Frozen model
Stage 7D A0 FP32 ONNX, with the fixed Stage 7C operating thresholds.
Before you inspect
Specimen intake
Drop one leaf image onto the field desk. Keep the final call human.
The image is processed on this device. RoyaCheck does not upload the raw image for inference, and this MVP does not save the photo with the record.
01
Image intake
Select or capture an image
Use a current landscape image with one complete target leaf visible. Images smaller than 224×224 are routed to not sure.

What this proposal means
Evidence boundary
Validation passed on frozen BRACOL validation data. A one-shot frozen BRACOL internal-holdout readout was completed. This is not field validation; no RoCoLe external readout has been completed.
03
Formal record
Human sign-off
Human disposition
Do not copy the AI automatically. Review the image and choose the formal observation yourself.

Fixed-string card
Local-language fixed-string scaffold
This MVP includes a fixed-string local-language scaffold connected to the current AI proposal and human disposition. Actual Lugisu/Lumasaba wording is pending fluent human validation and is not claimed in this build.
Local-language scaffold pending fluent validation.
Run the normal flow or choose a fixed-string rehearsal. Actual Lugisu/Lumasaba wording is not claimed in this build.
Localization limitation: fixed strings only; no chatbot, no free-form translation, and no claim of validated Lugisu/Lumasaba usability or field readiness.

Evidence and limitations
Internal evidence
On the frozen BRACOL internal holdout, 136 target-class leaves were eligible for target-class routing. The model produced 106 confident target-class outputs and 104 of those 106 were correct. The visible-rust route captured 66 of 95 rust leaves, while 27 of 95 rust leaves were routed to not sure and 2 of 95 rust leaves were routed to no visible rust. Other-condition false-visible-rust routing occurred for 7 of 117 other-condition leaves.
Claim ceiling
Those numbers are internal-holdout evidence only. They are not field validation, not RoCoLe external-transfer evidence, and not challenge-set evidence.
Safety
RoyaCheck does not diagnose a plant, select treatment, recommend pesticide use, explain falling yields, or replace qualified human review. It does not verify that an image is a coffee leaf.
Localization
This technical MVP includes a local-language fixed-string scaffold. Actual Lugisu/Lumasaba wording is pending fluent human validation. Validated localized usability has not been established.
