Field Demo 001: Turning the garden into a digital twin
Today's goal was to ship the first complete SteelThumb field demo slice: a garden reference image, a digital twin preview, a manual grow-area map, plant IDs, notes, and projected overlays.
The shipped slice proves the clickable chain: garden area -> stable plant ID -> note, task, and history. The page is not claiming live autonomy. The reconstruction pipeline is described as the next build layer.
LIVE
What is real
The page is grounded in the current field-demo grow-bag row and reference imagery.
The product story is the actual SteelThumb vertical slice: a real garden mapped into a semantic record.
The PlotTag and grow-bag examples are based on the current field-demo workflow.
MANUAL
What is manual
Grow-area polygons and ellipses are hand-authored in normalized image coordinates.
Plant root positions are demo pins tied to stable plant IDs.
Notes and tasks are seed examples of the intended record.
SIMULATED
What is simulated
Moisture percentage.
Harvest estimate.
Automated health status and water schedule values.
COMING SOON
Coming next
Walkthrough video capture.
PlotTag / AprilTag detection.
COLMAP alignment.
Gaussian splat rendering.
Top-down annotation workflow.
Next engineering step
Replace proxy visuals with promoted field media and keep the same semantic data contract.
The MVP architecture deliberately keeps the semantic model separate from the visual layer. A real photo, a WebGL proxy, or a Gaussian splat can all point at the same GrowArea, PlantInstance, PlotTag, Device, Observation, and Task records.
