v0.2 AOI: bbox 37.20, 29.60, 38.60, 30.60
Two-epoch extent of centre-pivot irrigation in the Wadi As-Sirhan basin, Saudi Arabia, from Landsat NDVI. Circular fields watered from a fossil aquifer expanded across bare desert through the 1990s and 2000s; groundwater policy and depletion have since retired many of them.

The contract
legacy dialect
Read from this recipe's own declarations — parameters:,
outputs:, requires:, and the ops its layers name. Not from its
style blocks and not from any benchmark: a colour ramp is not a contract, and a measured
run is evidence about one AOI rather than a domain.
Parameters
The legacy dialect has no typed parameter schema. Read the folia.yaml for what this recipe takes; nothing here can type-check it.
Outputs
| output | kind | layer | what it is |
|---|---|---|---|
active_baseline |
answer | answer/active-baseline |
Early-expansion proxy irrigated pixel count. |
active_recent |
answer | answer/active-recent |
Recent proxy irrigated pixel count. THE answer, read against the baseline. |
ndvi_change |
raster | compute/ndvi-change |
dNDVI raster, recent minus baseline (show-your-work). |
Capabilities it requires
The legacy dialect has no requires: block.
Where it runs
- Browser preview does not run here answer/active-baseline: layer type "answer" is not one folia-view parses; answer/active-recent: layer type "answer" is not one folia-view parses; compute/active-baseline: carries an unsubstituted ${...} template; and 7 more
- Local CLI (folia run) runs here runs locally through the legacy (no spec_version) parser
- Operated fleet (POST /plan, /run) runs here legacy dialect: a lock binds by the cut's layer names, not by digest
