Add soil moisture index view to TUI #10

claude-agent-marvin8 commented 2026年07月01日 10:43:21 +02:00

Adds a soil moisture index view to the TUI, toggled with m. Uses an exponential-decay leaky-bucket model (decay=0.85, ≈4–5 day half-life) applied to daily rainfall totals to approximate soil moisture level for farm management decisions.

Changes

• Database.get_moisture_index() — new DB method computing the leaky-bucket moisture time series, with the same grouping and pagination contract as get_rain
• ChartMode enum and m key binding — toggles the bar chart and stats panel between rainfall and moisture views
• Stats panel header — always shows current mode (Rain/Moisture) and grouping (Daily/Weekly/Monthly/Yearly)
• Tentative moisture entries — _compute_tentative_moisture_entries generates decaying synthetic bars for days since the last DB record, showing soil drying in real time

Closes #9
