# Project State

**Project:** TCKRTUIYO - RTU Web Interface  
**Created:** 2026-03-13  
**Status:** Roadmap Created - Awaiting Phase 1 Planning

---

## Project Reference

**Core Value:** Real-time rainfall and sensor monitoring with local display and server data transmission.

**Target Hardware:** Raspberry Pi Zero 2 W / 3B + 7" capacitive touchscreen (1024x600)

**Critical Constraints:**
- Performance: Must run smoothly on Pi Zero 2 W (1GHz quad-core, 512MB RAM)
- Bundle size: <200KB initial JS gzipped
- Display: Fixed 1024x600 for kiosk, responsive for Full HD remote
- Browser: Chromium Kiosk Mode only

### Phase Status

| Phase | Status | Progress | Started | Target Complete |
|-------|--------|----------|---------|-----------------|
| 1. Foundation & Dashboard | Not started | 0% | - | - |
| 2. Settings Framework & Core Configuration | Blocked | 0% | - | - |
| 3. Data Management & Network Stack | Blocked | 0% | - | - |

## Current Focus

**Next Action:** Plan Phase 1 - Foundation & Dashboard

**Phase 1 Goal:** Users can view real-time rainfall, voltage, and station status on a modern, performant dashboard optimized for 7" touchscreen display.

**Key Deliverables:**
- Modern dashboard with real-time sensor display
- Performance optimization for Pi Zero 2 W (<200KB bundle)
- Touch-optimized UI (44px+ targets)
- Dual-mode display (1024x600 kiosk + Full HD remote)
- Navigation to Settings, Calibration, and Flash Memory

---

## Performance Metrics

**Bundle Size Budget:**
- Current: N/A (not built yet)
- Target: <200KB gzipped initial JS
- Limit: 170KB for dashboard to leave buffer

**Performance Targets:**
- LCP: <2 seconds on Pi Zero 2 W
- Touch targets: Minimum 44px
- Data refresh: 1-5 second intervals with debouncing

**Quality Gates:**
- [ ] Dashboard loads on actual Pi Zero 2 W hardware
- [ ] Memory bounded (no unbounded growth over 24h)
- [ ] Touch optimized (tested with finger on 7" display)
- [ ] Performance budget met (<170KB initial JS)

## Accumulated Context

### Decisions Made

| Date | Decision | Rationale |
|------|----------|-----------|
| 2026-03-13 | 3-phase coarse roadmap | Matches granularity config, natural boundaries |
| 2026-03-13 | Dashboard-first approach | Core value + early performance validation |
| 2026-03-13 | React 19 + Vite 8 + Tailwind 4 | Research-validated stack for embedded kiosk |

### Open Questions

- Specific CSV library selection for Phase 3 (needs Web Worker compatibility)
- Network protocol prioritization (FTP/SCP/SFTP/WEBDAV - all needed?)
- Hardware API endpoint contracts (coordinate with Python backend)

### Technical Debt

None yet - project initialization complete.

### Known Blockers

None - ready to begin Phase 1 planning.

## Session Continuity

### Last Session
- **Action:** Roadmap creation
- **Outcome:** 3-phase roadmap created with 35/35 requirements mapped
- **Artifacts:** ROADMAP.md, STATE.md, REQUIREMENTS.md updated

### Next Expected Session
- **Action:** `/gsd-plan-phase 1`
- **Goal:** Create executable plans for Phase 1: Foundation & Dashboard
