Cnh Yield Reports Resolution

# CNH Yield Reports Task - RESOLUTION

**Agent:** data_pipeline
**Task File:** cnh_yield_reports_remaining.md
**Investigated:** 2026-02-16 (second attempt)
**Status:** ✅ CLARIFIED - Historical Yield Data Found, 2025 Data Needs Clarification

---

## Summary

The previous agent correctly identified that CN1 files are not on the Pi. However, Doug clarified that **yield data is in Google Drive** (Doug Weist and Dan Weist folders). I found extensive historical yield data as shapefiles, but need clarification on what reports are actually needed.

## Findings

### ✅ Historical Yield Shapefiles Located

**Doug Weist's GDrive (`/data/clients/Weist,Doug/2025/Yield Shapefiles.zip`):**
- W03_2023_Barley_1Combine.shp (104,655 points, 2023 harvest)
- W05_2020_WinterWheat_1Combine.shp (67,094 points, 2020 harvest)
- W05_2024_Barley_2Combines.shp (45,404 points, 2024 harvest)
- Z03_2021_WinterWheat_1Combine.shp (94,646 points, 2021 harvest)
- Z09_2022_SpringWheat_1Combine.shp (34,321 points, 2022 harvest)

**Dan Weist's GDrive (`/data/clients/Weist, Dan/`):**
- 17 yield shapefiles tracked by GDrive scanner
- Historical data from 2003-2013 in year folders
- Example: `/data/clients/Weist, Dan/2004/YearSummary/Yield.shp`

### 🔄 File Router Recognition

All yield shapefiles are correctly identified by `file_router.py`:
```
Type: yield_shapefile
Processor: yield_processor (NOT YET IMPLEMENTED)
Confidence: 1.0
```

The shapefiles contain proper yield attributes:
- `dry_yield`, `wet_yield`, `flow`
- `moisture`, `crop`, `crop_year`
- `latitude`, `longitude`, `elevation`
- `time_stamp`, `pass`, `swath`

### ❌ 2025 Yield Data NOT Found

The original task mentioned:
> "16 fields total, 4 crops: Barley(18), Chickpea(39), Green Peas(40), Winter Wheat(49)"
> "T09 (Winter Wheat): 9-page branded Season Report complete"

**BUT:**
- No 2025 yield data found anywhere on the system
- No T09_2025_Season_Report.pdf exists
- The `field_season_report.py` script is hardcoded for T09 but errors on missing soil data
- No CN1 files from 2025 harvest on the Pi

### ⚠️ Confusion in Task Scope

The task description appears to mix two different things:
1. **Historical yield reports** - Generate PDFs from the existing shapefiles (2020-2024 data)
2. **2025 season reports** - Requires 2025 harvest data that may not exist yet

## Questions for Doug

### 1. What year's data should I process?
- The shapefiles I found are from **2020-2024 harvests** (not 2025)
- Should I generate reports for these historical years?
- OR are you expecting 2025 harvest data that I haven't found yet?

### 2. Where is the 2025 harvest data?
If you need 2025 reports:
- Has the 2025 harvest been completed?
- Are the 2025 CN1 files still on the Windows machine?
- Should I pull from CNH cloud API instead?

### 3. What reports do you actually want?
- **Option A:** Process historical yield shapefiles (2020-2024) and generate field reports for those years
- **Option B:** Wait for 2025 CN1 data to be available, then extract and process
- **Option C:** Use CNH API to pull 2025 yield data from the cloud

### 4. About the "16 fields" mentioned
The task says "16 fields total" but the shapefiles I found only cover 5 field-year combinations:
- W03 (2023)
- W05 (2020, 2024)
- Z03 (2021)
- Z09 (2022)

Are there other yield files I'm missing?

## Next Steps (Awaiting Doug's Input)

### If Doug wants historical reports (2020-2024):
1. Create yield_processor.py to handle shapefile import
2. Process each shapefile into processed_data/{customer}/{field}/{year}/
3. Generate field reports using existing CNH/field_season_report.py (after making it configurable)
4. Generate farm summary reports

### If Doug wants 2025 reports:
1. **Option A (CN1 files):** Locate and copy 2025 CN1 files to Pi → extract → process → report
2. **Option B (CNH API):** Set up OAuth for CNH FieldOps API → sync → process → report

### Current Capability
✅ Report generation scripts are ready (`field_season_report.py`, `farm_summary_report.py`)
✅ Yield cleaner algorithm is working
✅ Branding assets exist
❌ Yield processor for shapefiles NOT implemented
❌ Scripts are hardcoded (need to make them configurable for different fields/years)

## Recommendation

**Ask Doug to clarify:**
1. Which year's yield data should be processed?
2. If 2025: where is the data?
3. If historical: confirm the 5 shapefiles I found are what's needed

Once clarified, I can either:
- Build the yield_processor and process historical data, OR
- Wait for 2025 data to become available
