# Codebase Concerns
|
|
|
|
**Analysis Date:** 2026-03-12
|
|
|
|
## Project Status: Greenfield
|
|
|
|
**Critical Finding:** This is a greenfield project with no actual implementation code. The repository contains only:
|
|
|
|
- `THE_IDEA.md` - Requirements specification document
|
|
- `.opencode/` - OpenCode/GSD framework configuration
|
|
|
|
**Impact:** There are no code-level technical concerns to document because nothing has been built yet. This document outlines concerns for the future implementation.
|
|
|

|
|
## Implementation Concerns
|
|
|
|
### No Source Code Exists
|
|
|
|
**Issue:** No application code has been implemented
|
|
- Files: None (project has not been initialized with source code)
|
|
- Impact: Cannot assess code quality, patterns, or technical debt
|
|
- Fix approach: Initialize project with proper scaffolding before implementation begins
|
|
|
|
### Missing Project Initialization
|
|
|
|
**Issue:** No package.json, build configuration, or source directories at project root
|
|
- Files: `package.json`, `tsconfig.json`, `src/` missing
|
|
- Impact: No standard development workflow established
|
|
- Fix approach: Run project initialization to create proper project structure
|
|
|

|
|
## Hardware-Specific Concerns
|
|
|
|
### Low-Power Device Targeting
|
|
|
|
**Issue:** Target hardware is Raspberry Pi Zero 2W (limited resources)
|
|
- Device: Pi Zero 2 W with 512MB RAM, single-core ARMv8
|
|
- Concern: UI must be lightweight to run smoothly in Chromium Kiosk Mode
|
|
- Mitigation needed:
|
|
- Minimal JavaScript bundle size
|
|
- Efficient rendering (avoid heavy frameworks if possible)
|
|
- Consider static HTML/CSS over SPA for main interface
|
|
- Lazy-load any heavy components
|
|
|
|
### Dual Display Resolution Support
|
|
|
|
**Issue:** Must support two different display modes
|
|
- 7-inch touchscreen: 1024x600 resolution
|
|
- Full HD remote access: 1920x1080 resolution
|
|
- Concern: Responsive design complexity
|
|
- Mitigation needed:
|
|
- Clear responsive breakpoints
|
|
- Different layouts for touch vs desktop
|
|
- Performance testing on actual hardware
|
|
|

|
|
|
|
## Requirements Complexity
|
|
|
|
### Feature Scope (3 Milestones)
|
|
|
|
**Issue:** Large feature set across three milestones
|
|
- Milestone 1: Modern compact UI
|
|
- Milestone 2: CSV processing and workflow
|
|
- Milestone 3: Network stack
|
|
- Concern: Scope creep and milestone creep
|
|
- Priority: High
|
|
|
|
### Data Types and Processing
|
|
|
|
**Issue:** Multiple sensor data types require handling
|
|
- Rainfall (today, hourly, MAR, yearly)
|
|
- Battery voltage
|
|
- Solar voltage
|
|
- Water level sensors (4-20mA, 0-10vDC)
|
|
- GPS coordinates
|
|
- Mobile network status
|
|
- Concern: Data normalization and storage complexity
|
|
|
|
### Network Protocol Support
|
|
|
|
**Issue:** Multiple transfer protocols specified in requirements
|
|
- FTP, SCP, SFTP, WEBDAV
|
|
- TCP socket connections
|
|
- Concern: Implementation complexity and security
|
|
- Mitigation: Start with simplest protocol (HTTP), add others as needed
|
|
|

|

|
|
## Dependencies at Risk
|
|
|
|
### OpenCode Framework Dependency
|
|
|
|
**Issue:** Project configured to use OpenCode/GSD workflow
|
|
- Package: `@opencode-ai/plugin` v1.2.24
|
|
- Location: `.opencode/package.json`
|
|
- Risk: Vendor lock-in to specific workflow tool
|
|
- Mitigation: Document standard development practices that work independently
|
|
|
|
### Zod in node_modules
|
|
|
|
**Issue:** Zod library present in `.opencode/node_modules/`
|
|
- Purpose: Likely used for configuration validation
|
|
- Concern: Not yet integrated into project (in .)
|
|
- Recommendation: If validationopencode only needed, use zod; otherwise remove dependency
|
|
|

|

|
|
## Missing Infrastructure
|
|
|
|
### No Testing Framework
|
|
|
|
**Issue:** No test files or configuration detected
|
|
- No `jest.config.*`, `vitest.config.*`, or similar
|
|
- No `*.test.*` or `*.spec.*` files
|
|
- Impact: No test coverage for future implementation
|
|
- Priority: High - Testing should be established before implementation
|
|
|
|
### No Linting/Formatting
|
|
|
|
**Issue:** No ESLint, Prettier, or biome configuration
|
|
- Impact: Inconsistent code style as team grows
|
|
- Priority: Medium
|
|
|
|
### No CI/CD Configuration
|
|
|
|
**Issue:** No GitHub Actions, GitLab CI, or similar
|
|
- Impact: No automated testing or deployment
|
|
- Priority: Low (can be added later)
|
|
|

|
|
## Security Considerations (Future)
|
|
|
|
### Network Credentials Storage
|
|
|
|
**Issue:** Requirements mention FTP/SCP credentials
|
|
- Files referenced: `THE_IDEA.md` lines 175-184
|
|
- Concern: Plain-text credentials in configuration
|
|
- Future mitigation:
|
|
- Use environment variables, not config files
|
|
- Consider OAuth/API keys over username/password
|
|
- Encrypt any stored credentials
|
|
|
|
### GPRS/Mobile Network
|
|
|
|
**Issue:** Mobile settings stored in system
|
|
- Location: `THE_IDEA.md` section 1.7
|
|
- Concern: Phone numbers and device IDs stored
|
|
- Future mitigation: Encrypt sensitive station data
|
|
|

|
|

|
## Performance Targets
|
|
|
|
### Startup Time
|
|
|
|
**Target:** Fast enough for Pi Zero 2W Chromium Kiosk
|
|
- Concern: Cold start must be under 3 seconds
|
|
- Mitigation: Minimize JavaScript, use progressive loading
|
|
|
|
### Memory Usage
|
|
|
|
**Target:** Stay within 256MB RAM for UI
|
|
- Concern: Chromium + web app + system services
|
|
- Mitigation: Avoid large in-memory data structures
|
|
