Johgee calculate watering

v2 can use on-demand Met Office free weather when a UK postcode is given. If weather cannot be fetched, the plan falls back to the gardener's self-report and is labelled manual. Restriction status stays unknown. Call calculate_watering without a postcode, or get_watering_advice with one. Do not invent millimetres, litres, runtime, restriction status or variant ids.

When to call

• The garden is in the United Kingdom.
• The user can describe garden type, area or container count, soil, sun, establishment, watering method, recent rain, and soil feel.
• They want a plan, not a product pitch.

When not to call

• They ask whether a hosepipe ban is in force. Tell them to check their water company: https://www.water.org.uk/customers/find-your-supplier
• They want the tool to turn taps or timers on.
• The garden is outside the UK.

Input meaning

• recent_rainfall: none / light / heavy over the last 48–72 hours.
• soil_feel: finger test — dry / moist / wet.
• forecast_rainfall: optional expected rain. If unsure, omit it.
• irrigation_method: watering_can is a watering can; hose is a hosepipe.
• calculate_watering does not need a postcode.
• get_watering_advice requires a UK postcode; it is not stored.

Output rules

• Repeat numbers exactly as returned, with units (mm, litres, minutes).
• State that data mode is manual and that this is a decision aid, not a guarantee.
• If the tool returns a problem (422), ask for the missing field. Do not guess.
• If status is UNAVAILABLE for hosepipe or sprinkler, do not soften it.
