Mitigation: Keep secrets in `~/navidocs/.env` (noexec but protected), symlink carefully + - **Question**: Is this acceptable risk for MVP, or blocker requiring VPS migration? + +2. **External Service Security**: Redis Cloud + Google Vision API + - Benefit: Managed services, professional security + - Risk: Network dependency, potential service compromise + - **Question**: Does cloud-first approach meet security requirements? + +3. **Code Integrity**: `/tmp` persistence risk + - Risk: Code could be cleared, replaced, or tampered with + - Mitigation: Daily checksums, auto-recovery from Git + - **Question**: Can we trust code integrity in `/tmp`? + +### For OCI Architect: + +1. **Container Alternative**: Should we abandon StackCP for containerized deployment? + - Option A: Docker on StackCP (if supported) + - Option B: Migrate to container hosting (Fly.io, Railway, etc.) + - Option C: DigitalOcean App Platform (container-based) + - **Question**: Is the StackCP complexity worth it vs. $5/month VPS? + +2. **Architecture Portability**: How to maintain deployment flexibility? + - Current: Local dev, StackCP prod + - Future: VPS, Kubernetes, serverless? + - **Question**: Should we design for StackCP OR design agnostic with StackCP adapter? + +3. **Operational Complexity**: Is this maintainable long-term? + - Custom scripts: checkpoint, health checks, recovery + - Two-location deployment: `/tmp` + `~` + - Manual monitoring: /tmp persistence + - **Question**: Does this operational overhead scale? + +### For Tech Lead: + +1. **Developer Experience**: How does this affect development workflow? + - Local dev: Standard npm, relative paths + - StackCP deploy: Wrapper scripts, absolute paths, manual recovery + - **Question**: Can we maintain DX while supporting StackCP? + +2. **Testing Strategy**: How to test StackCP-specific scenarios? + - Unit tests: Path configuration + - Integration tests: Checkpoint/restore + - E2E tests: Deployment on fresh StackCP account + - **Question**: What's the minimum viable test coverage? + +3. **Rollout Plan**: How to phase this in? + - Phase 1: Core path configuration (blocks everything else) + - Phase 2: Operational scripts (enables deployment) + - Phase 3: Documentation (enables users) + - Phase 4: Beta test on StackCP (validates assumptions) + - **Question**: Can we ship without full StackCP support first? + +--- + +## Three Paths Forward + +### Path A: Full StackCP Adaptation (5-7 days) +**Pros**: +- Use existing hosting (no new costs) +- Learn shared hosting constraints (educational) +- Meilisearch already running (bonus) + +**Cons**: +- Significant architecture changes +- Operational complexity (checkpoint scripts, monitoring) +- Security risks (`/tmp` exposure, external services) +- Technical debt (StackCP-specific code) + +**Recommendation**: Only if StackCP hosting is **must-have** constraint + +--- + +### Path B: Hybrid Approach (3-4 days) +**Pros**: +- Design path-agnostic architecture (good practice anyway) +- Support StackCP as deployment option (not primary) +- Maintain standard development workflow +- Easy migration to VPS later + +**Cons**: +- Still requires StackCP scripts and documentation +- Testing complexity (multiple environments) +- Partial investment in StackCP-specific tooling + +**Recommendation**: Best balance of flexibility and investment + +--- + +### Path C: Abandon StackCP, Use VPS (1 day) +**Pros**: +- Standard deployment (PM2, systemd, local services) +- Better security (isolated environment) +- Simpler operations (single code location) +- Lower technical debt +- Easier to document and support + +**Cons**: +- Additional cost ($5-10/month DigitalOcean/Linode) +- Need to manage VPS (updates, security patches) +- Lose Meilisearch bonus (need to install) +
