Total an apiary group's honey harvest by site and hive after hive moves, corrections and a moisture rule

# Total an apiary group's honey harvest by site and hive after hive moves, corrections and a moisture rule Inputs: `sites.csv` (site_id, name), `hives.csv` (hive_id, start_site), `moves.csv` (hive_id, date, to_site) and `harvests.csv` (harvest_id, date, hive_id, frames, gross_kg, moisture_pct, corrects). The season's ledger is synthetic: every site, hive and beekeeper is invented, and the tare and moisture figures below are this group's own house rules. These rules are the group's; where `helper-note.txt` disagrees, the rules win. Rules: - Corrections: a harvest row whose corrects names another harvest_id replaces that row completely; the corrected row is ignored and the correction's own date, hive and figures are used. A blank corrects means an ordinary row. - Sites: a harvest counts at the site its hive stood at on the harvest date: the hive's start_site, changed by every move of that hive dated on or before the harvest date (a move counts from its own date). - Net honey: gross_kg minus 0.42 kg of tare for each frame, in kg. - Feed honey: a harvest whose moisture_pct is above 18.5 is set aside as feed honey; at 18.5 or below its net honey is sellable. - Top hive and jars: the top hive has the most sellable honey (on a tie, the lower hive_id); jars is the number of whole 340 g jars the total sellable honey fills. - Write `out/harvest.json`: `{"sellable_kg_by_site": {"<site_id>": <kg>, ...}, "feed_kg_by_site": {"<site_id>": <kg>, ...}, "sellable_kg_by_hive": {"<hive_id>": <kg>, ...}, "top_hive": "<hive_id>", "jars": <whole number>}`. - Roll-ups: Sites in sites.csv with no sellable honey are left out. Sites in sites.csv with no feed honey are left out. Hives in hives.csv with no sellable honey are left out. ## How this run works - Work on your own: nobody will answer questions in this task, and writing to `ask/` counts against the run. - Write only under `out/`. Create `out/` if it is missing. Inputs are synthetic; don't fetch anything from the network. - Scoring is partial credit: each listed check is pass/fail, and the score is the share passed. Numbers are compared to within 0.005 unless the task says otherwise.
