## Rules
- Boolean header/section presence only. No yield/condition numbers stored.
- Primary header token: `Corn for Grain Area Harvested, Yield, and Production`.
- Bare “indicated” rejected (false friends in fruit/nut narrative).
- Header presence ≠ eligible harvest season.

## Crop Production TXT (n=110)
- release types: {'ORDINARY_CANDIDATE': 110}
- ordinary + corn yield table header: **64**
- by month (ordinary+header): {'08': 17, '09': 17, '10': 14, '11': 16}
- by calendar year (ordinary+header): {'2010': 4, '2011': 4, '2012': 4, '2013': 3, '2014': 4, '2015': 4, '2016': 4, '2017': 4, '2018': 4, '2019': 4, '2020': 4, '2021': 4, '2022': 4, '2023': 4, '2024': 4, '2025': 3, '2026': 2}

## Still UNKNOWN
`eligible_harvest_seasons` — need revision-opportunity pairing, harvest-season mapping, survey-regime comparability, historical availability. Progress corn G+E presence scan still pending.

## Next
1. Map Aug→Sep→Oct→Nov revision opportunities per harvest season (metadata only).
2. Progress G+E header presence for predictor side.
3. Return exact N / season list / exclusions — or `H01_A_FEASIBILITY_INSUFFICIENT` if N<12 under predeclared rules.
