Description
Related: #33
COVERAGE_GAP_RECOVERY (src/services/open-meteo/open-meteo-service.ts) tells the caller to change a parameter that most tools do not expose:
Switch to a model whose domain includes this coordinate (any global model does), or omit the model to use the default blend. Retrying returns the same response.
It is raised from…

feat(current): expose current weather and air-quality conditions
Use case
A caller asking “what is the temperature, wind, and precipitation right now?” or “what is the AQI now?” must request an hourly time series and then infer which row corresponds to the current instant. That is more work and less precise than the upstream current-condition capability, which is based on 15-minute model data.
Both workflows belong on existing tools:
openmeteo_get_forecastalready owns current and forecast weather for coordinates.openmeteo_get_air_quality…

Description
Spill eligibility and preview selection apply the 80,000-character PREVIEW_CHARS budget only to serialized row objects. Wide unit maps, the canvas_id/table_name/record_count/model fields, and the formatted content[] header are added afterward, so an honestly truncated result can still exceed the…

A non-empty invalid time zone fails upstream, but the server reports it as an invalid variable with variable-name recovery instead of…
